Using a signal generator HP 606A 15 mc, transmit a 1944 SX-28A built. The audio begins with the old radio (MP3) downloaded from the site of public domain files from the Internet. After playing in a laptop PC with Windows Media Player. The signal is sent to an RCA audio cable to an amplifier to drive the Yamaha generator modulation signal and finally to the antenna. You hear President Franklin Roosevelt addresses Congress Dec. 8, 1941 (approximately 4.5 minutes) before a cutto see popular shows WW2 Armed Forces Radio Service, "GI Jive." Enjoy the radio almost exactly as I had heard of this receptor with its wide range of PM-23 speakers.
