KX3 Knob Responsiveness

My old KX3 (S/N 763) is a great performer but I'm concerned about the "responsiveness" of the AF/RF Squelch encoder knob. The VFO (?) knobs (A and B) work great and the response to turns is immediate. If I turn the AF gain rapidly, the sound (and the numbers displayed as "AF xx") don't react in sync, especially if I turn it fast. If I turn the knob slowly, no problem.

Is this a known problem with "older" KX3's? Should I consider replacing the AF/RF Squelch encoder? The recent posting for replacing the "VFO" B encoder prompted me to ask the "learned masses"...

Re: KX3 Knob Responsiveness

Hi Bert,
I think this happens occasionally with the older encoders. Here is a
link to a page with the run-down on how to replace one, if you decide to
try it. Please feel free to contact me, as well, if you'd like to hear
some of the advice I got.

Bert,

I don't know that this is necessarily specific to 'older' KX3's. My KX3,
S/N: 6080 AF/RF-SQL and KEYER/MIC controls behave the same way if the knob
is rotated very quickly. It's always been that way. Not a big deal; I just
need to remember to turn the controls more slowly.

Re: KX3 Knob Responsiveness

Same with mine--about four years old. It is annoying, but I've adapted to
the quirk and now think of the behavior as a "feature".
