I have been twisting the KX3's PBT I/II knob madly in an attempt to change BW or CF rapidly, but in reality when I turn it more slowly the function actually changes more rapidly. Two possible explanations are either the encoder pulse rate exceeding the I/O refresh rate, or the speed with which the filter DSP can reconfigure.
I would love to be able to change CF and BW more rapidly, being spoiled by the instantaneous response of my old Drake R-4B's analog IF parametric filter. If the speed limitation with the KX3 is indeed a refresh issue, is there a way to increase the I/O refresh rate for the PBT encoder to allow for faster filter change via the knob? Of course, if it is a DSP horsepower issue, it is what it is. The overall performance of the KX3's receiver is so far superior to the R-4B, I don't want to use the R-4B much any more (well for that reason plus tube, old capacitors, size, power requirements and other issues, but that is another story).
