KXPD1 sensitivity

[Dan-204]

I just got done with my KX1 construction, including the KXPD1 paddles.
Another very nice setup from Elecraft! My question is how do I make the
paddles less sensitive to touch. I find that the left side (dits) is very
sensitive, and at one point, it started sending dits all on its own. I have
squeezed the wires inside down as close to the PC board as they can be, but
that didn't help. The right side of the paddle is working fine. Anyone have
any other suggestions??

Thanks, Dan W1RDB

Try swapping the rubber grips.  My craftsmanship left the wire on the "dit"
side is a little bumpy, even after squishing it with needle nose pliers-it
sends continuous dits with one of the rubber sleeves, but not the other.
Also, make sure the spring steel levers are aligned so that they fit into
the cavities molded into the rubber grips-if they are out of alignment even
a little, they will be trapped against the contact wire-I had this momentary
problem when I first assembled mine.  (Also, at the risk of telling you
something you don't need to know, check that your dit wire is not
accidentally grounding to the aluminum bracket somewhere.)

One possible problem is that one or both of the rubber covers is/are
installed incorrectly.  The raised portion of each cover must be on the
outside of each paddle.
