I currently have a Alinco DM-330MV which supplies my needs. However, after looking internally and studying the schematics, there is no way to isolate circuit return (negative) from the chassis case ground. Unless I had some insulated, plastic grommet type washers that would hold/isolate the 6 mounting screw heads above (and the threads thru the PCB holes) the circuit return PCB Trace that physically & electrically attach the PCB to the chassis. There is an internal jumper connecting the DC Neg connector to the chassis but without isolating the circuit board return traces from the chassis I'm spinning my wheels. If I read Jim's comments right I just do his slide steps 1 & 2 and accept the chassis ground on the DC negative connector? Thanks for any experienced advice.

I decided the most likely spot for the problem to exist was in the T/R switching circuit in the KPA3A. Schematic on pg. 46 of https://ftp.elecraft.com/K3S/Manuals%20Downloads/E740323%20K3s%20Schematic%20Files.pdf. I removed the KPA3A to take some pictures and figure out how to probe some points of interest, then re-installed it, and took following measurements: Drain of Q4 - 0.25V during RX, 122V during TX Drain of Q6 - 13.7V during RX, 0.24V during TX ... so far seems reasonable ... Measured both sides of L3 and saw 7.42V during RX. Also seems reasonable. Then measured both sides of L1 and saw that it appeared to be floating... hmmmm. L1 and L3 should basically see identical voltages during RX. L1 should not be floating. This means that there's no DC voltage being applied to D2 or D5 anode. That would mean no connection from antenna input to either PA output or RX path. Fits the problem description. I took the KPA3A back out again and did some continuity checking. Shortly I was able to discover that one of the ends of R5 (facing L1) had a failed solder joint to the PCB. When I touched it with the probe, the bad end actually came completely free and lifted up off of the PCB. After starting at it for another minute, I realized that there is a mismatch between the component package size and the footprint on the PCB. The pad spacing on the PCB is too narrow, and even when perfectly centered, there is almost no overlap of the package pins on the resistor and the solder pads that it is supposed to attach to. This is also true of R6 and R12 (though they seem to be connected, at least for now - though notably R12 has a green wire attached to one end). This seems like an assembly defect. Doesn't seem very surprising that with a poor mechanical connection that the solder joint would not hang on. Maybe it can (or already has been in a later run?) be corrected by selecting a resistor that has a package that matches the PCB footprint? Seems likely to me that more KPA3As out there would fail similarly. I noted by contrast that R18 uses the same package as the R5, R6 and R12 components, but appears to have a PCB footprint that correctly aligns with the component. Anyhow, I removed R5 and soldered it back on (turning it at a slight angle, and borrowing the nearby pad of C17 to ensure it had a good solder connection). Now all seems to be well again. Hear lots of signals on RX w/ amp inline an make power out on TX. Hooray! Here are a few pix of the adventure.

My 6m converted Harris ch.2 TV linear is set up this way (amp has openings in the chassis to circuits on input side as well as the final transistors). My W6PQL 1296 LDMOS 600w amp is cooled in the same fashion. Only departure is my W6PQL 2m-1500w linear that has four 2-inch square fans blowing cool air into the heat sink. But I augmented air flow by adding a 4-inch exhaust fan on enclosure top cover. The intake fans were separated from the heat sink by a 2-inch gap which bothered me,so added sheet metal fairings to channel air to the heat sink. Seems to work as heat sink temp remains topped out at 39c running 1400w with JT65 (Overtemp trips off 50v supply at 55c). Even my old 2m-8877 with blower had a 7-inch radial exhaust fan to reduce back pressure on the blower. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From valosin at midtel.net Fri May 1 08:37:24 2020 From: valosin at midtel.net (Tom & Barb Valosin) Date: Fri, 1 May 2020 08:37:24 -0400 Subject: [Elecraft] Dave Popkin Message-ID: For Ted and others, do you remember Dave callsign?

I?m overwhelmed with the info available and compliments posted here and other places on the Elecraft equipment. Near as I can remember the last time I worked 75 meter phone was as a net control on the 3961 net in the early 70?s. I am absolutely out of touch with the whole realm of HF ham radio. So fast forward to today while in retirement I would like to work some 40 meter CW and reading various postings on the .www the products from Elecraft kept coming up - especially all the raves on their receivers. I do remember the saying, ?if you can?t hear them, you can?t work them?. So here I am wanting to buy a KXN so I can go out and sit under a tree and do a little ham radio. I?ve read enough to want to get a KX3 so downloaded its user manual. Moving through it I ran across a sentence saying there was a need for a cable to hook to a PC?oops, that sounded like the Elecraft system was only compatible with Bill Gate's stuff and not Steve Job?s - darn. My question now is should I get software to provide a fake Windows platform for Elecraft or get a real PC and use it as a dedicated option with a KX3? If the later what would be the best choice to purchase? Would really appreciate hearing from you or anyone with a creditable opinion/knowledge on this subject. 73, Tommy > > Well, you came to the right place.?

During the same period lots of bikers tried their hand at building bike frames. This required design, fabricating brazing jigs, and the actual torch work. A few became known builders while most just gave it up as too complex and demanding. All, I assume, continued to ride and race. Moral of this story is that one doesn't need to know how to build a bike frame from scratch in order to enjoy biking. Most racers [the 40+ wpm contest folks...?] then and now couldn't tell you very much about bike frames other than "fit, doesn't fit." Same with cars. My father used to say that "back in the old days" you worked on your car all day Saturday in order to take the family on a Sunday ride. Try that with today's cars. So, perhaps the same goes with radio electronics and ham radio builders and circuit designers. Once, you had to build your own to get on the air. However, other than fun, does anyone here want to do a contest on a crystal set? Probably not. The trade off seems to be between simple and limited versus complex and limitless. The info is there for those who have and/or develop a keen interest in electronics. The rest can appreciate the wonder of it all while enjoying the "front panel" of their radios in their daily QSO's. ...IMHO ...robert On 5/1/2020 03:42 AM, Josh Fiden wrote: > The barrier to entry certainly isn?t what it used to be, but that?s probably a good thing.

The Elecraft cable works just as well with a Mac. Unfortunately, much other ham radio software is not. It tends to be Windows only, although there ARE good general purpose logging programs, digital software, and software for most other functions available for macOS. I guess the Windows focus is that a lot of the code is built by guys in their basements that only have Windows machines, and they just don?t spend the time/money to use cross-platform libraries in the process. And it?s the dreaded Path of Least Resistance. I went the route of Parallels/Windows on my Macs rather than buy another chunk of hardware to deal with. The lack of some main-line ham software in macOS versions is generally irritating, I avoid it whenever possible, but it isn?t always. It is what it is. When I?m out portable with my KX3, there?s no computer involved, and I log with paper and pencil.

Make sure you have current (or recent) Firmware. There is a toggle to reduce tx gain on 6m above 8W; set radio on 6m, above 8 watts, config menu TXGN HP, then tap 8. You should see Atn6 toggle on (showing). Then set radio to exactly 50W on your favorite 6m freq (TUN PWR must be nor). Then long press XMIT to send a carrier for several seconds, then unkey, this will reset 6m tx gain cal. You will see the TXGN number change. Also make sure you don't have too much mic gain, comp, or tx EQ. Keith WE6R Elecraft K3 Tech.

What is required is that the tip and ring of your paddle plug are both connected to the tip of the adapter plug. If you have a schematic for the adapter, that may help - but take your ohmmeter and an empty stereo plug along to check continuity. 73, Don W3FPR On 5/1/2020 1:09 PM, B Deuby wrote: > I want to experiment using my UR5CDX CT 755 single paddle keyer as a cootie.

February 1, 1963 I sat for my Extra with the District Engineer himself in the Federal Building, downtown San Francisco. I never did know his name and I cannot read his signature on the certificate on the wall behind me. I was a barely-21 year old Navy Seaman going to the ET 'A' School on Treasure Island. I was taking the test because one of my classmates had bet me he could get his Extra before I could. If remember correctly he told me he had had 12 screwdrivers that night. I doubt it. Who can count after three of them? They gave the exam every Friday at the FCC office. Friday was exam day every week of the 38 week-long school. In order to take it, I would have to get special permission to take the exam the night before and get the the day off next day. I knew I would be lucky if that happened and I wanted to make very sure that I passed if I got the chance. I doubt the navy would have allowed a second attempt. So for six weeks every night I copied code from 10 wpm through 40 wpm from the local code practice station, K6USN. They were the Naval Reserve station on the other end of the island from us. We were the Schools Command Amateur Radio Club, K6NCG. I could turn the RF Gain down on my receiver and it was like having your own code machine. I progressed until I could copy 30wpm solid and get four of five written down (five letter groups!). I was printing, not writing, and no typewriter. When I walked into the FCC office and asked if I could take the Extra code and written test, you would have thought I had come from Mars. They almost literally rolled out a red carpet. In those days, very few ever attempted the Extra. So the engineer in charge ran the code machine. After allowing a few minutes of warm up, he started the test tape. When it finished he stood up and said,"I will give you a few minutes to cross your T's and dot your I's." He was really trying to be nice to me. Well I had copied every character from the opening "VVV" to the ending "AR" in neat, block letters. I said, "I don't think that will be necessary," and handed him my sheet. he looked at it, smiled and said,"You're right." I don't think he even counted to see if I had 100 characters in a row. I completed the written exam in a couple of hours. I'm not sure how many questions were on it, but I remember one was , "Draw a schematic diagram of a plate modulated transmitter." A couple of weeks later I sat for the First Class Engineer License and got it, with Ship Radar Endorsement. My time at ET school on TI is one of many treasured memories. I believe it was the best of the military electronics schools. I loved every minute of it. 73, Dave, K4TO On Fri, May 1, 2020 at 1:43 PM Phil Kane wrote: > On 5/1/2020 10:15 AM, Joe K2UF wrote: > > > I remember the examiner called me to his desk after the cw test.

The built-in battery greatly reduces the need for an outboard UPS, they're easy to take into the field, and all accommodate an outboard monitor. I take my shack computer into the field three times a year for 7QP, CQP, and FD. This isn't a matter of which OS is better, it's simply that much more ham software is written for Windoze. And as NQ5T has noted, most of it can be run on a Mac in a Windows simulation. And SOME ham software is multi-platform. All of Elecraft's own control programs are written for Windoze and Mac, and K1JT's WSJT-X is compiled for Windoze, Mac, and multiple versions of Linux. 73, Jim K9YC From jackbrindle at me.com Fri May 1 16:24:52 2020 From: jackbrindle at me.com (Jack Brindle) Date: Fri, 1 May 2020 13:24:52 -0700 Subject: [Elecraft] Windows Needed In-Reply-To: References: Message-ID: Before this email query gets hijacked too far afield? Macintoshes do a very good job of handling the needs of hams, especially with Elecraft devices. I do _all_ of my computing with Macintoshes, including a lot of product development.

Bill has done an excellent job with this package, but you probably don?t want to sit in the backyard and contest. https://www.k1gq.com/SkookumLogger/ RumLog, from dl2rum is another contesting package for the Mac. It has some very interesting features as well. https://dl2rum.de/rumsoft/RUMLog.html If you wish to play with FT4, FT8 or any of the other weak-signal modes, the WSJT-X suite works quite well on the Macintosh. https://physics.princeton.edu/pulsar/K1JT/wsjtx.html For controlling and updating your Elecraft equipment, Elecraft has a very nice suite of applications that can be used to update, configure and control Elecraft products. You can download these from the Elecraft site in the support area. https://elecraft.com/pages/firmware-software The list goes on and on. There are a few things I use Windows for (running in a VMware Fusion), but that list is very small.

The operating point for forced air cooling of a system should be the point where the fan curve intercepts the system resistance curve. The fan curve comes from the fan vendor. The system resistance is measured on a flow bench in the lab, or you can can use computational fluid dynamics. But the lab work is ideal if you have the real thing or a decent mock up and is < 1 days worth of work). The system resistance is not something you will typically have at hand though unless you are the designer. Probably most amatuer designers never bother. (It isn't very hard to make your own flow bench.) You typically want to arrange the airflow within the system to maximize dT between the hot things in the enclosure and the working fluid as the heat transferred is proportional to dT (q' = h.dT). That's not always possible for a variety of reasons. Things are in the wrong "order." Sometimes certain components need to be kept cooler (e.g. camera sensor suffers from unacceptable noise with Tj > 60C). For a given fan type, flow rate and pressure drop, there is a fan size that is maximally efficient and least noise. A smaller or larger fan cannot be more efficient and hence less noise. I know some are likely to argue about this. I refer you to [Handbook of Acoustical Measurements and Noise Control, by C. Harris, 1991] for details. That said, you can't (without paying a chunk of NRE) order up an arbitrary size fan, so there is a compromise. Adaptive fan control is another matter .... 73 de Ai6KG -ch On Fri, May 1, 2020 at 12:12 AM Edward R Cole wrote: > My comment NOT about Elecraft cooling design, but: > > I am finding a lot of amplifier designs place fans to exhaust heated > air with cool air being drawn into the heat sink by the partial > vacuum created by the fans. > > My 6m converted Harris ch.2 TV linear is set up this way (amp has > openings in the chassis to circuits on input side as well as the > final transistors). > > My W6PQL 1296 LDMOS 600w amp is cooled in the same fashion. > > Only departure is my W6PQL 2m-1500w linear that has four 2-inch > square fans blowing cool air into the heat sink.

But they said I had to have a First Class Radiotelephone to qualify for the job. No worries I said and I went to work studying. But since I'd have to make the long trip to Boston I decided to take all of these tests in one sitting: - third class radiotelephone - second class radiotelephone - first class radiotelephone - third class radiotelegraph - second class radiotelegraph - radar endorsement - Amateur Extra Several months later I was ready and off I went to Boston. The FCC office had a receptionist "gatekeeper" so I requested the seven license examinations I wanted to take (there were no fees in those days). She smiled at me like I was some smart alec kid trying to prank her. She demanded that I be serious, so I repeated my list,.. She excused herself and brought out the FCC Engineer-in-Charge to challenge me. I recited my requests to him. He -- reluctantly -- agreed and he said "well lets start with the Amateur Extra code test." I smiled and off I went to be tested at 20 WPM, with many of the Boston FCC office workers including the receptionist and the Engineer-in-Charge watching over my shoulder. To make a long story short, three hours later I left the office having qualified for all seven licenses. The FCC Engineer-in-Charge shook my hand as I left with a big smile on his face. I started at WJAR-TV immediately after high school graduation and worked there full time during the summers and part time during the rest of the year for nearly four years while studying for my EE at W1KMV (err... the University of Rhode Island). 73 Frank W3LPL ----- Original Message ----- From: "Phil Kane" To: "Elecraft Reflector" Sent: Friday, May 1, 2020 10:23:23 PM Subject: Re: [Elecraft] New Mystery: Copying groups vs plain language text (Rather OT) On 5/1/2020 11:14 AM, Dave Sublette wrote: > February 1, 1963 I sat for my Extra with the District Engineer himself > in the Federal Building, downtown San Francisco.

The reason you can't run the Mac OS on standard Intel PC hard ware is due to Apple's super irritating proprietary ROM etc... hardware signatures... trickery. Apple goes to extreme lengths to ensure that their OS only will run on their hardware to lock you into buying their hardware to use their OS. Folks will hack and get older versions of the Mac OS working over time on non Apple PC hardware, but then a new Mac OS update comes out and it then breaks running their OS on non Mac / Apple hardware (constant cat and mouse game). I'm not saying they should or shouldn't do that, but that's just what they do. So yeah, you can run a Windows OS on your Mac hardware because #1, it's Intel based hardware and Apple finally adopted a standard intel based platform etc...years ago when they finally dumped the IBM Power PC cpu's and their terrible/horrible preemptive OS at the time (amen! it saved Apple!). Jobs brought them back to the modern OS era by going down the Free BSD OS path, virtually saving them from bankruptcy. (not to mention Microsoft investing 100+ million in Apple back then to keep them alive) So yeah, on your Mac / Apple PC hardware, if you can't live without the Mac OS and you are willing to pony up for the price of their hardware, you can still run the later versions of the Mac OS and also run virtual versions of Windows and or boot directly into Windows on your Mac hardware, because Microsoft doesn't lock their OS down to a specific manufactures Intel based PC hardware. So don't thank Apple for running Windows on your Mac / Apple hardware, thank Microsoft for keeping their OS pretty much hardware independent and not forcing you to run their OS on one company's hardware! Those of us that use Windows as their primary OS, do the same thing as you... you can virtualize and run multiple copies of Windows and other operating systems at the same time like Linux etc... we have been doing that for years of course and yes, we can run hacked versions of the Mac OS too if we want to continually fight Apple in their efforts to lock their Free BSD based OS release after release after release (serious irony that they used Free BSD in the beginning and still lock it to their hardware). At the end of the day, it's nice to have options and for there to be multiple competitors to provide us as consumers with better options and lower prices due to that competition. Let's all be glad that there are multiple consumer OS's out there so the companies compete against each other, not to mention the free versions of Linux too. Options are good! It drives competition, innovation and competitive pricing for the masses.

River Valley at the time.)? For the novice, I was printing in block capitals on yellow lined paper, and doing fine until I heard a character I didn't recognize, and panic set in - shortly relieved by the machine stopping - the character was AR or AS (forget which) but wasn't part of the test at all!? I was a Soph. in college at the time, and that is a lousy time to get a license which lasted only a year, so I converted to a Tech when it expired - didn't have to be tested again for code. Some years later, I finally got up to 13 WPM - must have been unremarkable, as I don't really remember it. Then I got tired of trying to remember where all the sub-band edges were, and decided to go for the Extra.? Same room.? They were supposed to administer the code first and the written afterwards, but when he fired up the "Instructograph" (paper tape with dots and dashes punched through it) it wouldn't work. So he gave me the written (which I passed easily) while he worked on the Instructograph.? Never did get it to work, so gave me the code test with a portable machine that wasn't too much better.? I'm not really sure that I was able to copy a full minute of text, but given all the problems (and the fact that he was giving the tests out of order) he took pity on me and passed me.? So I got an Extra instead of the Advanced.? It was a good 20 years before I got really "into" CW, tho. George, W3HBM On 5/1/2020 8:54 PM, Raymond wrote: > [This message came from an external source.

The heat sink is there. The conduction path between the finals and the heat sink is what it is. The fan is selected and the fan speed temperatures are defined. The only speculation is whether the flow direction is optimum. Elecraft says it is. I have over a year's worth of temperature data logged for my KPA500. My logger records, along with many other KPA500 parameters, the finals temperature, heat sink fin temperature, and Z bracket temperature, once per second for every transmission. I doubt anyone has a better set of temperature data for a KPA500. If I decide to reverse the fan, I do have a good baseline data set against which to evaluate the change. However, the real reason for logging the temperatures was to establish a baseline against which to evaluate any mechanical changes made in an attempt to eliminate the annoying thermal clicks. 73, Andy, k3wyc From k2vco.vic at gmail.com Sat May 2 00:45:39 2020 From: k2vco.vic at gmail.com (Victor Rosenthal 4X6GP) Date: Sat, 2 May 2020 07:45:39 +0300 Subject: [Elecraft] Windows Needed In-Reply-To: References: <9CA01039-3EC1-414C-8431-F2638858E733@gmail.com> Message-ID: <098738cb-d055-ab12-5423-8505af49d214@gmail.com> Apple breaks it's OWN hardware when it wants you to buy a new computer.

Message-ID: I've enjoyed reading these. I have a few stories, having taken the novice test in the civil defense room at the local elementary school and the general test at the NYC FCC office in 1966 as a 16 year old. Dave Poppins, Mr. FCC NYC in my mind, was a legend as an omnipotent presence in all things ham radio regulatory, lived in the next town over in NJ where I grew up. My buddies and I wouldn't key down test our home built transmitters for more than 15 seconds for fear he would show up out of nowhere and bust us because we didn't have our novice licenses in hand yet. My best story is taking the Canadian Basic test. Before buying VY2TT from Robby, VY2SS, I did a multi-op with his gang. Robby was a Canadian license examiner, so I arranged to take the Basic at a multi-op. I read the material and took the multiple choice test. Robby came back a few minutes later and said, "You better study some more!" and handed me the answer sheet showing a score in the 30s. I was so embarrassed. Then the gang went through the questions I "missed" and kept agreeing with my answers. After a bunch, Robby realized he had been sent the wrong answer sheet. The best part was Robby had an Advanced test and told me to take it. I told him I hadn't studied for it and I didn't want to be embarrassed again. He convinced me to take it and I passed. Having heard me copy code in contests, he didn't bother with a CW test. 73, Ken, K6LA / VY2TT From pubx1 at af2z.net Sat May 2 06:21:02 2020 From: pubx1 at af2z.net (Drew AF2Z) Date: Sat, 2 May 2020 06:21:02 -0400 Subject: [Elecraft] New Mystery: Copying groups vs plain language text (Rather OT) In-Reply-To: <1155286425.1872.1588294216465@wamui-marley.atl.sa.earthlink.net> References: <1155286425.1872.1588294216465@wamui-marley.atl.sa.earthlink.net> Message-ID: <1cf4bd19-36c5-bd42-747a-616a4006fb5d@af2z.net> Mike, I also failed the code test for the T2 on my first go round. Can't remember if it was the groups or plain text. At the time you had to wait some period, 6 months?, before you could sit for the test again, unless you were granted a waiver. I had recently received my Extra (which I had sat for in preparation for the T2 test). I applied for the waiver, mentioning that fact in my letter to the FCC. The waiver was granted, and I quickly retook the test and passed. As for the T1, I took it as soon as I was eligible and passed on first try. By then I'd had lots of practice passing traffic under "adverse" conditions at sea. My real trial by fire was working A9M in Bahrain as an apprentice while sailing the Indian Ocean. A9M was a high traffic station with a complicated working arrangement. Several of their operators shared a common working frequency; you would be sending traffic to your operator when another operator would break the station they were working; you were expected to know that the break was not for you and to continue sending, otherwise your operator would come on and tell you to keep sending. Plus, A9M had one of the worst CW operators I ever heard-- complete lack of rhythm, unpredictable spacing, and cranky as hell; I guess he was tired of people not being able to copy his lousy fist. It was quite stressful for a new op-- a mistake copying port instructions or cargo message could mean big bux lost for the shipping company. FWIW, I learned the code from an old Army Signal Corps course on 78 rpm phonograph records, featured in a youtube video on my QRZ page. 73, Drew AF2Z On 04/30/20 19:50, Mike Morrow wrote: > Fred, > > The Radiotelegraph Second Class license required send and receive at 20 wpm Plain Language and 16 wpm Code Groups with no errors for one minute during the five minute test. The First Class license had the same written elements (1, 2, 5, 6) as the Second Class license but the Morse test was 25 wpm Plain Language and 20 wpm Code Groups, plus a six-month service requirement at stations open to public correspondence. (That "public correspondence" service requirement kept many operators with decades of commercial Morse service from ever getting a First Class license. However, every maritime Morse station was defined as open to public correspondence even if it was on a freighter and never had any such traffic.) > > The rare Aircraft Radiotelegraph Endorsement to Second or First Class licenses required the same Morse exam as the First Class license. > > IIRC, the FCC required use of hand copy and straight key for Second Class, but allowed typewritter and bug for the First Class tests. > > After I left the US Navy as a submarine officer more than 40 years ago, I decided I'd like to try my hand as a maritime radio officer before that job disappeared. (I was one of the few Navy people that loved going to sea.) I very much found the seemingly slow 16-wpm Code Group test significantly more difficult for test-taking purposes (when one is still developing skills) than Plain Language. As few as five errors in the 400 character test could prevent getting the required 80 consecutive error-free characters. It took me three 400-mile round trips to the Kansas City Field Office, only because of the 16 wom Code Group test. The 20 wpm Plain Language test (given first) was always child's play. I know that with practice and a mill an automatic unthinking response soon develops, but I did not get that far. > > For many years the FCC waived the Amateur Extra Morse exam for an applicant if he had held a commercial radiotelegraph license. In the mid-1990s, the FCC started waiving the Radiotelegraph Second Class Morse exams for an applicant holding an Amateur Extra Class license. That was a very signicicant relaxation of test standards for the commercial Radiotelegraph license, but by then there wasn't much call for the license. > > I never did get into Radio Officer work because a few months after licensing a new but permanent medical condition disqualified me from Safety-of-Life-at-Sea (SOLAS) duties. During Desert Storm/Desert Shield the US began reactivating enough old US-flag merchant vessels that one of the Radio Officer associations solicited license holders for a short paid training program and employment as new Radio Officers. Even 30 years ago there weren't many newcomers interested in starting a obvious dead end career, but 15 years earlier I'd have sent in my application if medically qualified. > > WRT Phil's comments below, it surprises me when hams claim adamantly that their Morse test was code groups. I attribute that to fading memory. Similary, it was recently stated that a Broadcast Endorsement was attained after earning the Radiotelephone First Class license. The Broadcast Endorsement was granted only to Third Class license holders to show that the announcer (with Third Class license) also had knowledge to serve as transmitter attendant (with Broadcast Endorsement) at small broadcast stations.

I have several USB-C to USB 3.0 adapters, including the Apple ones that I use. Plugged into one of these I have a real FTDI USB to Serial adapter which talks nicely with the Mac. For my K3S, I simply plug the USB cable into the K3S?s USB jack and get both serial control and sound for WSJT-X. So yes, it does work very well. Make sure you are using a serial adapter with an DTDI interface, and do not load any drivers for the port. The FTDI drivers are build into macOS.

Praise for the KX2 Message-ID: Recently I decided after almost 19 years in ham radio I would finally do what it takes to become a CW operator. After about 10 days of re-learning the code and also spending a fair amount of time with sending practice using both my dad's old Radio Shack Straight Key (Ameco look alike) and my MFJ-564 using the practice feature on the Elecraft KX2, I made my first CW contact today with Steve WB2WIK in California. Obviously KX2 was designed by people who love CW and the history of the Elecraft radios has been about really good CW rigs. In general I am still really impressed with how wonderful the CW signals sound, I am listening to K7M right now on 20 meters running in the 7QP, using the default 500Hz B/W and it just amazes me how good the signals sound on this tiny little rig. So I am not saying anything that anyone on this reflector doesn't already know but wanted to share my story and spread some praise. Keep it up Elecraft!

After cycling the main power the HV in standby is back to 70 V. But, every time I go to operate mode, the error reoccurs. This is with what I believe was the old style interlock switch (has a shaft attached to the top cover to engage the switch when the top is screwed down). Can?t tell if it is properly engaging. But the behavior is the same when the top cover is totally removed. How picky is this switch. I bought the amp used, and the assembly manual online at elecraft doesn?t cover the old interlock switch.

Knowing that others can run the KPA500 90C, eases my fear of amp final damage.

In the 60's it was true that the Chinese people made very poor wages but not so any more. It was also true that many of the products were marginal. In the years before I retired, my company shipyarded their vessels in China. Their steel work and production was first rate and fast; much faster than in the US. BUT to be fair, the US yards were full of military vessels. Remember also that the cost of living in China is very much lower than here and their living and social structure are much different.

The amplifier is designed to protect itself, and does a very good job of it no matter the condition. It will do a good job of warning you before anything bad happens; make sure bad things don?t happen very much and your amp will have a very happy life. For temperature, it will declare a fault when the measured temperature reaches 90C. Below that the amplifier works very well, adjusting the fan to keep the PAs as cool as possible. Even though a fault is declared at 90C, the cooling system will continue to run (with the amp in STBY) to get the KPA back into its safe zone. By the way, the KPA exhausts air because that was what our analysis and testing showed was the best for this configuration. Plenty of room behind the amp keeps the back pressure down and the air flowing smoothly so the cooling system does its great job. And, I agree. It is interesting to hear how others experience their KPA500s over various conditions. 73!

Now, the story is totally different and you have to be worried about quality control and intellectual rights issues.

Message-ID: "It is interesting to hear how others experience their KPA500s over various conditions." I have over a years's worth of KPA500 data recorded but it takes some effort to run it through the Excel templates to make pretty plots. My KPA500 temperatures are strongly influenced by ambient temperature. Shack temperature is often over 30 deg C in the summer months and it's not at all unusual for my fan to run at level 3 in FT8 QSO. I think I have only reached fan speed 5 twice and that was while running temperature tests not while operating. I terminated those tests at fan speed 5 and didn't wish to push it any higher.

I hooked one up with a BNC-bannana adapter, but it turns out that there seems to be a series resistance of about 250 ohms, which is inconvenient for resistance measurements. I got the same result from several probes. My question is, what's going on here? Schematics of probes I found all showed that in the X1 position they were straight through. -- 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ From jasimmons at pinewooddata.com Mon May 4 09:53:37 2020 From: jasimmons at pinewooddata.com (John Simmons) Date: Mon, 4 May 2020 08:53:37 -0500 Subject: [Elecraft] Upper limits of KPA500?

In-Reply-To: References: Message-ID: <32D33899-D2B5-4ED6-9800-ADF9E4C822D5@gmail.com> ICAS means Intermittent Commercial and Amateur Service. From the RCA Transmitting Tube Manual: Intermittent Commercial and Amateur Service (ICAS) covers aplications in which high tube output is a more important consideration than long tube life. The term "Intermittent Commercial" in this title applies to types of services in which the operating or "on" periods do not exceed 5 minutes each, and are followed by "off" or stand-by periods of the same or greater duration. The term "Amateur Service" covers other applications where operation is of an infrequent or highly intermittent nature, as well as the use of tubes in "amateur" transmitters. ICAS ratings generally are considerably higher than CCS ratings. Although the ability of a tube to produce greater output power is usually accompanied by a reduction in tube life, the equipment designer may decide that a small tube operated at its ICAS ratings meets his requirements better than a larger tube operated within CCS ratings. > On May 4, 2020, at 8:55 AM, John Simmons wrote: > > ?Nowadays manufacturers use 'ICAS'.

