Hello Chris, LF,
Very interesting, your noise and DCF39 plot. One can clearly see that
the best time for a DL-YO contact is just before sunrise, where the SNR
of DCF39 is about 60 dB (!). Currently its just 15 dB!
I have an idea: Could you add another temporary trace where you show
the signal level of the level at 137.711 kHz +- 2 Hz? Then you/we would
get in impression of the SNR of my signal at your location. I would be
active regularly, even in the night. I think you would have to enable
displaying the maximum value and we have to think about the FFT width
and so. Would it be interesting for you? Maybe i can make some clear
peaks on that trace :-)

Hello LF,
Stefan's signal is weaker than usual today but nicely visible in QRSS3
in YO: http://qsl.net/4x1rf/yo/lfgrabber.htm
