Related question: My K3 [S/N 642] which I built from the kit has
developed an "intermittent front panel problem," where tapping a switch
doesn't always yield the action it should. For example, tapping MODE UP
might yield the same result as tapping AGC. There is no guarantee that
the next MODE UP will result in AGC however, and in fact, it may
actually result in MODE UP or something else. I have found that if I
tap a switch strongly, requiring me to hold the K3 itself, it will
usually result in the proper action.
Some switches seem to be better than others, and those that I use the
most seem to be better than those I rarely use. I began to notice this
several years ago, occurring rarely. Frequency of occurrence has
increased slowly since then.
I know there is a mod to the FP connectors that involves gold pins, but
I don't know if that would correct this problem. The radio works just
fine otherwise. Maybe I'm just wearing out the switches?

Dwight,
That is not necessary when removing the front panel assembly.
It *is* necessary if you separate the DSP board from the Front Panel
board.
