The BC-342 was a World War II U.S. Army Signal Corps high frequency radio receiver.
First designed at Fort Monmouth, New Jersey by the U.S. Army Signal Corps, it was built by various manufacturers including RCA.
Many of the later units that are encountered today were manufactured by the Farnsworth Television and Radio Corporation of Fort Wayne, Indiana.
Heavy chassis design was employed to minimize drift and oscillator instability due to temperature changes and vibration.
[5][6] The BC-312 was similar to the BC-342 but was designed to be directly powered by DC battery supply or dynamotor.
