PHONOGRAPH RECORDS RADIO PROGRAM (Dec, 1930)
PHONOGRAPH RECORDS RADIO PROGRAM
You can make a phonographic record of your own voice or record your favorite radio program through an attachment on a new combination radio and phonograph. The attachment does not interfere with the ordinary use of the instrument for playing a record or program.
For record making, a microphone picks up voices and transmits them to a blank record through an electric “pick-up” similar to the reproducing arm of a standard electrified phonograph.
