There are interesting articles in the March Issue 93.
There was also a challenge last year initiated from AMSAT-UK. Vladimir, R9LR, called me a few times, he was also the winner.
RadFxSat-2 was launched Sunday, January 17, on Virgin Orbit LauncherOne launch vehicle. Reports from the launch provider stated that telemetry confirmed that the deploy commands had been sent and that all of the doors opened successfully, resulting in payload orbits that were all within the ICD limits.
Nominally, we expected to see “First (digital) Veronica” from the RadFxSat-2 telemetry beacon commencing 54 minutes after our deployment from the launch vehicle. That did not occur as expected.
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.

But I will give it a try if I can find a good transverter
This one?
No, It's my fault. Peter is right with the argument of sharing the passband. But for me after >30 years of OSCAR-operation it was and is always fun to hear me back.
With some of the details for the orbit, Cees Bassa has calculated a TLE
set for the ELaNa 20 cubesats (including FOX-1E).
Disclaimer: This TLE set may not be fully accurate but it is the best we
have until any satellite team or virgin orbit publish something better.

Right. Via satellites (OSCARs) we always works full duplex because to control our uplink. When you hear your own echo back, it's unusual at first, but then it's fun and you know that your uplink signal is OK. There are transverters to convert to a single band TRX, but then you can't operate in duplex, only in simplex and this has disadvantages compared to duplex via satellite.
I hope this helps.
