D.J. Circa 1931

Washington, D.C., 1931. "Man with portable radio receiver and phonograph." Who seems to be using the amplifier to play a record into a microphone. Note handy "Radio Spectrum" chart. Harris & Ewing glass negative.

  1. This is a system built for the Federal Radio Commission that allowed it to record radio stations off the air. According to a press release issued at the time, "the apparatus is a portable disc equipment consisting of two motor-driven turntables, a recording amplifier, a microphone, radio receiver and a loudspeaker. Pre-grooved blank disc records are placed upon each of the turntables, and when in operation, with sound being recorded as it emanates from a loudspeaker. The records operate continuously and automatically change from one to the other. This device is expected to help the Federal Radio Commission in settling any problems of programs on the air, having had to use stenographic reports until now."
