ISS SSTV activo nos 145.800 MHz FM em abril

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 https://en.wikipedia.org/wiki/Interkosmos

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.
