I. INTRODUCTION
1. By this action, we take the necessary steps to implement certain decisions of the World Radiocommunication Conferences held in 2015 (WRC-15) and 2019 (WRC-19).  This action consists of two components:  1) an Order that amends part 2 of the Commission’s rules to make nonsubstantive, editorial revisions to the Commission’s Table of Frequency Allocations (Allocation Table), primarily to reflect decisions from the Final Acts World Radiocommunication Conference 2019 (WRC-19 Final Acts); and 2) a Notice of Proposed Rulemaking that proposes to amend the Allocation Table and related service rules to implement certain radiofrequency allocation decisions from the Final Acts World Radiocommunication Conference 2015 (WRC15 Final Acts). See International Telecommunication Union (ITU), Final Acts WRC-15 (2016) (WRC15 Final Acts), http://handle.itu.int/11.1002/pub/80d4e1c0-en; ITU Final Acts WRC-19 (2020) (WRC-19 Final Acts), http://handle.itu.int/11.1002/pub/813b5921-en; and 47 CFR § 2.106.

2. In the Order (WRC-19 Admin Order), we revise the Allocation Table by updating the International Table of Frequency Allocations (International Table) portion to reflect the International Telecommunication Union’s (ITU’s) Table of Frequency Allocations in its Radio Regulations (Edition of 2020) (Radio Regulations) and by making updates and corrections in the United States Table of Frequency Allocations (U.S. Table) portion. 47 CFR § 2.106.  See ITU Radio Regulations, http://handle.itu.int/11.1002/pub/814b0c44-en.  All citations to the ITU Radio Regulations in this document refer to the Edition of 2020 unless otherwise stated.  Id., Vol. 1, at III.  The United States Table of Frequency Allocations (U.S. Table) is subdivided into the Federal Table of Frequency Allocations (Federal Table, column 4 of § 2.106) and the nonFederal Table of Frequency Allocations (non-Federal Table, column 5 of § 2.106).  The Federal Table is administered by the National Telecommunications and Information Administration (NTIA) and the non-Federal Table is administered by the Commission.  47 CFR § 2.105(a).  The International Table and Federal Table are included in the Allocation Table for informational purposes only.  47 CFR §§ 2.104(a), 2.105(d)(3).
  These ministerial actions do not modify or otherwise change the Commission’s rules with respect to any party’s underlying rights or responsibilities.
3. In the Notice of Proposed Rulemaking (WRC-15 Notice), we propose to amend parts 2, 25, 74, 78, 90, 97, and 101 of the Commission’s rules to implement certain of the remaining allocation decisions from the WRC15 Final Acts concerning portions of the radio spectrum between 5330.5 kHz and 29.5 GHz, make other allocation changes, and make related updates to our service rules in this frequency range.  The WRC-15 Notice follows the WRC-15 Admin Order, Amendment of Parts 1, 2, 15, 27, and 95 of the Commission’s Rules to Make Non-Substantive Editorial Revisions to the Table of Frequency Allocations and to Various Other Rules, Order, 34 FCC Rcd 12830 (2020) (WRC15 Admin Order).
 which made nonsubstantive, editorial revisions to the Allocation Table and to other related rules. All references to Title 47 of the Code of Federal Regulations (CFR) refer to the annual edition, which was revised as of October 1, 2021.  47 CFR § 2.106.  
  Many of these proposals are based on the National Telecommunications and Information Administration’s (NTIA’s) recommendations for national implementation of the WRC-15 Final Acts. Infra note 15.  The Federal Communications Commission (FCC), an independent agency, administers nonFederal radio spectrum, and NTIA, an agency of the U.S. Department of Commerce, administers Federal radio spectrum.  NTIA sets forth regulations for Federal use of the radio spectrum within its Manual of Regulations and Procedures for Federal Radio Frequency Management (NTIA Manual).  47 CFR §§ 2.1(c), 2.105(a).
  Collectively, our proposals are designed to harmonize our spectrum allocations with and conform our rules to the WRC-15 Final Acts to the extent that doing so would better meet domestic requirements.
II. EXECUTIVE SUMMARY
4. In the WRC-19 Order, we take non-substantive, editorial actions to update the Commission’s Allocation Table, including removing expired text and correcting errors.  In the WRC-15 Notice, we propose to implement certain of the allocation decisions from the WRC15 Final Acts, make other allocation changes, and make related updates to our service rules, including those for the amateur radio, cable television relay, fixed microwave, private land mobile, and satellite services, and for aural broadcast auxiliary and television broadcast auxiliary stations.  Specifically, we seek comment on:
Satellite Issues
• Providing satellite-based search and rescue systems with protection from out-of-band emissions in the 406406.1 MHz band by adding footnote US265 and revising section 90.265 to prohibit new fixed and mobile service assignments in the adjacent 100 kilohertz.
• Allocating the 410-420 MHz band to the space research service (space-to-space) on a secondary basis for non-Federal use, limited to communication links with an orbiting, manned space vehicle.
• Providing for Global Flight Tracking by allocating the 1087.7-1092.3 MHz sub-band to the aeronautical mobile-satellite (route) service (Earth-to-space) on a primary basis for Federal and nonFederal use, limited to space station reception of existing automatic dependent surveillancebroadcast (ADS-B) emissions from aircraft. 
• Whether to allocate the 7190-7235 MHz band to the space research service (Earth-to-space) and the 71907250 MHz band to the Earth exploration-satellite service (Earth-to-space) on a secondary basis for nonFederal use.
• Whether to allocate the 9.2-9.3 GHz and 9.9-10.4 GHz bands to the Earth exploration-satellite service (active) on a primary basis for Federal use and on a secondary basis for nonFederal use and add several footnotes that will limit the impact of this new allocation on certain existing allocations.
• Revising footnote NG62 to permit grandfathered fixed stations in the 28.529.1 GHz and 29.25-29.5 GHz bands to operate on a secondary basis; update footnote US139 and the related service rules because incumbent fixed stations in the 18.3-19.3 GHz band no longer have primary status; and seek comment on whether the secondary non-Federal fixed-satellite service (space-to-Earth) allocation in the 18.142-18.3 GHz band should be raised to coprimary status with the fixed service.
• Deleting the primary radionavigation-satellite service allocation from the 149.9-150.05 MHz and 399.9400.05 MHz bands. 
Terrestrial Issues
• Allocating the 5351.5-5366.5 kHz (60 meter) band to the amateur service on a secondary basis, on whether four existing channels should continue to be made available for amateur use, and on appropriate limits for 60 meter band operations.
• Updating the coordination and contact information for amateur stations operating in previously defined areas of the 420-450 MHz (70 centimeter) band.
• Revising footnote US288 to authorize on-board communication stations to use three new 12.5 kilohertz channels/channel pairs nationwide, and five internationally-harmonized 6.25 kilohertz channels and channel pairs at coastal and certain inland ports; and revising footnote US287 to allocate several frequency bands between 457 MHz and 468 MHz totaling 231.25 kilohertz to the maritime mobile service, limited to on-board communication stations.
• Deleting the broadcasting service allocation from the 700 MHz band.
• Adding a new footnote US78 to the 960-1164 MHz band to recognize Federal use by military Identification Friend or Foe (IFF) systems on center frequencies 1030/1090 MHz.  
III. BACKGROUND
5. The ITU When we refer to the ITU in this document, we are generally referring to ITU Radiocommunication Sector (ITUR).  The work of ITU-R is organized and coordinated by the Director of the Radiocommunication Bureau (referred to as the “Bureau” in the ITU Radio Regulations, including the International Table).  Under its constitution, the ITU is charged with allocating bands of the radiofrequency (RF) spectrum, allotting radio frequencies, and registering RF assignments in order to avoid harmful interference between radio stations of different countries.  The ITU constitution also provides that world radiocommunication conferences “shall normally be convened every three to four years” to consider specific radiocommunication matters.  See Constitution and Convention of the International Telecommunication Union adopted by the 2018 Plenipotentiary Conference (published in Basic Texts, 2019), http://handle.itu.int/11.1004/020.1000/5, at 5, 21, 90.  See also the ITU Radiocommunication Sector’s homepage, http://www.itu.int/en/ITU-R (last visited Feb. 28, 2022).
 convenes a World Radiocommunication Conference (WRC) typically every three to four years to address international spectrum use.  Specifically, the ITU allocates frequency bands to various radio services generally on either a worldwide or Regional basis and enters these radio services in its Table of Frequency Allocations (which is reflected in section 2.106 of our rules as the International Table) as part of the Radio Regulations. The ITU may also include allocation use conditions, which are specified in international footnotes to the Allocation Table.

6. The Commission conducted its primary preparations for WRC-15 via its 2015 World Radiocommunication Conference Advisory Committee (WAC), which held eight public meetings between August 9, 2012, and May 20, 2015, to evaluate and approve recommendations and preliminary views that were later submitted for Commission consideration. The WAC was chartered under the Federal Advisory Committee Act (FACA) to provide the Commission with advice, technical support, and recommended proposals for WRC-15.  The Commission published the committee’s recommendations for public comment.  After consideration by the U.S. Government, many of the recommendations became a part of the U.S. views and draft proposals.  For the Commission’s WRC-15 homepage, see https://www.fcc.gov/wrc-15 (last visited Feb. 28, 2022).
  The ITU held a conference preparatory meeting (CPM) from March 23 through April 2, 2015, to prepare and approve a report on the technical, operational, and regulatory/procedural matters relevant to the WRC-15 agenda. See ITU Radiocommunication Sector “CPM Report on technical, operational and regulatory/procedural matters to be considered by the World Radiocommunication Conference 2015” (CPM Report to WRC-15), https://www.itu.int/pub/R-ACT-CPM-2015.
  In addition, the United States worked with other nations to craft common proposals for Region 2 (North and South America). See “U.S. WRC-15 Contributions to CITEL PCC.II” (updated on 8/7/2015), https://www.fcc.gov/general/us-contributions-sent-citel-pccii.
  By August 27, 2015, the United States had provided its contributions to the Inter-American Telecommunication Commission (CITEL), which then provided the Region 2 proposals to WRC-15. See CITEL’s WRC-15 Inter-American Proposals (IAPs) at https://www.fcc.gov/general/citel-inter-american-proposals-iap.

7. The ITU convened WRC-15 from November 2 to November 27, 2015, in Geneva, Switzerland, with 162 Member States, including the United States, participating. See ITU Press Release captioned “World Radiocommunication Conference allocates spectrum for future innovation,” Nov. 27, 2015, http://www.itu.int/net/pressoffice/press_releases/2015/56.aspx#.WjL1sfCnHcs.  For the ITU’s WRC15 homepage, see https://www.itu.int/en/ITU-R/conferences/wrc/2015/Pages/default.aspx (last visited Feb. 28, 2022).
  WRC-15 addressed more than 40 topics related to frequency allocation and frequency sharing for the efficient use of spectrum and orbital resources, and adopted allocation changes that affect both Federal and nonFederal entities. “Results and implications of World Radiocommunication Conference, 2015,” https://www.itu.int/en/ITU-R/seminars/rrs/2017-Africa/Documents/Plenary/03_%20WRC-15%20Outcomes.pdf (last visited Feb. 28, 2022).
  The ITU published the decisions made at WRC-15 as the WRC-15 Final Acts and subsequently revised the Radio Regulations to incorporate these decisions. ITU Radio Regulations (Edition of 2016), Vol. 1, Article 5 (titled “Frequency allocations”), at 37, section IV (titled “Table of Frequency Allocations”) at 43, https://www.itu.int/pub/R-REG-RR-2016.
  On September 10, 2018, NTIA submitted its recommendations for national implementation of the WRC15 Final Acts to the Commission. Letter from Peter A. Tenhula, Acting Associate Administrator, Office of Spectrum Management, NTIA, to Julius P. Knapp, Chief, FCC Office of Engineering and Technology, dated Sept. 10, 2018 (NTIA WRC-15 Implementation Recommendations).

8. On December 23, 2019, the Chief, Office of Engineering and Technology and the Managing Director released the WRC-15 Admin Order, which reflected the WRC-15 changes to the International Table and made other nonsubstantive, editorial changes to the Commission’s rules, including revisions to the Federal Table that did not require notice and comment. Supra notes 3 and 5.  WRC-15 Admin Order, paras. 9-14 (Revisions to the Federal Table).

9. The Commission has already considered certain of the WRC-15 allocation decisions in six different proceedings. Amendment of the Commission's Rules With Regard to the 3650-3700 MHz Government Transfer Band, ET Docket No. 98-237, First Report and Order and Second Notice of Proposed Rule Making, 15 FCC Rcd 20488 (2000) para. 1 (FCC 00-363); Expanding the Economic and Innovation Opportunities of Spectrum Through Incentive Auctions, GN Docket No. 12-268, Report and Order, 29 FCC Rcd 6567, 6705-07 paras. 317-321 (2014); Order, 32 FCC Rcd 6916, 6917-19 paras. 4-5 (2017); Amendment of the Commission’s Rules with Regard to Commercial Operations in the 35503650 MHz Band, GN Docket No. 12-354, Report and Order and Second Further Notice of Proposed Rulemaking, 30 FCC Rcd 3959, 397074 paras. 30-43 (2015); Facilitating Shared Use in the 3100-3550 MHz Band, WTB Docket No. 19-348, Second Report and Order, Order on Reconsideration, and Order of Proposed Modification, 36 FCC Rcd 5987-88, 5995-97 paras. 1, 17-19 (2021); Amendment of Parts 1, 2, 15, 90 and 95 of the Commission’s Rules to Permit Radar Services in the 76-81 GHz Band, ET Docket No. 15-26, Report and Order, 32 FCC Rcd 8822, 8827-29 paras. 10-12 (2017); and Amendment of Parts 2 and 25 of the Commission’s Rules to Facilitate the Use of Earth Stations in Motion Communicating with Geostationary Orbit Space Stations in Frequency Bands Allocated to the Fixed Satellite Service, IB Docket No. 17-95, Report and Order and Further Notice of Proposed Rulemaking, 33 FCC Rcd 9327, 9337-38, 9340, 9349, 9354 paras. 32-33, 44, 66, 89 (2018).
  Specifically, the Commission has revised its rules to provide for mobile broadband use in the 614-698 MHz and 34503700 MHz bands, 47 CFR part 27, subpart N, 600 MHz Band, §§ 27.1300-27.1321, subpart Q, 3.45 GHz Service (3450-3550 MHz), §§ 27.1600-27.1607; 47 CFR part 90, subpart Z, Wireless Broadband Services in the 3650-3700 MHz Band, §§ 90.1301-90.1338; 47 CFR part 96, subpart A, Citizens Broadband Radio Service (3550-3700 MHz), § 96.11.  WRC-15 identified the 614-698 MHz, 3.33.6 GHz, and 3.63.7 GHz bands for International Mobile Telecommunications (IMT), which is generally known as mobile broadband in the United States, through its adoption of footnotes 5.308A, 5.431B, and 5.434, respectively.  47 CFR § 2.106 footnotes 5.308A, 5.431B, and 5.434.
 vehicular and airport radar applications in the 76-81 GHz range, 47 CFR part 95, subpart M, The 76-81 GHz Band Radar Service, §§ 95.3301-95.3385.
 and earth stations in motion (ESIMs) in the 10.95-11.2, 11.45-12.2, 14-14.47, 19.7-20.2, and 29.530 GHz bands. 47 CFR §§ 25.115, 25.202, 25.209, 25.228.  The frequency bands listed that pertain to ESIMs contain a reference to footnote 5.484B, which states that “Resolution 155 (WRC-15) shall apply.”  This resolution states, inter alia, that ESIMs on board unmanned aircraft in Region 2 may communicate with geostationary satellites in the fixedsatellite service (GSO FSS) in the 10.95-11.2, 11.45-12.2, 1414.47, 19.7-20.2, and 29.530 GHz bands for the control and nonpayload communications (CNPC) of unmanned aircraft systems (UAS) and that CNPC links relate to the safe operation of UAS.  Footnote 5.527A states that the operation of ESIMs is subject to Resolution 156, which pertains to ESIMs communicating with GSO FSS satellites in the 19.720.2 and 29.5-30 GHz bands for nonsafety-of-life applications.  In footnote NG527A and its part 25 rules, the Commission did not limit ESIMs to safety-of-life applications in any frequency band, made additional frequency bands available to ESIMs operating with GSO FSS satellites, and made most of the same frequency bands available to ESIMs operating with nongeostationary FSS satellites.  47 CFR § 2.106 footnotes 5.484B, 5.527A, NG527A.
  
