Im not that good to tell you which until Eu gets dark. Its not been very= good the past day or so with mediocre signals on 137 from DCF39 et al =A0= - still Ill be looking on any desired freq.

I can hear Loran clatter on 137 which means the local QRN is very low and= NDB "DD" (Located near Xlbreast, China) :-) is putting is a Ful= ly developed=A0signal.=A0

Nice clear night here already and looking for some=A0nice shooting stars..= saw a couple of

Anybody want to comment on whether their audio spectrum output=A0from thei= r SDR IQ is a bit "lumpy" with not exactly flat levelling across= the 1-4Khz range? Maybe my soundcard but I see some variations of a coupl= e of dBs on this one...
