ISS SSTV active on 145.800 MHz FM in April

The International Space Station (ISS) amateur radio Slow Scan
Television (SSTV) transmissions on 145.800 MHz FM are expected to be
activated over several days in April

The Inter-MAI-75 SSTV experiment should be active on:
• Monday, April 2 from 15:05-18:30 UT
• Tuesday, April 3 from 14:15-18:40 UT

SSTV is also expected be active from April 11-14 world wide as part of
Cosmonautics Day which takes place on April 12. Detailed times are
still being worked into the schedule and will be published later.
Images will be related to the Interkosmos project

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.
