[Elecraft] Loose buttons

Hi Dragan: If you press much harder than necessary to activate the switches,
the board on which the switches are mounted can flex slightly which makes
all the switches move. Pushing as hard as I'd care to in the upper right, I
can make the switches in that area move perhaps as much as 1 millimeter. 

The board is securely mounted to the front panel sheet metal, but by four
stand-offs - two just under the LCD display and two more just under the VFO
A and VFO B knobs - and by the nuts on the concentric pots on the left. All
of these attachment points are in the lower area of the board, so pressing
hard on buttons near the top will cause the board to flex slightly. There is
another board (DSP) mounted on the back side of the board holding all the
switches which stiffens the whole assembly, but it can still be made to flex
in some areas (such as the upper right corner) by pressing hard.

Hi all,

Since this summer I am a proud owner of K3-10/F and don't want to waste
bandwidth on my compliments to this great radio.

I guess that I have a problem with loose buttons in upper right corner of
the front board.
For example, if I press M>V button, other surrounding buttons are also
moving. Is this normal behavior?
If not, how to solve this?

I didn't find any post that describes this kind of problem. OTOH, on YouTube
I found a couple of blurry demonstration videos and I thought I saw that
those buttons are not moving.

Thanks,
