Looks like the folks at MAI will have an experiment run right at the end of July. Crew timeline shows activation of the SSTV system beginning with setup starting at 16:00 UTC on July 30. The system will be powered down that same day at 19:30 UTC. The next day (July 31), the system will be again active from 13:25-19:15 UTC. Downlink is presumed to be on the traditional 145.80 MHz frequency. Mode will likely be PD120 but not officially known at this time.
