Mike, try these settings as a test and see what they do for you. In my own opinion, I have found the decode now is probably as good as it was before, just requires some different settings. I am listening to 5C13KD (Morocco) now on 20 CW and he is sending at 28 -30 wpm (per the K3 wpm checker) and I am getting very good accuracy with his signal going from S4 to S9 at my location.
