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

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:
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 which is currently in RDF mode on the loops is not being overloaded, other than showing some noise increase.
