The AN/PRC 77 Radio Set is made in a portable manpack format. It is a portable VHF FM combat-net radio transceiver manufactured by Associated Industries. It is used used to provide short-range, two-way radio-telephone voice communication over 920 channels across two bands using 50 kHz steps.
The device entered service in 1968 during the Vietnam War as an upgrade to the earlier AN/PRC 25.
In the Joint Electronics Type Designation System (JETDS), AN/PRC translates to "Army/Navy, Portable, Radio, Communication."
It's electronics differ from its predecessor, the AN/PRC 25, mainly due to the fact that its final power amplifier stage is made up of solid state components (integrated circuits and transistors) and does not use vacuum tubes/valves.
The AN/PRC 77 consists of the RT-841 transceiver, plus some other minor components. It is compatible with Norway's Multi Rolle Radio and can provide secure communication with the TSEC/KY-57 voice encryption device, but is not compatible with the SINCGARS class frequency hopping mode.
