ISS SSTV image 9/12 received by Chertsey Radio Club on Baofeng handheld

Russian cosmonauts are expected to activate Slow Scan Television (SSTV) image transmissions on 145.800 MHz FM from the International Space Station from Saturday, December 28 to Wednesday, January 1.

ARISS will be supporting SSTV transmissions worldwide in memory of cosmonaut Alexei Leonov. Event runs from setup at 1100 GMT on December 28, 2019 until scheduled shutdown at 1820 GMT on January 1, 2020.

Transmissions will be sent on 145.800 MHz FM (5 kHz deviation) in the SSTV mode PD-120. Once received, images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php

ISS SSTV uses a Kenwood TM D710E transceiver which is part of the amateur radio station located in the Russian ISS Service Module.

Please note that SSTV events are dependent on other activities, schedules and crew responsibilities on the ISS and subject to change at any time. You can check for updates regarding planned operation at:

Elín Sigurðardóttir TF2EQ operating TF3YOTA on QO-100

Iceland’s national amateur radio society, the IRA, reports Elín Sigurðardóttir TF2EQ, launched TF3YOTA from TF3IRA’s radio room in Skeljanes on December 19.

First at 14 MHz and when the conditions disappeared it switched to the IRA’s satellite station for communication via the Es’hail-2 / Qatar-Oscar-100 satellite. Ari Þórólfur Jóhannesson TF1A, IRA VHF Manager, assisted Elina and posted, among other things, a fun video of the contacts on Facebook.

The YOTA project began last year (2018) and will be operational in December each year. It is designed to increase young people’s interest in amateur radio. The project is under the auspices of IARU Area 1 and all national amateur radio amateurs in the Region are involved (as well as national members of Regions 2 and 3).

Elín Sigurðardóttir TF2EQ, is the IRA’s youth representative and YOTA project manager together with Árni Frey Rúnarsson, TF8RN. They plan to activate the call sign on as many HF bands (as required) throughout the month, as well as contacts on the OSCAR-100 satellite.

Decoding OPS-SAT’s beacon

ESA is challenging anyone with amateur radio equipment to catch the first signals from OPS-SAT, ESA’s brand new space software laboratory.

On December 17, the 3U CubeSat OPS-SAT will be launched into low-Earth orbit on a Soyuz rocket from Kourou in South America, together with ESA’s Cheops exoplanet-tracker.

Lift-off is scheduled for 08:54:20 GMT on Tuesday, December 17. Deployment will begin 15044.6 seconds later (T+15044.6 seconds), expected to be at 13:05:04 GMT.

15 minutes after satellite deployment, when the UHF antenna and solar array deployment have been confirmed, OPS-SAT will begin transmitting 9600 bps GMSK on 437.200 MHz. The first two passes over Europe are expected on the same evening.

The OPS-SAT flight control team has developed open source software which allows anyone to receive the 437.200 MHz beacon of OPS-SAT and decode it.
