A genuine issued U.S. Vietnam War era AN/PRC-90 airman rescue set/survival radio. The radios would operate on 243 & 282.3 MHz AM and included a beacon mode, and a tone generator to allow the sending of Morse Code. This unit is untested, the push buttons appear to click nicely and toggle wheels scroll firmly. It comes with the fabric carry strap with headphone pouch, dated 1972.
