Thanks Chris,
And sorry, my VLF grabber list was incomplete. Now updated.
The traces are very clear on your grabber. Impressing. The last two step
frequencies are somehow blurred. A detailed reprocessing of this time
segment would be interesting but i do not take permanent recordings...
Maybe they shot the TX, hi.

Hi Stefan - two very strong staircases linking the three Alpha
frequencies also on my grabber http://g3wcd.bplaced.net. GBZ also went
off the air for a few hours this morning although it's back on now.
Quite a lot of activity at the moment around 82Hz.

VLF,
There was a "staircase" again from 12...15 kHz with a very strong
signal again!
Unfortunately the OK2BVG grabber just stopped a few hours before
that. There are not many active VLF grabbers these days.
The signal was visible at
