3.7 UHF RADIO, AN/ARC-164(V) (COM 2).
Receiver-Transmitter Radio RT-1167C/ARC-164(V) is an airborne, ultra-high frequency (UHF), AM and FM, radio transmitting-receiving set. It contains a multi channel, electronically tunable main transmitter and receiver, and a .xed-tuned guard receiver. The main transceiver operates on any one of 7,000 channels, spaced in 0.025 MHz units in the 225.000 to 399.975 MHz UHF military band. The guard receiver is tunable in the 238.000 to 248.000 MHz fre-quency range with crystal replacement and realignment (usually 243.000 MHz). The radio set is primarily used for voice communications. HAVE QUICK is an antijamming mode which uses a frequency hopping scheme to change channels many times per second. Because the HQ mode depends on a precise time-of-day, both HQ radios must have synchronized clocks. The UHF radio is referred to as COM 2, corresponding to its position on the ICS mode select switch.
