Hello Jacek,
Oh, indeed, very clear! I did not expect this at all. The loop, if it
behaves as a loop at all (!), points towards Paul. It should have a null
into your direction. Our distance is 976 km !

Why do you see the signal at all? I'm puzzled but it feels good :-)
Tomorrow, maybe i'll do something on 2970.01 Hz!

What is the antenna orientation?

Subject: LF: VLF Carrier on 8270.01 Hz from a ground loop antenna -
The 6th
station on Paul's spectrogram
Hi VLF friends,
Since 11:35 UTC i'm running about 2.5 A antenna current into my 900m
long ground loop antenna. Frequency is 8270.01 Hz. The signal is very
strong on my own grabber in 57.6 km distance but also at DF6NM, DL0AO
and it looks like there is a peak now on Paul's spectrogram building
up slowly.
I intend to run the carrier for 2 hours or so, until the accu is
almost empty :-)
The H bridge PA voltage is 175 V and the power consumption is 450 W.
Today, the DC measuremant result is 66V for 1 A antenna current. It
is cold and wet!
More soon.