I have two K3, but they were bought used. Am I qualified to be on the list? One of them is the one originally reviewed by QST. The concern with KPA-500 temperature and noise is amusing, given that the hardware is so expensive. For amps, I run 4-125As and 4-400As in several configurations, with most of the tubes at least 50 years old. With either a pair of 125s or a single 400, I can run a KW, key down CW, all day. The electric stove element I use for a dummy load gives off a pleasant warmth in winter. The blowers are scrounged from microwave ovens, cost a few minutes of fun destruction. Not much noise. All the other components are legacies dating back to my childhood or collected through swaps or rescues from sheds and garages. If I didn't have something to build, fix, or test I'd quit hamming, since watching for alarm lights on a black box is even less fun than watching reruns of Blue Bloods! I do have one commercial amp, a Loudenboomer (1960?), from before the company was bought by Hallicrafters. 3-400Z tube, seems to be bulletproof. 73, Wilson W4BOH From wunder at wunderwood.org Mon May 4 11:12:51 2020 From: wunder at wunderwood.org (Walter Underwood) Date: Mon, 4 May 2020 08:12:51 -0700 Subject: [Elecraft] Upper limits of KPA500?

From a.durbin at msn.com Mon May 4 12:56:46 2020 From: a.durbin at msn.com (Andy Durbin) Date: Mon, 4 May 2020 16:56:46 +0000 Subject: [Elecraft] Upper limits of KPA500? In-Reply-To: References: Message-ID: When considering the upper temperature limit of a KPA500 I think it is important to know if, for the planned operating condition, the temperature limits at a value that the owner is willing to accept. In other words, does the fan produce sufficient airflow for the temperature to reach its maximum before thermal protection kicks in. If it does, what is that limiting temperature and is it acceptable? I have not tested any higher than 70 deg C and don't have any plans to do so. I don't want to operate there because the fan noise is intolerable. If I felt the need to operate in that region I think I would duct a much larger fan/blower to the rear chassis fan opening. Data from one of my test runs shows the front left heat sink fin was only at 47 deg C when the finals peaked at 70 deg C. The heat sink temperature continued to rise after TX stopped and peaked at 48 deg C. This suggests to me that the thermal path between the finals and the heat sink could be improved but I have no expertise in this field. 73, Andy, k3wyc From augie.hansen at comcast.net Mon May 4 13:11:41 2020 From: augie.hansen at comcast.net (Augie "Gus" Hansen) Date: Mon, 4 May 2020 11:11:41 -0600 Subject: [Elecraft] [OT] dumb question about oscilloscope probes In-Reply-To: <67a8ad9e-b1af-9cad-3089-716a3f3e2067@gmail.com> References: <67a8ad9e-b1af-9cad-3089-716a3f3e2067@gmail.com> Message-ID: On 5/4/2020 7:47 AM, Victor Rosenthal 4X6GP wrote: > ...

In-Reply-To: References: Message-ID: Mike, On my main PC, I use a StarTech USB sound dongle: https://www.amazon.com/gp/product/B00F7120TQ/ On my Chromebook, I used this device: https://www.amazon.com/gp/product/B01J7P0OGI/ but it's unavailable now. Others have used the Sabrent USB audio dongle just fine. I have one, but I haven't tried it because the others worked. https://www.amazon.com/gp/product/B00IRVQ0F8/ The key is that you need a USB sound dongle, and two 3.5mm TRS patch cables to connect the dongle to your KX3's mic in and speaker out jacks. It's a crossover connection -- the mike jack on the KX3 goes to the speaker out on the dongle, and the speaker out on the KX3 goes to the mike in on the dongle. If you've ever done any RS-232, it's like crossing over the TX and RX lines. I use the shortest audio cables I can easily route, and get well shielded ones of good quality. Don't cheap out on them and get 20 for $5 flat cable jumpers or something, get decent cables. That's to keep stray RF from getting into your audio lines. You MIGHT have to add some clip-on ferrites to them as well, depending on your grounding and bonding situation, and whether or not you get RF in your shack from your antenna. But that's a long and involved discussion that I STILL can't get through without scratching my head. The SignalLink will WORK...but it's basically just a very expensive external sound dongle. The KX3 should have come with a USB to 3.5mm control cable. That goes from the KX3 to the computer, so you can use CAT control to key the radio. (Some people just use the VOX setting and skip the USB interface cable. I use CAT because it works with my other programs better.) Does that make any sense? I think I'm rambling a little... -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Mon, May 4, 2020 at 1:18 PM Barry wrote: > Mike, > The simplest way I discovered was to use a SignaLink USB with the > cable for the KX3.

Based on the manual definition, 10 minutes out of every 15 can be in transmit. That seems to constitute 100% duty cycle for the KPA500.

Message-ID: <202005041902.044J2nBi019823@mail42c28.carrierzone.com> That seems excessive (shows good engineering). FM seems to be the hardest mode on amps. If you are long-winded probably exceed 3-minutes which is common Time-out-timer limit on commercial FM gear (and several ham rigs, too). I have a fan switch on my 150w 2m amp and too often forget to switch it on when operating FM. My 222 FM 30w radio has built-in TOT which shuts off Tx at 3-minutes of transmit. On my QRO sspa's I try not to do any key-down tests over a minute in length (and they are designed for JT65 service). Having overtemp protection and SWR protection is good insurance for protecting those expensive components. All my amps have that. Maybe someday I will own a KPA500 (do very little HF and have a 1000w 6m sspa). 73, Ed - KL7UW I once blew up a 500w dummy load by excessive transmit time running 1200w. Had that old Sierra MW for about 30-years. Now have a surplus 500w Bird dummy.

In-Reply-To: Message-ID: There are 3 kinds of digital operation you might want to use: wsjt-modes (FT8, FT4 etc.), RTTY, and "Sound card modes" (PSK, Olivia etc.). The setup for all of them is similar. For sound cards (useful in all 3 kinds) a cheap USB "sound card" is all you need. I started with a SignaLink years ago, but now I have a cheapie I impulse bought from Amazon more recently for about $5. The "headphone" output will drive the Mic input of the KX3 nicely with a 3.5mm to 3.5mm stereo cable. For driving the sound card Mic input from the headphone output of the KX3, I found I needed a pad to reduce the drive. I have a 47K resistor in series with the line from the KX3 Phones jack and the tip of the plug which goes into the sound card, and a 1K resistor between the tip and the sleeve. These resistors fit in a 3.5mm plug. The values were based on what I could find in my junque box. For the wsjt-modes, it is best to have CAT control of the radio from the computer. For the KX3, the USB to 3.5mm plug used for updating the firmware is all the hardware you need. Then wsjt-x will set your radio correctly when you select the band in the software. For RTTY, if you are good with CW and a paddle, you can do the whole thing with the KX3. Depending on your computer software, you can also treat it like any other sound card mode. Or your software can depend on the KX3 encoder/decoder and use CAT commands for sending and receiving. Most people doing RTTY from a computer like to use the AFSK or FSK modes. For the other sound card modes, use DATA A, and either use the CAT interface to key the radio for transmission, or use VOX on the radio. Getting your computer software connected to these hardware interfaces depends on which OS you are using. I use a Mac, which just means selecting the correct interface in the setup menus in the programs. I have heard complaints from the Windows users that software updates make it necessary to redo these connections. I haven't tried the Linux world. Getting the sound levels set correctly is another issue, since there are frequently as many as 4 (computer program, OS, sound card, and KX3) level controls. On reception, try setting everything about the middle of the range, and then aim for the highest level that won't overload the A/D converter in your sound card. This setting is straight forward in wsjt-x. For output, again try to set everything to about the middle of the range and then set things so the ALC indicator is showing 4 bars with the 5th one flashing. One gotcha is that when severely overdriven, the KX3 will show 0 signal rather than maximum, so if you're having problems, start low and work up. Good luck at Gitmo and maybe we'll see you on the air. 73 Bill AE6JV On 5/4/20 at 12:21 PM, w1srradio at gmail.com (MIKE W1SRR) wrote: >so rookie question as I just got my KX3 in time for mobilization (my call >sign will be KG4MA, wink wink) I want to setup my KX3 for FT8/FT4/JT9/JT65. > >Will have a brand new laptop and of course my radio what all are you using >for sound cards and settings on the KX3 and WSJT? > >If all possible I would like to get a Raspberry Pi computer to lighten the >load a bit, is that possible? > >Thanks in advance > >Future KG4MA (in mid june) >Mike --------------------------------------------------------------------------- Bill Frantz | If you want total security, go to prison.

I've been using the 3 for a few years on my kx3. I'm actually considering going to a winkey and external paddle so that I am able to get N1MM functional. I'm actually a little frustrated with the present 3 paddle. From a convenience point of view it is great but I have a persistent recurring problem of incorrect responses. Sometimes i think it may be due to dirty contacts and sometimes stray RF? I dont know which. I always remove the key after use for storing. I clean the contacts regularly. Sometimes it is a joy to use, and at other times not so much. Maybe this is common to all paddles? I'm not a heavy user or super CW op. I've posted the issue before. Have fun. I guess everyone eventually uses multiple keys in the same way we have multiple antennae. Brian VE3GMZ Sent via BlackBerry Hub+ Inbox for Android ? Original Message ?

A larger gap so there is more 'swing' for the contact will help. Now I use a small burnishing wand and clean the contacts each time I install the paddles on the KX2. Works well.

In-Reply-To: References: Message-ID: This is a newer version of the one I have been using for years now. https://www.amazon.com/dp/B076PC4VV4/ref=dp_cerb_2 It has a dedicated line in port so the level is not so touchy. Actually with the sound card and Elecraft USB cable it is a very simple setup. Set the sound out level on computer settings for the USB card to something a little less than half way, set the input (transmit) level in the software a little under half way and adjust mic level on radio to get 4 bars of ALC with the 5th bar just flashing. If the mic control seems too sensitive decrease one or both of the other levels a bit more. Use the volume control and rf gain to control the receive level from the radio. You do not want to saturate the waterfall display but need to have enough level to show the signals on the band. You can set the power level on the KX3 to 0.0 watts for level setting so you don't QRM anyone. Without an aftermarket heatsink I believe the recommended power out max is 5 watts, I am usually running the amp at 30 watts or so because when I use this setup I am usually on the road in a motel or park with temporary antennas. I don't like vox for keying, I know it is simple to use but so is telling the software to key via CAT. On Mon, May 4, 2020 at 2:46 PM Tox wrote: > I have a signalink I haven't used in years.

At looong last when organizing those extras tonight, I found my K2/10 cover (later replaced by the K2/100 cover). On the inside with a Sharpie is written 'Built by Mike Markowski AB3AP Apr 7, 2005'. Fifteen years! Wow. Time really does fly when you're having fun. Looking forward to the next 15, Mike ab3ap PS I also found endless "Packed by Christine" slips. :-) From frantz at pwpconsult.com Mon May 4 21:23:40 2020 From: frantz at pwpconsult.com (Bill Frantz) Date: Mon, 4 May 2020 21:23:40 -0400 Subject: [Elecraft] "2" or "3" Paddle In-Reply-To: <1588633719.59467816@webmail.coastside.net> Message-ID: When I built a single lever paddle, I used silver wire for the contacts since I had heard that all the normal corrosion products of silver are also conductive. I haven't had any problems with it, although it doesn't get much use. It might be worth while looking for a paddle with silver contacts. 73 Bill AE6JV On 5/4/20 at 7:08 PM, huntinhmb at coastside.net wrote: >The KX2 appears to be designed for very low current through the >paddle contacts.

It was and is the only radio I have since getting back into Ham Radio after many years of inactivity. It is a wow radio and Elecraft support is excellent. You won't go wrong. I would add to your list an antenna analyzer. It will make your life alot easier. The ATU I would say is not an option, it is a must. The panadapter is a fabulous add on too, but you can always get that later. Get whatever key you want. You will get another no matter what you buy now. The forums are fabulous reservoirs of knowledge from experts. Good luck Brian VE3GMZ Sent via BlackBerry Hub+ Inbox for Android ? Original Message ?

I bought it for our RV trip in 2018, AK to MI (11K miles R/T). 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From dandrew1 at me.com Tue May 5 06:24:22 2020 From: dandrew1 at me.com (David Andrews) Date: Tue, 5 May 2020 06:24:22 -0400 Subject: [Elecraft] KX3 digital ops, MacOS Message-ID: <44105AB1-DDE7-4E3E-B361-C2F2FA2DEB80@me.com> Bill, thanks for your recent discussion on digital ops.

Hi Tommy, I designed both keys, but I prefer the KXPD2. I use a KXPD2 with the KX2 frequently and have never had a problem. We improved the design over time. It weighs less than the KXPD3, takes up less space when packed, and is shorter so when it?s used trailside, the paddle tips will be higher off the ground. The adjustment tool is ?docked? on the key as well so you can?t lose it. (Bonus feature: if you use it outdoors often enough, it?ll gradually acquire a slight amber tint that matches the LCD backlight color :) 72, Wayne N6KR ---- elecraft.com > On May 4, 2020, at 6:42 PM, Tommy Judson via Elecraft wrote: > > Well, gotta make up my mind on which paddle to order along with the radio.

The suite is for the Fldigi suite of software. It is written, compiled, and tested to work (run) on any computer that has a Windows, MacOS, or Linux operating system. The chief author of the software is Dave . The software can be found at his website or at Source Forge. There are user groups for each 'flavor' of computer that is in use. There might even be links to each of the user groups on his website: w1hkj at bellsouth.net. Fldigi does not, yet, send or receive any of the JTx modes (JT4, JT8, etc.) but it does have several modes that can deliver large amounts of data in reasonably short time and in limited bandwidth. Take a look at W1HKJ's site and at the Wiki and help pages there for more information. Good luck and enjoy.

WSJT-X for the "JT Modes" (FT8, FT4, etc) is fully portable and available on MacOS ( https://physics.princeton.edu/pulsar/K1JT/wsjtx.html). This will get you started on the current popular modes. fldigi is another popular program, I have used it on my Mac for RTTY during the BARTG Sprint, it isn't the greatest for contesting but does work for casual contesting. It can do RTTY and PSK and a bunch of other digital modes that I have never tried ( http://www.w1hkj.com/). The KX2 Utility also runs on MacOS ( https://elecraft.com/pages/kx2-fully-portable-transceiver-firmware-and-utility) You can use this utility to receive and send RTTY if you wanted to. These are some starting points, hope this helps! 73 de KJ5T On Tue, May 5, 2020 at 5:25 AM David Andrews via Elecraft < elecraft at mailman.qth.net> wrote: > Bill, thanks for your recent discussion on digital ops.

Set the MIC SEL to RP and turn bias on. For the KX3. the easy way is to just turn MIC BTN off and plug it in. That microphone needs bias, and it will be supplied by the digital DC that normally is used for the MIC Button functions. The harder way for the KX3 is to make an adapter (but it is not that hard) Be aware that, like most computer microphones, the tip and the ring of the plug are wired together - so if you make an adapter, you must use a stereo jack so the audio is not shorted to ground. If you make an adapter, you can include a connection for a PTT switch, but without that, you can put the KX3 into transmit with the XMIT button. 73, Don W3FPR On 5/5/2020 7:31 PM, Frank O'Donnell wrote: > Phone newbie here.

Your experience is unusual. In about 11 years, the only thing that has ever gone wrong with my CM500s have been a broken cable, which, unfortunately, is not replaceable. I'm kind of a klutz, so I'm hard on cables, dropping them, kicking them, etc. Perhaps it got broken in shipping? I've never used anything but VOX for SSB and digital modes.

Heil products are an example of better sound through marketing. They're more expensive because they spend a lot of money on advertising to convince hams they're worth it. They also claim to make pro mics. I've been a member of the AES Standards Committee WG on microphones for more than 25 years, in which virtually all major microphone companies are represented. No one from the company is listed as a member, and I've never met Bob Heil or anyone from his company. Hams seem to think that because he did sound for a major rock band that his mics were good. 73, Jim K9YC From frantz at pwpconsult.com Tue May 5 23:25:18 2020 From: frantz at pwpconsult.com (Bill Frantz) Date: Tue, 5 May 2020 23:25:18 -0400 Subject: [Elecraft] KX3 digital ops, MacOS Message-ID: I use RUMlogNG (free from the app store) for general and contest logging. It will also use CAT commands to transmit and receive in it's contest mode. For general digital use, fldigi and wsjt-x are probably the best at the moment. There used to be cocoaModem, which was generally better than fldigi, but it does not run on the latest MacOS release (32 bit vs. 64 bit issues). All of these are free downloads. Others like MacLoggerDX for general logging, which I haven't used and SkookumLogger for a contest logger.

The ring connector is not connected. Plug the CM-500?s mic plug in (as I do), and it will work just fine! Remember to enable bias on the rear panel Mic as W3FPR noted. The CM-500 is an excellent headset for use with the K3. You should get many years of excellent service form it. 73!

On the KX3, look in the manual for the MIC jack connections. It should tell you why you need to be aware of the situation that the CM500 plug can present. Walt Underwood K6WRU has presented a link to an adapter that will allow you to plug the CM500 mic plug into a jack leaving the other jack available for us as PTT. Use of that adapter does not require you to set MIC BTN to off. Be careful, not just any adapter will do - some are simple splitters that put both the tip and ring on both jacks. 73, Don W3FPR On 5/5/2020 10:43 PM, Frank O'Donnell wrote: > Thanks for the clear instructions from Don, and the helpful > suggestions from everyone else.

I am currently using one on a boom with shock mount, wind screen and foot switch just because I like hands-free operation ... and am too frugal (i.e.: cheap) to spend the $$ for a Heil equivalent. Are you familiar with this mic, and what are your thoughts? I get excellent reports with it on my (non-Elecraft) rig. 73 Lyn, W0LEN -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: Tuesday, May 05, 2020 10:19 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] CM500 headset on K3S and KX3? Heil products are an example of better sound through marketing. They're more expensive because they spend a lot of money on advertising to convince hams they're worth it. They also claim to make pro mics. I've been a member of the AES Standards Committee WG on microphones for more than 25 years, in which virtually all major microphone companies are represented. No one from the company is listed as a member, and I've never met Bob Heil or anyone from his company. Hams seem to think that because he did sound for a major rock band that his mics were good. 73, Jim K9YC ______________________________________________________________ From eseeliger at earthlink.net Wed May 6 08:41:10 2020 From: eseeliger at earthlink.net (Edward Seeliger) Date: Wed, 6 May 2020 07:41:10 -0500 (GMT-05:00) Subject: [Elecraft] Elecraft Technical Support Message-ID: <1595260433.344.1588768870719@wamui-scooby.atl.sa.earthlink.net> Has online Elecraft Technical Support stopped?

I used them for a while and tossed them into the pile of too much stuff I bought and don?t use. Replaced them eventually with an RS60CF, and never looked back. Cable sets for both the KX3 and K3(K4). And yes ? I know there are a lot of people who don?t like those, either. But I do. All a matter of personal choice, I guess :-) David Clark makes a small and inexpensive soft-case that fits them perfectly, too.

That is the same headset as the Yamaha CM500, but with an inferior dynamic mic. There is nothing inherently inferior about dynamic mics, especially for speech -- the vast majority of mics used in sound reinforcement and broadcasting are dynamic mics. But like any technology, some products are better than others. > It is normal for earpads to wear out. I replaced the pads on my Grado SR225e phones after five years. Yes. I replace earpads on my Sony MDR7506 periodically. For many things we wear, comfort can be important, and, with headsets, that depends on the size and shape of our heads and even our ears, as well as the design and manufacturing quality of the headset. For many years, I've slept wearing Sony MDR7506 phones listening to jazz, and I also use them working CW-only contests. I find the CM500 equally comfortable. 73, Jim K9YC From tson35 at icloud.com Wed May 6 13:58:14 2020 From: tson35 at icloud.com (Tommy Judson) Date: Wed, 6 May 2020 12:58:14 -0500 Subject: [Elecraft] Earpads Shedding In-Reply-To: References: Message-ID: <943B9CAD-4758-4947-B207-CF855450D967@icloud.com> ...earpads are flaking pretty badly, leaving little back bits around the home office/shack?

No, I've never heard of it. A story. A colleague in pro audio, excellent engineer, designer of sound systems in the US Senate, House, and White House, wanted to do a good deed for rock and roll churches who used a lot of mics. He imported mics from a company in China. Samples were great, so he placed an order. Production quality was VERY different. Like Baufong, we're talking $40-$60 for mics competing with EU mics that sell for $1,000 - $1,500. Quality companies like Shure and Switchcraft have long huge problems with counterfeits of their products, and counterfeit mechanical and structural parts have long been a problem for manufacturers. I remember reading about that in the aircraft industry more than a decade ago. 73, Jim K9YC On 5/6/2020 5:32 AM, Lyn Norstad wrote: > There is a (presumably Chinese) mic known as the BM800 which is marketed > under several different names.

Very comfortable, Softer and NO flaking. I replaced the pads on my Sony MDR-7506's with them. I especially like these Sony's since they have excellent high frequency response (better than the CM500's) which is perfect for my high freq hearing loss. Not sure if they'll fit, but somebody out there must make velour pads for the CM500's. 73, Charlie k3ICH -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Walter Underwood Sent: Wednesday, May 06, 2020 12:53 PM To: Elecraft Mailing List Subject: Re: [Elecraft] CM500 headset on K3S and KX3? My CM500?s earpads are flaking pretty badly, leaving little back bits around the home office/shack. They still work fine. I purchased them in December 2012. I see that the same order has Eneloop XX batteries and a LowePro Edit 140 case, so that was all ordered to go with my brand-new KX3. Comments on my blog post suggested the Koss SB45 as another alternative. This also has an electret mic, but somewhat different fit over the ears, and it is cheaper. https://www.amazon.com/Koss-sb45-SB-45-Communication-Stereophones/dp/B00081A2CW Do not get the Koss SB40. That is the same headset as the Yamaha CM500, but with an inferior dynamic mic. The mic connector on my Yamaha CM500 is labeled ?KOSS?, for what that?s worth. I noticed that when choosing photos for my blog post. It is normal for earpads to wear out. I replaced the pads on my Grado SR225e phones after five years. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On May 6, 2020, at 8:25 AM, N2TK via Elecraft wrote: > > I bought replacement ear pad cushions and earpad covers for Koss UR20, headphones on eBay a while back for $14.24.

Someone said Koss pads could work but that hasn't been my experience. I've found some '500s at estate sales where I snap them up. Currently the law firm where my fiance is employed is working from home and she's using a set on her computer to "attend" on-line meetings.

In-Reply-To: References: Message-ID: Chris, Your English is much better than my French! I hope you can understand the following: You have a Q19 that is not willing to work at the high frequency end of the PLL range. The proper thing to do is replace Q19 with a J310 FET that is better. Order one from Elecraft (email to support at elecraft.com) with the part number. What you can try is to add a small value capacitor (12 or 15pF) from U4 pin 1 to U4 pin 12 (ground) to see if that restores proper function. If you do not have a stock of small capacitors, use the 12pF in the K2 kit which you have not yet installed and order a replacement from Elecraft. Proper functioning thru-hole J310s have been a problem since Elecraft ran out of the old ones and found that they had been discontinued by the manufacturer. I know of one ham in Europe who used an SMD J310 as a replacement - but if you consider that, know that the basing is not the same and you would have to go from the data sheet to know which pin to connect to the holes. He mounted it on the bottom of the board. 73, Don W3FPR On 5/6/2020 4:44 PM, Christophe GIBERT wrote: > Hi!

The KXPD3 was bought at the same time as my KX3 and served well for several years. However I never "liked" it - found it clunky to send on and the sharp edge of the paddles bit into my fingers, so I was on the lookout... Then I tried the KPXPD2 at SeaPAC - and bought one on the spot. I have never used the KXPD3 again. As a point of reference, here in the home shack my preferred sending implements are not paddles at all, but Vibroplex Lightning Bugs - of which four sit on my desk as I type this...

In-Reply-To: References: <20200506135052.Horde.viQoU77FeVYaPizb417IhGE@www11.qth.com> Message-ID: History is more than a little ambiguous. Wikipedia ascribes the "first high-powered" Talk Box to Bob Heil [K9EID] for Joe Walsh, [WB6ACU] which was a 250 watt amp + hi-pass filter.? However, Walsh credits an EE and steel guitarist [Bill West] with inventing it. Peter Townshend claims to have invented a version of the Talk Box during a Who tour in 1976.? However, Bob Heil sold the manufacturing rights to Dunlop Mfr. building them to Heil's 1973 design standards.? Peter Frampton says he first heard a Talk Box in 1970, and that Bob Heil gave him a custom built one as a Christmas present in 1974.? He became proficient at it and is now often associated with it.? It appears that every musical performer since then has used a Talk Box and at least a few assert invention. I use a Heil ProSet IC however I'm rarely on SSB.? When I have been on, I often get unsolicited "great audio" comments, no doubt because of my sonorous broadcast voice as much as the proset. [:=)? I use a CM-500 when operating W7RN remotely but I've never done phone remote.? I find the ProSet to be a little easier on the ears with prolonged use than the CM-500, but both work well for me.? As has been mentioned, a lot depends on how you place the mic and how you tailor the TX response and compression.? I guess all microphones tend to accentuate the bass as you get closer and closer, exactly the opposite of what you want for communications. Electrets seem to be fairly immune to this, the old classic RCA 44-BX was notorious for the effect. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County > On Wed, May 6, 2020, 13:51 wrote: > >> Interesting that Heil is not represented commercially.

(And a heck of a lot of fun!!!) I've never recalibrated anything, as per the manual, there has been no need. I have done FW upgrade at least once and that is currently 02.38/01.37. Just started getting "ERR TXG" on 50 MHz. Have seen several values in the D=xxx message as well. Manual has: ----- Error msg: ERR TX Problem: Transmit gain constant out of range Troubleshooting steps: If this only occurs on one or two bands, there could be a problem with a band-pass or low-pass filter. Also try re-doing Transmit Gain calibration (pg. 33). ----- Did some bench testing with a dummy load. I checked and problem only occurs on 50 MHz. Suspect degradation. Would be nice to resolve before the June VHF! :-) Did not try redoing the transmit gain calibration, as the troubleshooting steps suggests otherwise. With tech support, got as far as the suggestion of reducing power supply sag. Did have some IR drop, especially on 50 MHz, so swapped for lower IR drop power supply cable. Confirmed bench supply itself isn't sagging. So, what I measure now: At 28 MHz RX mode measures 13.60 V on DMM (on outside of DC coaxial power plug), 13.8 V on KX3 meter, and 0.17 A on KX3 meter. At 28 MHz TX constant 4 W carrier measures 13.55 V on DMM (on outside of DC coaxial power plug), 13.4 V on KX3 meter, 2.18 A on KX3 meter and 1.2 to 1 VSWR on KX3 meter. At 50 MHz RX mode measures 13.60 V on DMM, 13.8 V on KX3, 0.19 A on KX3. At 50 MHz TX constant 4 W carrier measures 13.53 V on DMM, 13.3 V on KX3, 2.9 A on KX3 and 1.6 to 1 VSWR on KX3 meter. VSWR is better of course below 28 MHz. (Microwave dummy load.) Of course, I don't have baseline measurements from when I first received the radio to compare against. If anyone can make similar measurements of their KX3 for comparison, that would be very interesting. Want to know about TX current draw and the 1.6 to 1 VSWR. Manual specs "1 to 2 A typical in transmit". Current is on the high side of that at 28 MHz even with the power backoff. 3A on 50 MHz, though? And, yes, the PA temp climbs quite quickly. Needs to go in for repair? No problem with that if that's the thing to do. (Schedule is probably too tight for June VHF, and I'm sure the stay at home order doesn't help.) I can do some trouble shooting and component swap here, no problem. My biggest limitations are time (work seems even busier with stay at home) and lack of a body of knowledge regarding this specific radio. I haven't popped it open for visual inspection, yet. Probably should do that especially around the 6m filters and the active and electromechanical RF switches. If I don't have a backup rig, I'm either not a serious contester, or i'm wating for a K4. Not sure. :-) Again, this radio has been a ton of fun! A little sad to run into my first problem with it, but it's a field radio, and I don't expect miracles.

I have replaced the ear muffs with Koss's version. However, like Grant, I bought a RS60CF and have not looked back. Unlike Joe, I find them very comfortable, even after many hours in a contest. They cut out extraneous noise very well. The K3 TX equalizer provides excellent audio response. I use a pair of CM500's for portable work. So far, I've not had to use the spare set in spite of a lot of use and abuse. When we do Field Day for real again, I will likely use the RS60CF set to cut down on the inevitable background chatter the CM500 doesn't. 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ From wm5dx at yahoo.com Wed May 6 20:06:37 2020 From: wm5dx at yahoo.com (Mike Streeter) Date: Thu, 7 May 2020 00:06:37 +0000 (UTC) Subject: [Elecraft] Headphones.

