Thanks for the info Markus.

Yes, that long dash was Lubos.
OK2BVG was active that morning for a couple of hours.

I get this spectrum, (08:00-09:00, 278uHz bins)

http://abelian.org/vlf/tmp/110308b.gif

which has a small peak at 8970Hz - 3.0mHz, bearing east.

To bring this out I found the best S/N at bearing 110 and
I synthesised a unidirectional cardioid by combining H and E fields.

Only 3.6 sigma unfortunately.

Hopefully Lubos will do further tests. He should be visible
here with 30uW at 1423km if the tx frequency is stable enough.
