An ARISS Slow Scan TV (SSTV) event is scheduled from the International Space Station (ISS) December 16-19, 2023, on 145.800 MHz FM to celebrate the 40th anniversary of amateur radio in human spaceflight.
The event is slated to begin on Saturday, December 16, at 10:15 GMT for setup and operation and continue until Tuesday, December 19, ending at 18:00 GMT. These times are tentative and are subject to change due to crew availability.
Images will be downlinked at 145.800 MHz +/- 3 kHz for Doppler shift and the expected SSTV mode of operation is PD-120.
Radio enthusiasts participating in the event can post and view images on the ARISS SSTV Gallery at
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.
