LF: Re[2]: VLF: A weekend for newcomers and advanced newcomers...

Hello Stefan, Markus, Paul, VLF,
my results are not very good: only CIAO was decoded, other transmission not decoded :(
---------------------------------------------
found CIAO
list rank 7
reference phase  -30  -30  -30  -30
carrier RMS 2.670e-005 noise RMS 4.665e-006
carrier S/N 15.16 dB in 32.6 uHz
carrier Es/N0 -14.95 dB
carrier Eb/N0 1.58 dB
info bit period 1347.37 seconds
symbol error rate 411/1024 = 40.137 %
Es/N0 from symbol errors -15.0 dB
Eb/N0 from symbol errors 1.5 dB
Shannon capacity 5.5 bits/hour
Shannon efficiency 49.0 %
symbols file C:\EbNaut\ebnaut26_FEB_0221_8270-1pps-symbols.csv
elapsed 41 seconds

Also I "decode" carrier after 25feb transmission: http://rn3aus.narod.ru/DK7FC-carrier-26feb17-0435z.png 

And some ebnaut-files for reprocessing (if I probably have some mistakes in my settings for decoder):

I make little improvements (as I think) on my position - now only one rx connected to antenna system (not two)...
73!

Thanks Paul and Markus for the decode.

Everything seems to be fine! :-)
Soon Alex will be there with his results, i'm curious!

73, Stefan
