[Elecraft] Important KXPD3 keyer paddle installation note

[Wayne Burdick]

A few KXPD3 users have found that the paddles operated intermittently.  
This can be easily corrected.

First, completely remove one of the paddle thumbscrews. Next, using a  
drill bit that's somewhat larger than the #4 hole, add a *very* slight  
bevel (countersink) to the hole. This will remove a small amount of  
the black anodizing, allowing the thumbscrew to make consistent  
electrical contact with the keyer paddle housing. (The thumbscrew's  
post flares slightly where it joins the face; the flared area will  
contact the bevel in the aluminum.)

We've already added this step for KXPD3s shipped starting today.
