Russian cosmonauts on the International Space Station (ISS) are planning to transmit Slow Scan TV (SSTV) images on 145.800 MHz FM probably using the SSTV mode PD-120.

Update June 8: There were no reports of any SSTV transmissions being received.

The transmissions are part of the Moscow Aviation Institute SSTV experiment (MAI-75) and will be made from the amateur radio station RS0ISS in the Russian ISS Service module (Zvezda). This will be the first time the experiment will use the recently installed Kenwood D710GA.

• June 8 Setup and activation 09:45-10:15 GMT, stop about 15:00 GMT*
• June 9 start about 08:35 GMT, stop about 16:15 GMT*

*Dates and times may be subject to change.

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.

ARISS SSTV Event April 11-13

Amateur Radio on the International Space Station (ARISS) logoAn ARISS Slow Scan TV (SSTV) event is scheduled from the International Space Station (ISS) April 11-13 on 145.800 MHz FM to celebrate Cosmonautics Day and Women in Space

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.

ARISS Europe to Perform Special Digital SSTV Experiment

Amateur Radio on the International Space Station (ARISS) logoAmateur Radio on the International Space Station (ARISS) is planning for a special SSTV experiment. ARISS is the group that puts together special amateur radio contacts between students around the globe and crew members with ham radio licenses on the International Space Station (ISS) and develops and operates the amateur radio equipment on ISS.

As part of its ARISS 2.0 initiative, the ARISS International team is expanding its educational and life-long learning opportunities for youth and ham radio operators around the world. ARISS Slow Scan Television (SSTV), which is the transmission of images from ISS using amateur radio, is a very popular ARISS mode of operation. To expand ARISS SSTV capabilities, the ARISS Europe and ARISS USA teams plan to perform special SSTV Experiments using a new SSTV digital coding scheme. For the signal reception, the software “KG-STV” is required, as available on internet.

We kindly request that the amateur radio community refrain from the use of the voice repeater thin this SSTV experiment on February 20, 2022, over Europe.

This is a unique and official ARISS experiment. We kindly request keeping the voice repeater uplink free from other voice transmissions during the experiment time period. Also note that ARISS is temporarily employing the voice repeater to expedite these experiments and make a more permanent, more expansive SSTV capability fully operational on other downlink frequencies.

The first experiment in the series will utilize ARISS approved ground stations in Europe that will transmit these digital SSTV signals. These will be available for all in the ISS footprint when SSTV transmissions occur. The first SSTV experiment is planned for February 20, 2022, between 05:10 UTC and 12:00 UTC for five ISS passes over Europe. Please be aware that this event depends on ARISS IORS radio availabilities and ISS crew support, so last-minute changes may occur.

To promote quick experimental SSTV investigations—to learn and improve–the ARISS team will employ the ISS Kenwood radio in its cross-band repeater mode. The crossband repeater operates on a downlink of 437.800 MHz. Each transmission sequence will consist of 1:40 minute transmission, followed by 1:20 minute pause and will be repeated several times within an ISS pass over Europe.

The used modulation is MSK w/o error correction. For the decoding of the 320 x 240 px image, the software KG-STV is required. The KG-STV software can be downloaded from the following link:
http://amsat-nl.org/wordpress/wp-content/uploads/2022/02/kgstv_ISS.zip

The ZIP file contains the KG-STV program, an installation and setup manual, some images and MP3 audio samples for your first tests as well as links for additional technical information about the KG-STV use.

The members of the ham radio community youth and the public are invited to receive and decode these special SSTV signals.

Experiment reports are welcome and should be uploaded to “sstvtest@amsat-on.be”

More information will be available on the AMSAT-NL.org web page:

ISS SSTV in late December

Amateur Radio on the International Space Station (ARISS) logoThe ARISS team will be supporting Slow Scan TV (SSTV) operations from the International Space Station during the period of December 26-31.

The images will be related to lunar exploration. The transmissions should be available worldwide on 145.800 MHz FM. The planned SSTV mode is PD 120.

Planned start and stop times are currently listed as:
Start – Dec 26 about 18:25 GMT
Stop – Dec 31 about 17:05 GMT

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.

In this video Randy Hall K7AGE shows you how to receive Slow Scan TV (SSTV) images from the International Space Station (ISS).

Several times a year SSTV images are sent from the ISS. In December 2021 from the 26th through the 31st SSTV images will be transmitted.

A simple two-meter amateur radio, or scanner, is able to receive the signal on 145.800 MHz. You can receive the signal using the antenna on an HT, mobile antenna, or a vertical antenna mounted outside.

I show you how to learn when the ISS will be in the range of your station.
Heavens-Above is a good website to use and it will generate a list of passes for your station.

To decode the SSTV signal you will need software on a computer or portable device. I show MMSSTV on my Windows computer decoding the SSTV signal. I also show decoding SSTV on my iPad.
