KXPD2 screws

[Elecraft mailing list]

Hello,
I’ve been offered a secondhand KXPD2 key for my KX3 but it’s missing the screws to attach it to the radio’s case. I’m loath to experiment with random fasteners so could someone please inform me what size the retaining screws are?
Thank you,
Al G4VSQ

I can't help you with the screw size, but I recommend contacting
Elecraft on this. The point on one of the screws is ground down to
eliminate some type of physical interference in the KX3. It would be
wise to use the screws that come with the paddle.

Al,

The screw size is 6-32 (not metric).
But do contact Elecraft to obtain the proper screws.  If the screws
project too far inside the KX3 enclosure, the PC board will be damaged.
I do know it can take a while to get items 'across the pond', but for
the health of your KX3, get the proper screws.

Hi Al,The screws are 4X40 1/2 " length. Elecraft # is E700245.. I highly recommend using these because of the printed circuit board behind the case and impossible to see. You might try the British Elecraft distributer.Oh, the KXPD3 uses the same screw..73,Jim HK7sss In a message dated 11/16/2020 1:39:46 PM Pacific Standard Time, [hidden email] writes:

Refer to the instruction sheet for the KXPD2:
 
 https://ftp.elecraft.com/KX2/Manuals%20Downloads/E740295%20KXPD2%20Paddle%20Instructions%20Rev%20C.pdf

This states that the thumb screws are 4-40 half-inch long.

I regret greatly my purchase of the KXPD2 in 2017.  It is the worst iambic key I've used in the past 40 years, with a bizarrely wide finger spacing that's twice that of the KXPD3 and all other iambic keys I've used.  It permits adjustment of contact spacing only and not the important spacing between paddles.  The paddle finger spacing is so wide as to be unusable.  Mine arrived missing one of the set screws (not shown or listed in the instruction sheet) designed to lock the contact spacing set screws.  The key came with a spare spring that is not described in the instructions (is it the same spring force as the installed spring?). The key requires two different Allen wrenches, but has a storage channel in the key frame for only one.  The design should have used only one size Allen wrench for ALL adjustments.

I suggest caveat emptor for the KXPD2 and the MH3, just as I did 20 years ago for the K1 KTS1 and KBT1.

Everything else Elecraft that I've owned since 2000 has been great, except for the radiant heat-absorbing paint job on the KX2.
