Hi Wolf, VLF,
Today i can confirm that "that trace" is OE5ODL. He shifted his carrier
by 0.1 Hz for about 90 minutes arround 12 UTC. The signal is up to 20
dB above noise in 381 km and was well visible the whole night through!
Compared to 8970 Hz, where the signal disappears in the noise in the
late afternoon this is an interesting difference. The trace is visible
at http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html
A beacon transmission in QRSS/DFCW would be possible. Even the full
callsign could be received without breaks...
Very good and promising work!
73, Stefan/DK7FC

Hi all,
The 6470 Hz signal was also detected in Tordmorden, even though with
some difficulties.

I notice OE5ODL transmitting near 6470 today.
Very weak here. Drifting a little, the signal is about 1mHz
wide which limits the resolution unfortunately.

Signal is around 6470.0138 Hz, 0.1fT.

Hi Lubos,
A bit uncertain but it is worth to watch out tomorrow, maybe even a bit
slower... First 46km signals from Austria by amateurs at all :-)

Hello
Stefan and Ossi!
I am not sure, but it seems, I saw signal on 6470Hz. See the
picture, please.
