Hi Wolf, VLF,

Today i can confirm that "that trace" is OE5ODL. He shifted his carrier=20
by 0.1 Hz for about 90 minutes arround 12 UTC. The signal is up to 20 dB=
=20
above noise in 381 km and was well visible the whole night through!=20
Compared to 8970 Hz, where the signal disappears in the noise in the=20
late afternoon this is an interesting difference. The trace is visible=20
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=20
callsign could be received without breaks...

Very good and promising work!

73, Stefan/DK7FC

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

  <pre wrap=3D"">I notice OE5ODL transmitting near 6470 today.

Very weak here.   Drifting a little, the signal is about 1mHz
wide which limits the resolution unfortunately.

Hi Lubos, <br>

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 :-)<br>
