Hello Stefan, LF,

Trace added with Max Value for= 137.711Khz in 2Hz bandwidth. Will be interesting to see your signal on th= e plotter.

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 :-)

73, Stefan/DK7FC

Hello LF,

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