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 Slow Scan TV Event Feb 15-17

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.

You can receive the SSTV transmissions by using an Online Radio (WebSDR) and the MMSSTV software:
• Listen to the ISS when it is in range of London with the SUWS WebSDR http://farnham-sdr.com/
• Listen to the ISS when it is over Russia with the R4UAB WebSDR

If you receive a full or partial picture from the Space Station your Local Newspaper may like to know http://www.southgatearc.org/news/2016/july/now-is-a-great-time-to-get-ham-radio-publicity.htm

14-year-old Snehal Vagadia VU3WHO successfully received his first Slow Scan TV image from the International Space Station on Sunday, February 10.

VU3WHO ARISS SSTV Award

VU3WHO ARISS SSTV Award

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.

ARISS is planning another of their popular Slow Scan Television (SSTV) experiment events. International Space Station (ISS) transmissions are scheduled to begin Friday, Feb. 8 at 14:00 UTC and run through Sunday, Feb. 10 at 18:30 UTC on 145.800 MHz FM with the SSTV mode likely to be PD120.

Update Feb. 9: SSTV transmissions on Friday were at very low power, however, full power was restored on Saturday afternoon.

Among the radio amateurs receiving the pictures was Laura M6LHT who with Jenny will be using them to show students as part of the Music Man Project – Twitter @MusicManProject

The Inter-MAI amateur radio Slow Scan Television experiment in the Russian Service Module of the International Space Station is scheduled to be activated Jan 30 – Feb 1 on 145.800 MHz FM using SSTV mode PD120.

Update January 29: MAI-75 SSTV setup and activation starts Wednesday, January 30 around 13:30 GMT and ends around 18:30 GMT. Similar activation periods for January 31 and February 1.

The ARISS-SSTV Blog says:

Received information that the Moscow Aviation Institute will be conducting their SSTV experiment from January 30 – February 1.

It appears from the scheduling that the experiment will only be active during a couple of orbits that overfly Moscow instead of a continuous operation. Rough time periods of activation appear to fall between the hours of 13:00 – 19:00 UTC. Activity should occur on the traditional 145.800 MHz downlink.
