WWII U.S. Army Signal Corps BC-771 Frequency Meter – General Electric

Original WWII U.S. Army Signal Corps BC-771 Frequency Meter manufactured by General Electric, Schenectady, New York under 1942 contract. Used for precision frequency measurement, calibration, and maintenance of military radio and radar systems. This example retains its original front panel, controls, data plate, and a remarkably complete internal chassis with original tubes, shielded components, coils, and calibration assemblies. A highly desirable piece of early military test equipment from the formative years of radar and radio communications.
