DCF39 is very dirty almost every night at about the times you have given. 74.321 area much cleaner and never see that junk there. It's hard to find nice clean spot in the 137 band compared to 74.32 region. Of course that can change am sure.
Markus even has worse artifacts at his QTH. I think your grabber is cleanest because you use direction RX ant that helps.
I will be on 74.321 tonight and see your grabber is running there-Thanks Hartmut-73-Bob

One of the most noticed characteristics of the 137 QRSS segment is that compared to the 74.322 segment, the 137.777 + and - frequencies are very "dirty" with multiple Loran artifacts, I presume are from Eastern Europe and Russia?
