  • AN/TRC-97

The basic AN/TRC-97 radio system was developed by the Marine Corps during the early-mid 1960's. The first operational application was in South East Asia in 1966. Since then the AN/TRC-97 has been a primary means for providing inter-unit multichannel trunking for USMC and USAF tactical forces. The AN/TRC-97 series radios are all housed in S-308 series shelters (modified S-318 series) and provide a nominal one kilowatt output power with dual space diversity reception for tropostheric forward scatter communication. For line-of-sight operation, the high power amplifier can be bypassed and the one watt output of the intermediate power amplifier (TWT) fed directly to the antenna. 4 Operating frequencies are selected from 1, 200 available ~channe1s~ in the 4. 4 to 5.0 GHz range spaced in 500 kHz increments. It used analog radio and had a 12-channel capability.
