Hi Paul,
Thanks! :-) That is correct!!! But why is the Eb/N0 so high, just the
low QRN in the morning? Impressing!
I'll continue with a longer message. Before i go to 5.17 kHz i would
like to pass a longer message through, like 20 chars or so.
But now let's try 6:
f = 6470.00000 Hz
Start time: 13.05.2016 00:00:02 UTC
Symbol length: 100 s
Characters: 6
CRC 16
Coding 8K19A
Duration: 15h, 33m, 20s
Antenna current: 200 mA
I'm watching the input signal of my feed back probe. It shows how the
antenna current varies with rain and temperature (affects the resonance
frequency). An inofficial capture is at
http://www.iup.uni-heidelberg.de/schaefer_vlf/VLF/TX.jpg . -37.5 dB
equals 186 mA.
73, Stefan

Copied 'UFB' Eb/N0 = +5.1 dB.
Carrier S/N: 11.21 dB in 24.0 uHz
