Re: [Elecraft] KX3 CW Glitch with KXPD3/keyer?
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 avoid spurious contact, and it needs to be beaten much harder than what I'm used to. On the other hand comparing it to my Begali Sculpture is not fair. But I did write to Piero and ask if he'd make a paddle for the KX3, this was before the posts in this group, and he replied that he already was working on a prototype - I'm already signed up for it. But it would be nice if the Elecraft key could be modified to make it a little better with close contact spacing. Not sure if it's doable, but I'm open to any suggestions. So far, I'm planning to try rounding the contact screws like suggested by Wayne, and clean them up with DeOxit. Let's see how far that goes towards helping this issue. As I haven't been able to do more portable than back garden operations (weather only turned good this weekend!), so far I've mostly taken my Begali Sculpture out in the garden with me, but it won't be going with me on longer trips. 73, Thomas M0TRN On 24 July 2012 18:17, Ken Lopez wrote: > Steve, and All, > > I have similar problems with my KXPD3.

Re: [Elecraft] KX3 CW Glitch with KXPD3/keyer?
Steve, and All, I have similar problems with my KXPD3. This little paddle is cute and ingenious. But it drives me crazy! I've adjusted, changed springs, adjusted, fiddled, disassembled it, cleaned contacts. NOTHING seems to fix the generally clunky and inaccurate sending, random dits or dah strings, etc. The KXPD3 has less finesse than my 1962 Vibroplex Bug, and needs as much spacing and force to operate. I'm fed up with it. I'll be using my Palm paddles until Begali makes their Adventurer paddles available. Ken N6TZV PS: Love the KX3 though...

Re: [Elecraft] KX3 - CW glitch with KXPD3/keyer?
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 amongst some QSB. Then I told the guy I was running 1 watt HIHI. He was at 5 watts, QRO compared to me. I might get my first trail test of the rig this weekend. Im either going out for an 8-10 mile trip or closer to 15-16 miles, if all works out, Saturday/Sunday. Maybe the shorter route as I haven't hiked since last Fall, we'll see.

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.

I put a bit of a tweak to it, however. I noticed the set screws have a divot in them on the end that makes the contact. I took this back to flat across the whole set screw on a bench grinder (fine stone). Then I "rounded" them a bit on the same grinder/stone. After that I took my knife sharpening stones to the screws. I started at 120 grit and worked all the way through 6000 grit polish tape. The screws have a rounded near-mirror finish now. I don't have much key time with it just yet, but in the little I have used it just now it does quite noticeably improve the action. I spent a little more time tweaking the contact pressure/gap too. I had to play with it a little but I think its just about right. I will post back after a while and fill you in as to my experiences.

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 before I loaded that new firmware. After that first incident where it was very bad, I didn't have it come back at that strength. but I've seen a few missed/delayed dits and dahs with the KXPD3. So quite possibly it's this.

Re: [Elecraft] KX3 - CW glitch with KXPD3/keyer?/Cleaning contacts
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 lasts many months, in some cases more than a year. That problem did not exist before modern solid-state gear. Significant voltage/current flowing through the contacts provided a "self cleaning" action that broke down oxidation and other contaminants. Unless one carelessly used the key on a circuit that produced arcing, it was extremely rare for key contacts to require attention. But, with the miniscule voltages and currents sent through key contacts by modern gear, I found that keeping the contacts clean was a constant hassle until I stumbled across the DeOxit. (No, I don't own any stock in Caig...) 73, Ron AC7AC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] KX3 - CW glitch with KXPD3/keyer?
Steve, Ive had KXPD3 issues similar to those that you describe since I got my KX3 2 ½ months ago. Right out of the box I couldnt seem to adjust the paddles as tightly as I normally prefer. The adjustment screws have rather coarse threads and it seems like theres only about a quarter of a turn range between too tight and too loose, and when I first adjusted it the way I normally use paddles I would randomly get spontaneous contact which resulted in unwanted transmissions. I finally accepted the fact that Id have to settle for a more course adjustment and have now become accumstomed to that. At least that stopped the spontaneous dits. Ive also experienced random dropped dits, or sometimes a delayed response to trying to send a dit, which actually causes various sending errors depending upon the character Im trying to send. You know, with iambic keying if Im trying to interject a single dit between dahs and that dit fails, the result is a continuous string of dahs, etc., etc. I usually send at 25 -30 wpm. Ive never had a great fist, but some of my recent sending with the KXPD3 has been downright embarrassing. So Ive been doing a lot of apologizing and repeating during qsos. I discussed this with Wayne a few weeks ago and he suggested that I try cleaning the contacts. I took a close look under magnification and did find that there was a small ding on one of the brass contact cylinders right at the point where the screw tip makes contact (and it was the one on the dit side where all of my problems have occurred). I disassembled the KXPD3, and rotated the brass cylinder to get the dinged area away from the contact point. I also cleaned the contact areas with de-oxit as recommended by Wayne. The cleaning and adjustment seemed to solve the dropped dit problem (and I really think it was caused by the little "ding" rather than surface oxidation), but I continue to occasionally experience the delayed response thing. That is I hit the dit side of the paddle and there is a 1/3 or ½ second delay before it comes through. That, of course, breaks up my sending rhythm and results in more gibberish coming from my fist. I bought the KX3 for portable operation and certainly dont expect the KXPD3 to be anything like my Begali Magnetic Signature (which I believe would be an unreasonable expectation). As far as I'm concerned, the advantage of having the KXPD3 attached to the transceiver more than offsets the minor glitches I'm talking about, and I can live with them. But I would be a much happier camper if I could get to the bottom of this delayed response problem.

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 for over 50 years and never heard this one - or - somebody told me and I was out to lunch. Before discovering De-Oxit, I would periodically buy contact cleaner strips from various suppliers over the years. In fact just a couple years ago, Vibroplex even began to sell these strips. Now I can save some money to put toward another key ;) 73, Stan WB2LQF On Sun, Jul 22, 2012 at 2:43 PM, Steve KC8QVO wrote: > Yeah, I should have been a bit more descriptive.

Re: [Elecraft] KX3 - CW glitch with KXPD3/keyer?
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 of the counterpoise, but the feedpoint was set about 4" down in a bush (my "support" HI) so that affected it a little as well. Since the tuner was bypassed it wasn't trying to re-tune anything, but that doesn't mean the SWR was always "good" - I re-tuned the antenna a few times because of that. I will try cleaning the contacts and see where that gets me. I don't have any De-oxit but can get some in the next few days. I'll try the old paper abrasive method (someone once showed me that for cleaning my Vibroplex contacts - I use it for all my keys now).

Re: [Elecraft] KX3 - CW glitch with KXPD3/keyer?
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* an occasional
("random") delay (whether beginning with a dit or a dah) at the
beginning of a transmission. I was operating at those times through a
remote SGC autocoupler but had failed to "BYPASS" the internal KX3 ATU.
Wayne suggested that my ATU was "touching up" the match automatically;
trying to match my autocoupler. I went into the menu and bypassed the
ATU - problem solved.
There has been no reccurence of either of these issues since then.
