SSTV – Slow Scan Television


I got started in Slow Scan TV (or SSTV) when I first heard about it back in 1995. I began by using a shortwave radio and a Commodore 64 computer to decode the images. I was hooked after I received my first image off the air.

As can be seen elsewhere on this site, I’ve been very active in SSTV for many years.

I operate a Live 24/7 SSTV Cam that copies images on 14.230 during the day, and on 7.171 in the evenings. I also have a cam on 14.233 for EasyPal digital image reception. All of which can be viewed live here.

Most of my received images are acquired on the HF frequencies. But not all of them. Over the years I have gradually upgraded my SSTV abilities to include Amateur Satellite operations.

SSTV on the International Space Station

You heard that right! The International Space Station has SSTV equipment on board. Not only that! They transmit SSTV pictures on 145.8 mhz in the Amateur Radio 2 Meter Band. SSTV on the ISS is reserved for special occasions. Both the Russian and US astronauts participate.

Special thanks to my SSTV buddy Brad, KO6KL and AMSAT’s Clint Bradford (K6LCS) for sending me a heads up about this event. I set my satellite station to track the ISS exclusively, in an attempt to capture any images that could be heard. There were several good passes, and the images shown above are the best of the lot this time around. I have the San Bernardino mountains to my north. Once the satellite, or the ISS in this case, gets behind the mountains, the pass is over as there is no longer any reception.

The best source for SSTV information is the WA9TT SSTV Website run by Larry, in Appleton, Wisconsin.

I read somewhere that at least one of the newly lauched satellites will support SSTV once it’s educational mission has been fulfilled, and the satellite can be released for amateur SSTV use. Something to look forward to!
