Jack,
? I have been having a similar issue, and found I got wider. smoother curves on 80 meters with my QMX+ if I configured the band edges closer to the actual legal band edged, then set the center frequency near the center of that, then used O to walk through each step of configuration. However, I don't know it the mathematical result is better because of that, because I didn't notice much real difference in the final SSB output, which is what this configuration is measuring. I lack proper test equipment for that and can only judge by ear. I think, at least in my case, I'm going to have to stop messing around and let people with the proper test equipment do the measurements and come up with conclusions.?