IV. ORDER (WRC-19 ADMIN ORDER)
10. In this Order, we make several non-substantive, editorial changes to the Commission’s Allocation Table. The Commission’s rules provide the International Table for informational purposes only.  47 CFR § 2.104(a).  To ensure that we timely and efficiently reflect WRC decisions affecting the International Table, we typically first issue an order, as appropriate, to reflect such updates and to address administrative changes within the U.S. Allocation Table.  Substantive changes to the U.S. Table require additional review and coordination between NTIA and FCC and are therefore addressed through a subsequent notice and comment rulemaking proceeding.  We develop proposals in that subsequent proceeding to harmonize our spectrum allocations with and conform our rules to the International Table to the extent that doing so would better meet domestic allocation requirements.
  None of the rule changes discussed in this order are subject to the notice and comment requirements for rulemaking in the Administrative Procedure Act (APA). See 5 U.S.C. § 553 (herein referred to as the “APA”), and in particular, 5 U.S.C. § 553(b)(B) (allowing for implementation without notice and comment or publication in the Federal Register if good cause exists).
  Section 553(b)(B) of the APA provides exceptions to the notice and comment requirements for rulemakings when, among other things, the agency finds good cause that the notice and comment requirements are “impracticable, unnecessary, or contrary to the public interest” with respect to the rules at issue.  Specifically, in this Order, we make conforming changes to and correct minor errors in the Allocation Table, including removing expired text from domestic footnotes.  All of these changes are summarized below.  These changes have no substantive effect on industry or the general public.  Accordingly, we find that it is “unnecessary,” within the meaning of section 553(b)(B) of the APA, to provide notice and an opportunity for public comment before adopting these rule revisions.
A. Reflecting WRC-19 Revisions in the International Table
11. We update the International Table within section 2.106 of the Commission’s rules to reflect Article 5, section IV of the Radio Regulations (Edition of 2020), except as revised herein. Specifically, we reflect WRC-19’s allocation actions by revising the International Table (by updating the radio service entries and the references to international footnotes in the Region 1, Region 2, and Region 3 Tables) and the list of International Footnotes (by adding 35 international footnotes, revising 127 existing international footnotes, and removing seven international footnotes).  The International Table within section 2.106 of the rules is included for informational purposes only, and thus, the changes that we make are non-substantive, editorial actions.  47 CFR § 2.104(a).  Any minor, editorial differences between the ITU Radio Regulations and the International Table in section 2.106 of the Commission’s rules that are discussed in this Order will also be listed in the FCC Online Table of Frequency Allocations, http://www.fcc.gov/oet/spectrum/table/fcctable.pdf.  We note that Title 47 of the Code of Federal Regulations (CFR) contains the official version of the Table of Frequency Allocations and the FCC Online Table of Frequency Allocations is provided for convenience only.  The official version of Title 47 CFR is available at https://www.ecfr.gov/current/title-47.
  The International Table is included within the Commission’s Allocation Table for informational purposes only. 47 CFR § 2.104(a).
  Consistent with past practice, See, e.g., Amendment of Parts 1, 2, 15, 25, 73, and 90 of the Commission’s Rules to Make Non-Substantive Editorial Revisions to the Table of Frequency Allocations and to Various Other Rules, Order, 25 FCC Rcd 9712, 9721, para. 17 (OET and OMD 2010) (stating that “we will not replicate typographical or other errors (in the version of the International Table displayed in section 2.106) that hold the potential to cause reader confusion or convey misleading information.”).
 we incorporate the following corrections and updates to the ITU’s Table of Frequency Allocations for display as the International Table in section 2.106 of the Commission’s rules:  First, we update eight footnotes (5.328B, 5.341A, 5.341B, 5.341C, 5.351A, 5.384A, 5.388, 5.484B) by cross referencing four resolutions (Resolutions 155, 212, 223, 610) that were revised at WRC-19.  Next, we: 1) revise two footnotes (5.169A, 5.169B) to make them consistent with the Federal Register’s style used in footnote 5.346 and update the cross reference to Resolution 99 in footnote 5.346 to match the version shown in footnotes 5.169A and 5.169B; and 2) correct footnotes 5.547 and 5.550E by adding the missing notation “Rev.” and by removing a dash that is inconsistent with 72 other instances of “non-geostationary-satellite systems” in Volume 1 of the Radio Regulations, respectively. We are in the process of revising the Allocation Table to comport with Federal Register codification formatting requirements.  See Amendment of the Commission’s Rules to Make Non-Substantive Editorial Revisions to Part 2, ET Docket No. 23-108,  Order (2023).  To conform to the rules and policies of the Office of the Federal Register, we will no longer use the ITU’s notational system, which signifies which world radiocommunication conference adopted or revised an international footnote, in the Commission’s list of international footnotes.  Nor will we append the notation “(FCC)” to signify that we are revising (simplifying) the text of an international footnote in section 2.106.  We will continue to maintain a list of discrepancies in note 1 of the FCC Online Table.  We are maintaining previous cross reference updates for six resolutions (Resolutions 75, 222, 225, 413, 517, 716) in six footnotes (5.197A, 5.351A, 5.353A, 5.389A, 5.389C, 5.547) that WRC-19 did not update.  We note that while footnote 5.357A contains the correct cross reference to Resolution 222, i.e., “(Rev.WRC12),” the Radio Regulations still include a note by the Secretariat stating that this resolution was revised by WRC-07 and WRC-12.  ITU Radio Regulations, Vol. 1, Article 5, footnote 5.357A, Note by the Secretariat, at 104. 
   Finally, we note that WRC-19 revised footnote 5.79 by permitting the use of the NAVDAT [navigational data] system to expand the potential uses of the band.  Because this is not a non-substantive editorial change to the International Table that affects the U.S. Table, we maintain the status quo of the U.S. Table by replacing the existing reference to footnote 5.79 in the 415-472 kHz, 479-495 kHz, and 505-510 kHz bands within the U.S. Table with that of placeholder footnote US79A.  Footnote US79A contains the pre-WRC-19 text of footnote 5.79, except that we list only the bands where footnote 5.79 currently applies (i.e., we exclude the 472-479 kHz band, which is no longer allocated to the maritime mobile service, and the 510-525 kHz band, to which we have never applied the provisions of footnote 5.79).  We further note that revised footnote 5.79 applies to the maritime mobile service in the 415495 kHz and 505-526.5 kHz bands in all ITU Regions; however, a reference to footnote 5.79 is not shown in the 510-525 kHz band within the Region 2 Table and there is no maritime mobile service entry or reference to footnote 5.79 in the 525-526.5 kHz sub-band within the Region 2 Table of the Radio Regulations. ITU Radio Regulations, Vol. 1, Article 5, at 48.
  Therefore, we add this footnote 5.79 issue to note 1 of the Online Table. Commission staff will revise note 1 of the FCC Online Table to read as follows:  The International Table (columns 1-3 of § 2.106) reflects Article 5, section IV of the ITU Radio Regulations (Edition of 2020), except for certain style/notational/accounting differences (e.g., suppressed footnotes, footnote numbers that are not used, bolded text, a historical note, and a space between the third and fourth digits are not shown), minor corrections (i.e., the deletion of an unneeded note by the Secretariat and an unneeded dash in footnotes 5.357A and 5.550E, respectively), and the note and revisions listed below:
Band; TableRemarks510-525 kHz; Region 2Footnote 5.79 is missing in the bands 510-525 kHz and 525526.5 kHz and “MARITIME MOBILE” is not shown in the band 525526.5 kHz.525-526.5 kHz; Region 2International FootnoteAction5.169A, 5.169B, 5.346Deleted the first star, replaced the second star with “Note:” and updated Resolution 99 from “(Rev. Busan, 2014)” to “(Rev. Dubai, 2018)” in 5.346.5.197A, 5.328B, 5.341A, 5.341B, 5.341C, 5.351A, 5.353A, 5.384A, 5.388, 5.389A, 5.389C, 5.484B, 5.547The cross-references to ITU Resolutions 75, 155, 212, 222, 223, 225, 413, 608, 610, and 716 have been updated to reflect the versions shown in Volume 3 of the ITU Radio Regulations (Edition of 2020).

B. Reflecting WRC-19 Revisions in the U.S. Table
12. WRC-19 deleted one international footnote (5.396) that is referenced in the U.S. Table and revised a resolution that is referenced in two domestic footnotes (US444B, G132).  We reviewed the relevant footnotes (5.396, US444B, G132) and find that implementing these changes in the Commission’s rules will have no substantive effect on nonFederal operations.
13. Footnote 5.396 requires space stations in the broadcasting-satellite service (BSS) in the band 2310-2360 MHz operating in accordance with footnote 5.393 that may affect the services to which this band is allocated in other countries to be coordinated and notified in accordance with Resolution 33 (Rev.WRC-15), and further provides that complementary terrestrial broadcasting stations shall be subject to bilateral coordination with neighboring countries prior to their bringing into use.  WRC-19 deleted Resolution 33 because the processing of filings under this Resolution was completed prior to WRC07, and consequently deleted footnote 5.396 after moving its still-relevant text to footnote 5.393. See CPM Report to WRC-15, supra note 9, Annex 6/4-1, page 838.  WRC-19 edited footnote 5.393 by including the last sentence in deleted footnote 5.396 (“Complementary terrestrial broadcasting stations shall be subject to bilateral coordination with [neighboring] countries prior to their bringing into use.”).  See ITU Radio Regulations, Vo1. 1, Article 5, footnote 5.393, at 115.
  We are updating footnote 5.393 in the International Footnotes to reflect the WRC-19 revisions.  See Appendix A.  In the United States, BSS operators provide satellite radio service to customers using the 2320-2345 MHz band and footnote 5.393 is not included in the 2310-2360 MHz band of the U.S. Table.  We therefore find that removal of footnote 5.396 will have no substantive effect on non-Federal operations.  We find that the reference to footnote 5.396 should be removed from the nonFederal Table, consistent with the WRC-19 implementation. 
14. Footnote US444B contains a cross reference to Resolution 418 (Rev.WRC-12). In pertinent part, footnote US444B states that, in the 5091-5150 MHz band, use of the primary aeronautical mobile service allocation by aeronautical telemetry transmissions from aircraft stations (AMT) must be in accordance with Resolution 418 (Rev.WRC-12).  47 CFR § 2.106 footnote US444B.
  WRC-19 revised Resolution 418 by updating the guidance on the aeronautical mobile service use of the 5091-5150 MHz band by citing to Resolution 748 (Rev.WRC-19), by deleting the invitation that the ITU continue to study the conditions and arrangements for flight testing in this band, and by simplifying its text.  Therefore, we find that changing the reference to WRC-19’s revision of Resolution 418 will not have any substantive effect on nonFederal operations.
15. We update footnote G132, which applies to the 1215-1240 MHz band, to cross reference revised Resolution 608, replacing “(Rev.WRC-15)” with “(Rev.WRC-19).” 47 CFR § 2.106 footnote G132.
  Resolution 608 pertains to the protection of the radionavigation service in certain countries in Regions 1 and 3; because the United States is located in Region 2 , the revision of this resolution will not have any substantive effect on nonFederal operations.
C. Other Revisions to the Allocation Table
16. In this section, we make the following additional editorial changes to section 2.106 of the Commission’s rules:
• Correct the Federal and non-Federal Tables by removing the reference to footnote 5.79A from the 435-472 kHz band because the footnote does not apply to that band.
• Revise footnotes US1, US82, US247, US281, US283, US296, US342, and G115 by changing the references to frequency units from “kHz” to “MHz” and revise footnote G32 from “MHz” to “GHz” in order to make the text of the footnotes consistent with the frequency units shown in the Allocation Table. In each of these footnotes, we also move the decimal point three spaces to the left and delete unneeded zeros.  In footnote US342, we also correct a typographical error by changing from “23.07-23.12 GHz” to “23.07-23.12 GHz.”

• Add a space between the third and fourth digits of frequency bands that contain five digits in 28 international footnotes. Specifically, we make this display change by revising footnotes 5.109, 5.110, 5.111, 5.132, 5.133A, 5.134, 5.145, 5.145B, 5.146, 5.147, 5.149, 5.149A, 5.150, 5.151, 5.152, 5.153, 5.154, 5.155, 5.155A, 5.155B, 5.156, 5.156A, 5.157, 5.158, 5.474D, 5.477, 5.478, and 5.479.  This display change is based on the format used in the Radio Regulations.  ITU Radio Regulations, Vol. 1, Article 5, at 35-186.  

• Simplify the display of facing pages in the Allocation Table. The heading on the top page of Allocation Table also applies to the bottom page, i.e., every two pages in the Allocation Table are facing pages.  We simplify the display of facing pages in the Allocation Table by ending page 19 on the frequency 52 MHz in the Region 1 Table and on the frequency 54 MHz in all other tables (instead of permitting the entries for the 5054 MHz band in the combined table for Regions 2 and 3 and the non-Federal Table, and the 50-73 MHz band in the Federal Table, to span pages 19 and 20).

• Remove the references to footnote US108 from the 3300-3500 and 3500-3550 MHz bands in the Federal Table and from the 3300-3450 and 3450-3600 MHz bands in the non-Federal Table and revise footnote G2 by deleting “(except as provided for in US108)” because footnote US108 no longer applies to the 33003550 MHz band. Footnote US108 was recently revised to remove the text that applied to the 3300-3550 MHz band.  Facilitating Shared Use in the 3100-3550 MHz Band, WT Docket No. 19-348, Second Report and Order, Order on Reconsideration, and Order of Proposed Modification, 36 FCC Rcd 5987, 6057, 6060 (2021); 47 CFR § 2.106 footnote US108.
  Also move the reference to footnote US431B from the bottom of the cell to the right of RADIOLOCATION in the 3300-3500 MHz band within the Federal Table because the footnote applies to only the radiolocation service.  
• Place footnotes US431B and US433 in ascending numerical order in the 3450-3600 MHz band within the non-Federal Table.  On page 39 of the Allocation Table, change the frequency range of the facing pages from “2483.5-3500” to “2483.5-3600” because 3450-3600 MHz is the last frequency band in the non-Federal Table in this set of facing pages.
• Simplify the non-Federal Table by combining the common radiocommunication service entries in the 3600-3650 MHz and 3650-3700 MHz bands to form the 36003700 MHz band, move the text of footnote NG185 to footnote NG169, and remove footnote NG185 from the list of non-Federal government (non-Federal) footnotes.
• Simplify the Federal Table by combining the common radiocommunication service entries in the 17.8-18.3 GHz and 18.3-18.6 GHz bands to form the 17.8-18.6 GHz band.
• Correct the placement of footnote NG65 in the 24.75-25.25 GHz and 47.2-48.2 GHz bands by moving the footnote reference from the right of the fixed-satellite service (Earth-to-space) entry to the bottom of the cell because this footnote refers to three allocated services. For consistency in the Allocation Table, we employ the following rules for footnote placement in both the International and U.S. Tables:  The footnote references that appear below the allocated service or services apply to more than one of the allocated services, or to the whole of the allocation concerned.  The footnote references that appear to the right of the name of a service are applicable only to that particular service.  47 CFR § 2.104(h)(5)-(6).
 
• Correct footnotes 5.430A, 5.458, 5.509D, and 5.547 to reflect their text as shown in the Radio Regulations. ITU Radio Regulations, Vol. 1, Article 5, at 122, 132, 150, and 164.  Specifically, we correct footnotes:  1) 5.430A by deleting the last sentence (i.e., “This allocation is effective from 17 November 2010.”); 2) 5.458 by changing from “6425-7025 MHz” to “64257075 MHz” in the last sentence; 3) 5.509D by changing from “19000” to “19 000” in the last sentence; and 4) 5.547 by changing from “Resolution 75 (WRC-12)” to “Resolution 75 (Rev.WRC-12).”

• Revise footnote US52 to account for now-expired text.  Footnote US52 states that use of the frequencies 156.775 MHz and 156.825 MHz by the mobilesatellite service (Earth-to-space) is restricted to the reception of long-range Automatic Identification System (AIS) broadcast messages from ships.  It also provided, in the text of the footnote, for port operations and ship navigation communications on these two frequencies (AIS 3 and AIS 4) until August 26, 2019. 47 CFR § 2.106 footnote US52 paragraph (b).
  We revise footnote US52 paragraph (b) to remove the reference to August 26, 2019.  Previous port operations and ship navigation communications on these two frequencies (AIS 3 and AIS 4) expired on August 26, 2019 and are no longer permitted. Recommendation ITU-R M.1371-5 (02-2014) designates channels 75 and 76, otherwise known as AIS 3 and AIS 4, for Long Range Detection of AIS, Earth-to-space.  Recommendation ITU-R M.1371-5 (02-2014), 49, § 4.1.1, 65-67, § 3, Annex 4.  This change was made due to excessive channel loading on AIS 1 and AIS 2 that made ship detection by satellite extremely difficult and could result in a potential safety hazard.
 
