Modulator Unit (powered by Dynamotor DM-33-A)

  • BC-456-A (to modulate several transmitters)

Radio Control Box (to control up to four transmitters)

  • BC-451-A

Antenna Relay Unit

The "Type K Command Equipment" had been developed as a modular communications system for Aircraft use (with separate receivers for separate wavebands, separate transmitters, control boxes and accessories) in 1936/37 and has 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.
