ISS sending images ... again!

Submitted by admin on Sat, 2018/06/30 - 11:54

Update:  SSTV signals were heard again July 5 at 10:10 am, so keep listening on 145.800.

If you’re staying inside out of the heat today, here’s something to do.  Tune your radio to 145.800, run a free little Slow Scan TV program on your computer, and wait for the images to fall from space!  The International Space Station is transmitting SSTV images periodically.   It’s as simple as holding your computer mic (or even your smart phone) up to the radio and wait for the ISS to pass over us.  See the links below for when the passes are coming up.

The picture above is a slow scan image sent from the ISS this morning (June 30), captured by holding a smart phone up to the radio speaker, while running  a free SSTV app on the phone.  No fancy interface or beam antenna needed, a simple 1/4 wave will do, and best if you have an outdoor antenna.  If you already have a special audio interface between your radio (or scanner) and computer, all the better.

From the ARRL Newsletter:

ARISS-Russia is planning SSTV transmissions from space. ARISS-Russia, RS0ISS, will transmit slow-scan television (SSTV) images from the International Space Station (ISS), starting at around 0900 UTC on June 29 until 1830 UTC on July 1. RS0ISS will send stored images commemorating various satellites that have been hand-deployed from the ISS. These will include the first such satellite deployment from the ISS in 2006, Suitsat-1/Radioskaf-1, which consisted of a discarded Russian Orlan spacesuit reconfigured to function as a free-floating Amateur Radio transmit-only satellite. SSTV transmissions will take place on 145.800 MHz FM using PD-120 SSTV mode (5 kHz deviation). The ISS Fan Club website will show when the space station is within range. More information is available on the AMSAT-UK website. -- Thanks to Southgate Amateur Radio News

The images are being sent in PD120 mode.  You can get more information on how to set up and where and when the ISS will pass by us by checking out the following pages:
