Re: [Elecraft] Power oscillation problem (KPA500+KAT500)
NOT directly related, and MAY not be related AT ALL but consider clearing the tuning solutions stored on a section of the band where it oscillates and let it RE-tune at a power level JUST below what it was oscillating at Then turn her up and see if it still does it. Likely will, but just wanted to eliminate the tuner/tuners fighting. Ideally, I would clear the memory on the KAT500 and internal ATU altogether, but that's a lot of "work" stored across there, so it's a decision you have to make. Just a wild ass suggestion Do you have an ATU in the transceiver? Do you have it turned off when using the KAT500? Have you tried using the internal ATU with the KAT500 taken OUT of line and run the KPA500 through a well-tuned freq. at 100W or so? If you don't have an internal ATU, is there a resonance frequency where you can run 100W without a tuner inline? If so, do that too. Basically, you need to construct circumstances that isolates or eliminates ONE device at a time. ONCE you pin down what device is having the issue, then you can start figuring out what is causing the issue. Apologize, but I got here late and missed some of the original details. Just trying to help. Be well. Clay E. Autery, Jr. KY5G On 11/21/2023 6:50 AM, Andy Durbin wrote: Thanks to those that replied with suggestions. This morning I ran some additional testing. I found I could induce the oscillation at 70 W KPA500 output power. With KPA500 switched to STBY I could run 100 W from my TS-590S with no anomalies. The only change in the antenna system configuration is that KPA500 is in STBY not OPER. The time for onset of oscillation , and the frequency of oscillation, both depend on the power level. The higher the power the quicker the onset and the higher the frequency. To me that suggests a thermal problem rather than voltage induced breakdown. The only ferrite in the 40 m antenna system is in the KPA500 LPF and the KAT500 tuning inductors. The KAT500 inductor configuration was the same for 100 W STBY and 70 W OPER test. Those two facts would, if taken in isolation, suggest a problem in the KPA500 40 m LPF. However, the LPF seems happy at 500 W with the dummy load. I'm finding it hard to find a failure mode that fits all the test data. 73, Andy, k3wyc __ 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 k...@montac.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] Power oscillation problem (KPA500+KAT500)
Listen to Jim, guys. THE most frustrating thing in troubleshooting is when the "trouble" is in the cheap/low quality parts used in an assembly.| ALWAYS buy the best you can find/afford. Buy the best; buy once. I have a FEW more vendors than Jim, but his point is nonetheless valid and should be added to the HAM Gospel: Thou shalt not use cheap crap in thy signal line. This is ALSO why I have eliminated ALL UHF connectors from my station. GOOD ones work fine. Not as well as N and others, but good enough. Problem is that too many of the connectors/adapters with UHF on one end are made like crap or have a fatal flaw in them somewhere just a matter of a short/inconvenient time to failure. Be well!

After getting back on the air in 2003 after 20+ years off, I made the mistake of restocking my parts stash with junk adapters from a Chicago flea market. Over the next five years, I traced a half dozen failures to them as a cause. My definition of a junk connector is one that isn't stamped "Belden," or with a MIL part number, or one of the types made for hard line. Perhaps a ferrite choke that is poorly designed, under-rated for the specific use, or used with a badly imbalanced antenna has failed. They do that. :) And, of course, loose connectors. 73, Jim K9YC __ 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 k...@montac.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] TS-890 vs K4D performance?
Almost never, unless it is a new product that was not available at the time of original purchase. I do my research, analysis, comparison shopping, etc. /before/ I buy. Saves a lot of mistakes and regrets. For instance, I spent about 6 months researching my purchase of an ALL BANDS transceiver in 2016. I chose the Elecraft K3s because overall, it was the best made, performing, supported transceiver line on the planet. I arrived at that position after a great deal of research, demos, etc, etc. THEN, I spent hours studying the assembly and ops manuals. Etc, etc, et al. ad nauseum. I am very deliberate in my decision-making. Be well! 73, Clay E. Autery, Jr. KY5G On 10/23/2023 2:56 PM, Dr. William J.

