For example, following the directions here https://www.windowscentral.com/how-manage-time-servers-windows-10 https://www.thewindowsclub.com/change-internet-time-update-interval-windows or using any number of products such as D4, you can be within 0.01, +- 0.01 s... Windows defaults to syncing time weekly, but I have mine set at hourly. At any time, I can go here https://time.is/ to see how far off I am...is this close enough for FT8? One note I saw said "But if you can get your clock within, say, a half a second, you'll be fine for FT8 and FT4." and this method certainly exceeds that spec. I'm not an FT8 kinda guy, but I ran across this http://www.kk5jy.net/tweaktime/ ~R~ 72/73 de Rich NE1EE The Dusty Key On the banks of the Piscataqua From jd at ko8v.net Tue Dec 1 09:11:26 2020 From: jd at ko8v.net (Joe DeVincentis) Date: Tue, 1 Dec 2020 09:11:26 -0500 Subject: [Elecraft] KX2 & FT8 In-Reply-To: References: Message-ID: <367290F7-8372-45E4-92D0-B884DF3973CC@ko8v.net> These are the steps I usually go through: 1. Ensure PC has an accurate time source. Verify against something like https://time.gov . If the website updates its seconds at the same time as your system from a visual perspective, then you're close enough. 2. If you are using an FTDI based USB to serial converter for CAT control, be sure Serial Enumeration in the advanced properties for the COM port is unchecked (it can do weird things to your system). I also check the box to disable modem control at start up. 2. In the WSJT-X settings ensure that Test CAT and Test PTT work correctly. Be sure that the Test PTT causes the radio to go into TX. I use either CAT control or H/W control for PTT trigger depending on what I can do with the H/W. I generally prefer H/W control. It's faster in the system to flip a bit, then to send a string a bits via the RS232. 3. Setup the Audio in WSJTX to point to the correct devices. 4. In the Windows Sound control panel ensure levels for both Recording and Playback for the device in use for the radio are somewhat reasonable - say 75%. It's just a starting place. Also be sure the devices are not the defaults - that will prevent sounds being sent to the radio you don't want. Can't tell you how times I hear audio play back of either alerts or some streaming media come through. All newly plugged in sound devices are automatically made default by Windows. IMHO, it's a stupid thing for Windows to do and I've never found a setting to prevent that. 5. Check the receive is reasonable in WSJTX - generally between 40 and 60 on the WSJTX meter. Play with settings in the sound control panel and/or the radio until things look right. 6. Set the radio for 0 power and hit the tune button in WSJTX. The radio should go into TX. 7. Using the Sound panel control for the radio playback device, the Pwr slider in WSJTX and/or the radio mic gain, tune until ALC is just starting kick in. On other Elecraft radios, that's usually the 5 ALC bar flickering. I try not to have any setting at the max. If any step is not working, diagnose and fix that step before proceeding. This is what I have found works best for me. Your mileage my vary. 73, Joe, KO8V > On Dec 1, 2020, at 08:04, Mark Moeller wrote: > > I am working to get my KX2 setup for FT8 and appreciate any help. > > My setup includes: KX2 connected to a G5RV antenna, Windows 10 laptop, USB > Sound Card, Mic & Phone cables.

I get fan starting running after 10-15 minutes. However after another few minutes of running the fan will shuts down every time I press a key ( I am CW op). As a result the temperature of the PA goes higher and higher and at certain point the PA shuts down. If I check the temperature reading through temperature calibration in the menu I see that temperature reading jumping force and back with range of readings 10 - 20C. That kind of erratic temp reading continues even when temperature of the heatsink goes down.

I don't need real time "time" for things these days...if I do, I turn to an RTOS...but I am naive in this area. Since reconfiguring my Windows time specs, including not using the windows.time server, I have not seen a time offset exceeding 0.5s...in fact, the highest I recall is 0.3s...that is 10X the error you report for Meinberg I visited the site, and found https://www.meinbergglobal.com/english/info/ntp.htm https://www.meinbergglobal.com/english/sw/ntp.htm#ntp_stable so it appears that there is a software-only solution?

Anyone who has visited it in the past will be saddened to see its condition now. I was there in the 80's. I went on a lark, traveling by "publico" from San Juan where my ship was docked for a few hours. I had trouble even finding the place until I found out it was referred to by locals as "Esperanza radar". The trip and the view were memorable; seeing that gleaming-white symbol of advanced technology filling the valley was so impressive! I used to tell people traveling to Puerto Rico to make sure and see Arecibo.

Here is a brief explanation from my trip notes (we were guests because my wife is an astronomer with many Chinese colleagues). It?s odd that they are creating a tourist destination, since normally such telescopes are located to minimize RFI. ?We were met by a driver from FAST in a Honda Odyssey for the two-hour drive to Pingtang, China?s self-proclaimed ?Astronomy City.? There is a huge amount of new construction, as they try to take advantage of the FAST to create a tourist destination. There are new shops and hotels being built, and on the sides of the roads they even have statues and bas reliefs of famous scientists and scientific instruments. FAST stands for ?Five hundred meter Aperture Spherical radio Telescope,? and that?s just what it is ? outdoing the 300-meter radio telescope at Arecibo, Puerto Rico by far. It?s in a valley that had a dozen or so homes before they houses were demolished. It?s 500 meters across, and is partly steerable, since the panels can be somewhat deformed by 4,000 actuators pulling on cables that tug on the panels that comprise the reflective surface. The receiving ?cabin? is suspended on cables attached to six huge (maybe 350-400 feet tall) towers. So by moving the cabin and pulling on cables, they can apparently track through about 20 degrees, unlike Arecibo, which is fixed in a spherical shape. The actuators that deform the mirror into a parabola are hydraulic and need only pull about a foot and a half or so on each cable. Although it was late, we drove down for a quick look at the telescope, since it wasn?t raining. It?s an unbelievably impressive mechanical construct. 73, andy ae6y Sent from Mail for Windows 10 From: AB2E Darrell Sent: Wednesday, December 2, 2020 8:54 AM To: Elecraft Refl Subject: Re: [Elecraft] Arecibo antenna collapses I From bill at soundbusiness.us Wed Dec 2 12:23:32 2020 From: bill at soundbusiness.us (William Hein) Date: Wed, 2 Dec 2020 10:23:32 -0700 Subject: [Elecraft] K4D questions - diversity, HDMI, Ref In In-Reply-To: References: Message-ID: Wayne, Back to the phase locked receivers in the K4D.

His also mounted an 'expedition' in April 2010 to use the Arecibo Radio Telescope to conduct moonbounce with Amateurs around the world using voice, Morse code, and digital communications. [Wikipedia] The Arecibo radio telescope was used as a powerful radar to study other objects in the solar system. Things at certain distances could not be studied because by the time the transmitted signal reflected back, the Earth had turned enough that the radio telescope was pointed in the wrong direction. It's definitely a sad occurence. I sympathize with the people who use black humor to handle their sadness. 73 Bill AE6JV On 12/2/20 at 8:59 AM, weaverwf at usermail.com wrote: >EME (Earth - Mars - Earth) ? :-) > >73, >Bill WE5P > >Comfortably Numb ----------------------------------------------------------------------- Bill Frantz | When all else fails: | Periwinkle (408)348-7900 | Voice and CW. | 150 Rivermead Rd #235 www.pwpconsult.com | | Peterborough, NH 03458 From k9ma at sdellington.us Wed Dec 2 15:35:39 2020 From: k9ma at sdellington.us (K9MA) Date: Wed, 2 Dec 2020 14:35:39 -0600 Subject: [Elecraft] Elecraft Kit Assembly Message-ID: When assembling the KAT500 kit yesterday, I found it frustrating trying to get the nuts started on the connector screws.

They compensated for spherical aberration by using a travelling wave antenna for the feed, and later by using a series of sub-reflectors, the latter in the gondola. The spherical aberration is independent of pointing direction, which, I believe, is why they went for a spherical, rather than a parabolic, shape. -- David Woolley On 02/12/2020 17:22, Andrew Faber wrote: > So by moving the cabin and pulling on cables, they can apparently track through about 20 degrees, unlike Arecibo, which is fixed in a spherical shape.

What I took away from it was that the future of radio astronomy lies in VLBI arrays rather than wide-diameter dishes, and that for economic as well as electronic reasons the direction is toward more numerous much smaller antennas and lots of enhancements in data processing. In response to a question I put during the Q&A, the presenters' answer was yes, that direction in radio astronomy's evolution will increase the potential for amateurs to contribute to the kind of research large dishes have been doing. I too regret the catastrophe at Arecibo. In fact, I took the occasion to rewatch "Contact," in which Ellie Arroway as a young girl, signing W9GFO and frustrated at her inability to reach her father on (I assume HF) SSB said wistfully, "I need a bigger antenna." The next scene was the more mature Ellie standing at the edge of Arecibo. But despite the loss of a legendary facility, if what I heard at the SETI event was correct, there will not likely be any serious effort to rebuild it.

