Hello Markus,
Thanks again.
The 3 char message from Nov 7-9 was QSO text, a Russian abbreviation.
You might know find the meaning.
You see, i'm struggling to pass that 3 char message over to RC4HAA :-(
Right now i'm trying to get a decode from 3 stacked days, but still
nothing. I'm getting loads of garberage messages, which appears to be
suspicious to me. There must be something wrong with their phase
stability, as i meant in the past already. I thought the average phase
will tend to be more stable so i should get a decode soon. But maybe i
am wrong. If i won't get a decode today i will repeat the message over
the weekend days again, then i will give up with RC4HAA. If i can
manage to get a decode, i will start to pass my call, i.e. 5 chars to
them. This will be the longest message for that path. Then i will turn
back to other bands...
73, Stefan

Here
are our results for the last three nights, showing good Eb/N0 and flat
phase. Unlike the somewhat mysterious three characters from Nov 7-9,
this time the message was obviously related to VLF work.
date DF6NM DL0AO (west)
Nov. dB dB
14-15 11.8 12.5
15-16 11.7 11.6
16-17 10.7 11.1
Note that DF6NM data happened to be slightly short, with 6.5 % of the
sequence cut off at the end.
VLF,
