Re: [Elecraft] KAT500 no PC comms
Two things I've noted with my KAT500 PC comms that you might want to quickly check: 1. More than once I've forgotten to stop the "KAT500 Remote" app before running the KAT500 Utility app. Since the Remote app is using the com port, it has to be stopped first. 2. That plug in the rear of the KAT500 can get partially unplugged with one more "click" needed to seat it fully and make it work. If that is the case, neither the Remote or Utility apps will be working. These have both caught me a few times, hope it is one of them since they are a quick fix. 73 de Chuck, WS1L chandler...@gmail.com On Mon, Mar 11, 2024 at 10:56 PM Mike Dodd wrote: > On 3/11/2024 10:40 PM, Mike / K5JR wrote: > > The KAT serial port is MONO, not STEREO, as I (not so quickly) > > discovered > > Good to know.

[Elecraft] KXPD2 Keyer
I just received my KXPD2 Keyer. First impressions are that it is very nice. I say that only because the KXPD1 that I got for my KX1 was a booger to adjust. My question is about the extra parts that arrived with the KXPD2, came with a loose spring and two Allen screws. Additionally the photos I have seen of the KXPD2 appear to show locking set screws that I assume lock in the adjustment screws, and on mine those holes are tapped for screws but no screws are there. The instructions mention that there is a compound on the adjustment screws the prevent the adjustment screws from walking out. Are the loose screws and spring spares? Or are they something that I can install? 73 K2CG Chuck G __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] [K3] KIO3 failure mode
A local ham friend had most electronics in his house destroyed by lightningnot a direct hit, but one where his ground returns provided a path. We have some of the worst lightning storms in the USA (Central Florida) and its a daily chase to make sure as much of our gear is not connected during the daily T-storms. There are some who are beginning to disconnect the RF and Electrical grounding of their gear due to the nature of lightning and its ability to find a route to true ground. Tough stuff, this lightning! I hope each of us does the best we can to minimize our exposure to the effects of a lightning discharge. Good luck to us all after we've done our best to disconnect from all sources of lightning intervention. Best 73 to all.

Somehow a transient from a nearby lightning strike (not a direct one to my tower) traveled through the laptop power brick and to an otherwise completely floating K3. If I remember correctly, the laptop power supply was even plugged into a quality surge protected UPS. It takes very little to zap the KIO3. I now disconnect EVERYTHING in the shack during lightning season. I was able to get a replacement set of KIO3 boards from Don, and even in that case the audio board I got from him was blown. Luckily my original audio board was OK and all I had to do was replace the RS-232 board. I don't know what I would do if the KIO3 goes south again since the primary use of my K3 is for contesting and I absolutely need connection to the logger for that.

Re: [Elecraft] Sherwood Receiver Tests
The K3 and K3S are dead ends --- they are frozen at their present capabilities. The K4 is a partially filled canvas that can improve over time. For example, the K4s I hear on the air still have, like the K3xs, that ugly popup in the unwanted sideband. They compare in this respect unfavorably with the lowly IC-7300. But the K4 will someday possess predistortion and consequently a pristine transmitted SSB signal. Unlike its predecessors, the K4 has an unlimited future. That's the nature of a full SDR.

Re: [Elecraft] KPA500 Issue
Hhhmmm... I'm coming late to this thread, as I wasn't paying attention before. Please forgive me if I have missed something but - I have, in the past, used both a K3S AND an old Yaesu FT-101ZD with my KPA/KAT 500 power combo. I *THINK* that is similar to what Jim is trying to do. Here is what I found, if it helps. When the K3S is on, it communicates with the KAT/KPA. However, when it is turned off, it leaves the KPA/KAT in a state where they are not prepared to accept input. I forget the specifics, because I have since provided the 101ZD with it's own amp. Try this - Turn off the K3S. Turn off the KPA. Turn the KPA back on, with the other radio connected to the RF input and at least an RCA keyline connected for the PTT. See if it works. IIRC, this was what I had to do. If anyone needs the specifics as to WHY it works that way, I can try to dig out the old emails with Elecraft. And, it's been a while so I may be mis-remembering the details. But, I know it worked.

