QSL cards and award for receiving SWSU satellites

CubeSat released from the ISS

CubeSat released from the ISS

On July 21 ten amateur radio CubeSats built by students at the Southwestern State University were deployed from the ISS. QSL cards and a diploma are available for receiving the SSTV, APRS and Voice messages

On his website Dmitry Pashkov R4UAB reports:

Small spacecraft (ICA), created on the YUZGU-55 platform, have been operating in real space flight for more than ten days. The cyclogram of work includes the transmission of voice messages, telemetry, call sign and SSTV images.

In view of the great interest in the space experiment “Radioskaf”, which is aimed at popularizing space research, Southwestern State University will be happy to send a QSL card to all radio amateurs who have successfully conducted a communication session with satellites.

To receive a QSL card, you need to send information: call sign, location, session date and time, carrier frequency, modulation type (APRS, FM-Voice, Robot36) and the result of a successful session (audio sample, telemetry text and image). The data is sent in the form of Applications for QSL. In the return letter you will receive the address where you need to send the card.

To obtain a diploma, you need to take 10 different SSTV images and voice messages, as well as decode 10 APRS telemetry messages (AFSK 1142 baud format) from any of the satellites, and apply for a Diploma

Satellite frequencies:

437.0000 MHz — SWSU-55 #8 — RS6S
437.0125 MHz — KETs#2 — RS12S
437.0250 MHz — KETs#1 — RS9S
437.0500 MHz — SWSU-55 #1 & R-390 #1 — RS10S
437.0750 MHz — SWSU-55 #2 — RS11S
437.0750 MHz — SWSU-55 #3 — RS1S
437.0870 MHz — SWSU-55 #4 — RS2S
437.0870 MHz — SWSU-55 #6 — RS4S
437.1000 MHz — SWSU-55 #5 — RS3S
437.1125 MHz — SWSU-55 #7 & R-390 #2 — RS5S

ISS SSTV June 8-9 145.800 MHz FM

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:
