[Elecraft] [KX3] Speaker buzz fix with pictures

[Ron D'Eau Claire]

There's a way that does not involve any filing or grinding. 

I've found that the critical gap is the one at the bottom just below the
speaker where vibration by the speaker can make the edge of the metal move
back and forward, banging against the bottom cover.

That is easily cured by separating the top and bottom (you'll have to unplug
the flex cable and battery connector) and then, holding the top cover in
your hands with the inside facing you, press your thumbs against the edge of
the metal just below the speaker, bending it gently outwards. Repeat and
check the fit with the top cover until you have a comfortable gap and a
straight edge placed across the speaker lines up with the bottom cover on
both sides. On mine, the gap was about 20 mils when the section of the top
cover holding the speaker lined up with the bottom cover. 

The actual gap is not important. You'll know it's big enough when the buzz
stops. 

If you do that, be gentle with the flex cable, and avoid plugging and
unplugging it any more than is necessary. Those connectors are not designed
for lots of plugging in and unplugging and may become intermittent if
abused.
