APF using RIT for precise centering.

The Audio Peaking Filter seems to work pretty well, however, the problem is centering it on the desired signal. Here is how I try to do that now: I use the RIT to try to center the peak, but the RIT is set too course (25 hz) for precise centering.

For APF  peak centering, we need the RIT (as tuned by the Flex Control Knob) to be at least 5 hz, and preferably down to 1 hz resolution. It would be beneficial if when APF is selected, that RIT also be selected, and set for 1 or 5 hz resolution, and when APF is deselected, RIT would also be deselected automatically. In other instances when APF is not engaged, RIT would function as it normally does now.

Of course as an alternative, a separate control could also be  made available for adjusting the peak frequency, as is done by the Elecraft K3. If this route is taken, the control should be by the Flex Control Knob, and not by a mouse controlled slider.
