Federal Communications Commission Washington, D.C. 20554 July 26. 2007 Joan M. Griffin Kelley Drye & Warren LLP 3050 K Street, NW. Suite 400 Washington DC 20007 Re: Call Sign E990143 File No. SES—MFS—20070530—00731 Dear Ms. Griffin: On May 30, 2007, Comtech Mobile Datacom Corporation (CMDC) filed the above—captioned application seeking authority to modify its blanket license for L—band terminals operating in the Mobile Satellite Service (MSS). The blanket license authorizes CMDC to communicate with the Canadian MSAT—1 satellite in certain portions of the L—Band. In its modification application, CMDC seeks, among other things, authority to operate on frequency band segments in the L—band that are not in its authorization. We request that CMDC provide the following information, by amendment, so that we may continue to process the application. Item S8(f) of Schedule S requires satellite applicants to provide an antenna gain contour diagram in .gxt format for each satellite beam, and to identify which .gxt file is associated with which beam. For MSAT— 1, Beam IDs LE5S and LR5, CMDC lists "MSAT—1—Tx—South.gxt" and "MSAT—1 —Rx—South.gxt" in response to item S8(f). In both of these .gxt gain contour files, however, the Beam ID is identified as "TLS5." Similarly, for MSAT—1 Beam IDs OMNIE and OMNIR, CMDC lists "MSAT—1 Omni—E.gxt" and "MSAT—1 Omni—R.gxt" in response to item S8(f). In both of these .gxt gain contour files, however, the Beam ID is identified as "?". In addition, CMDC lists long_nom=—111.10, and p=—111.1000;0.0000 in both of these .gxt files. Further, in the "MSAT—1 Omni—R.gxt" file, CMDC lists emi_rep=E rather than emi_rep=R. These values appear to be typographical errors. As a result of errors, we are unable to compare the .gxt files for these beams with the information provided for these beams in Schedule S, and therefore, we are unable to determine whether the beams comply with the Commission‘s rules. Please provide the correct beam identifications for these beams. CMDC should submit the requested information within thirty calendar days from the date of this letter. Failure to submit the requested information will result in dismissal of the application pursuant to Section 25.112(c) of the Commission‘s rules. Sincerely, Scott A. Kotler Chief, Systems Analysis Branch Satellite Division International Bureau
