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