• Revise footnotes US100, 47 CFR § 2.106 footnote US100.  Specifically, we update footnote US100 by removing the expired text in paragraph (b) providing that the 2345-2360 MHz band would be available for non-Federal aeronautical telemetering and associated telecommand operations for flight testing of aircraft and missiles until January 1, 2020.
 US312, 47 CFR § 2.106 footnote US312.  Specifically, we update footnote US312 by limiting the use of the frequency 173.075 MHz by all stolen vehicle recovery systems to an authorized bandwidth not to exceed 12.5 kilohertz and striking language regarding operations on 20 kilohertz that expired on May 27, 2019.
 and NG33 47 CFR § 2.106 footnote NG33.  Specifically, we update footnote NG33 by removing the expired text in paragraph (a), i.e., the transition period for full-power and Class A television (TV) station and fixed TV broadcast auxiliary station operations in the 614-698 MHz band has concluded and the band is now used predominately for mobile broadband services.  We also correct a typographical error, i.e., white space devices may operate in the 657663 MHz band in accordance with section 15.707(a)(2), instead of paragraph (a)(4), and we simplify the text of the footnote.  47 CFR § 15.707(a)(2).
 to remove footnote text that pertains to dates that have passed (i.e. expired text).
V. NOTICE OF PROPOSED RULEMAKING (WRC-15 NOTICE)
17. In this Notice of Proposed Rulemaking (WRC-15 Notice), we propose to:  1) implement certain WRC-15 allocation decisions not previously addressed; 2) make other allocation changes that are not related to WRC-15 implementation;  The proposals that are not related to WRC-15 implementation are: 1) restricting the use of the mobile-satellite service (Earth-to-space) in the frequency bands designated for use by the Automatic Identification System (AIS 1-4) to non-Federal space station reception of AIS messages; 2) deleting the broadcasting service allocation from the 700 MHz band; 3) updating the rules to recognize that the transition period for the reallocation of the 18.319.3 GHz band from the fixed service to the fixed-satellite service (space-to-Earth) has concluded; and 4) removing eight inactive call signs from footnote NG62.
 and 3) revise parts 2, 25, 74, 78, 90, 97, and 101 of the rules to reflect the allocation changes that we are proposing in this Notice.  We first address satellite allocation issues in seven sections, and then we address terrestrial allocation issues in five sections.
A. Satellite Issues
1. Protection of Search and Rescue Satellites Receiving in the 406406.1 MHz Band
18. We propose to adopt new footnote US265 for the 403-410 MHz band to protect satellitebased search and rescue systems Our rules authorize Emergency Position-Indicating Radio Beacon, Emergency Locator Transmitter, and Personal Locator Beacon transmissions to Federal government satellites that carry Search and Rescue Satellite (SARSAT) receivers.  The National Oceanic and Atmospheric Administration (NOAA) operates polar orbiting and geostationary satellites that carry payloads providing distress alert and location information to appropriate public safety rescue authorities for maritime, aviation, and land users in distress.  47 CFR §§ 80.209(a)(7), 80.905(a)(3)(vi), (a)(4)(vi), 80.1077, 80.1129(c), 87.139(h), 87.147(e), 87.173(b), 87.187(m), 87.195(a), 87.199, 95.2963, and 95.2971.  NTIA WRC-15 Implementation Recommendations, Attachment 1 – Annex 9.1.1, 83-86.
 operating in the 406-406.1 MHz band from outofband emissions originating from operations in adjacent bands, as provided in Resolution 205 (Rev.WRC-19). In the companion WRC-19 Order, footnote 5.265 is revised to cross reference Resolution 205 (Rev.WRC19), i.e., WRC-19 added noting d), which states “that Report ITU-R SM.1051 provides a methodology to monitor the electromagnetic environment in the adjacent frequency bands 405.9-406 MHz and 406.1-406.2 MHz).”  ITU Radio Regulations, Vol. 3, p. 225, Resolution 205 (Rev.WRC-19), noting d).  Footnote 5.267 states that any emission capable of causing harmful interference to the authorized uses of the 406406.1 MHz band is prohibited.  47 CFR § 2.106 footnote 5.267.  
  Proposed US265 would prohibit new frequency assignments Assignment (of a radio frequency or radio frequency channel) is defined as an authorization given by an administration for a radio station to use a radio frequency or radio frequency channel under specified conditions. 47 CFR § 2.1(c).  In general, the assignment of frequencies and frequency bands must be in accordance with the  Allocation Table.  47 CFR § 2.102(a).  The radio frequency devices authorized pursuant to 47 CFR part 15 are not based on allocated radio services.  47 CFR § 2.105(e) note 1.  The term, short-range radiocommunication devices, is intended to cover radio transmitters that have low capability of causing interference to other radio equipment.  In general, such devices are permitted to operate on a non-interference, no protection from interference basis.  Simple licensing requirements may be applied, e.g. general licenses or general frequency assignments or even license exemption.  See Recommendation ITU-R SM.1538-1, Annex 1, p. 2 at 2 (Definition of short-range radiocommunication devices).  Medical Device Radio Communications (MedRadio) devices, similar to part 15 devices, are short-range devices.
 within the 405.9406.0 MHz and 406.1406.2 MHz bands under the mobile and fixed services allocations. In Resolution 205, WRC-15 (and later WRC-19) resolved to “to request administrations not to make new frequency assignments within the frequency bands 405.9-406.0 MHz and 406.1-406.2 MHz under the mobile and fixed services.”  Id. at resolves 1.
  For radiosonde applicants that seek to operate in this band, proposed US265 would require that the frequency drift characteristics of radiosondes be taken into account when selecting operating frequencies above 405 MHz to avoid transmitting in the 406406.1 MHz band and that all practical steps be taken to avoid the operating frequency drifting close to 406 MHz. The 403-406 MHz band is a Federal/non-Federal shared band that is allocated to the meteorological aids service (radiosonde) on a primary basis.  The Commission licenses radiosondes under its part 5 experimental radio service; however, there are currently no active licenses for non-Federal radiosonde use of the 403-406 MHz band.  47 CFR part 5.
  This proposed footnote seeks to address concerns that aggregate levels of electromagnetic interference, including interference from transmissions in adjacent frequency bands, may present a risk of satellite emergency transmissions being undetected, or delayed in reception, or lead to reduced accuracy of the calculated locations.  We seek comment on this proposal.
19. Currently, non-Federal use of the fixed and mobile services in the adjacent 403-406 MHz and 406.1-410 MHz bands is permitted pursuant to footnotes US13, US55, and US64. 47 CFR § 2.106 footnotes US13, US55, and US64.
  Footnote US64 states, inter alia, that the 403-406 MHz band is allocated to the mobile except aeronautical mobile service on a secondary basis and that nonFederal use is limited to medical device radiocommunication service (MedRadio) operations. 47 CFR § 2.106, US64(a).  
  MedRadio is an ultralow power radio service that is associated with medical implant devices and medical body-worn devices.  MedRadio stations are licensed-by-rule and operate in accordance with part 95, subpart I of the rules,  so the Commission does not issue individual station licenses for MedRadio devices. See 47 CFR §§ 95.2505 (MedRadio is defined as an ultra-low power radio service), 95.2567 (radiated power limited to a maximum of 25 microwatts M-EIRP, 95.2503 [MedRadio equivalent isotropically radiated power]).  “Licensed-by-rule” means that an authorized user can access the entire available spectrum without an individual station license document and is instead authorized to operate as long as the operations are in accordance with the applicable service rules.  See 47 U.S.C. § 307(e).  Thus, while all spectrum use is shared among users who meet the eligibility and technical qualifications and no one has exclusive rights to any portion of the spectrum, those users are collectively afforded interference protection vis-à-vis other services, based on the allocation status under which they operate.
  Hence, we tentatively conclude that continued operations of MedRadio devices are consistent with proposed US265.  We seek comment on this tentative conclusion.
20. Footnote US13 and section 90.265 of the Commission’s rules make 48 channels available for transmitting hydrological and meteorological data (Hydro channels), including channels with center frequencies 406.125 MHz and 406.175 MHz. 47 CFR §§ 2.106 footnote US13, 90.265(a), (a)(8).
  We propose to revise footnote US13 and section 90.265 to state that, after the effective date of final rules in this proceeding, no assignments for the frequencies 406.1250 MHz and 406.1750 MHz will be made, and that existing stations may continue to operate indefinitely on these frequencies as they are currently licensed. As of April 18, 2023, 63 licenses in the Commission’s Universal Licensing System authorized operation in the 406.125406.175 MHz band.  This Notice does not modify those licenses.
  See Appendix B.  By no longer issuing licenses for the frequencies 406.1250 MHz and 406.1750 MHz, we would ensure consistency with proposed new footnote US265 and protect satellitebased search and rescue systems operating in the adjacent 406-406.1 MHz band from outofband emissions originating on those frequencies.  We seek comment on these proposals.
21. Footnote US55 provides that the Commission may authorize public safety use of 40 Federal Interoperability Channels that are designated in section 4.3.16 of the NTIA Manual.  However, because section 4.3.16 of the NTIA Manual does not include frequencies within the 406.1406.2 MHz sub-band, it is not necessary to amend the language of this footnote. See National Telecommunications and Information Administration’s Manual of Regulations and Procedures for Federal Radio Frequency Management (NTIA Manual), 2021 Edition, section 4.3.16, at pages 4-280 and 4-281.
  Finally, we propose to update footnote US117 to properly reflect that non-Federal use of the 406.1-410 MHz band is limited to the radio astronomy service and as provided by footnotes US13 and US55, as shown in Appendix B. This proposed revision of US117 was overlooked when the Commission originally adopted US55.
  We seek comment on these proposals, including any estimates of the costs and benefits of implementation.
2. Space Research Service (space-to-space) in the 410420 MHz Band
22. We propose to allocate the 410-420 MHz band to the space research service (space-to-space) on a secondary basis for non-Federal use, and to adopt footnote 5.268, which would limit use of this allocation to communication links with an orbiting, manned space vehicle and require compliance with a power flux-density limit at the Earth’s surface to protect existing and future licensees. Footnote 5.268 limits the power flux-density (PFD) at the surface of the Earth to maximum specified values        (–153 to –148 dBW/m² in a 4 kilohertz bandwidth) depending on the angle of arrival and prohibits stations in the space research service from claiming protection from, or constraining the use and development of, stations of the fixed and mobile services.  47 CFR § 2.106 footnote 5.268.
  The 410420 MHz band is currently allocated to the fixed, mobile, and space research (spaceto-space) services on a primary basis for Federal use; the 413-419 MHz segment is allocated to the mobile, except aeronautical mobile, service on a secondary basis, with non-Federal use limited to part 95 MedRadio operations. 47 CFR § 2.106, US64(b); see supra note 50.
  The National Aeronautics and Space Administration (NASA) operates systems in support of extra-vehicular activity communications for the manned space program and other space related efforts in this band. NTIA’s “Federal Government Spectrum Use Reports 225 MHz – 7.125 GHz,” 410-420 MHz, at 13 no. 4c. (last visited Feb. 28, 2022).
  The systems are used for communications between crew members and for relaying telemetry data to the main spacecraft.  NonFederal use is limited to MedRadio operations, hydrological/meteorological data, and public safety. 47 CFR § 2.106 footnotes US13, US55, US64(b).
  We expect that the additional non-Federal use would be similar to the current Federal uses and would occur because of increasing space exploration by private companies.  We request comment on these proposals, including information on the costs and benefits. NTIA recommends we adopt this proposal.  NTIA WRC-15 Implementation Recommendations, Attachment 1 – Annex 1.13, 66.

3. Global Flight Tracking for Civil Aviation (1087.7-1092.3 MHz)
23. We propose to allocate the 1087.7-1092.3 MHz band to the aeronautical mobilesatellite (route) service (Earth-to-space) on a primary basis, limited to space station reception of automatic dependent surveillance-broadcast (ADSB) emissions from aircraft.  If adopted, we would implement this proposed allocation by referencing footnote 5.328AA in the 960-1164 MHz band within the U.S. Table. Footnote 5.328AA states that:  1) stations must operate in accordance with recognized international aeronautical standards; 2) stations in the aeronautical mobilesatellite (route) service operating in the band shall not claim protection from stations operating in the aeronautical radionavigation service; and 3) Resolution 425 (WRC-15) shall apply).  47 CFR § 2.106 footnote 5.328AA.  In the companion WRC-19 Order, we update footnote 5.328AA by cross referencing the current version of Resolution 425, i.e., “(Rev.WRC-19)” instead of the superseded version, i.e., “(Rev.WRC-15).”  See also NTIA WRC-15 Implementation Recommendations, Attachment 1 – Annex GFT/IFF, 104, and Attachment 2 – US128, 107; and ITU Radio Regulations, Resolution 425 (WRC-15), at 281-282.
  The 9601164 MHz band is currently allocated to the aeronautical mobile (route) and aeronautical radionavigation services on a primary basis for Federal and non-Federal use. 47 CFR § 2.106.  Under footnote 5.327A, use of the aeronautical mobile (route) service allocation is limited to systems that operate in accordance with recognized international aeronautical standards and in accordance with Resolution 417 (Rev.WRC-15).  Under footnote 5.328, use of the 960-1215 MHz band by the aeronautical radionavigation service is reserved on a worldwide basis for the operation and development of airborne electronic aids to air navigation and any directly associated ground-based facilities.  Under footnote US224, Federal systems utilizing spread spectrum techniques for terrestrial communication, navigation, and identification may be authorized to operate in the 9601215 MHz band on the condition that harmful interference will not be caused to the aeronautical radionavigation service.  Id. footnotes 5.327A, 5.328, US224.
  Aircraft currently transmit ADS-B signals to report their position to ground-based receivers in a 4.6megahertz wide band centered on 1090 MHz under the existing aeronautical mobile (route) service allocation. 47 CFR § 2.106.
  This proposed allocation would extend reception of ADSB signals beyond terrestrial lineof-sight to facilitate reporting the position of aircraft located anywhere in the world. Supra note 61, Resolution 425 (WRC-15) at considering g).  On June 6, 2019, we proposed in WT Docket No. 19-140 to establish rules specifically for airborne ADS-B transmissions on 1090 MHz.  Amendment of the Commission’s Rules to Promote Aviation Safety, WT Docket No. 19-140, Notice of Proposed Rulemaking, 34 FCC Rcd 4984, 4991-93, paras. 22-24 (2019) (Aviation Safety NPRM).
   We tentatively conclude that providing for satellite reception of ADS-B signals would ensure the efficient management of air traffic in oceanic, polar, and remote airspace. See generally, CITEL Proposals to WRC-15, agenda item GFT(PP-14), Addendum 25 to Document 7-E, dated August 21, 2015 (Doc. 4000-GFT.doc), p. 5 (Reasons for proposed footnote).
  Further, we tentatively conclude that this proposed allocation would support the Federal Aviation Administration’s rules regarding aircraft location information. Aviation Safety NPRM, 34 FCC Rcd 4991-92, para. 22.
  We also propose to add new paragraph (a)(13) to section 25.202 of the Commission’s rules to permit the licensing of space stations that can receive ADS-B emissions from aircraft. See Appx. B.
  We seek comment on these proposals.
24. Further, as recommended by NTIA, we propose to add new footnote US78 to the 960-1164 MHz band to recognize Federal use by military Identification Friend or Foe (IFF) systems on center frequencies 1030/1090 MHz.  We propose this use would be subject to the condition that harmful interference would not be caused to the aeronautical radionavigation service or the aeronautical mobile (R) service. Specifically, NTIA recommends a footnote (which we propose as US78) stating that military systems used for Identification Friend or Foe (IFF) operations are authorized to operate on the center frequencies 1030 MHz for interrogators and 1090 MHz for transponders on the condition that harmful interference would not be caused to the aeronautical radionavigation service or the aeronautical mobile (route) service.  Supra note 61.
  Finally, we propose to revise footnote US224 to require that Federal systems utilizing spread spectrum techniques for terrestrial communication, navigation, and identification in the 960-1215 MHz band be authorized on the condition that harmful interference not be caused to the aeronautical mobile (R) and aeronautical radionavigation services in the 960-1164 MHz band, military IFF systems on center frequencies 1030/1090 MHz, aeronautical mobile-satellite (R) service (Earthtospace) in the 1087.7-1092.3 MHz band, and the aeronautical radionavigation and radionavigation-satellite (space-to-Earth) (space-to-space) services in the 1164-1215 MHz band.  We request comment on these proposals, including whether any modifications to the part 87 rules for aviation services would be necessary to implement our proposals.
4. Satellite Uplinks in the 7190-7250 MHz Band
25. As recommended by NTIA, we seek comment on whether to provide additional spectrum on a secondary basis for non-Federal Earthtospace operations in the Earth explorationsatellite service in the 7190-7250 MHz band and space research service in the 7190-7235 MHz band. NTIA WRC-15 Implementation Recommendations, Attachment 1 – Annex 1.11, 56-60.
  In the U.S. Table, the 7190-7250 MHz band is allocated to the Earth exploration-satellite (Earth-to-space) and fixed services, both on a primary basis and exclusively for Federal use. As requested by NTIA, in the WRC-15 Admin Order, we added a primary allocation for the Federal Earth exploration-satellite service (EESS) (Earth-to-space) in the 7190-7250 MHz band and two international footnotes (5.460A, 5.460B) that limit the use of this EESS uplink allocation.  Footnote 5.460A limits the EESS uplink allocation to tracking, telemetry, and command for the operation of spacecraft, and, e.g., specifies that space stations operating under this allocation in the 7190-7250 MHz band may not claim protection from stations in the fixed and mobile services.  Footnote 5.460B states that EESS geostationary satellites receiving in the 7190-7235 MHz band may not claim protection from existing and future stations of the space research service.  We also replaced footnote G133 with the essentially identical international footnote 5.460.  WRC-15 Admin Order, supra note 3, para. 10.  47 CFR § 2.106 footnotes 5.458 (passive measurements), 5.460A, 5.460B, G134 (up to five earth stations in the meteorological-satellite service (Earth-to-space) may be authorized).
  The 7190-7235 MHz portion of the band is also allocated on a primary basis to the space research service (Earth-to-space) exclusively for Federal use.  
26. Consistent with NTIA’s recommendation, should we make these Federal uplink bands available for non-Federal use on a secondary basis for Earth-to-space operations in the Earth exploration-satellite and space research services, respectively, by adding footnotes US460 and US460A to the 71907235 MHz band and footnote US460A to the 7235-7250 MHz band?  Footnote US460 would provide a secondary non-Federal allocation in the 7190-7235 MHz band for the space research service (Earth-to-space) and would prohibit emissions from such systems intended for deep space.  Footnote US460A would allocate the 71907250 MHz band to the Earth exploration-satellite service (Earth-to-space) on a secondary basis for nonFederal use, limited to tracking, telemetry, and command (TT&C) for the operation of spacecraft. The restrictions in footnotes US460 and US460A are based on footnotes 5.460 and 5.460A.
  In both cases, should we explicitly require that authorizations be subject to a case-by-case electromagnetic compatibility (EMC) analysis and approval? Appx. B, footnotes US460 and US460A (proposed text).
  Qualcomm urges the Commission to seek comment on whether such allocations would “remain in line with the Commission’s present spectrum priorities,” noting that the Chairwoman has identified the 7-15 GHz spectrum range, and  some stakeholders, other administrations, and regional organizations are considering the 7190-7250 MHz band, for the next generation wireless technology. Letter from Aspasia A. Paroutsas, Vice President, Federal Regulatory Affairs, Qualcomm, to Marlene Dortch, Secretary, FCC, ET Docket Nos. 23-121 and 23-120, RM-11785, at 2 (filed April 12, 2023) (Qualcomm Ex Parte).  
  We request comment on these recommendations.
5. Earth Exploration-Satellite Service (Active) in the 9.2-9.3 GHz and 9.910.4 GHz Bands
27. We seek comment on allocating the 9.2-9.3 GHz and 9.9-10.4 GHz bands to the Earth exploration-satellite service (active) on a primary basis for Federal use and on a secondary basis for nonFederal use, subject to four footnotes:  5.474A, 5.474B, 5.474C, and US474D. Footnote US474D is based on the text in international footnote 5.474D, except that we do not include the radiolocation service in the 9.2-9.3 GHz band because this allocation has secondary status in both the Federal and non-Federal Tables, and we do not include the radionavigation service in the 9.9-10 GHz band because that allocation only applies in the countries listed in footnote 5.478.  Appx. B (US474D); 47 CFR § 2.106 footnotes 5.474A, 5.474B, 5.474C, 5.474D; and NTIA WRC15 Implementation Recommendations, Attachment 1 – Annex 1.12, 6163.
  This would implement WRC-15’s expansion of the current worldwide Earth exploration-satellite service (active) allocation in the 9.3-9.9 GHz band by allocating 600 megahertz of additional spectrum in the adjacent bands to this service, which would support the growing demand for greater radar image resolution to satisfy global environmental monitoring requirements. WRC-15 added a primary Earth exploration-satellite service (active) allocation in the 9.2-9.3 GHz, 9.910.0 GHz, and 10-10.4 GHz bands for all Regions in the ITU Allocation Table, adjacent to the existing Earth exploration-satellite service (active) allocations at 9.3-9.8 GHz (primary) and 9.8-9.9 GHz (secondary).  See WRC-15 Final Acts at 37 and 39.
  Spaceborne radars operating in this band support a large number of scientific and geoinformation applications, such as disaster relief and humanitarian aid, land use, and large area coastal surveillance. “For such applications, there is a growing demand for increasing radar image resolution.  Therefore, it is necessary to increase the bandwidth by another 600 MHz for a total of 1200 MHz contiguous bandwidth.”  CITEL Proposals to WRC-15, agenda item 1.12, Addendum 12 to Document 7-E, dated August 21, 2015 (Doc-40001_12.doc) and CPM Report to WRC-15, agenda item 11.2, Chapter 2, p. 21-22, Background.
  We request comment on these potential allocations.
28. In the U.S. Table, the 9.2-9.3 GHz band is allocated to the maritime radionavigation service on a primary basis and to the radiolocation service on a secondary basis for Federal and nonFederal use. These allocations are subject to four footnotes.  47 CFR § 2.106 footnotes 5.472, 5.474, US110, G59.
  The 9.910.5 GHz band is allocated to the radiolocation service on a primary basis for Federal use and on a secondary basis for nonFederal use. The 9.975-10.025 GHz band is also allocated to the meteorological-satellite service on a secondary basis for use by weather radars.  47 CFR § 2.106 footnote 5.479.
  The 10-10.5 GHz and 10.45-10.5 GHz bands are allocated to the amateur and amateur-satellite services on a secondary basis, respectively. Five footnotes apply to the 10-10.5 GHz band.  47 CFR § 2.106 footnotes 5.479, US108, US128, G32, NG50.
  The 2023 World Radiocommunication Conference will consider whether to identify the 10-10.5 GHz for International Mobile Telecommunications (IMT) in ITU Region 2. 
29. The four footnotes we seek comment on adding to the 9.2-9.3 GHz and 9.9-10.4 GHz bands would limit their use to systems in the Earth exploration-satellite service (active) requiring a necessary bandwidth greater than 600 megahertz that cannot be fully accommodated within the 9.39.9 GHz band (5.474A); protect the radio astronomy service in the 10.6-10.7 GHz band from unwanted emissions (5.474B); protect the space research service (space-to-Earth) in the 8.4-8.5 GHz band from unwanted emissions (5.474C); and require that the Earth exploration-satellite service (active) not cause harmful interference to, or claim protection from, the maritime radionavigation service in the 9.29.3 GHz band and the radiolocation service in the 9.9-10.4 GHz band (US474D). 47 CFR § 2.106 footnotes 5.474A, 5.474B, 5.474C, and 5.474D and Appx. B (US474D).  See also Recommendation ITU-R RS.2065-0 (12/2014) and Recommendation ITU-R RS.2066-0 (12/2014).
  Qualcomm urges the Commission to seek comment on whether the proposed allocations would “remain in line with the Commission’s present spectrum priorities,” noting that the Chairwoman has identified the 7-15 GHz spectrum range, and  some stakeholders, other administrations, and regional organizations are considering the 9.2-9.3 GHz and 9.910.4 GHz bands, for the next generation wireless technology. Qualcomm Ex Parte at 2.  
  
