ARISS Russia is planning a special Slow Scan Television (SSTV) event from the International Space Station in celebration of Cosmonautics Day.
The transmissions began on April 11 at 11:30 UTC and run through April 14 ending at 18:20 UTC.
The ISS is transmitting on 145.800 MHz FM. The SSTV signal is using PD120. I recommend you record the passes for decoding in case a live capture has issues decoding. (You may capture two image transmissions during one pass as each one takes 120 seconds.)
When the ISS is nearly overhead, an HT should pickup the transmission. Just angle the radio a bit.
Visit the N2YO.com website to review 10 day predictions (A blue button on the right side). Please note that you will want to choose “all passes” as they initially list only visible ones.
Review images that others have already captured for this event.
