I’m guessing 43768 - AISTECHSAT-2
but frequency maybe doesn’t match.

Thanks for you reply.
Version 0.09b of the SoundModem won’t decode Aistechsat-2 and apart from a different frequency, it additionally doesn’t send in 2k4.
So, it has to be another satellite.

200 kHz above its frequency and not 4k8 as mentioned, but in 2k4.

You are right, and the 5 times I’ve received and decoded it back in 2022 it was also 2k4. But it’s still mentioned as 4k8 on db.satnogs.org .
I’ll submit a new transmitter.
The last reception with data was 2024-07-20 in 2k4.
