Satellite operators have a short window this week to listen for a special transmission from UmKA-1, also known as RS40S, tied to International Moon Day. Amateur Radio Daily reports that the satellite is scheduled to alternate special audio clips and slow-scan television (SSTV) imagery through July 26.
The announced schedule includes SSTV-and-audio days on July 20, 23, and 25, followed by a short technical broadcast on July 26. The SSTV mode is listed as Robot 36, so this is a timely opportunity for operators who already have satellite-receive capability—or who want to see what can be decoded from a pass.
This is not a general operating event announcement from AVRC; it is a source-linked listening opportunity. Check the current satellite pass information and the original report before planning an attempt.
