[Elecraft] K3 Lost Control of Front Panel Buttons

[Christian Friess]

In my case it had to do with a bad encoder.

    /On the 4 small push-button encoders, tap each one and you will
    probably find one that does not toggle the LEDs. //
    //The old encoders leak resistance internally and it disrupts the
    push-button matrix causing wrong button pushes. //
    //Replace all 4, Elecraft part number E640018. //
    //You may be able to tap or snap the bad one repeatedly to get it
    back to working (but it will fail again). //
    //Keith WE6R
    /

With new encoders and additionally connectors update the K3 works fine now.
