Abstract : Two Marine Corps VHF-FM radio equipments are analyzed to determine the constraints to be placed on their use when tactically deployed. The equipments are the AN/TRC-166, (AN/PRC-25 Manpack Radio with the AN/PCC-1 four- channel multiplex Telegraph-Telephone Terminal Set), and the AN/MRC-109 Vehicle- Mounted Radio Set with either the four-channel AN/VCC-1 (AN/MRC-134) or the eight-channel AN/VCC-2 (AN/MRC-135) multiplex Telegraph-Telephone Terminal Sets. Procedures that incorporate knowledge of terrain, path loss and frequency- distance separation criteria, are developed to assist communicators in the selection of frequencies for operation of AN/MRC-134/135 and AN/TRC-166 VHF-FM radios in the field.