[Elecraft] K2/100 in a high RF environment
Some background here - I volunteer aboard the museum ship USS Slater in Albany. She is a destroyer escort restored to her 1945 configuration as she was sent from the Atlantic to the Pacific after VE day. I try to put it on the air every time I'm there, once a week or so, maintenance issues allowing. We use a K2/100 and KAT100 patched through a WW2 vintage Transmitter Transfer Panel to a choice of the ships original wire antennas. These were mostly verticals used for receiving back in the day. We can also use the two original transmitting antennas, long wires running fore and aft. We are restoring a TBL 400 watt transmitter, which is only connected to the fore and aft long wires. The output exits the top of the TBL cabinet and consists of copper tubing that runs along the ceiling (I know, overhead... I'm a civilian) to where it exits Radio Central. Legend has it (and I have no reason to doubt it, I've seen the repair invoice) that the last time the TBL was fired up the KAT100 was damaged. Our practice is to unplug the feedlines to the KAT100 at the Antenna Transfer Panel, as well as where they connect to the rear of the KAT100 itself. The repair invoice says “The wattmeter in this KAT100 had been damaged. D1 and D2 were replaced. R1 was found to be open and replaced. C31 was not well soldered. “ Im wondering if unplugging both antenna feed lines from the KAT100 is enough protection from a 400 watt transmitter firing up a few feet away? 73 de Chuck, WS1L chandler...@gmail.com -- Sent from Gmail Mobile Chuck Chandler chandler...@gmail.com __ 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 Message delivered to arch...@mail-archive.com

My KPA-500 has been running great for several years. Recently I noticed it was making the occasional extra "click" or "thunk" upon powering up or down. Usually it would "click" when powered up and again when powered down, but recently a few seconds after the first click there would be another one, maybe more of a thunk sound. This afternoon I turned it on and when I pushed the Operate/Standby button I got a fault light and the 270V ERR message on the display. The menu HV option shows 68.4V, varying a bit, on my 240V line. I put it on the bench and opened up the top cover. There is a smell of overheated components, maybe burnt but more like too hot. I've submitted the contact form on the Elecraft support page. Any suggestions? For now, I'm running barefoot... 73 de Chuck, WS1L chandler...@gmail.com __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] KAT500/KPA500 with IC-7610?
I'm currently running the K3S with the KAT500/KPA500 combo. It works great. I'm starting to look at what my next rig might be, and have tentatively narrowed it down to the K4 and IC-7610. I know the K4 will integrate with the KAT/KPA just as well as the K3 does. How about the IC-7610? Are there significant drawbacks in the integration? How well does the iCom handle things like training the KAT for a new antenna via the rig TUNE button, or changing power levels between barefoot and QRO, for example? Are power settings per band supported? Any advice appreciated! 73 de Chuck, WS1L chandler...@gmail.com __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] The next generation KAT500
Actually there is a much simpler L-network search algorithm --- see my QEX article, "How to tune a L-network matchbox," Nov/Dec 2016. No iterations are required. You need only to sample reflected as well as forward minus reflected RF voltages on the line. Alas, QEX failed to print page 2 of the article so chaos reigned. Moreover, my approach only works without modification for high impedance loads. In general, knowing the forward and reflected RF voltages is enough to match without iteration. I will be delighted to email the complete article and erratum upon request.

Re: [Elecraft] What I need and meant
I use RUMlogNG on a Mac for my logging - I’m still looking for a good logging program for Linux - CQRLOG is not an option - requires too much overhead. RUMlog is a good general logger and has a contest mode that actually works pretty well. It was written and continues to be maintained and updated by dl2rum - originally for himself. It has become one of the best loggers that runs on a Mac. He now has a version specifically made to run on an iPhone or iPad. The iPad version will also (with the appropriate connection) talk natively to a K3 or KX3. I haven’t tried the iOS/iPadOS version since I don’t have an iPad or iPhone anymore (went android but that’s another story) but from what he has on his website, the iOS version looks pretty good. https://dl2rum.de/rumsoft/RUMlog2Go.html 73, Chuck - AA3CS On Wed, Jun 30, 2021, 14:59 Jim Brown wrote: On 6/30/2021 11:32 AM, Cameron wrote: > This is all being made all too complicated.

Re: [Elecraft] KPA500 TX with second radio SOLVED
I can confirm this approach works in practice, however one point is important - If you turn off the K3S, but leave the KPA on, the discharge time will be at least ten minutes. I didn't bother testing after that. If you turn off the K3S, then turn off the KPA, then turn the KPA back on, it has full functions - OPER, band change, etc. This takes only a little bit of time. I did not observe a KPA band change to 60M though.

Re: [Elecraft] KPA500 TX with second radio SOLVED
OK, I've figured out the problem. I took a step back and realized I am spoiled by the close integration of the K-Line. The reason the FT101 can't key the amp is because, unless the K3S is turned on, the amp won't leave STANDBY mode. Even with the AUX cable disconnected, the amp sits in STANDBY and pushing the OPER-STBY button doesn't do anything. I guessed a menu setting might control this, and setting the KPA Menu item RADIO to ANALOG now allows me to switch bands and from STANDBY to OPERATE via the KPA front panel buttons with the K3S turned off. A quick test shows 25 watts of tube-generated CW gives 450 watts output. Looks like I'm in business. Just need to change the menu item when I switch radios.

