The solder is barely dry on the rig and people want to change the
freaking knob....Without ever having used it.
Just amazing.

What I was referring to is that with a flat the KX2 shaft is no longer
round, so the set screws can pull the knob off center unless they are
carefully positioned so they pull the knob against the round segment of the
shaft.
The shaft of the KX2 encoder is slightly smaller than the KX3 encoder -
about 10 mils - so that can contribute a small amount eccentricity as well.

Subject: Re: [Elecraft] new KX-2 question
Draw a circle on a piece of paper radius R, and mark it's centre. now draw a
smaller circle inside radius r, which touches the bigger circle at one
point, and mark it's centre. You'll see the distance between the centre
points is (R - r). imagine the big circle is the hole in the VFO knob, and
the little circle is the VFO shaft. The flat part of the VFO shaft is
irrelevant, as the screw is adjusted to meet it wherever it sits.
I hope this help explain how the knob will not be centred.

Leave one screw loose, drive the other one into the flat. How could it not
be centered?

It will fit, although the KX2 knob is a press-on type with a flat on the
encoder shaft while the K3 VFO B knob uses two set-screws on a round shaft.
Thanks to the flat, the K3 VFO B knob doesn't center perfectly.
