Hi Chris,
 
interesting that you see that line on 136320.0 Hz. It has been in my (old) Eu spectrogram all the years, reliable and precisely on frequency. I have often wondered what the source might be - the greenish colour on my DF and the fading pattern indicate Italian or Spanish origin.
 
There is also another unexplained southerly line on 137689.6, constantly visible at least in Germany and Austria.
 
Best 73,
Markus (DF6NM)

Hello Mal, Stefan, LF,

I don't think the 136.320 line you see on my grabber is your signal Mal, it's there all the time so it has to be a spurious and a very stable one :-)

My antenna is not yet optimized, I have made some tests with an active probe and will install it this week. Looks like there will be an improvement in SNR and hope to lower the sporadic high QRM level I'm experiencing in my location by placing it further away from the offending source (still to be identified, it could be from the outside mains wiring).

If signals are strong enough I will eventually make available a faster QRSS window.

73s