That's a characteristic of nearly all DIRECTIONAL mics -- those that On provide a single rear opening the capsule to cancel sound from the rear. Variable-D mics, virtually all of which today are made by Electro-Voice, have multiple openings along the "handle" of the mic body to provide the cancellation, and they have very little of that bass build-up. The earliest made by EV was the model 666, called "the Buchanan Hammer" because EV was in Buchanan, MI, and Lou Burroughs, who along with Al Kahn founded EV in the '30s, demonstrated the ruggedness of the new 666 to broadcast conventions by driving nails with it. When Lou wanted to retire, they sold the company to Gulton Industries. Al took his share and started Ten Tec, across the street from their mic and speaker factory in Sevierville, TN. Al was K4FW. I worked him once, on CW, using one of his radios. I was mobile from a campground in AR. Shure and AKG both made variable-D mics for several decades, but I don't think they still do. Modern variable-D mics are the EV RE10, RE11, RE15, RE16, RE18, and RE20. Last I looked, only the RE16 and RE20 were still in production, but there may be new models since I was active in the biz. The RE20 is quite popular as an announce mic. https://www.electrovoice.com/product.php?id=91 I know of no variable-D electret mics. 5/6/2020 11:39 AM, Walter Underwood wrote: > If I was going to upgrade my headset, I?d start with headsets used by sports broadcasters and ENG teams. Those headsets are EXPENSIVE, the mics are low impedance PRO mics, and are designed to provide maximum noise rejection. IF they are electrets, they won't work with ham gear without a preamp that provides Phantom Power (NOT the same as bias). 73, Jim K9YC From jim at audiosystemsgroup.com Wed May 6 23:39:21 2020 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 6 May 2020 20:39:21 -0700 Subject: [Elecraft] CM500 headset on K3S and KX3?

Up to a certain limit, the output power increases with PA current quadratically. So the maximum dissipation may be below the max power, and decreasing power does not reduce dissipation much. Assume that at 600W KPA500 operates at 60% efficiency. 1000W total, 400W dissipation. Now reduced the power to 1/4 or 150W. The input current is reduced 50% to 500W. The dissipation is 350W, not much below 400W at full power. With KAP500, the dissipation at low power can actually get worse than predicted since the power supply is unregulated and has higher voltage at lower current. Reduction of dissipation at low power can be done at least 2 ways. One is reduction of voltage as done in SPE amps. The other one is changing the the transformation ratio of output amp, e.g., in KX3; hard to do at high power. One can have the action of a different transformation ratio with a manual tuner. Once my 20A power supply died but I had a 5A supply available. But the max power was only 5W before the power supply switched off. 1/4 curent = 1/16 power. By adjusting a manual tuner for max output I got 20W. But KPA may not let this trick go because of SWR. protection.

Message-ID: <202005071742.047HgRv1022906@mail47c28.carrierzone.com> A couple years ago I bought the CM500 based on al the nice comments by others on this list. They failed me terribly; set up howling like a banshee minute I put them on (over my hearing aids) and not even connected to the radio. My hearing so poor that the amount of gain in my hearing aids fed back inside the acoustics of the ear-piece. No amount of fiddling with the headset stopped the feedback, so went back to wearing my Sony MDR-V600 stereo headset (which work well with my hearing aids). One if you bought the new CM500 from me for a nice discount, so I didn't loose out completely. I got a lot of advice back then which did not help/fix the problem (not wearing the hearing aids and turning up radio volume was one). In stead, I found a boom mic that attached to my Sony headset via an earth magnet "thingy" and that got FB audio reports. The mic has a foam wind-blast reducer and selectable omni or cardiod pattern pick up. Haven't really used the combo as I normally use my Heil desk mic in the shack. The boom mic was obtained for operating portable outdoors. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From macymonkeys at charter.net Thu May 7 13:46:48 2020 From: macymonkeys at charter.net (Macy monkeys) Date: Thu, 7 May 2020 10:46:48 -0700 Subject: [Elecraft] Headphones In-Reply-To: References: <00c901d62416$bada56c0$308f0440$@com> Message-ID: <3E1FE146-77EC-4219-8460-B24A1ACBDAA9@charter.net> 100% Bose QC25 here.

OK, the RS60CF is a Radio Sport head set. :-) I used one of their headsets during our club's CQP county expedition. I liked the isolation from ambient room noise. Yes, it squeezes your head, but I could wear it for several hours at a time without feeling I was getting close to the end of my tolerence. I didn't use VOX at home in CA because my radio was set up in the family room with 20+ feet of space between the backs of the equipment and the front door. (Nice for moving wires.) My wife frequently would walk up to the radio and ask a question and I didn't want the answer going out on the air. :-) I did use VOX when I did a multi-op WPX contest at K9YC's QTH. In that isolated environment it was more convenient than my footswitch at home. Doing the contest was also a whole lot of fun, and watching the other ops was a excellent learning experience. What I'll end up doing here in NH is still up in the air. 73 Bill AE6JV On 5/6/20 at 11:39 PM, jim at audiosystemsgroup.com (Jim Brown) wrote: >On 2020-05-06 1:16 PM, Grant Youngman wrote: > >>Replaced them eventually with an RS60CF, and never looked back. > >On 5/6/2020 4:52 PM, Joe Subich, W4TV wrote: >>A heavy, bulky, "head squeezer" for more than five times as much >>as the CM500 ... > >Yes.

Differing hearing loss between ears is quite common, which suggests that it could be useful for the new K4 to incorporate the ability to EQ left and right headphone channels separately! I've often recommended to ham friends with hearing loss to use the K3/K3S/KX2/KX3 to compensate by massive cut of low audio frequencies and massive boost the the top bands, and guys have told me that it helps a lot.

If you use Bose QC35s with Bluetooth there is a delay that increases over time. No problem listening to music. But if you watch TV the delay becomes intolerable. For BT use to watch TV you want a set using the Qualcomm APTX LL (low latency) codec. The Bose 700s don't use the APTX codec yet they don't have the delay of the 35s. So there's likely more than one LL codec. Delay is not an issue when using a cord vs BT. 73 - Steve WB6RSE On May 7, 2020, at 10:38 AM, Ken Widelitz wrote: I recently received the Bose Quiet Comfort II headphones as a gift.

If the feature is added to the K3/K4 to adjust EQ by ear, the AF should be able to be adjusted by ear also. Maybe a menu item that lets you select which ear gets some additional DBs. Using the Heil PRAS in my left ear only, I adjust the volume until my preferred CW tone frequency is centered in my head. I have always been very careful about headphone volume. My hearing loss was caused by a virus, so my being careful didn't save my hearing. Now, I'm sure my left ear volume is at a dangerously high level, but I'm already mostly deaf in my left ear, so I'm not concerned about it. 73, Ken, K6LA / VY2TT On Thu, May 7, 2020 at 12:19 PM Erik B wrote: > I second the suggestion that RX EQ be separate for left and right sides. > Almost a year ago I was diagnosed with a severe hearing problem on the L > ear > only, where some high freqencies are exaggerated but the normal speech > frequency range is severely attenuated.

If you want to consider aids, go to Costco. They sell very good stuff at half the price of audiologists, they have first rate test equipment to check hearing and to adjust aids to fit individual needs. My XYL has aids from them; I sat in while they counseled her and adjusted her aids. In my professional life designing large sound systems, I had to learn a lot about the mechanisms of our hearing system and hearing loss, and I regularly used test equipment to adjust large sound systems. It is from this background that I can attest to the quality of Costco's performance. I was first pointed to them by W6OAT, who has worn aids for many years. I know other hams who have bought aids from them. When you talk to them, make sure they understand that you work with earphones -- that will influence which of several types of aids will work best for you. 73, Jim K9YC From k2asp at kanafi.org Thu May 7 18:18:53 2020 From: k2asp at kanafi.org (Phil Kane) Date: Thu, 7 May 2020 15:18:53 -0700 Subject: [Elecraft] Headphones In-Reply-To: <005d01d624a4$225bdb10$67139130$@cox.net> References: <00c901d62416$bada56c0$308f0440$@com> <5bd66530-09fc-ae30-8f30-a485e340c7b9@audiosystemsgroup.com> <005d01d624a4$225bdb10$67139130$@cox.net> Message-ID: On 5/7/2020 12:17 PM, Erik B wrote: > I am so far resisting hearing aids, as my R side hearing is fine.

I've done the same. I'm using variations with a vertical post that clamps to a desk or tabletop, with swing arms as you describe, and also with a fitting without the arm that allows adjustment of height and rotation in both horizontal and vertical plane. 3-4 years ago, I found a couple of Samsung models that could accept the standard VESA mount, designed for 14VDC, and that run just fine from the 12V system in my shack (so I could dump their noisy SMPS wall warts). Those models are long discontinued, and most current models run on higher voltages. 73, Jim K9YC From n6kr at elecraft.com Thu May 7 19:55:26 2020 From: n6kr at elecraft.com (Wayne Burdick) Date: Thu, 7 May 2020 16:55:26 -0700 Subject: [Elecraft] height of k4 with legs extended In-Reply-To: References: <001501d624a3$8b45e090$a1d1a1b0$@elecraft.com> <8a808d5c-6a2e-eb0d-5a42-d6c8439ab918@coho.net> Message-ID: <95D38F6B-5518-4E79-81D6-7A558E4D0105@elecraft.com> On a related note: Because the K4 has a touch screen, desktop usability is greatly enhanced by having the screen tilted away from you.

I am hearing impaired and have not found a "truly compatible" over the hearing aid solution. The best one for me so far is the Sennheiser S1 avionic headset (no longer available). I happened to have one from my flying days. It has the best TX and RX noise cancelling function I have found. It is a shame that Sennheiser did not continue them. I have not played with the Bose or LightSpeed sets since my early experience with both being too tight. I have used the Sennheiser PXC 550 II set with the Kenwood D74A BT feature and gotten good voice reports. They are also OTE and good for those of us with larger hat sizes, but did not work acceptably without taking off the hearing aids. They do work without a lot of BT lag so might be acceptable for CW. I never used either with my KX3.

Then set "tun pwr" to nor, select desired power out, and long press XMIT to send a carrier and see the current. (do not TX at exactly 5 or 50w as that will cause a TX gain calibration). That will give you a close reading. The RX current depends a lot on if you have a sub receiver or 2m module but you can watch RX current and change options to see the changes. If you design a system for 2Amps on RX and 25a on TX, that would give you plenty of overhead. Keith WE6R Elecraft K3 Tech.

It may be possible to automate that, but I don't know how. And if you could automate it, note that these Remote apps power up the amplifier as they start up, leaving it running. That's OK if you just rebooted the server yourself. But if it's auto-booting, for example after recovery from a power failure, it could leave the amp running for days before you next sit down at your control site to operate. Maybe you don't care, but I prefer to leave unattended amps powered down when not in use. Or am I missing something? 73, /Rick N6XI On Thu, May 7, 2020 at 5:06 AM Lyn Norstad wrote: > Frank - > > I have both the KPA and KAT500 utilities set to do this, along with my > browser (Chrome) set to QRZ.com on one of my Win 7 systems.

This feature is very convenient on the K4, with multiple lines of received text, and the ability to use a keyboard (wired or wireless) at any of the three USB-A jacks. You can also transmit in any of these modes by sending CW with the keyer paddle. At present the K4 can handle PSK31, RTTY, and CW, as on our other transceivers. We hope to add other in-box text modes in the future. I was happy to discover lots of activity in all three modes over the past week. PSK31 -- which provides below-the-noise-floor copy -- is found primarily on 20 meters from 14070-14073, and I've also heard it on 80, 40, and 15 meters. RTTY is common (especially during weekend contests) around 14080-14090 or higher. And of course there's CW at all times of the day or night. Weekly CWT contests are a big draw these days. Each of these modes has its idiosyncrasies. But one thing they all have in common is that they're conversational -- you can carry on real QSOs. They can also be used in contests, with no "canned" limitations on exchanges as with heavily automated data modes. I encourage everyone to give these modes a try. If you have a K3, K3S, KX2, or KX3, you can use all three. Decoded text is scrolled across the VFO B display as signals are tuned in.

I haven't spent much time on 10M since receiving the KPA1500 in late 2018. Recently, I was working a small opening on 10 in the FT8 mode. I noticed the noise floor on the P3 (& S meter on the K3) go up from -130 to -115 or so when the KPA1500 was switched on. The 10M ant was pointed right at the shack. I found the thread on the mail reflector from Dec 2019 (partially quoted below) & tried all the suggestions offered, etc with no relief. The noise is definitely being picked up by the antenna. With a dummy load connected to Ant1 by 3' of LMR400, the P3 level is well below -130 with the amp either on or off. I then used a "RF sniffer" set for 28.2 Mhz calibrated in dBu to check the cabling, grounds, AC input cabling, etc. The source of the noise (measured 30 dBu +) was along the DC power cable to the Amp deck from the power supply. Other cables were below 10. The power cable is factory supplied, 6 Ft long, & approaching 1/4 wave at 28 Mhz. The serial # of my amp is 315. Any suggestions for remediation of this issue will be appreciated! I installed a #31 mix clamp-on ferrite right at the back of the Amp deck & it dropped the noise comsiderably. When moved down to the PS case, it did not help. Seems that noise is from the Amp deck & not PS. 73 Gill W4RYW From marklgoldberg at gmail.com Sat May 9 16:32:45 2020 From: marklgoldberg at gmail.com (Mark Goldberg) Date: Sat, 9 May 2020 13:32:45 -0700 Subject: [Elecraft] Headphones In-Reply-To: References: Message-ID: Have you contacted Bose?

Why did the FCC put #2 in there? I'm from the avionics industry. We have to not produce unwanted RF interference and we have to operate correctly in the presence of high levels of RF. Especially in recent years, someone could put their phone down on top of your unit and subject it to huge fields. We test in fields of hundreds of volts per meter and have to work. My products also have to work with 4V of ripple on the power input with no effect. Bose knows how to design for these environments. I was on regulatory committees with people from Bose and they were very sharp. So, if they are not obligated to fix this, I was just suggesting that they still might if contacted and that they have the knowledge to fix it. 73, Mark W7MLG On Sat, May 9, 2020 at 8:06 PM Phil Kane wrote: > On 5/9/2020 7:08 PM, Nr4c wrote: > > > Beg to differ.

I am not a lawyer. Your equipment had to operate too much more stringent requirements because human life is at stake. The part 15 "must accept" clause says that if you are being interfered with on your Part 15 device, is it not legal grounds to award damages in a court case. It won't keep someone from from filing a suit. But without that clause we hams might be hauled into court by every one who is interfered with. We have been, but Part 15 has kept the practice from proliferating. Devices sold under part 15 are not used in situations where human life is at stake. Well they probably are, but are not designed specifically to operate that way as are aircraft radio and navigation systems. In addition, the "must accept" clause releases hams from the legal and financial obligations to correct the problem. I should think that it also releases the manufacturer from that also. I'm not a lawyer. It's just my take on it. 73, Dave, K4TO On Sat, May 9, 2020 at 11:38 PM Mark Goldberg wrote: > I do want to understand what "must accept" means.

I have cobbled up a command script that facilitates boot-time startup of these "Remote" Host applications from Elecraft. The script will launch any of the three Remote applications you want, and can easily be wired into the PC Startup sequence to survive PC restarts.? Also, the script supports two instances of each type of device -- for those doing SO2R remotely. For example, with one click, you can launch both of the applications for the KPA500 and KAT500, and have them start into Remote Host mode. If you are tired of using TeamViewer to restart these applications, it is worth a look.?? I have included a basic set of instruction steps that describe the extra requirements for IP addressing, Port Forwarding, and getting the script to launch at boot-time. Expert users can skip that stuff and go right to the configuration area of the script. I called it Kstart-RemoteHost.? I have it published on github. https://github.com/KD4Z/Kstart-RemoteHost Let me know if it works for you.? If you like it, buy me a beer.

But it's not commutative -- just because the Part 15 device "must accept" interference doesn't mean that owners of other devices under different parts of the law "must accept" interference FROM Part 15 devices. It's not a case of *modus ponens*, where if A implies B, then B implies A. So if I have a case of a Part 15 device causing spurious signals on my HF station, then the Part 15 manufacturer should DEFINITELY be informed, since while they must accept interference from my HF station on their headphones, I do NOT have to accept interference on my HF station FROM their headphones. They have to keep their spurious radiation in bands operated by other services within the specifications. This is why there can be FCC enforcement procedures against grow lamp manufacturers and wall wart manufacturers because of interference in Amateur bands generated by those consumer devices. The attached FCC bulletin would seem to corroborate my understanding. So would this paragraph from the ARRL site on FCC Enforcement Actions specifically about Part 15 devices interfering with amateur operations: *"The FCC Part 15 regulations are clear that the manufacturers of unlicensed devices must meet the appropriate conducted - or radiated-emissions requirements and that the operators of those devices are responsible for resolving any harmful interference to radio services that might occur from their use."* IANAL, and I didn't stay at a Holiday Inn Express last night. https://transition.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet63/oet63rev.pdf -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Sun, May 10, 2020 at 7:27 AM Dave Sublette wrote: > The answer to your question seems obvious to me.

In general, most hum is magnetically coupled, while buzz is power line leakage currents, aggravated by by Pin One Problems and failure to do proper bonding. 2) Make sure that the adapters you got are actually doing what you think they are doing (or that you want them to do), checkin them out with an Ohmmeter. 3) Make sure that bias is turned on -- the mic in CM500s is an electret, which requires bias. 4) Make sure that Mic Gain and Comp are not turned up too high.

Neither did I, but I am a lawyer who deals in this area. Part 15 sets the minimum standard for RF emissions from devices that do not require individual or blanket station licenses. If they don't comply, they can't be used legally or be marketed (a "term of art" that covers manufacture, sell, offer for sale, ship, modify, and in some cases, use). Compliant devices must be certified by the manufacturer and labeled as meeting those standards. There are certain exemptions for home-brew ham equipment and school projects. Regulatory law is clear - even if the emissions from a device comply with the levels mandated in Part 15, if they cause harmful interference (another "term of art") to licensed/authorized communications, the operator of the Part 15 device is required to cease such operation until the interference is abated. Conversely, as many have noted, if the Part 15 device gets interfered with by signals from a licenses/authorized station or device, it's "tough". What part of "must accept" is not clear? A good part of my early legal career was devoted to assisting and defending hams against claims of interference to consumer-level entertainment equipment. Much of that has gone away, because the European Union has regulations about how such equipment must reject outside signals and reputable manufacturers are adhering to those standards if they want to sell in the worldwide market. The FCC has kicked around establishing similar standards for decades with no action, relying on the broad "must accept" to protect the public. When is the last time that we here have had to deal with a substantial claim of causing TVI ("Tennessee Valley Indians)?

The only missing part that I am aware of is the one pin connector which is soldered to a K3 main board. This connector is NOT needed for a K3S.

In the initial test, which produced the hum, the power source for the KX3 was a Pro Audio Engineering PAE-Kx33 low-RFI supply. This PSU was plugged into the same outlet as a variety of other shack gear, some powered on. The only other things connected to the KX3 were (a) an antenna intended for field use, and (b) the CM500. I noticed that when I touched the shield on the antenna coax's BNC connector with my finger, the hum diminished substantially. I then unplugged the PSU and replaced it with a car battery charged to 12.01v. Now the hum appeared to be completely gone. So, if I were to keep using the KX3 within the shack, it sounds as though a thorough grounding/bonding workup would probably fix the problem. I'm in the process of working through http://k9yc.com/GroundingAndAudio.pdf. I was mostly curious why the CM500's mic produced the hum, but the handheld mic that came with the KX3 didn't. The CM500 has a quite long cable, and I wondered if that could be part of the problem.

More obvious questions I should have asked -- Exactly what is your antenna, including any counterpoise? How long is the coax? How far from the shack? Is there a serious choke (per my cookbook) at the feedpoint? Is it possible you have a bad piece of coax or a poorly installed connector? Is your shack bonded? It should be, regardless of this problem. 73, Jim K9YC From kb1tcd at gmail.com Mon May 11 08:09:09 2020 From: kb1tcd at gmail.com (JP Douglas) Date: Mon, 11 May 2020 08:09:09 -0400 Subject: [Elecraft] Hum on TX audio w/ CM500 headset on KX3 In-Reply-To: <545436f2-fc7c-3878-d625-72cf739ee15e@audiosystemsgroup.com> References: <4799515b-2416-19a9-70ab-0f9fb9909c19@inkbox.net> <1754211b-e8bb-a851-9133-e0b154f93c8e@embarqmail.com> <545436f2-fc7c-3878-d625-72cf739ee15e@audiosystemsgroup.com> Message-ID: <8B00F879-A949-40E9-A10A-C1E887BC8C78@gmail.com> Hello, inmates! not all mics on the Yamaha CM-500 headsets are electret, I tested mine before making the connectors; I am not using it w/my KX3, using w/Kenwood TS-480 and Yaesu FT-897.

The setup was complicated and I changed computers and other station equipment and have not used it remotely for about the last five years. I bought the MFJ1234 about a month ago and now have it set up and working. I was able to set up 15 macros on the MFJ1234 and now have only the one connection to the K3s and can leave it hooked up while using both local and remote control. The only problem I see is I need to change the MIC SEL from rP.L b1 A5 to Line I n for remote control. I have not found a way to set up a macro to do that. That would be my first wish is if someone knows how to set up a macro to make that change if I forget to do it before I leave home. The other option would be to get the K3 UTILITY program to run on the MFJ1234. I was able to download the program to the MFJ1234 but can not figure out how to install it and make it run. I have already been able to set up configuration files on my Windows 10 computer for both setups and think I could do the same thing using the RASPBERRY PI remotely. Does anyone else know if the K3 UTILITY will run on the RASPBERRY PI and if so how do I install it and make it work? This was complicated to set up but works much better than what I used several years ago. I can work 7 bands from 160 to 10 meters both SSB and CW using it. I can work CW without that last step but I would like to be able to fix my problem if I forget to do it before I leave the house. All I have to take with me is my iPhone. Thanks for any advice.

There is NO problem connecting a pro dynamic mic, which is balanced, to an unbalanced input. All it takes is a simple adapter, XL-female to 1/8-in TRS plug. Connect pin 2 to the TRS tip, pins 1 and 3 to the TRS sleeve. Make sure that Bias is OFF -- dynamic mics don't like DC. There is no easy way to connect a pro balanced ELECTRET mic to an unbalanced input. 73, Jim K9YC From tson35 at icloud.com Tue May 12 07:32:51 2020 From: tson35 at icloud.com (Tommy Judson) Date: Tue, 12 May 2020 06:32:51 -0500 Subject: [Elecraft] Rig forCW In-Reply-To: References: Message-ID: Good Morning, I have a simple but difficult question for the CW ops.

It?s a fun rig, works well, but if you can have only one get the KX3. And as a side note the Elecraft antenna tuners, in rigs or separately can?t be beat. They will tune a wet noodle if that is needed for your ham radio experience. They almost make you think your really lousy antenna is the greatest because they will tune it, but again, if the results aren?t what you want it?s probably a poor antenna and the tuner is making it look better than it is. Make a good antenna first and then use a tuner to take the pressure off your finals or expand the bandwidth. Dave K8WPE David J.

The KXFL3 is actually 4 different filters that are shared between Phone and CW modes.

If so, adding capabilities up to 100 watts via an external amp is pretty simple. If you?re going to be adding more power, and don?t plan on using the portability of the kx3, consider a used K3/100 which has a lot more flexibility for narrow roofing filters, 100 amps built in and an easier path to adding a kw amp. 73, Lou, W0FK ----- St. Louis, MO "The difference between stupidity and genius is that genius has its limits."

If on the desktop, move it to the Applications folder. In Catalina certain directories are restricted - you have to give permission to access files there. This sounds like the app is unable to access some of its resources. By the way, you have two of us who are associated with Elecraft involved now. W4SMT is the application author. He knows the app inside and out. 73, Jack, W6FB > On May 12, 2020, at 9:58 AM, John Stengrevics wrote: > > Thanks to all for taking the time to help.

The question is where the pane is... John, I?ve had this happen to me before on other things?so launch the utility, go up to the top and under Elecraft K3 Utility, and choose ?About K3 Utility? Does the ?About" pane show up anywhere? And does it bring with it the actual utility pane with it, by chance? Like I say, this has happened before where opening something else in an app makes the app show up. Worth a shot. Regarding location of the app, yes it absolutely should be in Applications, but I just launched mine from Downloads and it still works. But moving it to Applications would be well advised. 73, David - N5DCH > On May 12, 2020, at 11:06 AM, Grant Youngman wrote: > > I don?t know guys.

So lets look at what 15-dB does with 10w; answer 316w. So if you bought a KPA500 might feel that's wasting its full potential. If you had a K3/10 or K3s/10 they put out 15w with the firmware upgrade. That would result in 474w. 474/600 is 1-dB. But then what is the cost differential between a new KX3 and a used K3/100? Guess other factors might make one more attractive over the other. My approach was a K3/10 and then a KX3, followed by a KXPA100. More expensive than a basic K3/100 but you can buy a new KX3 or KXPA100 but not a new K3s. In my opinion (whatever that's worth) the KX3 measures up with my K3 pretty well for basic operating (plus smaller foot print for the apartment liver). In full-out urban ham radio competition the K3 wins!

I've been troubleshooting seemingly anomalous power consumption when transmitting. My K3S pulls way more current on 20m than on 40m for the same input signal and output power. After some experimentation, I found that the input current is related to whether the KAT3A is engaged, and which values of C and L are selected. The lowest power consumption comes from the highest value for C and the lowest value for L, and the highest power consumption comes from the lowest C and highest L. Here's a chart of what I found going into a dummy load, manually setting C and L values: min C/max L max C/min L bypass not-inst 40m, 12w 3.55A 2.23A 3.4A 3.3A 20m, 12w 3.70A 1.99A 3.1A 3.0A 40m, 13w 11.5A 4.65A 7.3A 7.2A 20m, 13w 15A 5.63A 6.9A 6.8A If that chart doesn't render well on the list, here's a screen shot of it: https://imgur.com/GF4IUIy (This was transmitting a 1500Hz tone, SSB at almost 100% modulation with 14v supplied, and is the value reported by the K3s, though my ammeter reports a similar value. I get similar results with FT8 going into an actual antenna instead of a dummy load.) So I guess the question is this: is it expected to see such a large variance in power consumption for the same output power based on the values of C and L for the KAT3A?

Is the KAT3/KAT3A *tuned correctly*? Any solid state amplifier will draw more current if it is driving a low impedance load than it draws driving a high impedance load. If the KAT3/3A is transforming the antenna impedance to a low value, you will see higher current than you would for a proper 50 Ohm load. The only valid measurement is with a 50 Ohm dummy load attached to the antenna jack and the KAT3/3A tuned for the 50 Ohm load (or bypassed). You should *never* be operating with the tuner adjusted for other than 50 Ohms to the PA. > min C/max L max C/min L bypass not-inst > 40m, 12w 3.55A 2.23A 3.4A 3.3A > 20m, 12w 3.70A 1.99A 3.1A 3.0A > > > 40m, 13w 11.5A 4.65A 7.3A 7.2A > 20m, 13w 15A 5.63A 6.9A 6.8A You are comparing apples and oranges here.

For the dummy load, no, the KAT3A won't be tuned correctly when I manually choose values for C and L; I just used it as a way to better characterize the nature of the behavior that I was seeing and to reduce the number of variables. However, as I mentioned, the behavior is similar when running FT8 with the tuner correctly tuned for the antenna.

The KX2/KX3 with KPA100 has significantly more phase noise than the K3/K3S at 100W and when run through another external amplifier (KPA500/KPA1500/etc.). The KX3 has transmitted phase noise at (approximately) -122 dBc (@ 10 KHz) where the K3/K3S is (approximately) -135dBc (@ 10 KHz). This data is from the ARRL Labs as reported in the reviews of the specific rigs. Bottom line, the KX3/KPA100 (at 100 W) will have as much transmitted phase noise as the K3S/KPA1500 (at the legal limit)! 73, ...

The measurement horizontally - at least min C/max L and max C/min L - mean absolutely nothing because the tuner is not tuned properly. What do you see with: 1) a 50 Ohm load connected to the antenna port and the KAT3A bypassed, 2) a 50 Ohm load connected to the antenna port and the KAT3A removed (KANT3 board installed), 3) a 50 Ohm load connected to the antenna port and the KAT3A tuned for SWR = 1:1, 4) your "antenna" connected to the antenna port and the KAT3A tuned for minimum SWR? I do not have the tuner component values in front of me so I can't calculate the impedance you are creating by min C/max L and max C/min L but if the tuner has a 10:1 matching range you are running between at least 5 and 50 Ohms or 50 and 500 Ohms depending on whether the C is on the input output side of the inductor (basic L network). The roughly 2:1 difference in current is believable for the 10:1 impedance mismatch - particularly if the controller is reducing the drive (power output) as the mismatch exceeds 2:1 or 3:1. 73, ...

As a KX2 owner, if you did go with the KX2 you would not be unsatisfied if your desires were to operate QRP on 10-80 meters and planned to do portable work. Otherwise I would tend to agree with the others, the K3 is an excellent choice, I have used them in guest-op situations for contesting many times and they are fantastic radios. For the record, I considered the KX3 for a long time but opted for the KX2 because at the time I thought I would be doing way more portable ops, using it at home for QRP digital, some SSB and now adding CW into the mix I have been very pleased with it, take that for what it is worth. Sherwood puts the KX3 pretty high on the list, upgrading probably doesn't make sense for me but for a home station starting with the KX3 probably makes a lot of sense.

In both cases the ATU had no trouble making a 1:1 match. The actual measured SWR of the antenna system (ie, with an SWR meter) is 3.7:1 on 40m and 2.9:1 on 20m. Not a great match obviously, but expected for what it is. Nick -- *N6OL* Saying something doesn't make it true. Belief in something doesn't make it real.

