Surprisingly good reception today. I got 55.42% decoded audio in this 63 minutes long log up until the end of the transmission.

At least they're trying... 11.72 kbps, still Mode C but the protection level was 0/0 today which might have helped. But why 64 QAM with this configuration?! Again no audio when the Doppler exceeds 1 Hz.

Almost 13% decoded audio today. If they would switch to 4/16 instead it probably would improve a lot.

I received this transmission at a signal level of about 40 dBuV, decoding started when the SNR was about 20 dBs. Some audio heard.
