Stefan,

A good signal here also - however I have been unable so far to produce a recording which will produce a successful decode. I will keep attempting.

Hi Stefan,

a booming signal here, as usual. Interestingly, simultaneous decoding of VO1NA is pretty much undisturbed, even though ebnaut-rx claims -14.1 dB carrier-based  Eb/N0 due to the increased power in the 115 Hz audio passband.

Unfortunately at this time I can't run autodecoders with the heavier code, the available PC took many minutes on full throttle just to crunch through the flat-phase trials. 

73 and good luck,
Markus
