EspañolBC-348
The 'B-348' is a compact American made communications receiver, which was mass-produced during World War II for the U.S. Army Air Force. 
Installed in almost all USAAF (and many USN, British and Canadian) multi-engined transports and bombers used during the fifteen year period from before World War II through the Korean War, BC-348 radio receivers were easy to operate and reliable. Designed as HF receivers for use in heavy aircraft (B17, B24, B29 etc.), they were generally paired with an ART 13 transmitter. They were also used in some ground installations. [1]The BC-348 series ran to several variations during its long production history, which included the BC-224. More than 100,000 of these receivers were produced: 80 percent of them by Belmont Radio and Wells Gardner in Chicago; the balance by RCA and Stromberg-Carlson, in the New York/New Jersey area. It has been suggested that BC-348 receivers were copied and manufactured by the U.S.S.R. during War II by the Russian Vefon Works.[2]
Enola Gay, the B-29 Superfortress bomber that dropped "Little Boy", the first atomic bomb on Hiroshima, Japan was equipped with the ART 13 transmitter and BC-348 receiver combination.[3] Today, many examples of the BC-348 are restored and operated by vintage and miitary amateur radio enthusiasts. [4]
The BC-224-A, -B, -C, and -D; and the BC-348-B, and -C, tuned 1.5-18 MHz in six bands. The Signal Corps had the receiver design modified to add a 200-500 KHz band and compress the 1.5-18 MHz coverage into the remaining five bands. This modified design became the BC-224-E and the BC-348-E. The 200-500 KHz and 1.5-18 MHz tuning range remained constant for subsequent production of all models.[2]
