The Slow Scan TV from the ISS on 145.800 MHz was planned to run from Saturday morning until Monday evening, but a space walk now scheduled for Saturday afternoon means the transmissions will be delayed
For safety reason the amateur radio transmitters are switched off during an Extravehicular Activity (EVA). It is not known what time the SSTV transmissions will now start. News of the space walk was posted at
Twelve different images depicting space pioneer Yuri Gagarin - the first human to orbit Earth - will be sent on 145.800 MHz using the SSTV mode PD180, with a 3-minute off time between transmissions.

The equipment used will be the Kenwood D710 transceiver located in the Russian Service Module. It is thought the equipment may be producing about 25 watts output which should provide a very strong signal. The D710 uses 5 kHz deviation FM. If your rig has selectable FM filters (most mobiles do) make sure you choose the wider setting designed for 20 or 25 kHz channel spacing, usually marked FM or FMW.

Plans are being discussed for transmitting new images from space enthusiasts around the world in the coming months. Additional details will be released.

In the UK newspaper the Daily Mail, Jonathan O’Callaghan wrote about how 22-year-old Radek Karwacki, an AMSAT-UK member, received pictures from the ISS using a £10 ($15) RTL-SDR dongle and a dipole antenna, see
