Lilian decodes SSTV images from International Space Station

Many thanks to SWLing Post contributor, Lilian Putin?, who writes:

Greetings, my name is Lilian Putina and I am from Moldova. I’ve been following your blog for a long time, with the help of it I’ve purchased a short wave radio, SDR, and WRTH almanac.
I take everything a little bit: shortwave, FM DX, weather images from meteorological satellites, decoding of NAVTEX, WSPR and FT-8 etc.

I’m sending you two SSTV images received from ISS on June 30, 2018.

Many thanks, Lilian!  I’m also very pleased that you’re enjoying all aspects of radio–to me, that’s what makes this all so very fun!

Receive SSTV from space June 29-July 1

ARISS Russia is planning a special Slow Scan Television (SSTV) event  from the International Space Station Station around 09:00 GMT on Friday, June 29 and continuing until 18:30 GMT Sunday, July 1.

Supporting this event is a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using amateur radio, specifically the onboard Kenwood TM-D710E transceiver.

These images will commemorate the various satellites that were hand-deployed from the ISS. These will include the first satellite deployment from ISS: Suitsat-1/Radioskaf-1 which was developed by ARISS and deployed in February 2006.

The transmissions will be made on 145.800 MHz FM using the PD-120 SSTV mode.

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.

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

Listening to ARISS contacts last week

I get just as excited as my kids when I receive any communications from the International Space Station. This past week, we fit an ARISS contact fit into our hectic schedule during lunch break. I gave both of my kids a handheld radio and we all listened together as the ISS passed overhead.

Right on schedule, we heard NA1SS, but it sounded like they were struggling to make contact with KD2IFR at the Central Islip Union Free School District in Central Islip, NY.

I made a short video about one minute into the scheduled contact. I believe both parties were forced to move to their backup channel because we never heard an exchange–only NA1SS calling KD2IFR:

Still…we heard an astronaut live, so mission accomplished!

SWLing Post contributor, Mark Hirst, had much better luck last week monitoring an ARISS contact with King’s High School in Warwick, UK. Check out his excellent video:

Thanks for posting that video, Mark. By the way, I love your FT-817ND setup!

In fact, the King’s High School ARISS contact snagged some excellent publicity via the BBC.  Here’s an article via the Southgate ARC:

King’s High School ARISS contact on BBC TV

On April 19 student Eleanor Griffin led the live question and answer session between King’s High School (GB4KHS) and astronaut Ricky Arnold KE5DAU on the International Space Station (OR4ISS)

King’s High School strongly encourage their girls to develop their interests both inside and outside the classroom. This culture of empowerment led one of their girls to apply to ARISS Europe (Amateur Radio on the International Space Station) for a highly prestigious link-up to the International Space Station.

When Eleanor Griffin was selected to hold a space conversation with an astronaut, she was inspired to set up the Warwick Mars Project, for students across the Warwick Independent Schools Foundation, to further interest in Space Science. Eleanor says: “The moon landings belong to the generation of our grandparents, and the International Space Station to our parents. What will happen in our generation? Will Mankind travel to another planet?”

When asked what the incredible experience of the ISS contact had taught her Eleanor replied “Just do it! No one is going to stop you, if you just go and pursue your dreams, you really can do anything.”

If you missed these ARISS contacts, no worries! Check out the ARISS “Upcoming Contacts” page where future ARISS QSOs are listed. ARISS contacts are a great opportunity to show kids of all ages what you can hear with even a modest radio!

Listen to an upcoming ARISS contact with your scanner or HT

On April 18, consider setting your scanner or handheld VHF radio to 145.80 MHz around 15:57 UTC; you may be able to hear the downlink from the International Space Station. The Amateur Radio on the International Space Station (ARISS) contact will be between between NA1SS (on the ISS) and KD2IFR at a school in Central Islip, NY.

As long as you’re within the ISS’ signal footprint (which is rather large) you should be able to easily hear NA1SS’ side of the conversation. I’ve listened to the downlink in the past using an Icom ID-51a and the super compact Yaesu VX-3R:

The frequency of the downlink will be 145.80 MHz. As the ISS climbs above your horizon, because of doppler-shift, listen on 145.805, then move to 145.80 as the ISS approaches zenith and finally move to 145.795 MHz as the ISS drops toward the other horizon. As we’ve mentioned in past posts, you’ll know when to switch frequency when the audio gets bad.

ARISS contacts happen quite frequently–I’m posting this notice because I’ve noted it in my own calendar. Check out the ARISS “Upcoming Contacts” page where future ARISS QSOs are listed. This is a great opportunity to show kids of all ages what you can hear with a modest radio!

Check out a news article about this event via the Southgate ARC:

Upcoming ARISS contact with Central Islip Union Free School District, Central Islip, NY

An International Space Station school contact has been planned with participants at Central Islip Union Free School District, Central Islip, NY on 18 April.

The event is scheduled to begin at approximately 15:57 UTC. The duration of the contact is approximately 9 minutes and 30 seconds.

The contact will be direct between NA1SS and KD2IFR. The contact should be audible over the state of New York and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English.

Welcome to the Central Islip Union Free School District – Home of the Musketeers and a proud Suffolk County, New York school system, where approximately 8,000 students in grades Pre-Kindergarten through 12 receive their formal education. Our School District’s motto is Children Our Future ~ Diversity Our Strength.

About ARISS:

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and National Aeronautics and Space Administration (NASA).

The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.
