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 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.

The SSTV system in the Service Module will be activated to attempt to verify a replacement piece of hardware during the period of Oct 27 until Nov 01.

The system will be off around the required period of no transmissions during the planned EVA on Oct 31. Images will be transmitted on 145.800 MHz and in the typical PD120 format.

There are 2 windows for testing, separated by an EVA:
Fri Oct 27 at 12:15 GMT – Sun Oct 29 at 18:50 GMT
Tue Oct 31 at 10:05 GMT – Wed Nov 01 at 18:10 GMT

Your images can be posted to the Gallery at https://www.spaceflightsoftware.com/ARISS_SSTV/index.php

Since this is a test of replacement components of the system, there still may be unexpected outages or issues.

The signal should be receivable 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.

UPDATE: Event to be Rescheduled. R4UAB reports that from October 3, 2023 to October 5, 2023 images will be transmitted from the International Space Station via the SSTV protocol as part of the “About Gagarin from Space” experiment. The topic of the program is the first artificial Earth satellite, amateur radio satellites, school satellites.

SSTV images will be transmitted on 145.800 MHz using a Kenwood TM-D710 transceiver. They are expected to use the PD-120 SSTV format.

The scheduled start of transmission is October 03, 2023 at approximately 14:40 UTC. The end of transmission is scheduled at October 05, 2023 at approximately 18:15 UTC. The date and time may change.

The “Russia ISS SSTV” diploma is awarded to radio amateurs (observers) for receiving SSTV (slow-scan television) broadcasts from aboard the International Space Station (ISS) as part of the space experiment (SE) “About Gagarin from Space.” To receive the “Russia ISS SSTV” Diploma, one must receive and decode three images transmitted over a radio channel from on board the ISS using the SSTV protocol only on the days of the SE . Each image must be at least 90% complete and of acceptable quality. Information on earning the certificate is available at https://r4uab.ru/diplom-iss-sstv/

AMSAT Argentina is also offering a diploma for reception of ISS SSTV images. Learn more at http://amsat.org.ar/?f=9
