SSTV TruckCam, UK

August 11, 2010

Slow-scan television (SSTV) is a picture transmission method used mainly by amateur radio operators, to transmit and receive static pictures via radio in monochrome or color.

TruckCam

SSTV was used to transmit images of the far side of the Moon from Luna 3.  Commercial systems appeared in the United States in 1970, after the FCC had legalized the use of SSTV for advanced level amateur radio operators in 1968.

SSTV originally required quite a bit of specialized equipment, but a modern system, having gained ground since the early 1990s, uses a personal computer and special software in place of much of the custom equipment. The sound card of a PC, with special processing software, acts as a modem. The computer screen provides the output. A small digital camera or digital photos provide the input.

Images taken from inside the truck updated every 30 seconds when on the road. Live from around the UK.   Monday to Friday from 4am GMT.  This is a mobile internet connection so sometimes when connection is lost the image will not update until  a good connection resumes.   Same with the Tracking, when not in range of another APRS station the tracking will stop.  APRS location data from ham radio on 144.800Mhz.
