How does slow scan TV work?

SSTV uses frequency modulation, in which every different value of brightness in the image gets a different audio frequency. In other words, the signal frequency shifts up or down to designate brighter or darker pixels, respectively.

What is Slow Scan Mode?

Overview. Use this function when you wish to scan thin originals using the automatic document feeder. It helps prevent thin originals from misfeeding. When slow scan mode is selected, 2-sided scanning is not possible.

How do I transmit SSTV?

All you need to do to receive SSTV pictures direct from the space station is to connect the audio output of a scanner or amateur radio transceiver via a simple interface to the soundcard on a Windows PC or an Apple iOS device, and tune in to 145.800 MHz FM.
