[Elecraft] Fix for my KX3 speaker distortion / buzzing

[Art Nienhouse]

/*I found the fix for my speaker buzzing which was the fit of the 
speaker grill fit between the upper half and the lower half of the case.
I filed the lower case for clearance on the sides of the speaker the 
vertical part on the lower case half both sides I now have 1/16 inch on 
the vertical sides and just a bit less on the lower side.
Before I reassembled the case halves I bent in just a bit the very 
bottom of the speaker grill across the bottom.
My speaker has the grill cloth installed the tone is not harsh but more 
mellow there is no detection of any buzzing while sending from an 
external key testing with out installing the
KXPD3 volume full (30) on the cw  monitor next I installed the KXPD3 key 
again no buzzing or distortion.
The issue for me is now fixed.
