Hello Markus, VLF.
Sorry, but I'm QRT with my 8270 Hz
VLF grabber for a while... These day's I made a move into
Amateur Seismology.
In the northern part of the Netherlands, in the
provinces Groningen, Drenthe, Friesland and North-Holland, induced seismicity
occurs due to the exploration of natural gas. I live in Appingedam, where was
recently a 1.0 and 1.9 magnetude earthquake. Shaking area's are very small in
relation to earthquakes in Japan or Chili, but it creates a lot of damage to
homes and especially on the walls where cracks occur.
Of course I use my VLF and Hamradio experience,
so I'm using Spectrum Lab to view te signal from my
detectors and Argoupload to upload data :-)
In Dutch, but perhaps you can use Google Translate to
translate that page.
I tried, but I became a little sad about the translation
:-(

The carrier was on from 10:32 to 22:05 UT without interruption,
and was captured in Heidelberg and Todmorden. I've switched off for the night
now, and may do another shorter test tomorrow morning around 7 to 10
UT.

Since 10:32 I am on air again with a straight carrier on 8270.000
Hz, same power as in earlier tests (0.3 A current or about 10 to 15 uW ERP).
There seems to be a small peak on the DK7FC grabber, and I hope that some of the
currently dormant VLF grabbers (eg. OK2BVG, PA1SDB) may be coming online
again.
Interestingly my VLF grabber
http://www.df6nm.de/vlf/vlfgrabber.htm which is currently in RDF mode on the
loops is not being overloaded, other than showing some noise
increase.
Best 73,
