I think everyone is missing the two essential points.

Nick - I used RWM on 9996.0kHz. I adjusted C22 so that I got the same
tone of beat note when switching between USB and LSB and offsetting the
frequency display by, say, 500Hz on each side of 9996.0kHz. Each time
you adjust C22 you need to go to the 7MHz band and do a CAL PLL.

Gil,
I've had a Hex for a year or so, and it's a good piece of hardware. I think
you'd find it to be quite satisfactory. I also have a couple of other
paddles, including a Schurr, and they're all good performers.
The Schurr has a dust cover which the Hex does not have (at least mine).

My HexKey is the best investment I have made. Once I got the adjustment

Never used a Hexkey here. Tried the Bencher paddles and disliked them very
much. I have two paddles I use with automatic keyers: Old Vibroplex
vibrokeyer which is nothing more than a shortened and reworked bug, and
the German Palm Key. The Palmkey is very small, but has a great feel to
it.
Woah!
-IF- you typed correctly and meant to say what you said, you're
approaching it backwards although you'd be OK until you needed
to send with someone else's correctly set-up paddles.
Benchers are wonderful paddles, IMHO, but the Bencher Hex Key
is even better. A fine key!

You are right on Ron, as I try to use a light touch. I think I would

of the magnetic, that has an immense (5lbs if memory serves) weight.

Sounds like you are missing one channel of the encoder -- first step
is to check the soldering. Looks like the two encoder channels ENC A
