Fast scan is a wide bandwidth rf signal (Wider than the 2 Meter band) similar to broadcast TV. 1997: SC-4 SSTV-PC-Scanconverter designed by DL2RZ with fully multitasking Windows 95/98 Software "Charly 4.0" written by DJ6PS 2002: Version 1.06 of MMSSTV by Makoto Mori JE3HHT, First program utilizing a PC Sound Cardħ Slow Scan vs Fast Scan Slow scan is sending an audio signal with the information embedded. 1993: SC-3 SSTV & FAX-PC-Scanconverter with DK7BO-DOS-Software.Ħ History of SSTV 1995: First true Windows SSTV-Program "Charly" developed by DJ6PS for the SC-3 PC-Scanconverter.
Became a difficult to reach standard for all software developers. This unique system did not only allow to easily generate live sstv pictures with any standard black&white camera but also allowed reception of high resolution fax and wefax images from polar orbiting and geostationary weather satellites and to convert fax to sstv and vice versa.ĥ History of SSTV 1986: High resolution color sstv & fax scanconverter SC-2, allowed higher than tv-quality images (512 pixels per line) to be transmitted via ham radio. Pictures were stored on tape recorders and on Polaroid pictures.Ĥ History of SSTV 1981: First combined high-resolution color sstv and fax scanconverter SC-1. Flying Spot scanners Were used to “look at pictures” and send signals to Tape Recorders. This allowed an image to be painted on the screen over a period of a few seconds. SSTV started out with surplus radar display tubes with very long persistence ("P7") phosphors.
