That sounds like the switch on the encoder is going bad.  The encoder
switches and push buttons are all part of a matrix and "bad encoder
switches" is a known problem with earlier S/Ns.

All four of the encoders have been replaced in both of my early (~6xx
and ~14xx) K3s.

I’ll do a little more searching through the archives and then see what I can do.  I’ve discovered that if I push the rotary pushbutton CMP/PWR knob several times, the problems I was having with the other regular push buttons (e.g. band change not changing bands but trying to do something else) seems to have improved.
