Push one primary control button and the rest move inward!

[BOB PHILBROOK]

My kit K3 #818 has what appears to be a defect.  The defect may be by design or just in my radio.  When I push one of the 9 multi-function controls (the 9 buttons to the immediate left of the display) the 8 other buttons move inward too. Not a lot but one can see it happen.   I suspect this is a result of poor mechanical support somewhere behind the front panel.  Wonder how many others have noticed this?  I would think that flexing a PC board repeatedly is not good and will result in breakage down the road.  Your thoughts.

On K3 #202 I get no perceptible movement of the other 8 push buttons
when I tap or press/hold with normal force on any one of the other 9
buttons. You might want to take a look at your assembly process and make
sure that you have the correct spacers/washers. etc., in the proper places.

I have no movement here either (#705). I did the mod for the mic grounding which required removal of the front panel, the bottom and one side. I made sure proper spacers with proper type lockwashers were in the right places while I was at it. My unit is a marvel of machining technology - top cover, bottom cover and sides fit perfectly - even after removal and reassembly. I have never had that occur with my Icoms or Yaesu's - always had to fit force to get re-alignment on re-assembly.