It might not be re-built in Puerto Rico due to exposure to Hurricanes and encroaching civilization threatens the radio quiet area for useful radio astronomy. Wonder if a new site might be chosen (someday)? I copied the 432 MHz SSB signal from Arecibo using my 16-foot dish and a hastily made 432 feed. I tried sending JT65 signals at 100w but never got a reply. In my college years radio astronomy was one of my career choices and I even got an invite to do Master's study at Ohio State with Dr. John Kraus-W8JK (who built the "Big Ear" radiotelescope). But was not to be - I moved to LA in Nov. 1968 to start work with Hughes Aircraft on military projects. (don't ask) Later in 1972, I did some minor radio astronomy using a 26m dish at Goldstone. A lot of neat science was done at Arecibo. Always wanted to visit (too late now). I did get to see the Big Ear about 3-months before is was torn down to build a golf course. This where I could make a political joke (but won't). 73, Ed - KL7UW Date: Wed, 2 Dec 2020 14:51:02 -0500 From: Bill Frantz To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Used antenna - Arecio antenna collapses There are some interesting tidbits about Arecibo: Joe Taylor, K1JT, or wsjt-x fame, did some of the work that lead to his Nobel Prize at Arecibo. His also mounted an 'expedition' in April 2010 to use the Arecibo Radio Telescope to conduct moonbounce with Amateurs around the world using voice, Morse code, and digital communications. [Wikipedia] The Arecibo radio telescope was used as a powerful radar to study other objects in the solar system. Things at certain distances could not be studied because by the time the transmitted signal reflected back, the Earth had turned enough that the radio telescope was pointed in the wrong direction. It's definitely a sad occurence. I sympathize with the people who use black humor to handle their sadness. 73 Bill AE6JV 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From wes_n7ws at triconet.org Wed Dec 2 19:02:18 2020 From: wes_n7ws at triconet.org (Wes) Date: Wed, 2 Dec 2020 17:02:18 -0700 Subject: [Elecraft] Arecibo antenna collapses In-Reply-To: <20201202172319.627D2149ADD8@mail.qsl.net> References: <20201202100626.Horde.B1N3Ax8XNwP-kPthd0AW6XO@www11.qth.com> <7A799BCC-25D7-46ED-AD11-5601B7F048FA@gmail.com> <20201202172319.627D2149ADD8@mail.qsl.net> Message-ID: <1d9baef5-7f99-fee7-4e51-4e9b614edba0@triconet.org> Did they show you the transmitter?

There is a huge amount of new construction, as they try to take advantage of the FAST to create a tourist destination. There are new shops and hotels being built, and on the sides of the roads they even have statues and bas reliefs of famous scientists and scientific instruments. FAST stands for ?Five hundred meter Aperture Spherical radio Telescope,? and that?s just what it is ? outdoing the 300-meter radio telescope at Arecibo, Puerto Rico by far. It?s in a valley that had a dozen or so homes before they houses were demolished. It?s 500 meters across, and is partly steerable, since the panels can be somewhat deformed by 4,000 actuators pulling on cables that tug on the panels that comprise the reflective surface. The receiving ?cabin? is suspended on cables attached to six huge (maybe 350-400 feet tall) towers. So by moving the cabin and pulling on cables, they can apparently track through about 20 degrees, unlike Arecibo, which is fixed in a spherical shape. The actuators that deform the mirror into a parabola are hydraulic and need only pull about a foot and a half or so on each cable. Although it was late, we drove down for a quick look at the telescope, since it wasn?t raining. It?s an unbelievably impressive mechanical construct. > > 73, andy ae6y From edauer at aya.yale.edu Wed Dec 2 19:13:28 2020 From: edauer at aya.yale.edu (edauer at aya.yale.edu) Date: Wed, 2 Dec 2020 17:13:28 -0700 Subject: [Elecraft] Arecibo Message-ID: <007801d6c909$20ceca00$626c5e00$@aya.yale.edu> A postscript to my previous post -- the SETI discussion titled "Radio Astronomy: The End of Big Dishes?

What I took away from it was that the future of radio astronomy lies in VLBI arrays rather than wide-diameter dishes, and that for economic as well as electronic reasons the direction is toward more numerous much smaller antennas and lots of enhancements in data processing. In response to a question I put during the Q&A, the presenters' answer was yes, that direction in radio astronomy's evolution will increase the potential for amateurs to contribute to the kind of research large dishes have been doing. I too regret the catastrophe at Arecibo. In fact, I took the occasion to rewatch "Contact," in which Ellie Arroway as a young girl, signing W9GFO and frustrated at her inability to reach her father on (I assume HF) SSB said wistfully, "I need a bigger antenna." The next scene was the more mature Ellie standing at the edge of Arecibo. But despite the loss of a legendary facility, if what I heard at the SETI event was correct, there will not likely be any serious effort to rebuild it.

I don?t know what it would cost, but consider that one Virginia-class submarine costs well over $3B. We build those, even if it is in small numbers.

I believe they'll fit a wide range of popular headphones. They were very comfy to wear for 32-33hrs this past w/e but of course I can't say how they'll be 6 yrs from now. They are some kind of velour(ish?) fabric with a PU leather (leatherette) piece that wraps around the actual plastic speaker grill. Not especially easy to install (no pads will be for that matter) but totally doable. Me, still smilin' ~24hrs before CQWW CW..but pretty tired by Monday @ 0000z (and not smilin')(ok, pic didn't show but for you CWOps, it's on a thread there) Yes, red on black is a bit weird. Whatev's..hi.they do fit a bit better than the pic indicates..I was just doing a quick selfie for my wife (who was at work) when I told her I put red pads on black phones. For the real radio operation, I adjusted the headband better and these fit completely over my ears and against my skull (for lack of a better description). They are a titch thicker than stock. Again, for CWOps.pix came through there OK.

PC remote user software interface. There are some third party solutions available but that did not interest me. I cancelled my early pre-order and received a refund. I?m sure they will eventually develop the software for full remote connectivity, but I expect the focus was on getting the radios out the door. I am 100% remote operation and I have the K3s-K3/0 mini setup with the remoterig boxes, but my main radio of choice is now the Flex 6600. I am a low-band 160m CW op mostly. I love the K3s for its weak signal CW capabilities, but the Flex 6600 is much more ergonomically friendly and the waterfall/spectra display is too much to give up. I will never go back to using a radio without a pan-adapter. I will be the FIRST in line for the K4 when they develop a PC based user interface that emulates sitting at the radio like the Flex does. But I will need to see it first. Here is a YouTube video I made showing my control operating position, and I talk about the benefits of the Flex PC software compared to operating the K3 with the remoteRig boxes. https://youtu.be/fd6DkobdlK4 Here are some other videos I made showing other aspects of my remote set-up: https://www.youtube.com/playlist?list=PLipJSm0KKo3Am6fTn5MllmAO0Ivj23SS1 73, de steve ve6wz > On Dec 3, 2020, at 12:39 PM, David Winarsky wrote: > > Hi folks, I?m wondering whether anyone has an update or insight into the plans with the K4 and remote operation?

I?ve already swapped the KXUSB cable with another one (home-brew) so I?m pretty sure it?s not the KXUSB that?s gone kaput. And the PC is doing USB comms fine (e.g. the USB interfaces to my K3), so I guess it?s not the PC or the USB port either. I?m contemplating trying a KAT500 factory reset. But two questions arise: 1. Can I do a factory reset without having the serial comms working (so: can I do a factory reset other than from within the KAT500 Utility)? 2. What antennas are enabled after a factory reset? (Question 2 is because I have multiple antennas connected to the KAT500, and if the factory defaults would be that only ANT1 would be enabled, I would lose functionality until I?ve got the KAT500 repaired?)

Then go have a cuppa.? When you get back, plug the power in and restart it and test. I have found that some devices (more in the USB realm) occasionally 'stick' when exposed to RF and that a long power removal is the only cure.? If it's a frequent event, you have an RFI issue to deal with (better grounding and bonding is the first place to start for that). GL, Rick NK7I On 12/4/2020 8:22 AM, Frank R.

When not in test tried with wsjt-x through a signal link as I had been using it for months on 1o,12,15,17,20,and 40 meters. I was using it and everything was fine. Until about 10:00 yesterday. Checked so cables between te radio and amp. Then I realized I did not have even the drive to the amp. Absolutely 0 watts. I was driving the amp with about 8 watts. Then I decided to make sure nothing external was affecting the radio so I disconnected everything except power and antenna cable to wattmeter and dummy. Still zero. When you depress the XMIT button on the radio it switches automatically to CW and transmits a carrier normally. It switches to cw but still no RF out . Displays dashes for SWR and 0 watts. Hooked a mike up changed settings. I can see the ALC change but still nothing out. Tried high power a day low so it is in the drive I believe as the 100 watt amp is the same results as the 10 watt.

Message-ID: "2. What antennas are enabled after a factory reset?" On all bands ANT 1, 2, and 3 are enabled and "preferred" is set to "last used" I don't know what the Utility sends for "Reset Configuration". The documented reset command is: RSTx (Reset, SET only) SET format: RST0; or RST1; RST0; resets the microcontroller without saving state in EEPROM. This is equivalent to removing the power plug and plugging it back in again. RST1; simulates pressing the power off button which saves current state in EEPROM before reset. RST may be ignored while transmitting. Neither RST0; nor RST1; appear to clear the memorized settings so I suspect the Utility uses another command.

If you can hear audio getting to the radio, then another worthwhile test is to try 5-10 watts output. This will use the low power amplifier in the radio, skipping the 100W amp.

TUNE produces a tuning signal, power set by the user. Used for many things eg. tuning linear, external ATU. ATU TUNE works with internal ATU. XMIT puts the K3 into TX without any output until you either key or apply audio, be it speech or audio output from the PC.

For instance, SGC makes "smartuners" that can be remotely mounted from your transceiver. These tuners work automatically to tune the antenna when a transmission occurs. The long press on the XMIT button function transmits a low power continuous tune sufficient to activate the SGC tuner's tuning function. The ATU tune works with the internal tuner. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Rick NK7I Sent: Friday, December 4, 2020 10:15 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] k3 no RF in transmit You've made a mistake, a long XMIT (TUN) press is for applying a small amount of output, to match with the antenna (or check the SWR).

For instance, SGC makes "smartuners" that can be remotely mounted from your transceiver. These tuners work automatically to tune the antenna when a transmission occurs. The long press on the XMIT button function transmits a low power continuous tune sufficient to activate the SGC tuner's tuning function. The ATU tune works with the internal tuner. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Rick NK7I Sent: Friday, December 4, 2020 10:15 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] k3 no RF in transmit You've made a mistake, a long XMIT (TUN) press is for applying a small amount of output, to match with the antenna (or check the SWR).

