Re: LF: Re[2]: LF: Re[2]: LF: VLF NA Ebnaut - VO1NA on LF

[jcraig@mun.ca]

Hi Alex, Paul VLF,

Thank-you Paul for the summary.  It is looking a little more favourable
for a reception to the west.

One of the letters you decoded is correct, Alex.  I will try again
tonight, same message and parameters, unless the bad wx in the forecast 
brings down the aerial.

QRSS on 137777 rcvd agn in nr Moscow.

Also I try to decode ebnaut message from individuale files and from stacking 
procedure.
With little variation of time shift I have some characters from decoder:
"H"  - from stacking procedure 
","   - also from stacking
"8"
"+"
"S"
with rank < 20
and also "K" or "T"  with high rank

Unfortunately I do not know about true message.

Files for reprocessing are here:

reference phase -30 -30 -30 -30
carrier S/N 8.54 dB in 30.6 uHz, -36.60 dB in 1Hz, -70.58 dB in 2.5kHz
carrier Es/N0 -18.82 dB
carrier Eb/N0 0.98 dB
info bit period 5726.32 seconds

Es/N0 from symbol errors -18.3 dB
Eb/N0 from symbol errors 1.5 dB
