ARISS Russia is planning a special Slow Scan Television (SSTV) event April 11-14 from the International Space Station in celebration of Cosmonautics Day.
The transmissions are to begin on April 11 at 11:30 UTC and run through April 14 ending at 18:20 UTC.
Supporting this event is a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using amateur radio, specifically the onboard Kenwood TM-D710E transceiver.
Transmitted images will be from the Interkosmos project period of the Soviet space program https://en.wikipedia.org/wiki/Interkosmos
The transmissions which were coordinated with the ARISS scheduling team, will be made on 145.800 MHz FM using the PD-120 SSTV mode.
This is how this event was received on my shack:
