Stefan,
Just be sure that the TX antenna is not coupled to the E-probe. (
De-tune the system when you check it)
I'm mostly listening on my TX antenna, the E-probe is only a few meters
away. These two interact in such that the E-probe is just a bufferamp of
the main aerial.
To give you an idea how heavy this is: With a portable (AWP20 AKAI) I
can enjoy MF in the toilet and bathroom providing the radio is near the
waterworks and TX aerial is tuned.
IQ2MI is "good" beacon, just before sunset it manifest itself here and
build up to S-6 during midnight. During the winter you can enjoy it the
whole day.

FYI sometimes during clubevenings (Tuesdays?) it comes "live" with CQ.
But assume they will not listen on 477 :-(
Checked Meteox, during our QSO a heavy thunderstorm was over your QTH,
it moved away and lost a lot of it's activity.
Just to advise you that you shouldn't misinterpret your observations.

MF,
I took the QRSS/CW beacon signal from IQ2MI as the test signal. It was
very well audible here, R5. It was interesting to see the deep QSB.
Both, my small active antenna and the transmit antenna show the same
S/N but maybe it would be useful to use a antenna switch to compare
the S/N without having a time delay (changing the antenna cables), due
to the QSB...

Rik, MF,
Right now i'm testing the TX antenna as a RX antenna. This works much
better than expected. A 10 dB attenuator is needed but no problem.
Maybe you can give me a test signal again on 502 kHz, or someone else?
It looks like the QRN is much lower on that antenna. That means that
many of the crashes during my CQ calls have been charged rain drops
that were falling on the E field probe, just my guess.
I will listen another 20 min. on 502 kHz and apprechiate any test
signals from amateurs.
73, Stefan
