Hallo Paul,
Many thanks for the schönes Weihnachtsgeschenk Paul. I think it is a
Geschenk for both of us. We are a good team i find.
I guess that's the longest message (by amateurs) on VLF so far. When
starting on 46 km in summer, i didn't expect that we will manage such
good results there, so i'm quite satisfied.
There is still some confusion about unstable colours (-> phase) on my
local monitors, although things should works fine. There is no frequency
offset or drift, so the SpecLabs sample rate correction must work.
However the colours looks like a nice rainbow :-)
On the other side i can decode my EbNaut messages with 0 errors.
Strange. That was the reason why i stopped the DEC.24th transmission.
But maybe this has not been necessary. Anyway, now we are here :-)
It is now time for me to leave the 46 km band (again) and i will move to
the 58 km band. I will start a new thread... This thread has started on
May, 3th, 2016 :-)
73, Stefan
