[Elecraft] KX3 speaker: distortion from mechanical vibration?

[Andrew Moore]

My KX3's speaker audio starts to distort as higher volumes at certain
frequencies. It's pretty clear that it's a mechanical vibration, and I can
dampen it by doing things such as applying pressure to the left lever of
the paddle, or gently pressing on the grille. I'm aware of the AGC
threshold adjustment, but that doesn't appear to be the problem.

I've tried adjusting the speaker mounting screws and blowing compressed air
gently into the speaker to make sure there's no debris in there.

Any other suggestions? Should be relatively easy to fix. Maybe a thin
rubber gasket between the speaker and the enclosure would do it.

I really like the internal speaker and would like to use it, as opposed to
an external one.

I love this rig!
