VLF: OK2BVG signal in Todmorden

[Markus Vester <markusvester@aol.com>]

Dear Lubos, LF,

 

beneath is a posting from Paul Nicholson in the Yahoo VLF groop. His spectrum from last Saturday morning shows three amateur signals, including yours.

 

Very good!

 

73, Markus

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.