Do you want 100 watts - then choose the K3 (or K3S). You can also add the P3 for a panadapter display. Do you want something small that you can tote in a backpack, then the KX2 is the obvious choice. You can use it at home with the KXPA100 for a 100 watt home station. Do you want something that is small enough for 'picnic table portable', but has more buttons and up-front controls than the KX2, then choose the KX3. It also can serve as a 100 watt home station with the addition of the KXPA100 and can also be used with the PX3 for a panadapter display. If you are planning portable work, the internal tuner is a must. At the home station, if you do not have resonant antennas, then you should have the internal tuner in the K3/K3S or the KXPA100. Those are the basics that I can convey, the choice is yours to make depending on your station aspirations. Try not to base your decision on price alone - decide what you want and then proceed from there. I have the K3 with the P3. KX3 with the PX3 and KXPA100 as well as the KX2. So I can say that they are all good, but for the home station, I usually go with the K3 with the KX3/PX3 and KXPA100 (with KXAT100) as an alternate. The KX2 is reserved for portable operation, and I use it rarely since I no longer go on hiking ventures. 73, Don W3FPR From rmcgraw at blomand.net Tue May 12 16:40:59 2020 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Tue, 12 May 2020 15:40:59 -0500 Subject: [Elecraft] K3S current draw relative to KAT3A settings In-Reply-To: References: Message-ID: I just ran quick tests on my K3S on all bands, first with the KAT3a bypassed and then with the KAT3a allowed to resolve a match.?

On 20m, I get 14.0A bypassed, 17.5A matched, a bit bigger delta than what you saw, but perhaps not totally unreasonable. The reported C/L values the ATU picked for 40 and 20 for this test with the dummy load are 0 nF / 0.5uH and 0.06nF / 0.25uH respectively. With my antenna, repeating the same test, I get 14A on 40m and 19A on 20m (both with the KAT3A matched), so around an amp more than with the matched dummy load. > As concluded from my tests, the radio will draw different amounts of > current on different bands for the same given and measured power > output. Seems normal to me. > Thank you so much for taking the time to run these tests. I appreciate it. I think the fact that we have a TX gain calibration per band also implies that we'd see some differences in current draw for the different bands too. What I was really trying to determine is whether the results I'm seeing are *typical*, and it sounds like the answer is "yes." I guess what caught my eye in all of this is how much the configuration of the matching network can affect the current draw of the amplifier. Not having a great deal of engineering experience with RF amplifier engineering myself, I kind of expected that presenting the amplifier with a nice 50 ohm load would have implied similar characteristics regardless of what sat on the other side of the network, vs causing the amplifier to draw another amp or two. My expectation was that we'd see *loss* through the presence of the matching network, but not so much an additional demand of current. Kind of interesting, but not, it seems, abnormal or unexpected. Thanks again for confirming! Nick -- *N6OL* Saying something doesn't make it true. Belief in something doesn't make it real. And if you have to lie to support a position, that position is not worth supporting.

Otherwise you are just seeing how much energy can be dissipated in your tuner. One way to do this is to use a dummy load and a manual tuner, set the manual tuner to deliberately give you the type of mismatch you want and then have the autotuner try to match it. doing it your way is just abusing your output devices.

I had another remote setup several years ago but it only had a few MACROS and for that reason and all the wires I had to hook or change to use it was nothing but trouble and I have not used it for the last several years. The MFJ1234 has 32 MACROS available and I have used 21 of them. Now I can walk away from my K3S at home without making any changes from my local use and set it up the way I need while at my camping spot. The feature I was asking help with last night was changing the MIC SEL on the K3s from rP.L b1 A5 to LI ne In . The MACRO I used for this is *0w MN053;UP053;MN255; I can tune the antenna tuner, set power, set the mic gain and compression, work CW from a keyboard etc. If I need more MACROS I still have several left that I can use. The hams in the area say I sound good on 160 meters SSB and one even sent me an audio recording that sounded fine to me. I find I can hear and be heard as well through the remote as I can sitting in front of the K3S. I only have two cables hooked up. The data cable to the router and the USB connection to the K3S and I can leave both of them connected all the time. This lets me listen in the middle of the night or walking on the sidewalk any time on my iPhone and I can even join in if I want. 73 Ken W0CZ Sent from Mail for Windows 10 From rmcgraw at blomand.net Tue May 12 21:10:53 2020 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Tue, 12 May 2020 20:10:53 -0500 Subject: [Elecraft] KX3/KX2 remote for FD In-Reply-To: References: <4A4BE0FF-F7DF-478A-81DC-F8A5C39EAE6F@arrl.net> Message-ID: With the current COVID-19 conditions, I'll be staying at home.

It is equally easy on the KX3 and KX2 between CW and voice, but when going use to data with an external computer I have to change the phones plug, the mic plug, and the mic bias.

Remote operating is as likely in a disaster scenario as any other-all depends on your infrastructure and whether you rely on conventional internet access or other networks. Nothing wrong with home operation or solo portable either. Field day this year is what you choose to do comfortably and explore options to keep you safe. Our setup is designed for near total isolation and no close contact with other operators. Oregon has strict guidelines that we?ll follow-so far we have the lowest rate of infection in the country and plan to keep it that way. Exploring remote operating will also benefit many hams that may not have access to larger antennas or quieter locations well beyond this particular event. If you want to know more about our plans I?m happy to discuss that off the reflector. So-what are options for remote control of the KX3 and KX2?

Did the basic trouble shooting with a dummy load.? Still no power out. Called Elecraft and they said that the low power amp was out. Did some on line research and found that when tuning up the external ant tuner at 5 watts it stresses the low power amp and they fail. Recommend that you tune up at 3 watts or less to keep from burning out the low power amp. By the way I did some online research and found this is a common failure with the k3.Sent via the Samsung Galaxy S8+, an AT&T 5G Evolution capable smartphone From tson35 at icloud.com Wed May 13 09:30:00 2020 From: tson35 at icloud.com (Tommy Judson) Date: Wed, 13 May 2020 08:30:00 -0500 Subject: [Elecraft] Establishing A New Station In-Reply-To: References: Message-ID: Good Morning Don, > Tommy, > > The KX2, KX3, and K3 are all fine radios for CW - and data modes and SSB > as well. > > Do you want 100 watts - then choose the K3 (or K3S).

The KX2 is the logical choice in this situation mostly because when back in my home in the 17th floor apartment in a 400 person retirement facility I?m not sure I will be able to operate. If I do it will be most likely be with an end weighted wire suspended off a balcony - it?s a hundred feet or so to the ground. So my permanent home will be the portable place and this country RV will be the more permanent place - especially until this coronavirus epidemic is better controlled. That virus delights in getting into large facilities housing the older more infirm population. There is only one case there AT THIS TIME.

There is no provision for a panadapter with the KX2. In your RV, the KXPA100/KAT100 can hide away somewhere away from your operating position - it does need a place where there is air circulation, it is cooled by the large finned heatsink and no fans. You will need extensions for the KX3 to KXPA100 cables. The separation with the stock cables is limited to about 18 inches. You will need a power supply - the SS30DV sold by Elecraft is quite capable for a 100 watt station. 73, Don W3FPR On 5/13/2020 9:30 AM, Tommy Judson via Elecraft wrote: > Good Morning Don, > >> Tommy, >> >> The KX2, KX3, and K3 are all fine radios for CW - and data modes and SSB >> as well. >> >> Do you want 100 watts - then choose the K3 (or K3S).

Thanks in advance for any assistance. ???????????????????? K-2 Sale All this talk about K-2?s makes me homesick for the one I built shortly before my retirement (Serial #5529). I spent an entire summer carefully following the instructions and created an astonishing radio. Sometime after that, the lure of the K-3 took over and I sold my K-2 to finance the purchase of a K-3. While I have enjoyed the K-3 and still use it regularly, I'm sorry to have parted with my K-2. If anyone out there knows who has my old K-2 please contact me off-list. I?d like to discuss reacquiring the radio. If you tell me you have the radio but it?s not for sale, just tell me how it?s doing.

If most of your operating is parking in a CW or digital sub-band and working that, a map loop should be great.

I don't need outside electricity, phones, internet or repeaters.

Remote operating is as likely in a disaster scenario as any other-all depends on your infrastructure and whether you rely on conventional internet access or other networks. Nothing wrong with home operation or solo portable either. Field day this year is what you choose to do comfortably and explore options to keep you safe. Our setup is designed for near total isolation and no close contact with other operators. Oregon has strict guidelines that we?ll follow-so far we have the lowest rate of infection in the country and plan to keep it that way. Exploring remote operating will also benefit many hams that may not have access to larger antennas or quieter locations well beyond this particular event. If you want to know more about our plans I?m happy to discuss that off the reflector. So-what are options for remote control of the KX3 and KX2?

Message-ID: Hey folks, This is a technical one where I'm not sure of the correct macro. Situation: K3s, Remote via RRC 1258, using the serial connection. However, we want an alternate remote that is supported by N1MM on the desktop. Therefore, I want to be able to switch between USB and RS-232 ports for rig control. When on the Remote, I can just use the K3/0 menu to switch to USB, at which time I'll lose rig control. Then, using Anydesk/Teamviewer/etc ... I can connect N1MM on the remote PC and play radio over the USB port. However, I won't have a way to set the rig back to RS-232 38400 to use RemoteRig again... Solution? However, there seems to be the RS232 MN057; macro, which gets you to the RS232 menu setting. I'm just looking for the right sequence to go either direction; obviously, I'll need to be connected on the right port to move control back And... I'll only test this when I'm local in the station! :-) Any help appreciated. 73, Gerry W1VE From brianchapnick at rogers.com Wed May 13 23:32:13 2020 From: brianchapnick at rogers.com (brianchapnick at rogers.com) Date: Wed, 13 May 2020 23:32:13 -0400 Subject: [Elecraft] Establishing A New Station In-Reply-To: <1743266389.462498.1589400638030@mail.yahoo.com> References: Message-ID: And how does the AX1 perform from inside your Apartment?

Interesting. I never make that assumption in em-comm. Having other people is handy, but each operator must be self-sufficient. Putting up the massive club station?

This is not an either/or situation. The stated purpose is what ARRL says it is. The incentive to participate, the icing on the cake, is a contest that is part of the event. You can get 950 points with zero QSOs. I?m assuming that the emergency power bonus does not apply if you don?t make any contacts. If it does, then you can score 1050.

Yeah, they've been saying that for years. Saying something doesn't make it true. For the vast majority of contesters of my generation, it was our first contest. It's a "gateway drug." And if you don't think it's a contest, you've never been part of a club that takes FD seriously. The club I participated with in Chicago was, and still is, one of the top three in its class, usually #1 or #2, and our current group in W6 has won 1AB three times. Important parts of doing well in FD are searching for and getting permission for a good site that is RF quiet and has good possibilities for rigging antennas, checking out all the gear in advance, selecting radios that play well together in a multi-transmitter environment (Elecraft is a big winner), rejecting those that don't (el-cheapo 160-440MHz for $1K junk), learning how to separate antennas to minimize interference between stations while maximizing performance, checking out every part of our stations in advance. There's a lot to be learned that prepares us for emergencies from every element of what I've outlined above. FD SHOULD also teach "short and sweet" operating procedures that are directly applicable for emergency operation -- that's when I first learned it from my contesting Elmer, W8FUM. 73, Jim K9YC From donwilh at embarqmail.com Thu May 14 14:46:23 2020 From: donwilh at embarqmail.com (Don Wilhelm) Date: Thu, 14 May 2020 14:46:23 -0400 Subject: [Elecraft] KX3/KX2 remote for FD In-Reply-To: References: <4A4BE0FF-F7DF-478A-81DC-F8A5C39EAE6F@arrl.net> <04D8C180-4FCA-4BA4-B748-8B220AB535E3@arrl.net> <064201d6296e$713bbc90$53b335b0$@LNAINC.com> <1589463704603-0.post@n2.nabble.com> <657b1354-b2bb-0500-ca82-5a9d6b3196ac@blomand.net> Message-ID: <15e54703-b6ab-d36c-508b-deb716484258@embarqmail.com> Yes Wayne, it was one of the greatest Field Days of all.

The adapters are available from Heil or can be easily put together yourself. I have always made my own. But first the KX3 in order to do PTT and provide clean audit you need to split a 3 stereo plug to 2 mono Jack's. One connected across the top and sleeve and the other across the ring and sleeve. I think Heil sells one, but I bought mine off of Amazon for about $5. I could hardly buy the connectors for that. There are many setting that need to be changed for the mic bias and button functions as well. But you end up with a nice headset when you are done.

I wrote the "Comm Plan" for each event for ICS. Now retired eleven years. IF you operate FD from home you can simulate some issues (like antenna down or no power). Or if allowed operating in remote locations try single-op mobile/portable. I have a home emergency generator so might simulate loss of power at home running 100w on 20m & 6m.

For instance, tuning changed significantly when I had mine laying on the roof vs. ~4ft above it (to the point where SWR was marginal on the lower part of 40m with the former). It was horizontal both times, too. Also, loops are going to have more loss at the lower end of their design range due to physics. 15w may very well not be enough to make contacts depending on how it's designed, though band conditions also play a role. -Mooneer K6AQ On Thu, May 14, 2020 at 7:21 PM Phil Kane wrote: > > On 5/13/2020 12:42 PM, brianchapnick at rogers.com wrote: > > > Im thinking of a loop.

I had joined the West Valley Amateur Radio Association because I felt I should support a repeater if I wanted to use repeaters as I traveled around the country and "west valley" was where my home was located. Well, the club is seriously into Field Day, with the goal of having as much fun as possible with as little work as possible. We try to qualify for all those 100 point items: emergency power, green power, GOTA, run a class, attract local pols etc. etc. Anyone who wants to get on the air will have a chance at operating, with a elmer if they need it. If you have a license, you can sit in one of the main operating positions. There is also a very active GOTA station for anyone who walks in off the trail that passes the location we use on Mora Hill. Well, that first field day, I had my arm twisted to try PSK on the digital station. I found that PSK was enough like the computer chat rooms which had been product of my company that I could relax and just operate. It was this experience which changed me from an equipment builder to an operator. (I still build equipment.) I moved from there into digital DXing. I caught the contest bug when I discovered I only needed a few QSOs for DXCC. One international DX contest pushed me over 100. I think that year we came in #4 nationally. We always treat the contest part of field day very seriously as well. It turns out that many club members are contesters and for them, a high score is part of having fun. And working with other people to set up a massive field day operation is fun too. Where we aren't particularly good is the food. We aren't permitted to have any kind of fire -- miles of dry grass all around our location -- so all food is brought up from homes or restaurants. So for me, the bottom line is: Lets go have fun. And big scores are a lot of fun. This year, it doesn't seem likely we will get a permit for Mora Hill. The general plan is to have everyone see what they can do by themselves. But, if lightning strikes and the permit comes through, we will see if we can do an operation with proper social distancing. BTW, one comment I have heard from my emcomm buddies is that although there haven't been any problems with normal communications (phones, internet etc.) some emcomm people have been asked to help because they are already familiar with ICS and working with non-ham emergency workers. 73 Bill AE6JV On 5/14/20 at 2:10 PM, jim at audiosystemsgroup.com (Jim Brown) wrote: >On 5/14/2020 7:56 AM, Bob McGraw K4TAX wrote: >>However it has become a "contest" to see who and what >>organization can accumulate the most points.?

I really like psk but seems there aren't many psk sigs on the band. Everyone has jumped to FT8. What are u Using? I run dm780 with HRD and a signal link. It is quite easy once you figure out how to set your level. You don't need signal link. Ive done it without the interface but with signal link its easier.

Where are the results posted? In the Contest section of the ARRL web site. How are they listed? By category and total score. Who manages FD? Those who manage ARRL contests? Are there rules like a contest? Yes. Do groups compete against other groups? Yes. Is there more to FD than making QSO's? Yes, somebody told me there was while I was searching through the results database. Is saying "Please copy." OK? Not if you want to make a lot of contacts. Is FD a great, wonderful, fun way to learn about contesting? Yes! Are the words "Not a contest." spoken in jest? Yes, a large percentage of the time. Is it fun to win a category? Oh yeah! Is it fun to come in 4th overall? Oh baby it is! Is it great to have all Elecraft gear at FD? No, it's a necessity to do well if you have more than one rig. I have been (unwillingly) to the Dark Side and prefer the ability to have three rigs on the same band, two of them on SSB, and not experience interference until moving to within 10 kHz. Will I miss competing with a group of friends? I certainly will! Will I still do FD? Is there anything else to do the fourth weekend of June? Will many individuals do it differently than last year? I hope so! Follow your State's Department of Health orders and stay healthy. This pandemic is real. It is not a contest that anyone should take stupid, unsafe steps to play. The listings are sad and we are nowhere close to beating this thing! And please stop whining about the spirit of FD. We're in the middle of a pandemic and you're worried about people making too many contacts or operating differently. Stay within FD rules, get on-the-air somehow, and make as many contacts as you can. If really necessary, enjoy some good food and drink, but not in mass gatherings however your State/County/City defines them. Stay healthy! HamVention 2021 is around the corner. Hopefully, I'll have my K4 before then. 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ From bobdehaney at gmx.net Fri May 15 09:45:43 2020 From: bobdehaney at gmx.net (Bob DeHaney) Date: Fri, 15 May 2020 15:45:43 +0200 Subject: [Elecraft] Field Day in Germany Message-ID: <001e01d62abf$214e5470$63eafd50$@gmx.net> Is definitely not a contest. Every club just decides with its members which weekend will be Field Day, not all clubs on the same day. Then we find a location, set up the antennas and one or two stations in tents and away we go, everyone taking time as an OP. This is usually accompanied by a Grill fest and of course in Bavaria, beer. Families are in and out and some camp overnight. So we do it in the Summer.

One caveat: They are resonant transformers and the loop MUST be exactly resonant at your QRG. This means, bypass any ATU and tune the loop [only] for 1:1 SWR. Using the "get it close and let the ATU match it" scheme will lead to a round, fairly pricey dummy load. > > 73, > Fred ["Skip"] K6DGW > Sparks NV DM09dn > Washoe County > > On 5/14/2020 7:19 PM, Phil Kane wrote: >> On 5/13/2020 12:42 PM, brianchapnick at rogers.com wrote: >> >>> Im thinking of a loop.

I haven?t heard directly from anyone at Elecraft since January 16 (and that after my instigation). Wayne and Eric have both periodically made multiple posts on this reflector updating progress on K4 manufacturing. Elecraft is based in northern California, where we are experiencing a pandemic, where anyone who can read and write has been sheltering in place for a couple of months, and working at home when their jobs permit. That's what's happening at Elecraft, and it's most likely true of the vendors who supply them parts, circuit boards, etc. My XYL and I live within 20 miles of their HQ, and haven't been in a public place since the first week of March. We go out only to walk for exercise in places where we can practice distancing and to make curbside pick-ups of food. 73, Jim K9YC From navydude1962 at yahoo.com Fri May 15 14:07:54 2020 From: navydude1962 at yahoo.com (Edward) Date: Fri, 15 May 2020 21:07:54 +0300 Subject: [Elecraft] KPA-500 Issues References: Message-ID: I have the combo K3S/KAT500/KPA500 with all of the optional interconnection cables.

We all knew that it was going to be months before it would be ready. And unless we were irretrievably daft, we all had to have known that delays were likely. There have been no secrets here. This was an investment in a future technology and we provided the venture capital. With the communications that occurred around the initial deposit, along with the occasional post on this reflector and the occasional newsletter giving updates on this product, they have been adequately transparent. There is no way in the world that a weekly update is necessary or practical. 73, David - N5DCH > On May 15, 2020, at 12:13 PM, David Gilbert wrote: > > > All of that is true, except that it doesn't take somebody like Wayne or Eric or any of their engineers to draft a weekly status report to those who have put down a deposit.

I haven't ordered a K4 and don't know if I ever will, but I'd be pretty upset to have put down that much money for ANY item with this little regular feedback on its shipping status since I can't think of a good excuse for it. From what I've seen, just about every status email from Elecraft has talked about K4 feature issues instead of when it might actually be delivered ... so no, I don't think that's being very transparent.

They are never prone to the blah blah updates of other companies but give out new or updated info when they have it, as always.? It's clear, concise, to the point and not redundant; refreshing for a company to provide it's customers; with minimal sales ego too. With most of the planet on hold, they're doing what can be done (with CA issuing one of the more Draconian mandates to it's subjects) and made it clear that they're as frustrated as you clearly are; they want to get back into the business of selling their products and helping customers.? They're also wise enough to know that no one can DEMAND information from suppliers; it's bad business and no one really knows yet, these waters are untested. Recap:? When they have something of merit to say, they will, as they always have. [Rumbles from knowledgeable sources have been heard in CA that the house arrest will continue there through Aug.? That likely puts shipping off for this year if/when Elecraft can ramp up at that time.? But NO ONE knows yet.] Suck it up, the rest of us are going through the same things with little to no whining.

The KAT4 ATU provides three SO-239 antenna jacks. Any of the three antennas can be selected for transmit. By extension, this becomes the default antenna for the receivers, unless you choose a different receive antenna. ATU LC settings for all three antennas are stored on a per-band basis, and each band can have up to 32 different stored segments. There are two receive antenna inputs, RX ANT in 1 and RX ANT in 2. In addition, either of the two KAT4 antennas *not* currently being used for transmit can be used as a receive antenna. In summary, each receiver has access to any of five antennas: - KAT4 ANT 1/2/3, either by sharing the TX antenna or by using one of the KAT4 non-transmit antennas - RX ANT IN 1 and 2 For internal transverters, there's a fourth SO-239 (or an N connector). This jack would be shared between two more transverter bands if applicable. 73, Wayne N6KR From nr4c at widomaker.com Fri May 15 15:38:22 2020 From: nr4c at widomaker.com (Nr4c) Date: Fri, 15 May 2020 15:38:22 -0400 Subject: [Elecraft] K4 TX Antenna port count and usage question In-Reply-To: References: Message-ID: I believe it?s 3 HF.

That said, I too would like more information and would think that merely having put a deposit down would mean you would get updates either on this forum or in the Elecraft Newsletter. I would like to know how much additional delay is likely for those in the EU as we must wait for CE approval before Elecraft can export to us. This is something like UL approval in the States. It is not a trade barrier but a safety certification. It would be interesting to know once manufacturing starts how long Elecraft estimate the time for CE approval to be granted. Of course there may be delays in this process due to Covid 19. I am happy to leave my deposit with Elecraft but then it does not affect putting food on the table. Again if you want you can get your money back but it would be really nice to hear more about plans, problems and improvements to firmware. It would also be good to be given specifications ala Sherwood Engineering but done by Elecraft. They must know what the K4 is achieving in its different configurations. Maybe this it tipping Elecraft's hand to the competition. We are all being cooped up and getting a bit anxious. At least we have something to look forward to. 73 Doug EI2CN -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of David Gilbert Sent: Friday 15 May 2020 18:13 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K4???

In fact, I'd bet that they demand it (even if speculative) from their suppliers. And Elecraft must have some idea how long it would take for them to restart assembly once they get parts and supplies. It seems like it would be possible to give a rough K4 delivery guestimate based upon that information even it is was subject to weekly or monthly change. As it stands now, people like W4KX don't have a clue whether they will get their K4 before the end of the year even if California opens up in June. That seems unreasonable to me for a $4,000 investment. > > You can spin this any way you want, but like I said, it doesn't require hand holding from anybody other than a clerk with access to Wayne or Eric to send out an update with an actual time frame associated with it. > > Dave AB7E > > > >> On 5/15/2020 11:25 AM, Rick NK7I wrote: >> Then here is your weekly status report: >> >> They're working on improving the firmware (notes posted to the reflector a couple DAYS ago made note of this). >> They're having (like much of the world) issues in getting hard dates for the bits and pieces to make more K4 (newsletter last month). >> When released from house arrest, they will be back at the job awaiting the parts they've ordered so they can build more (newsletter). >> When that is going to be, is anyone's guess for CA.

The original bandwidth is 30 Hz, which is good for code speeds up to about 30 WPM. The second bandwidth selection is 50 Hz, which allows copy up to about 50 WPM. On the air, I'm finding this a great addition to the receiver toolbox, especially for close-spaced, fast CW contests. Adjacent signals just seem to disappear. APF has a narrow bandwidth only for the first several dB from its peak, then flares wider below that. This can dramatically improve S/N for weak signals right at the noise floor: it brings up the signal without "boxing up" band noise into a very narrow bandwidth. That's what causes ringing with "brick wall" filters. 73, Wayne N6KR From alorona at sbcglobal.net Fri May 15 18:29:59 2020 From: alorona at sbcglobal.net (Al Lorona) Date: Fri, 15 May 2020 22:29:59 +0000 (UTC) Subject: [Elecraft] K4???

We do not want to see a resurgence of this virus. I need a haircut, and an appointment with my chiropractor, but those will have to wait because those are close physical contact situations. Since many of us are in the high risk category due to age, we must remain careful and vigilant even as things reopen. Facemasks and gloves are the order of the day for all outings as well as handwashing when we return home and hand sanitizer when not at home. It would be nice if all of this just went away, but that is wishful thinking during a major worldwide pandemic. The K4 will be ready when Elecraft can get the parts and start shipping. In the meantime, firmware updates and some Field Testing is all they can do. 73 and stay safe, Don W3FPR On 5/15/2020 6:29 PM, Al Lorona wrote: > Jim is right.

Here in the Bay area we are under control of the local authorities, who have things locked down much tighter than the rest of the state. The state folks are talking about starting to ease things over the next week. Here it will be at least a month. Take a look at the info at the Santa Clara County website for more info. Then realize that Silicon Valley is mostly inside Santa Clara County, and you will then start to see why getting things built and shipped from here is so difficult. We will get out of this, we just need patience. At least we are finally starting to be able to get toilet paper and rice. Flour is very difficult, though. It seems that everyone is baking? Masks? Forget it. We have to make our own. 73! Jack, W6FB > On May 15, 2020, at 3:29 PM, Al Lorona wrote: > > Jim is right.

In-Reply-To: References: Message-ID: Hi everyone, At Elecraft, like many of you, we are in our 9th week of shelter in place. This has been tough on all of us. Back on March 16th, when the initial California state and local orders were issued with an April 11 estimated end date, we suspected that it would last longer than that, but not as long as it this. The majority of our production team had to be furloughed immediately, with a few working from home. Most of our sales, support and the K4 engineering team have also been working from home. We allowed a minimal skeleton staff on site. ( Less than you can count on one hand, with each operating alone in large separate areas.). We've been able to ship a subset of our existing radios and accessories from finished goods stock, which has kept cash flow coming in. (We thank you for the continuing orders! ) We?ve also spent this time totally reorganizing our sales, operations, production and test areas for proper social distancing along with extreme cleaning and health screening procedures as per the new local and national COVID-19 guidelines for manufacturers. (Wearing masks at all times, Daily health screening upon entry to the building, additional spacing and partitions between work stations and ?you touch it, you clean it? procedures etc.) I?ll be posting links to some pictures of this in the next couple of days. This is a required change as per our local and State health departments. Many of our local sub-contractors (sheet metal fabrication, circuit board assembly etc) have also been impacted by shelter in place orders. Over the coming weeks, as the State and local health authorities slowly allow more activity, we should be able to get better delivery estimates from them as they are able to ramp back up. Like us, they are eager to get back on line. National and international parts suppliers have been similarly impacted. So what does this mean for first K4 shipments? Prior to the Covid-19 pandemic we were projecting first K4 deliveries beginning sometime in the April - May window this year. Obviously the pandemic has has thrown out those estimates. Based on a gradual reopening in California and other areas, our current feedback from suppliers, and taking into account unexpected delays, shortages, last minute engineering changes etc., my estimate is that first K4 shipments will begin somewhere in a window of late this July through the end of August. We?ll keep you informed as we get better information. As a side note, I?d like to thank everyone who has ordered a K4 for your support. We anticipated seeing cancellations during this pandemic delay, but we have received very few. Our K4 order backlog has actually continued to increase over the past 9 weeks. Wow! You, as our supporters and customers, have continued to energize and amaze us as we have created new products for you these past 21 years. Thank you. Also, as with all of our products, our engineering team keeps designing new features during the product?s lifetime. They certainly have not been idle on the K4 during the shelter in place order. (Our DSP S/W defined radio architecture allows us to continually give you a ?new? radio with each new sw release. :-) Keep an ear out for us on the air too. While making a few short test transmissions with my K4 this morning I ended up in a very nice QSO on 20M SSB! If you hear me, or others on our team, please say hello. We may be on a K4! We hope you, your family and friends stay well during this difficult time. 73, Eric elecraft.com _..._ > On May 15, 2020, at 3:55 PM, Don Wilhelm wrote: > > ?We here in North Carolina will be beginning to open after next Friday, but very carefully.

I use a small antenna analyzer to get it close and sometimes I have to adjust and step away from the antenna,take a reading and readjust I then follow up with adjustments with the radio connected for maximum band noise Also it needs to be a minimum of one diameter of the loop above ground,and more is better within reason. Is there a close ceiling that limits the height of the loop? Getting it in the clear is important,although with patience I?ve made contacts even indoors. Pick the bands carefully for propagation and as mentioned earlier tune for resonance. I?m strictly a QRP CW guy (5W Max) and have had good results by carefully adjusting to the surroundings and conditions. I have 2 loops-the AlexLoop and the W4OP. AlexLoop is good for 20 M and up while the W4OP is very efficient at 30,40 and 60 M. It?s very well made and an excellent design,although not the best option for backpacking as it?s a bit heavier.

