[Elecraft] [P-3] Feature request for easier QSY

[Ron D'Eau Claire]

I've had the same thing happen because I was being careful and pressing the
knob fairly slowly, trying to avoid turning it. 

What works is to set the knob for the desired value and then "stab" at the
knob to activate the switch. Yes, you'll often move it that way but the
switch activates within the 200 mS window so any change during the "stab"
isn't registered.

Hi Art,

off the desired frequency.

I'm surprised you're having that problem.  It did exist on early 
prototypes, but back around firmware version 00.23 I added an 
anti-false-knob-rotation algorithm for the QSY function.  It keeps track
of the last six MKR A or MKR B values during knob rotation and the time 
each one occurred.  When the knob is tapped, it assumes any knob 
rotation in the last 200 ms is not "real" and uses the last value 
before that.  So any knob rotation for 200 ms before the tap is ignored.

I do plan to add a MENU item to assign the knob tap to a FN key, but I'm
hoping nobody uses it!  If there's a problem with the operation of the
knob switch I want to fix it so people don't have to do that.

By the way, there were some improvements in the knob decoding algorithm
and MKR A and MKR B operation in versions 00.30 and 00.31, so you
probably want to be sure you have the latest firmware.  I think 00.32 is
the current release.
