Image Communication on Short Waves (2011)
- vel0city 7y agoI've been fascinated by SSTV in the amateur bands, but I am never quite certain which frequencies to listen in on to try and hear some activity. What frequencies are the most common to catch some interesting SSTV transmissions? Obviously things like the space station ARISS on 145.800 is neat to tune into as its overhead, but I'm looking for more.

- vel0city 7y agoAwesome, tuned in on some WebSDR stations and immediately found lots of traffic. Time to set up a decent HF antenna and see what I can see from my QTH. Any other frequencies with SSTV traffic common? Thanks!
- lb1lf 7y agoOnce you've heard the warble of SSTV, it is quite simple to recognize - I hear it all the time around 3850 and 7175kHz or so; this is in IARU R1. Other regions may have other activity centres.
- curiousfab 7y agoGood memories of the late 90s - decoding SSTV images on 14 MHz on my 386DX40 with "JVfax" (DOS - now also available for Windows http://www.jvcomm.de/index_e.html http://www.jvcomm.de/index_e.html). All you needed was a little converter that connected to the serial port, no sound card! Back then it was kind of a big deal to see "live" pictures from all over the world, building up line by line. Today SSTV is not much used any more on the shortwave bands but the ISS regularly transmits SSTV pictures and it's still fascinating.
