The Russian cosmonauts on the International Space Station are expected to activate amateur radio Slow Scan Television (SSTV) transmissions on 145.800 MHz FM during Monday and Tuesday, July 30-31.
The Inter-MAI-75 SSTV experiment should be active on:
• Monday, July 30 from 16:00-19:30 UT
• Tuesday, July 31 from 13:25-19:15 UT
The SSTV images will be transmitted on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module. It is expected they will use the PD-120 SSTV format.
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 http://websdr.r4uab.ru/