I have a P3 as well, so can use the RS232 connection at the P3. An RS-232 "sniffer" (or Y cable) has been made and works OK. FA, FB and IF words coming from the K3s can been seen when I start Wintest or my home-made FA/FB-generator.exe. I can also decode those (frequency) words correctly with an Arduino (which is used to slave an FT847 to the K3). So the Y cable works OK and frequency information is present. The Y cable is connected to the SDA 100 Data IN, radio port, points 2 (RXD) and 5 (ground) SDA 100 setting is : Mode : Kenwood (in accordance with SteppIR instructions) Din 19200 Dout 19200 Baud rate both P3 and Wintest = 19200 No Autotracking of the SteppIR occurs, changing baud rates makes no difference. The RS232 convertor inside the SDA100 works OK. The MAX202 converts the data at RS232 level correctly to 0- 5V levels. I am a bit out of options. Anyone who can point me in the right direction? 73 Henk PA0C -- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. https://www.avast.com/antivirus From mike at ve3yf.com Sat May 16 06:11:31 2020 From: mike at ve3yf.com (Mike VE3YF) Date: Sat, 16 May 2020 10:11:31 +0000 Subject: [Elecraft] K4???

If it's a K4, then you've probably just seen the latest estimated lead lead times and they're for those that already have firm orders placed. They do seem to have stock of 'other' radios, which they're currently shipping. One thing I do know about Elecraft is if you put money on the table and something goes wrong (such as a pandemic they will do the honorable thing, so you'll either get a refund or the goods. Other companies are not so customer orientated and a few will actually steal from you. If Elecraft can't supply (say) a K3S, you could consider the used market, then when the K4 finally ships, you could either sell the K3S for more-or-less what you paid for it or if you're 'well heeled' you could just keep it as a standby rig. I'm in the UK, so it doesn't particularly matter to me which country my rigs come from and shipping is about the same, but a) I can't buy direct from any other company. b) When I'm in trouble, I don't have direct access to the owners of the other companies, in fact direct access to any of the staff of other companies is next to zero. c) Elecraft support is second to none. Direct support from other companies is often mediocre to zero. d) I don't know about other company's staff as I never get to speak to them, but Elecraft are such a nice bunch of people!

At that time, I believe they anticipated the ship date to be in time for the 2019 holidays. Then, the testers found some things that needed correcting, which pushed the ship date out a couple of months. Then, COVID-19 hit, we all went into shelter-in-place, Elecraft had issues getting parts, and the work slowed down. And Eric and Wayne have been up front about explaining all this to us. But, the key here is that this transceiver is ground-breaking new technology. It is a brand-new product still under development, a process that was delayed largely due to world events beyond anyone's control. There were similar delays (save for the global pandemic :-) ) and similar complaints when the KX3 was released several years ago. A new product will not always meet the time lines the developers initially anticipate and announce. But, Eric and Wayne have said repeatedly in this forum, and in the newsletter, that they have product in their other lines available to ship. If you are concerned about your order, please email sales at elecraft.com. The wonderful sales team will tell you what's in stock and what isn't. While I haven't ordered anything during the current pandemic, I have never had a problem with product I ordered being out of stock or back-ordered. But, the long and the short here is that I wouldn't be concerned about product availability. Pay attention to the K4 conversation, but take it with a grain of salt, especially in these unique times. As someone else posted here earlier, I'm waiting for the K4 kit to come out before I order mine (probably a K4-HD). I also know it will probably be at least another year before the kit versions become available. But, I can wait. In the meantime, I finally have some time to really get to know the KX2 I've had for nearly 18 months, and I will continue enjoying my K3-based K-Line (K3, P3, KAT500, KPA500). 73 de, Ian, NV4C On 5/16/20 6:56 AM, Tommy Judson via Elecraft wrote: > Good Morning > > I?ve been studying how to establish a ham station and asking around what is available to do that with these days.

If I had an antenna up, an itch to get on the air, and was just waiting for a rig, I would not wait for a K4. You might consider the KX3 line. If you are still OK with a soldering iron and like to build things, maybe a K2, but if not, well I hear nothing but good things about the KX3. Even if they are out of stock, you?d get these much sooner than a K4. You can also go out on the used market and probably find a K3 or K3S. I used to have a K3 and it was the finest rig I?ve ever owned to date. Be warned, there is a learning curve associated with Elecraft rigs, but in my experience, its *absolutely worth it*. In my case, I invested in a K4 around this time last year (knowing it wasn?t going to be ready right away), then picked up an inexpensive rig for use in the meantime just to get me on the air while I wait for my K4. 73, David - N5DCH > On May 16, 2020, at 4:56 AM, Tommy Judson via Elecraft wrote: > > > Good Morning > > I?ve been studying how to establish a ham station and asking around what is available to do that with these days.

Found: My Flex-6600 settings had somehow changed (I didn't do it, honest!) to disable the PA Key line for all bands (!), in a menu matrix I didn't even know existed. I've corrected these settings, and all is well. True to my "bonehead" title, I should have done some basic troubleshooting before posting. But I was so sure that I had nuked the KPA500 input, I didn't look in other places. It's good to know you're there, willing to help. 73, --jim KJ3P -----Original Message----- From: Jack Brindle Sent: Friday, May 15, 2020 6:58 PM To: Jim Perry Subject: Re: [Elecraft] KPA500: Bonehead Input Overload Jim; Sorry to hear you are having troubles with your KPA500. I am sure the guys in Support are backed up, so let?s see if I might be able to help. My questions: * How does the receive sound with the amplifier in STBY? OPER? Does it drop, or sound as expected with the KPA bypassed? * While in STBY, when you transmit, are there any issues with the output, is it attenuated? * Are you getting the normal asterisk in the LCD when you transmit with the KPA in OPER? You don?t mention which transceiver you are using, but I?d like to test the RF band switching. If you normally have RADIO = K3 or BCD, change to RADIO = SERIAL. if normally RADIO = SERIAL, change to RADIO = BCD You get the idea - change RADIO to something besides normal (but not BCD if a K3). Then, with the KPA in STBY, change bands on the TX and transmit, does the KPA also change bands? Lastly, if you will send me a KPA500 fault log, I will analyze it. Use the KPA Utility, go to the Configuration tab. Select ?Display Fault Table?. Click on Save to File, then send me the resulting file. Hopefully we will be able to fix things without sending your baby back to Watsonville. 73!

Sometime ago due to probably high SWR (water in the Pl259 leading to KAT-500) the KPA-500 stopped after a loud noise (can't tell whether KPA or KAT) was heard. When I reset it & checked all bands into a dummy load (no tuner), It delivered half the regular output power on all bands. (25w in for appx. 150w out). I don't know if this means 1 side of the PA is gone, or is there some 3db pad connected permanently. Any ideas for test procedures? Also how safe (forbidden?) is it to operate the amp in this "half-power" condition?

I have two identical K Line stations, K3's, KAT 500's, KPA 500's and P3's. On station #1 everything works as it should and if I put 25 watts into the KPA 500 I get 500+ watts out. On station #2 if I put 30 watts into the KPA 500 I get 350 out and if I increase the input to 32 watts the KPA 500 momentarily shows 400 watts out and immediately trips the amp and shows the PA DISS fault. It works fine on all other bands putting out 500 watts with nominal drive power. If I then swop the KPA 500's over without changing any antennas or radio settings (so nothing except the amps has changed), the fault moves with the amp and the good amp continues to be good on the other station. My questions: What is wrong with the faulty amp and what do I need to do to fix it? Many thanks for reading. Mike, WM5DX.

I have a Bird with various slugs and dummy load but I would not assume it was even close to the accuracy that Elecraft achieve even if I had just had it calibrated the day before. From memory the Bird is *only* 5% accurate on the day of calibration, whereas a modern lab quality digital power meter must surely be far better, perhaps in the 1% region. So, I'm questioning the need to change the factory settings. While on this topic, I'm curious to know how long the factory settings last and to what accuracy.

(Scope shows no indication of polling when Ser Poll is on.) KPA500 has an IO board with two serial interfaces. One is for connection to a PC and the other for connection to a transceiver. The data out line of the XCVR port passes through relay K1 and I assumed this relay would be open when SER POLL is set to OFF. My scope measurements show this line is actually pulled low when SER POLL is Off which implies that K1 is not open. With Ser Poll On I see normal polling with IF;FA;FB; My interface works ok although I'm currently using the PC port not the XCVR for KPA500 control. I suspect that Jack is the only one who will know the details but I'm asking here so others can learn if interested. My question is: Serial IO board K1 is controlled by "SBYB" which traces to signal "BYPRLY". The names suggest "bypass relay" but under what circumstances is this signal set/cleared? In other words, when does K1 open the data out line?

No change. I finally pulled them out and only used the keying cable (RCA to RCA). No change. One thing I noticed is that the KAT 500 was giving me Power and SWR reading, but no amplification from the amplifier. And if I had any more than 12w of drive power from the K3, the amp would not give me any reading at all. Dropping it back to under 12w, the Pwr/SWR readings would be visible again. I decided to disconnect the antenna from the KAT 500 altogether and connected straight into the amp. Low and behold, I now have the amp working again! Hence, the problem is with the KAT500 tuner. I am thinking that a factory reset would do the trick. Question is, how do you reset a KAT 500 to factory default? The manual states to do it with a computer. Any buttons I can push on the tuner itself for restoring the factory defaults?

My station is set up exactly as described by Andy below. Also, the K3 is set to remember output power by band. KAT500 hancles disabling the amp on SWR faults and when tuning (rarely done as Ive taught it my antennas), it will inhibit the KPA500 until the SWR issue is corrected. The KPA500 also communicates with the radio. When it trips or turns off for any reason, it will talk to the K3 and tells it it went offline. It also screams at me to call attention to the issue and the K3 beeps in my headset and flashes a crawl message on its screen to tell me the amp is offline. I have fewer communications between the amp and the tuner with my TS590. On an SWR fault or tuning, the KAT500 keeps the amp in standby until it is happy with the SWR (in my case, below 2:1). Sometimes when changing bands with the '590, it takes a microsecond more to have the KAT500 figure out where the rig QSY'd to, so it keeps the amp offline until it figures things out. In this case, I need to manually re-enable the KPA500 for any reason. Ive also boneheadely transmitted the TS590 at 100w with the amp enabled. The amp IMMEDIATELY goes to standby and screeches loudly at me.

Enabling conditions include Hi_SWR false and TS-590 power set and verified. Set drive power is not allowed to exceed 120% of band max drive power.

"Ive also boneheadely transmitted the TS590 at 100w with the amp enabled. The amp IMMEDIATELY goes to standby and screeches loudly at me." A clear indication that your setup is not exactly like mine. My controller won't let me TX at 100 W with the KPA500 in OPER and the key line enabled. I described my protection as follows - "In my station the KAT500 is commanded to inhibit the KPA500 key line by default. Only when all required conditions are met is the key line enabled." I think you will find the KAT500 works exactly opposite to that. It keeps the key line enabled unless it detects a reason to inhibit it. I don't even rely of the KAT500 controlling the key line during Autotune because it re-enables the line too quickly which results in a large power spike. (The power spike is probably short enough that most people wouldn't notice it but it's easily seen on a scope and my LP-100A in peak mode). 73, Andy, k3wyc From kl7uw at acsalaska.net Sat May 16 16:39:57 2020 From: kl7uw at acsalaska.net (Edward R Cole) Date: Sat, 16 May 2020 12:39:57 -0800 Subject: [Elecraft] (no subject) Message-ID: <202005162039.04GKdvgd014440@mail46c28.carrierzone.com> Just read the KX3 (with upgraded firmware) does 15w output, so 31.6* x 15w = 474w from a KPA500; *15-dB.

While St Kitts might have been better, Laguna is more than good enough. The biggest challenge with my dual KXPX3/KXPA100 is the tom of connecting wires/cables especially when a 2x6 antenna switch and BPFs are included. This prompts a quick follow up question which apologies ahead of time if it?s a well discussed topic. Can the second K4 receiver, with appropriate filtering etc listen to a different band continuously while I am calling on another? The use case isn?t very sophisticated and is simply searching for mults on one band while calling on another. I think with the K3s sub receiver that it is disconnected from any antennas while transmitting. So the gist of my question is whether the K4 second receiver is disconnected from an antenna when one of the other HF antenna ports is used to transmit.

While St Kitts might have been better, Laguna is more than good enough. The biggest challenge with my dual KXPX3/KXPA100 is the tom of connecting wires/cables especially when a 2x6 antenna switch and BPFs are included. This prompts a quick follow up question which apologies ahead of time if it?s a well discussed topic. Can the second K4 receiver, with appropriate filtering etc listen to a different band continuously while I am calling on another? The use case isn?t very sophisticated and is simply searching for mults on one band while calling on another. I think with the K3s sub receiver that it is disconnected from any antennas while transmitting. So the gist of my question is whether the K4 second receiver is disconnected from an antenna when one of the other HF antenna ports is used to transmit.

Major NTP servers like time.nist.gov are the most accurate clocks, but they aren't meant for everyone to use -- that's just too much traffic and latency hurts their accuracy if they're abused.

It actually controls the gain of the 8.215 MHz IF amplifier immediately following the 8.215 MHz roofing filters which then controls the 8.215 MHz IF signal level feeding the 2nd mixer. See the K3 RF Board schematic, page 4 of 4. The 8.215 MHz IF amplifier is Q1. IF amplifier gain is controlled the front panel "RF Gain" control (labelled as VIF Gain on the schematic) via U3. This is why its so critically important to select the correct Preamp setting (Preamp1, Preamp2 (in the K3S) or OFF) and proper attenuation level because those are the only gain controls in the RF path of the K3/K3S. If you select Prramp or attenuation incorrectly you've inserted excessive signal levels into the roofing filters and IF amplifier. 73 Frank W3LPL ----- Original Message ----- From: "John Reilly" To: Elecraft at mailman.qth.net Sent: Sunday, May 17, 2020 9:40:06 PM Subject: [Elecraft] [K3/K3s] RF Gain Control Where in the K3/K3s Block Diagram is the RF Gain control located?

The names suggest "bypass relay" but under what circumstances is this signal set/cleared? In other words, when does K1 open the data out line?" Well I found the answer thanks to another KPA500 owner running a similar test. It turns out that setting SER POLL to OFF and remaining in the Menu stops polling but leaves the relay closed with -12 V on pin 3. Only when the menu is exited does the relay get deactivated and pin 3 goes open circuit. Similarly, opening the menu and setting SER POLL from Off to On leaves the relay open and the relay only closes when the menu is exited. I wonder how many KPA500 owners have been caught by this. 73, Andy k3wyc From rmcgraw at blomand.net Sun May 17 20:11:02 2020 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Sun, 17 May 2020 19:11:02 -0500 Subject: [Elecraft] [K3/K3s] RF Gain Control In-Reply-To: <351204302.6517668.1589754493141.JavaMail.root@starpower.net> References: <351204302.6517668.1589754493141.JavaMail.root@starpower.net> Message-ID: <3DAEDD37-A736-45F8-A0AF-99865BB48317@blomand.net> In all instances, 160M, 80M, & 40M, I run 15 dB Attenuation.

For reference, my station consists of a TS-890 followed by a KPA-500 and a KAT-500, that interfaces different wire antennas depending on the operating band. One Friday night after dinner, I headed to the ham shack to check out 160M. Since it had been raining I needed to check the antenna SWR. After completing a KAT-500 (KAT) tuning cycle at low power, I had a new tuning solution and switched in the KPA-500 (KPA) for confirmation. I started at low power and slowly increased the power level. At around 100 watts output from the KPA I was rewarded with what I call the ?Allen-Bradley? smell, a slight cloud of smoke and a KPA low voltage alarm! I immediately cut power and tried to reset the KPA alarm but couldn?t by cycling the power off/on. So I unplugged the KPA from the AC power. After reconnecting the power and turning the KPA on, the alarm was gone. I repeated the tuning process, with almost the same results except the smell and smoke were more noticeable. At this point I took the KPA completely off line, disconnecting all control and RF connections, and raised the power out level of the TS-890 to 90 watts, which then confirmed normal operation via the KAT. At this point I began to think about returning the KPA for repair and wondered how long it would take to get it back, considering COVID-19 issues. For some reason I decided to try the KPA500 - KAT500 pair one more time. This time I moved closer to the KPA500 to try to get a clearer idea of where the ?smoke? was coming from. I slowly raised the power one more time and the KPA shut down just like before, but this time I noticed the ?smoke? was coming from what looked like the rear of the amp. I moved the KPA and noticed the smell was still very strong - and at the rear of the KPA. It was then I noticed that the AC line surge suppressor the KPA was plugged into, in a wall socket directly below the back of the operating table with the KPA, was the source of both the smell and ?smoke?. I bypassed the suppressor and was relieved when the KPA returned to normal operation. Somehow, when the current draw through the suppressor reached a certain level, failing internal suppressor component(s) overheated and presented a line voltage drop to the KPA500 sufficient to trigger the internal low operating voltage alarm. With the suppressor located directly behind and below the KPA, it seemed like the smell and smoke were coming from the KPA - and the KPA was failing since the KPA low voltage alarm activated. So of course, always check to make sure the equipment you?re troubleshooting is actually ?plugged-in? (following troubleshooting safety guidelines) - but also check to make sure any in-line power surge suppressors are working correctly. 73, Bob, W3RW From n6kr at elecraft.com Mon May 18 12:12:47 2020 From: n6kr at elecraft.com (Wayne Burdick) Date: Mon, 18 May 2020 09:12:47 -0700 Subject: [Elecraft] K4 Kit???

It does take longer to get the kit version out since many new drawings are required to accurately communicate details on modules, cables, and hardware to builders (as opposed to in-house assembly personnel). Can't really put a date on the kit version at this time, but it will be well after we begin shipping the K4 and K4D. There's an intermediate approach that many of our customers have used over the years: get an assembled basic radio, then install option modules yourself as required and as time/availability permits. Option modules will come with detailed assembly instructions. 73, Wayne N6KR > On May 17, 2020, at 2:14 PM, Charlie T wrote: > > Yep, just more fun to "build" one eh? > > Actually, I'm just plain "Cheap" and hoping to save a few bucks on a kit > version. > However, recent Elecraft kits are more like erector sets, but I DID build a > K2 complete with soldering stuff. > > 73, Charlie k3ICH > > > > > -----Original Message----- > From: elecraft-bounces at mailman.qth.net On > Behalf Of Steve KC6ZKT > Sent: Sunday, May 17, 2020 4:34 PM > To: elecraft at mailman.qth.net > Subject: Re: [Elecraft] K4 Kit??? > > On 5/15/20 8:08 PM, Bill Frantz wrote: >> And I'm still waiting for the kit version. > Same here.

On either USB or LSB there is a significant, narrow signal spike which tracks the KX3 frequency. On either USB or LSB it is at the edge of the cursor where the carrier (suppressed) would be. There is no tone as I tune across it and it does not interfere with operation. The waterfall does show a narrow trail. If I change the XFIL from FL1 to FL2 then the spike moves to the center of the new, narrower passband. On CW it is in the middle of the passband.

What a relief to hear the actual cause ... and I can well imagine it was doubly so for you! 73 Lyn, W0LEN -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bob Witmer Sent: Sunday, May 17, 2020 11:31 PM To: Elecraft at mailman.qth.net Subject: [Elecraft] An Unusual KPA-500 Failure - That Wasn?t ... I thought the group might find a recent KPA-500 troubleshooting experience interesting - and possibly be of help with future troubleshooting efforts. For reference, my station consists of a TS-890 followed by a KPA-500 and a KAT-500, that interfaces different wire antennas depending on the operating band. One Friday night after dinner, I headed to the ham shack to check out 160M. Since it had been raining I needed to check the antenna SWR. After completing a KAT-500 (KAT) tuning cycle at low power, I had a new tuning solution and switched in the KPA-500 (KPA) for confirmation. I started at low power and slowly increased the power level. At around 100 watts output from the KPA I was rewarded with what I call the ?Allen-Bradley? smell, a slight cloud of smoke and a KPA low voltage alarm! I immediately cut power and tried to reset the KPA alarm but couldn?t by cycling the power off/on. So I unplugged the KPA from the AC power. After reconnecting the power and turning the KPA on, the alarm was gone. I repeated the tuning process, with almost the same results except the smell and smoke were more noticeable. At this point I took the KPA completely off line, disconnecting all control and RF connections, and raised the power out level of the TS-890 to 90 watts, which then confirmed normal operation via the KAT. At this point I began to think about returning the KPA for repair and wondered how long it would take to get it back, considering COVID-19 issues. For some reason I decided to try the KPA500 - KAT500 pair one more time. This time I moved closer to the KPA500 to try to get a clearer idea of where the ?smoke? was coming from. I slowly raised the power one more time and the KPA shut down just like before, but this time I noticed the ?smoke? was coming from what looked like the rear of the amp. I moved the KPA and noticed the smell was still very strong - and at the rear of the KPA. It was then I noticed that the AC line surge suppressor the KPA was plugged into, in a wall socket directly below the back of the operating table with the KPA, was the source of both the smell and ?smoke?. I bypassed the suppressor and was relieved when the KPA returned to normal operation. Somehow, when the current draw through the suppressor reached a certain level, failing internal suppressor component(s) overheated and presented a line voltage drop to the KPA500 sufficient to trigger the internal low operating voltage alarm. With the suppressor located directly behind and below the KPA, it seemed like the smell and smoke were coming from the KPA - and the KPA was failing since the KPA low voltage alarm activated. So of course, always check to make sure the equipment you?re troubleshooting is actually ?plugged-in? (following troubleshooting safety guidelines) - but also check to make sure any in-line power surge suppressors are working correctly. 73, Bob, W3RW ______________________________________________________________ From rmcgraw at blomand.net Mon May 18 13:22:10 2020 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Mon, 18 May 2020 12:22:10 -0500 Subject: [Elecraft] =?utf-8?q?An_Unusual_KPA-500_Failure_-_That_Wasn?= =?utf-8?b?4oCZdCAuLi4=?= In-Reply-To: <009a01d62d37$ea998870$bfcc9950$@LNAINC.com> References: <6651E96B-EDD4-434F-939B-888D6DDDA306@gmail.com> <009a01d62d37$ea998870$bfcc9950$@LNAINC.com> Message-ID: <6ddd23ae-8633-974a-3f48-a2639c24482f@blomand.net> I have installed a whole house surge protector on the main breaker panel. ?

Some will be, including the KAT4, KPA4, and KRX4 (the latter is what turns a K4 into a K4D). But customer-installation docs take some extra time. Our documenters are busy as beavers working on the owner's manual. (I don't mean chewing it, though a printed copy would be a good source of fiber.)

After completing a KAT-500 (KAT) tuning cycle at low power, I had a new tuning solution and switched in the KPA-500 (KPA) for confirmation. I started at low power and slowly increased the power level. At around 100 watts output from the KPA I was rewarded with what I call the ?Allen-Bradley? smell, a slight cloud of smoke and a KPA low voltage alarm! I immediately cut power and tried to reset the KPA alarm but couldn?t by cycling the power off/on. So I unplugged the KPA from the AC power. After reconnecting the power and turning the KPA on, the alarm was gone. I repeated the tuning process, with almost the same results except the smell and smoke were more noticeable. At this point I took the KPA completely off line, disconnecting all control and RF connections, and raised the power out level of the TS-890 to 90 watts, which then confirmed normal operation via the KAT. At this point I began to think about returning the KPA for repair and wondered how long it would take to get it back, considering COVID-19 issues. > > For some reason I decided to try the KPA500 - KAT500 pair one more time. This time I moved closer to the KPA500 to try to get a clearer idea of where the ?smoke? was coming from. I slowly raised the power one more time and the KPA shut down just like before, but this time I noticed the ?smoke? was coming from what looked like the rear of the amp. I moved the KPA and noticed the smell was still very strong - and at the rear of the KPA. It was then I noticed that the AC line surge suppressor the KPA was plugged into, in a wall socket directly below the back of the operating table with the KPA, was the source of both the smell and ?smoke?. I bypassed the suppressor and was relieved when the KPA returned to normal operation. > > Somehow, when the current draw through the suppressor reached a certain level, failing internal suppressor component(s) overheated and presented a line voltage drop to the KPA500 sufficient to trigger the internal low operating voltage alarm. With the suppressor located directly behind and below the KPA, it seemed like the smell and smoke were coming from the KPA - and the KPA was failing since the KPA low voltage alarm activated. > > So of course, always check to make sure the equipment you?re troubleshooting is actually ?plugged-in?

Do others report RFI problems? Josh, Bob, and all, I have no experience with Astron SMPS, and have seen nothing. I do, however, own several no-name switchers advertised as quiet that are quite noisy. My question was techie-rhetorical. We should not trust ANY reports that xxx product is RF quiet unless we know a LOT about proximity of noise source to antennas, the sum all of the other noise that could be obscuring it in the observer's receiver, and that info for ALL ham bands. A meaningful test would be waterfall plots from an SDR with a small loop antenna that can be placed in proximity to the potential noise source. This doesn't require lab-quality testing, simply a waterfall covering the frequency range of interest. Prior to the availability of inexpensive SDR RX, I've used (and still do for some applications) the broad coverage RX in my VHF/UHF talkie. 73, Jim K9YC From pubx1 at af2z.net Mon May 18 17:17:11 2020 From: pubx1 at af2z.net (Drew AF2Z) Date: Mon, 18 May 2020 17:17:11 -0400 Subject: [Elecraft] K4 Kit???

About the same? More? Less? (More parts = more fun.) Hi Drew, Rather than a parts count -- an esoteric parameter I get paid to worry about -- I'll give you a qualitative breakdown. Even a basic K4 is the equivalent of: K3S + P3 + KRX3 (for dual-watch purposes) + KXV3 + KDVR3 + Linux/Intel MPU + large touch screen + external monitor adapter (like P3 SVGA, but HDMI) + more controls, more antenna jacks, more digital I/O ports, and all the DSP/ADC/DAC/FPGA hardware needed to create a modern SDR. It also has a multi-processor architecture with unlimited potential for future expansion. Of course there are economies related to it being an SDR, such as no crystal filters in the basic unit. From this you could take an educated guess. 73, Wayne N6KR > > 73, > Drew > AF2Z > > > On 05/18/20 11:12, Wayne Burdick wrote: >> We certainly appreciate the interest in a K4 kit.

If the SteppIR controller is connected in parallel with a computer the TxD line *must not be* connected as it will load the TxD output of the computer and *neither* device will be able to poll the transceiver. The appropriate schematic would be for the SteppIR "Y" cable: > Is that connection needed? If it is connected, might it obviate the > need for a separate CAT program? There are some (diode matrix or logic based) devices that will allow two "controllers" to share a single RS-232 controlled device but they are not easy to find/build. An easier device (if your logger can set DTR high when running) might be a simple relay to switch the TxD line between computer and SteppIR depending on whether the logger is running (and polling the transceiver). 73, ...

(could be at the P3 as well) A separate CAT/logger program is not needed to invoke K3(s) info to be send Using the K3(s) Auto Info setting in the Config menu assures that the K3(s) sends frequency info each time the VFO is changed. The SDA 100 follows this without a glitch. Btw : I made a small .exe that invokes the K3(s) to send FA, FB and IF words on a regular basis. This could replace any (expensive or memory eating) logging program in case you want to be absolutely sure all K3 frequency info is being send/decoded. I use it for tracking purposes of my home made remote controlled PA, which cannot afford to miss K3 info. However it could be used with a K3/SDA100 combo as well. 73 Henk PA0C -----Oorspronkelijk bericht----- Van: elecraft-bounces at mailman.qth.net Namens Lou W0FK Verzonden: dinsdag 19 mei 2020 15:21 Aan: elecraft at mailman.qth.net Onderwerp: Re: [Elecraft] K3(s) SteppIR control The "official" SteppIR cable schematic also shows that Pin 3 (TXD out on the K3S's RD232 DE9) is also to be connected. https://groups.io/g/steppir/files/Controller%20Cable%20Schematics/S-26_21-60 26-01%20Cable,%209%20pin%20FM%20to%20Male%202%203%205.pdf Is that connection needed?

On a TS-590S COM port pin 2 is designated "RXD" and is the data output. COM port pin 3 is designated TXD" and is the data input. I would expect K3 pin designations to be the same. As has been pointed out - two RS-232 transmitters should not be connected together. Multiple RS-232 receivers can usually be wired to one RS-232 transmitter.

So wait a bit when you test this! Also, Try the PH.R + -- in the other setting and then test the above again, waiting for the delay. **In ANY case; *IF* you do in fact have rear SPKRS jack audio, and you unplug them, the internal speaker should come on! If not, there is most likely a physical problem, like bad speaker/wire/spkr jack etc. The internal speaker gets it's audio directly from J18 (rear spkrs) jack thru L3 (could be open) on the KIO3B Audio board. An aside, if anyone is searching audio problems; If you have had the Front Panel off, I have seen the J/P50 plug on the DSP to RF board *UP* a row of pins! This totally fubars up all the rear audio!!

I have double checked the values of components on the filter board to ensure they are correct and installed correctly. I also checked T3 and T4 which can cause issues on 40. T3 has 23 turns on the secondary with three turns on the primary. T4 has 24 turns on secondary and two turns on primary. Another symptom is the CH trimmer cap seems to be at one end of tuning range (not seeing double peak). Note - the radio does not have the ATU option and 30 meters is set for 10.1 MHz and not 10.0 (double checked crystals). >From what I can measure so far the relays seem to be working "as designed".