"2. What antennas are enabled after a factory reset?" On all bands ANT 1, 2, and 3 are enabled and "preferred" is set to "last used" I don't know what the Utility sends for "Reset Configuration". The documented reset command is: RSTx (Reset, SET only) SET format: RST0; or RST1; RST0; resets the microcontroller without saving state in EEPROM. This is equivalent to removing the power plug and plugging it back in again. RST1; simulates pressing the power off button which saves current state in EEPROM before reset. RST may be ignored while transmitting. Neither RST0; nor RST1; appear to clear the memorized settings so I suspect the Utility uses another command. Now I may have to find out what that is .... 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at 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 dick at elecraft.com From alan at wilcoxengineering.com Fri Dec 4 13:57:48 2020 From: alan at wilcoxengineering.com (Alan D.

With no USB cable connected and the KAT500 powered up, the Q1 drain voltage is 2.39V, where I would expect 5V. Also the gate voltage is 2.30V, where I would expect it to be floating. With the power off, I?ve measure the drain-gate resistance. It?s 5.5 k ohms. Oops! My conclusion must be that Q1 has failed. So now I?m about to learn how to SMD components, hi hi.

Once again I opened it up and re-installed the K60XV board. I put a scope probe on P1 pin 6. I did not see the AGC failure mode right away, but I did find an intermittent oscillation on pin 6 at about 15 MHz. It would come and go, but no AGC activation. I removed the board and re-soldered all the components around the LM358. Then I inspected the board and scraped away any residual solder flux in that area of the board between any pins. I also re-soldered the 4.0 MHz resonator, although I did not hear or detect any relay activation when it failed before. After that, I put the board back in with the scope probe and ran it on the workbench for a day. I saw no AGC failure mode and no more 15 MHz oscillation. So, maybe it is fixed?

Unfortunately, that is not possible. I've been working with Linux for decades now. Unfortunately, they sometimes change stuff in the kernel that you never even guessed would change that breaks your code. It's the way it is. Sometimes it is for security reasons. It's just a cost of using Linux. Windows, IOS are no different. Stuff breaks all the time. At least with Linux you can look at the source code to see exactly what changed and how to fix your code. I expect Elecraft will get it sorted out quickly.

This however now brings up the question of what happens if Elecraft goes out of business. Hopefully not, but it has to be looked at... They could then Open Source the code for the rig at that point... Maybe put the source in escrow now, against that eventuality, and keep the escrow updated with current code... 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst.

Then there are files that constantly seem to update (i.e. the time zone files are a constant state of update; who knew it was so tough to figure zone changes?). And there may be improved drivers for the hardware, which may break things relying on eccentricities of the old driver...? Or drivers for new hardware since the last release instead of the generic driver that was used. I randomly update my linux machines, no pattern at all but months apart is a fair guess.? They don't have many ports or services available so while they're still attacked, so far, there haven't been any successful break ins.? I also split the duties to various computers around the house (the router knows all and puts one linux box in the DMZ and it's secure enough to handle it).? Without knowing what I did, the end user doesn't have a clue what machine or OS I'm using. Sometimes even the version (and support) have had a major update, which may change a lot of things in one pass. That's not always good. Often the audio breaks because the app used to manipulate or process the audio is deprecated; so scripts or similar that call the apps must be adapted... It's an evolving OS as any other, which means changes. I'm sure Elecraft will stay on top of it.? Keep the faith.? Their name and rep is on the line and they treat things in that manner. 73, Rick NK7I On 12/6/2020 4:49 PM, Fred Jensen wrote: > Was wondering that myself, Carl.?

Message-ID: I?ve been using RemoteTX for my remote operation for a while now. With the 7300 it worked just fine using the USB port for audio and control. I switched over to use it with my K3S and it seems to work differently in one strange annoying way. The audio coming over the USB line is constantly monitored and sent to me over RemoteTX. Even during transmissions. Unlike the 7300, I?m getting an echo of whatever I?m saying. And, of course, it?s delayed to make it even harder to talk. ;) Now, if I connect to the rig using an external sound card and the line in and out on the back, it works fine, as long as I have the Monitor turned down to zero. What it sounds like is that there is a ?monitor? function going on when I use the USB connection. Does anyone know anything about this? Like a secret menu/button that I?ve missed to adjust a ?monitor? function on the USB connection. Or some blatantly obvious paragraph in the manual, that is probably in bold, that I can?t seem to find? And yep, I could just do the external sound card, but hey, it?s more fun to make things work, right? ;) Be safe all!

See this link on my QRZ.COM page : - How to get clean fast CW from an Elecraft K3 without using CW QRQ mode (post to Win-Test Reflector, November 14th, 2013) This was before the KSYN3A upgrades, which only helped the keying problem a little. Element shortening is still there, and bad CW jitter is still present in the K3 + KSYN3A at speeds above 37 WPM with external keying. The internal K3 keyer sounds fine (it compensates), but external keying is a problem. With VOX ON (QSK or semi-breakin), no PTT input, all keying elements are shorted by the TX DLY. The default TX DLY nor 008 is really closer to 6 ms delay, after you get the KSYN3A upgrade, hence 6 ms of keying compensation required. A high TX DLY for a slow amp. relay makes the problem much worse. Keying Compensation is unfortunately not available in N1MM+ when using the convenient DTR and RTS CW keying over the K3 serial port or the K3S USB cable (CONFIG:PTT-KEY RTS-TR), but it should be added IMHO. This feature is already available in Win-Test. More details and other fixes (e.g. use software generated PTT, no keying compensation) are found in that post above. The K4 has NO CW jitter problems that I've found, but element shortening by TX DLY is still present, and I've filed bug reports about it, but it's not at the top of their list yet. 73, Bob, N6TV K4 Field Tester On Sun, Dec 6, 2020 at 2:01 PM Dave Hachadorian wrote: > Bingo!

You are looking in the right place, in my opinion, with Siglent, Rigol, etc. Another brand to look for is Hameg. They all offer lots of features and value for the $$. Great buys on Spectrum Analyzers there also, by the way ;>) Back when I had my lab I had Agilent scopes, but if I were doing it over today, I?d go with something like the above. If you aren?t familiar with it, check out Dave Jones?s EEVBlog podcast. He has dozens of detailed reviews of these scopes which include HD Video teardowns of the internals as well as analysis of the circuitry. Should be available at your favorite source of podcasts. Happy Shopping ! 73 Craig AC0DS From kd4iz at frawg.org Tue Dec 8 15:47:10 2020 From: kd4iz at frawg.org (kd4iz at frawg.org) Date: Tue, 8 Dec 2020 15:47:10 -0500 Subject: [Elecraft] KXPA100AT with non-Elecraft transceiver weird issue Message-ID: <074501d6cda3$4dd55c00$e9801400$@frawg.org> To the group amplifier gurus: I have been (happily) using an IC-705 to drive my KXPA100AT or my KPA500 with virtually no problems for about 2 months now. Set up is an IC-705 driving either a KXPA100AT or a KPA500. The keyline to the amplifiers is a 1/8" stereo plug cable from the send/alc jack of the rig to an RCA plug on either amp. Mostly use other radio combinations, but occasionally I use the 705 plus amplifier combinations for simplex D-Star over HF (DV mode). The sole issue that has popped up is when using IC-705 for HF D-Star with the KXPA100AT (regardless of rig frequency). In DV mode and only when I have a transmit message set, on the initial key up the rig goes into continuous repeated transmit. This can only be interrupted by pulling the key line to the amplifier or shutting the rig off. When I disable the TX message, the rig and the amplifier behave normally in DV mode. The KPA500 does not exhibit this behavior. I would love to know what is going on here. Is it something which transmitting more data than the normal ID data packet that goes with D-Star voice data causes? It would seem so, but why does the combo continue to cycle into TX when the data is already sent? Truly odd, but fortunately I can avoid the problem by remembering to turn off the TX message. When the TX message is off, the amplifier behaves like a gem. The KXPA100 switching circuit is likely pin diode based as no relay sounds can be detected. This is not made clear in the Theory of Operation section of the user's manual and since there are no circuit diagrams provided, that can't be verified. I am forwarding this to Elecraft Customer Service as I understand that I will not be the first to make the observations. Thanks for the bandwidth!

I've owned gobs of Icoms and Yaesu's, so the Elecraft controls are pretty foreign to me. I do own a K3 but have quite literally used it 3 times in the 6 or whatever years I've owned it. It's packed away. I've looked in the 2 books I've rec'd but it doesn't spell it out "exactly" and maybe I am just being daft. I';m off work today, under the weather, so not firing on all cylinders.(hi) I am wondering about the various filter widths and how to adjust. It almost seems like it goes to FIL 1, 2 3 automatically as I adjust the PB tuning,. IS THIS THE WAY FILTERS WORK? In my Icoms (hope that's not a dirty word here), I have to purposely select individual filters with a button press or two or three as it cycles through them. It's been so long since I used my K3 (3-4 yrs?) that I don't even recall how it's done, but my sense was that it was different on the K3. Thanks for answering this obviously very basic question. I don't have a good way to set up and operate in the tiny shack, but I may try to put it on a wire in the livingroom later this month and familiarize myself with some settings on these Elecrafts. Posted below was the sale ad I bought it from. 73 Mike VE9AA KX3 for sale serial number 1900 from a non-smoking and no pet home. The Latest firmware installed.

