The initial model BC-348, the B, debuted in1938. It was a 28 VDC version of the Signal Corps’ BC-224 receiver and was powered by an internal dynamotor. The early models tuned from 1.5 to 18 MHz in six bands. The E and later versions added 200–500 kHz coverage to one band and compressed the 1.5–18 MHz range into the remaining fivebands. The model H, manufactured by Chicago’s Belmont Radio Corporation, was a nine-tube, single-conversion superhet; WW II.
The BC-348-J, N, and Q used single-ended tubes and were manufactured by Wells-Gardner. They were also eight-tube sets, having deleted the 991 VR tube from the lineup used in earlier models; WW II.