30. We also propose to revise footnote US128 to support the Department of Defense’s development of pulsed emission systems in the 10-10.5 GHz band.  Currently, US128 prohibits pulsed emissions in the 1010.5 GHz band, except for weather radars on board meteorological satellites in the 10-10.025 GHz sub-band. 47 CFR § 2.106 footnote US128 (the amateur, the amateur-satellite, and the non-Federal radiolocation services, which shall not cause harmful interference to the Federal radiolocation service, are the only non-Federal services permitted in the 1010.5 GHz band, and the non-Federal radiolocation service is limited to survey operations as specified in footnote US108).
  NTIA states that the Department of Defense requires flexibility for development of pulsed systems in this band to meet future system needs. NTIA WRC-15 Implementation Recommendations, Attachment 2 – US128, at 106; e-mail from Charles Cooper, Associate Administrator, Office of Spectrum Management, NTIA, to Ronald Repasi, Acting Chief, FCC Office of Engineering and Technology, August 8, 2021, attachment at 1.
  We seek comment on all of the proposals in this section.  In addition we request comment on whether the 9.2-9.8 GHz and 9.9-10.4 GHz bands should be allocated to the Earth exploration-satellite service (active) on a primary basis for non-Federal use, so the status of those non-Federal allocations would mirror the status of the Federal Earth exploration-satellite service (active) allocations in those bands.
6. Revision of the 18.142-19.3 GHz, 28.5-29.1 GHz, and 29.25-29.5 GHz Bands 
31. In this section, we make proposals and seek comment on allocation and service rule changes that would clarify the status of grandfathered fixed stations in the 18.3-19.3 GHz band and permit a heavier use of the fixed-satellite service (FSS) in the 18.142-18.3 GHz, 28.529.1 GHz, and 29.25-29.5 GHz bands.
32. First, we propose to amend footnote US139 by stating that, in the 18.3-19.3 GHz band, earth station licensees in the fixed-satellite service (space-to-Earth) may require that licensees of grandfathered stations in the fixed service cease operations, consistent with the provisions in section 101.95 of the Commission’s rules. On August 26, 2022, Commission staff conducted an advanced license search of the Universal Licensing System (ULS) and found 344 active licenses that authorize operations in the 18.3-19.3 GHz band:  182 microwave public safety pool (radio service code MW), 81 microwave industrial/business pool (MG), 66 common carrier fixed point-to-point microwave (CF), eight TV intercity relay (TI), six local television transmission (CT), and one TV studio transmitter link (TS) licenses.
  We make this proposal because, in the 18.3-19.3 GHz band, there is no fixed service allocation and there are no longer any primary grandfathered fixed stations. Specifically, section 101.85 states that fixed service operations in the 18.3-18.58 GHz and 18.5819.3 GHz bands that remain coprimary under the provisions of sections 74.502(c), 74.602(g), 78.18(a)(4), and 101.147(r) will continue to be coprimary with the fixed-satellite service (FSS) until dates that have long since passed, i.e., these transition periods have concluded.  In addition, section 101.95(a), which concerns the sunset provisions for the 18.319.3 GHz band, includes the following:  Once the relocation rules sunset, an FSS licensee may require the incumbent to cease operations, provided that the FSS licensee intends to turn on a system within interference range of the incumbent, as determined by TIA Bulletin 10-F or any standard successor.  FSS licensee notification to the affected FS [fixed service] licensee must be in writing and must provide the incumbent with no less than six months to vacate the spectrum.  After the six-month notice period has expired, the FS licensee must turn its license back into the Commission, unless the parties have entered into an agreement that allows the FS licensee to continue to operate on a mutually agreed upon basis.  47 CFR §§ 101.85(b)(1)-(2), 101.95(a).
 Consequently, we also propose to revise sections 74.502(c), 74.602(g), 78.18(a)(4), and 101.147(r) of the rules in order to update the introductory text and the frequencies that are available to applicants of aural broadcast auxiliary stations, television broadcast auxiliary stations, cable television relay service, and fixed microwave services, respectively.  These proposals are consistent with the Commission’s previous decision concerning the re-channelization of the 17.7-18.3 GHz and 19.3-19.7 GHz bands for fixed microwave services under part 101 of the rules. In 2006, the Commission adopted a revised band plan for the paired and unpaired spectrum used by the fixed service from 17.7-18.3 GHz and 19.319.7 GHz, consisting of a variety of channel bandwidths, primarily narrower bandwidths, and a block of unpaired spectrum from 17.7-17.74 GHz and also designated a contiguous 600 megahertz block of one-way spectrum from 17.7-18.3 GHz for use by Multichannel Video Programming Distributors (MVPDs).  Rechannelization of the 17.7-19.7 GHz Frequency Band for Fixed Microwave Services under Part 101 of the Commission’s Rules, WT Docket No. 04-143, Report and Order, 21 FCC Rcd 10900 (2006), (FCC 06-141).
  While most of the proposed changes remove channels that are no longer allocated to the fixed service, in one instance we propose to add replacement channels, i.e., we proposed replacing the 12 frequency pairs in section 74.502(c)(1)(i) of the rules with the 5 megahertz channels from section 101.147(r)(5) in Appendix B.  We also propose to update sections 101.95(a) and 101.147(a) to remove expired text and to remove six sections concerning expired policies governing fixed service relocation from the 18.3-19.3 GHz band, i.e., sections 101.83 through 101.91 and 101.97.  See Appendix B for the proposed revisions of sections 74.502(c), 74.602(g), 78.18(a)(4), 101.95(a), and 101.147(a) and (r).  We request comment on these proposals.
33. Second, we propose to revise footnote NG62 to permit the fixed stations authorized pursuant to the 10 listed call signs to continue to operate indefinitely on a secondary basis.  The Commission adopted footnote NG62 when it deleted the primary fixed and mobile service allocations from the 28.529.1 GHz and 29.25-29.5 GHz bands.  Footnote NG62 states that, in the 28.5-29.1 GHz and 29.25-29.5 GHz bands, stations in the fixed-satellite service shall not cause harmful interference to, or claim protection from, stations in the fixed service operating under 18 listed call signs; however, only 10 of these call signs are currently active. On Feb. 28, 2022, Commission staff conducted a Site Based Search of the Universal Licensing System (ULS) and found that ten licenses authorize common carrier fixed point-to-point microwave (radio service code CF) operations in the 28.529.1 GHz and 29.25-29.5 GHz bands.  Specifically, one license authorizes operational fixed use (station class FXO) in the 28.5-29.5 GHz band in Honolulu, Hawaii (call sign WML443) and nine licenses authorize temporary fixed operations (station class FX5) in the 29.1-29.5 GHz band in a total of 15 states (call signs KIL20, KME49, KQG58, KQH74, KSA96, KSE73, KZS88, WMP367, and WSL69).
  We note that WRC-19 and the Commission’s rules permit earth stations in motion (ESIMs) to operate in these frequency bands. 47 CFR § 25.202(a)(10)(i)-(ii); Appx. A, footnote 5.517A.
  The proposed secondary status of these fixed stations would recognize that ESIMs, which may operate anywhere without coordination with the fixed stations, may cause intermittent interference to these fixed stations.  See Appendix B for the proposed text of revised footnote NG62.  We request comment on these proposals.
34. Third, we request comment on whether we should raise the non-Federal secondary fixedsatellite service (space-to-Earth) allocation in the 18.142-18.3 GHz band (158 megahertz) to primary status, i.e., co-equal with the non-Federal primary fixed service allocation in the band.  If adopted, this upgrade of allocation status would provide receiving earth stations with interference protection from laterlicensed fixed stations that are used for part 74 and part 101 Multichannel Video Programming Distributor (MVPD) and part 78 cable television relay service (CARS) operations that operate in accordance with the proposed rules in this section.  We tentatively conclude this should result in significantly heavier earth station use of this band in the future, thereby enhancing spectrum efficiency.  As background, we note that there are seven part 78 CARS licenses, which are located in three California counties and Maui Island, Hawaii; and 35 grandfathered fixed service licenses that authorize operations in the 18.142-18.3 GHz band. On March 1, 2022, Commission staff conducted a General Menu (GENMEN) license search (by site/frequency) and found the following under the heading “FCC Media Bureau Cable Operations and Licensing System Database” in the 18.142-18.3 GHz band:  1) the 17,982-18,300 MHz band is licensed in Vacaville, Solano County, California (call sign WLY-820); 2) the 18,138-18,294 MHz band is licensed in Blue Ridge and Porterville, Tulare County, California (call signs WGV-505 and WHZ-511); 3) the 18,148-18,304 MHz band is licensed in Puu Nianiau, Maui County, Hawaii (call sign WBM742); and 4) the 18,15418,226 MHz band is licensed in Georgetown and Auburn Lake and the 18,25018,334 MHz band is licensed in Placerville, El Dorado County, California (call signs WLY796, WLY-797, and WGK-480).  On Feb. 28, 2022, Commission staff conducted a Site License Search of the Universal Licensing System (ULS) and found 35 active licenses that authorize grandfathered operations (i.e., operations not in accordance with the current part 101 channel plan) in the 18.142-18.3 GHz band.  The 35 grandfathered fixed service licenses consist of 25 temporary fixed station (station class FX5) licenses [18 common carrier point-to-point microwave (radio service code CF) licenses, which authorize nationwide (one license), continental (three), multistate (seven), and statewide (eight) use, and six local television transmission (CT) licenses, which authorize nationwide use] and 10 operational fixed station (station class FXO) licenses (eight microwave industrial/business pool (MG) licenses and two microwave public safety pool (MW) licenses, all of which authorize local area use).  We note that grandfathered licensees are required to disclose locations and technical parameters of their links during the coordination process.
  In contrast, as of August 26, 2022, there are 222 licenses for earth station reception in the 18.142-18.3 GHz band and there are 414 pending applications for earth stations that would receive in the band. While conducting the GENMEN license search on March 3, 2021, Commission staff noted that there were 119 currently licensed and pending International Bureau Filing System (IBFS) files; however, as of August 26, 2022, there are 636 currently licensed and pending IBFS files.  Id.

35. Finally, we request comment on whether we should allow the continued operation of existing CARS licenses that authorize operation in the 18.3-18.304 GHz and 18.3-18.334 GHz bands in Puu Nianiau, Hawaii, and Placerville, California, respectively, and  revise footnote US139 to codify that these fixed station operations may continue to operate indefinitely under the existing conditions.
7. Deletion of the Radionavigation-Satellite Service from the 149.9-150.05 MHz and 399.9400.05 MHz Bands
36. Consistent with the WRC-15 Final Acts, we propose to delete the radionavigation-satellite service allocation from the 149.9-150.05 MHz and 399.9400.05 MHz bands. NTIA WRC-15 Implementation Recommendations, Attachment 1 – Annexes 9.2b and 9.2c, 88-89.
  WRC-15 deleted this allocation because it had expired pursuant to footnote 5.224B. Footnote 5.224B was adopted at the 1997 World Radiocommunication Conference.  The WRC-15 Admin Order removed footnote 5.224B from the Commission’s rules.  WRC-15 Admin Order, supra note 3, Appx. at 13 (amendatory instruction 9.b).
  In the U.S. Table, the 149.9-150.05 MHz and 399.9400.05 MHz bands are Federal/non-Federal shared bands that are allocated to the mobilesatellite service (Earth-to-space) and the radionavigation-satellite service on a primary basis.  This proposal would make these two bands – totaling 300 kilohertz – exclusively allocated to the mobilesatellite service (Earth-to-space).  We seek comment on this proposal.
B. Terrestrial Issues
1. Amateur Service in the 5351.5-5366.5 kHz Band
37. We propose to allocate the 5351.55366.5 kHz band to the Amateur Radio Service on a secondary basis and seek comment on whether the amateur service should keep the existing channels they use in the 60 meter band. Amateur radio service licensees often refer to frequency bands by the wavelength of the signal.  The bands at issue here are often collectively referred to as the 60 meter band.
  During WRC-15, the International Telecommunication Union allocated this band to the amateur service on a secondary basis in all ITU Regions.  The ITU generally set the maximum radiated power at 15 watts (W) equivalent isotropically radiated power (EIRP), which is equivalent to 9.15 W effective radiated power (ERP). WRC-15 adopted footnote 5.133B, which is shown in Appendix A and that we summarize as follows:  Stations in the amateur service using the 5351.5-5366.5 kHz band must not exceed a maximum EIRP of 15 watts, except that in 33 of the 35 ITU Member States in Region 2 a higher maximum EIRP is permitted, i.e., 20 W in Mexico and 25 W in all other ITU Member States in Region 2 – except for the United States and Canada.  However, Canada subsequently decided to permit stations in the amateur service using the WRC15 band to operate with a maximum ERP of 100 W; see note 102, below.

38. These frequencies are currently part of the 5275-5450 kHz band, which is allocated for Federal/non-Federal shared use, on a primary basis, to the fixed service and, on a secondary basis, to the mobile except aeronautical mobile service.  Footnote US23 to the Allocation Table currently provides a secondary allocation to the amateur service on five discrete channels – each with a maximum bandwidth of 2.8 kilohertz and centered on the frequencies 5332, 5348, 5358.5, 5373, and 5405 kHz. While footnote US23 of the Allocations Table does not have an explicit bandwidth limit, it limits use of these frequencies to specified emission types and designators, which in effect limit the bandwidth to a maximum of 2.8 kilohertz, i.e. phone (2K80J3E), data (2K80J2D), RTTY [narrow-band direct-printing telegraphy emissions having specified designators] (60H0J2B), and CW [International Morse code telegraphy emissions having specified designators] (150HA1A).  47 CFR §§ 2.101, 2.102, 2.106 footnote US23, 97.3(c)(1), (c)(7).
  However, pursuant to Commission rules, stations in the amateur service may transmit on these frequencies with a maximum radiated power of 100 W ERP – over ten times more powerful than WRC-15’s EIRP limit. Footnote US23 of the Allocations Table and section 97.313(i) of the Commission’s rules state that amateur service use of these frequencies is restricted to a maximum ERP of 100 watts “PEP” and that no station may transmit with an ERP exceeding 100 watts “PEP,” respectively.  These requirements are inconsistent with the definitions in part 97 of the Commission’s rules, i.e., PEP is the average power supplied to the antenna transmission line by a transmitter during one RF cycle at the crest of the modulation envelope taken under normal operating conditions and ERP is the product of the power supplied to the antenna and its gain relative to a halfwave dipole in a given direction.  47 CFR § 97.3(b)(2)-(3), (9).  Our review finds that these rules were intended to limit the radiated power to 100 watts ERP based on the 2006 agreement between NTIA and ARRL and, to minimize confusion we refer to this limit in our discussion.  Petition for Rule Making of ARRL, RM11353, at Exhibit A (filed Oct. 10, 2006); 47 CFR § 97.313(k), (l).
  NTIA recommends that we conform footnote US23 to the WRC-15 Final Acts by allocating the 5351.55366.5 kHz band to the amateur service on a secondary basis, removing the four existing amateur channels outside this proposed new amateur band, and restricting the maximum radiated power of amateur operations in the band to 15 W EIRP. NTIA WRC-15 Implementation Recommendations, Attachment 1 – Annex 1.4, 29 (emphasis in original).
  Federal agencies use the larger 5275-5450 kHz band for services that include military, law enforcement, disaster relief, emergency, and contingency operations. As of March 2022, there are 36 Federal assignments in the 5351.55366.5 kHz band.  
  Most non-Federal operations in the 60 meter band are part 90 industrial business pool land mobile  operations.  As of April 17, 2023, there are 44 non-Federal licenses that authorize operations in the 5351.5-5366.5 kHz segment and 44 non-Federal licenses that authorize operations in the 5275-5450 kHz band.  Licenses that authorize operations in the 5351.5-5366.5 kHz segment authorize disaster or long distance communications pursuant to footnote US22 on specific frequencies in the 5005-5450 kHz band.  47 CFR §§ 2.106 footnote US22, 90.264, 90.266.

39. In 2017, ARRL, the National Association for Amateur Radio (ARRL), filed a petition for rulemaking asking the Commission to allocate the 5351.55366.5 kHz band to the amateur service on a secondary basis, as provided in the WRC-15 Final Acts, and also to retain the four amateur service channels that are outside this band (i.e., the frequencies 5332 kHz, 5348 kHz, 5373 kHz, and 5405 kHz) Petition for Rule Making, ARRL, RM-11785 (filed Jan. 12, 2017) (ARRL Petition); Comments of ARRL, RM11785 (filed March 29, 2017).  The Commission issued a public notice announcing receipt of this petition on February 16, 2017.  See Public Notice Consumer & Governmental Affairs Bureau Information Center Petition For Rulemakings Filed, Report No. 3071 (rel. Feb. 16, 2017).  As of Feb. 28, 2022, there were 119 filings in RM11785, most of which support the ARRL petition.
  Further, ARRL supports using the same operating rules in terms of permitted emission types, power level, and access by class of amateur licensee for the new contiguous allocation that is currently applied to the existing five amateur channels. ARRL Petition at 18.
  Essentially, ARRL supports extending the provisions of footnote US23 of the Allocation Table and section 97.303(h) of the Commission’s rules that apply to the existing five amateur channels, including the 100 watt ERP limit, to the new allocation. Id. at 19.
  Therefore, ARRL disagrees with applying the 15 W EIRP limit suggested in the WRC-15 Final Acts.  While most commenters support implementation of the ARRL Petition as filed, some commenters disagreed with various aspects of the ARRL Petition as addressed below.  Some even argue that the entire 60 meter band should be opened for amateur use at higher power because they are not aware of any complaints of harmful interference. See, e.g., Daniel P Schaff Comments at 1; Michael Goltz Comments at 1; Danny Douglas Comments at 1.
  Finally, we note that Canada has essentially implemented the same rules as ARRL has requested. See Decision on Proposed Revisions to the Canadian Table of Frequency Allocations, SMSE-07-18, April 2018, pages 1-2.