It would have even been useful to set the date and time each time I start the scope. But I have a GREP utility that handles many of my file naming needs, and immediately after storing images on a thumb drive, I put the drive in the laptop and run the grep util. It renames the files to Rigol DS1202ZE nn yyyymmdd hhmmss (24hr), using the laptop date and time, so they are not too far off. ~R~ 72/73 de Rich NE1EE The Dusty Key On the banks of the Piscataqua From kevin at ve3syb.ca Wed Dec 9 14:04:12 2020 From: kevin at ve3syb.ca (Kevin Cozens) Date: Wed, 9 Dec 2020 14:04:12 -0500 Subject: [Elecraft] Oscilloscope recs In-Reply-To: <20201209170944.8F7AF149A8D9@mail.qsl.net> References: <1179791941.3659370.1607456390945.ref@mail.yahoo.com> <1179791941.3659370.1607456390945@mail.yahoo.com> <176450a07f0.2852.96e80410205cf590e45b6250d389e5fb@w8fgu.com> <000601d6cdce$63da3450$2b8e9cf0$@comcast.net> <1146930757.3829068.1607524834802@mail.yahoo.com> <7961e546-db2a-6728-a135-1da1da9fbf49@kn5l.net> <20201209170944.8F7AF149A8D9@mail.qsl.net> Message-ID: <6b37cbb4-462e-5632-3396-727bcf1f4ab9@ve3syb.ca> On 2020-12-09 12:07 p.m., Rich NE1EE wrote: > On 2020-12-09 09:37:-0600, John Oppenheimer wrote: >> Hi Lou, >> Rigol DS2202A has time in saved image.

I also prefer using a proper scope with a display, knobs, and buttons. Space on my workbench is at a premium. The only computers I have near my bench are a Pi 3 and a Pi Zero W. The monitor sits on a nearby shelf that. I just checked and if you do have a nearby computer and you connect it to the Rigol you can set the date and time using SCPI commands. BTW, I checked the other day and the web site for getting the keys to enable features in the Rigol is still up. Using it would probably void the warranty. Your best bet is to get the scope around Black Friday or Cyber Monday when the keys for all the features are provided by the seller. -- Cheers!

A Siglent SDS1202X-E is my all-purpose digital scope. There's a large user community, and a lot of info on getting up to speed with it. I like capabilities such as capturing screenprints containing a lot of data overlaying the waveform graphic. I got a PicoScope (USB) when I was setting up my K3S for 630m last year. With a simple interface, the PicoScope can be a handy way of checking the phase of the voltage and current of the tx amp's output in order to match the antenna as precisely as possible. With remote access software (NoMachine in my case, TeamViewer is also widely used), the scope's display can be viewed in real-time on an Ipad outdoors. My frequency measuring Elmer, who is old school, uses an analog scope set in XY mode to watch the rotation of a Lissajous pattern. He persuaded me that an analog scope is better for this purpose than a digital one -- screen movement on the latter is in small but discernible steps, while motion is smoother on an analog scope. So I picked up a vintage Tektronix T922 for this admittedly niche purpose.

You do not want any of the levels to be too near either end of the scale for best linearity. So my mic level usually ends up at 20 to 30.

When I used that combo, the amp sat on the tuner, no issues. However, it's in your better interest to allow nothing atop the K3 AND the KPA to optimize cooling. If you MUST stack them, shim (along the side edges) them to allow for 3+ inches of clearance to allow for heat dissipation (venting for the fans).? Again, that's not the best situation and should be avoided.? (K3 on the bottom for easy control access, SHIM, KAT, KPA) As said; you WILL have a mess of cables to address as well, RF, ACC, serial lines, power...? confining that to a small space rarely goes well (pull on one, five more follow). I'd suggest serious thought to come up with a better arrangement.? If you use computer control and logging, the KPA/KAT combination don't have to be visible (just allow for cooling), and within no more than 6' of ACC cable away from the K3...? The computer can change modes, trigger tuning etc. via the utility apps (saves a long reach too). GL es 73, Rick NK7I On 12/11/2020 2:07 PM, Jim Rhodes wrote: > That is how I would do it.

It is an outstanding station and it is a pleasure to operate. I would however, like to improve the operation by incorporating band switching and frequency tracking. We built an Arduino based converter to convert the ICOM CI-V serial data to Kenwood compatible RS232 serial data. This data feeds both the tuner and the amp which both switch bands. I can also hear the tuner switching band segments as I tune the VFO across a band and I learn frequencies in each segment. This setup is working well except I was hoping that it could emulate some of the descriptions in the Elecraft videos of the tuner and amp with a K3. Specifically when going back to one of the previously learned band segments, the transceiver still calls for the short burst of RF prior to transmitting at full power. The videos and manual description implies that the K3 and possibly Kenwood and Yaesu transceivers, will be tracked by the KAT500 and NOT require that short burst of RF. Is there a configuration in the Utility program that will allow tracking on a non-K3 transceiver? Is there something specific in the K3 (the tracking function on P28 of the manual) that enables this feature to NOT require the short burst on a previously learned frequency? * From a.durbin at msn.com Fri Dec 11 19:30:32 2020 From: a.durbin at msn.com (Andy Durbin) Date: Sat, 12 Dec 2020 00:30:32 +0000 Subject: [Elecraft] KPA500 and KAT500 Enhanced mode frequency tracking Message-ID: "the transceiver still calls for the short burst of RF prior to transmitting at full power."

The Rigol websites https://rigol.force.com/support/s/ https://rigol.force.com/support/s/article/DS1202Z-E-Unable-to-Connect-to-UltraScope suggested to me that I needed Ultrascope for DS1000E Series.zip It would not connect.

Another round of spin the wheel at Rigol turned up this trio UltraScope(PC)Installer_00.01.01.07.zip UltraStation setup.zip Ultra Sigma_00_01_06_01.zip No notes about which to choose or why. I started with the UltraStation setup.zip. It seemed to be headed in the right direction. I edited the Init file as suggested. Not sure if I needed to, but figured it could not hurt. I downloaded MSO1000Z_DS1000Z_ProgrammingGuide_EN.pdf and there found this "(5) Control the instrument remotely Right click the resource name "MSO1104Z (USB0::0x1AB1::0x04CE::DS1ZD170800001::INSTR)" and select "SCPI Panel Control" to turn on the remote command control panel through which you can send commands and read data." the same r-click shows Options, which you can follow to a Print Screen button. For me, by default, it saved the screen in bmp, jpg, and png. At last I was on my way... Clicking the wrench gets you eventually to a place where you can save the screen. But that did not work. Ultrascope never did work, though after installing the NI package and UltraStation, it would then connect. As soon as I try to use it, it disconnects. It will connect again, but with the same result. I don't see a command or a way to change the date on the DS1202 yet, but with this method, it is not needed. I will also explore downloading data files using UltraStation. If you want to contact me off list, that is fine. I also found a firmware update, and checking, found that my scope was slightly out of date. I followed the directions and upgraded.

A more accurate term is non-resonant end-fed antenna. Avoiding half-wavelengths means the impedance will not be 5000 ? or greater, but it will be pretty high. Or low. The SWR on the feed line will be large and a high impedance feed point is pretty sensitive to surrounding objects (capacitance). So: 1. Keep the coax short and low loss. 2. At the antenna, connect some sort of counterpoise or RF ground to the shield of the coax. This can be a ground rod, a radial system, or a wire laying on the ground. If you don?t do that, the RF ground will be the coax and everything connected to it, including your K3. 3. After that, tell the ATU to tune it and wait for it to find a solution. 4. If it won?t match, change something. Maybe the length of the wire, maybe the position, maybe the counterpoise. If this is a long-term setup, a common mode choke near the rig is a good idea. Even with a counterpoise, some of that RF energy is going to be on the shield. For field deployments with the KX3, I run with no feed line at all. The antenna wire and counterpoise wire are connected directly to the KX3 with a double binding post adapter. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Dec 12, 2020, at 9:41 AM, Mister Mike wrote: > > What is the best way to do this?

The relays will clatter a bit, and you'll see the displayed SWR ratcheting down, maybe up for short time, as a tuning solution is searched. If the SWR isn't low enough for your tastes, press the ATU TUNE button again within 5 seconds of the conclusion of the previous attempt's end, and the ATU will try again, often with slightly improved result. Don't be surprised if you experience RF gremlins in your shack with a random length wire without a counterpoise.

They make excellent autotuners designed to be mounted outdoors at the antenna. The site includes a number of guide articles and manuals with a wealth of information. These tuners are fully automatic in that when you first transmit on a frequency the tuner automatically tunes and puts the setting for that frequency in memory. When operating these with the K3 you use the tune button (long press on the xmit key) and watch the SWR go down as the unit tunes. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Mister Mike Sent: Saturday, December 12, 2020 9:42 AM To: elecraft at mailman.qth.net Subject: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

For end fed random wires, avoiding wire lengths close to multiples of 1/2 wavelength should be safe with the K3 tuner. 73 Frank W3LPL ----- Original Message ----- From: "Mister Mike" To: donovanf at erols.com Cc: elecraft at mailman.qth.net Sent: Sunday, December 13, 2020 1:04:26 AM Subject: Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

But considering all the pluses and minuses, wouldn?t it make more sense to use a OCFD and not worry about ground rods, counterpoise needs, high SWR, high voltage and currents in the tuner? A well designed OCFD with correct Balun plus a common mode choke at the feed point and another at the radio will cover 80M - 10M with much less than a 10:1 SWR. A matched condition exists only between the ATU input and the PA output. The output voltage or current can be all over the place, including inside the ATU circuits. And the ATU has a 10:1 matching range of 5 ohms to 500 ohms. Random wires can easily be outside of this range. Thus the ATU can not effectively match the load.

