In your case, Martin, you appear to be receiving DCF39 well, but I expect it would work even better with a tuned antenna. My own system shows over 60dB between DCF39 and noise in an SSB bandwidth during the daytime, but of course I have less land between me (in Hertfordshire) and Germany. I have just looked at the database and cannot see your reports so I presume you are not uploading any.
