ArcticSat-1 RS74S. My first SSTV reception off of this satellite. I love this stuff. Not bad for an HT with a standard antenna.

Captured a partial SSTV image from UmKA-1 (RS40S). All kinds of cool stuff floating in the ether if you know where to look.

No matter how often I do it, there is still something incredible about sending and receiving signals to and from an object that is 257 miles above me moving at 17,147 mph. I love amateur radio!
