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 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.
