Gary,
There was an issue with early KXPD2 paddles where one or the other
screws in the back of the assembly were slightly proud, and would
short that side out against the KX2 chassis if the thumbscrews were
completely tightened.
On my KX2, I now have a small chip of paint missing on the left side,
where that screw head had scraped the paint a bit, shorting out that
side of the paddle. It turns out that when turning the KX2 on, if it
senses a paddle line shorted, I think it ignores it, so depending on
your specific situation, you may find that one side or the other of
the paddle may not work, depending on which side was shorted when you
turned on the radio. If you leave the thumbscrews loose when turning
it on, you may find it works, then if you tighten the thumbscrew, you
will suddenly get repeating dots or dashes (depending on the shorted
side).
I 'fixed' mine by filing down the screw head, and putting a bit of
scotch tape over the paint chip. Unless you are looking closely, it's
not noticeable.
Elecraft did make alternate screws available for the KXPD2, but I
never bothered. It works fine for me, now.

Thanks Chris and Mike,
I initially tried a continuity check and had little luck confirming
bad or good continuity. I spent some time this morning putting it
in, taking it out, adjusting spacing, etc. Everything was pretty
inconsistent. For a while I had the left side of the paddle working
and the right not working, for a while everything was fine and now,
believe it or not the left paddle is working and the right paddle is
working as long as I don't completely tighten the left thumbscrew
that holds it on to the kx2 hihi! I'd guess it needs a cleaning.
I've misplaced the smaller allen wrench for the pivot screws so may
try to round one up and see if I can get it apart and cleaned and
back together. Or... maybe leave that left thumbscrew a little
loose :)!
Thanks for both of your comeback!

Hi Gary,
You can disconnect the paddle and do a continuity check with your
multimeter. It seems that the problem is on the paddle. You can
easily disassemble it to see where the problem is. I did clean
mine, and it is fairly easy.
Best 73,

the left side that doesn't work.
Is there a simple test I could do to determine if it is a paddle
problem or a KX2 problem? I don't have anyone local who owns a kx2
so I've no way to test with another radio.
