The event is slated to begin on April 11 at 17:25 UTC for setup and operation and continue until April 13 ending at 12:00 UTC. These times are tentative and are subject to change due to crew availability.
Images will be downlinked at 145.8 MHz +/- 3 kHz for Doppler shift and the expected SSTV mode of operation is PD-120.
The theme for this event will be celebrating Cosmonautics Day and Women in Space.
Radio enthusiasts participating in the event can post and view images on the ARISS SSTV Gallery at https://www.spaceflightsoftware.com/ARISS_SSTV/
The signal should be receivable even on a handheld with a 1/4 wave whip. If your rig has selectable FM filters try the wider filter for 25 kHz channel spacing.
