GENnNERAL DYNAMICsS CA4 Systems June 10, 2013 Federal Aviation Administration Office of Spectrum Policy and Management, ASR—1 800 Independence Avenue S.W. Washington, DC 20591 Dear Sir/Madam: This is to inform you that General Dynamics C4 Systems (GDC4S) will be submitting applications for FCC certification under 47 CFR Part 87 for two (2) Air Traffic Control VHF Radio transmitters, also referred to as the CM—350 (V2) VDT (High Power) and CM—300 (V2) VDT (Low Power). This equipment is being certified under the current FAA Next Generation Air—Ground Communications (NEXCOM) Segment 2 program, Contract # DTFAWA—12—C— 00040. These FCC certification applications will be processed through Intertek Testing Services, NA Inc. (ITS) which is a Telecommunications Certification Body (TCB) for the FCC. The applicant and manufacturer are identified as: General Dynamics C4 Systems 8220 E. Roosevelt St. Scottsdale, Az 85257 These VHF transmitters are part of a rack mounted VHF transmitter and receiver system. The CM—350 (V2) VDT is capable of transmitting at a maximum RF output power level of 35W. The CM—300 (V2) VDT is capable of transmitting at a maximum RF output power level of 12W. Additional details including emission types, operational frequency band, and receiver characteristics are provided in the attached data sheet. GDC4S does not supply the antennas for use with these Radios. Please contact me if you have any questions or if additional information is required. My email address is Gil.Estrella@gdc4s.com and phone number (480) 441—3725. Sincerely, ald Sb Gil 0.
