I caught another Solar Flare in this log, a C 4.3 flare just around 12 UTC. I just came in and notiched that the SNR was rather low, so I stopped the log. After that I looked at
http://www.swpc.noaa.gov/rt_plots/xray_1m.html
and saw the reason why.

The days of high(est) SNR here at my QTH seem definitely to be over.

DRM car radio

Good reseption!
During the first minutes my FORD CD6000 car hifi system was on and gives reduced snr.
I can disconnect everything between perseus+notebook and the car audio setup, but as soon as any audio is audible from the car speakers I see a raised noise level on 41m. Seems as if the CD6000 is using some 7 MHz switchmode supply or modulation.

Reception was OK, but the variation in SNR is stunning.
