Radio Set - A medium range, high quality 1 KW PEP SSB transmitting and receiving system operating over a freq range of 2-30 MHz. By incorporating SSB capability, this system achieves a two-to-one advantage over AM units in efficient radio spectrum use. The modified AN/GRC-26D will transmit and receive SSB, AM, CW, and FSK, as well as AM/FSK or SSB/VFT (voice freq telegraph) on a multiplexed basis. An increase in the range of comm from a few hundred miles in the premodified 450 watt AM mode is obtained and an effective increase in power with suppresed carrier which is comparable in performance to the 8 KW AM system.
