Inter-MAI will be transmitting SSTV on April 2 (15:05-18:30 UTC) and April 3 (14:15-18:40 UTC). This is an experiment of the Moscow Aviation Institute so folks in range of Moscow will have the best chance as will folks along the orbits during the indicated time frame.
Additionally, SSTV will be active world wide as part of Cosmonautics Day (April 12). Images will be related to the Interkosmos project (https://en.wikipedia.org/wiki/Interkosmos). Detailed times are still being worked into the schedule and will be update as they become available but the dates will be from April 11-14. This should allow for worldwide reception of images over multiple days.
Both operations will be conducted on the standard 145.800 MHz downlink. Mode is expected to be PD120.
**Update April 4**
Good event from Inter-MAI-75 with all 12 images being captured cleanly by operators.
The next planned activity is an ARISS sponsored activity as part of Cosmonautics Day. Setup is currently scheduled to begin on April 11 at 11:00 UTC and should take around 30 minutes. Transmissions should continue from just after the setup period until April 14 around 18:30 UTC. That is over 3 days of transmissions worldwide so we should capture all 12 images related to the Interkosmos project.
Good luck and 73!
**Update April 11**
Looks like they started a bit later than expected but here is one of the early images that was captured by IW2AGJ over Europe during the pass just before 13:00 UTC.