I did notice in the 4 band filter manual it says K6 relay is not active on 40 but I do see it active and looking at the schematic K6 switches between 15/20 operation and 30/40 so I think there is a typo in the filter board manual at the bottom of page 23. I am using a Marconi service monitor for testing. I have not built an RF probe yet and hoping someone has seen this symptom before.

They MUST be done in the proper band sequence - 30 meters before 40m, 15m before 20m.

I want to know what load is being presented to the KPA500. Neither the KPA500 not the KAT500 can display complex load values. Since the LP-500 and LP-700 are intended to sample amplifier RF input and amplifier RF output I would expect the amplifier output sampling to be performed before the tuner.

This allows easy swapping from exciter output to amplifier output with a button press, and allows amplifier linearity monitoring using the LP700.

I understand 40 is a combo of 30 & 40 settings. After carefully retuning (done it several times) the best I can get on 40 is about 60 to 75 mW. 30 makes better than 2 watts. The menu for power out is set to 2.0 on 40. Receive sensitivity is 10 to 15 dB down from 30 meter receive. I read that the windings on T3 and T4 are critical. I have counted the turns and verified which side #1,2,3 and 4 are coming off the core. Both T3 and T4 appear to be fine. There is enough wire left over in the box the radio was in so I can rewind T3 or T4. From what I see on the schematic T4 would most likely be the suspect (if it is the transformer.) I am going to borrow an RF Power meter with probe and check 30 vs 40 meter readings on the Premix in & out and the RF filter in & out. That will greatly help pinpoint the issue. 73 Dave wo2x -----Original Message----- From: Don Wilhelm Sent: Wednesday, May 20, 2020 11:39 AM To: rocketnj at gmail.com; elecraft at mailman.qth.net Subject: Re: [Elecraft] K1-4 low power and poor receive on 40 meters Dave, Refer to the K1FL4 instructions and re-tune the trimmers on the filter board.

In-Reply-To: References: Message-ID: The KAT500 (and utility) can show the values used by the tuner to match the 50 ohm impedance of the radio.? Similar is possible either via the KPA1500 utility or the front panel of the KPA1500. While it doesn't show the complex load; it gives enough to begin to figure out what the antenna is presenting (for use in apps like WinSmith etc) so one can make intelligent changes in the antenna. I've used the utility for monitoring (and remote control) of the KPA500/KAT500 combo for years; now I'm using the KPA1500 utility for the same reason. The KPA1500 presents a lot more useful information on the front panel (click on the menu button then the down triangle to select the menu you want).? Because my antennas are resonant, I park the amp display at power out, efficiency, volts and amps used and temp.? The power out on the utility also shows the reflected power in watts, nice to know. If you put the LP sensor between the amp and the (not resonant) antenna, any mismatch will likely give you erroneous readings that would offer no value.? It would compare the antenna value (say 150 ohms of mixed reactance/resistance) to the tuner value (whatever is required to match to 50 ohms).? The worse the unmatched condition, the more useless the display becomes.? It wants to see 50 ohm in, 50 ohm out to provide accurate power readings. So if your antennas demand a matching circuit (tuner), the LP sensor becomes less valued at the output of the amp. 73, Rick NK7I On 5/20/2020 9:41 AM, Andy Durbin wrote: > "If it were mine, I would put the LP700 on the antenna line to monitor what is going on with the antenna itself." > > My LP-100A is between my KPA500 and my KAT500. I want to know what load is being presented to the KPA500. Neither the KPA500 not the KAT500 can display complex load values. Since the LP-500 and LP-700 are intended to sample amplifier RF input and amplifier RF output I would expect the amplifier output sampling to be performed before the tuner.

In-Reply-To: References: Message-ID: I tend to agree. With the right calculations, the reported power, SWR and matching inductors and capacitors from the KPA1500 will tell you more about the antenna. In addition, the KPA1500 already has a monitoring port that could be used for an output modulation / spectrum monitor. Of course, something like that would have to be built that took those inputs. I expect a K4 will do it! The KPA500 does get calibrated at the factory for power, SWR, etc, probably against decent, calibrated test equipment. I'll bet it is designed to hold some sort of calibration over time. Hams tend to treat uncalibrated test gear as gospel. An external power meter, just because it reports to the nearest 0.1W isn't necessarily better. Any commercial operation calibrates on a regular cycle. Being a slightly less cheap Ham than most, I do get one scope / spectrum analyzer calibrated every year, so at least I have something to compare the other stuff to. Does the KPA500 report the tuner topology (if it is even switchable)? Is it an L match? Does it report which element is the shunt element? Does a specific L and C and shunt element match only one unique load? The other issue is that the Ls and Cs reported are probably 20% or more off, so the calculation would not be perfect. The C and L ladders are not even guaranteed monotonic, so a reported LC combination may be off. Tuners often try the next one higher and lower. I did measurements of an LDG tuner and the inductance jumped up and down. Step N-1 was not necessarily less inductance than step N. Two steps generally got in the right direction. 73, Mark W7MLG On Wed, May 20, 2020 at 12:07 PM Rick NK7I wrote: > The KAT500 (and utility) can show the values used by the tuner to match > the 50 ohm impedance of the radio.

So I will throw this out to the group. It appears that there is an error in the KRC2 manual and it is not shown in the Errata sheet. On page 24 the manual states the following when connecting the KRC2 to an Icom radio: "For this reason it is recommended that the reference input setup be used. In this configuration, the band data is connected to pin 9 and the 8 volt reference is connected to pin 4. This mode is set with jumpers W1, W2 and W3 installed." Directly below that statement this statement appears which confirms the first statement: "? Analog band input on J1/2 pin 9 with reference voltage on J1/2 pin 4:" If you look at the schematic it shows Pin 9 as Reference voltage (8v) and Pin 4 ALC (band voltage) So they are reversed. Since the wording and the schematic disagree. Does anybody have any idea which is correct? My unit is not working properly.? I sent it in for repair but 1 hour of labor is about the cost of the unit.?

No output from the 15 MHz crystal. The other three bands are showing good output. I checked the relays K1 and K2 to verify each has pins 3 to 4 conductivity when on 40 meters (set radio to 40 meters, power down, and remove filter board since relays are latching. One side of crystal checks good to ground and the other side checks good to P1 pin 4. Ordered new 15 MHz crystal from Elecraft. Thanks for the advice. Once I got the RF volt meter it took a few minutes to find the problem. 73 and thanks again!

Check the RF voltage at pin 4 of P1 on the band board. You should read 70mV or more with an RF Probe or 200mV+ peak to peak if using a 'scope with a 10X probe. A good working K1 will develop at least 5 watts. Make up an RF probe if you don't have one. It does not have to be fancy, just stick the component leads through a piece of cardboard and solder the leads together.

It is a matter of understanding the frame of reference for the markings. The KRC2 was originally designed as a peripheral for the K2, so the interface ports use the K2 I/O port details. On the KRC2 schematic, 8R, VRDET, 12CTRL, ALC and AUXBUS are all K2 signals that the KRC2 can use for various functions. When used with other transceivers, they are repurposed (the benefits of using a microprocessor) to make best use of that device. The KRC2?s Icom band voltage sensing makes use of a feature of the processor, that is a voltage reference pin that exists only on the AN3 port, which is connected to pin 4 of the DE9 connectors. This particular setup was added late in KRC2 development to resolve issues with Icom?s band voltage system. It requires that the actual band voltage be connected to ANA1 of the micro, which is pin 9 (marked 8R) on the DE9 connector. Again, the 8R and ALC schematic markings have nothing to do with Icom signals, but reflect signals on the K2 IO port. I will communicate with you directly to try to resolve your issues shortly. We sometimes make mistakes, and this question caused me to recheck the schematics and code, but rest assured that in this case the manual and schematic are correct. 73!

TCP and HTTP protocols happen at different layers of the network stack. TCP is at the transport layer, it defines how to send the data and deals with the actual transport of packets around the network. Whereas HTTP is just the common language at the application layer, at the very core it is just an instruction set. In short, you can use TCP and HTTP together , you can have TCP without HTTP. It sounds like you are trying to address a very common problem, which is true with most ISPs these days, almost no one has a dedicated IP address anymore unless they are paying for business level services. There are numerous ways to solve this, the easiest and "free" way would just be port forwarding on your router, of course perhaps you already thought of this and if your ATT Mobile system is actually just a wifi hotspot and your router doesn't support that than of course the port forwarding isn't an option. So assuming perhaps that you have already looked at port forwarding and Dynamic DNS and settled on NGROK, the real question is going to be how many connections do they make. I did look at some of the Elecraft Documentation, there does appear to be an HTTP component for connecting to your K3 Remote via a web browser, I also saw reference to TCP port 4626 for the KPA-500 remote. I don't know what other port ranges they use but my gut (and experience with networking) tells me that the free version with 4 tunnels will likely work fine. I hope this helps, feel free to reach out to me off the list for any networking related questions.

Here is what I'd do. Dig into OpenVPN. It's open source software, you can buy routers that handle it natively, or you can put an Raspberry Pi 3 on the end of your link. There is client software for just about everything out there. This is the correct use for a VPN (most of the advertised VPNs offer "security" that doesn't actually exist). You open up the VPN whereever you are, and you have one connection that magically becomes a really long ethernet cable. Your device anywhere in the world is on the LAN at your remote station. Doesn't matter if you have 5 connections, or 5,000. As far as AT&T can tell, it's just one. 73 -- Lynn On 5/21/20 9:08 AM, K5WA wrote: > This may be a Wayne/Eric question but if anyone else knows for sure, please chime in. > > > > I?m setting up a new remote system and want to plan properly for the pair of K4s I?ve got ordered.

That was a big day for me. The first QSO since November since I live in a faraday cage and I haven't wanted to haress the management at my retirement community about antennas, since they are up to their eyebrows dealing with Covid-19. I hauled my KX3 out to a picnic table about 200-300 meters from the nearest building with electricity and QRM, and set it up with the AX1. I was abou 100 meters from the largest local river, down in a valley. I had a brand new Bioenno 6AH battery to power it since I had problems getting more that 3W out with the internal Enloop batteries. With this setup, everything worked FB. S0-1 noise and good reception. It was my first QSO with the AX1, my first time checking into the Elecraft net from New Hampshire, in spite of many trials from what should have been a better location -- near the top of a hill with a 2 element wire beam The only thing that was about the same as checking in from CA was NC0JW. He continued to be the best relay for my checkin. He has really good ears. Thanks again Jim. 73 Bill AE6JV PS. After the net, I made a 40M FT8 QSO with AA4SS which showed that the AXE1 extender was doing its job.

I have it up on a 3/8 in spacer above the carpet to keep it a bit cooler. I power my KX3 from the back of the KXPA100. I had the amp and KX3 on when a loose usb cable that was normally connected between my computer and my Signalink, had been disconnected to connect the signalink to my Raspberry Pi. While the USB cable connected to the computer was loose, it curled around I accidently kicked it and it slid under the power supply and contacted one of nuts on the bottom of the power supply and sparked. My KX3 stayed on for a few seconds, then shut off. When I tried to power it up again, it stayed on for about a second or so, then powered off. I checked the Astron power supply and it continues to put out 14.5V. I connected it back to one of the two Anderson PP connectors on the KXPA100 and there are no led's lighting up when the KXPA100 is on. I put a volt meter to the other Anderson Power Pole at the back of the KXPA100 and it is showing 4.6 v. output, not the normal 12 + V. I connected the 14.5 v. supply directly to the KX3 and it behaves the same; stays on for a second or so, then powers off. So, it appears that usb cable that found it's way under my power supply, has done some kind of damage to both my KXPA100 and KX3. I know there is no service currently at Elecraft, and when service resumes, it may be months before I can get the equipment repaired. To say I am frustrated would be a gross understatement. I can use my K2 and KX2, but both will be QRP. I am turning to the group to get any advice you might have at this point.

Then, look up EEINIT in the manual (it?s on page 46 in my version). I DO NOT recommend you do a factory reset. A reset won?t really buy you anything unless the radio isn?t working. And importantly, you will lose some important internal calibration data. And unless you?re just a glutton for punishment, you don?t really want to redo it all, unless you think something is out of whack.

Unplug it and let it clear out the cob webs. There are some fault protection modes that only clear with removing power and letting things discharge. Specifically, the crowbar circuit may not "uncrowbar" until everything is discharged. Second, you may have to do surgery. I have replaced transistors and LM723 chips before.

I had the amp and KX3 on when a loose usb cable that was normally connected between my computer and my Signalink, had been disconnected to connect the signalink to my Raspberry Pi. While the USB cable connected to the computer was loose, it curled around I accidently kicked it and it slid under the power supply and contacted one of nuts on the bottom of the power supply and sparked. My KX3 stayed on for a few seconds, then shut off. When I tried to power it up again, it stayed on for about a second or so, then powered off. I checked the Astron power supply and it continues to put out 14.5V. I connected it back to one of the two Anderson PP connectors on the KXPA100 and there are no led's lighting up when the KXPA100 is on. I put a volt meter to the other Anderson Power Pole at the back of the KXPA100 and it is showing 4.6 v. output, not the normal 12 + V. I connected the 14.5 v. supply directly to the KX3 and it behaves the same; stays on for a second or so, then powers off. So, it appears that usb cable that found it's way under my power supply, has done some kind of damage to both my KXPA100 and KX3. I know there is no service currently at Elecraft, and when service resumes, it may be months before I can get the equipment repaired. To say I am frustrated would be a gross understatement. I can use my K2 and KX2, but both will be QRP. I am turning to the group to get any advice you might have at this point. Thanks so much! 73, Terry, N7TB From donwilh at embarqmail.com Fri May 22 12:56:57 2020 From: donwilh at embarqmail.com (Don Wilhelm) Date: Fri, 22 May 2020 12:56:57 -0400 Subject: [Elecraft] Elecraft K2 firmware update In-Reply-To: <1590122332796-0.post@n2.nabble.com> References: <1590122332796-0.post@n2.nabble.com> Message-ID: <25e66882-32c5-ca08-c384-7ee873d2fa76@embarqmail.com> Al, Yes, that is the current level firmware, and you do not need to update the KSB2 firmware unless you want the latest functions. Before updating the firmware, download the K2 A to B instructions. It has a nice chart for recording your menu settings - they will all be reset. You will need the internal counter probe to record the BFO settings. If your K2 serial number is below 3000 and you have not installed the KIO2 or the KPA100, you will have to make the Control Board modification for the sidetone source. The mod is shown in the KIO2 and the KPA100 manuals. 73, Don W3FPR On 5/22/2020 12:38 AM, W4RAM wrote: > Good morning, > I am looking for assistance with the following: > My Elecraft K2 show firmware version: 2.01 and 1.02. > Is the #FWK2MCIO the correct kit that I need to update the firmware to 2.04 > and 1.09? > If the K2 have the KSB2 SSB Module, do I need complete any other firmware > upgrade? > > Thank you for any advice and assistance. > > V/R > > Al > W4RAM > > > > -- > Sent from: http://elecraft.365791.n2.nabble.com/ > ______________________________________________________________ > 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 donwilh at embarqmail.com > From donwilh at embarqmail.com Fri May 22 13:07:00 2020 From: donwilh at embarqmail.com (Don Wilhelm) Date: Fri, 22 May 2020 13:07:00 -0400 Subject: [Elecraft] Reset Third-Hand KX3 In-Reply-To: <65FF98A6-32E8-4048-9874-BC0F48683062@icloud.com> References: <65FF98A6-32E8-4048-9874-BC0F48683062@icloud.com> Message-ID: Tommy, I would not recommend doing a Reset to Factory Defaults unless there is a problem.

The entire configuration which I described has worked just fine ever since I acquired MORTTY last fall. I have used it in this configuration for thousands of contacts - paddle [and usb from computer ] into MORTTY and then into K3. The last time it all worked was for the 19z CWT on Wednesday. However, when I was setting up for the 03z CWT without making any changes from 19z except to change contests on N1MM+, when I set and saved the configuration, it first acted as a straight key [which is to say, either paddle simply gave a steady dah until I released it]. I then rebooted N1MM+, hit F3 [tu], and at that point the K3 gave some dits and dahs, and then would not do anything. When I took everything apart, I suspected the MORTTY, but putting the paddle directly into either paddle or key port on K3 produced nothing at all - would not key K3 no way no how. Tried the MORTTY on my K/W 480, and it worked fine. Key into 480 works fine in either the paddle or key port. I can only conclude that since the MORTTY works fine, the cables work fine, and the paddle works fine, that leaves only the K3 which does not work fine. Today I rebooted the K3 and computer several times in various configurations - N1MM, paddle with MORTTY, paddle direct to key port and then to paddle port. The first time I did it I noticed that both red and green lights on MORTTY lit up the first time I hit Enter on N1MM after configuring it, but no response that I remember from K3. I thought ESM must have disconnect itself in N1MM but it was OK. After that first attempt, I reconfigured ports in N1MM, still no ESM, no response from K3, and no lights on MORTTY. Nothing happens. Has to be K3 problem, but what? Receiver works OK.

Does the K3 keyer work? A string of dits to one side, a string of dahs to the other? Responsive to the K3 speed control? Then I'd plug the paddle into the K3 KEY input, and see if pressing the paddle to one side causes a solid key down. If that all works, the problem probably isn't the K3. My guess is that you may have plugged the external keyer into the K3's paddle input. It should probably instead be plugged into the K3's KEY jack. Both are adjacent 1/4" phone plugs and I've certainly made this mistake myself. Good hunting! 73 de Dick, K6KR -----Original Message----- From: elecraft-bounces at mailman.qth.net > On Behalf Of Madison Jones Sent: Friday, May 22, 2020 13:36 To: Elecraft at mailman.qth.net Subject: [Elecraft] Keyer goes berserk Neither the key nor paddle work on my K3. Using N1MM+ with a paddle and MORTTY keyer hooked up, when attempting to send a command via the keyboard, the K3 gave gibberish. When I attempted to use the paddle, it acted as a straight key. Rebooted everything with the same result. After testing the computer, all cables, connectors, the paddle, and the MORTTY interface and finding all will operate satisfactorily with a Brand X transceiver using the same N1MM+ program, same computer and with a paddle, I hooked everything back up to the K3. Now the K3 will not key at all, either through the program or manually with the paddle. Any suggestions before I send it back to Elecraft? 73 Madison W5MJ ______________________________________________________________ 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 ghyoungman at gmail.com Fri May 22 18:50:46 2020 From: ghyoungman at gmail.com (Grant Youngman) Date: Fri, 22 May 2020 18:50:46 -0400 Subject: [Elecraft] Keyer goes berserk In-Reply-To: References: <003701d63081$61c2d040$254870c0$@elecraft.com> Message-ID: <192F6902-3B6C-4B47-A3AE-77B2A84A3F43@gmail.com> Are you sure you didn?t inadvertently turn off VOX while the radio is in QSK mode? > On May 22, 2020, at 6:25 PM, Madison Jones wrote: > > When I took everything apart, I suspected the MORTTY, but putting the > paddle directly into either paddle or key port on K3 produced nothing at > all - would not key K3 no way no how.

The NR has 32 settings to scroll through, with a noticeable delay to build each one after selected. Also a delay to rebuild every time the width filter is changed. I expect the annoying delays will not be present on the K4 with the faster processor, but what of the filter selection: will we still need to scroll sequentially through long strings of NR & NB presets?

I ran across this when doing some mods and the instructions said to reinstall them but my early 4xxx K3/100F didn't have them. When I asked the Elecraft tech he said they were added because of the higher duty cycle digital modes. As a minimum make sure those screws are tight. 73, Brian, K0DTJ > On May 22, 2020, at 16:03, Eric KG6MZS wrote: > > Hello All, > > I?ve searched the reflector's archives and haven?t found anything on this, so here goes. > > I have an aging K3/1000 (sn 3045) and I wish to preserve its operating life.

What s/n is your 1500? On later s/ns we changed a resistor in the ps fan circuit to slow them down a bit more. An alternative is to swap your ant 1 and 2 connections, putting the 6m ant on ANT 1.

Message-ID: The backstory as briefly as I can make it: I wanted to place my home theater subwoofer in the corner of our living room; doing so required running two speaker wires and a coaxial cable under the house and plugging the subwoofer into a different outlet than the AV receiver; this in turn resulted in ground-loop hum (because of a tiny difference in potential between the two outlets) which I worked around with a set of 1:1 low-frequency audio isolation transformers. The subwoofer is of a type that produces a signal based not only on the LFE channel, but also on the left and right speaker channels, thus the two speaker wires along with the coaxial cable. Now the subwoofer is picking up common mode noise on 20m, which isn't terribly surprising, as this happens a good bit with consumer-grade electronics. I'm hoping to mitigate this with some substantial ferrite clamps for all three connections and as many turns as I can get through them. My hunch is that the best place in the path to clamp them on will be immediately before the connection to the speaker itself, on the speaker side of the isolation transformer, but I wanted to get the opinions of folks who have solved this problem in the past to see if there's any reason the ferrites should come before the isolation transformers.

I have my sub-2 output connected to bass shakers on my sofa, and the wiring picks up an incredible amount of RF on 20. As my wife found out when she was taking a nap in the room while I was contesting. As soon as I switched to 20 she was getting rumbled to the pattern of CQ TEST. That was an interesting conversation, and something I will look at this summer. As for your low frequencies getting into your left and right main, why not switch them to "small" in the AVR menu, and let the sub do all the work below 80 Hz? I have had some luck putting ferrites just before the speaker terminals in the past. I sadly cut all my speaker cable to length so there's no room to wind around a core, so these will need to be clamp-ons for me. I get into my center and surrounds on 40 and 20. Or I can tell my XYL to nap in the living room, since there's just the two of us in the house. - pjd -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Nicklas Johnson Sent: Saturday, May 23, 2020 12:38 PM To: elecraft Subject: [Elecraft] ferrites for subwoofer: before or after isolation transformers?

I've been stuck on J6 since Feb 20 and not much to do here but play radio. The K3 and KPA1500 are on 24/7 in a dusty humid atmosphere (but made over 86,000 QSOs so far since Feb 20). I can imagine a time in the NEAR FUTURE where the fans will need to be replaced due to use. Is there any recognition of this with a "replacement fan kit" when it's time...? Dr. William J.

It is important you also protect the amp from stray RF. If the speaker cable is picking up RF, and feeding it back into the audio amp output stage, you can get rectification within that stage in the amp, thus feeding actual audio, (not RF), back down the speaker cable into the speaker(s), and then you start hearing things on the speaker(s). I had a ham friend living 700 or 800 feet from me-- when he lit off his KW, I would hear SSB in the speakers, even with the amp off, and unplugged. This was happening via the method above.

Consumer electronics is notorious for this problem. I'm hoping to mitigate this with some substantial ferrite > clamps for all three connections and as many turns as I can get through > them. What three connections are we talking about here? Is it speaker cable or unbalanced audio coax? If speaker cable, replace with twisted pair, which can be built from two colors of ordinary THHN house wire. Spool out lengths of the two colors, put one end in a vise (or equivalent), the other end in a drill, and slowly twist a lot. When you've twisted more that you think is needed, lay the drill down overnight to let the cable develop some memory. When you do remove it from the drill, it will untwist some. That's why it's best to twist it a lot. Chokes as Dave recommended should be applied individually to each audio cable and the AC cables for both the receiver and the sub-woofer. > > My hunch is that the best place in the path to clamp them on will be > immediately before the connection to the speaker itself, on the speaker > side of the isolation transformer, but I wanted to get the opinions of > folks who have solved this problem in the past to see if there's any reason > the ferrites should come before the isolation transformers. If you have run AC as I've recommended, the transformers are probably not needed. 73, Jim K9YC From huntinhmb at coastside.net Sat May 23 15:03:10 2020 From: huntinhmb at coastside.net (Brian Hunt) Date: Sat, 23 May 2020 12:03:10 -0700 Subject: [Elecraft] K4 NR & NB In-Reply-To: References: Message-ID: <0426608e-4385-8ad9-0620-28e4d84b26fa@coastside.net> Will the NR "mixed mode" (NRmF5-x and above) where some of the unprocessed signal is mixed with the processed signal be available on the K4 as it is on the K3??

And of course there's no "one size fits all" for RFI problems. I think it's somewhat likely I have multiple problems going on here too; I noticed, for example, that even when it's completely disconnected from all its audio inputs, I can still hear a little racket on the sub; it may need a hefty ferrite on the power cord, or I suppose it's always possible it's picking up 20m from the speaker coil, then rectifying that. I won't know until I get some appropriate ferrites delivered to test out (mid-week). Sadly, it seems like most consumer-grade audio equipment is optimized more for cost than for design quality and RFI suppression, even equipment that's supposed to be "high-end." And then sometimes you can buy a piece of cheap gear and it rejects RF better than high-end stuff. Kind of a crap shoot. I appreciate all the suggestions and pointers. In the absolute worst case, I can always play on another band when my better half wants to watch a movie or play a game, too.

Maybe there is a K3 setting incorrect like the mode or it is set to TX split on the wrong mode. Does the K3 side tone make any sound? I am curious if RTTY sends with the key plugged in?

If so, I've missed it. I'm particularly interested in the user interface compared to the K3. On the K3 the NB has 21 DSP settings and 21 IF settings which have to be scrolled through sequentially to find the best ones. The NR has 32 settings to scroll through, with a noticeable delay to build each one after selected. Also a delay to rebuild every time the width filter is changed. I expect the annoying delays will not be present on the K4 with the faster processor, but what of the filter selection: will we still need to scroll sequentially through long strings of NR & NB presets? Despite the limitations of the K3 filters I have found them to be very useful for my local noise problems. Still, I hope there is something better on the K4... 73, Drew AF2Z ------------------------------ Message: 4 Date: Fri, 22 May 2020 21:19:30 -0500 From: Madison Jones To: donwilh at embarqmail.com Cc: Elecraft at mailman.qth.net Subject: Re: [Elecraft] Keyer goes berserk Message-ID: Content-Type: text/plain; charset="UTF-8" Hi Don I checked VOX, and it is on and has been on.

I ran across this when doing some mods and the instructions said to reinstall them but my early 4xxx K3/100F didn't have them. When I asked the Elecraft tech he said they were added because of the higher duty cycle digital modes. As a minimum make sure those screws are tight. 73, Brian, K0DTJ > On May 22, 2020, at 16:03, Eric KG6MZS wrote: > > Hello All, > > I?ve searched the reflector's archives and haven?t found anything on this, so here goes. > > I have an aging K3/1000 (sn 3045) and I wish to preserve its operating life.

Message-ID: Content-Type: text/plain; charset="UTF-8" The backstory as briefly as I can make it: I wanted to place my home theater subwoofer in the corner of our living room; doing so required running two speaker wires and a coaxial cable under the house and plugging the subwoofer into a different outlet than the AV receiver; this in turn resulted in ground-loop hum (because of a tiny difference in potential between the two outlets) which I worked around with a set of 1:1 low-frequency audio isolation transformers. The subwoofer is of a type that produces a signal based not only on the LFE channel, but also on the left and right speaker channels, thus the two speaker wires along with the coaxial cable.

I'm hoping to mitigate this with some substantial ferrite clamps for all three connections and as many turns as I can get through them. My hunch is that the best place in the path to clamp them on will be immediately before the connection to the speaker itself, on the speaker side of the isolation transformer, but I wanted to get the opinions of folks who have solved this problem in the past to see if there's any reason the ferrites should come before the isolation transformers.

I have my sub-2 output connected to bass shakers on my sofa, and the wiring picks up an incredible amount of RF on 20. As my wife found out when she was taking a nap in the room while I was contesting. As soon as I switched to 20 she was getting rumbled to the pattern of CQ TEST. That was an interesting conversation, and something I will look at this summer. As for your low frequencies getting into your left and right main, why not switch them to "small" in the AVR menu, and let the sub do all the work below 80 Hz? I have had some luck putting ferrites just before the speaker terminals in the past. I sadly cut all my speaker cable to length so there's no room to wind around a core, so these will need to be clamp-ons for me. I get into my center and surrounds on 40 and 20. Or I can tell my XYL to nap in the living room, since there's just the two of us in the house. - pjd -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Nicklas Johnson Sent: Saturday, May 23, 2020 12:38 PM To: elecraft Subject: [Elecraft] ferrites for subwoofer: before or after isolation transformers?

I didn't think about adding one at the amp; though I haven't had problems with any common mode noise getting into the amp from the other speakers in the room, I can't be sure about the LFE coaxial cable, so that wouldn't hurt.

Besides just needing a thorough alignment, have noticed that on 40 meters at 7184.00, the audio is extremely distorted but not on any other part of that band. I have the owners manual, nothing in trouble shooting about distortion. Ser. #3631. K2 IOC 1.07. K2 MCU 203.

For more than 30 years, virtually ALL electronics has been built with Pin One Problems. This has as much to do with stupid as it does with cheap. When Neil Muncy, ex-W3WJE, now SK, first exposed it in 1994, virtually all Pro equipment had Pin One Problems. Every ham rig I studied the last time I was in Dayton and last year in Visalia had Pin One Problems, including Elecraft. THAT'S the major reason we need ferrite chokes on all the "receiving antennas." It's also a major mechanism coupling for RF noise OUT of the box. The Pin One Problem occurs with the AC "Green Wire" (Equipment Ground) and with antenna jacks in home entertainment systems AND in CATV and DSL systems. They all put noise on the coax shield and the Green Wire. 73, Jim K9YC From kevinr at coho.net Sat May 23 22:51:58 2020 From: kevinr at coho.net (kevinr) Date: Sat, 23 May 2020 19:51:58 -0700 Subject: [Elecraft] Elecraft CW Net Announcement Message-ID: <8b6d2339-e0c3-577e-f957-e9de8d1cc910@coho.net> Good Evening, ??

