Hello Markus!
Sorry, my vlf grabber was "frozen", but after restart  a part of your signal was visible. 

73!

The transmitter has been on again 8270 Hz from 5:23, and I will have to switch off in a few minutes at midday 12 UT. As expected, noise during morning hours was generally lower than yesterday afternoon, with better traces observed by Paul Nicholson and Stefan DK7FC. I also successfully ran a spectrogram on the vlf6 webstream, which is received by Wolf DL4YHF in Bielefeld and rebroadcast by Paul: http://abelian.org/vlf/
 
Many thanks also to Roelof for the report, though a successful detection in 0.12 Hz bandwidth really sounds too good to believe - have you been watching 8270 Hz or kHz?

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.
