KXPD2 - Iambic B

[MaverickNH]

Just starting to use my KPXD2 paddles on my KX2. I have them set to Iambic B.
The left paddle will give only dits if pressed and held any length of time.
The right paddle when pressed will give either dahs or fits and dahs,
depending on length of press. I can do a R or K by pressing the right paddle
alone.

My other dual paddles don't do that. Am I missing something? I've removed
and replaced a few times.

That paddle behavior is not correct.

I suspect that you have either a faulty paddle or it's just badly adjusted,
with the contacts too close.

I've had a paddle give strange results, where one paddle pulled on the
wiring when operated, which in turn pulled the wire on the opposite paddle
and made it operate too.

AFAIK there's nothing in software/firmware to allow that behavior to be set.

I initially had a similar problem - KXPD2 failing to key dahs properly/reliably. The main reason was the contact spacing was too close. I like a light touch and close spacing. I spent quite a bit of time adjusting the pivot pin play using the small allen wrench provided. You want them tight enough to not allow the paddle to "wobble" but not so tight that it binds. Once those adjustments are made, set the contact spacing where you like it but wide enough for the "swing" needed to make reliable contact. You can also use a small strip of stiff paper slid between the contacts to clear out any dust or corrosion.

The numbers I use for spacing and pressure for all of my keys, single
lever paddle, dual lever paddle and straight keys are as follows.

Contact spacing is adjusted with an automotive type or machinist type
feeler gauge to .005" or 0.13mm

The pressure to close the contact, measured at the tip of the level is
20 to 30 grams measure with a push type spring scale.

All of my keys are adjusted accordingly.   Thus changing from one to
another is not an issue.
