A system for AM broadcasting, and listing to audio, as well as, viewing
slow scan pictures, by using an ordinary AM receiver and a slow scan
video converter. The slow scan can be an AM picture, such as, robot 36,
or a FM picture in the AM band, using the FAST FM MODE of a slow scan
converter, like the KENWOOD VC-H1. A transmitter, like the AM-88 NORTH
COUNTRY RADIO, can broadcast in AM or FM mode on the AM band.Because of
frequency differences between the audio and video, and if desired,
modulation differences between the audio and video, there is no
interference between the audio and video on the AM service.A diplexer and
an antenna tuner enable both signals to be sent out from the same
antenna.
