Until you appreciate that the K3 front panel buttons are all
totally corrupted then any cure to this problem cannot be found.
Sometimes the encoders on the four rotary/pushbutton knobs to the
left of the main VFO knob stick, and cause the problem of
nonresponsive buttons.
Try rotating/pushing these four knobs for a while. This was the
advice to me from one of the factory guys, and it worked. I went
ahead and ordered replacement encoders ($2 each), but I never
installed them because the rig has worked fine for a year or two
now after twiddling the controls, and installing the encoders
does not look like fun.