40. We propose to modify footnote US23 and part 97 of our rules to implement the new international allocation at 5351.5-5366.5 kHz, but also seek comment on whether we should maintain the existing four channels at 5332, 5348, 5373, and 5405 kHz that are outside of the new allocation. Specifically, we propose to make the following amendments to part 97 of the rules:  1) replace the five center frequencies with the 5351.55366.5 kHz band in sections 97.301(b)-(d) and 97.305(c); 2) simplify the frequency sharing requirements in section 97.303(h) by stating that amateur stations transmitting in the band must not cause harmful interference to, and must accept interference from, stations authorized by the United States and other nations in the fixed service; and other nations in the mobile except aeronautical mobile service; and 3) revise the emission standard in section 97.307(f)(14) by removing unneeded text, including the unneeded upper sideband and Morse telegraphy restrictions (as requested by ARRL in its petition).  Appx. B.
  Under this proposal, amateurs would have access to a contiguous 15 kilohertz-wide band.  Allowing amateurs to use these internationally-harmonized frequencies could facilitate amateur communications across international borders.  We note however, there is significant opposition from the amateur community regarding the removal of the four discrete channels at 5332, 5348, 5373, and 5405 kHz from amateur use, as requested by NTIA.  See, e.g., Steve Schroder Comments at 1; Ronald F. Henry Comments at 1; James J. Martin Comments at 1.
  An argument could be made that amateur operations should remain on harmonized international frequencies because of the long-range propagation of these frequencies.  Further, amateur licensees also have access to other high frequency (HF) bands at 3 and 7 MHz, so we believe there should be sufficient spectrum options for amateur operations without deviating from the internationally harmonized spectrum.  However, some commenters contend that the amateur community has been using the four discrete channels at 5332, 5348, 5373, and 5405 kHz that fall outside of the proposed band for some time and argue that these channels are important in responding to disasters. See, e.g., Roland Wayne Woodhams Comments at 1; Troy M King Comments at 1; Hugh Bahar Comments at 1; ARRL Comments at 9.
  We seek comment on this issue and what spectrum in the 60 meter band should be made available for amateur use.     
41. Alternatively, we seek comment on whether the four discrete channels at 5332, 5348, 5373, and 5405 kHz should be kept available for limited amateur use under certain conditions or only in response to disasters.  For example, could the channels be authorized for amateur use during disasters as part of the Military Auxiliary Radio System (MARS) or SHAred RESources High Frequency Radio (SHARES) programs where participating amateur licensees can operate on Federal channels in coordination with the Department of Defense or Department of Homeland Security, respectively?  Should we permit amateur stations participating in established emergency communications programs such as the Amateur Radio Emergency Service (ARES) or the Radio Amateur Civil Emergency Service (RACES) to use the additional channels or operate at higher power during emergencies and drills? RACES is a radio service using amateur stations for civil defense communications during periods of local, regional, or national civil emergencies.  47 CFR § 97.3(a)(38).  ARES is an ARRL program for radio amateurs who participate in emergency communications.  See http://www.arrl.org/ares (last visited Feb. 28, 2022).
  Could the discrete channels be maintained under lower power or under other conditions that might reduce their potential to interfere with primary allocation services in the band?  If so, we invite comment on whether the existing discrete channels should continue to be used for secondary amateur use and under what rules and conditions.
42. While many amateur commenters argue they should be permitted access to more of the 60 meter band because they are not aware of any complaints of interference arising from their current operations, we note there are a variety of important non-Federal and Federal fixed and mobile except aeronautical mobile service operations in the band where even rare instances of interference could endanger public safety.  Therefore, we tentatively find that the spectrum requirements for the amateur service in the 50055450 kHz band should be met by the WRC-15 amateur band and that only the four existing amateur channels at 5332, 5348, 5373, and 5405 kHz that are outside this band should be considered in this proceeding.  Nevertheless, we seek comment on this idea.  Commenters that support expanded access to the 60 meter band should provide information regarding how heavily the five amateur frequencies in the 52755450 kHz band are used and why additional amateur spectrum in this frequency range is needed if we adopt the proposed allocation.  
43. Power.  ARRL seeks a maximum radiated power limit of 100 W ERP for the new secondary amateur allocation and to maintain the existing maximum radiated power limit of 100 W ERP for the existing discrete channels at 5332, 5348, 5373, and 5405 kHz.  ARRL argues that such an implementation would support amateurs engaged in emergency and disaster relief communications to more reliably, flexibly, and capably conduct those communications; that imposing a maximum radiated power limit of 15 W EIRP would render the band unsuitable for emergency and public service communications; that the lower power limit is insufficient to permit reliable communications on the paths that are most critical; and that this reduced radiated power limit is not necessary to protect primary services from interference. ARRL Petition at 3, 19-21.

44. Harold Ross Lambert and Michael Goltz argue that the power limit should be increased to 500 W to deal with propagation challenges in disaster communications; Harold Ross Lambert Comments at 1; Michael Goltz Comments at 1.
 and Milton K. Miller supports 500 W power with the use of more efficient antennas. Milton K. Miller Comments at 1. 
  Phillip Finkle urges for at least 200 W of power designated as output power instead of ERP because ERP is difficult to measure. Phillip Finkle Comments at 1.
  Janis Carson initially expresses concern over allowing U.S. amateurs to operate at much higher powers than the international standard, suggesting a compromise power of 30 W because digital modes are very effective at lower power and world-wide communications can be achieved at lower power levels like 5 W. Janis Carson March 13, 2017 Comments at 1.
  However, in later comments Ms. Carson supports the ARRL proposal to allow 100 W for “more reliable communications in an environment of high static crashes.” Janis Carson December 2, 2019 Comment at 1.
  William Springer urges the adoption of the 15 W power limit in the WRC-15 Final Acts because he contends that newer digital modes are more efficient, and so weaker signals are not an impediment to achieving communication. William Springer Comments at 1, William K. Mabry Comments at 1.
  Finally Hugh Bahar cautions that deviating from limits agreed to at the international level is unwise and could lead to other countries ignoring the standards and could be viewed as an act of bad faith. Hugh Bahar Comments at 1.

45. Several commenters also argue for more flexibility in the types of antennas permitted in the 60 meter band. The rules do not limit antenna gain and thus it is unclear why commenters have made this assertion.  These comments appear to relate to section 97.313(i) of the rules, which states that:  1) for the purpose of computing ERP, the transmitter PEP will be multiplied by the antenna gain relative to a half-wave dipole antenna; 2) a half-wave dipole antenna will be presumed to have a gain of 1 (0 dBd); and 3) licensees using other antennas must maintain in their station records either the antenna manufacturer's data on the antenna gain or calculations of the antenna gain.  47 CFR § 97.313(i).
  Scott Wright and George Dominick contend that antennas with gain greater than 0 dBi should be allowed since they are essential for efficient communications during an emergency. Scott Wright Comments at 1, George Dominick Comments at 1. 
  In contrast, Mathew Pitts does not support increasing the permitted antenna gain and contends the power should range between 15 and 30 W. Mathew Pitts Comments at 1. 
 
46. We seek comment on the appropriate power limit for the new internationally harmonized amateur allocation and for the discrete channels if they are maintained for amateur use.  We tentatively conclude that limiting the radiated power of amateur stations to 15 W EIRP would reduce the potential of harmful interference to incumbent primary operations, while maintaining consistency with the power limits established internationally for amateur operations in this band.  However, the majority of the amateur comments are opposed to lower power limits and neighboring countries in Region 2 permit power levels higher than 15 W EIRP. See, e.g., Blair Balden Comments at 1; Bruce Pitman Comments at 1; Harold Ross Lambert Comments at 1; Roland Wayne Woodhams Comments at 1. 
  We agree with certain commenters that the long-range propagation capabilities of these frequencies is likely to allow efficient communications at low-power levels, but there may be instances where more power is needed to deal with propagation challenges.  
47. We acknowledge that valid arguments may exist for adopting power limits above 15 W up to 100 W.  For example, footnote 5.133B of the Allocations Table, which addresses this international allocation, outlines a power limit of 20 W EIRP for Mexico and 25 W EIRP for all Latin American countries and for many Caribbean countries/territories. See 47 C.F.R § 2.106 footnote 5.133B.
  Further, a review of our licensing database indicates other licenses with higher allocation status operating at power levels ranging from 15 W up to as high as 5000 W.  Accordingly, we seek to build a more comprehensive record on the appropriate power limit for 60-meter band amateur operations.   Interested parties seeking a power limit above the proposed 15 W EIRP limit should explain how much power would be appropriate, and how higher power limits would affect other operations in the 60-meter band?  For example, should we allow the higher power allowed in other countries in ITU Region 2, such as Mexico and most Caribbean countries?  Should we allow higher power during times of emergency drills/response or as part of programs where Amateur licensees support Federal emergency response?  Should higher power only be permitted during disasters or drills supporting disaster relief?  If, going forward, the discrete channels are permitted to be used by amateur operators under certain parameters or during disasters, what power limits should apply and when?  What other conditions or considerations should be applied to amateur use of the 60 meter band? 
48.  Further, we seek comment on how the limit should be specified in the rules.  Specifically, should the power limit be defined in terms of EIRP to be consistent with the WRC-15 recommendation, or through some other means, such as ERP or transmitter output power?  While some commenters argue that radiated power limits are difficult to calculate for certain types of antennas, See e.g., Louis Lee Grande Barrett Comments at 1 (arguing “[n]o one can easily determine their wire antenna gain (or other) without intensive mathematical analysis and a knowledge of logarithms to determine ERP. Please conform to a Power Output as on other bands and disregard the antenna gain/ERP ratings.”)
 we find that amateur licensees are supposed to study the radio arts and should be capable of determining their operating power.  We seek comment on the pros and cons of the various power limit alternatives and which method is best for the 60 meter band.  If we adopt a radiated power limit, we do not propose to adopt antenna limitations because a radiated power limit would ensure that excess power is not used, and flexibility in antenna choices may lead to spectrum efficiencies because the signal will propagate in its intended direction.  Nevertheless, we seek comment on whether, and, if so what, antenna limitations are appropriate for amateur operations in this band using these different power limit measurements and how the Commission’s decision could affect how these frequencies would be used by the amateur community.
49. Channelization.  ARRL and several commenters argue that the new allocation should not designate sub-bands for various modes of operation to enable maximum flexibility to avoid interference with other operations. ARRL Petition at 18.  See also e.g., Phillip Finkle Comments at 1, Scott Wright Comments at 1. 
  Janis Carson contends channelization is wasteful because narrowband modes can operate at less than three kilohertz and flexibility is need to address prevailing circumstances. Janis Carson March 13, 2017 Comments at 2.
  She adds that a maximum bandwidth of 500 Hertz should be allowed in the new contiguous allocation. Id. at 3.
  Charles Powell supports the ARRL request and contends that amateur equipment is not designed to maintain a high level of frequency accuracy and that such a design change would make equipment prohibitively expensive. Charles Powell Comments at 1. 
  However, William Springer argues that the new allocation should be channelized into five 3 kilohertz channels to promote efficiency and avoid overlapping transmissions. William Springer Comments at 1. Other commenters supporting channelization of the band include: John Rohow Comment at 1; Ronald F. Henry Comment at 1.
  Benjamin Russell also supports five discrete channels, but suggests creating ten overlapping channels for narrowband carrier wave (CW) use. Benjamin Russell Comments at 1.  CW (the abbreviation coming from the fact that it uses a Carrier Wave, or a Continuous Wave that is interrupted) is defined as international Morse code telegraphy emissions having designators with A, C, H, J or R as the first symbol; 1 as the second symbol; A or B as the third symbol; and emissions J2A and J2B.  47 CFR § 97.3(c)(1).
  Ronald F Henry contends that channelization would facilitate sharing with Federal users and, given there are several bands available for amateur use, the “60 Meter band must be set aside for emergency communications as the primary use and as such, channelization is desired to protect both the primary and secondary user.” Ronald F. Henry Comment at 1. 

50. We propose that the 5351.5-5366.5 kHz band should not be channelized or have sub-bands.  Due to the wide variety of potential applications and the need to protect other communications, dividing the band into channels may lead to inefficient spectrum use.  However, we agree with commenters who state that some wideband digital emissions could create spectrum sharing problems, and so we propose a maximum emission bandwidth of 2.8 kilohertz for amateur operations in this band.  We seek comment on this proposal and whether there are other limits or technical rule changes necessary to ensure reliable and efficient use of this band.  
51. Station Class and Permitted Uses.  ARRL and certain other commenters state that only amateurs with a General Class license or higher should be allowed to use the new allocation, because Technician Class license holders may not have the experience to operate consistent with the interference avoidance protocols needed for the band. ARRL Petition at 21; Janis Carson March 13, 2017 Comments at 1; Hugh Bahar Comments at 1.
  William Springer opposes the allowance of CW transmissions in the band because he contends that they are outdated and inefficient, but supports the use of any commonly-available, unencrypted digital transmission mode limited by a maximum occupied bandwidth that fits within the channel. William Springer Comments at 1.
  Scott Wright supports the allowance of CW, arguing that several CW emissions can fit within a small amount of bandwidth. Scott Wright Comments at 1.
  Janis Carson and Hugh Bahar oppose the allowance of automatically controlled digital stations and wideband digital modes that could block the entire allocation and could cause interference without busy channel detection. Janis Carson March 13, 2017 Comments at 2, Hugh Bahar Comments at 1.
  In her reply comments, Ms. Carson adds that the new allocation should be used for narrowband digital or CW and that the discrete channels, along with the one 3 kHz channel contained within the new allocation, could remain for use of single-side band (SSB) voice or wider digital modes. Janis Carson Reply Comment at 2. 
  Ms. Carson also suggests not allowing any automatic store and forward email systems in the 60 meter band, claiming that these systems have a high potential to cause interference due to the “hidden transmitter” effect, where the offshore initiating station cannot hear a primary user in the skip zone of the shore based relay station. Janis Carson December 2, 2019 Comment.
  Finally, W. Lee McVey contends that the 60 meter band rules should ensure that only publicly documented digital codes operate in the band to prohibit encrypted communications. W. Lee McVey August 30, 2021 ex parte at 1-2.
 
52. Consistent with the current amateur class requirements for the 60 meter band, See 47 C.F.R. § 97.301.
 we propose to permit amateurs holding a General Class license or higher to use the 5351.5-5366.5 kHz band.  We agree with commenters that the long-range propagation characteristics in the band combined with the need to protect important safety of life communications by Federal operations potentially requires a higher level of radio knowledge to ensure the spectrum is properly shared. See, e.g., Hugh Bahar Comments at 1; ARRL Comments at 9; Janis Carson Comments at 1.
  We seek comment on this proposal.  Further, if we maintain the four existing discrete channels at 5332, 5348, 5373, and 5405 kHz outside of the international allocation, we propose that those channels also be permitted for General Class licensees or higher.  We seek comment on this proposal and other alternatives.  For example, if we adopt the new allocation and keep the existing discrete channels, should different amateur classes be permitted on the new allocation versus the discrete channels?  If we allow station classes below General Class licensees to access the 60 meter band, what conditions should be applied?  For example, should certain classes be permitted to operate in certain modes (i.e., voice vs. digital) or at certain times (e.g., only in response to a disaster)?  Given the limited spectral resource at issue, commenters supporting more flexible use should support their comments with suggested safeguards or ideas on how the spectrum can be efficiently used without interfering with primary allocation operations.  
53. At this time, we are not proposing to preclude CW or any other radio technique currently permitted in the 60 meter band because the record is inconclusive on whether certain modulation methods should be prohibited.  However, we note that the amateur rules generally preclude encrypted operations, See generally 47 C.F.R. § 97.309 (outlining various requirements for RTTY and data emissions including the requirement that digital codes must not be transmitted for the purpose of obscuring the meaning of any communication).
 and so we seek comment on whether the 60 meter band rules need to be clearer on what types of digital operations are permitted.  As discussed above, we propose to limit the emission bandwidth to 2.8 kilohertz, which may limit some techniques.  We seek comment on these proposals and encourage the amateur community to attempt to reach consensus on what radio techniques should be permitted, given the limited amount of spectrum available, the need to use this spectrum efficiently, and the importance of ensuring that the primary users are protected from harmful interference.
2. Amateur Service in the 420-450 MHz Band
54. Based on a request from NTIA, we propose to update the coordination and contact information in footnote US270 for the areas wherein the peak envelope power of an amateur station operating in the 420-450 MHz (70 cm) band is generally limited to 50 watts, and to revise the cross reference to this footnote in section 97.313(f) of the rules. See e-mail from Charles Cooper, Associate Administrator, Office of Spectrum Management, NTIA, to Ronald Repasi, Acting Chief, FCC Office of Engineering and Technology, August 8, 2021, attachment at 1-2.
  See Appendix B for the proposed text of footnote US270 and section 97.313(f).  We request comment on these proposals.  
3. Maritime On-board Communication Stations (457/467 MHz)
55. We propose to revise footnote US288 to make a limited number of narrowband channels from the international channel plan adopted at WRC-15 available for use by onboard communication stations.  An on-board communication station is a lowpowered mobile station in the maritime mobile service used for internal communications on board a ship, or between a ship and its lifeboats and life-rafts during lifeboat drills or operations, or for communication within a group of vessels being towed or pushed, as well as for line handling and mooring instructions. 47 CFR §§ 2.1(c), 80.5.
  Our proposals are intended to benefit the maritime industry by making available a subset of the internationally-harmonized narrowband channels for onboard communication use while ships are in U.S. territorial waters. WRC-15 revised footnote 5.287 to require that the characteristics of on-board communications stations conform to Recommendation ITU-R M.1174-3.  Subsequently, Recommendation ITUR M.1174-3 was revised to correct the frequency deviation for 6.25 kilohertz channels, and consequently, Recommendation ITU-R M.1174-4 is now in force.  For the purposes of this section, internationally-harmonized channel means that the center frequency is specified in Recommendation ITU-R M.1174-4 and that this frequency is available, or is proposed to be made available, for licensed use in part 80 of our rules.  Recommendation ITUR 1174-4 includes the following:  “Provision is made for 25 kHz or 12.5 kHz channel spacing for analogue and digital technologies.  In addition, 6.25 kHz channel spacing may also be used for digital technology.”  In this section, we refer to the 25, 12.5, and 6.25 kilohertz-spaced channels in the 457.5125457.6125 MHz, 467.5125-467.5875 MHz, and 467.7375467.8375 MHz bands as “25 kilohertz channels,” “12.5 kilohertz channels,” and “6.25 kilohertz channels,” respectively.  With respect to the United States, “territorial sea means the waters, 12 nautical miles wide, adjacent to the coast of the United States and seaward of the territorial sea baseline” for “[i]nterpreting international law” and the other purposes specified in 33 CFR section 2.22(a), internal waters means the waters shoreward of the territorial sea baseline, and territorial waters of the United States means the territorial sea and the internal waters of the United States.  Normally, the territorial sea baseline is the mean low water line along the coast of the United States.  See   33 CFR subpart B at §§ 2.20, 2.22(a), 2.24(a), 2.26, and 2.36; Recommendation ITU-R M.1174-4 (10-2019), Technical characteristics of equipment used for onboard vessel communications in the bands between 450 and 470 MHz.
  Our overarching goals in making these proposals are to minimize the potential for intermittent and harmful interference to stations in the land mobile and fixed services that operate on the same or adjacent frequencies to on-board communication stations and to promote more efficient and effective use of the available spectrum, while fully meeting the operational requirements of ship station licensees for on-board communication stations. The 456-460 MHz and 462.7375-462.5375 MHz bands are allocated to the fixed and land mobile services on a primary basis for non-Federal use and the bands are available for licensing to applicants in the Industrial/Business Radio Pool pursuant to our part 90 rules for Private Land Mobile Radio Services.  The 467.5375467.7375 MHz band is allocated to the land mobile service on a primary basis for non-Federal use and this band is licensed by rule pursuant to our part 95 rules for Personal Radio Services.  This band is shared between the Family Radio Service (part 95 subpart B) and the General Mobile Radio Service (part 95 subpart E).  A ship station license permits operation of all maritime services transmitting equipment on board a vessel.  In contrast, a ship station that is licensed by rule is limited to certain part 80 VHF frequencies.  In particular, ship stations that are licensed by rule do “not travel to foreign ports” and are not eligible for on-board communication stations.  47 CFR §§ 80.13, part 90 subpart C, part 95 subparts B and E.