Re: [Elecraft] Astron RS-35M Hum
If I had that issue on either my 35 or 50, I'd do similar, but I would use the Sorbathane purpose built isolators of the correct dimensions as per the engineering doc. I started out making my own isolators with raw Sorbathane sheet stock, It's phenomenal when you mmatch the right material to the application, and get the design right. I won't use anything else transformers, HDD, etc... 73, Clay E. Autery, Jr. KY5G On 9/29/2023 4:11 PM, Steve Lawrence via Elecraft wrote: Astron RS-35M Hum (and probably other Astrons). I've found some posts in the archives related to this topic so perhaps a bit OT but hopefully of general interest. My Astron RS35M developed a hum that increased with increased load. Otherwise working OK but became annoyingly loud. My solution was to insert a round rubber pad at each of the four mounting screws between the chassis and the transformer. 3/4" OD x 1/4" ID x 1/8 inch thick. https://www.amazon.com/dp/B0BJPF9QMZ The hum now is very low. Nothing that would otherwise stand out if I weren't listening for it. And it does not change with load or increased load. So the problem seems to be mechanical coupling between the transformer and the chassis with the hum amplified when the cover is on the PS. Likely varies with any given batch of transformers. My much older RS-35M exhibits no hum at all even under load. 73 - Steve WB6RSE __ 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 k...@montac.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

Autery, Jr. KY5G On 9/14/2023 8:52 PM, Kenneth Christiansen wrote: I managed to lose the EMAIL from the ham that wanted to sell his K3S and get a KX3 setup for his motor home. I have been using Elecraft rigs for camping for the last 23 years and sure do like them. I have a 100 w K3S with built in tuner, cw filters, the upgraded low noise etc. I have a K4 at home with the KAT500 and KPA500. My camper is a 16 ft fiberglass SCAMP trailer. I used a KX3 and 100 watt amp for camping for many years. When I got the K4 I considered selling the K3S but instead started using it in my camper. It is so much easier to set up then the KX3 and works better for me than the KX3. I run the K3S and P3 direct off the camper battery and have a 100 watt solar panel for charging. I use a 32 ft vertical mounted on the hitch of my trailer and a 5 to 1 UNUN that operates against the chassis of the trailer on 40 thru 10 meters. I also have a loading coil for 80 and 160 using this same vertical. I find it works so well and is easier to set up and take down than my old KX3 setup. I have talked 300 miles to our 160 meter net several times on Sunday mornings and run form 5 to 50 watts on the other bands for CW. The camp spots are often quiet and I fIind I can work more stations from the camper than I can at home because of the lower RF background noise. To make a long story short I recommend using the K3S in a camper if it is already bought and paid for as you will spend more money setting up another radio in your motor home and it will be less handy to set up and take down and there is no other radio that will work as well in the camper. 73 Ken W0CZ I am 81 years old and still enjoying camping __ 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 k...@montac.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] Broke my K2 :(
You can radically mitigate the issue by using a secondary container for that which you'll use in a week or so, and only open the quart/gallon to dispense to working container. I have dry argon in my shack to purge gas space in any container that is hygroscopic or oxidizes in presence of atmosphere. I use 99.9 for cleaning all boards (flush after "scrub").Where allowed, I follow up with RODI water flush and forced air drying.