The issue was that even though I successfully incorporated enhanced mode frequency tracking from the IC7300 to the KPA500 and KAT500, the radio was keying a x0mS burst of RF even though the frequencies were previously 'learned'. I kept looking into the Elecraft setups, manual, programming and my converter setup. The problem however was in a long overlooked menu setting in the 7300! Sometime in the past I had set "SET, CONNECTORS, FUNCTION, TUNER, PTT Start", to ON which initiates a tuning cycle to the tuner every time the VFO moves more than 1 kHz. Duh. I've been looking for this for days. I switched it to OFF and the frequency tracking works flawlessly. In summary, I have the the IC7300 REMOTE serial data connector feeding an atmega328 microntroller (RX) developed on an Arduino Uno. The code is based on an open sourced Band Decoder by the talented guys at remoteqth.com. The TX data is now in the serial format emulating Kenwood transceivers. This data is converted to RS232 and feeds both the KPA500 and KAT500. The KPA500 menus must be configured to accept SERIAL data at the correct baud rate that the converter code and IC7300 is set to. In my case I am using 4800 baud. Although not necessary to go faster, I may try to go up in steps to the 19200 upper limit of the 7300. *Using this setup, the KPA500 switches bands as the IC7300 QSYs and even more importantly, the KAT500 senses the 7300 frequency and switches to the learned LC combinations for those band segments. This is now done WITHOUT having to send a burst of RF to the tuner to tell it what band and frequency segment we are now operating on.

As I recall, one release a few years back stated that it will handle the parting of an antenna wire while transmitting at maximum output. We can assume that a non-resonant antenna is not cause for concern. There's not much point in having an ATU if it can only be used with resonant antennas. But as someone else has mentioned-- choose an optimal "random" length so as to get a good match on multiple bands. 73, Drew AF2Z On 12/13/20 02:12, David Gilbert wrote: > > Seriously???

What you need is an open circuit on receive and a short to ground during transmit.

The KAT3A does not have a lower power rating for larger SWRs. That would indicate that it can handle the rated power over the entire rated SWR range. If extreme SWR at full power would exceed the component ratings, the specs would say that. This is the entire set of specs for the KAT3A: ? Maximum impedance match: 10:1 SWR ? Maximum power handling: 110 watts https://elecraft.com/collections/kat3a_model/products/kat3a-100w-atu I just curious why people would think that Elecraft publishes specs that their equipment does not meet. That is a pretty strong accusation. No, I didn?t check out TLW, but I have a solid understanding of transmission lines and conjugate matches, even though I only got a B- in my fields and waves class at Rice. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Dec 12, 2020, at 11:12 PM, David Gilbert wrote: > > > Seriously??

In-Reply-To: <92FDAEB8-3788-4CF8-B2E7-728CB91C7A08@wunderwood.org> Message-ID: <560788123.6583120.1607887193496.JavaMail.root@starpower.net> Examining the KAT3A circuit board, I doubt it can handle more than 1000 volts that a worst case random wire -- or a fault -- could cause at the output of the KAT3A tuner when the K3 is producing full rated output. But its unlikely that the KAT3A can produce full rated K3 output because of inevitable low tuner efficiency at high VSWRs. I've never connected an antenna with a greater than 10:1 VSWR to my KAT3A tuner. I would never intentionally do that because of the stress it would could cause to the tuner components from high voltage and/or high current and inevitable poor tuner efficiency when feeding very high VSWR. Hopefully the K3's very fast acting excess VSWR detection turns down its output power before damage occurs. The K3's excess VSWR protection is very effective at preventing damage when the tuner is off. A better solution to extreme VSWR that can be caused by a truly random length antenna is to use one of the proven commercial multiband wire antennas. Just one example of a simple eight band wire antenna that definitely will not damage a K3: www.dxengineering.com/parts/pez-ef-allbandkw 73 Frank W3LPL ----- Original Message ----- From: "Walter Underwood" To: "Elecraft Reflector" Sent: Sunday, December 13, 2020 6:45:34 PM Subject: Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner?? I think you just proved my point. The KAT3A does not have a lower power rating for larger SWRs. That would indicate that it can handle the rated power over the entire rated SWR range. If extreme SWR at full power would exceed the component ratings, the specs would say that. This is the entire set of specs for the KAT3A: ? Maximum impedance match: 10:1 SWR ? Maximum power handling: 110 watts https://elecraft.com/collections/kat3a_model/products/kat3a-100w-atu I just curious why people would think that Elecraft publishes specs that their equipment does not meet. That is a pretty strong accusation. No, I didn?t check out TLW, but I have a solid understanding of transmission lines and conjugate matches, even though I only got a B- in my fields and waves class at Rice. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Dec 12, 2020, at 11:12 PM, David Gilbert wrote: > > > Seriously??

For example, for the KAT500 has a max power rating of 1000 watts into a 3:1 SWR but only a 600 watt rating into a 10:1 SWR???

Virtually none.? 100W most radiated, leaving very little heating the ice/snow along your long cold wire. The wire itself won't heat up as it has very low resistance. 2. IDK about the KXPA100, but Tune is often done at low power, so if 100W work, Tune certainly won't. 3.? Need to check the SWR, but even if good initially, may vary a lot as ice/snow situation changes. This might test the SWR capability of the tuner and protection of the amp, which is best left untested. If you do try it, keep it legal: Check the freq before transmitting, and be sure to identify.? Let us know how it goes. This might be the excuse you've needed to get that legal limit amp you've been wanting.

In fact, just a couple weeks ago we had a very heavy frost. My 360 foot EDZ (dipole) which is normally nearly invisible, suddenly looked like a 2" white PVC pipe. It sagged, but not much. A couple hours' worth of sunlight and a few pops of wind, and it was all good. Your situation is a bit different, but I've never found that transmitting did much to ice. Or to the little birdies who like to sit on the wire (mostly hummingbirds). That being said, unless you have a steel roof, I don't think it would hurt to try. Ease up on the power just in case. But first try receiving. I doubt there will be much degradation from the ice. 73 Lyn, W0LEN -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of David Haines Sent: Sunday, December 13, 2020 12:39 PM To: elecraft at mailman.qth.net Subject: [Elecraft] Ice on dipole under snow under ice Before I try something crazy, like climbing up on the roof ... .

I recently read a comment about the fact that QRQ cannot be used when the K3 is operating in RIT, XIT, or split, nor with DSP shift. Because I believe, though I am not certain, that the discussion was about whether this incompatibility exists in the K4, I was curious about why it matters. When the K3s came out, and the new synths were made available for the K3, QRQ was no longer necessary for even very high CW speeds. If that is so, why would there be a question about such a limitation on QRQ in the K4? Does QRQ mode have advantages beyond the fast QSK now built into the SOP system?

If you only tap the button, even though the display reads "Manual" and the icon appears, it is not really in the manual notch mode. For example, my CW sidetone pitch is set to 560 Hz. If I tune a carrier to 560, and fully engage the notch mode, I can completely null a carrier when I tune VFO B to 560 Hz. The other clue: If you only tap "NTCH", adjusting VFO B only displays frequency, whereas pushing and holding will cause VFO B knob to display the notch filter frequency. Hope this helps. 73, Jim - WS6X -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Bernie and Cheryl Sent: Wednesday, December 16, 2020 1:16 AM To: Elecraft at mailman.qth.net Subject: [Elecraft] K3s Notch Filter Dear Folks: I have a question about use of the Notch filter on my K3s.

At a couple of different QTHs I had my antennas in the attic;? 40-10m dipoles, 6m and 2m loops.? These were wood roofs with cedar shakes or asphalt shingles.? They all worked well when the roof was dry.? Wet definitely affected the SWR.? A wet roof has a lot more contaminants in the water making it more conductive than snow or pristine rainwater ice.? At one point I had the shingles replaced.? The dipole SWR was way off from what it had been.? It turned out the new building code required metal edging under the shingles at the perimeter of the roof.

This is an essential skill and habit that should be ingrained into every successful contester and DXer. Simply pushing the K3 attenuator button is enough.

You just need to have a serial port or a USB adapter for connecting with a computer. I never bothered to upgrade mine when I upgraded the synthesizers on my K3. Many of us have found the panadapter to be very helpful. The P3 panadapter is a pretty sophisticated device and many of us have found it really helpful particularly in contest situations. It is kind of like moving around the band with your eyes open instead of operating blind.

I thought, seeing the icon come on when I just hit the Notch button, that the Notch filter was active in the cw mode. I didn't realize I had to press and hold the button. Once I held the button, the display for VFO-B changed to the HZ display, and boy that filter works great! Thanks again for all your help. 73 de Bernie, KF0QS Hi Bernie, I think the trick is to press and hold the "NTCH" button to enter the manual notch mode. If you only tap the button, even though the display reads "Manual" and the icon appears, it is not really in the manual notch mode. For example, my CW sidetone pitch is set to 560 Hz. If I tune a carrier to 560, and fully engage the notch mode, I can completely null a carrier when I tune VFO B to 560 Hz. The other clue: If you only tap "NTCH", adjusting VFO B only displays frequency, whereas pushing and holding will cause VFO B knob to display the notch filter frequency. Hope this helps. 73, Jim - WS6X -----Original Message----- From: elecraft-boun... at mailman.qth.net On Behalf Of Bernie and Cheryl Sent: Wednesday, December 16, 2020 1:16 AM To: Elecraft at mailman.qth.net Subject: [Elecraft] K3s Notch Filter Dear Folks: I have a question about use of the Notch filter on my K3s. I am primarily a CW operator. I understand that, in CW mode, the notch filter's operation is manual, and you tune (adjust?) the filter using the VFO B knob (admittedly, I've not tried it in USB or LSB mode, where I understand its operation is automatic, unless you opt out). I have tried using the filter in CW mode and can detect no effect whatsoever while turning the VFO B knob. I even tried it on the AM broadcast band, with the rig in CW mode, and was unable to have any effect on the AM carrier. For what it is worth, the little indicator on the LCD display, with the two arrows, does come on when I press the Notch filter button. What am I doing wrong?

