Stefan, VLF.
I am afraid that there are no VLF tests in progress up here. It is a local
noise source but it is remarkably stable, it is coming from a DC-charger. I
will try to get rid of it as soon as possible.

Subject: VLF: Weak signal @ TF3HZ...
Hello Halldor, VLF,
I can see a trace on your "6000" 8970 Hz spectrogram, arround 8970.094 Hz
and 0 UTC. http://simnet.is/halldorgudmunds/TF3HZ_VLFgrabber/
Is it a local source or is there someone doing tests? No traces on the
grabbers here arround. But most of these, such as mine, do not display that
region, at least not in the 424 uHz spectrogram...
BTW the QRN comes down significantly for some time, very well visible at
OK2BVGs grabber. Promising! http://www.ok2bvg.cz/vlfgrabber/