[Elecraft] KPA500 TX
Just a follow-up to my question about using the KPA500/KAT500 with a second, older radio. I just finished some more testing and found that when I remove the AUX cable from the back of the KPA and try to put the KPA into TX with the keyline, it stays in RX. A continuity tester confirms the rig keyline is closing when the rig is in TX, and the KPA shows driver power output, as does the KAT. But, the KPA won't switch to TX and amplify. Is there some other function keeping the KPA in RX even though the AUX cable is disconnected? 73 de Chuck, WS1L chandler...@gmail.com __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] Occasional second radio use with KPA500
I've been using the K3S, P3, KPA500 and KAT500 as my main radio. All three antennas are selected by the KAT500. I also have a second radio, an older Yaesu FT-101ZD. This rig can be switched into the lineup in place of the K3S. I sometimes enjoy using the older rig. In this manner the FT101ZD output goes through the KPA, then the KAT. I find the KAT plays well, a little tap of the key will cause it to auto-tune. I'd like to be able to use the KPA500 as an amplifier, but so far it won't key. I've tried the RCA Phono plug into the PA Key jack, but as long as the K3S is connected the KPA won't go into TX without the proper software signal. I did try with the software keyline interrupter a few months ago, but that prevented the K3S from switching the amp unless I also used a Y-connecter and phono cord from the K3S for amp keying. When I did the keying didn't seem as crisp, though. The K-Line is all connected as in the diagram on page 5 of the KAT500 manual. Ideally, I could turn off the K3S, switch the feedline from the K3S to the 101ZD, and have use of both the tuner and amp. Is there an easy way to do this? Perhaps one of those breakout boxes? Any hints appreciated! 73 de Chuck, WS1L chandler...@gmail.com __ 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 Message delivered to arch...@mail-archive.com

I have a K3s and a Q5 5 band V/U transverter. The Q5 has an input for band decode information. Has anyone attempted to use the K3S band data to control the Q5 transverter? The external transverter band data shown in my K3s manual is not consistent with the Q5 band decode data.

[Elecraft] Why predistortion?
*The Elecraft K-Line already produces some of the cleanest, puresttransmit signals around.* Au contraire! I'm in a morning roundtable where four use K3Ss --- all four have an unacceptable (only 32 dB down) popup on the opposite sideband on certain peaks. It has always puzzled me why Elecraft, so obsessed with received signal excellence, would settle for such flawed transmitted signals. My Orion Mk II with predistortion is far cleaner even driving two BLF188s. __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Mail for Windows 10
Most email clients send both an html and a plain text component. Some lists strip the HTML and only display the plain text. Others can accept HTML without a problem, for example Groups.io lists. Using Mail for Windows 10 with them works fine. >From my limited research it seems Mail for Windows 10 only sends an HTML component. The Elecraft list software then appears to accept the email and post the header, but not display any content. Whether or not it then generates an error message to the list owners I don't know. It certainly doesn't provide any 'bounce' notice to the sender. Caveat: I have no access to the list mechanisms, just a passing familiarity with having run a few listservs at work. Unless the list is capable of being re-configured (possibly with the ' *convert_html_to_plaintext* ' option?), I would urge some notice be given to users that this list is incompatible with Mail for Windows 10, since there does not appear to be any sort of error feedback other than that provided by other users who let you know your message did not get through. Doing so might also reduce the amount of "test" and empty-content messages on the list. Since Mail for Windows 10 is the default mail client for any PC running Windows 10, the issue is unlikely to go away on it's own. 73 de Chuck, WS1L On Wed, Apr 29, 2020 at 6:56 AM N4ZR wrote: > I, too, use Thunderbird with Windows 10.

