AN/PRC-10
(Redirected from AN/PRC-9)
The AN/PRC-10 is an American VHF portable radio transceiver, introduced in 1951[1] as a replacement for the wartime SCR-300 set. The AN/PRC-8 and AN/PRC-9 sets are basically the same but cover lower frequency bands. It remained in service with the American military until the mid 1960s when it was replaced by the transistorized AN/PRC-25 set.
