ISS SSTV MAI-75 image 9/12 received by Chertsey Radio Club on Baofeng handheld
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.
