**NEWS Bulletin** 2023 Year End SSTV Event!

[Michael M]

December 25, 2023 — Amateur Radio on the International Space Station (ARISS) announces a special SSTV experiment to be held this week. The ISS Voice Repeater will be our downlink and several ARISS selected ground stations around the world will serve as SSTV uplink stations. Two special images will be sent on 437.800 MHz using PD120 formating.

This limited experiment will be conducted on several passes over Europe, Australia and the USA between Wednesday Dec. 27 to Saturday Dec. 30, 2023.

We hope radio enthusiasts will download the images and follow along with the event. We appreciate all hams holding off from using the repeater for voice contacts during the event. Watch http://www.ariss.org and ARISS social for pass information and more beginning on Tuesday Dec. 26.

December 27, 2023 0045 UTC - Please check back here for updated status on the passes being supported for this SSTV experiment. ARISS ground stations plan to send two images during each pass on the repeater downlink of 437.800 MHz in PD120 SSTV format. Please do not use the repeater for other contacts during these passes. Please publish reception reports to the http://www.spaceflightsoftware.com/ARISS_SSTV/ gallery. And a special electronic certificate will be offered at http://ariss.pzk.org.pl/sstv/

For those that have not done this in the past, it is quite easy to receive the SSTV images using MMSTV and any outdoor antenna. No special equipment required. http://amsat.org.ar/pass.htm is a great place to get tracking on the ISS.

For some reason they have the repeater still active on the ISS radio they are using. I already have seen lots of complaints about stations trying to
contact the ISS while the SSTV event is on, It disrupts the sstv signal. Please just RX until the event is over. All it takes is a radio tuned to 437.800 and
a jack cord running from the earphone/speaker jack on the radio to the input on a computer running mmstv. They boost the tx power for the sstv and
the picture is for the most part complete before you need a doppler shift. In the past I've recorded the signal and then played it into my computer
and got the picture. Have fun de KN4ZAA

Well it seems like the ISS repeater would have to stay on. I missed the point that it was an experiment.

That's a shame. Looking at what was on the schedule, I could not find an event that would coincide with a communication opportunity in our area. Perhaps I missed something.
