Thanks for report, Markus: well done with your autodecoder.

I'm testing a new NEO-M8T module:

TP1 as 1PPS connected to audio card (R channel), TP2 as 10 MHz reference source clocking the RTX DDS.

Tonite I'll try another EbNaut session. QSY on 137523 Hz.

Same parameters and scheduling.

Also got reliable and strong results on my autodecoder yesterday evening. Unfortunately some time after midnight UT, a spontaneous samplerate jump occured on my old grabber PC, so no more decodes during the rest of the morning.

Best 73,