Re: [Elecraft] Long messages
Having spent the last 25 years administering, owning, running, etc, etc, ad nauseum both forums (from uBBS 1.0, vBBS, et al), and supporting clients with forums, email reflectors, et al. I have to disagree with you. As much as I 1) LOVE forums, and 2) loathe every additional email I don't want/need, for amateur radio related subjects, like Elecraft (I'm in this one and 4 other related on two platforms), I do not think a forum is the way to go. I'm busy, and I don't even GO to most of the forums I spent years on anymore because well, I am busy. The "push" nature of a reflector allows me to review quickly and stay right up to date on all the subject areas I am interested in. Now, that is NOT to say the "reflector" idea cannot be improved upon. I PREFER Groups.io, which is kind of a hybrid of sorts. If you want, it's JUST a reflector. BUT, it ALSO provides a searchable database, and a LOT of other tools for use when you need to research historical threads and posts. Now, I know lots of folks resist change and Groups.io is a change. But it works "better" for a wider range of folks, and IMO is much easier to administer. Finally, IF we are not to move to Groups.io, then I would like to see us return to the basic "rules" we USED to observe before 1) Only quote what is absolutely necessary to keep thread continuity. 2) Strip away everything from the "" and down. 3) Observing the quiet death of threads when they drift and/or sufficiently beat the horse to death. In the past, Eric was the arbiter of the "rules". That is a TERRIBLE use of his time. Perhaps if we could hammer out some rules that Wayne and Eric would "sign-off" upon, and then find a couple of Reflector moderators from among the more experienced, level-headed, and thick-skinned, et al. of us to fulfill the lion's share of the admin duties (with Eric and Wayne ONLY managing by exception), we MIGHT just streamline the reflector traffic a bit. That's my 2/100ths of a fiat currency "dollar".

For example the P3 cannot compare with the display on the K4(D). Throw in performance and it’s even better. Enjoy the hobby whatever you choose to get. Fun is the name of the game. 73, Gary W2CS On Oct 3, 2020, at 12:09 AM, Dave wrote: I was disappointed to see the pricing for the K4. I thought the base K4 would be in or around $3500 to $3700 and perhaps $500 or so to go to the K4D. As it turns out, another $900 for the K4D. These prices do not include the ATU ($400) or even a hand-held Mic. The total for the K4D that I was thinking of purchasing would have been almost $5470. (+shipping ??) it’s out of my price range. It will be interesting to see what the K4HD goes for. I’m glad that I had my $1500 deposit refunded several months ago. I have to wonder if one will really be able to tell the difference between any K4 and the FTDX101D which can be purchased for under $3000 and includes the ATU and a Mic I hope you folks enjoy the K4 as I’m sure it will be a great radio. I will continue to use my K3s as the price for that fine radio is dropping like crazy and has allowed me to pick up a second one for a surprisingly low price. 73, Dave N8AG __ 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 k...@montac.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] K3 going expeditionary
Yup When I did my alternator and battery upgrade (including a complete replacement of the power/ground cables with much heavier cable), for my stereo install, I discovered that very thing even in a TRUCK with a frame. I mapped out and installed massive ground continuity cables from every metal body part to the frame, and finished up by MEASURING the resistance from point to point all over the body, bed, cab, frame, and engine to insure that the entire ground plane was continuous and super low resistance. Maybe overkill, but it works great, and it gives me comfort to know that vibration dampening and oxidation aren't compromising the counterpoise. Side bonus, was that the 12VDC ground plane was so good afterwards, that I have been able to take out a lot of the home run grounds from a bunch of lights, et al... ofsetting weight gain by some bit. 73, __ Clay Autery, KY5G (318) 518-1389 On 08/24/20 17:40, Jim Brown wrote: Yes, and this should definitely be twisted pair, contrary to what's on a highly regarded mobile site.

Re: [Elecraft] K3 going expeditionary
IF it were me, I would run two NEW, 10GA or better high strand count wires (twisted by hand or drill) from the battery to the cabin with appropriate fuses in BOTH POS and NEG lines, and the Anderson PP connector on the end. Ideally, I would also put a SPST switch in the POS (my pref), or a DPST switch across both leads so that I could turn the power off there for connection purposes (optional). This gives you the ability to 1) power the K3 with Key off, engine off if desired, and 2) gives you a big, shortest run dedicated to the radio. Additionally, it gives you a twisted pair, AND the ability to put chokes wherever you might need them to quiet down the power source from possible noise from the vehicle. 73, __ Clay Autery, KY5G (318) 518-1389 On 08/23/20 13:32, Ed K1EP wrote: You could do that.

Re: [Elecraft] FIXED--was NOT the feedline

Pull out a new one to slit the cover and then wrap in a paper towel and dispose of properly. 99% of the time if I "slip" and cut something I don't want to cut is because the blade wasn't sharp enough for the job AKA: applying too much force trying to push a dull edge through a material. These days, I also carry an OLFA H-1 heavy duty retractable razor knife with big thick snappable section blades. I use this in the construction/renovation stuff where I want a handle for the blade.

