By Memorandum Opinion and Order, 10 FCCRcd 12143(1995) ("OrderI'~, the Commission partially granted reconsideration, rescinded Public Notice I and the initial improvement ranking factors of stations that had petitioned to migrate to the Expanded Band I and solicited comments on proposed technical procedures to calculate. revised improvement ranking factors and generate a new allotment plan. In Comments in Response to Reconsideration ofImplementation ofthe AM Expanded Band and Allotment Plan, 11 FCC Rcd 12444 (1996) ("OrderII'~,the CoII¥Dission denied alll]loc\ifications proposed in comments.filed in response to Order I. adopted the Order I procedures and closed the June. 30, 1993-Aengineering'database to further revision.Concurren~y,the Mass Media Bureau released Public Notice, Mass Media Bureau Announces RevisedExpanded AM Broadcast Band Improvement Factors and Allotment Plan, DA 96-408 (released March 22,1996) ("Public Notice If'), which listed the improvement factor or"each station that had petitioned to migrate to the Expanded Band and announced an eighty-seven station allotment plan (the "Second Allotment Plan") for new assigrunents in the Expanded Band. " '" Initial improvement factor rankings appeared in a December 3, 1993 Public Notice. Stations will be allotted channels on the basis of their calculated improvement factor rankings. See 47 C.F.R. § 73.30. Each station's improvement factor is represented by a ratio of the area of interference caused to all other stations divided by the migrator's interference-free service area. The larger the improvement factor, the greater the reduction in existing band interference that would result from the relocation of the migrating station to the Expanded Band. 3361 Federal' Communications Commission FCC 97-68 2.. Now before the Commission are eight timely-filed-petitions for reconsideration of Order II and Public Notice 11. 2 For the reasons set forth below, we grant in'part the petition of WGNY,.rescind the Second Allotment Plan, and modify the frequency preclusion program, one of two primary programs used to generate the allotment plan, to follow the federal travelers information station ("TIS") frequency preclusion standards specified in Order I. On our own motion we conform the revised plan to Region 2 treaty requirements and eliminate software coding errors in the frequency preclusion and allotment plan programs. We also clarify the second harmonic interference standard which has been applied in this proceeding. We deny the other petitions for reconsideration. The Mass Media Bureau is concurrently reissuing the Expanded Band allotment plan (the "Third Allotment Plan") based on the changes adopted in this Order. THE WGNY PETITION 3. The Second Harmonic Interference Standard. Stations operating on 810, 820, 830, 840, and 850 kHz have the potential to cause interference to Expanded Band stations operating at twice the carrier frequency ,of the existing band stations, i.e., to Expande\i Band stations operating on 1620, 1640, 1660, 1680, and 1700 kHz. Such second harmonic interference is caused by the generation ofthe ,second harmonic. ofthe lower frequency within the radio receiver. Section 73.182 restricts·thelocatiort of the transmission facilities of 540 - 800 kHz stations in order, to prevent second harmonic interference to .existing band stations. Sunrise Broadcasting of New York, Inc.; licensee ofWGNY; Newburgh, New York ("WQNY")rnaintains that the COIDnlissiOn did not follow ·the standard annoUnced in Order I to calculate harmonic interference betWeen existing and Expanded Band stations. Moreover, WGNYcontendsthat we should . reconsider the stated Order istandard which provides significantly greater harrnoni<: interference pr()tection than the standard set forth in the Commission'sru1f~s.It argues.that the rule,itself, is too preclusive and urges the Commission to "revisit" this issue to ensure that the fmal a,llotment plan achieves the greatest'possible interference reductions among licensed stations. . 4. In Order 1, we proposed to preclude Expanded Band assignments which would result in prohibited second haitnonic overlap,asdeterrninedinaccordance with 47 ().f·R §7~·182(s). See Order I, 10 FCC Rcdat 12148; .However, Order I misstates this rule as prohibiting
