Russian cosmonauts on the International Space Station (ISS) are planning to transmit Slow Scan TV images on 145.800 MHz FM using the SSTV mode PD-120.
The transmissions are part of the Moscow Aviation Institute SSTV experiment (MAI-75) and will be made from the amateur radio station RS0ISS in the Russian ISS Service module (Zvezda) using a Kenwood TM-D710 transceiver.
December 1, 2021 (Wednesday) from 12:25 GMT until 18:45 GMT*
December 2, 2021 (Thursday) from 12:00 GMT until 18:05 GMT*
*Dates and times subject to change.
The signal should be receivable on a handheld with a 1/4 wave whip. If your rig has selectable FM filters try the wider filter for 25 kHz channel spacing.