Now I find my P3 a very useful accessory and would not want to be without it for my home station. One example: up here in Alaska at 61 degrees N, often most of the bands are ?dead?. I can go into the shack and quickly scroll through the bands and see if any signals are on the band. Typically if a signal shows up on the P3, it might be workable, but if it does not show up, probably not workable. On bands like 160 meters with little activity, I can immediately see if it is even worth sitting down at the operating desk, or I may decide to watch TV, read, or go out skiing. Occasionally I dig out my microphone and operate SSB. Sometimes on a 75 meter net, I want to talk to another ham, so can see on my display that there is a (relatively) open frequency 13 KHz up, so just ask him to QSY up 13 so the net can continue on ?it?s? frequency. Also I have 2 or 3 antennas on some bands, with the P3 I can quickly see which works best and also that my RX array may be better for RX than my other antennas. Also I can electronically rotate my RX array and quickly see which direction has the best S to S+N ratio, which is not always the setting for max signal. I do not need a big, or colored display. You can set the P3 off to the side and not be distracted except when you need it. I set my P3 up to cover 50 KHz of a band so can see where or if there is any action. Now if I only had a display weighing only a few ounces for my backpacking QRP rigs ! I really enjoy my K3S and have no plans to ?upgrade? personally, even though budget is not an issue. Enjoy your Elecraft rigs, I have 3 of them !

The amp and ATU are in a separate enclosure. I have used it mostly for CW, but lately I have been using it for digital with a MicroHam DXP interface. When operating digital I keep an eye on the transmitter ALC level, where I expect to see 1 bar. I noticed recently that on 20 meters I can't get even 1 bar on the ALC meter, even turning the DXP's TX audio level up a lot. The RF output meter shows very low output power. No similar problem on 80, 40, 30 meters. I plugged in a Heil Proset mic and observed the same behavior -- when I speak into the mic there is plenty of TX audio on 80 and 40 meters (too much in fact, even speaking very softly). On 20 meters I have to yell into the mic to get 1 bar of ALC. This is with the output power set to 50 watts, Mic gain set to "2" (choices are "1", "2" and "3"), compression set to "1", ATU disabled (set to CAL).

This is problematic when trying to run digital modes, where the audio input needs to be adjusted on every band. I wonder if you have lower gain on 20m because you have a transmitter alignment problem ? perhaps one of the 20m tuned circuits needs to be adjusted. Gain seems to fall off on higher bands ? I wonder how well you fare on 15 or 10m. You also don?t say which mic you have on your Heil Proset. It it one with the older crystal HC-4 or HC-5 elements? These have pretty low output. I have two headsets (one BM-10 and one Proset) originally with the HC-4 elements. I had to modify my K2 to get acceptable output. (I changed KSB2 R14 from 1k to 3.9k) The element in the BM-10 died, and I replaced it with an electret mic element. I?ve also switched to another headset with an electret mic that has a lot of output (Yamaha CM500) and had to reverse the modification. > On Dec 18, 2020, at 6:14 PM, Mark Newbold wrote: > > Hi all, > > I acquired a secondhand K2/100 with KAT100 ATU a while back. The amp and ATU are in a separate enclosure. I have used it mostly for CW, but lately I have been using it for digital with a MicroHam DXP interface. When operating digital I keep an eye on the transmitter ALC level, where I expect to see 1 bar.

Check this in the menu and also right near where the power enters the KX2. Full power is only possible With a good ?stiff? power supply. If you use the internal battery pack, the power will drop off, perhaps around what you get, after a little use, but then you can operate for some hours at QRP power levels. If you run the KX2 with a good AC power supply which puts out hopefully at least 13 volts, you should get the full specified power. Even something like a 12 volt gel cell, will soon drop down below 12 volts and may or may not support full power. If you have small wires between an external supply and an in line fuse this could be a slight possibility. Check the above things out first since it is an easy step. If you are measuring the power output with an inline SWR/wattmeter into an antenna without perfect 50 ohm SWR of 1:1 the power reading from it could easily be off by 50 %.

I can't answer your question about the speaker jack, but I assume it is because of the lighting in the photos. You can easily replace the SO-239 jacks with the connector of your choice, but IMHO it will not make any difference. I once changed those connectors to type N because that customer did not trust the UHF connectors. Support of the K3 and K3S will not end just because they are not shipping. I worked Elecraft Support for the Legacy Gear from 2004 until Feb 2019, and every product that Elecraft has produced is supported as long as parts are available. My experience with Elecraft goes back to the start of the company in 1998. The CW decode will work with SubRX on or off. The KIO3 or KIO3A is adequate if you connect to RS-232 ports or a good USB to RS-232 adapter (FTDI chipset). If something happens and it fails, you will have to upgrade to the KIO3B. Similarly, the synthesizers - the old ones are no longer available from Elecraft, and in case of failure, the new synthesizers would have to be used as replacements. If your K3 has the old synthesizers, replacing them would give a big advantage - the K3S already has the upgraded synthesizers. So as long as the parts are available, Elecraft will continue to support their older products. The only products that are no longer supported (for lack of replacement parts) are the K1 4 band board (should the trimmer capacitors fail) or some of the parts for the XV50, XV222, and XV432 transverters - again only for lack of some replacement parts. Even those older units that have parts availability problems may be sent in for service, and will be repaired unless the failure is because of a no longer available part. I expect this practice to continue for many years with the K3 and K3S as well as the Legacy Products. I am quite pleased with my K3 upgraded with the new synthesizers, and it will likely be my last transceiver, although I also have my original Field Test K2 (fully upgraded) and a KX3/PX3/KXPA100 and KX2 for field work. All carry SN 000020 except for the KX2. Both the K3 and the KX3 have been sent through the Elecraft repair facility, while I upgraded my K2/100 myself because it was the same as I was doing for customers. 73, Don W3FPR On 12/17/2020 12:05 AM, Tony KX3H wrote: > Sorry but I just need a little help with this - I'm in the K4 Group 3 > list and know it will be a while before I get the call, so considering > buying a used K3(S) in the mean time.

Meanwhile, my 13 year old K3 (#170) is acting up with random errors and has turned into a repair project. I needed a radio that I could operate remotely. So, I bought an Icom 7300. It is inexpensive and its performance is in the same ball park as most of the direct conversion SDR receivers. I?ll likely sell it when my K4 arrives. The loss in value of the IC-7300 will be the cost of waiting. BTW, the IC-7300 is pretty bare-bones: Single receiver, no APF. A W4ENE Passive CW filter helps improve the CW reception substantially.

Message-ID: <16e5df6d-6a43-40b7-4091-7d73f93de0f8@googlemail.com> Hi. Decided to update the KX3.? (Having also just updated the XG3Util software, and found that device was up-to-date.) Downloaded the current kx3util software (Linux x86 version) from the Elecraft site, and got that "installed" such as it is. Comm's established with the radio via genuine Elecraft lead, firmware duly identified, new (current) versions of MCU and DSP pulled down from Elecraft OK, and programmed into the radio, all OK. As I have had some minor transmit issues in the past, I then backed up it's existing configuration, and proceeded to the Transmit calibration tab. Clicking on "next", nothing, nada, zilch.? No error messages in the underlying terminal screen I launched it from either. Clicked on "Help" and ... "The GtkHTML library required by the HTML Help Viewer is not installed." is shown. When OK is clicked, back to the calibration dialog display. Tried the Help button, nothing, except in the underlying Terminal session:- Could not load libWebKit Could not load libGtkHTML is shown.? ( Hmmm... WebKit, isn't that some proprietary Apple thing? ) Anyway, the only button there that does anything is the "Cancel" button. So, where to next! I have presently mislaid the user manual by-the-way, and I had odd errors attempting to pull a version from Elecraft with FireFox. Any suggestions welcome.? Oh, anyone who tells me to update to Mint 20, will be shot!? That isn't going to happen yet a while. 73.

These KSYN3 ( the original synth} were replaced by the new syth boards when they first appear on the market in 2018. The KSYN3 boards are for sale for both at $210 or $108 each. I will pay for shipping, handling and insurance for the lower 48. I will be using Priority mail for both boards and first class mail for just one. If for Alaska or Hawaii, then I will check to see what has to be done for shipping cost. Final caution: ALL SALES ARE FINAL. Contact me off list: w1ie at jetbroadband.com.

I've been head down, along with the rest of our team and our suppliers, for a good part of this month working to solve problems and get K4s flowing out to you faster. We ran into delays in December due to several items: Our biggest problem has been due to an interruption of deliveries on critical K4 Printed Circuit Board Assemblies (PCBAs) from our primary high-quality assembly subcontractor, who is located near us in Monterey, CA. This was due to both an unexpected surge in demand from their other customers, who were ramping up faster than expected, and on top of our K4 production needs, a significant increase in demand from us for our regular non-K4 product PCBAs (KPA1500, KX3, KX2, etc.) - both from huge Black Friday/Cyber Monday orders and our normal holiday season surge in sales. Due to a miscommunication between us, they delayed several key K4 PCBAs in favor of PCBAs for our other products. When we finally caught the error (after multiple shipments were late or did not arrive) it took several weeks to get everything straightened out. Circuit board assembly lines, parts acquisition, etc. do not stop and start on a dime. This is frustrating to say the least. While we may have received the majority of the K4 PCB assemblies, if any of the other boards needed to complete the K4 100% are delayed, it holds up K4 manufacturing. That's frustrating for us and of course you. We've corrected the issue and we will see more PCBAs arriving late this week or next week. This should get K4 production back on track with regular deliveries to us on a weekly basis. I'm hopeful that January and beyond will be much smoother. We have also just received several needed parts for a small number of production K4s that had all their circuit boards and were already in manufacturing. These K4s will be ready to test soon. If all goes well, they will be out by next week. If there are additional test-related delays, they will ship the following week. Early in December, it took us longer to finish implementing and testing a planned update to the K4's internal Linux OS, which slowed things a bit. Thanks to the hard work from our s/w engineers and our Field Testers, that's completed, and we have updated the automated s/w build process and server along with K4's built-in s/w update process. It's very cool and easy to use. The other news is that due to the larger than expected surge in regular orders, above and beyond orders and backlog for K4's, we have a very large regular product backlog which we are shipping to you as quickly as possible. One last note - Elecraft will be closed for the holidays this Thursday and Friday (12/24-25) and New Years Day on Friday (1/1), with a few employees off extra days for well-deserved rest during that period. We hope everyone has a great holiday!

