ARISS experiment to test KG-STV on Feb 20 (Clear channel requested)

 Received the following news release from ARISS. Please provide a clear channel during the Feb 20th experimentation tests. Downlink will be on 437.800 MHz plus and minus Doppler.


FOR IMMEDIATE RELEASE

ARISS Europe to Perform Special Digital SSTV Experiment

February 15, 2022—Amateur 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 during this SSTV experiment on 20th of February 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 20 February 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: "https://amsat-nl.org/?page_id=568"

MAI-75 Oct 9 and 10

The Initial MAI-75 SSTV times from ISS are scheduled for Oct 9 from 09:50-14:00 UTC and Oct 10 from  08:55-15:15 UTC. Listen on 145.800 during these times. The experiment is based out of Moscow, Russia so the times are optimized for the few orbits that cover that part of the world. 

Monday, July 22, 2019

Two SSTV events during July 29 - August 4.

Below is the scheduled (as of July 22) for the planned activation of SSTV from the ISS. The first session is the routine MAI-75 activity that is only active for a few orbits. It appears that the most of the world (except N. America) will get a shot during the two day run. Some lucky operators along the east coast of North America should get a pass on July 29.

Inter-MAI-75 activity
(July 29) GMT 210/13:15  – SSTV activate
(July 29) GMT 210/21:25  – SSTV power down

(July 30) GMT 211/13:50 – SSTV power up
(July 30) GMT 211/19:30 – SSTV shutdown

The second event will be a world wide event running from August 1 through August 4 and will be a memorial  event to honor Owen Garriott - W5LFL. He was the first person to operate amateur radio from space. We owe much to his efforts to bring the hobby to space for other operators. The schedule is below  (as of July 22)

ARISS Garriott memorial SSTV activity
(Aug 01) GMT 213/09:40  – SSTV activate
(Aug 02) GMT 214/14:00 – SSTV check
(Aug 04) GMT 216/18:15 – SSTV shutdown


** Update July 23, 2019**

The content of the upcoming SSTV transmissions may change. An update is expected after Friday, July 26 as to what the image content will be for the August 1-4 dates.

**Update July 29, 2019**
Reports indicate that some of the MAI-75 passes have audio that is normal and others have weak audio (signal strength is fine in both cases). Guessing that the hardware interface between the radio and computer may be having an intermittent issue as the computer was recently worked upon.

**Update July 30, 2019**
Confirmed that the SSTV images to be sent from Aug. 1-4 will be the Owen Garriott images. It is unknown how the current hardware issue will impact the operation during this period of time.

**Update July 31, 2019**
Below is the recent news release from ARISS. Of particular note is the mention of a certificate for successfully receiving and posting of one of the Garriott images.
