AN/PRC-77 Portable Transceiver
Encyclopedia : A : AN : ANP : AN/PRC-77 Portable Transceiver
AN/PRC-77 Radio Set is a manpack, portable VHF FM transceiver used to provide short-range, two-way radiotelephone voice communication. It can provide secure voice (X-mode) transmission with the TSEC/KY-57. The radio consists of the RT-841 transceiver and minor components. In the Joint Electronics Type Designation System (JETDS), AN/PRC translates to "Army/Navy, Portable Radio, Communication."
The AN/PRC-77 entered service during the Vietnam War (circa 1968) as an upgrade to the earlier AN/PRC-25. Today it has largely been replaced by SINCGARS radios, but the AN/PRC-77 is still capable of interoperating with most VHF radios used by U.S. and allied ground forces (although it is not compatible with the SINCGARS frequency hopping mode).