I was fortunate that the problem was not in the KPA-1500 as I'd originally feared. Much troubleshooting within the past few days. Originally the amp was "iffy" on the old M-squared 6m5, and problematic (faulting) during damp or wet weather. This prompted the replacement of both the antenna and feedline. The hard faults were still occurring, until it was suggested the Ten-Tec 238 tuner that I was using exclusively for the built-in antenna switch was now the issue. I took this out of line today, and lowered the tower to fine-tune the LFA's feed point and now everything is humming along just nicely. The KPA-1500 is happy at 1.5 kW and showing an SWR of 1.2 in dry conditions. I will keep my fingers crossed that the wet weather expected in the next day or so won't bother it all that much. The final step was to move the 6m feedline from the secondary inlet box to the main antenna switch on the big tower. The downside here is I now have an additional 70 feet of BuryFlex in the line, so I'm guessing a total of about 1.5 to 1.7dB of feedline loss.

Re: [Elecraft] OT: The Great KPA Fan Mystery
With a little searching online, you can find ultra-fine dust screens that do not reduce volume too much that are also very thin, and can be temp mounted on the intake vents without radically injuring the aesthetics. IF you care less about aesthetics and more about performance, I can point you in the right direction to constructing an intake filter assembly from OTS parts that will trap 90%+ of the pairborne particulates with less than 3% volume and air velocity reduction. Better than that IF you are willing to pay the prices...

Actually, I have had MUCH more success in isolating the transformer mechanically from the chassis with the aforementioned Sorbathane. https://www.sorbothane.com/Data/Sites/31/pdfs/product-guides/Sorbothane-SPG.pdf < catalog of standard products. I use isolation studs they have metal fasteners to attach to chassis and interior components (transformer primarily), but there is a mechanical decoupling via the Sorbothane material. Alternatively, you could use a sheet of Sorbothane underneath the xformer foorprint and a sheet between the xformer hold down clamp and the xformer body. The principle is 1) Isolate the xformer from the metal chassis... 2) Include enough material mass at the right durometer to convert the vibrations (and audible accompaniment) into heat, et al. Used to use small isolation studs to mount the 10k RPM Barracuda drives in 10-drive arrays in large CalPC steel towers Made them whisper quiet AND protected the drives from shock as well. 73, __ Clay Autery, KY5G (318) 518-1389 On 04/24/20 15:07, Nate Bargmann wrote: * On 2020 24 Apr 11:50 -0500, inventor61 . wrote: If someone has a better idea than mine for making these, I am all ears.

While few of us have 3-phase power in our homes, the systems out on the street ARE 3-phase. These harmonics are present because a very large fraction of the loads on the power system are some form of rectifier-capacitor-input power supply; most of the AC load current flows at the positive and negative peaks of the 60 Hz sine wave to recharge the filter cap. This causes the current waveform to be a series of positive and negative pulses, and the IR drop causes the top of the voltage waveform to be rounded off. And we know that any distorted signal is composed of harmonics. In an ideally balanced three-phase system with only sine-wave loads, the neutral current goes to zero. But when harmonics are present (the distortion), harmonics whose number is divisible by 3 ADD in the neutral rather than cancel. They also add in the ground! Buzz is generated by leakage current in the power system; it can couple into our equipment by a couple of mechanisms. It can be eliminated by 1) proper bonding within our home and station; and 2) getting power for all station equipment, including computers and other accessories, from the same AC outlet, or from outlets whose green wires are bonded together.

This was the response: The Vp is not measured at any frequency and is independent of frequency. The only variable in play is the dielectric constant. The Vp represents the speed at which a signal transmits along the cable as a % of the speed of air. Air/vacuum will be the fasted medium to use to transmit an RF signal. The thing is, air is usually not practical since there is nothing to support the center conductor, can be easily crushed and is susceptible to the ingress of moisture. We use foamed dielectrics and expanded tapes to get as close to air as possible. Vp will vary based on the specific dielectric used. The vast majority of our cables range in velocity of propagation from 76% to 86%. For a given cable, the Vp will likely not vary more that +/- 1% over it’s length but as I mentioned earlier, it would be best to use +/-2% for planning purposes.

