K3: concern about flexing FP board

[DOUGLAS ZWIEBEL]

I'm wondering if I left something out or what.....

When tap the VFO A/B button on the front panel, the entire top row of
buttons also moves ( keypad numbers 1, 2, 3, V>M, M>V).  You can see
it "pivoting" at the anchor point near the right-hand side.  Is this a
potential for a future failure?

I'd like to see an extra "brace" or two behind (or near) the VFO A/B
button to make the whole thing more stable.  All this flexing cannot
be a good thing.

Anyone else notice this?

Comments?

and no, I am not crunching the button...just tapping it moves everything.

I noticed this, too, until I continued with the assembly.  It seems
like there was a little rubber-like bumper on the PC board near the
M>V button which pressed up against the 2D fastener (as I recall) at
the top right of the radio when the front panel is fitted to the rest
of the radio.  This provided enough support for the board to keep the
buttons from moving on my radio.

Doug,

If your front panel is in the correct position with respect to the PCB
and the chassis, there should be an insignificant amount of
adjacent-key movement in the Z axis. I'll have Elecraft support contact
you to help with this.

Mine moves maybe a 0.001" if that - and I'm heavy handed.
The buttons 'stick out' about 1/8" and that's consistent across the  
entire FP.
