Have you tried all the K3's NB settings? I would be surprised if the K3's NB does not at least cut some of the interference down. I have seen some pretty brutal noise at my QTH on occasion and the NB always seems to at least chop some of it out to provide a readable signal. I have eliminated a S9 noise levels on 40M and be able to read a weak CW signal, where w/o the NB, you would not even know the signal was there.
