I'm far behind on e-mail, so apologies for being late on this comment. Also, I
notice that when I use a slashed zero in my call, a ? is substituted.
FWIW,
Yes, true in part as was the experience from the old analog data days, but the
'self-cleaning' action was usually due to a wiping action

Ken,
I'm a bit sorry to (mostly) agree with your points. The Elecraft folks are
certainly better rig designers than key makers. I'll say that the paddle is
usable up to maybe 25 WPM and above that it becomes too erratic. The
contact spacing needs to be far wider than what I'm comfortable with to
I discussed this with Wayne a few weeks ago and he suggested that I
try
cleaning the contacts.
Steve,
Another KXPD3 user recently pointed out something I hadn't considered.
Some other keyer manufacturers who use cup-point set screws as
contacts flatten (or round off) the screw ends
That's an old trick for cleaning open frame relay contacts use
some paper.. newspaper is fine, where there is no ink. The paper has
just enough abrasive quality to it to wipe off any oxide or dirt on
the contacts, but it's not so rough that it will remove the metal of
the contact
I use a chemical de-oxidizer/cleaner on my key contacts: Caig DeOxIT. It's
not cheap, but the tiny 25 ml squeeze bottle I bought years ago is still 80%
full.
I squeeze out a drop that hangs between the open contacts for a few minutes,
then I wipe the excess off with a bit of paper. One treatment
Wayne,
When you sent out the field test firmware I reported back to you an issue
that seems very similar to this - although at the time I was certain it was
a firmware issue. But looking at it now, it could well be this issue I was
having as well, and it was just random that it hadn't shown up

Never had the cited problem. I've reset the spacing to the way I like
it (twice) and no worries with contacts here. Twice just means I
was wrong the first time.
This may vary assembly to assembly.

I gave the KX3 an hour or so run on 40 meters and didn't have the original
issue I was having with the delayed dits. So far so good.
On a side note, I was running 1 watt. Lots of FUN! I didn't call CQ saying I
was QRP, I just threw my call out there. One signal report came back 579 in

Steve, I had a problem that sounded a lot like yours - At Elecraft's
suggestion, I sprayed my KXPD3 with De-oxit and the problem with
missing initial dits totally disappeared. I did not hae to
disassemble anything -- I just aimed and shot.
A few days later, I noticed that there was *still*
Thanks for the info, Stan. The antenna I was using all day yesterday was a
Buddistick on 17 meters. I bypassed the tuner and had the SWR down to about
1.2-1.4:1. There was some fluctuation in the SWR outside of that, so I
re-tuned the antenna a few times. The SWR changing was mostly from the lay
I don't know about that paper abrasive thing, Steve -- if it were me I
might check with Elecraft first. 73 ,Stan.

Guess I misunderstood -- I thought paper abrasive and abrasive paper
were interchangeable terms -- I imagined a fine abrasive of some sort
that might compromise the contacts' integrity and cause future keying
problems. Thanks, stan WB2LQF

Yeah, I should have been a bit more descriptive. The method I was taught is
to clamp a small piece of regular paper (notebook paper, printer paper, etc)
between the contacts and pull on it. If you clamp too tight on the paper it
will tear, but at just the right pressure you can pull the paper
I just tried it with computer paper and I captured some crud from my
Navy Flameproof. And there was no oily mess to clean up either. Maybe
you ought to send this one to QST Hints and Kinks. I've been a CW ham

I have been running all CW so far with my KX3 and have noticed there is a
delay a lot of times on dits. When calling CQ there is a hesitation when
sending my call between the dits in the V (KC8QVO) that makes it sound like
KC8QE UO or KC8QI AO. The first few times it happened I thought I just