[Elecraft] Mail for Windows 10
After reviewing several of my recent emails that came to the list as blank emails, and seeing a few of those every few days on this list from others, I am beginning to think the listserv here is configured to reject HTML Mail. The shack computer has Mail for Windows 10 on it, and that was used for a few emails recently. I also used my phone, and another computer where I was using the G-Mail web interface. But, the shack PC and it's Mail for Windows 10 seems to be the one that delivered empty or blank emails to the list. Can an administrator of the list (or someone knowledgeable about the reflector) advise if this list rejects HTML Mail? That appears to be the only format used by Mail for Windows 10. Alternatively, has anyone had success using Mail for Windows 10 for posting to this list? M4W10 settings don't show any send format controls, and a web search showed nothing but a series of complaints about the lack of plain text sending from 3 years back. -- 73 de Chuck, WS1L chandler...@gmail.com __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Poor CW note waveform resolved
Apparently one of my email clients is sending something the list won't accept. Here's my earlier email, hope it makes it! Well, I finally figured out why I was seeing a sausage-shaped waveform on the P3. I looked very carefully at the photo of a CW waveform shown in the P3 manual and tried to duplicate it exactly. I had been using the Spectrum and waterfall displays, so I disabled the waterfall display. The waveform looked better. Then I read the time scale at the bottom of the picture in the manual – mine was way off. Mine had been set at the default setting for Mod Scale of 25. In order to duplicate the picture in the manual I had to increase this to 100. That gave me the identical spacing of marks and value (10 mSec/mark) as in the picture. Once I did that, my displayed waveform looked identical to those in the manual. So, one problem solved… or perhaps resolved is a better word, as there is no indication the waveform was ever actually soft. Still a little more work to do on the CW sounding a little off at QRO QRQ. I’ll adjust the HV tap to bring full-load HV back up above 60V and see if that takes care of it. Many thanks for all the help and advice. 73 de Chuck, WS1L On Mon, Apr 27, 2020 at 9:08 AM Chuck Chandler wrote: > Well, I finally figured out why I was seeing a sausage-shaped waveform on > the P3.

[Elecraft] Poor CW note more testing and a question (rather long-ish...)
After several reports that my CW tone sounded less than perfect I've been on a hunt for possible causes. Looking at the TX waveform on my P3 it does look more sausage-shaped than I see in the P3 manual. So far I've determined my power supply was a little low and sagging a little under full power. After changing cabling and adjusting the PS, I now have 14.2V displayed on the K3 at rest, 13.9 to 14.0V at the 25W level used to drive the KPA500, and 13.7 to 13.8V at 100W output. All that now seems as it should be, but the waveform on the P3 is still elongated. My KPA500 on a 240V outlet shows HV of 73.5V at rest, 57.3V with 500W output. This is a little on the low side, and I may move the HV tap to bring it back up above 60V under load. On air testing today with a neighbor I got the report that my CW sounds just fine until the amp is in line. Then it is described as "some kind of artifact... like a bell sound... like a delay." This is consistent with the other report I had been getting of a "ringing, bell-like" note to my CW. This is most apparent at 30 wpm, as I would be running in a contest. So far, all the reports I have received from fellow amateurs have been after a CW Ops weekly contest, during which I usually am running at 30 wpm and 500W output. During rag chews with a bug at 22-25 wpm and 500W nobody has said anything bad about the CW note. The rig, KAT500 tuner and amp are interconnected via two E850463 Aux Interface Cables as shown on page 5 of the KAT500 Manual, Rev. C6 (3/8/2017). CW for contesting is generated by N1MM+ via the K3S USB interface. I have a K1EL Winkeyer on order in case the root cause is the computer... but that elongated waveform remains the most likely factor to resolve. My guess is the root cause of all this, power supply issues resolved for now, is the elongated waveform I see on the P3. My rise time seems to be at least 3 or 4 times longer than what I see in the ARRL product reviews or even in the P3 manual showing an example of a CW waveform. I have submitted a contact form at the Elecraft support web page, but its the weekend and with them all working from home I wouldn't mind the collective wisdom of the group as to any other avenues of investigation. And, many thanks for the help so far! 73 de Chuck, WS1L -- === Chuck Chandler chandler...@gmail.com === __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] Power supply update
I'm trying to keep the subject line updated... I'm now powering the K3S with just under 3 feet of #10, direct from the power supply to the rig, nothing else in the line. The K3S reads 14.2V at rest, 13.6V at full power out. The power supply at the terminals, using my DVM, reads 14.50 at rest, 14.44 full power out. The keying waveform looks better. I'll round up a local or two for some on-air tests later.

[Elecraft] Power supply V drop - was poor CW on K3S
Here's an update. I replaced the power cable running from the powerstrip with a 3-foot length with glass fuse holders in each leg. I also adjusted the power supply to 14.50V at rest. The K3S now shows 14.2V at rest. At 100W TX the K3S shows 13.2V, so a 1 volt drop. Way too much. The power supply voltage measured at the terminals drops from 14.50 to 14.44 for full power TX. This seems too much, I had read the drop should be no more than 0.01V and this is 0.06V. So, suspecting the in line fuse holders I made up another cable with dual blade-fuse holders, which was worse. TX voltage on the K3S display dropped to 12.9V. I'm suspecting my power supply is to blame - it's a TenTec 963, a re-branded Astron SS-30. Alternatively, I have another commercial power cable with fuse holders I can cut down and try. Many thanks for all the help both here on the reflector and the direct emails from several fellows, and to Rich VE3KI for the on-air tests this morning! 73 de Chuck, WS1L -- === Chuck Chandler chandler...@gmail.com === __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] K3S poor CW keying further investigation
After more checking, I suspect the internal 100W amp is the common factor in the poor keying characteristics I'm seeing and hearing about from my rig. I am trying to determine if my power supply is doing it's job. I'm using a TenTec 963 switching supply rated at 25A continuous. At rest the K3S panel display shows 13.6V, with full power key down it dips to 11.5 or so. This seems like a lot. I'm running the power cable thru a RigRunner Powerpole strip. If I can dig out another power supply from the packed boxes I can wire the K3S directly to the supply. Is 11.5V at key down enough to cause the slow rise time being reported? 73 de Chuck, WS1L -- === Chuck Chandler chandler...@gmail.com === __ 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 Message delivered to arch...@mail-archive.com

