Hi Stefan, EbNaut

 

Attached is the file containing your last night transmission at 21 UTC

SR has the last sample rate, as corrected by the 1pps from GPS. The converter uses a 120KHz LO from GPS

So the soundcard center is at 17.540KHz for a zero frequency offset

Hello Luis,

Nice help charts, they should help the newcomers.

Well, i just checked if i can decode my own message from the local LF RX PC. Each message decodes as expected.
Can you show me your decoder settings and send me a .wav file? Is the sr.txt file updated?

73, Stefan

Hi EbNaut

 

Puzzling here trying to decode. Huge signal but no way to decode  L

Tried the 0.3s offset plus 4/Sample Rate but no way. Any other different offsets, even zero

 

BTW. This is my help chart to decode EbNaut https://www.dropbox.com/s/gdy7fqxtk8qukz3/EbNaut%20Decoder%20settings.bmp?dl=0

Complemented with, file export configuration in SpectrumLab https://www.dropbox.com/s/j9le8em2ac89sis/File%20Export%20configuration.bmp?dl=0

and SL file configuration for Markus EBnaut  tools https://www.dropbox.com/s/l4ty8yyi2yetaep/SR%20file%20configuration%20explained.bmp?dl=0

 

Decoding EbNaut is the hard side of the game

Hi Jay,

Pity. Did you consider the 0.3 second offset?

Surprisingly, I had no copy of your LF EbNaut signal last night.

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
