## Abstract

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.

## Claims

### Claim 1

A method for broadcasting audio and slow scan TV signals simultaneously from the same AM broadcast station, comprising: AM broadcast station is transmitting the audio and slow scan TV signals at the same time over the air, wherein the audio and slow scan TV signals to be transmitted over the same 15 KHz Wide channel on the AM band within the bandwidth that is allowed by the Federal Communication Commission that regulates broadcast communications, wherein for AM Video an AM Analog Radio with an Analog tuner can be directly tuned to 692 KHz; An Analog Radio with Digital tuner can be tuned to 690 KHz for the video, which would be 10 KHz down from the main audio carrier on the AM receiver, and using any ordinary broadcast AM receiver by listening the Fax like Beeps, before plugging in any stand alone Slow Scan TV Converter in the Headphone jack of the AM receiver being used for the video, the same AM receiver used to receive the video, can tune in the audio when tuned to 700 kHz.
