LF,
Just found that the problem of my antenna is a self resonance caused by
the inductor(s) of the DC feed and the 30m long RG58 cable. When
connecting 1.5 nF in parallel to the coax, the noise is completely gone
and the signal seem to look better than ever!!!
So soon the system will work here :-)))
I am now monitoring in WSPR and OP8 and of course in
all LF grabber windows. From time to time there will be interruptions
but the culprit is found :-)
BTW thanks to Edgar/DL2HRE who was calling in CW on 472.2 kHz
about 30 minutes ago, calling QSX 501 kHz. That was a massive signal,
at least 30 dB above the noise, comfortable copy almost without a
noticable noise background, almost like the ID of a FM relais :-)

I discovered the world of receiving instead of transmitting ;-)
Due to the RX improvements i will receive in OP32 and WSPR
in the coming days, transmissions apprechiated!
Unfortunately something happened while moving the antenna 1m higher.
Maybe a bad contact or so. I have to investigate...
Tnx to the many active stations anyway. I'm now back on air as well.
Hopefully it works again later or tomorrow.
