[Elecraft] Button malfunction on K3 panel

[Gary]

Chris,

This behavior can be caused by a lifting of the membrane.
If you remove the front metal face, look closely at the whole area around the mod button.
Mine had dirt get under a corner and gave me the same results your seeing.
Elecraft sent me a replacement membrane, I removed the effected section, cleaned it thoroughly and installed a new piece and all is well.
This was well over a year ago now and no further issues.

Hope this information helps

Gary

I also experience the band and mode button malfunctions all too
frequently.  My K3 is only about 8 months old, and because I live in the
lightning capital of the world, has had only light usage.

What I have experienced is that when the band or mode buttons are pushed,
sometimes it erroneously invokes other functions.  For example, pressing
band down, the VFO B display shows "NO ATU" and does not switch bands.
It's _not_ always the same error, it seems when it malfunctions, it is
random.
