Hello Markus!
I also thought about a coupling of antennas after playing around for a
while in SpectrumLab. I had to set up the DFCW30 Window because I
usually do not run one on my grabber.
The signal in the usual 6000 window was strong indeed but when I
switched to 30 or 60 or even 120, I wasn't able to see Lubos signal
clear enough to run a QSO.
I removed the antenna wire later from the coil but unfortunately it
didn't change anything. Still no usable signal in faster modes.
Lubos signal was good as many grabbers across Europe showed and this
made it very clear to me: I have got a problem in receiving. Due to
absence of signals, even this is hard to find out and was more than
worth the test.
At least the problem is identified and so I know what to focus on next.