56. Footnote US288 and section 80.373(g) of the rules make seven internationallyharmonized frequencies in the 457.5125-457.5875 MHz and 467.5125467.5875 MHz bands (150 kilohertz) and five other frequencies available for use by on-board communication stations in U.S. territorial waters (275 kilohertz in total). The seven internationally-harmonized frequencies are 457.525 MHz (channel 1 or 11), 457.5375 MHz (channel 12), 457.550 MHz (channel 2 or 13), 457.5625 MHz (channel 14), 457.575 MHz (channel 3 or 15), 467.5375 MHz (channel 22), and 467.5625 MHz (channel 24), which are specified in Recommendation ITU-R M.1174-4.  The five frequencies that are not internationally harmonized are 457.600 MHz, 467.750 MHz, 467.775 MHz, 467.800 MHz, and 467.825 MHz.  Channels 1-3 and the five non-harmonized frequencies are 25 kilohertz channels and channels 11-15, 22, and 24 are 12.5 kilohertz channels.  Footnote US288 does not currently prohibit onboard communications stations on foreign-flagged vessels from operating on other internationally-harmonized channels in U.S. territorial waters that are not licensed for such use by the Commission, and thus stations in the fixed and land mobile services may experience intermittent interference from on-board communication stations that operate in up to 275 kilohertz of spectrum (457.5125-457.6125 MHz, 467.5125467.5875 MHz, and 467.7375467.8375 MHz) under the current rules.
  Specifically, section 80.373(g)(1) states that the frequencies 457.525 MHz, 457.550 MHz, 457.575 MHz, and 457.600 MHz may be used by on-board repeater stations An on-board repeater is a radio station that receives and automatically retransmits signals between on-board communication stations.  On-board frequencies are assignable only to ship stations.  When an on-board repeater is used, paired frequencies must be used.  On-board repeater frequencies must be used for single-frequency simplex operations.  47 CFR §§ 80.5, 80.1177.
 and by unpaired onboard mobile stations (i.e., single-frequency simplex operation Simplex operation is the operating method in which transmission is made possible alternatively in each direction of a telecommunication channel, for example, by means of manual control.  Duplex operation is the operating method in which transmission is possible simultaneously in both directions of a telecommunication channel.  In general, duplex operation requires two frequencies and simplex operation may use either one or two.  47 CFR § 2.1(c).
) and that four frequencies in the 467.7375-467.8375 MHz band (i.e., 467.750, 467.775, 467.800, and 467.825 MHz) may be used by on-board mobile stations in twofrequency repeater systems.  In addition, section 80.373(g)(2) states that, where needed, equipment designed for 12.5 kilohertz channel spacing using the additional frequencies 457.5375 MHz, 457.5625 MHz, 467.5375 MHz, and 467.5625 MHz (i.e., channels 12, 14, 22, and 24) may be introduced for on-board communications; 47 CFR § 80.373(g)(2).
 however, no use of these channels is currently authorized. The 12.5 kilohertz channels are internationally-harmonized channels centered on the frequencies 457.5375 MHz, 457.5625 MHz, 467.5375 MHz, and 467.5625 MHz (designated as channels 12, 14, 22, and 24, respectively).  As of April 17, 2023, no equipment for use in the 12.5 kilohertz channels had been certified.  47 CFR §§ 2.106 footnote US288, 80.203(a), 80.373(g)(2).

57. WRC-15 revised the international channel plan for on-board communication stations to provide for 6.25 kilohertz channels. See also WRC-15 Admin Order, supra note 3, para. 8, Appx. at 25 (U.S. Table); 47 CFR § 2.106 footnotes 5.287, 5.288.
  This new channel plan, shown in Table 1 below, specifies 40 frequencies that support the use of equipment designed to operate on 25, 12.5, or 6.25 kilohertz channels.  The shaded channels in Table 1 indicate the internationallyharmonized channels that are currently available for use under our rules.

To permit the deployment of more spectrally efficient narrowband equipment, we propose to revise footnote US288 by authorizing on-board communication stations to use 12.5 and 6.25 kilohertz channels in the territorial waters of the United States as described in the following paragraphs.
59. First, we propose to revise footnote US288 to authorize:  1) nationwide use of channels 1115, which are internationally-harmonized 12.5 kilohertz channels, for on-board repeater stations and onboard mobile stations used for singlefrequency simplex operation; Three of the center frequency pairs proposed for 12.5 kilohertz channels are the same as those currently used by 25 kilohertz channels (i.e., channels US1-US3) and the other two proposed center frequencies in the 457 MHz band are the existing 12.5 kilohertz channels (i.e., channels 12 and 14) and they (like channels US1-US3) are paired with center frequencies in the 467 MHz band that are offset from the internationally-harmonized frequencies by 225 kilohertz.
 2) onboard mobile stations to operate nationwide on five non-harmonized frequencies that are 10.225 megahertz higher in frequency than the center frequency of their associated on-board repeater stations (frequencies shown in Table 2, below); and 3) onboard repeater stations to operate on channels 12 and 14 and associated onboard mobile stations operating on channels 22 and 24, respectively, in the Territorial Sea of the United States and at coastal ports and the inland ports of Baton Rouge, Houston, and Portland, and on the waterways and at other ports between these inland ports and the ocean. Channel 24 is co-channel with the Family Radio Service (FRS) and General Mobile Radio Service (GMRS) interstitial channel centered on 467.5625 MHz (± 6.25 kilohertz; FRS channel 8) and channel 24 overlaps the GMRS main channels centered on 467.5500 MHz and 467.5750 MHz (± 10 kilohertz) by 3.75 kilohertz, which is the same overlap as the FRS/GMRS interstitial channel.  Channel 22 also overlaps the GMRS main channel centered on 467.5500 MHz by 3.75 kilohertz.  Because the effective radiated power (ERP) of these FRS and GMRS units must not exceed 0.5 watt, the increase in interference potential to these GRMS main channels would be caused solely by onboard mobile stations transmitting at 2 watts ERP.  47 CFR §§ 95.563, 95.567, 95.1763, 95.1767(c).    
  We request comment on these proposals. Our proposal would make two new frequencies (467.7625 and 467.7875 MHz) available for use by on-board communication stations and would authorize the use of eight existing frequencies with twice the power spectral density (PSD) in their narrower authorized bandwidth, which increases the potential for harmful interference to nearby stations of the fixed and land mobile services that also operate on these frequencies.  PSD is defined as the “power of an emission in the frequency domain, such as in terms of ERP or EIRP, stated per unit bandwidth, e.g., watts/MHz.”  47 CFR § 22.99.  Currently, the part 80 rules limit the ERP of on-board communication stations in the 456-468 MHz band to 2 watts in a 25 kilohertz channel (80 mW/kHz).  If we authorize the same ERP in 6.25 kilohertz, then the PSD would double (160 mW/kHz), thereby increasing the potential for harmful interference over the signal’s bandwidth because the signal’s power is concentrated over a narrower bandwidth.  We intend to address the PSD issue in any subsequent service rules proceeding.

Table 2: Center Frequencies for 12.5 Kilohertz On-board Paired ChannelsChannel For purposes of this proceeding, we are referring to the associated channel pairs as channels US11US15.
On-board Repeater StationOn-board Mobile StationUS11Channel 11 – 457.5250 MHz467.7500 MHzUS12Channel 12 – 457.5375 MHz467.7625 MHzUS13Channel 13 – 457.5500 MHz467.7750 MHzUS14Channel 14 – 457.5625 MHz467.7875 MHzUS15Channel 15 – 457.5750 MHz467.8000 MHz60. Second, we propose to revise footnote US288 to authorize on-board repeater stations and onboard mobile stations used for singlefrequency simplex operation to operate on the 6.25 kilohertz channels 102, 121, 122, 141, and 142 and for on-board mobile stations operating with a repeater station to operate on the 6.25 kilohertz channels 202, 221, 222, 241, and 242, respectively, in the Territorial Sea of the United States and at coastal ports and the inland ports of Baton Rouge, Houston, and Portland, and on the waterways and at other ports between these inland ports and the ocean. The eight 6.25 kilohertz channels are internationally-harmonized channels that are centered on the frequencies 457.534375 MHz, 457.540625 MHz, 457.559375 MHz, 457.565625 MHz, 467.534375 MHz, 467.540625 MHz, 467.559375 MHz, and 467.565625 MHz, which are designated as channels 121, 122, 141, 142, 221, 222, 241, and 242, respectively.  Channels 222, 241, and 242 also overlap the GMRS main channels centered on 467.5500 MHz and 467.5750 by 3.75 kilohertz.
  We request comment on this proposal, noting that eight of these channels overlap the 12.5 kilohertz channels that we are proposing in the previous paragraph (i.e., channels 12, 14, 22, and 24) and that channels 102 and 202 are between lowpower part 90 channels. Channels 102 and 202 are between frequencies in the Group A low power pool (i.e., 457.5125, 457.51875, 467.5125, and 467.51875 MHz), which are limited to a maximum ERP of 2 or 6 watts.  47 CFR § 90.267(b)(2)(i), (b)(4), (c)(2)(i), (c)(3).
  We request comment on these proposals, noting that the use of 6.25 kilohertz channels with center frequencies that are offset from the frequencies used by stations in the fixed and land mobile services by 6.25 kilohertz are expected to enhance spectrum sharing. We also note that the power spectral density of these channels would be four times greater than that of 25 kilohertz channels (320 mW/6.25 kHz).  See supra note 151.
  We also solicit comment on whether we should authorize the use of channel pairs 121/221 on those waterways in the contiguous United States that the Department of Transportation has designated as part of America’s Marine Highway. See https://www.maritime.dot.gov/grants/marine-highways/marine-highway and, in particular, https://cms.marad.dot.gov/sites/marad.dot.gov/files/2021-05/Route%20Designation%20one-pagers%20May%202021.pdf (last visited , 2022).

61. We also propose to revise the text of footnote US288 to state that, in the territorial waters of the United States, footnote 5.287 applies, except that on-board communication stations must transmit only on the listed frequencies and must operate as specified herein.  On-board repeater stations and mobile stations used for singlefrequency simplex operation currently may transmit only in the band 457.5125-457.6125 MHz.  We propose that the preferred frequencies for repeater systems would be 457.525 MHz (channel 1 or 11), 457.5375 MHz (channel 12), 457.550 MHz (channel 2 or 13), 457.5625 MHz (channel 14), 457.575 MHz (channel 3 or 15), and 457.600 MHz paired, respectively, with 467.750 MHz, 467.7625 MHz, 467.775 MHz, 467.7875 MHz, 467.800 MHz, and 467.825 MHz; and the preferred frequencies for singlefrequency operations would be those designated as channels 1-3, 11-15, and 121.  Finally, we propose that use of channels 122, 141, and 142 and channel pairs 12/22, 14/24, 102/202, 121/221, 122/222, 141/241, and 142/242 would be authorized at coastal ports and the inland ports of Houston, Baton Rouge, and Portland, and along the waterways and at other ports between these inland ports and the ocean; however, on-board communication stations would not be able to transmit on these channels while in port and not underway or preparing to get underway. See Appendix B for the proposed text of footnote US288.  We seek comment on these proposals.
62. Finally, we propose to revise footnote US287 by allocating the 457.5125-457.6125 MHz, 467.512375-467.518625 MHz, 467.55625-467.56875 MHz, 467.53125-467.54375 MHz, and 467.7375467.8375 MHz bands (231.25 kilohertz) to the maritime mobile service on a primary basis, by limiting the use of these allocations to on-board communication stations, and by stating that, in these frequency bands, stations in the fixed and land mobile services may not claim protection from interference caused by on-board communication stations operating in accordance with US288 and that onboard communication stations may not claim protection from stations in the fixed and land mobile services.  See Appendix B for the proposed text of footnote US287.  Alternatively, we request comment on whether existing part 90 Private Land Mobile and part 95 Personal Radio Service licensees operating in the 456-470 MHz band should be afforded any protection from interference caused by on-board communication stations operating in accordance with US288.  We observe that the 456-470 MHz band is allocated to the mobile service on a primary basis in all ITU Regions, and request comment on the public interest benefits of both our proposal and the alternative.
4. Deletion of the Broadcasting Service from the 700 MHz Band
63. We propose to delete the broadcasting service allocation in the 698-758 MHz, 775-788 MHz, and 805-806 MHz bands from the non-Federal Table and to revise footnote NG159 by removing the reference to part 74, subpart G.  Between 1998 and 2010, the Commission transitioned the 698-806 MHz (700 MHz) band from television broadcasting use (i.e., TV channels 5269) to public safety and mobile broadband uses. Reallocation of Television Channels 60-69, the 746-806 MHz Band, 12 FCC Rcd 22953 (1998); Reallocation and Service Rules for the 698746 MHz Spectrum Band (Television Channels 52-59), 17 FCC Rcd 1022 (2002); Service Rules for the 698746, 747-762 and 777-792 MHz Bands, 22 FCC Rcd 5289 (2007); Amendment of Parts 1, 2, 25, 73, 74, 90, and 97 of the Commission’s Rules to Make Non-Substantive Editorial Revisions to the Table of Frequency Allocations and to Various Service Rules, 23 FCC Rcd 3775, 3785 para. 27 (2008); and Revisions to Rules Authorizing the Operation of Low Power Auxiliary Stations in the 698-806 MHz Band, 25 FCC Rcd 643 (2010).  Specifically, the 698-758, 775788, and 805-806 MHz bands are licensed for commercial mobile broadband use and as reflected in footnote NG34, the 758775 and 788-805 MHz bands are designated for public safety use.
  Currently, the entire 700 MHz band is allocated to the fixed and mobile services on a primary basis, but the broadcasting service allocation still remains in the 698-758 MHz, 775-788 MHz, and 805-806 MHz portions on a primary basis, and licensees in those bands have the flexibility to provide broadcast services, if they choose. While full-power television stations have vacated this spectrum, part 27 geographic area licenses may provide broadcast services, although none currently list it as a radio service type on their licenses.  There are also television broadcast auxiliary stations remaining in the band.  Footnote NG159 allows these stations to operate indefinitely on a secondary basis to all other stations operating in that band.  Television broadcast auxiliary stations may be authorized pursuant to part 74, subpart F of the rules.  On April 17, 2023, Commission staff conducted a Site Based Search of the Universal Licensing System (ULS) and found that 14 licenses authorize various types of television broadcast auxiliary stations to operate in the 698-806 MHz band (i.e., one TV relay, two TV translator relay, and 11 TV studio-transmitter link stations) and that there are no active licenses that authorize operations pursuant to part 74, subpart G in the band.  WRC-15 Admin Order, supra note 3, para. 15; 47 CFR § 2.106 footnote NG159.
  See Appendix B for the proposed text of footnote NG159.  We request comment on our proposal.  In the event that we delete the broadcast allocation as proposed, we seek comment on whether, and which, part 27 service rules should be modified to reflect the change (e.g., sections 27.3 (Other Applicable Rule Parts), 27.4 (Terms and Definitions), 27.10 (Regulatory Status), 27.13 (License Period), 27.50 (Power Limits and Duty Cycle), and 27.55 (Power Strength Limits)). See, e.g., 47 CFR §§ 27.3, 27.4, 27.10, 27.13, 27.50, 27.55.

