ARISS Russia is planning Slow Scan Television (SSTV) image transmissions on 145.800 MHz FM from the International Space Station.

UPDATE April 12: Transmissions on Thursday and Friday, April 11/12 had very low audio. Dmitry R4UAB reports the ISS cosmonauts plan to try to fix the issue on Saturday, April 13.

The transmissions begin Thursday, April 11, 2019 around 18:00 UTC and run continuously until approximately 18:00 UTC on Sunday, April 14, 2019.

This event uses a computer in the ISS Russian Segment, which stores images that are then transmitted to Earth using the ARISS amateur radio station located in the Service Module which employs the Kenwood TM D710E transceiver.

Once the event begins the transmissions will be broadcast at 145.800 MHz using the PD-120 SSTV mode.

Ham radio operators and other radio enthusiasts are invited to post the images they receive at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php

Moreover, on request, ARISS SSTV Award Manager Slawek SQ3OOK will provide an SSTV Award, details at https://ariss.pzk.org.pl/sstv/

To submit a request, please follow this procedure:

1. Load your decoded images at https://www.spaceflightsoftware.com/ARISS_SSTV/submit.php

2. Fill in the application form on the website https://ariss.pzk.org.pl/sstv/

Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and is subject to change at any time.

Dmitry R4UAB reports cosmonauts on the International Space Station will again be transmitting SSTV images, April 1-2, on 145.800 MHz FM as part of the Inter-MAI-75 experiment.

A Google translation reads:

“Inter-MAI-75” (Education and promotion of space research) – an experiment aimed at combining the efforts of educational universities and radio amateurs in Russia and the United States to develop technology and technical tools that enable students to communicate and collaborate with astronauts and astronauts in the study and development of the management process ISS, as well as to work out various methods of transmission and various types of transmitted information (text, voice and telemetry information, black and white and color photos and video from blasts, etc.), obtained as a result of scientific and educational experiments through the use of amateur radio communications onboard the ISS.

SSTV images will be transmitted at a frequency of 145.800 MHz using a Kenwood TM-D710 transceiver. They are expected to use the PD-120 SSTV format.

Schedule:
• Monday, April 1, 2019 from about 1400 to about 1900 GMT
• Tuesday, April 2, 2019 from about 1400 to about 1900 GMT

Tate Gallery features ISS and Amateur Radio as Art

The impressive artwork “Ten Minute Transmission”, featuring the amateur radio Kenwood TS-2000 transceiver and the International Space Station, is once again on display at the Tate Gallery in London.

The Tate Gallery says:

Ten Minute Transmission is a sculpture by Jennifer Allora and Guillermo Calzadilla modeled after the International Space Station. Made of wire and attached to a ham radio transmitter, this sculpture receives radio signals from the airwaves and transmits them into the gallery space.

This work was inspired by artist Alexander Calder’s suspended sculptures, or mobiles. Another influence was Russian artist and architect Vladimir Tatlin’s unrealised design, Monument to the Third International 1919, a tower with a rotating radio station at the top.

The title of this work, Ten Minute Transmission refers to the period of time when the International Space Station (ISS) can be contacted via radio as it flies past. The ISS orbits the Earth once every 90 minutes, but passes close enough to the antenna just twice a day. Usually the radio only picks up sounds of encrypted data packets sent back to Earth from the station. Two-way voice communication with the astronauts is now rare and needs to be requested in advance.

Collaborative artists Jennifer Allora (born 1974 Philadelphia, US) and Guillermo Calzadilla (born 1971 Havana, Cuba) are based in the United States and Puerto Rico. Their work examines the ‘space of encounter between people…whether it’s psychological territory or a physical terrain.’

ARISS is planning another of their popular Slow Scan Television (SSTV) experiment events. Transmissions on 145.800 MHz FM are scheduled to begin Friday, Feb. 15 at 08:45 UT and run through Sunday, Feb. 17 at 17:25 UT.

SSTV operations is a process by which images are sent from the International Space Station (ISS) via ham radio and received by ham operators, shortwave listeners and other radio enthusiasts on Earth, similar to pictures shared on cell phones using twitter or instagram.

When this event becomes active, SSTV images will be transmitted from the ISS at the frequency of 145.800 MHz using the SSTV mode of PD120 and can be received using ham radio equipment as simple as a 2 meter handheld radio or a common shortwave or scanner receiver the covers the 2 meter ham band. After connecting the audio output of the radio receiver to the audio input of a computer running free software such as MMSSTV, the SSTV images can be displayed.

Transmissions will consist of eight NASA On The Air (NOTA) images (see https://nasaontheair.wordpress.com/). In additional, four ARISS commemorative images will also be included.

Once received, Images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php . In addition, you can receive a special SSTV ARISS Award for posting your image. Once the event begins, see details at https://ariss.pzk.org.pl/sstv/ .

Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time. Please check for news and the most current information on the ARISS Twitter feed @ARISS_status or the AMSAT Bulletin Board

The SSTV images will be transmitted in PD-120 on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module.

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.

Snehal Vagadia VU3WHO (14), an 8th grade student of Saint Paul’s School, Rajkot, India, received the SSTV Image on February 10, 2019 at 5:33 AM UTC (11:03 AM IST).

It was good ISS pass with 56 deg elevation, strong signal were received using a 3 element Yagi antenna and a VHF HT tuned to 145.800 MHz. SSTV audio was recorded on a smartphone and later decoded with MMSSTV.

He got amateur radio licence at the age of 13 years and learnt ham activities from his father Rajesh Vagadia VU2EXP (Regional Coordinator, West India Zone, AMSAT-INDIA).

Help required in final tests before MarconISSta deinstalled

MarconISSta LogoThe International Space Station MarconISSta experiment will cease on February 9. Martin Buscher DJ1MBB asks radio amateurs with suitable equipment to participate in final tests.

The MarconISSta is a spectrum analyzer payload that monitors parts of the frequency spectrum in VHF, UHF, L and S band from the ISS in order to analyze current use and availability of bands for satellite communication.

Martin Buscher DJ1MBB writes:

We were just informed that it is likely that MarconISSta will be deinstalled on February 9, 2019. This is about three weeks earlier than expected, so we quickly have to finish any outstanding activities. Therefore: All Power To The ISS!

We want to invite everybody who owns a UHF antenna, preferably with an e.i.r.p. of more than 30 dBW, to do transmissions to the ISS. These transmissions will be recorded by MarconISSta and we will publish the results here. This experiment is a nice way for you to test your antennas, while it is great for us and ARISS to evaluate the ARISS VHF/UHF antenna pattern.

Transmission Details:
• Transmission time: Whenever you see the ISS between now and February 9th.
• Frequency: 435-438 MHz. Please avoid 435.95 MHz (our reference frequency) and 436.5 MHz (center frequency of receiver)
• Power: Continuous transmission of carrier, we recommend an e.i.r.p. of more than 30 dBW

Please do not use Doppler correction. We want to see the Doppler shift, it might help us to localize your transmission from this.