[Elecraft] Fwd: K3S poor CW reported with N1MM+
Here's some further info quoted from a fellow who has worked me a dozen times or so in the CWT's. We haven't had a rag chew so I'm hoping this is still a N1MM+ = computer = K3S issue. My last rag chew yesterday with a fellow when I asked, he described my bug-sent CW note as "very steady, pure" or words to that effect. "the keying is very very "soft" - the opposite of a "hard" clicky signal. The attack/decay time, i.e. the time it takes to go from full off to full on (or on to off) is so long that a string of dits at over 30 wpm almost melt into one another, making it hard to copy.

[Elecraft] K3S poor CW reported with N1MM+
Over the past few months I've been entering the hour-long CWT mini-contests each Wednesday. Four times post-contest I've gotten an email from stations I've worked calling my attention to a problem with my CW. It's not every time... I've entered 20 of these contests this year, and average about 80 QSO's each time. Also, outside of contest I always use a bug and always get good reports. The described symptoms vary... "sounds like maybe RF getting into it" and "Dits and dahs run together" and "your tone is not the same as others" "the weighting seems way off...didn't seem right in tone." Currently I have the K3S connected to the shack PC via the USB interface, with N1MM set for CW via DTR on the same port as rig control. The shack PC is an i7 quad-core 4.2 GHz with SSD and 16 GB of RAM. Lots of horsepower. I've added ferrites to both ends of the K3S-PC USB cable. I've monitored my CW (both bug-sent and N1MM+) via some WebSDR's, and it sounds ok to me. I've tried adjusting the K3S CW-Weighting menu item but monitoring that didn't seem to make any difference with the N1MM+ sent CW. For now, I've ordered a K1EL Winkeyer to try to take the PC/interface out of the CW generating chain based on reports that it prevents weighting and bad CW timing issues from occurring. I also ordered a USB cable with built-in ferrites to go with it. Hopefully that will solve the issue. Has anyone here had a similar problem? Any suggestions or hints?

Re: [Elecraft] KPA1500 Antenna Select Suggestion
I'd like to know more about this, as it would solve an issue I have. I have two stations, with multiple antennas switched between them with an Array Solutions Six-Pak. On 80 and 40 I have both a vertical and a dipole, and often one is better than the other. The tuning on them is different enough to cause a fault when switching unless I put the amp in standby, put the tuner in Auto, let it tune, then put the tuner in Manual and the amp in Operate. My amp is the KPA500, the Six-Pak is connected to Ant 1 on the amp. If there is a way to have the KPA500 see a high swr and pick from more than one known solution in less time than it takes to fault, then I could switch back and forth between two "similar but not identical" antennas to pick the best one as the signal fades in and out. I'd bet I'm not the only one who would benefit from this. If it's possible now, a quick pointer to the correct portion of the manual... if not, please consider it for an enhancement in the future! 73 de Chuck, WS1L On Fri, Jan 17, 2020 at 9:21 PM N4ZR wrote: > Gill, you don't mention which firmware you're running on the KPA-1500. > About a month ago the guys at Elecraft released revised firmware to help > me fix what sounds like an identical problem.

As a DXer who loves working pileups, I can tell you the best combination for me is A-Ab; meaning VFO A Audio (the DX station transmitting) is present in the left ear, and mixed in with the pileup (VFO-B) audio in the right ear. You can adjust that setting to taste (make sure you have the Sub-RX enabled first when you go into that menu item), but for me, A-Ab is the way to go.