5. Deletion of Footnote NG155
64. We propose to remove footnote NG155 from the rules because the frequencies and frequency bands to which it applies are not authorized in part 80 of the Commission’s rules. Footnote NG155 states that: “The bands 159.500-159.675 MHz and 161.375-161.550 MHz are allocated to the maritime service as described in 47 CFR part 80.  Additionally, the frequencies 159.550, 159.575, and 159.600 MHz are available for low-power intership communications.”  47 CFR § 2.106 footnote NG155.
  The ITU has identified the frequencies that can generally be used worldwide for intership communications. ITU Radio Regulations, Vol. 2, Appendix 18 (Rev.WRC-19) at 299.
  Thus, we tentatively conclude that there is no need to specify any other frequencies for intership use. We note that, in the Second Report and Order in PR Docket No. 92-257 that added footnote NG155 to section 2.106 of the Commission’s rules, the Commission declined to adopt the proposed rules for part 80 regarding maritime sharing of private land mobile radio frequencies for intership communications. See Amendment of the Commission’s Rules Concerning Maritime Communications, PR Docket No. 92-257, Second Report and Order and Second Further Notice of Proposed Rulemaking, 12 FCC Rcd 16949, 16894-16896, paras. 70-73
  We request comment on this proposal.
C. Other Matters
65. As a result of discussions regarding the protection of nearEarth operations of deep space missions, Specifically, in examining the wording of footnotes 5.460 and 5.465, parties concluded that there may be an interpretation of these footnotes that is physically impossible to comply with and could lead to constraints on the use of frequencies that are not compatible with the design of a spacecraft meant for deep space operations.  CITEL Proposals to WRC-15, agenda item 9.2 (9.2.2), Addendum 2 to Document 7(Add.23)(Add.2)-E, dated August 21, 2015 (Doc. 4000-9_2_2.doc).
 WRC-15 added a provision in Article 4 of the Radio Regulations (No. 4.24) to describe the use of space research service (deep space) allocations. ITU Radio Regulations, Vol. 1, Article 4 (Assignment and use of frequencies), No. 4.24.
  Similarly, we propose to add a new paragraph to section 2.102 of the Commission’s rules to clarify that:  “Space research systems intended to operate in deep space may also use the space research service (deep space) allocations, with the same status as those allocations, when the spacecraft is near the Earth, such as during launch, early orbit, flying by the Earth and returning to the Earth.”  We request comment on this proposal. This clarification pertains to the following frequency bands:
Table 3: Frequency Bands Allocated to the Space Research Service (Deep Space) in the U.S. TableBandDirectional IndicatorRemarks2110-2120 MHzEarth-to-spacePrimary allocation per footnote US2522290-2300 MHzSpace-to-EarthPrimary Federal and non-Federal allocations7145-7190 MHzEarth-to-spacePrimary Federal & secondary non-Federal use, Goldstone only per US2628400-8450 MHzSpace-to-EarthPrimary Federal and secondary non-Federal allocations12.75-13.25 GHzSpace-to-EarthSecondary international allocation; use limited to Goldstone per US25116.6-17.1 GHzEarth-to-spaceSecondary Federal allocation31.8-32.3 GHzSpace-to-EarthPrimary allocation, limited to Goldstone, per footnote US26234.2-34.7 GHzEarth-to-spacePrimary Federal & secondary non-Federal use, Goldstone only per US262

66. We propose to amend section 2.1(c) of the rules to add or revise the definitions for the terms “meteorological aids land station,” “meteorological aids mobile station,” and “coordinated universal time” in accordance with the WRC-15 adopted definitions.  We also propose to add a definition for the term “frequency band” based on that term’s ITU definition. NTIA WRC-15 Implementation Recommendations, Attachment 1 – Annexes 1.14 and 9.2.1, 70, 101.  We note that NTIA revised its existing term “meteorological aids base station” to “meteorological aids base/land station” in order to avoid confusion.  Because we do not have such an existing term in our rules, it is unnecessary to propose NTIA’s term.  The definition for “frequency band” is taken from the ITU’s online database of Terms and Definitions, https://www.itu.int/pub/R-TER-DB (last visited Feb. 28, 2022).
  The proposed language of these definitions appears in the Appendix.  We seek comment on these definitions.
67. We propose to amend section 2.105(d) of the rules by stating that the footnote references which appear in the United States Table below the allocated service or services apply to more than one of the allocated services, or to the whole of the allocation concerned, and that the footnote references which appear to the right of the name of a service are applicable only to that particular service.  See Appendix B for the proposed text of section 2.105(d)(6)-(8), where the text in paragraph (d)(6) has been moved to paragraph (d)(8).
68. In response to NTIA’s recommendation that we add a subset of the international footnotes that identify spectrum for International Mobile Telecommunications (IMT) to the non-Federal Table, we direct the Chief, Office of Engineering and Technology to maintain a “Mobile Broadband Spectrum in the United States” file on the “Radio Spectrum Allocation” webpage. The FCC Online Allocation Table and Allocation History File are currently available on the “Radio Spectrum Allocation” webpage, i.e., https://www.fcc.gov/engineering-technology/policy-and-rules-division/general/radio-spectrum-allocation.  NTIA recommends that we add references to footnotes 5.295, 5.308A, 5.431B, and 5.434 to the 470608 MHz, 614-698 MHz, 3550-3600 MHz, and 3600-3700 MHz bands, respectively.  NTIA WRC-15 Implementation Recommendations, Attachment 1 – Annex 1.1 and 1.2, at 4, 11.
  We request comment on whether this file meets the public’s needs.
69. Digital Equity and Inclusion.  Finally, the Commission, as part of its continuing effort to advance digital equity for all, Section 1 of the Communications Act of 1934 as amended provides that the FCC “regulat[es] interstate and foreign commerce in communication by wire and radio so as to make [such service] available, so far as possible, to all the people of the United States, without discrimination on the basis of race, color, religion, national origin, or sex.”  47 U.S.C. § 151.
 including people of color, persons with disabilities, persons who live in rural or Tribal areas, and others who are or have been historically underserved, marginalized, or adversely affected by persistent poverty or inequality, invites comment on any equity-related considerations The term “equity” is used here consistent with Executive Order 13985 as the consistent and systematic fair, just, and impartial treatment of all individuals, including individuals who belong to underserved communities that have been denied such treatment, such as Black, Latino, and Indigenous and Native American persons, Asian Americans and Pacific Islanders and other persons of color; members of religious minorities; lesbian, gay, bisexual, transgender, and queer (LGBTQ+) persons; persons with disabilities; persons who live in rural areas; and persons otherwise adversely affected by persistent poverty or inequality.  See Exec. Order No. 13985, 86 Fed. Reg. 7009, Executive Order on Advancing Racial Equity and Support for Underserved Communities Through the Federal Government (January 20, 2021).
 and benefits (if any) that may be associated with the proposals and issues discussed herein.  Specifically, we seek comment on how our proposals may promote or inhibit advances in diversity, equity, inclusion, and accessibility, as well as the scope of the Commission’s relevant legal authority.
VI. PROCEDURAL MATTERS
A. Order
70. Regulatory Flexibility Act.  None of the rule changes discussed in the Order are subject to the notice and comment requirements for rulemaking in the Administrative Procedure Act (APA). See 5 U.S.C. § 553 (herein referred to as the “APA”), and in particular, 5 U.S.C. § 553(b)(B) (allowing for implementation without notice and comment or publication in the Federal Register if good cause exists).
  Section 553(b)(B) of the APA provides exceptions to the notice and comment requirements for rulemakings when, among other things, the agency finds good cause that the notice and comment requirements are “impracticable, unnecessary, or contrary to the public interest” with respect to the rules at issue.  The changes discussed in the Order have no substantive effect on industry or the general public.  Accordingly, we find that it is “unnecessary,” within the meaning of section 553(b)(B) of the APA, to provide notice and an opportunity for public comment before adopting these rule revisions.  Because the rule changes are being adopted without notice and comment, the Regulatory Flexibility Act, 5 U.S.C. §§ 601 et seq., does not apply. See 5 U.S.C. §§ 601(2) (definition of “rule”), 604(a) (requiring a final regulatory flexibility analysis when an agency promulgates a final rule “after being required … to publish a general notice of proposed rulemaking”).

71. Paperwork Reduction Act.  This Order does not contain new or modified information collections subject to the Paperwork Reduction Act of 1995 (PRA), Public Law 104-13 (44 U.S.C. §§ 3501-3520).  In addition, it does not contain any new or modified information collection burden for small business concerns with fewer than 25 employees pursuant to the Small Business Paperwork Relief Act of 2002, Public Law 107-198, see 44 U.S.C. § 3506(c)(4).
72. Congressional Review Act.  The Commission has determined, and the Administrator of the Office of Information and Regulatory Affairs, Office of Management and Budget, concurs, that this rule is “non-major” under the Congressional Review Act, 5 U.S.C. § 804(2).  The Commission will send a copy of this Order to Congress and the Government Accountability office, pursuant to 5 U.S.C. § 801(a)(1)(A).
B. NPRM
73. Paperwork Reduction Analysis.  This document does not contain proposed information collection requirements subject to the Paperwork Reduction Act of 1995, Public Law 104-13.  In addition, therefore, it does not contain any proposed information collection burden for small business concerns with fewer than 25 employees, pursuant to the Small Business Paperwork Relief Act of 2002, Public Law 107-198, see 44 U.S.C. 3506(c)(4).

APPENDIX B

Proposed Rules

The Federal Communications Commission proposes to amend 47 CFR parts 2, 25, 74, 78, 90, 97, and 101 as follows:

PART 2—FREQUENCY ALLOCATIONS AND RADIO TREATY MATTERS; GENERAL RULES AND REGULATIONS

1.	The authority citation for part 2 continues to read as follows:

Authority: 47 U.S.C. 154, 302a, 303, and 336, unless otherwise noted.

2.	Amend section 2.1(c) by: 

i.	Revising the definition for “Coordinated Universal Time (UTC)” and

ii.	Adding definitions for “Frequency band (Band),” “Meteorological aids land station,” and “Meteorological aids mobile station” in alphabetical order.

The revisions and additions read as follows:

§ 2.1   Terms and definitions.

* * * * *

(c) * * *

Coordinated Universal Time (UTC). Time scale, based on the second (SI), as described in Resolution 655 (WRC15). (RR)

* * * * *

Frequency band (Band). A contiguous set of frequencies lying between two specified limiting frequencies.  A frequency band is characterized by two values which define its position in the frequency spectrum, for example, its lower and upper limiting frequencies.

* * * * *

Meteorological aids land station. A station in the meteorological aids service not intended to be used while in motion. (RR)

Meteorological aids mobile station. A station in the meteorological aids service intended to be used while in motion or during halts at unspecified points. (RR)

* * * * *

3.	Amend section 2.102 by adding paragraph (i) to read as follows:

§ 2.102   Assignment of frequencies.

* * * * *

(i) Space research systems intended to operate in deep space may also use the space research service (deep space) allocations, with the same status as those allocations, when the spacecraft is near the Earth, such as during launch, early orbit, flying by the Earth and returning to the Earth.

4.	Amend section 2.105 by revising paragraph (d)(6) and adding paragraphs (d)(7) and (8) to read as follows:

§ 2.105   United States Table of Frequency Allocations.

* * * * *

(d) * * *

(6) The footnote references which appear in the United States Table below the allocated service or services apply to more than one of the allocated services, or to the whole of the allocation concerned.

(7) The footnote references which appear to the right of the name of a service are applicable only to that particular service.

(8) The coordinates of latitude and longitude that are listed in United States, Federal, and non-Federal footnotes are referenced to the North American Datum of 1983 (NAD 83).

5.	Amend section 2.106 by:

a. 	Revising paragraph (a) Allocation Table pages 22, 24, 26 through 30, 32, 45, 47, and 48.

b. 	Revising paragraphs (c)(13) and (23);

c.	Adding paragraph (c)(78);

d.	Revising paragraphs (c)(117), (128), (139), and (224);

e.	Adding paragraph (c)(265);

An Earth station or telecommand station, however, may transmit on the 435-438 MHz segment with a maximum of 611 W effective radiated power (1 kW equivalent isotropically radiated power) without the authorization otherwise required.  The transmitting antenna elevation angle between the lower half-power (−3 dB relative to the peak or antenna bore sight) point and the horizon must always be greater than 10°.

(i) No station may transmit on frequencies in the 60 m band with a radiated power exceeding 15 W (insert value at order stage).  For the purpose of computing EIRP, the transmitter PEP will be multiplied by the antenna gain relative to an isotropic antenna. An isotropic antenna will be presumed to have a gain of 1 (0 dBi).  Licensees must maintain in their station records either the antenna manufacturer's data on the antenna gain or calculations of the antenna gain.

(r) In the bands 17,700 to 19,700 and 24,250 to 25,250 MHz:  Operation of stations using frequencies in these bands is permitted to the extent specified in this paragraph (r).  Licensees, except 24 GHz band licensees, may use either a two-way link or one frequency of a frequency pair for a one-way link and must coordinate proposed operations pursuant to the procedures required in § 101.103.  The use of the band 18.319.3 GHz is limited to grandfathered stations.  Licensees in the fixed-satellite service may require that licensees of grandfathered stations operating in the bands 18.3-19.3 GHz cease operations in accordance with the provisions in section 101.95.  (Note that stations authorized as of September 9, 1983, to use frequencies in the band 17.7-19.7 GHz may, upon proper application, continue to be authorized for such operations, consistent with the above conditions related to the 18.3-19.3 GHz band.)  Applicants for one-way spectrum from 17.7-18.3 GHz for multichannel video programming distribution are governed by paragraph (r)(6) of this section.  Licensees are also allowed to use one-way (unpaired) channels in the 17.7-17.74 GHz sub-band to pair with other channels in the FS portions of the 18 GHz band where, for example, the return pair is already in use and therefore blocked or in TDD systems.  Stations used for MVPD operations in the 17.7-17.8 GHz band must coordinate with the Federal Government before operating in the zones specified in § 1.924(e) of this chapter.

APPENDIX C

Initial Regulatory Flexibility Analysis

1. As required by the Regulatory Flexibility Act of 1980, as amended (RFA), See 5 U.S.C. § 603.  The RFA, 5 U.S.C. §§ 601–612, has been amended by the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA), Pub. L. No. 104-121, Title II, 110 Stat. 857 (1996).
 the Commission has prepared this Initial Regulatory Flexibility Analysis (IRFA) of the possible significant economic impact on a substantial number of small entities by the policies and rules proposed in the WRC-15 Notice of Proposed Rulemaking (WRC15 Notice).  Written public comments are requested on this IRFA.  Comments must be identified as responses to the IRFA and must be filed by the deadlines for comments provided in the WRC-15 Notice.  The Commission will send a copy of the WRC-15 Notice, including this IRFA, to the Chief Counsel for Advocacy of the Small Business Administration (SBA). See 5 U.S.C. § 603(a).
  In addition, the WRC15 Notice and IRFA (or summaries thereof) will be published in the Federal Register. See id.

A. Need for, and Objectives of, the Proposed Rules 
2. In the WRC-15 Notice, the Commission proposes to amend parts 2, 25, 74, 78, 90, 97, and 101 of its rules to implement certain frequency allocation decisions from the World Radiocommunication Conference (Geneva, 2015) (WRC-15) in the Commission’s Table of Frequency Allocations, to make other allocation changes, and to make certain updates to its service rules for service providers and other entities, including those for the amateur radio, aviation, cable television relay, fixed microwave, private land mobile, and satellite services, and for aural broadcast auxiliary and television broadcast auxiliary stations.  These proposals are designed to conform the Commission’s rules to the WRC-15 Final Acts and seek to harmonize U.S. frequency allocations with the decisions made at WRC-15 to the extent this would better meet domestic requirements. 
B. Legal Basis
3. The proposed action is authorized pursuant to sections 1, 4(i), 4(j), 7, 301, 303(c), 303(f), and 303(r) of the Communications Act of 1934, as amended, 47 U.S.C. §§ 151, 154(i), 154(j), 157, 301, 303(c), 303(f), and 303 (r).
C. Description and Estimate of the Number of Small Entities to Which the Proposed Rules Would Apply
4. The RFA directs agencies to provide a description of and, where feasible, an estimate of the number of small entities that may be affected by the proposed rules, if adopted. 5 U.S.C. § 603(b)(3).
  The RFA generally defines the term “small entity” as having the same meaning as the terms “small business,” “small organization,” and “small governmental jurisdiction." 5 U.S.C. § 601(6).
  In addition, the term “small business” has the same meaning as the term “small business concern” under the Small Business Act. 5 U.S.C. § 601(3) (incorporating by reference the definition of “small business concern” in the Small Business Act, 15 U.S.C. § 632). Pursuant to 5 U.S.C. § 601(3),, the statutory definition of a small business applies “unless an agency, after consultation with the Office of Advocacy of the Small Business Administration and after opportunity for public comment, establishes one or more definitions of such term that are appropriate to the activities of the agency and publishes such definition(s) in the Federal Register.”  
  A small business concern is one which:  (1) is independently owned and operated; (2) is not dominant in its field of operation; and (3) satisfies any additional criteria established by the SBA.  15 U.S.C. § 632. 

5. Small Businesses, Small Organizations, and Small Governmental Jurisdictions.  Our actions, over time, may affect small entities that are not easily categorized at present.  We therefore describe, at the outset, three broad groups of small entities that could be directly affected herein. See 5 U.S.C. § 601(3)-(6).
  First, while there are industry specific size standards for small businesses that are used in the regulatory flexibility analysis, from the Small Business Administration’s (SBA) Office of Advocacy, in general a small business is an independent business having fewer than 500 employees. See SBA, Office of Advocacy, Frequently Asked Questions, “What is a small business,” https://cdn.advocacy.sba.gov/wp-content/uploads/2021/11/03093005/Small-Business-FAQ-2021.pdf.  (Nov 2021).
  These types of small businesses represent 99.9% of all businesses in the United States which translates to 32.5 million businesses. Id. 

6. Next, the type of small entity described as a “small organization” is generally “any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.” 5 U.S.C. § 601(4).
  The Internal Revenue Service (IRS) uses a revenue benchmark of $50,000 or less to delineate its annual electronic filing requirements for small exempt organizations. The IRS benchmark is similar to the population of less than 50,000 benchmark in 5 U.S.C § 601(5) that is used to define a small governmental jurisdiction. Therefore, the IRS benchmark has been used to estimate the number of small organizations in this small entity description.  See Annual Electronic Filing Requirement for Small Exempt Organizations — Form 990-N (e-Postcard), "Who must file,"
https://www.irs.gov/charities-non-profits/annual-electronic-filing-requirement-for-small-exempt-organizations-form-990-n-e-postcard.  We note that the IRS data does not provide information on whether a small exempt organization is independently owned and operated or dominant in its field.
  Nationwide, for tax year 2020, there were approximately 447,689 small exempt organizations in the U.S. reporting revenues of $50,000 or less according to the registration and tax data for exempt organizations available from the IRS. See Exempt Organizations Business Master File Extract (EO BMF), “CSV Files by Region,” https://www.irs.gov/charities-non-profits/exempt-organizations-business-master-file-extract-eo-bmf.  The IRS Exempt Organization Business Master File (EO BMF) Extract provides information on all registered tax-exempt/non-profit organizations.  The data utilized for purposes of this description was extracted from the IRS EO BMF data for businesses for the tax year 2020 with revenue less than or equal to $50,000 for Region 1-Northeast Area (58,577), Region 2-Mid-Atlantic and Great Lakes Areas (175,272), and Region 3-Gulf Coast and Pacific Coast Areas (213,840) that includes the continental U.S., Alaska, and Hawaii.  This data does not include information for Puerto Rico.
  
