    The "Type K Command Radio" had been developed in 1936/37 as a modular communications system for Aircraft use (with separate receivers for separate wavebands, separate transmitters, control boxes and accessories),  and had been tested and improved for military use from 1939 on. In 1940, the U.S. Navy started  installing the equipment as RAT / RAV sets and the U.S. Army Air Corps introduced the equipment as SCR-274-N after May 1940.

    From these sets and it's successors AN/ARC-5 some 1,450,000 sets have been produced. Many of these have been sold as surplus and modified by hams in the postwar years, so sets in original condition are becoming rare.