[Elecraft] An ideal amplifier for the KX2
I've just finished building up a superb amplifier kit from Victor and Yana at eb104.ru that uses phase-change cooling. It will output 750 clean SSB watts with 4.5 watts of drive once I replaced the 10-dB attenuator pad with a 4-dB pi pad, namely a shunt 220, a series 24, and a shunt 220. The attenuator is easily accessible without any disassembly. (Arithmetic would suggest that the unmodified amp could be driven to near full coutput by the KX3.) It employs one BLF188 as the active device with well designed protection from excessive drive, SWR, or drain current. The amplifier is elegantly constructed, complete, and tested. You need only install it and its connectors into the included enclosure. As I should have expected from phase-change heat transfer, it runs cooler than any amplifier I have ever operated. See details at https://eb104.ru/internet-magazin/usiliteli-moschnosti/eb1200-heat-pipes-cooling-system I have built many amplifiers using eb104.ru modules. Their boards are of the highest quality in design and performance. You will have to supply 13.8 VDC, 50--53 VDC at maybe 35 amps, and an external bandswitch box with a wafer switch, since the amp is designed to be bandswitched by a transceiver via the DB25 on the rear panel. To play it safe I would use a PNP PTT circuit to protect the KX2's key out circuit from the current drawn by the (three) bandpass filter relays in the amp.

[Elecraft] K3 frequency offset problem
On a couple of occasions, I've noticed that my K3 display has been offset by approximately 0.90 Khz when operating CW. Both times, I found that when I tuned my K3 to a signal peak in the P3 display, there was no sound in the headphones. When I tuned 900 Hz past the peak I found the signal. This was a little embarrassing last night, because I issued a spot via DX Summit that was 900 Hz off from later spots on the same station put out by others. I found that the error could be corrected by turning the sub receiver on, putting the K3 in split mode, then going out of split and turning off the sub receiver. This problem may be associated with my habit of putting one VFO in CW mode, and the other in Data mode at one of the FT8 frequencies. The problem seems to come up when I turn off the WSJT-x program. My K3 has the latest firmware installed (5.66); I am using DXLab's Commander v. 13.8.1, and WSJT-x v. 2.0.0 . I'd appreciate any hints about what I may be doing wrong.

Re: [Elecraft] K3 -> Very Early Acom 2000A
In addition to a coax connection, the simplest approach is to hook up a key line from the Key Out on the K3 to the Key In on the Acom 2000A. Then, simply use a single "dit" (enable SSB+CW in the CW WGHT menu) to cause the amp to auto-tune on your current frequency. You can also issue a short vocal sound, and the amp will auto-tune. There are a few software packages that can listen to the K3 CAT frequency changes and send them to the amp, but I think they are more trouble than they are worth; it also requires a "special" serial cable. You should also set your K3 tune power to 15 watts which is what the 2000A expect if you wish to set a customize tuning solution for a particular band segment. That's all you need to be up and running. P.S.

Re: [Elecraft] Ham radio as a side dish
Not me, a friend of mine... Who is a pilot. Not just a pilot, but certified by the FAA to give check rides for small airplanes. I don't know the specifics, but he does aerobatics and all that. Anyways, he's a contester and DX'er as well. But, even though I'm sure he's a really good pilot, even he had to have a check ride. He was up near New York City, having a check ride and apparently there is a flight area along the Hudson River that is really, really tricky. Has to be flown just about perfect, so that was his check ride area. His instructor, who apparently was at an even higher level, told him to request the clearance for that corridor and ATC gave it to him immediately. His instructor wasn't expecting that and told him words to the effect of "Be careful. You talk better than you fly." Apparently ATC tends to be hesitant to clear private pilots into that corridor, but years of DX and Contest operations gave him the, shall we say, savoir faire to be cleared without hesitation. His request was apparently crisp, clear, unequivocal and brief. For my part, having been a cop since 1980 I've usually been the guy folks go to for technical stuff. Beyond radios, even. Somehow I am expected to know about cameras, computers, networking... and I've even picked up quite a bit of it on the way. 73 de Chuck, WS1L On Sat, May 26, 2018 at 11:27 AM, Martin Sole <hs0...@gmail.com> wrote: > I can really relate to these two. > > As a kid I played drums.

Re: [Elecraft] Longer K-Pod cable?
Bob: I made one to allow it to reach around the back of the desk and then underneath to the keyboard tray, so the K-Pod is right next to my computer mouse--very handy. Make sure you get the wiring correct, as W3PFR points out, pin 1 must not be connected, else you may get some "interesting" results. I ordered a 6P6C cable, cut off one end, then crimped on my own connector with the pin 1 wire cut back and therefore disconnected. If you do this, be sure to mark the cable ends, as noted in the K-Pod manual: *"If you disconnect the wire at only one end, be sure that end is plugged into your K3S or K3."* (p. 19) --- Chuck Milam, N9KY n...@arrl.net On Thu, Apr 19, 2018 at 8:16 AM, Bob Novas <bob.no...@verizon.net> wrote: > Can I just makeup a 4 wire cable that is longer than the cable supplied > with > the K-Pod?

