ISS Slow Scan Active

ISS MAI-75 Slow Scan experiment

ISS-MAI-75 29-10-2013 11:45UTCDmitry Pashkov UB4UAD reported that the Slow Scan Television (SSTV) experiment MAI-75 is active during October 28-29, 2013.

He also reports that on October 31, 2013 SSTV images will be transmitted from the ISS on 145.800 MHz showing photographic images of the life and work of the first cosmonaut Yuri Gagarin.

Today at the ISS pass from 12:45 UTC I received the following SSTV image from the International Space Station. The transmissions start late in the pass when ISS is flying over Russia. Therefor I could only receive one image with perfect quality.

Everything you want to now about ISS and amateur radio can be found at the website ISS Fanclub. They are also active on twitter so you don’t have to miss anything.

ISS SSTV reception

It is been a while for me, but today I had some pretty good SSTV reception from ISS on 145.800, the SSTV mode was martin1. For decoding SSTV data I use MMSSTV.

The transmissions started late in the pass and I think it has to do with the fact that our Italian astronaut is taking in consideration his radio friends in Italy. I was a little premature with this comment and IK1SLD gave the right information. He wrote to me via the AMSAT-BB mailing list the following.

Luca Parmitano doesn’t use the Kenwood TM-D710, this radio is used by Russian crew. The MAI-75 Experiment is a Russian experiment and the crew activates it when Moscow has AOS, so we lost 50% of the pass. Luca only use the Ericsson radio in the Columbus module.

Thank you Claudio (IK1SLD) for this update.

During the second day of the MAI-75 Experiment I could only receive and decode one image. It seems there where some problems with the radio because there was a carrier but no data being transmitted.
