Vietnam War PRC-77 radio Transmitter AN/PRC-77


This item is out of stock
 I upgraded the radio with a double A battery with cost $75.00.  The radio shows it has power.  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 its final power amplifier stage is made up of solid state components and not vacuum tubes like the PRC-25. Also the PRC-77 has the ability to use voice encryption devices, while the PRC-25 could not. These include the TSEC/KY-38 NESTOR equipment used in Vietnam and the later KY-57 VINSON family. Problems were encountered in Vietnam with the combination as described in the NESTOR article.