How distorted depends on the noise strength or pulse width of the noise. You may reduce RF gain of your receiver to improve relative signal to noise ratio and disable the noise blanker. 73 de JH3SIF, Keith > 2020/05/24 11:38?Mike Duke ????: > > I have a new acquisition.

I had forgotten to say that, this particular K2 has only one add on board and that would be the side band board. There is no noise blanker. Now I did go through each band looking for a aegment of distortion that may be present on the other bands but being the time of day is evening, could only check on 80 and 40 meters. Although earlier before sunset there was still traffic on 20 meters but the whole band was clean. All of 80 meters was clean as well was 40 (except again on 7.184). It sounds like a warbly distortion that a Ten-Tec Omni D or Corsair would demonstrate when the VFO needs to be rebuilt. Tomorrow I will record an audio clip and post it. Thank you again.

Started with optoisolators but when trying to go SO2V I couldn't make them work with the outputs paralleled. Now I have 2 db9 serial plug with a single 2n2222 & 1k resistor in each, outputs paralleled into a db15hd for the acc on the K3. PTT is via CAT. This is the simplest solution that I have found. I use I/O usb to serial converters with 4 or 8 ports. Enough to run everything on rs232. Only use usb for CAT and sound. This is the least number of cables and connections I have used, and I like how it works. Am really starting to regret selling the house and moving into an apartment building though.

In-Reply-To: References: Message-ID: Mike, This is the Weird At One Frequency (WAOF) problem. It occurs at the point where the PLL and VFO frequencies cross, and that usually occurs near 7185kHz. First step in the cure is to flush cut every lead in the vicinity of RF Board U4 and the VFO - so that those small leads cannot act as an antenna. Then retest. If the problem still exists, try removing C88 (soldered on the bottom of U4 between pins 12 and 13). Retest again. If still present, remove RFC15 - again on the bottom of the board between U4 pin 16 and the adjacent solder pad just to the right of pin 16 - replace with a very short jumper wire. Good luck with it - not all K2s suffer this 'malady', but unfortunately yours does have the problem. Does your noise problem occur if you disconnect the antenna? That does sound like some noise being picked up by the antenna. I have never seen that behavior in a K2 before, and I have repaired over 1000. 73, Don W3FPR On 5/23/2020 10:38 PM, Mike Duke wrote: > I have a new acquisition. I traded my Corsair II for a K2.

Actually, I had to run the WATTMETER, and BOTH the LP (5W) and HP (50W) calibrations to ?cure? the same issue you are observing. Installing the KSYN3A in a K3 results in lower output on 6M when the KPA3 is active, i.e. the requested power is greater than 12W. When the power requested is less than 12W, the KPA3 is inactive (bypassed), the output power is within measuremt accuracy on an external wattmeter to what is requested by the K3 power setting control. When the power requested is greater than 12 W, i.e. 100W for example, what I have observed is at 52.000MHz the external wattmeter reads 85W, and at 50.500MHz only 63W is realized. There is little difference in the output power measured in each case with/without KAT3 tuner ?bypassed? or ?enabled and matched? at the operating frequency?s outlined above. It appears that this anomaly occurs only on 6M, I don?t know if there is a solution or fix for the above.

His suggestions will leave you in class D. Why? Two things - if the computer controls the radio (and it should for logging and sending exchanges), then it must also be run on emergency power. Second, the addition of a wall charger for the batteries puts you firmly into class D. You can charge the batteries off solar panels to remove this restriction. Field Day at WVARA station K6EI consists of many QRP stations all running off battery, and all are charged by solar panels. For SSB, my 20/80 meter station will run the entire event from a single Marine battery (bought at Costco for $75). That powers K3S, P3, Computer (15? MacBook Pro) and lighting. It is charged during daylight by a 100 watt solar panel. By the time we break down on Sunday, the battery is fully charged. That solar array is a game-changer, turning this from a multiple battery event into one handled by a single deep-discharge marine battery. Unfortunately, it appears we won?t be doing FD this year from the great vista overlooking the San Francisco Bay area (really a spectacular view), although we haven?t been told the definitive no just yet. Be sure to read the full Field Day rules for what is legal and what isn?t. They tend to be rather strict. 73!

Q. What equipment at our Field Day site must be operated off of the emergency power in order to claim the 100-point per transmitter bonus? A. You must operate all transmitting and receiving equipment from emergency power. If you use a computer for digital modes, and/or to control or operate the radio, it also must use emergency power. If the computer is used only for logging and is not keying the transmitter, it does not need to be emergency powered. http://www.arrl.org/files/file/Field-Day/2019/2019-FD-FAQ-RevA.pdf\ Also, batteries may be charged from commercial power, just not during Field Day operation.

If you use a computer for digital modes, and/or to control or operate the radio, it also must use emergency power. If the computer is used only for logging and is not keying the transmitter, it does not need to be emergency powered.? Now this is an answer to a question about the 100 point emergency power bonus, but we have been told it applies to normal operation as well. The key is ?controlling the transceiver?. If it even changes bands or causes transmission, then it must be operated on emergency power. If anyone questions the charging requirements, section 6 ?Miscellaneous Rules:? states: "6.9. Batteries may be charged while in use. Except for Class D stations, the batteries must be charged from a power source other than commercial power mains. To claim the power multiplier of five, the batteries must be charged from something other than a motor driven generator or commercial mains." Very clear. 73!

That depends on what other options you can buy that best suit your plans for each location, and will certainly vary from one QTH to another. It's a very nice light weight, super-portable antenna designed by Wayne himself, who is a serious backpacker, but it's really designed for pedestrian/bicycle mobile operation. > What else is not included that I should be considering? Mic, paddle, computer, one or more cable adapters if you want to work WSJT modes. For longer operating events, one of these outboard batteries or a second internal Elecraft internal battery. https://www.bioennopower.com/collections/12v-series-lifepo4-batteries When comparing rigs, consider that Elecraft backpacking rigs include a very good receiver and preamp, and draw FAR less current on receive than the JA rigs -- ~150mA for the KX2 and KX3, compared to 1A or more for the others. This greatly extends battery life. The KX2 has a built-in mic. https://elecraft.com/products/kx2-ssb-cw-data-80-10-m-transceiver 73, Jim K9YC From macymonkeys at charter.net Sun May 24 17:40:57 2020 From: macymonkeys at charter.net (Macy monkeys) Date: Sun, 24 May 2020 14:40:57 -0700 Subject: [Elecraft] Field Day In-Reply-To: <4cfd30bb-197b-c2d3-c760-7eb71268e0f3@gmail.com> References: <3b4fbae9-b29f-32da-5f93-7ff0ab366023@audiosystemsgroup.com> <4cfd30bb-197b-c2d3-c760-7eb71268e0f3@gmail.com> Message-ID: <897C2DBA-DEB7-42F2-B54F-EC58788D4660@charter.net> They should give extra credit for using pencil and paper...

The cited 8-hours on the battery is very accurate. I have found no need for a second internal battery. You just seldom sit on a SOTA summit or a field event for 8 hours. Even running at 10W, you get a good 6 hours. The KX2 has a barrel jack for external DC power, which it can be run off of in the shack, or for an external battery in the field if desired. > If the tuner isn't included, how necessary is the tuner (I have an end fed > 80 and am building an end fed 40). I would recommend it. I have built no-tune antennas for portable use, only to find a higher than I want SWR once I get to the field or the SOTA location. There is no electrical ground to speak of on a mountain peak, so an antenna will tune different there than your back yard. The ATU is so convenient compared to piddling with wire lengths and radials in the field to get it tuned and low SWR just to get on the air. > What else is not included that I should be considering? The KXPD2 paddles are also very convenient. No need to haul around separate paddles for field operations when you have one right on the front of the rig. The paddles, plus the front panel SPEED control, makes it snappy to change CW speed when needed. I bought mine when first released. It works like new, as advertised, and a hearty rig even for SOTA and other less-than-ideal situations.

Most end-fed antennas need a COUNTERPOISE to serve as a return for the current (and the field) produced by the antenna. An earth connection is NOT a good counterpoise, because the earth is really a big resistor, so it burns most of the transmitter's power if that's the only counterpoise. Instead, smart operators provide some intentional counterpoise connected to the BNC shield, like multiple radials or a single wire running in some direction other than the antenna. If the wire or the radials are laying on the ground, they will couple some of the earth's resistance and burn some TX power. This can be reduced by elevating the wire or the radials. When operating portable, I've draped a single wire counterpoise over the tops of low brush. 73, Jim K9YC From pfizenmayer at q.com Sun May 24 19:03:32 2020 From: pfizenmayer at q.com (HP) Date: Sun, 24 May 2020 19:03:32 -0400 (EDT) Subject: [Elecraft] consumer-grade audio equipment / RFI suppression, In-Reply-To: References: Message-ID: <1154126441.112357827.1590361412949.JavaMail.zimbra@q.com> Last summer I kept hearing noise bursts on 6 meters on my K3 that seemed to follow a beat - Neighbors behind me were playing "music" with lots of bass notes on outside speakers.

This is typical of Elecraft - if you don't need it, you do not have to buy it, they do not include it as part of the basic package. The microphone and paddles are also not part of the basic package. Is your end-fed antenna tunable with a capacitor? If so, then no tuner is required - otherwise yes. If you want to operate 20, 17 and 15 meters with an antenna that is short and portable, then the AX1 may be the thing for you. If you are planning operation from the home station, use resonant antennas mounted higher for better results. The AX1 (and AX1E for 30 and 40 meters) does a good job when you have to set up quickly and operate in a portable situation. The KX2 tuner is required with the AX1 antenna. On your end-fed antennas - you do need a counterpoise of about 0.05 wavelengths (see the W8JI experiments). A just as good portable antenna is a BNC to binding post adapter connected to the KX2. A 58 foot length of wire and a 27 foot counterpoise will be a good performer for 80 through 10 meters (no feedline). Yes, you will need the KX2 tuner with that arrangement. The counterpoise can be laid on the ground and the radiator thrown over a limb or tall bush. One of the KX2 Field Testers who operates mostly SOTA has determined that those lengths work well. I can't answer about your 80 and 40 meter end feds, if they are tuneable with a capacitor, then you do not need the tuner, but if they have UNUNs which tie the bottom of the primary and secondary together, they will use a part of the feedline for a counterpoise. The counterpoise for a tuned end fed antenna needs to be only 0.05 wavelength long (see the W8JI experiments). 73, Don W3FPR On 5/24/2020 5:05 PM, Doug Daniels wrote: > I'm looking at the potential purchase of a KX2.

I?m not a lawyer nor do I play one on television, nor did I stay at a Holiday Inn Express last night?. ;-) It seems to me that the ?spirit? of the FD rules is that anything that impacts the transmission/reception/interpretation of RF communications cannot be on a commercial power source if the site is going to claim ?emergency power? as the power source. So if a Local Area Network is installed to pass data between stations at the site for logging purposes or coordination of transmissions, or is involved with digital signal modes, or if there is computer equipment, monitors, or ancillary equipment is used as part of the system to process information as part of the overall operation, then they all must be off commercial power if ?emergency power? is to be claimed as the power source. A Flex system that uses the LAN to communicate between Maestro, Antenna Genius, PGXL Amplifier,etc. may only be running CW and SSB without a PC would have to have that LAN on emergency power as the LAN is integral to the setup/operation of their communications equipment. If a laptop is running SSDR and has an external monitor, both devices would need to be off commercial power. If a laptop is logging contacts or being used for digital modes, it and anything else attached to it would also need to be ?off the grid? to claim emergency power status. The bottom line is that those that are involved with the design/installation of a field day site shouldn?t be looking for ?exceptions? to the rules but ask themselves whether their site setup meets the ?intent? of the rules. Or, to put it another way, if the site did have a commercial feed available and that feed was lost due to a power outage, would the site be able to continue operating regardless on the existing sources of power that they?ve installed at the site? If the answer is ?no? (e.g. they need to rewire/reconfigure to accommodate the loss of commercial power to keep operating as intended), then that site doesn?t qualify as running on emergency power until such time as they can indeed operate from start to finish without interruption.

My point is that these clarifications should be part of the FD RULES, not an FAQ. To me, an FAQ is answering questions raised because the Rules are poorly written or incomplete. If I were running things, I would ban all FAQs and tell the author(s) of the basic document(s) to finish their job! When I first did FD in 1957, we logged on paper and kept paper dupe sheets. One guy operated, a second kept the log and the dupe sheet. The rules have not changed much since then, and to some extent, those days are still the mindset of both the League and many club participants. BTW -- my question about the monitor was rhetorical, and I don't agree with your logic about it. It's part of the computer's user interface -- we humans can't operate the computer to control a radio without it. The good thing about requiring true backup power for the computer causes us as hams to think more seriously about running in emergencies. The bad thing is that independent of the mains AND not powered by a generator is that most laptops now need 16-20V at their power socket, it's hard to find QUIET DC-DC converters, and it probably takes more power to run the laptop than to run a KX3. There's the interpretation of another contesting rule that is the basis of "split site" operation during Sweepstakes. Two operators run one day from their own QTH, then trade QTHs for the second day. This was originated by our own big club, NCCC, and has since been adopted by other clubs. The RULES says that 1) each operation needs to use a different call (usually a Club call) and 2) a TRANSMITTER may be used with only one call during a contest. This means four calls and four transmitters. Starting out in broadcasting a few years after that first FD, I've always viewed a power amp as part a transmitter, but the Rules are not interpreted that way -- they apply it only to the transceiver! 73, Jim K9YC On 5/24/2020 5:09 PM, Nr4c wrote: > The monitor does not control anything, so it can be powered anyway you want.

Take this for example - "3. Date and Time Period: Field Day 2020 will be held June 27-28. Field Day is ALWAYS the fourth full weekend, beginning at 1800 UTC Saturday and ending at 2059 UTC Sunday. 3.1. Class A and B (see below) stations that do not begin setting up until 1800 UTC on Saturday may operate the entire 27-hour Field Day period. 3.2. Stations who begin setting up before 1800 UTC Saturday may work only 24 consecutive hours, commencing when on-the-air operations begin. 3.3. No class A or B station may begin its set-up earlier than 0000 UTC on the Friday (Thursday afternoon or evening local time) preceding the Field Day period. Cumulative set-up time shall not exceed a total of 24 hours." This rule set allows a 1E station to operate for almost 27 hours. The contest start and end times are defined in rule 3.0. None of the subordinate rules say that a 1E station that performs all setting up after 1800 UTC Saturday is not allowed to operate for the full contest period. It takes me less than 1 hour to convert from mains power to running the entire station on a generator. The rules, as published, allow me to connect and start the generator after 1800 UTC Saturday and continue operating until 2059 UTC Sunday. ARRL representatives have told me that 1E stations may operate only 24 hours but the rules don't say that. 73, Andy, k3wyc From frantz at pwpconsult.com Mon May 25 10:57:15 2020 From: frantz at pwpconsult.com (Bill Frantz) Date: Mon, 25 May 2020 10:57:15 -0400 Subject: [Elecraft] Field Day In-Reply-To: Message-ID: Back around 1960, when IBM was developing the 360 series, the people working on the architecture document adopted a policy of not answering questions.

I basically agree with Jim about emergency planning. For me, FT modes are out (even if they could pass the necessary traffic) because they require accurate time. My MacBook Pro doesn't keep accurate time without a continuous connection to a NTP source. When I'm at home, that comes via Comcast, which requires mains power, and will probably fail for other reasons as well. In the field I use my cell phone, which has the same problems. Power is also difficult. At field day, I've used an inverter 12V to 120V to power my laptop power adapter. I don't have to describe why this solution is bad in so many dimensions to this group. To solve the laptop power problem, I built a computer using a single board computer and a 12V monitor from Adafruit.

Until about 15 years ago when I got my KX1, I mostly used linked dipoles, and other hard to erect antennas. Often I did not even set up for portable operation in a campground, mountain top, or just because it was too much effort. All that changed with my KX1 with a built in ATU. A typical antenna for casual portable operation is a simple 26 foot piece of wire and a 17 foot counterpoise wire laying on the ground. This worked great for 40, 30, and 20 meters, got me on the air in a few minutes, and produced many hundreds of QSO?s from my locations in Europe, the UK, and from various places around the ?lower 48? states. Now for sure this simple antenna was not equivalent to more complex antennas which I sometimes erect for field day, etc. So I would get the ATU for sure, since compromise, or very compromise antennas are often your only possibility. There are other ?magic? lengths of wire which enable operation on many other bands with an ATU. I now have and enjoy a KX2 with more power and a better ATU. I bought the AX1 since money was not a concern, however I suspect that many (most) wire antennas will outperform it, especially on 30 and 40 meters. You need to consider which modes of operation, the power level, then number of hours of operation in a portable expedition, etc. before deciding the battery configuration. One possibility is one internal pack, then an appropriate external battery pack with enough capacity for an activation. So far I really enjoy my KX2 with the paddle on CW and have even tested it on SSB a few times. No significant experience yet with the AX1.

It runs a pair of grid driven 8122, 400W tetrodes. The input is an untuned 50? load that can be easily set for LOW drive such that 5 W in will net you over a kilowatt out. The tubes are still available and with that input circuit, is always a good match for your SS radio.

So I took it apart to see what was going on. It is a rather clever assembly of standard hardware. There is a plastic clip that goes around a standard BNC right angle adapter. A phillips head screw goes through the clip and is used to hold the legs. There is a small nut on the screw which should be tightened to hold the screw firmly in place. Over the small nut is an internal lock washer, which just fits. The nut keeps it from turning and it in turn holds the legs in place. One leg goes on the inside of the lock washer and the other goes on the outside. Finally there is the locking knob. With this assembly, it is essential to loosen the locking knob whenever adjusting the legs. If you just pull the legs, it is quite easy to turn the nut and loosen it. If it is loose, it will turn and the legs will turn with it. 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | Ham radio contesting is a | Periwinkle (408)348-7900 | contact sport. | 150 Rivermead Rd #235 www.pwpconsult.com | --Ken Widelitz K6LA/VY2TT | Peterborough, NH 03458 From elecraft.list at videotron.ca Tue May 26 11:27:33 2020 From: elecraft.list at videotron.ca (Tom) Date: Tue, 26 May 2020 11:27:33 -0400 Subject: [Elecraft] Auto Information mode In-Reply-To: References: Message-ID: <000201d63372$2dfafc80$89f0f580$@videotron.ca> Hi A little trivia: The AI mode in the Elecraft radios is far from complete. Only a small subset of commands are available. On Yaesu radios, everything done on the radios is supported with AI and you see orders of magnitude faster performance. In fact it is so fast that you need to implement handshaking on the serial ports to prevent slower computers from buffering the incoming commands. On a Hexa Core I7-9800 CPU usage can hit 30% as it keeps up with all of the commands coming in when you turn the VFO dial rapidly. The resting CPU usage is 1% since no polling is occurring. The AI command is great especially since most of the traffic is usually just the s meter. So very good meter performance. 73 Tom va2fsq.com -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Andy Durbin Sent: May 26, 2020 11:16 AM To: elecraft at mailman.qth.net Subject: [Elecraft] Auto Information mode Many Kenwood and Elecraft transceivers support Auto Information mode.

Everything is working properly with the exception of one of my P3s. When I attempt to power it up, I just see a rapidly flashing boot loader message for a few seconds and then it turns off. This happens with or without connection to the external RS232 or IF jacks. It does have a SVGA board installed. The problem persists if it is powered from either of my two K3s (which run from different power supplies). I'm sure I'll have to open the thing up and check for connectivity problems, but I thought I'd ask first if anyone has observed this problem and might know what's going on to help shortcut the troubleshooting process. It's a bit of a pain to remove the P3 from the station setup, so I'd like to do it only if necessary. 73...

I noticed between one and two S-units increase in noise on a 10m dipole located within 40 ft. of the shack. I also noticed the same on 15m with a 40m dipole at the same distance. I added type 31 ferrite snap-on cores to the 240 VAC, the "high" DC voltage, and control lines at the power supply. Now, the noise is back to the ambient level which is still too high. Now I can copy another level or two of signals I couldn't copy as well prior to adding the ferrite cores. BTW, that previous level of noise disappeared when I powered the amplifier down and not the PSU. 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ From eadanbru at zeelandnet.nl Tue May 26 13:31:14 2020 From: eadanbru at zeelandnet.nl (Dan de Bruijn) Date: Tue, 26 May 2020 19:31:14 +0200 Subject: [Elecraft] KX-3 transverters Message-ID: <99be4041-0b6b-7dd5-9fbc-0d3591ddcd65@zeelandnet.nl> Hi Wayne and Eric, I own both a KX-2 and a KX-3 and I'm very happy with both units. De KX-2 is used during hiking and outdoor (not very much SOTA in the Netherlands), using the internal batterypack. The KX-3 is used as a homestation and in my Landrover, using an external battery. At 10 - 15 watt it is an ideal set. I fitted the 2 meter transverter KX3-2M in the KX-3 and although it is ideal to drive my UHF/SHF transverters at home, it lacks power in the field. Even at QRP, 2.5 watts is quite low. I'm wondering if it would be possible to put a 2 meter transverter (or a combination of a 4 - 2 or a 4 - 2 - 70 cm transverter) with a power of approx. 12 watt in the place of the batterypack.

Hi Bill, For 10M, I suggest three turns through a #31 clamp-on that's large enough to hold the turns.

That could be past 2100 UTC since, it appears, many don't read the rules/FAQ.

I guess I won't need to tear down this year since I'll enter in Category E, probably. I will still hear the CW in the swamp cooler.

It's a solder kit (no fan) and a relatively easy build. The build instructions aren't great and up to Elecraft standards but good enough to get the job done especially if you've done a few solder kit builds. It's great for portable ops especially when operating on battery power. A lot less power draw AND less than an S unit in difference on the "far end". Works great so far and I finished the build just over a year ago. I have no idea if they are in stock at the Hardrock 50 website (link below). https://www.hobbypcb.com/index.php/products/hf-radio/hardrock-50-hf-power-amp As to out of stock items at Elecraft I tried to purchase 2 KIO3B's and a KPA100 (someone at Elecraft can do the math on lost sales). And from the sales department over two weeks ago... yep you guessed it... OUT OF STOCK. And NO I wasn't willing to give Elecraft $$$ for some vague shipping timeframe in the future. Why you ask? I was ripped off in the past by a company "I trusted" and they subsequently went bankrupt and I never got my money back or the product ordered. Bottom line: I don't prepay for anything. If the product is in stock and I want it, then I'll buy it. Good luck on your hunt for an alternative AMP. 73, Scott AD5HS On 5/25/2020 9:31 PM, HamRadioJim wrote: > I have a KX3 and looking for an AMP (besides the elecraft brand) that is 100 > watts or more that will work flawlessly with it. > > I ordered the 100 amp from elecraft, but have been waiting over two months > for it, but they are out of stock and will be for some time. > > Has anyone purchased something else and has used it for a while with really > good results?

Plenty of stations are active at 1800Z and activity grows rapidly over the next few hours. Conversely activity steadily drops off on Sunday and it drops rapidly after 1800Z, there's not enough activity to compensate for lost time due to a late start on Saturday. This advice might be sub-optimum for QRP stations than benefit from less crowded bands. 73 Frank W3LPL ----- Original Message ----- From: "K8TE" To: elecraft at mailman.qth.net Sent: Tuesday, May 26, 2020 11:45:54 PM Subject: Re: [Elecraft] Field Day If you have operated FD recently (past multiple decades), you know there are NOT enough stations operating during those "extra" three hours to make it worth while. Of course, if you have plenty of beer and ice, I guess you could stay at the rig until there isn't anyone else left to work. That could be past 2100 UTC since, it appears, many don't read the rules/FAQ. By 1800 UTC, I am ready to stop operating, have a (one) beer, tear down, and listen to CW coming from the swamp cooler at home. I guess I won't need to tear down this year since I'll enter in Category E, probably. I will still hear the CW in the swamp cooler. The average life span for any "permanent" setup in my station is approximately 24 hours or until I read the next Elecraft Digest. I suppose that won't qualify for set-up time in Category E. Wait! I need to check the rules! 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ 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 donovanf at starpower.net From kevin at ve3syb.ca Wed May 27 02:23:32 2020 From: kevin at ve3syb.ca (Kevin Cozens) Date: Wed, 27 May 2020 02:23:32 -0400 Subject: [Elecraft] Field Day In-Reply-To: <1512100184.3715176.1590550847444.JavaMail.root@starpower.net> References: <1512100184.3715176.1590550847444.JavaMail.root@starpower.net> Message-ID: <299812b4-3417-4175-1a82-524a1aa44add@ve3syb.ca> > Conversely activity steadily drops off on Sunday and it drops rapidly > after 1800Z, there's not enough activity to compensate for lost time due > to a late start on Saturday. The other problem one runs in to are the self-appointed "FD police" who will refuse to work you as they will tell you it is past a given time and you are supposed to have ceased FD operations. It happened to me one time. I had a late set up which meant I should have been able to run the extra three hours. When I tried to contact someone in 6 land they refused the contact telling me my time was up. At that point I just called it a day. -- Cheers!

When I added my furnace, I made it part of the purchase contract that there was to be no new RFI. This makes the vendor very careful. Tell them it is a showstopper, and they will be responsible for RFI removal if RFI comes with the new purchase. Get it in writing if possible. Insist they call the manuafacturer and ask about RFI for the unit you are considering, and are there RFI kits for that unit, PRIOR to your purchase... Be careful assuming brand and model numbers will remain RFI quiet over time. Vendors change parts, and circuits, within a fixed model number all the time... What is RFI quiet today, may not be RFI quiet tomorrow... Take measurements first, before the install, and after install. Use this process: https://www.nk7z.net/sdr-rfi-survey-p1/ It is part I of III in a series on using an SDR to model your RFI environment. Perform the tests, save the results, then run them all again after install... I run a full sweep once a year here, and keep the results... Also see my March 2020 article in CQ on this subject... Good luck, and good for you for looking at this early!!! 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist ARRL Asst.

It is located right under our 30 ft tower with Yagis and wire antennas. There is no detectable elevation of the noise floor nor any buzzing birdies on 160 thru 2m. An external thermostat adapter was installed, and on the cable to the thermostat I did apply a proper choke, just in case. All AC wiring is in Sealtite or EMT conduit. Exact models are MSZ-GL12NA-U1 - indoor. MUZ-GL12NA-U2 - outdoor. -Gary NA6O > > Does anyone have suggestions for an RF quiet ductless, also called a "mini > split" heat pump system.

In my case, I had to press and HOLD the RX ANT button. Don't remember where I read this but it worked. Toggling this switch changes the Sub Rcvr between the main antenna and the receive antenna as the signal source. The K3 is a remarkable flexible radio. With that flexibility comes complexity at times that is hard to fathom--at least for me. On Wed, May 27, 2020 at 9:50 AM Gareth M5KVK wrote: > Great minds, Grant.

When I added my furnace, I made it part of the purchase contract that there was to be no new RFI. This makes the vendor very careful. Tell them it is a showstopper, and they will be responsible for RFI removal if RFI comes with the new purchase. Get it in writing if possible. Insist they call the manuafacturer and ask about RFI for the unit you are considering, and are there RFI kits for that unit, PRIOR to your purchase... Be careful assuming brand and model numbers will remain RFI quiet over time. Vendors change parts, and circuits, within a fixed model number all the time... What is RFI quiet today, may not be RFI quiet tomorrow... Take measurements first, before the install, and after install. Use this process: https://www.nk7z.net/sdr-rfi-survey-p1/ It is part I of III in a series on using an SDR to model your RFI environment. Perform the tests, save the results, then run them all again after install... I run a full sweep once a year here, and keep the results... Also see my March 2020 article in CQ on this subject...

As a group, ALL Amateur Operators, need to push this issue with the install of any major appliance... You may not get any satisfaction, but some will, it is a statistical game... If enough manufactures here about RFI issues, they may start to think it is harming sales, then they may well start dealing with this on a proactive basis, as opposed to the reactive basis now in place. I am pretty sure some Solar Companies are already doing this, as I got a cold call from one a few years ago in the Oregon area wanting me to come out to their assembly plant and look over a few of their systems they had set up for RFI testing! We IDed a number of RFI issues. I brought a boat load of ferrite material with me, and was able to quiet down most of the RFI issues. They took notes on the material I used, and what I did to quiet things down. I assume they either add them proactively, or add them as needed... Whatever, the outcome was positive RFI wise. I also pointed them at Mike G, and Ed H., at the ARRL labs, and I assume some discussions went on there as well. 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist ARRL Asst.

It's not a new problem. My over 30 year old Maytag washing machine with crude mechanical sequencer is a horrible RFI generator. Huge noise bursts with every motor run period. I'm glad my 35 year old heat pump is still running. It's single speed, all mechanical timing and control, and RF silent. I have no problem turning off the washing machine to operate but turning off the AC is not really an option in Arizona.

The first thing is to get the manufacturer - or the industry as a whole - to admit that there's a problem. Good luck on that one, too. We've fought that on the susceptibility-to-unwanted-pickup aspect for decades with very spotty results. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From tknorris0001 at gmail.com Wed May 27 15:32:50 2020 From: tknorris0001 at gmail.com (Tom Norris NB5Q) Date: Wed, 27 May 2020 13:32:50 -0600 Subject: [Elecraft] How to allow K3S to feed multiple logging programs on my laptop?

