ISS SSTV MAI-75 image 9/12 received by Chertsey Radio Club on Baofeng handheld
Russian cosmonauts on the International Space Station (ISS) are planning to transmit Slow Scan TV (SSTV) images on 145.800 MHz FM probably 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-D710E transceiver.
• April 7 start about 08:00 GMT, stop about 15:35 GMT*
• April 8 start about 08:40 GMT, stop about 16:10 GMT*
*Dates and times may be 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.

CAS-10 CubeSat has an Amateur Radio Transponder
CAS-10 CubeSat has an Amateur Radio Transponder
CAMSAT’s CAS-10 is an 8U CubeSat that will carry an Amateur Radio VHF to UHF linear transponder for SSB communications.
A follow on mission from CAS-9 and also known as Hope-4 (XW-4) CAS-10 is an 8U CubeSat, approx 228 x455x 100mm, with a mass of 12kg. The satellite will carry:
1. A VHF uplink and UHF downlink linear transponder with a bandwidth of 30kHz. This transponder will work all day during the life cycle of the satellite, and amateur radio enthusiasts around the globe can use it for two-way radio relay communications.
2. A camera, and the pictures it takes are stored in the flash memory on the satellite, we have designed a simple remote control system based on DTMF, and amateur radio enthusiasts around the globe can send DTMF commands to download the camera photos.
3. A CW beacon to send satellite telemetry data, which is also a feature that is widely welcomed by amateur radio enthusiasts.
4. A AX.25 4.8k/9.6kbps GMSK telemetry downlink
Planning a launch in November 2022 from Hainan Launch Center using a CZ-7 launch vehicle into a 400km circular 42.9 degree inclination orbit.
