The AN/PRC-77 entered service in 1968 during the Vietnam War as an upgrade to the earlier AN/PRC-25.It differs from its predecessor mainly in that the PRC-77's final power amplifier stage is made with a transistor, eliminating the only vacuum tube in the PRC-25, as well as the DC-DC voltage converter used to create the high plate voltage for the tube from the 15 V battery.
There is an optional handset H-33*/PT that can be connected to the AN/PRC-6 by a 5 ft (1.5 m) cable. The RT-196 can be carried over the shoulder using a provided web sling. Rated power output is about 250 mW. The range is about one mile (1.5 km), but much less in jungle. [8] [9]
A portable battery-powered AM/FM broadcast receiver, used to listen to audio broadcast by local radio stations. A modern communications receiver, used in two-way radio communication stations to talk with remote locations by shortwave radio.
The frequency range used by most early radio systems, 25–50 MHz (vhf "low band") is particularly susceptible to the problem of electrical noise. This plus the need for more channels led to the eventual expansion of two-way radio communications into the VHF "high band" (150–174 MHz) and UHF (450–470 MHz).
