No correct results from the 25th and 26th either. I didn't try more stacking because adding in noisy days seemed to make things worse rather than better. The best decode was the one from the 23rd alone, EW antenna (log attached).

Best 73,

PS1: Under Win-10, Windows Explorer apparently crashes when trying to show details of a wav file with "zero" nominal samplerate.  
PS2: Your receiver on the tree seems to have gone off yesterday night.

Hi Stefan,

no decodes from yesterday Aug, 24, likely due to the much increased QRN already in the afternoon. I also tried to combine 23rd and 24th and still found the correct decode in the list, but with deteriorated SNR.

Well at least the decode has a 0.3 dB higher Eb/N0 and the ref phase is constant now. This is an improvement.
Again it was a very noisy day here. But soon that time will be gone! In a few weeks i don't expect local thunderstorms any more, which is very relevant on that 67 km band.

73, Stefan
