Good memories of the late 90s - decoding SSTV images on 14 MHz on my 386DX40 with "JVfax" (DOS - now also available for Windows <a href="http://www.jvcomm.de/index_e.html" rel="nofollow">http://www.jvcomm.de/index_e.html</a>). All you needed was a little converter that connected to the serial port, no sound card!<p>Back then it was kind of a big deal to see "live" pictures from all over the world, building up line by line.<p>Today SSTV is not much used any more on the shortwave bands but the ISS regularly transmits SSTV pictures and it's still fascinating.
