LF,

Just found that the problem of my antenna is a self resonance caused by=20
the inductor(s) of the DC feed and the 30m long RG58 cable. When=20
connecting 1.5 nF in parallel to the coax, the noise is completely gone=20
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=20
windows. From time to time there will be interruptions but the culprit=20
is found :-)

BTW thanks to *Edgar/DL2HRE* who was calling in CW on 472.2 kHz about 30=20
minutes ago, calling QSX 501 kHz. That was a massive signal, at least 30=20
dB above the noise, comfortable copy almost without a noticable noise=20
background, almost like the ID of a FM relais :-)

Unfortunately something happened while moving the antenna 1m higher.
Maybe a bad contact or so. I have to investigate...<br>
  <br>
Tnx to the many active stations anyway. I'm now back on air as well.<br>
Hopefully it works again later or tomorrow.<br>
