Hi Eddie, LF,
I just thought that the LF signal of this night will become much weaker.
There was a layer of snow on the 2 hanging isolators which detuned the
antenna, i.e. lowered the resonance peak or the antenna Q. The antenna
current dropped to about 20% of the usual current. Probably most of it
passed through the snow. But after rising the input voltage of the PA to
maximum, it was possible to melt this layer of snow within about 4
minutes! :-) I saw the antenna current rising with some acceleration.
The automatic variometer permanently re-tuned to the new resonance peak,
indicated by the L+ LED :-) Then i saw some dropping rain drops on the
ceramic part of the isolator where the highest field strength is to be
expected. Fun!
Would have been interesting to see the rising field strength on DF6NM's
grabber :-)

That's nice, quite a potent looking signal on the waterfall there is
nothing like seeing it.

That is convincing. I go on in WSPR-15 on LF this night :-)

Hello Martin, LF,
Thank you for the report and the image. The image is most
interesting. I didn't expect that my signal is visible so well over
so many sequences. But there was only one decode at 5:30 UTC.
Here is a link to an image showing my results of last night,

the monitoring stations!
The LF DX season is not over yet!