For this reason, matching sections and stubs must be measured at or near the operating frequency with an analyzer or as a stub placed in line with a generator and receiver. They should be cut long, then trimmed so that the null in that generator/receiver circuit is heard, or the analzyer reads a short or open. How much is this variation?

The vast majority of transceiver users have no concerns about the performance of their transceiver under these conditions. We're discussing the most demanding situations affecting transceiver performance: weak -- often distorted -- SSB signals surrounded by much stronger adjacent channel QRM. For much of the time on 20 and especially 40 meters the adjacent much stronger signals overlap well into the receiver bandwidth. Typical spacing between SSB signals is only 1.5 kHz, if you're lucky its 2.0 kHz and only rarely 2.5 kHz or more. This situation is rather unimportant for the casual contester, but its a game changer at the upper levels of serious SSB contest competition. For transmitted SSB signals we're concerned about situations where our transmitted signal is relatively weak and surrounded by much stronger adjacent channel QRM.

Several of the top contesters are sponsored by some of the radio companies. The winner in the 2014 WRTC was sponsored by Icom as were many others. The same was true in 2018. Of course, they get the best radios, delivered at the competition. Thus the radio choice tends to be biased by the fact that the contesters may not be paying for their radios, or having to hand-carry them to the competition. As for the winners, we have seen many times that the contesters who are most familiar with propagation in the area where the competition is held will win. This was true in Massachusetts, Germany, and will undoubtedly be true in Italy. The top guys travel to the areas to get a feel for propagation, but having experience there for a long time makes a huge difference. In WRTC, it isn’t so much the radio, but rather the experience in the zone that matter the most. Radios, logging software, antennas, etc are pretty much even.

Re: [Elecraft] K4 Update: Transmit Features -- Emphasis on SSB
Yer killin' me Wayne I may have to come out of semi-retirement and take on some extra clients so I can grab a K4 I am absolutely enthralled with the idea of operating on one. The perfect merging of my two (non-XYL) loves now radio and all things IT. May everyone connected to my Elecraft extended gamily be well; be safe; and be Blessed beyond their capacity to contain it. 73 all, __ Clay Autery, KY5G (318) 518-1389 On 03/29/20 13:37, Wayne Burdick wrote: As Eric alluded to, the entire Elecraft design team is safely working from home. We're busy adding new capabilities to the K4 and testing it in real-world conditions. (If it weren't for the lock-down, I and other early users would still be inviting operators over to try it. Previous demonstrations have led to amazement over the sound of the receive audio quality, among other reactions.) With its new, faster DSP, versatile architecture, large display, and essentially unlimited code space, the K4 can offer features that go far beyond what we've been able to offer before. Here's a sampling of what this will mean for SSB users: *** Optimal audio The K4's RX and TX passband in SSB modes can be configured to be flat from below 50 Hz to over 4 kHz, with none of the drawbacks of crystal filters (delay, ripple, passband edge effects). Easy to use graphic TX/RX EQ and other bandwidth controls allow the operator to tailor the response per-mode and for different microphones. The overall effect is full, rich audio in both transmit and receive -- the latter in full stereo. Wider transmit and receive bandwidths can also be configured for digital audio modes, ESSB, and AM, at the operator's discretion. *** Exceptional ALC performance The K4 uses a new ALC system designed to completely eliminate power overshoot and varying loop dynamics. This makes it both easier to adjust and more compatible with external amplifiers. *** Multi-parameter transmit metering In voice modes, the K4 provides clear bar graph displays of all four transmit parameters simultaneously: power output, SWR, ALC, and compression (processing level). Real-time numeric readouts of power, SWR, supply voltage/current, and PA temperature are also available. *** Foolproof split transmit indication You'll never lose track of whether you're in SPLIT mode with the K4: all four transmit bar graphs are grouped either on the left (non-split, i.e. VFO A = TX) or right (split, VFO B = TX). TX icons are also clear and unambiguous. The K4 also allows full cross-band/cross-mode operation in both split and non-split. *** Versatile audio I/O There are mic and headphone jacks on both the front and rear panels. Some operators prefer to use the rear panel connections to avoid cluttering the operating position. Audio for both voice and data modes can be either analog (LINE in/out) or digital (via USB or Ethernet). *** Large DVR memory The digital voice recorder draws on the K4's large pool of flash memory, allowing virtually unlimited expansion for both transmit and receive purposes. There are also new, easy to use playback controls. *** Redesigned PA stages All transmit stages have been upgraded, with improved biasing, parametric monitoring, and T/R sequencing. Hardware is also in place to support closed-loop amplifier IMD optimization, both internally and externally. *** Support for future operating modes With DSP and MCU horsepower to burn, we'll be able to add new voice and data modes in the future (and even new bands). The K4 is designed from the ground up for extensibility in both hardware and software. 73, Wayne N6KR __ 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

