These little radios were used all during Viet-Nam and many years after. They were called the Squad radio or Helmet radio set when combined with the PRR-9 radio receiver. Made to operate on frequencies from about 47 MHz up to about 53 MHz on crystal controlled channels at two different power setting. If unit was never issued it is set to operate on 51 MHz. If issued may be on any frequency. Can net with late gear like PRC-25, -77 and VRC vehicle sets as well as older stuff like the PRC 6, 8, 9 and 10 series. Battey was normally a 15 volt unit but can easily be run on two 9 volts in series. Battery life is very good. There were two styles of battey box. Units are operational and checked prior to shipping. Physical condition is exc to unissued or depot rebuild. You can see the color differences. The center unit has the early color while the others have the CARC paint. This item is for a single radio set in rebuilt and or unissued condition. You can specify the type of battery box (open or solid casestyle) and will try for color, early or late style.