In general, adding correct type ferrite chokes to > the AC mains and the control lines is, in general, good starting point. My advice on this is to ALWAYS confront the issue BEFORE buying the unit/system in question. NK7Z's post at 8:45 am on May 27 outlines how we should approach the issue. Put the onus on the vendor/installer, rule out those who give a blank stare or don't want to learn or to do anything about it. And get it in writing -- if it isn't quiet, remove it and provide full refund. And if it was replacing an existing system, restore that system, also at no cost. When we insist on these provisions, the good vendors will figure out what they need to make it work, the losers will vanish. 73, Jim K9YC From KX3.2 at ColdRocksHotBrooms.com Wed May 27 15:46:52 2020 From: KX3.2 at ColdRocksHotBrooms.com (Lynn W.

In-Reply-To: References: Message-ID: Tom, I use Win4K3Suite which can reproduce K3 serial data and send it to other applications that would ordinarily expect to connect directly to the K3. Win4K3Suite works in conjunction with the free utility, com0com, a virtual comport utility to ?connect? com ports to each other. The documentation of Win4K3Suite explains how to do this. I don?t use either ACLog or SKCCLogger but if all they need is a connection to a K3, I think it has a decent chance of working for you. I use it with CWSkimmer, LOGic 9, and a home brew application. See Win4K3Suite - https://va2fsq.com/wp-content/uploads/Win4K3Suite-Documentation-v1.45.pdf com0com - http://com0com.sourceforge.net/ It might take a couple of tries to make it work but it does a good job For me. 73, Ted, W2ZK On Wed, May 27, 2020 at 3:35 PM Tom Norris NB5Q wrote: > I have K3S Serial Number 11459 and a P3 and would like to communicate with > N3FJP ACLog and SKCCLogger at the same time or one of the logging programs > and the K3 Utility.

The only problem I still have is WSJT and FLDigi fight a little for which mode the radio should be in to do a certain task. I just stop the one not being used and all is fine. He gives you 30 days free of full functionality to see if you can make it go with what you want. I haven't looked back with my station and haven't had to reconfigure my digital programs and loggers once since implementing it when switching modes. It is in my mind a software incarnation of a CI-V router for Icom radios. It has unlocked a lot of operating ease with my K3 and K3S.

If a component can be left out even if its only a few pennies it will be left out. I was in the service business and owned a business for over 25 years doing installations. I was never asked about RF noise by a customer. Ever. I did however ask factory reps questions and most looked at me with deer in the headlight faces. I have been out of the business for ten years and suspect that the situation has not improved and perhaps gotten much worse. Realistically when you see the number of active hams who buy AC products vs the number sold you will realize it a very uphill battle. Very noisy led bulbs have been sold for how long? They are a known source too. It was a conscious decision to ignore this by the government because it fit in with the energy saving mandates. Its a case of the squeaky wheel getting greased. When price is the major factor quality always suffer. You can't have both. I don't like it either. I'm in the middle of fighting with a trio of noisy inverters where I live. The RF noise is so bad it kills 2 meters and UHF. Background noise is S9 all the time. Even at night. Unless its dark and I kill the feed to the panels. The installer is no help and I don't own the building. FCC said call the manufacturer. Great. My KX3 allows a respite by going out into the field.

In-Reply-To: References: Message-ID: <03e101d634cd$7d594230$780bc690$@cox.net> John, I have been using my K3 (sometimes together with my second one) for FD at 100W for many years with excellent results. The power source is pre-charged lead acid batteries which we change as needed. Sometimes the battery in use is assisted by an ancient solar panel that probably doesn't contribute much. I would roughly say about 3 "full size" batteries are good to power one K3 and a laptop for the whole contest with no solar. The batteries have mostly been the flooded type including 12V types and pairs of 6V golf cart ones wired in series (I count the pair as two full size batteries). My yellow Optima AGM is often used as one of the 3. Starter batteries are not suitable for the deep discharges we are using. True deep cycle batteries are best. Marine batteries are ok but not as good for deep cycling as true deep cycle batteries. It is true that the K3 will work to as low as about 10.5 V, and we have often abused the batteries by letting them go down that far. We tried to check voltage often, but... Eventually one will notice when the radio isn't putting out full power etc. At that point we disconnect and hook up a new battery or 6 V pair. The low voltage performance of the K3 is so much better than some other 12V radios. The K3 is specified to require at least 11V. I have a Yaesu radio that is specified to need at least 11.73V (13.8 V - 15%). One FD we tried an FT-1000MP, which stopped working when only a small fraction of the battery capacity had been used up. With decent batteries and doing only one FD per year, the batteries survive the abuse for several years. Why do I say "abuse" when we use deep cycle batteries for our deep cycling? It is a bit of a myth in ham circles that deep cycle lead acid batteries are made to cycle to almost empty. We get away with it because FD is once a year. The RV industry knows better. Lots of people live in their RV's year around, and may cycle their batteries once a day. A good lead acid deep cycle battery (including flooded or AGM or gel cell) is made to last a few thousand "deep" cycles, but the rule is your "deep" cycle cannot ever discharge below 50% of battery capacity. I can't give good statistical data, but with our abusive but rare use I guess we probably kill a good deep cycle battery in 5 to 10 years. Of course if you make sure never to go below 11 V, you cn probaly get hundreds of cycles. Very roughly I would guess we draw about 200 Ah out of the 3 batteries for the whole contest. Now to your setup with one fully charged 100 Ah batttery and 120 W solar. Solar panels are spec'ed for lab conditions. In practice I would guess your panel delivers about 100W at peak and much less at other times of day. Over the whole day, I would expect to get maybe 500 Wh or about 40 Ah for the whole day. Then consider that a lead acid battery self-throttles the charging current when it is close to full. If in your location the maximum solar radiation occurs near the beginning of the contest, so the battery is almost full, only a small portiion to the current offerd by the solar panel can actually go into the battery, and during receive it cannot go into the rhe radio. So overall you would get much less than 40 Ah our of the solar for the whole day. The battery has 100 Ah, but if I remember correctly, that includes charge deliverable after the battery voltage has dropped a lot, such as below the level where the radio stopped operating (and you are really asking for battery damage). With a wild guess (don't ask me to justify these numbers) if you run the K3 like we do, with your setup you might have only 80 Ah available from the one battery and 20 Ah from the solar panel, for a total of 100 Ah, which is half of the 200 Ah needed. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Bill Frantz Sent: Wednesday, May 27, 2020 6:13 PM To: John Kountz Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] RE; How well does the K3 work with lower power supply voltage . . .

Good power/weight and power/size ratios and near full voltage until the end of their capacity. The down side is they are more expensive the lead-acid batteries. 73 Bill AE6JV On 5/28/20 at 8:41 PM, john at t6ee.com (John Kountz) wrote: >I have two K3 transceivers and have attempted to use them on several >Field Days with limited joy and unlimited disappointment.

In my case, I had to press and HOLD the RX ANT button. Don't remember where I read this but it worked. Toggling this switch changes the Sub Rcvr between the main antenna and the receive antenna as the signal source. The K3 is a remarkable flexible radio. With that flexibility comes complexity at times that is hard to fathom--at least for me. On Wed, May 27, 2020 at 9:50 AM Gareth M5KVK > wrote: Great minds, Grant. That's my next step.

Meaning that the two small riser modules that it plugs into are properly seated to the main RF board and the KRX3. I had a dead sub-receiver problem once. I had been in the radio at some point to install an update. When reinstalling the KRX3, I had pinched one of the coax cables that?s in the vicinity of the riser nearest the front of the radio and pulled the cable out of it?s socket when reinserting the KRX3, far enough not to work, but not so far that I noticed it until the next time I tried using the sub.

When AUX input cable of the KRX3 is connected to the KAT3, the NON-TRANSMIT antenna used for the KRX3. Only one can be physically connected to be used by the KRX3. If no ATU, the only connection that is available would be to the installed BNC AUX connection. I believe this config selection may be inserting attenuation during transmit in the KRX3 signal path to provide protection. For KRX3 AUX input I would always build / config to use the BNC connection. There are 2 points of failure in the ATU that would be catastrophic for the KRX3 if either of 2 relays fail.

I still believe KRX3 ANT= ATU is correct, but what jogged my memory Gareth is I believe, and I'll have to check, is that if you have the ATU installed with the two antenna ports you can use the non-transmit port for a receive antenna.

Well...you certainly have a mystery here. I found the documentation in the Elecraft manual on this subject a little hard to follow; the book by Fred Cady on the K3 is better and, if you'd don't have have it, I highly recommend it. I think you said on a previous post that you can hear the noise of the SUB when enabling it, then you are correct that there is something blocking the signal from the antenna. Assuming the configuration is correct, it might be the cable inside the K3 that feeds the signal to the SUB. When I opened up my K3 a while back to add a filter to the SUB. I noticed that one of the little coax cables entered the SUB at a pinched right angle (at least it was in mine). While I didn't have a problem, it seemed like it could be a problem if I didn't make sure the little connector was firmly inserted. I'm afraid I'm now beyond my pay grade on this...

Granted, this was over 40 years ago, so battery technology has obviously changed a lot since then. Basically, a pure chemical lead/acid battery cannot supply the yuge starting current required to crank over a big V8 engine, so antimony is added to the plates which drastically increases the max current rating. However, the down side is that this chemical composition battery is irrevocably damaged if it is allowed to discharge below a certain voltage. "Deep-Cycle" batteries are simply regular lead/acid batteries without the added antimony, thus allowing recoverable discharge way below that which would kill a "car" battery. They won't crank your muscle car over, but a small electric outboard boat motor is fine. Since the IMD degrades at low DC supply voltages in our typical 12V powered finals, if you must use a deep-cycle lead/acid battery, I suggest using one of those battery booster things that MFJ and probably others sell to keep the output up. 73, Charlie k3ICH From rick.nk7i at gmail.com Thu May 28 12:57:36 2020 From: rick.nk7i at gmail.com (Rick Bates, NK7I) Date: Thu, 28 May 2020 09:57:36 -0700 Subject: [Elecraft] Problems with KRX3A In-Reply-To: References: <283F240B-89EA-4E10-966F-AE0FE61F7C72@widomaker.com> Message-ID: Gareth, The information you have been given is correct but it's a challenge to wrap ones head around the details, a couple are subtle. It is ultimately the items you have installed (the tuner, with the second antenna port) AND the connection of cables to the KRX3 (which connector source is chosen), THEN the setting in menu (KRX3 = ANT | BNC) to match those choices. [The KRX3 will listen to ANT 1 | 2 with a tuner OR will listen to MAIN (whatever the main RX is using) | BNC; with or without a tuner (I think that's all inclusive).] Then, the use of the front panel to engage which feed is in play, based on the options above (ANT 1 or 2; with a tuner| Main or BNC). In my case, with a tuner (unused, one port to a KPA1500, the other to a dummy load) I chose to use the BNC as the RX source for the KRX3, simply so I cannot transmit into it, ever, and have diversity reception.? I can listen via main or BNC (RX system) and worry less about doing something stupid like blowing up the RX system and/or finals. It also means that if I want the main receiver to hear the RX antenna (but transmit on the transmit antenna) I have to move a cable on the K3 in the back (or provide a antenna switch), both are BNC, one is more challenging to reach through the maze of wires. I'm hoping from the comments, that the K4 will be simpler to configure (on the fly) as most of us need simpler as we age ;-)?? The most difficult part is deciding how one will use the tools most effectively, then put the parts in the right place to meet that/those goal/s. None of which answers your original question. I don't mean to be pedantic or insulting; I try to be complete because it's always the simplest of things that are the most elusive; details matter. Assuming that the menu is set to enable a KRX3 and both SYN are showing expected results based on which SYN is installed (you've done this): Hearing the rx audio 'rush' noise is a good start (use headphones, don't mix audio from the main RX); the audio stage is working, now look backwards. Check the KRX3 filter selection to make sure that (a) the filter (menu) choice is correct (right filter) and (b) visually confirm the presence of the filter (DOH!) and (c) is actually IN the slot chosen (menu setting again).? Nothing is automatic, you tell the firmware what and where filters are installed.? (A quick test is to change the filter bandwidth on the front panel [B SEL or speaker/headphone audio]; note any audio changes from wide to narrow, if any.) Then (if no success) I would start with actually seeing how the TMP cables are connected (you need to know anyway then change if needed to meet your goals); ARE they in the correct place; testing them along the way for continuity and shorting; then make sure that each is seated _fully_ (easy to miss) and correctly (hemostats or very small point pliers on the cable metal connector, very gently but firmly; tactile senses cranked up, damage is easy).? Do NOT ever pull on the cable itself. Recheck the menu for the correct source settings again (in particular if you made changes). If still no joy, based on your time difference to CA, an email of your test/findings to the repair team at Elecraft would be the best choice. Please post your results, good and bad so others can learn too. 73, Rick NK7I On 5/28/2020 8:54 AM, Gareth M5KVK wrote: > Thanks, Clark > I think I?m going to open her up again and test all the connecting cables. > > Never mind, at least I get to use my K2 for a change ? > > Gareth, M5KVK > > From: Clark Macaulay > Date: Thursday, 28 May 2020 at 16:47 > To: Gareth M5KVK > Cc: Mark Musick , "elecraft at mailman.qth.net" > Subject: Re: [Elecraft] Problems with KRX3A > > Hi, Gareth. > > Well...you certainly have a mystery here.

Assuming the configuration is correct, it might be the cable inside the K3 that feeds the signal to the SUB. When I opened up my K3 a while back to add a filter to the SUB. I noticed that one of the little coax cables entered the SUB at a pinched right angle (at least it was in mine). While I didn't have a problem, it seemed like it could be a problem if I didn't make sure the little connector was firmly inserted. > > I'm afraid I'm now beyond my pay grade on this... > > On Thu, May 28, 2020 at 11:36 AM Gareth M5KVK > wrote: > Thanks Mark > Sadly, Changing the CONFIG KRX3 to be ANT=ATU makes no difference. > > Gareth > > ?On 28/05/2020, 16:08, "Mark Musick" > wrote: > > HI Gareth, > Sorry, I sent my previous e-mail to you before seeing this one. > You have jogged my memory. > I still believe KRX3 ANT= ATU is correct, but what jogged my memory Gareth is I believe, and I'll have to check, is that if you have the ATU installed with the two antenna ports you can use the non-transmit port for a receive antenna.

That being so you will not have selectable ANT 1 or ANT 2. That being the case you will only have AN1 1 (the main RX/TX antenna) or the Aux RF antenna available to you for the Sub RX. You can forget all the ANT 1 or ANT 2 stuff because you don't have an ANT 2 available. With the SUB RX activated (tap SUB) and hold B SET which will then be displayed on the main display tapping the ANT button will toggle between Main and AUX. If you want the sub RX to listen on the same antenna as the main RX this should be set to MAIN. For now forget RX ANT, just make sure the RX indicator is not showing on the main display (immediately under the third digit of the main frequency display). This is the simple starting point. We are looking simply at Fig 1. Is the K3 upgraded to the new synths? Probably not, however, old or new they both, and you need two, have to be the same, not mixed. How are we doing?

If the RX icon is off, the subreceiver is sharing the main receiver?s RF source. In either case, the ANT 1 - 2 icons will show which KAT3 antenna is available for use by the subreceiver.

I'm about to make a start on pretty much the same diagnostic approach. I'll let you all know how I get on. Gareth, M5KVK ?On 28/05/2020, 18:00, "elecraft-bounces at mailman.qth.net on behalf of Rick Bates, NK7I" wrote: Gareth, The information you have been given is correct but it's a challenge to wrap ones head around the details, a couple are subtle. It is ultimately the items you have installed (the tuner, with the second antenna port) AND the connection of cables to the KRX3 (which connector source is chosen), THEN the setting in menu (KRX3 = ANT | BNC) to match those choices. [The KRX3 will listen to ANT 1 | 2 with a tuner OR will listen to MAIN (whatever the main RX is using) | BNC; with or without a tuner (I think that's all inclusive).] Then, the use of the front panel to engage which feed is in play, based on the options above (ANT 1 or 2; with a tuner| Main or BNC). In my case, with a tuner (unused, one port to a KPA1500, the other to a dummy load) I chose to use the BNC as the RX source for the KRX3, simply so I cannot transmit into it, ever, and have diversity reception. I can listen via main or BNC (RX system) and worry less about doing something stupid like blowing up the RX system and/or finals. It also means that if I want the main receiver to hear the RX antenna (but transmit on the transmit antenna) I have to move a cable on the K3 in the back (or provide a antenna switch), both are BNC, one is more challenging to reach through the maze of wires. I'm hoping from the comments, that the K4 will be simpler to configure (on the fly) as most of us need simpler as we age ;-) The most difficult part is deciding how one will use the tools most effectively, then put the parts in the right place to meet that/those goal/s. None of which answers your original question. I don't mean to be pedantic or insulting; I try to be complete because it's always the simplest of things that are the most elusive; details matter. Assuming that the menu is set to enable a KRX3 and both SYN are showing expected results based on which SYN is installed (you've done this): Hearing the rx audio 'rush' noise is a good start (use headphones, don't mix audio from the main RX); the audio stage is working, now look backwards. Check the KRX3 filter selection to make sure that (a) the filter (menu) choice is correct (right filter) and (b) visually confirm the presence of the filter (DOH!) and (c) is actually IN the slot chosen (menu setting again). Nothing is automatic, you tell the firmware what and where filters are installed. (A quick test is to change the filter bandwidth on the front panel [B SEL or speaker/headphone audio]; note any audio changes from wide to narrow, if any.) Then (if no success) I would start with actually seeing how the TMP cables are connected (you need to know anyway then change if needed to meet your goals); ARE they in the correct place; testing them along the way for continuity and shorting; then make sure that each is seated _fully_ (easy to miss) and correctly (hemostats or very small point pliers on the cable metal connector, very gently but firmly; tactile senses cranked up, damage is easy). Do NOT ever pull on the cable itself. Recheck the menu for the correct source settings again (in particular if you made changes). If still no joy, based on your time difference to CA, an email of your test/findings to the repair team at Elecraft would be the best choice. Please post your results, good and bad so others can learn too. 73, Rick NK7I On 5/28/2020 8:54 AM, Gareth M5KVK wrote: > Thanks, Clark > I think I?m going to open her up again and test all the connecting cables. > > Never mind, at least I get to use my K2 for a change ? > > Gareth, M5KVK > > From: Clark Macaulay > Date: Thursday, 28 May 2020 at 16:47 > To: Gareth M5KVK > Cc: Mark Musick , "elecraft at mailman.qth.net" > Subject: Re: [Elecraft] Problems with KRX3A > > Hi, Gareth. > > Well...you certainly have a mystery here.

Assuming the configuration is correct, it might be the cable inside the K3 that feeds the signal to the SUB. When I opened up my K3 a while back to add a filter to the SUB. I noticed that one of the little coax cables entered the SUB at a pinched right angle (at least it was in mine). While I didn't have a problem, it seemed like it could be a problem if I didn't make sure the little connector was firmly inserted. > > I'm afraid I'm now beyond my pay grade on this... > > On Thu, May 28, 2020 at 11:36 AM Gareth M5KVK > wrote: > Thanks Mark > Sadly, Changing the CONFIG KRX3 to be ANT=ATU makes no difference. > > Gareth > > ?On 28/05/2020, 16:08, "Mark Musick" > wrote: > > HI Gareth, > Sorry, I sent my previous e-mail to you before seeing this one. > You have jogged my memory. > I still believe KRX3 ANT= ATU is correct, but what jogged my memory Gareth is I believe, and I'll have to check, is that if you have the ATU installed with the two antenna ports you can use the non-transmit port for a receive antenna. In other words if you have the ATU and have ANT1 selected as the transmit antenna you can select ANT2 for receive. It may be that setting is set to ANT2 when it should be ANT1.

I have already done the minimum load resistor which helps to reduce the birdies on 80 meters. What I am referring to is a resistor change done in production which slows down the PSU fans when the amp is idle in standby. I have not had confirmation back from support on this yet. Support is sending me something today but I believe it is the load resistor which I have already done.

Maybe I missed it but I have never seen anything that says you can or cannot hear a SIGNAL in the SUB RX audio .All I have seen is you hear "noise" Forget all the ant possibilities -- Fire up your K2 so you have a S9 signal in the shack on the MAIN and see if you hear a carrier from the SUB preferably in CW or USB/LSB so there is a beat note. My K3 or K3S sub rx will hear a S9 50 uv signal on40 fed into ANT1 when SUB switched to RX (My SUB ant is on BNC) at 1uv into ANT 1 its ESP -my K3 is almost dead quiet with no ant and RF/AF wide open (AF gain LO.) I just checked and it made no difference if I switched the KRX3 to BNC or ANT Just repeated the exact same on K3S and does exactly the same. BTW when I assembled my K3 it was dead and it was a bad KXV3 module -which Elecraft replaced virtually overnight . Which reminds me seems like you have to cut some jumpers when you install a SUB dunno if the guy you bought it from did it himself or it came from factory. If you dont hear any sig from the SUB -then its back to TMP cables or Filter set up-connection or NB module pins etc .

The impedance matching is important for full power output. You are not the first to miscount the turns on a toroid (adding an extra turn). Remember that a single wire through the core is one turn and a full wrap around the core is 2 turns.

In-Reply-To: References: Message-ID: Measuring the inductance is not a good approach unless you have a way of measuring it at a specific frequency. The toroid material?s effect on the inductance of the finished coil varies with frequency, and most LC meters use a frequency below the HF range.

I also have a K3 & KX3 so I figured selling the KX2 would not hurt. Big mistake. I had the Icom for about a month and then decided to sell ? I am mostly CW and as a CW rig it was not that great (mechanical QSK relay made too much noise for one thing). After selling the Icom 7300, I bought another new KX2 Kit and enjoyed putting one together again. I am guessing this entire mistake cost me about $250 to $300.

I am experiencing a continuing and repeatable problem with my KPA-1500 on 6m. With the amp in bypass I am able to operate normally with my K3s, but the amp's meter is showing a 1.8 to 2:1 SWR on that band, despite measurements on an AA-230 analyzer and the SWR meter on the K3s itself showing it virtually flat (no more than 1.2:1). Once the amp is placed set to operate it's still showing SWR measurements of 1.8:1 to 2.1:1 consistently when delivering power. If the tuner is bypassed I can't run more than about 600W out before it faults. If I put the tuner in and click it to tune, it will deliver power just fine at 1200 or 1300 Watts for ONE FT8 transmit cycle. When it goes to transmit again it hard-faults with too much reflected power. Using 100W straight from the K3s there is no issue whatsoever, but *any* level of power from the KPA is liable to trip the excess reflected power sensor on the amp. At first I thought I had an antenna problem, but yesterday I put up a brand new 6m LFA and it's doing the same thing. This coming week I plan to replace the feedline with LMR-400--it's got a combination of 3/8" hardline and RG-213 at the moment. Any thoughts on what might be going on here?

Guys who do lots of portable setup say to always check the coax first, which mostly means check for a connector that's bad or badly installed. In general, if it doesn't say Amphenol or isn't stamped with a MIL spec number, it's very likely to be poor quality. This includes barrels, adapters, etc. Also make sure that every connector is" wrench tight." The advice to run it straight to a dummy load is right on -- if you have one big enough. :) 73, Jim K9YC From AB1DD at comcast.net Sun May 31 20:56:51 2020 From: AB1DD at comcast.net (AB1DD) Date: Sun, 31 May 2020 20:56:51 -0400 Subject: [Elecraft] KX3/KXPA100 Message-ID: Here's a question concerning using the KXPA100.

So this afternoon I replaced the feedline. I now have about 80 feet of brand new LMR-400, new 83-SP1 connectors (and an Amphenol adaptor at the balun since I don't have any type-N connectors here). The AA-230 ZOOM analyzer shows about 1.2:1 at 50.313, with resonance just below the band. I'll fix that tomorrow, but 1.2 or 1.3:1 should be nothing to the KPA. The TDR screen looks very clean, just a tiny bump where the feedline goes through the (new) bulkhead connector to get into the house. See: https://www.dropbox.com/s/izcwvece7nt5f42/2020-05-31%2019.32.44.jpg?dl=0 The SWR chart between 50.000 and 50.500: https://www.dropbox.com/s/y2xh4l1lihy2ujr/2020-05-31%2021.23.29.jpg?dl=0 Again, I know the antenna is resonant a bit low, but this should NOT be a factor. So here's what's now going on. 1) Into a Cantenna dummy load, with 25W of drive from the M3s, the KPA-1500 is delivering 1075W and showing 1.4:1. No problem delivering power and no faults. 2) With input power increased, 35W of K3s drive gives 1375W at 1.5 into the Cantenna. Again, no problem delivering power to the purely resistive load. Why a 1.5:1, I don't know, but fine, whatever. I can TX for 15-20 second periods without issue. 3) When I switch over to the live antenna, with25 Watts of drive from the K3s into the actual antenna and the amp faults out instantly in bypass. When the amplifier is in bypass and the tuner is in bypass, and when the K3s is delivering about 90W in FT8 mode, the front panel on the KPA-1500 says the SWR is 1.9:1. When I press the TUNE button on the radio, it's showing an SWR of 1.4:1. 4) Amp in bypass, tuner inline, press TUNE button on the K3s and the front panel of the KPA-1500 is showing a perfect 1.0:1 match. It SHOULD work fine like this, right? 5) Pressing ONLY the OPER/STBY button to put the amp in operate (KPA tuner in and untouched since step 4), the amp SOMETIMES delivers power, sometimes faults out, shows an SWR of 1.7:1. Pressing the OPER/STBY button again to use only exciter power, and touching NOTHING ELSE, it's back to 1.1:1 with 90W of K3s drive. 6) There is basically no rhyme or reason why this is happening and it's *somewhat* repeatable. The incredibly frustrating part is if I see a needed station come up, I'll flick the amp's tuner in line and it says it's tuned. Once WSJT-X keys the radio, 90 out of 100 times the amp will hard-fault. If it doesn't fault on the first transmission, it absolutely WILL on the second transmission. So I'm now at a complete loss to understand what's going on here. Amp is fine into a resistive load. Brand-new antenna, brand new LMR-400 feedline, brand new connectors, the KPA-1500 is faulting out the same as it did on the 10+ year old 6M5 with a patchwork of feedlines. I can't see how this is anything but a problem in the KPA-1500 (S/N 0398). - pjd -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Jim Brown Sent: Sunday, May 31, 2020 8:22 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA-1500 faulting on 6m; SWR issues On 5/31/2020 9:54 AM, Jim Miller wrote: > Have you vetted your feedline at 1500w?

Guys who do lots of portable setup say to always check the coax first, which mostly means check for a connector that's bad or badly installed. In general, if it doesn't say Amphenol or isn't stamped with a MIL spec number, it's very likely to be poor quality. This includes barrels, adapters, etc. Also make sure that every connector is" wrench tight." The advice to run it straight to a dummy load is right on -- if you have one big enough. :) 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 lists at w2irt.net From jackbrindle at me.com Sun May 31 21:38:13 2020 From: jackbrindle at me.com (Jack Brindle) Date: Sun, 31 May 2020 18:38:13 -0700 Subject: [Elecraft] NOT the feedline (was KPA-1500 faulting on 6m; SWR issues) In-Reply-To: <05fa01d637b4$2553acd0$6ffb0670$@w2irt.net> References: <05fa01d637b4$2553acd0$6ffb0670$@w2irt.net> Message-ID: <0A84EF41-DD51-48A8-B2CE-AB865FEB00D3@me.com> Balun?

FYI it reads 1.2:1 in to a perfect load on 10M also, but 1.0:1 on all other bands.Elecraft have various excuses for this. 1500W its really pushing it on 6M. Way to much compression. I run mine at 1100W out with 38W drive. as you state 90W, that's way too much drive. As the amp warms up the output drops (on all bands), but I never exceed 38W drive on 6M. On FT8 I drive it to 500W out only, and the amp stays reasonably cool. On 6M I bypass the tuner as the real antenna SWR is less than 1.5:1, and I ignore what the KP1500 says it is. Try the amp the way I use it and see how it goes.

The 90W figure is with the amp IN STANDBY! I wouldn't dream of putting more than about 35W into the KPA-1500. I generally like to run about 1200W on 6m, but even if I turn my K3s drive down to 20 Watts, it will STILL hard-fault regularly. NO AMOUNT OF DRIVE from the K3s will stop these problems. If the amp is set to deliver power it's going to fault on 6m, regardless of what the ATU is set for (bypass or inline), and the KPA will miss-read the SWR of the antenna system. The resistance figure is 50.8 Ohms, and the reactance is -11 according to the AA-230. The only difference between "works reliably" and "faults out all the time" is one is a resistive-only load, the other has a reactive component. - pjd -----Original Message----- From: Paul Baldock Sent: Sunday, May 31, 2020 10:06 PM To: Peter Dougherty ; elecraft at mailman.qth.net Subject: Re: [Elecraft] NOT the feedline (was KPA-1500 faulting on 6m; SWR issues) A few things I observe on my KPA 1500: On 6m the KPA1500 reads 1.3/1.4:1 into a perfect load. FYI it reads 1.2:1 in to a perfect load on 10M also, but 1.0:1 on all other bands.Elecraft have various excuses for this. 1500W its really pushing it on 6M. Way to much compression. I run mine at 1100W out with 38W drive. as you state 90W, that's way too much drive. As the amp warms up the output drops (on all bands), but I never exceed 38W drive on 6M. On FT8 I drive it to 500W out only, and the amp stays reasonably cool. On 6M I bypass the tuner as the real antenna SWR is less than 1.5:1, and I ignore what the KP1500 says it is. Try the amp the way I use it and see how it goes.