It's certainly simple on the XG3 side; the possibly hard part is on your receiver's side. Beware that the XG3 output is a square wave. I am 99% sure that this means the stated power of e.g. -73 dBm is the power of the desired frequency, and the power of the third harmonic is not included in that. Certainly that is what you'd want for receiver testing as a ham receiver should be expected to not respond to the third (fifth, etc.) harmonic. If anyone has measured an XG3's output at various bands and power levels on real test equipment, seeing that data would be nice. The manual says +/- 1 dB typical for most ranges, and doesn't give absolute limits. Still, even about 1 dB is amazingly good for such an inexpensive device. Unless you want to buy proper lab gear with controllable output for vastly more money, the XG3 seems like the best thing out there.

Re: [Elecraft] K-POD working intermitterly
MY bet is a bad KPOD cable As I remember it, it is a straight through cable with 6P6C, RJ12 connectors on both ends. You could make one if you have CAT-5e cable, 6P6C connectors, and a crimp tool. You simply use 3 of the 4-pairs... Cut 4th pair back to jacket (brown has the loosest twist rate, I'd pick that one). And whatever pair you use for Pins 1/2, simply cut the wire that WOULD be on Pin 1 back to the jacket at the radio at least, and I would cut it back on both ends to "be sure" AND not have a "stub" sticking out in space. Crimp them, preferably with connector boot on the KPOD end. IF you have your radio elevated on the from side, there is room for a boot on the radio end as well. If you have the radio sitting flat, there MAY not be room for a boot 6P6C/RJ12 connector boots may be hard to find. In the case that you DON'T use boots, it is IMPORTANT to make SURE that the jacket gets crimped under the connector's strain relief bar on crimp to keep the conductors from separating due to work hardening of the copper when moving the cable. AND, as always for PATCH CABLES, use stranded cable and connectors spec'd for stranded cable to be safe. You CAN use solid cable or solid wire connectors, but the durability will be greatly reduced. Hope this helps... 73, ______ Clay Autery, KY5G (318) 518-1389 On 01/13/20 16:00, John Altman wrote: My K-Pod has stopped working ... it works (macros are functional) for a few minutes after K3S turned on and then power light is out and button functions do not work!

(0.1 Ohms or so between Pin #2 and enclosure; Open from Pin#2 to Pin #3) Pin #3 appears to be the unfiltered (+) as it leads to a rather large trace on the bottom of the board leading from the connector to the interior of the board. So the power wire from P95/Pin #1 goes eother to Pin #1 or Pin #3 on the 2 meter module 12V IN. The picture in the manual APPEARS to be Pin #3 and it follows, as the connector has Pin #1 marked and Pin #1 is traditionally on the left side of a PC Board header.

