Re: VLF: EbNaut transmission on 8270.1 Hz again - 73

[Markus Vester <markusvester@aol.com>]

Hi Stefan,

 

this time I finally got it (see screenshot). The QRN was not as loud as the night before (and the ground clip for the PC firmly connected ;-) For the long sequence, two 4.4 hour FFT-export files were joined together.

 

Paul, I noticed that in ebnaut-rx v0.4d the output with best rank seems to persist, rather than the one with fewest symbol errors (see join2-log.txt which is from the same wav, only slightly different start time). Is it meant to be that way?

 

Best "73",
Markus

I'm copying 'V3' with Eb/N0 = +2.0 dB.

Reference phase: -30 0 -30 0
Carrier S/N: 10.86 dB in 34.0 uHz

Lower noise last night, an average nighttime noise
level.
