Re: LF: EbNaut tonite

Stefan, Riccardo, Joe & EbNaut,

Interesting night!  

Excellent decodes from Joe all night at very low BER, of course.  Carrier shows +30 dB over noise

No successful decodes from Riccardo, though did get two Rank 0 decodes with random gibberish in the message.  The Eb/N0 levels were very low so the decodes were considered invalid.

No successful decodes from Stefan.  The 16K21A coding definitely maximizes computer resources here at 10.5 minutes per decode with an i7 processor!  

Cheers,

Rob - K3RWR

Stefan ... good copy throughout the night. Riccardo ... unfortunately only one decode to report. Markus noted a frequency error ... curious if propagation or NE0-M8T?
