Normally I dont need the DPB. But when in RUN-CQ mode with QRM in the last NAQP I was very happy to have it.

I also can hear that slight ringing on the mark and space frequency in the headphones with DPB. The ringing makes it a little hard to tell in the headphones if a really weak station is calling. I use the regular flat DSP filter now.