Re: [Elecraft] K3 macro to tune memories from K-pod
I did check my firmware revision numbers, and have 5.62 and 1.09 in the K-pod. In my original post I stated that after sending the M>V macro (which does bring up the flashing memory number) that pressing the Up or DN macro caused the display to revert to its original frequency and nothing else happens.. That's not quite right. Subsequent sends of the UP or Dn macros cause VFO A to increment or decrement. But sending either the Up or Dn from the K-pod kicks the K3 out of memory mode. Everything works perfectly from the utility, so it seems to be a K-pod issue.

[Elecraft] K3 macro to tune memories from K-pod
I am trying to set up the K-pod to step through the K3 memories like using the M>V button and main dial. To do so I've programmed 3 of the K3 pf buttons with one command each: Macro 14 (labelled M>V) = SWT23;Macro 15 (labelled MEM UP) = UP;Macro 16 (labelled MEM DN) = DN; I realize that the UP and DN command are for menu items and frequency changes, but thought I would try them for this. From the K3 Utility this works perfectly, replicating the radio front panel action exactly. However, from the K-pod it doesn't work. The M>V macro works, but MEM UP and MEM DN simply revert to the existing frequency. A second tap flashes the correct label on the K3 but nothing happens. Can anyone shed light on why this works from the utility but not the K-pod? And while I have the floor; I will re-utter my plaintive cry for a macro editor for the P3/SVGA. I have no idea what is entailed in creating one, but it would make it so very much easier to work with them. 73, Chuck, NN7U __ 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 Message delivered to arch...@mail-archive.com

[Elecraft] Static Discharge Through K-Pod
Greetings, All! I'm getting static electricity shocks through my K-Pod case, and I need some suggestions for mitigation. Background: I keep my K-Pod on my operating desk just to the right of the shack computer mouse. I've noticed when I walk over to the desk and grab the mouse, the K-Pod will beep. Further investigation shows I'm getting static electricity discharge from my finger through the K-Pod, this morning I even noticed an arc from my pinky finger to the K-Pod case. When the K-Pod beeps, the D1 and D2 lights will cycle. The shack is carpeted, and I have a rolling chair on one of those plastic chair mats (which can probably go away if necessary,) I suspect that mat is probably contributing to the static problem. Obviously, I don't want static electricity discharging through my K-Pod and then through my K3. I'd welcome any ideas for static mitigation strategies. I was thinking some sort of grounded mouse/keyboard mat, which used to be more common, but seem hard to find these days. 73, Chuck Milam, N9KY n...@arrl.net __ 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 Message delivered to arch...@mail-archive.com

[Elecraft] Planning the next filters
Right now I have the stock SSB and a 400 Hz filter in both main and sub rcvrs. I would like to add some a few at a time. My first priority is to add a couple to the main receiver, since it is the biggest chore to get to. I plan on a 250 Hz CW filter, but am going back and forth between the 2.1 and 1.8 kHz filters. I know that narrowing the DSP to 1.8 gives a really difficult to understand voice signal, while the 2.1 allows in more adjacent signals. However, the roofing filters may not behave in the same manner. For example, the 1.8 could be set to turn on at 2.1 to take advantage of skirt shape. I primarily DX, and operate in some contests as well. I know SSB contests really need a narrow SSB filter. Any suggestions on the matter from those who have gone this route before? 73 de Chuck, WS1L -- === Chuck Chandler chandler...@gmail.com === __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] KX3 Utility Segmentation Fault in Linux
Whoa, a Linux question? Excellent. Looks the HarfBuzz shared libraries got updated (probably along with your window manager of choice) and the kx3util needs to be rebuilt (relinked? Not certain of the proper dev-speak here) to reference the newer libraries. (Sorry if I'm preaching to the choir.) See if you can get the core file to drop (you may need to do a "ulimit -c unlimited" to ensure you get one) and analyze it with gdb for more information. I wonder if you can do a workaround and keep the libharfbuzz library files that kx3util is looking for installed (maybe in /usr/local or somewhere else handy?) I'd test this myself, but I confess I gave up tilting at the windmills years ago and use Win 10 for ham radio applications. I do keep my Linux boxes around for network and vulnerability management.

Nice to get quick responses from people who know the product! The amp was used for the entire contest weekend without a hint of trouble. I tried to watch the power out and keep it out of the red. Even when I was on a small run the temp never got above 52 C. The tuner worked great as well, only a couple of times it refused to find a match when I was using low band antennas well outside their sweet spots. Nothing a button push wouldn't cure.

