The International Space Station is transmitting SSTV pictures to radio amateurs around the world on 145.800 MHz FM

The Slow Scan Television image transmissions are expected to continue until 1800 GMT Sunday, July 23 and can be received on simple equipment such as a handheld radio or scanner with an outside antenna.

Some of the pictures already received can be seen at

CubeSat with Amateur Radio Transponder Set to Launch on February 15

Image result for cubesat image

For those interested in listening for and/or tracking CubeSats, this was posted by ARRL:

CubeSat with Amateur Radio Transponder Set to Launch on February 15

AMSAT-UK and AMSAT-NL have announced that at the Nayif-1 1U CubeSat, which includes a full FUNcube communication package, is set for launch on an Indian PSLV launch vehicle on February 15 at 0358 UTC.

PSLV Flight C-37, will carry more than 100 satellites into orbit.

Nayif-1 carries a U/V linear Amateur Radio transponder for SSB and CW and a telemetry transmitter. The initial plan called for a late-2015 launch.

Nayif-1 was a joint project of the Mohammed bin Rashid Space Centre (MBRSC) and American University of Sharjah (AUS). The United Arab Emirate’s first nanosatellite, Nayif-1 was developed by Emirati engineering students from AUS under the supervision of a team of engineers and specialists from MBRSC. The partnership between the two entities was aimed at providing hands-on satellite-manufacturing experience to engineering students.

Telemetry will be transmitted on 145.940 MHz, 1.2 KB BPSK (FUNcube standard). The SSB/CW transponder uplink passband is 435.045-435.015 MHz, and the downlink passband is 145.960-145.990 MHz.

AMSAT-UK is seeking post-launch reports from stations around the world, especially during the first few minutes and hours after launch. It is anticipated that the first signals may be heard in North America during the mid-evening hours on February 14 (local time).

A mission-specific telemetry dashboard is available. Information can be found on the web in PDF format at, https://funcubetest2.files.wordpress.com/2017/02/nayif-1_dashboard_notes_release_1-0b.pdf.

In a manner similar to that of the FUNcube-1 dashboard, this one will be capable of uploading the telemetry received to a central data warehouse. More information on the telemetry dashboard is available, as is a test file.

Initial spacecraft operation will be in a low-power “safe” mode, with just the telemetry transmitter activated.

I have had some fun tracking CubeSats in the past, and it is especially fun to watch your data appear on the dashboard history. And of course you are helping the research to boot!

ISS SSTV: Receiving images from space

(Source: Southgate ARC)

Slow-scan television (SSTV) transmissions are planned from the International Space Station (ISS) on February 13-14, 2017

The SSTV images will be transmitted as part of the MAI-75 Experiment on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module. It is thought they may use the PD-180 SSTV format.

The MAI-75 activities have been scheduled for the Russian crew on Monday, February 13 from 09:25-18:00 GMT and Tuesday, February 14 from 11:25-16:30 GMT.

Note the ISS transmissions on 145.800 MHz FM use the 5 kHz deviation standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try the wider filter.

The ISS Fan Club website will show you when the space station is in range http://www.issfanclub.com/

ARISS contact today: stream on the web or perhaps listen with your radio!

NASA Astronaut Peggy Whitson’s 7th Spacewalk (Image source: NASA)

Last night, my buddy Eric McFadden (WD8RIF) notified me that the International Space Station would be making a pass this morning and doing an ARISS contact with three schools in Belgium.

It appears this pass will create an opportunity for some of us at least in eastern North America (and elsewhere) to listen to the transmission live.

Eric notes:

The frequency of the downlink should be 145.800MHz. As the ISS climbs above your horizon, because of doppler-shift, listen on 145.805. Switch to 145.800 as the ISS approaches zenith. Switch to 145.795 as the ISS drops toward the other horizon. You’ll know when to switch frequency when the audio gets bad.

[…]The ISS runs real power so an HT with anything but the shortest rubber duck should be OK, particularly when the ISS is well above the horizon. A 1/2-wave whip on the HT is better.

The contact starts at 13:47 UTC (08:47 EST)–about one hour from time of this posting.

As Eric notes, pretty much any VHF handheld radio or scanner can easily receive this contact as long as you can tune to 145.80 MHz +/-.

Last time I was in a place to tune to the ISS, it was with my kids and we all got a kick out of hearing astronauts answer questions from children here on Terra Firma. I wrote a short post about this.

Don’t worry if you miss this ARISS contact–they happen all the time. Check the ARISS “Upcoming Contacts” (http://www.ariss.org/upcoming-contacts.html) page where future ARISS QSOs are listed. No doubt, it will pass over your part of the globe at some point!

Southgate ARC also posted the following announcement with a link to the live webcast:

ARISS contact webcast

On Thursday 12 January 2017, an ARISS contact is scheduled with three schools in Belgium.

Two schools will operate from the Euro Space Center.

The event will be web streamed live on:

The radio contact is scheduled at 13.47 UTC, which 14.37 CEWT.

The web streaming will start around 14.00 local time.

Thanks again, Eric, for the tip!

Upcoming Slow-Scan TV Images from the ISS

Almost flawless image received from ISS 2016-04-15 1859Z 64 degree pass

Above is a sample SSTV image received during a pass in April 2006 from KC4ALE on ISS Fan Club

An early Christmas gift for space enthusiasts around the world is coming again this year with Slow-Scan TV images from the International Space Station. Reception varies wide;y from location to location, but there are usually at least several passes which will yield good results.

Here is the announcement with pertinent details:

ARLS011 Slow-Scan Television Transmissions Scheduled from ISS

Slow-scan television (SSTV) transmissions from the International Space Station (ISS) are scheduled for December 8-9. The SSTV images will be transmitted from RS0ISS on 145.800 MHz FM as part of the Moscow Aviation Institute MAI-75 Experiment, using the Kenwood

TM-D710 transceiver in the ISS Service Module.

MAI-75 activities have been scheduled on December 8, 1235-1800 UTC, and December 9, 1240-1740 UTC. These times correspond to passes over Moscow, Russia. ISS transmissions on 145.800 MHz FM use 5-kHz deviation, and SSTV transmissions have used the PD120 and PD180 formats.

The ISS Fan Club website at http://www.issfanclub.com/ can show when the space station is within range of your station. On Windows PCs the free application MMSSTV can decode the signal. On Apple iOS devices, use the SSTV app available through iTunes.

There are a number of software program available for SSTV reception in addition to the ones mentioned above. It would be interesting to hear from folks who have used SSTV programs with their impressions. Good hunting!

ISS Slow Scan TV in April

ARISS reports that International Space Station (ISS) Slow Scan Television (SSTV) transmissions on 145.800 MHz FM may take place between April 11-15, 2016

The schedule for the ARISS commemorative event is currently:
• Setup and activation on April 11 about 18:25 UT.
• Paused April 12 from 12:15 until 14:15 UT to allow for a school contact with Romania.
• Paused April 13 from 12:45 until 14:30 UT to allow for a school contact with Argentina.
• Deactivation on April 14 at 11:35 UT.

This opportunity should cover most of the world during the operational period. The image transmissions should be on 145.800 MHz and the mode is planned to be PD180.

In addition, MAI-75 (SSTV Experiment) will be conducting two sessions afterwards. The first one is April 14 from 14:45 until 18:00 UT.
The second session is on April 15 from 14:10 until 19:00 UT. These times do not cross N. America but will provide opportunities for Europe, Southeast Asia, Australia and S. America.