Pedro, EA4KD -Mensaje original- De: Don Wilhelm [mailto:donw...@embarqmail.com] Enviado el: domingo, 12 de enero de 2020 1:24 Para: Pedro, EA4KD; Elecraft@mailman.qth.net Asunto: Re: [Elecraft] K3 Band Data Pedro and all, The first K3 had band data outputs that were driven by open drain FETs. That means that the receiving unit had to provide the pullup voltage to operate properly. Since almost no one in the amateur community understood the benefits of using open drain or open collector devices to drive the attached device (which would provide the pullup voltage), that was changed so the K3 provided the pullup voltages early in the life of the K3. If your K3 does not provide voltage on the band data lines, then you can add the resistors to +5 volts if you install the REMIOUPGD resistors to the band data lines. This upgrade kit is no longer available from Elecraft, but the instructions can be found in the archives. If you are also wanting to upgrade your K3 with the USB interface, you can install the KIO3BUKT3 which replaces the REMIOPGT kit and provides pullup resistors on the band data lines. 73, Don W3FPR On 1/11/2020 6:53 PM, Pedro, EA4KD wrote: I am the owner of an old K3 (Nov 2007 # 188) and now I need to use Band Data outputs. As they did not work I have been looking for the problem and found that a long time ago there was a board that sold Elecraft to solve the problem (REMIOUPGD) for K3 before December 2008, but that is no longer available. Someone has available a board of these or information to be able to make this modification and use the Band Data?. __ 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 k...@montac.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] K3s throwing a "HIGH CURR" error after installing K144XV and Reference Phase Lock Option
Update... 1) Strictly speaking, removing the RefLock option board and associated SINGLE TMP cable did not "fix" anything... Still have the "HIGH CUR" error. 2) Incidentally, IF you fire the K3s up on ANY other band (after disco and reconnecting power to clear error) WITH the KXUSB cable connected to the computer AND the K144XV "RS-232" port, and THEN switch from any other band TO 2 meters, the status light flashes once as expected (ready for firmware). BUT, the K144XV Utility will NOT connect to the K144XV. Then, of course, if you shut the K3s down while on 2M band and remove the KXUSB cable from its port, then power back up a) Powers up, status light flashes once or twice as expected. b) the K3s shows ANT3 briefly, and then starts trying to display the power-on banner, but is interrupted repeatedly by the HIGH CUR error which remains after the banner scroll completes. c) You have to power down, and disco/reconnect the power to reset. I pulled the left side of the case off ans inspected the IF IN and IF out cables to verify that they are connected correctly AND still fully plugged, and had NOT been pinched off. I think I will try again, with the ANT 3 cable disconnected to remove the BNC cable assembly as a possible cause I'm reaching here now. _*Question:*_ Is there any chance that having the "grip" portion of ANY of the TMP connectors making contact with the K144XV enclosure a "problem"? The ANT3 TNP board connector is set at a slightly OFF angle, and the TMP outer (coax shiield) might be touching the enclosure. Just trying t figure out what is "wrong", and if it anything I have control over... 73, __ Clay Autery, KY5G (318) 518-1389 On 01/11/20 22:01, Clay Autery wrote: Just what the title says I installed a new K144XV and Reference Oscillator Phase Lock Option tonight.

[Elecraft] OT: Speaker Wire Recommendations?
OK... so I am knee deep in assembling and installing a subRX, et al., but got reminded by the XYL that I STILL have not addressed the signal bleed into the audio system via the long runs of parallel conductor speaker wires in the HT setup. In order to maintain a high "SAF" (Spouse Acceptance Factor), I need to deal with this issue WHILE I am in the attic re-configuring the network and routing various shack related wiring. I cannot imagine a stellar group of operators as are gathered here have not had to deal with this before. I am hoping that replacing the speaker wire with either simple twisted pair (or shielded, twisted pair, w/shield properly terminated) will mitigate the hits the HT system is taking. *Q: Do any of y'all have recommendations for a particular wire stock for use in this application?* Small system... only about 50W per channel on the 5 main speakers, so they don't have to be monster-sized conductors. I considered using CAT-5(+) wire and bonding all 4 pair to a single loop, but I don't think a single run would be enough copper (?), and I don't want to make multiple runs per driver. *Any ideas?* 73, -- __ Clay Autery, KY5G (318) 518-1389 __ 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
