I’ve also decoded RS74S and additionally RS66S (Hyperview-1G).
Both are at 2k4 currently.
One of the 10 decoded frames:

RS66S-1 to R2ANF
… and already applied for QSL cards as PU4ELT informed us earlier.

There are more passes tonight so I plan to capture more data then so the time stamp is correct and not the time when I replayed the data.

If you have problems to decode RS44S (RUZAEVKA-390) or RS50S (Mordovia-IOT) using UZ7HO’s SoundModem for AFSK 1200bd, try Direwolf with the following line in the configuration file.
Modem 1143 1142:2285
It tells Direwolf to use 1143 Baud and the tones 1142 and 2285 Hertz (instead of 1200 Baud and tones 1200 and 2200 as of the standard Bell 202).
Try it on observation 10519815 at second 25. The other beacons in this observation are not totally clear enough to be decoded.
Direwolf outputs:

Hi Fredy.
I made an IQ recording (4 MHz width) this morning 08:30UTC (Orbit 11) and I did a quick replay as I had to leave the QTH. So I didnt process it deeply. Just some SSTV decodes. I will replay the saving IQ later trying to get more decodes and I will let you know in which freq the SSTV was.

Yes. Those 2 images were received in 437.050 at 08:27UTC, 6th-11-24. The first one was received just 1 second before of the flag of Zimbabwe, so I asumme that was not transmitted by Zimsat-2 but by one of the others sats SWSU-60 or Ruzaevka-390

Hi Vlad,
Thank you for this great hint.
You wrote that these settings are for … RS6S, ZIMSAT-2 and RS79S.
@geoscan put 1135 Baud into the transmitters for these three satellites.
Do you or Kirill have sources for this value or is it actually 1143 Baud?
Daniel
Hi Daniel,
So Dmitry R4UAB told me.

I have tried to receive signals from ArticSat-1 7 HyperView-1G but not been able to decode so will try again later, I may just have to set the ground station up to record passes as and see what I get as im not going to be near the computer and only on Ipad for some time.
This was from last nights Zimsat-2 pass over the UK.