The 75A power pole connector that feeds the back of the amplifier section just falls out. It hasn't been hit/moved or anything for years. The failure seems to be due to the weight of the DC cable continually pulling down on the connector - the amp section is on my operating desk and the power supply section is directly underneath it on the floor. That cable is pretty heavy stuff, so I'm not really surprised.? So, what's the fix? Has anyone else had this issue?? I can easily replace the power pole connectors at the amp end of the cable (maybe just lose a couple of inches of the cable - not a big deal), but what if the "wear" is in the connector part that's soldered to the PCB inside the amp section? I guess I could take it all apart and replace them if needed....but I'd rather not have to. Any ideas?

The LPAs are somewhat interchangeable, they don't always make full power in some cases. In any case, you MUST run the TX gain cal if you swap modules, so run it now and it should reveal problems.

No special handling?no special considerations... One caveat I will mention is that you will want to avoid using ?parcel post? at the post office, at least to Hawaii. In exchange for being cheaper, its much slower?I have seen packages sent parcel post take 1 to 3 months to show up at their destination in Hawaii. Priority and First Class are reasonable, really. Certainly more reasonable than UPS and FedEx, both of which can get very pricey. Finally, check out the Flat Rate boxes available at the PO?sometimes that can be a REAL bargain if the item is on the heavier side. 73, David - N5DCH > On Dec 22, 2020, at 10:23 AM, Don Wilhelm wrote: > > Jerry, > > I too can state that 1st class or priority mail to Alaska and Hawaii is the same as the lower 48.

Message-ID: When we lived and worked in Grenada we found out the following: All parcels USPS, FedEx, UPS, DHL went through PR. UPS had theft problems, where the tracking would show items disappearing. Especially high value things such as professional colour laser printers. DHL and USPS were expensive. FedEx were ultra reliable and delivered to the Abbott plant on time. The REAL trick was NOT to use their Express 1 day or 2 day levels. We used the 7 day delivery plan. In reality, the cost was less than USPS and the rest by a mile! The 7 day items arrived as quickly as next day, every time on the same plane(s). On talking to others on other islands (8P, J6, 9Y etc.) it was exactly the same. Lots of sailors found it easy to order parts (even heavy things like anchors) and ship them direct by FedEx Economy and get them next day. I sent a BIG box of CAT5 cable (5000'), routers and UPSes all for crazy pricing ($50 vs. $300). So, check it out. You may be surprised. 73, Paul G4BKI, VP9KF, J37KF, etc. From n6kr at elecraft.com Tue Dec 22 14:36:02 2020 From: n6kr at elecraft.com (Wayne Burdick) Date: Tue, 22 Dec 2020 11:36:02 -0800 Subject: [Elecraft] K4 Status Update In-Reply-To: <250744016.3338553.1608628483198@mail.yahoo.com> References: <250744016.3338553.1608628483198.ref@mail.yahoo.com> <250744016.3338553.1608628483198@mail.yahoo.com> Message-ID: <7DE87F34-E41D-4BB5-B1EB-7312204D86A5@elecraft.com> Dunfell.

With the proper drive level set on a new band the first dit would display a huge surge over 1900w, then settle down to normal over 2-3 seconds.? This would happen again if the drive from the K3 were readjusted even by 1 watt!? I know several others have had this problem.? Bob said the K3 should never transmit at or have CONFIG:TUN PWR set to 50w.? I didn't realize this before, since that probably caused my problem. The solution is to redo the TX GAIN calibration.? I think that process is too vague in the K3 manual, since I'm a dummy with this stuff.? Here's what I did with the K3 to solve the problem: Set CONFIG:PWR SET to PER BAND Set PWR control to 5w Set CONFIG:TUN PWR to 5w Hold TUNE - saw 5w Repeated all with 50w settings - saw 50w Immediately reset TUN PWR to 25w Immediately reset PWR to 100w Drive power settings for the KPA1500 were retained I also went to the KPA1500 and adjusted WMTR ADJUST on each band to show close to my trusty Bird 43 values.? Again, do NOT transmit at 50w with the K3. 73, Jim W6YA From lists at subich.com Tue Dec 22 15:42:15 2020 From: lists at subich.com (Joe Subich, W4TV) Date: Tue, 22 Dec 2020 15:42:15 -0500 Subject: [Elecraft] FT8 WITH K3 AND STATIONMASTER In-Reply-To: References: Message-ID: > For FT-8 will my audio cables go from the computer to the K3 Yes. > or will the SM handle all that through the USB connection.

The 75 amp PP connectors do slip easily from the amp, as was earlier noted make sure you hear or feel 2 clicks and is solidly attached. 73, Lou W0FK -- Sent from: http://elecraft.365791.n2.nabble.com/ From kb7our at msn.com Wed Dec 23 14:56:25 2020 From: kb7our at msn.com (kb7our) Date: Wed, 23 Dec 2020 12:56:25 -0700 (MST) Subject: [Elecraft] New KPA 500 Questions: Idle HV and Info button Message-ID: <1608753385770-0.post@n2.nabble.com> Newly assembled AMP. Two quick questions - 1) At 120V using green tap, idle HV is ~87V which is just over the recommended 85 but not enough to trigger a fault. This setting provides just over 60V at 500W+. Also keeps the amp hum nice and quiet vs the other 2 louder tap options which do keep idle HV under 85 but < 60V under load. Ok to operate a little out of the upper V range using the green tap? 2) Also, I found no reference in searches or manual for the INFO button. Looks like it's not being used for anything - do I have this correct? Thanks!

So maybe 25 or more per month? 11712 - 11029 = 683 units between Nov 2016 and Sept 4, 2018 (669 days). This assumes 11029 was shipped Nov 4, 2016. So it is possible the 1 per day or a bit more is within the realm of possibility between those dates. So 11029 - 10599 = 430. 430 days before is Sept 1, 2015. Naturally, their production and shipping would be in spurts and would ramp up from early release to full production (minus stoppages and weekends/holidays, etc.). So it just gives you a very rough idea on how many they may have sold. When were the first K3S's shipped? Besides, I imagine you could call Elecraft with your serial number and they could tell you when it first shipped. Regarding shipping to HI/AK/PR: What irks me is how people get free shipping in the upper 48 but almost never do we in Hawaii get offered a discount on the shipping of the difference between the two. We pay full pop. I've pointed it out to some vendors but never get a reply. Discrimination? Lazy? Stupid marketers along with incompetent site POS programmers? Or, likely, our business volume just doesn't merit any consideration (see previous descriptions). Vendors who promote that on their sites would get my business and recommendation. 73, Kimo KH7U (on vacation so I can waste time on things like this) Date: Tue, 22 Dec 2020 19:23:24 -0500 From: Steve Boles To: "kc8wh.mh" Cc: elecraft at mailman.qth.net, cx7tt at 4email.net Subject: Re: [Elecraft] Year vs serial number Message-ID: Content-Type: text/plain; charset="UTF-8" Very interesting...

PA voltage will vary with current and current depends on efficiency which will vary with frequency and quality of antenna match. e.g. TX freq = 1840500 Hz PA voltage = 63.7 V PA current = 10.2 A PA input = 649 W Drv pwr = 027 W RF out = 517 W PA diss = 132 W PA effic = 79% 2) Also, I found no reference in searches or manual for the INFO button. Looks like it's not being used for anything. I press INFO to clear any fault that may have tripped. I initially expected it to display more info on the fault but it doesn't. 73, Andy, k3wyc From ws6x.ars at gmail.com Thu Dec 24 11:37:55 2020 From: ws6x.ars at gmail.com (ws6x.ars at gmail.com) Date: Thu, 24 Dec 2020 11:37:55 -0500 Subject: [Elecraft] FS: Elecraft Accessories Message-ID: <003f01d6da13$23d82550$6b886ff0$@gmail.com> For Sale: MH2 - Elecraft Microphone, like new - $45 shipped to the *US.

(Energizer 2300 mAh stamped "C1 1-14 UJP", so 6 years is right.) I set those aside a year or two ago, as I wasn't operating portable with the internal pack at the time. I also was a bit suspicious of the battery capacity at the time. Recently, I put them back in for some portable play and found out they are in poor shape. How poor? Bad enough to trip the KX3's low voltage detection. The built in metering (V, I) is great, so I used that to measure internal resistance with a dummy load. I had to go to a lower frequency band and/or reduce TX power to avoid sagging to the point of tripping the low voltage detector. 10 MHz and 1 W worked in my case. Idle: 9.9 V 0.175 A TX carrier: 8.5 V 0.579 A --> Rs = 3.5 Ohms or 440 milliOhms per cell Not good. Picked up the same brand same with the same capacity from a local retailer, again. (That's all they had. Stamped "0720CP14", sounds new.) Popped those in. Idle: 9.8 V 0.174 A TX carrier: 9.4 V 0.583 A --> Rs = 0.98 Ohms or 120 milliOhms per cell A few TX cycles and I see: Idle: 9.6 V 0.174 A TX carrier: 9.4 V 0.582 A --> 0.49 Ohms or 61 milliOhms per cell Looks good! The built in metering is so useful. Love the clock, too, for logging during SOTA activations.

So it seems an unnecessary invalid initial answer to a question that did not exist regarding bypass mode. However ; "You may run up to 200 watts through the KPA500 in STBY." was on the money.

