I personally like free-spinning knobs on both VFOs, and I especially
like the after-market weighted knobs that were available a few years
ago. I have them on both the K3 and KX3.
But dimpled knobs exhibit out-of-roundness since material has been
removed to form the dimple. When spun, such knobs will back-lash at the
end of their travel.
My ultra sophisticated procedure for perfect adjustment is to increase
the knob's resistance to spinning until there is no more back-lash as
indicated on the frequency display set to the smallest Hertz. The knob
is still free-spinning but when it stops the frequency stops.

I solved my KX3 drift problem, it wasn't electrical but rather
mechanical....reading in the manual about the VFO I increased the
resistance to the knob spin and *voila* no more drift! I really like
simple solutions to problems.
Thanks to all that offered advice, much appreciated.
