[Elecraft] K3 Board Flex

[Ron D'Eau Claire]

Actually it has been both acknowledged Wayne and documented. Doug reported
it on the support reflector and several others immediately investigated,
including myself. 

Many, including myself, couldn't see the flex Doug found at first, looking
at the front panel almost straight on as when the K3 is being operated. 

When I got up close, looking at the buttons obliquely from the top like Don
did, I can see some movement when pressing the top row of buttons on the
panel. 

I measured the amount of flex. At the point of maximum flex, the board moves
about 1/32" of an inch (roughly 3 mm). The board is securely held in place,
but the nearest supports are points about 2.5 inches below and almost 3
inches to the side of the A/B button. 

That amount of movement wasn't enough to concern me at all. I'm not aware of
the button movement when operating the rig. I've seen boards in aircraft
systems that flexed at least that much with the vibration inherent in
flight, hour after hour, year after year, with no deleterious effects.

Still, Doug noticed it in his K3 and came up with a solution in true Ham
style that works for him. But, like many things, it's more like a matter of
personal preference than anything else. 

I certainly don't consider it a defect in the K3.

Hi All,

I moved the issue here:

http://www.zerobeat.net/mediawiki/index.php/Hardware_Issues_that_are_documen
ted%2C_not_yet_acknowledged_by_Elecraft

or 

http://tinyurl.com/285394

Just until we hear from the guys. 

My K3 has no flex at all, and considering equal
construction it's hard to imagine that some of the
boards are more flexible than others. ??? 

It's a bit too early to categorize this issue as
"accepted as normal" by Elecraft but documented for
comparison
with the K3 user base.