It is either Off, On in STBY, or On in OPER. Picky, picky, picky. :) When all of the power amps I'm aware of are in a mode usually called "Standby," meaning that they are powered up and ready to transmit, but are Bypassed. they are Bypassed. They are also Bypassed when turned off. And when tube amps are prevented from transmitting when their filaments are warming up, they are Bypassed. 73, Jim K9YC From g0ruz at g0ruz.com Sat Dec 26 05:19:25 2020 From: g0ruz at g0ruz.com (Conrad PA5Y) Date: Sat, 26 Dec 2020 10:19:25 +0000 Subject: [Elecraft] K3S Birdy on 28MHz Message-ID: Hi all, I just discovered a birdy in a very awkward place on 28.360MHz.

As a result I tried using my XG1 to do the sideband cancellation calibration described in the KXFL3 manual. During the calibration I could significantly reduce the sideband so that it could no longer be heard by ear. But, once I left calibration mode, I could still hear the opposite sideband from the XG1. I did restart the KX3 to save these settings and confirmed that the phase and amplitude settings were saved per filter. Any suggestions?

In-Reply-To: References: Message-ID: Hi. I'm seeing strangeness between the command values used to set the AF Gain, and what is returned when you query it, even using the KX3 utility software (v1.2.12.21) The front panel control range is 0 to 60.? The values returned when querying the radio follow that just fine as you query it while twiddling that knob. But... Sending the command AG060; does not result in maximum AF Gain.? For that, it needs AG100; sent to the radio. If you send AG060; (or AG60;) then the "volume" is about 50% of maximum (by ear.)? Poll the radio with AG; and it returns AG060; But, if you gently turn the AF Gain control counter-clockwise, the front panel volume setting shows AF 59, but the volume (by ear) goes UP.? Turning the control clockwise, will also bring the volume up, but the value stays at 60. If you send AG100; to get maximum volume, and then send (for example) AG070; to reduce it, it does reduce.? But, if you query the radio with AG;? It returns AG060; As before, all of the above is when using the KX3utility, to send and receive commands and parameters between PC and radio. PC's OS is LinuxMint 19.3 64 bit all up-to-date.? Also using a genuine KXUSB cable, FTDI chipset version. My KX3 MCU firmware is Rev 02.95 and DSP firmware is 01.52 MCU or DSP Firmware issues? I Initially found this, when investigating to "adjust" Flrig to work correctly with the KX3, using the radio's native parameter values.? Currently it seems to use K3 remote command values for most things. As anyone who has messed with the remote control of these radios will know, a KX3 is very different in detail, to the K3 in many command parameters. Seasons Greetings etc. 73.

The last time I did it, I used an XG3 and calibrated each filter on each band (there are actually per-band phase/gain settings for each filter). If you used an XG1 did you calibrate on the 40M fundamental, or was there enough 2nd harmonic to calibrate on 20M? I found considerable differences in per-band gain/phase settings. So it wouldn?t be surprising if the null depth is not quite as good on a band you had not specifically calibrated for. And in some cases you could still barely hear the alternate sideband ? but it was very weak in any case. I also found that the automatic null routines didn?t always get to the deepest null. Elecraft says that it?s (60+ dB) good enough, and it likely is from any practical view point. But it was possible in some cases to improve the null slightly by a +/- 1 count manual adjustment of either the phase or gain setting after running the auto-null routine. It varied by band and filter, and manual tweaking didn?t always result in any improvement.

The reason this is effective for many spurs is because they're the product of harmonics of the signal sources, not the fundamentals. For example, you may hear a spur that results from mixing of the 3rd harmonic of the VFO beating against the 9th harmonic of the BFO (any combination is possible). That's the nature of high-level mixers in superhet transceivers. SIG RMV shifts the VFO and BFO by the same amount *at their fundamentals*, but the spurs end up shifted by a multiple of this amount. Using the previous example, a 100 Hz shift at the fundamental might shift the VFO 300 Hz and the BFO 900 Hz. (Often the multiples are much higher -- I've seen them up to 21.) Doing this often moves the spur out of the passband, while having an insignificant effect on the filter center frequency (these are fixed because of the crystal filters). You can create SIG RMV entries separately for both the main and sub receivers on the K3/K3S. 73, Wayne N6KR > On Dec 26, 2020, at 3:44 AM, Conrad PA5Y wrote: > > Thanks to G4ZTR I found "SIG RMV" in the Config Menu.

It does not process the signal in any way, merely acknowledges its presence. It does not have a Bypass mode. In order to Bypass it, I need to move a couple of cables. My KAT500, however, does have a BYPASS mode in which it measures the SWR and makes a decision on whether or not to provide any additional processing, other than routing it to the preferred ANTENNA, based on my indicated preferences. 73.0 Lyn, W0LEN -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: Saturday, December 26, 2020 1:55 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA500 Bypass Power Limit?

Picky, picky, picky. :) When all of the power amps I'm aware of are in a mode usually called "Standby," meaning that they are powered up and ready to transmit, but are Bypassed. they are Bypassed. They are also Bypassed when turned off. And when tube amps are prevented from transmitting when their filaments are warming up, they are Bypassed. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at 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 lyn at lnainc.com From donwilh at embarqmail.com Sat Dec 26 17:14:07 2020 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 26 Dec 2020 17:14:07 -0500 Subject: [Elecraft] S2-3 on K3 With No Antenna?

Message-ID: I?ve been wondering as I contemplate replacing at least two of the push button switches, if there is a more permanent fix. The schematic is available on the Elecraft website. What do you think of installing say a 10K pull-up resistor from the 3 vdc buss to each of the switch outputs. I wonder if that would stabilize the inputs. It seems like the issue is no-current switching making the contact noisy after repeated use. 10 K doesn?t seem like much of a current to help, but that and maybe the presence of a load would reduce the noise to the pic processor.

When I put the knob back on, I found that if I pushed it against the felt, it was too stiff. If I just dropped it on the shaft and then set the screw, it was back to the factory feel. I remembered seeing this post and figured the experience was worth mentioning for the next builder or blunderer. I was surprised at he variance.

The list is configured so that when you REPLY to someone's post, it only puts that person's email address in the TO: line. You have to ADD the Elecraft reflector address to that address line to send it to the list. Most people who send individuals things meant for the Elecraft list do not notice that this is happening, or don't know how to fix it. Perhaps we need to ask Elecraft to change the settings on the list, so replies to a post ON the list is directed TO the list, instead of to the person who initially posted it. Case in point, even though Joe posted this to the list, my reply only has Joe's address on the TO: line. I will have to add the list's address to it. I usually also remove the poster's address, as there's no reason to send it to both addresses. Look at the address headers in anyone's post to the list. The Reply-To: line shows the poster's address. Not the Elecraft list. So, Joe, this is not someone's deliberate attempt to annoy you, nor do they somehow think you work for Elecraft. They don't. It's 95% certain that they didn't intend to reply to only you, that they really wanted to post it to the reflector. But they either didn't know or notice this was how the list was configured, they didn't know how to fix it, or both. So yelling at them isn't necessarily going to fix the problem. Reconfiguring the list so replies go TO the list WILL. I've run enough mailing lists and such over the past decades since such things existed that I've seen this happen countless times. It's a list configuration issue. Not an interpersonal one. -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Mon, Dec 28, 2020 at 9:42 AM Joseph Shuman via Elecraft < elecraft at mailman.qth.net> wrote: > I received an email this morning, to my personal address, from another > operator I do not know, with a complaint about Elecraft.

I've never had that problem. Are you sure you're using the latest release? How it responds does, indeed, vary with how an email reflector is set. For this reflector, if the post is only to the reflector, it gives me the choice of Reflector or Sender. If, as you did, you responded to the Reflector AND to me, I get the choice of Reply, which goes to you, or Reply All, which goes to both you and the Reflector. FWIW, when someone replies to a Reflector of which I'm a member, I consider a second copy to me as spam. 73, Jim K9YC On 12/28/2020 1:30 PM, Alan Bloom wrote: > I'm also using Thunderbird, but when I chose "Reply List" it puts my own > email address in the "To" field instead of the list address.

The message demeaned Elecraft as a company and accused them of illegal acts.

I used the Elecraft Frequency Memory Editor to accomplish this. Now, I can start at 160m, hit the M>V button, then M1, and very quickly have the CW frequency in VFO A and the SSB frequency in VFO B for each band. With a little thought and organization, the Frequency Editor is a handy tool for such things as using a segment for contest frequencies, SOTA, CH, etc. Those Elecraft designers are whitty!

I and from what I understand others have problems with FLRIG. But quite different from your problem, FLRIG continuously sets transmit on my KX3. I suggest you try HAMLIB for rig control. I know it is not as full featured as FLRIG, but appears to be a lot more stable. Yes I know there is a lot of difference in the interface between the KX3 and your K3s. I use a signalink for my audio CODEC and your K3s has it built in. If you are receiving audio then you probably have FLDIGI pointed to the proper sound CODEC. As long as you have selected both for transmit and recieve. Make sure your rig control software in FLDIGI is set up properly to control PTT. I might suggest reviewing NBEMS videos on youtube. They go through in depth detail for setup. I am on my phone, I will later send you the URL for YouTube videos, when I get on my computer. The setup can be a little overwhelming. I use the videos as I go through every setup. Not to say I don't have setup problems, but those videos have solved all my problems. Good Luck and let me know how it works out. 73, Charlie, N2PKW Sent via the Samsung GALAXY S?4, an AT&T 4G LTE smartphone -------- Original message -------- From: wb0m at flashdog.us Date: 12/28/2020 9:04 PM (GMT-06:00) To: elecraft at mailman.qth.net Subject: [EXT]: [Elecraft] K3S - Fldigi - macMini Greetings Everyone & HNY, I am having problems setting up Fldigi with a new macMini & my K3S.