7. Finally, the small entity described as a “small governmental jurisdiction” is defined generally as “governments of cities, counties, towns, townships, villages, school districts, or special districts, with a population of less than fifty thousand.” See 5 U.S.C. § 601(5).
  U.S. Census Bureau data from the 2017 Census of Governments See 13 U.S.C. § 161.  The Census of Governments survey is conducted every five (5) years compiling data for years ending with “2” and “7”.  See also Census of Governments, https://www.census.gov/programs-surveys/cog/about.html. 
 indicate there were 90,075 local governmental jurisdictions consisting of general purpose governments and special purpose governments in the United States. See U.S. Census Bureau, 2017 Census of Governments – Organization Table 2.  Local Governments by Type and State: 2017 [CG1700ORG02], https://www.census.gov/data/tables/2017/econ/gus/2017-governments.html.  Local governmental jurisdictions are made up of general purpose governments (county, municipal and town or township) and special purpose governments (special districts and independent school districts).  See also tbl.2. CG1700ORG02 Table Notes_Local Governments by Type and State_2017. 
  Of this number, there were 36,931 general purpose governments (county, See id. at tbl.5.  County Governments by Population-Size Group and State: 2017 [CG1700ORG05],  https://www.census.gov/data/tables/2017/econ/gus/2017-governments.html.  There were 2,105 county governments with populations less than 50,000.  This category does not include subcounty (municipal and township) governments.  
 municipal, and town or township See id. at tbl.6.  Subcounty General-Purpose Governments by Population-Size Group and State: 2017 [CG1700ORG06], https://www.census.gov/data/tables/2017/econ/gus/2017-governments.html.  There were 18,729 municipal and 16,097 town and township governments with populations less than 50,000. 
) with populations of less than 50,000 and 12,040 special purpose governments—independent school districts See id. at tbl.10.  Elementary and Secondary School Systems by Enrollment-Size Group and State: 2017 [CG1700ORG10], https://www.census.gov/data/tables/2017/econ/gus/2017-governments.html.  There were 12,040 independent school districts with enrollment populations less than 50,000.  See also tbl.4.  Special-Purpose Local Governments by State Census Years 1942 to 2017 [CG1700ORG04], CG1700ORG04 Table Notes_Special Purpose Local Governments by State_Census Years 1942 to 2017.
 with enrollment populations of less than 50,000. While the special purpose governments category also includes local special district governments, the 2017 Census of Governments data does not provide data aggregated based on population size for the special purpose governments category.  Therefore, only data from independent school districts is included in the special purpose governments category.
  Accordingly, based on the 2017 U.S. Census of Governments data, we estimate that at least 48,971 entities fall into the category of “small governmental jurisdictions.” This total is derived from the sum of the number of general purpose governments (county, municipal and town or township) with populations of less than 50,000 (36,931) and the number of special purpose governments - independent school districts with enrollment populations of less than 50,000 (12,040), from the 2017 Census of Governments - Organizations tbls.5, 6 & 10.

8. Amateur Radio Service. Amateur service is a radiocommunication service intended for self-training, intercommunication and technical investigations carried out by amateurs, that is, duly authorized persons interested in radio technique solely with a personal aim and without pecuniary interest. See 47 CFR § 97.3(a)(4).
  Amateur radio service encompasses amateur service, amateur-satellite service and radio amateur civil emergency service. See id. § 97.3(a)(2).
  Licenses are generally held by individuals but can also be held by clubs, associations and other non-profit entities.  Radio Stations See U.S. Census Bureau, 2017 NAICS Definition, “515112 Radio Stations,” https://www.census.gov/naics/?input=515112&year=2017&details=515112.
 is the closest industry with a SBA small business size standard applicable to this service.  The SBA small business size standard for this industry classifies a small entity as one that has $41.5 million or less in annual receipts. See 13 CFR § 121.201, NAICS Code 515112 (as of 10/1/22 NAICS Code 516110). 
  U.S. Census Bureau data for 2017 show that 2,963 firms operated in this industry during that year. See U.S. Census Bureau, 2017 Economic Census of the United States, Selected Sectors: Sales, Value of Shipments, or Revenue Size of Firms for the U.S.: 2017, Table ID: EC1700SIZEREVFIRM, NAICS Code 515112, https://data.census.gov/cedsci/table?y=2017&n=515112&tid=ECNSIZE2017.EC1700SIZEREVFIRM&hidePreview=false.  We note that the US Census Bureau withheld publication of the number of firms that operated for the entire year. 
  Of this number, 1,879 firms operated with revenue of less than $25 million per year. Id.  The available U.S. Census Bureau data does not provide a more precise estimate of the number of firms that meet the SBA size standard.  We note that the U.S. Census Bureau withheld publication of the number of firms that operated with sales/value of shipments/revenue in the individual categories for less than $100,000, and $100,000 to $249,999 to avoid disclosing data for individual companies (see Cell Notes for the sales/value of shipments/revenue in these categories).  Therefore, the number of firms with annual receipts that meet the SBA size standard would be higher that noted herein.  We also note that according to the U.S. Census Bureau glossary, the terms receipts and revenues are used interchangeably, see https://www.census.gov/glossary/#term_ReceiptsRevenueServices.
  Therefore, based on the SBA’s size standard the majority of firms are small entities.  Additionally, according to Commission data as of December 2021, there were approximately 841,734 active licenses for this service. Based on a FCC Universal Licensing System search on December 9, 2021,  https://wireless2.fcc.gov/UlsApp/UlsSearch/searchAdvanced.jsp.  Search parameters: Service Group = All, “Match only the following radio service(s)”, Radio Service = HV, HA; Authorization Type = All; Status = Active.  
  While the majority of these licenses are held by individuals, the Commission estimates that the licenses in this service held by clubs, associations and other non-profit entities are small entities under the SBA small business size standard. 
9. Radio Frequency Equipment Manufacturers (RF Manufacturers).  There are several analogous industries with an SBA small business size standard that are applicable to RF Manufacturers.  These industries are Fixed Microwave Services, Other Communications Equipment Manufacturing, Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing.  A description of these industries and the SBA small business size standards are detailed below.
10. Fixed Microwave Services.  Fixed microwave services include common carrier, See 47 CFR Part 101, Subparts C and I.
 private-operational fixed, See id. Subparts C and H.
 and broadcast auxiliary radio services. Auxiliary Microwave Service is governed by Part 74 of Title 47 of the Commission’s Rules.  See 47 CFR Part 74.  Available to licensees of broadcast stations and to broadcast and cable network entities, broadcast auxiliary microwave stations are used for relaying broadcast television signals from the studio to the transmitter, or between two points such as a main studio and an auxiliary studio.  The service also includes mobile TV pickups, which relay signals from a remote location back to the studio.
  They also include the Upper Microwave Flexible Use Service (UMFUS), See 47 CFR Part 30.
 Millimeter Wave Service (70/80/90 GHz), See 47 CFR Part 101, Subpart Q.
 Local Multipoint Distribution Service (LMDS), See id. Subpart L.
 the Digital Electronic Message Service (DEMS), See id. Subpart G.
 24 GHz Service, See id.
 Multiple Address Systems (MAS), See id. Subpart O.
 and Multichannel Video Distribution and Data Service (MVDDS), See id. Subpart P.
 where in some bands licensees can choose between common carrier and non-common carrier status. See 47 CFR §§ 101.533, 101.1017.
  Wireless Telecommunications Carriers (except Satellite) See U.S. Census Bureau, 2017 NAICS Definition, “517312 Wireless Telecommunications Carriers (except Satellite),” https://www.census.gov/naics/?input=517312&year=2017&details=517312.
 is the closest industry with an SBA small business size standard applicable to these services.  The SBA small size standard for this industry classifies a business as small if it has 1,500 or fewer employees. See 13 CFR § 121.201, NAICS Code 517312 (as of 10/1/22, NAICS Code 517112).
   U.S. Census Bureau data for 2017 show that there were 2,893 firms that operated in this industry for the entire year. See U.S. Census Bureau, 2017 Economic Census of the United States, Employment Size of Firms for the U.S.: 2017, Table ID: EC1700SIZEEMPFIRM, NAICS Code 517312,  https://data.census.gov/cedsci/table?y=2017&n=517312&tid=ECNSIZE2017.EC1700SIZEEMPFIRM&hidePreview=false.  
  Of this number, 2,837 firms employed fewer than 250 employees. Id.  The available U.S. Census Bureau data does not provide a more precise estimate of the number of firms that meet the SBA size standard.
  Thus, under the SBA size standard, the Commission estimates that a majority of fixed microwave service licensees can be considered small.
11. The Commission’s small business size standards with respect to fixed microwave services involve eligibility for bidding credits and installment payments in the auction of licenses for the various frequency bands included in fixed microwave services.  When bidding credits are adopted for the auction of licenses in fixed microwave services frequency bands, such credits may be available to several types of small businesses based average gross revenues (small, very small and entrepreneur) pursuant to the competitive bidding rules adopted in conjunction with the requirements for the auction and/or as identified in Part 101 of the Commission’s rules for the specific fixed microwave services frequency bands. See 47 CFR §§ 101.538(a)(1)-(3), 101.1112(b)-(d), 101.1319(a)(1)-(2), and 101.1429(a)(1)-(3). 
  
12. In frequency bands where licenses were subject to auction, the Commission notes that as a general matter, the number of winning bidders that qualify as small businesses at the close of an auction does not necessarily represent the number of small businesses currently in service.  Further, the Commission does not generally track subsequent business size unless, in the context of assignments or transfers, unjust enrichment issues are implicated.  Additionally, since the Commission does not collect data on the number of employees for licensees providing these services, at this time we are not able to estimate the number of licensees with active licenses that would qualify as small under the SBA’s small business size standard. 
13. Other Communications Equipment Manufacturing.  This industry comprises establishments primarily engaged in manufacturing communications equipment (except telephone apparatus, and radio and television broadcast, and wireless communications equipment). See U.S. Census Bureau, 2017 NAICS Definitions, “334290 Other Communications Equipment Manufacturing,” https://www.census.gov/naics/?input=334290&year=2017&details=334290.
  Examples of such manufacturing include fire detection and alarm systems manufacturing, Intercom systems and equipment manufacturing, and signals (e.g., highway, pedestrian, railway, traffic) manufacturing. Id.
 The SBA small business size standard for this industry classifies firms having 750 or fewer employees as small. See 13 CFR 121.201, NAICS Code 334290.
  For this industry, U.S. Census Bureau data for 2017 shows that 321 firms operated for the entire year. See U.S. Census Bureau, 2017 Economic Census of the United States, Selected Sectors: Employment Size of Firms for the U.S.: 2017, Table ID: EC1700SIZEEMPFIRM, NAICS Code 334290,  https://data.census.gov/cedsci/table?y=2017&n=334290&tid=ECNSIZE2017.EC1700SIZEEMPFIRM&hidePreview=false.  
  Of that number, 310 firms operated with fewer than 250 employees. Id.   The available U.S. Census Bureau data does not provide a more precise estimate of the number of firms that meet the SBA size standard. 
  Based on this data, we conclude that the majority of Other Communications Equipment Manufacturers are small. 
14. Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing. This industry comprises establishments primarily engaged in manufacturing radio and television broadcast and wireless communications equipment. See U.S. Census Bureau, 2017 NAICS Definition, “334220 Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing,” https://www.census.gov/naics/?input=334220&year=2017&details=334220.
  Examples of products made by these establishments are: transmitting and receiving antennas, cable television equipment, GPS equipment, pagers, cellular phones, mobile communications equipment, and radio and television studio and broadcasting equipment. Id.
  The SBA small business size standard for this industry classifies firms having 1,250 employees or less as small. See 13 CFR § 121.201, NAICS Code 334220.
  U.S. Census Bureau data for 2017 show that there were 656 firms in this industry that operated for the entire year. See U.S. Census Bureau, 2017 Economic Census of the United States, Employment Size of Firms for the U.S.: 2017, Table ID: EC1700SIZEEMPFIRM, NAICS Code 334220, https://data.census.gov/cedsci/table?y=2017&n=334220&tid=ECNSIZE2017.EC1700SIZEEMPFIRM&hidePreview=false.  
  Of this number, 624 had fewer than 250 employees. Id.  The available U.S. Census Bureau data does not provide a more precise estimate of the number of firms that meet the SBA size standard.
  Based on this data, we conclude that a majority of manufacturers in this industry are small.  
15. Wireless Telecommunications Carriers (except Satellite). This industry comprises establishments engaged in operating and maintaining switching and transmission facilities to provide communications via the airwaves. See U.S. Census Bureau, 2017 NAICS Definition, “517312 Wireless Telecommunications Carriers (except Satellite),” https://www.census.gov/naics/?input=517312&year=2017&details=517312.
  Establishments in this industry have spectrum licenses and provide services using that spectrum, such as cellular services, paging services, wireless Internet access, and wireless video services. Id.
  The SBA size standard for this industry classifies a business as small if it has 1,500 or fewer employees. See 13 CFR § 121.201, NAICS Code 517312 (as of 10/1/22, NAICS Code 517112).
  U.S. Census Bureau data for 2017 show that there were 2,893 firms in this industry that operated for the entire year. See U.S. Census Bureau, 2017 Economic Census of the United States, Employment Size of Firms for the U.S.: 2017, Table ID: EC1700SIZEEMPFIRM, NAICS Code 517312,  https://data.census.gov/cedsci/table?y=2017&n=517312&tid=ECNSIZE2017.EC1700SIZEEMPFIRM&hidePreview=false.  
  Of that number, 2,837 firms employed fewer than 250 employees. Id.  The available U.S. Census Bureau data does not provide a more precise estimate of the number of firms that meet the SBA size standard. 
  Additionally, based on Commission data in the 2021 Universal Service Monitoring Report, as of December 31, 2020, there were 797 providers that reported they were engaged in the provision of wireless services. Federal-State Joint Board on Universal Service, Universal Service Monitoring Report at 26, Table 1.12 (2021),
https://docs.fcc.gov/public/attachments/DOC-379181A1.pdf.
  Of these providers, the Commission estimates that 715 providers have 1,500 or fewer employees. Id.
  Consequently, using the SBA’s small business size standard, most of these providers can be considered small entities.
D. Description of Projected Reporting, Recordkeeping, and Other Compliance Requirements for Small Entities
16. The WRC-15 Notice proposes and seeks comment regarding the implementation of WRC-15 allocation decisions and other allocation changes.  Further, the WRC-15 Notice proposes to revise footnote US288 by authorizing use of new 12.5 kilohertz and 6.25 kilohertz channels by on-board communication stations operating on spectrum near 457 MHz and 467 MHz in the 450 470 MHz band in the territorial waters of the United States.
17. The WRC-15 Notice does not propose to establish any new reporting or recordkeeping requirements for small entities, nor does it specifically propose any additional operational or implementation costs.  At this time however, the Commission is not in a position to determine whether, if adopted, our proposals and the matters upon which we seek comment will require small entities to hire professionals to comply, and cannot quantify the cost of compliance with the potential rule changes discussed herein.
18. We anticipate the information we receive in comments including, where requested, cost and benefit analyses, will help the Commission identify and evaluate relevant compliance matters for small entities, including compliance costs and other burdens that may result from the proposals and inquiries we make in the WRC-15 Notice.
E. Steps Taken to Minimize Significant Economic Impact on Small Entities, and Significant Alternatives Considered
19. The RFA requires an agency to describe any significant, specifically small business, alternatives that it has considered in reaching its proposed approach, which may include the following four alternatives (among others): “(1) the establishment of differing compliance or reporting requirements or timetables that take into account the resources available to small entities; (2) the clarification, consolidation, or simplification of compliance and reporting requirements under the rule for such small entities; (3) the use of performance rather than design standards; and (4) an exemption from coverage of the rule, or any part thereof, for such small entities.” See 5 U.S.C. § 603(c)(1)–(4).
  
20. The WRC-15 Notice proposal to revise footnote US288 by authorizing operation on new narrower-bandwidth channels for on-board communication stations using spectrum near 457 MHz and 467 MHz in the 450470 MHz band has the potential to cause harmful interference to existing operations of stations in the fixed and land mobile services, which could require some small entities to relocate to other channels to avoid such interference.  This potential for interference and the need for relocation to other channels has been minimized by proposing to: 1) allow use of the existing channels for many of the proposed narrower-bandwidth channels; 2) limit the use of channels 122, 141, and 142 and channel pairs 12/22, 14/24, 102/202, 121/221, 122/222, 141/241, and 142/242 by on-board communication stations to coastal ports and the inland ports of Houston, Baton Rouge, and Portland, and along the waterways and at other ports between these inland ports and the ocean; and 3) require that onboard communication stations do not transmit on these channels while in port and not underway or preparing to get underway.
21. The measures proposed above to minimize the potential for harmful interference to land mobile radio stations operated by small and other entities may be sufficient to avoid causing any harmful interference to such existing stations and thereby avoid imposing a significant economic burden on small entities by requiring relocation to other channels.  In addition, the power authorized for on-board communication stations is sufficiently low enough for us to tentatively find that implementation of these narrowbanding proposals would not have a significant economic impact on a substantial number of small entities in the 450-470 MHz band.  However, we anticipate considering additional measures (e.g., a constant power spectral density consistent with that used in the existing 25 kilohertz channels) to protect land mobile operations from harmful interference in the follow-on service rules proceeding for these on-board communication operations. 
22. The regulatory burdens we have proposed are necessary to implement certain of the frequency allocation decisions from the 2015 World Radiocommunication Conference in the Commission’s Table of Frequency Allocations, to make other frequency allocation decisions, and make certain updates to the Commission’s service rules.  These proposals are designed to conform the Commission’s rules to the WRC-15 Final Acts and seek to harmonize U.S. frequency allocations with the decisions made at WRC-15 to the extent that doing so would better meet domestic requirements.   
23. To assist in the Commission’s evaluation of the economic impact on small entities, as a result of proposed rules in the WRC-15 Notice and to better explore options and alternatives, the Commission seeks public comment as to whether the proposed rules pose any significant economic impacts to small entities and whether any of the costs associated with the WRC-15 Notice requirements can be alleviated for small entities.  The Commission expects to more fully consider the economic impact and alternatives for small entities following the review of comments filed in response to the WRC-15 Notice.
F. Federal Rules that May Duplicate, Overlap, or Conflict with the Proposed Rules
24. None. 


2
