File No.:  SES-MOD-20130405-00310
Dear Ms. Lynch:
On April 5, 2013, GCI Communication Corp. (GCI) filed the above-captioned application to 
modify its earth station authorization to add a 3.8-meter antenna to operate in the 3700-4200 MHz 
(space-to-Earth) and 5925-6425 MHz (Earth-to-space) frequency bands.  We dismiss the above-
captioned application as defective without prejudice to re-filing.1
Section 25.112(a)(1) of the Commission’s rules, 47 C.F.R. § 25.112(a)(1), requires the 
Commission to return, as unacceptable for filing, any earth station application that is not 
substantially complete, that contains internal inconsistencies, or that does not substantially 
comply with the Commission’s rules.  We find that GCI’s application is incomplete and internally 
inconsistent for the reason discussed below. 
· GCI did not identify the intended points of communication in item E21of Schedule B to 
Form 312 for Antenna Id 2. 
· GCI lists the EIRP density in item E49 of Schedule B for emission designators 
36M0G7D and 6K72G7D as 50.0 dBW/4kHz.  Based on other information provided by 
GCI elsewhere in its application, we calculate that EIRP density should be 46.4 
dBW/4kHz and 84.2 dBW/4kHz respectively for those emission designators. 2 Moreover 
we note that the total EIRP for all carriers listed in item E40 exceeds the value listed in 
item E48.   Thus, the values provided in the application are inconsistent. 
  
1 If GCI re-files an application identical to the one dismissed, with the exception of supplying the 
corrected information, it need not pay an application fee.  See 47 C.F.R. § 1.1111(d).
2 GCI states in items E48 and E47of the Schedule B that the EIRP per carrier is 86.0 dBW and the 
carrier is 36MHz (75.6dB) and 6kHz (37.8dB) wide respectively.  Accordingly, we convert the Carrier 
EIRP to Carrier EIRP Density/4kHz as follows: 86.0 dBW/carrier - 75.6 dB/carrier + 36 dB/4kHz, which 
equals a maximum EIRP Density/4kHz of 46.4 dBW/4kHz and 86.0 dBW/carrier – 37.8 dB/carrier + 36 
dB/4kHz, which equals a maximum EIRP Density/4kHz of 84.2 dBW/4kHz.

Accordingly, pursuant to Section 25.112(a)(1) of the Commission’s rules, 47 C.F.R. § 
25.112(a)(1), and Section 0.261(a)(4) of the Commission’s rules on delegations of authority, 47 
C.F.R. § 0.261(a)(4), we dismiss the above-captioned application without prejudice to re-filing.
Sincerely,