[Elecraft] Antenna switching question
Currently I have five antennas connected to my K3S via a manual switch: LPDA, 20 through 10 Vertical, CW on 80, low end of 40, 30, 20, 17, 15, 12 and 10. Dipole, Phone on 75, phone on 40, 20, 15 Inverted-L on 160 Yagi on 6 Mostly the antennas are below 2:1, but they need some flattening on 160, 80 and 40 if I have to go beyond their sweet spots. When I build the KAT500, what is the best use of the 3 ports available to maximize it's tuning algorithm? In other words, how can I maximize the likelihood that a band change or QSY will result in a rapid tune due to prior memorization, versus a somewhat longer full tune? My thoughts were perhaps to put the 6 and 160 antennas each on their own KAT500 port, then use the manual switch for the three that would cover HF. Fine, except there could be a situation where the KAT500 had memorized a tune for 7.100 that might be fine for the vertical but different for the dipole. The vertical is omni, so at times it would be a better choice than the dipole. Or, perhaps experienced users can tell me that the tuning works quick enough that even if I try to confuse it the KAT500 will be quick enough that it isn't an issue. 73 de Chuck, WS1L -- === Chuck Chandler chandler...@gmail.com === __ 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 Message delivered to arch...@mail-archive.com

For a bit, and that is pushing it. So, I have worked plenty of DX and busted pileups with 500 to 600 watts. It does seem to me that I am often QSY'ing quickly so the amp isn't really peaked up, so half the time it's more like 500 watts out than 600. I am looking forward to building these - I read the manuals and can't wait to dig into them.. For what it's worth, I was quoted a shipping wait of 5 to 7 days at the most. I sure hope none of those pesky KPA1500's delay my toys! I am guessing I will not see much difference between the two amps in terms of effectiveness of the transmitted output signal in actually putting DX in the log, but I wonder what others have observed? 73 de Chuck, WS1L -- === Chuck Chandler chandler...@gmail.com === __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] OK, odd question
Something that bugs me just a tiny wee bit. So, for years I used a Kenwood or two, then a Yaesu or three, then a Ten-Tec. Much of the time on CW. When I tuned a band, say 20M, I would start at the bottom of the band and tune upwards in frequency. When I did this, as I approached a CW signal it would be higher-pitched. As I tuned it to zero-beat with my 500-Hz CW offset the pitch would drop until it matched my 500 Hz spot. If I tuned too far, the pitch would drop below 500, then drop off the scale as I tuned past it. Similar in fashion to tuning a USB signal. My Elecraft tunes similar to one other rig I have owned, an iCom 706 MkIIG. As I tune up the band I first hear a low-pitched CW signal, then it centers, then it gets higher in pitch. Similar to tuning an LSB signal. This doesn't make a difference in usability, I guess it's due to the receiver architecture. And, yeah, I can go to "CW-R" and it works the way all those other radios did. My question is, is there a reason for it working this way? Does it provide some advantage? Or is it just the way it happened. like, not enough room towards the edge of the napkin when it was drawn up? Curious. 73 de Chuck, WS1L Chuck Chandler chandler...@gmail.com __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] KPA500 Info Disappeared From Website
God bless Madelyn. She has the patience of a saint. I was struggling to understand what was included in one of the package deals, so she actually screen-shotted me exactly what I needed to get an order together with all the options, making it so much easier for me to click through and verify I had everything ready to go before I hit the "buy" button.

[Elecraft] K3S and N1MM+ Logger question
I am getting my K3S set up for contesting. So far I have N1MM+ sending CW through the USB control. My question is for setting up voice contesting. I do not have the K3 digital voice option yet but I can see that N1MM+ does interface with the K3S audio codecs. Is there a way to use the N1MM+ software to send audio files over the air, or to use the K3S to record audio files to be saved and sent later? 73 de Chuck, WS1L -- === Chuck Chandler chandler...@gmail.com === __ 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 Message delivered to arch...@mail-archive.com

[Elecraft] Took Some Lightning Damage Last Night
Hi All: It looks like we took an EMP hit at home from nearby lightning just last night. The XYL was up with the baby and said the whole house lit up sometime after midnight. So far, it appears I've lost a TV, laser printer, the shack PC, all the outdoor security cameras, and my internet service. As for radio gear, my Astron VS-35M power supply was showing low voltage output, but a power recycle corrected that. The Elecraft K3 was actually powered off and disconnected from the antennas, but it was throwing errors when I powered it up. I assume that was from the connection to the computer. I did a soft reset and it seems to have recovered, but I need to do more thorough testing. The KX3 was only connected to power and was powered off, and it seems to be OK so far. The other ham radios seem to be OK, except for an old 1990s-era Radio Shack scanner that likely can't be replaced. I may crack that one open and see if there's something obvious that can be repaired. Any advice for what other checks I should perform on my house and equipment (especially my K3 and KX3) to check for hidden gremlins before I start calling the insurance companies and getting the claims process rolling? --- Chuck Milam, N9KY n...@arrl.net __ 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 Message delivered to arch...@mail-archive.com
