LF,

Not yet a clear proof but probably i left a first trace in VK on 136.172=20
kHz in my evening transmission a few hours ago.

The VK1SV grabber ( http://people.physics.anu.edu.au/~dxt103/grabber/)=20
showed this spectrogram at about 20:10 UTC:=20
http://dl.dropbox.com/u/19882028/LF/is%20that%20a%207.jpg

It looks pretty equal to a 7 i find.

Note the time delay of the time stamp in the spectrogram and in the text=20
box in the left top corner. The correct time is that of the text box.=20
(We don't know where this delay may come from). The delay is exactly 30=20
minutes.
So that 7 must have been on air at about 19:15 UTC. This exactly matches=20
with my own grabber capture which can be seen at=20
http://dl.dropbox.com/u/19882028/LF/EU60.jpg

Also the frequency matches as well as the DFCW element length and the=20
DFCW shift of my DFCW-180 transmission. As a comparison i generated a 7=20
in a spectrogram with equal setting as used by Dimitris/VK1SV. Then i=20
cut that 7 and inserted it into the VK grabber capture, see:=20

Of course we will go on trying in the next time and hope to get a even=20
better proof. In that mode there is little room, i.e. time to receive a=20
complete call. The time is very limited. But maybe we will see a F=20
tomorrow :-)
I'm very optimistic you know.

That is a path of 16464 km :-)=20

PS: Will be quiet tonite due to VLF receive tests.
