Having followed the Sonate-2 thread, I listened for their APRS signal today on a 27 degrees EL pass. I received a good audio signal, recorded this, and then played it back into QTMM AFSK modem decoder. Oh! It wasn’t Sonate, but EOS-07 bird on the same frequency, also operating APRS!
Interestingly, during this pass, I could also see another bird sending weaker TM bursts on almost the same frequency, so I suspect that was the Sonate-2 signal.
