I made a few small baluns out of binocular cores that are 4:1, which handle the output of the KX2 on Voice, CW and digital all day long.

If we're fortunate enough to have a tree, that OCFD with a center height at 10 to 15 feet or so works perfect for NVIS, at least for us. "You'd be proud to know my KX2 has survived remote jungles, 14-er peaks in Colorado, -30 degree F temps, a helicopter crash, and gunfights / IED blasts ....

Not related to AM, but my P3/SVGA sees a LOT of very splattery SSB signals generated by low cost JA transceivers. A few weeks ago during a contest, I saw it on the signal of a local, fairly new ham, told him about it, and volunteered to help him fix it by listening and watching as he adjusted drive to his amp. Turned out it was his radio, a $1700 Yaesu FTDX3000. Splatter from these signals is often as wide on both sides of the signal as the signal itself. I measured his splatter as less than 20 dB down from his intentional signal. There's a roundtable that hangs out just above the FT8 slot on 160; most of the radios are clean, but there's usually one or two that splatters down into FT8. 73, Jim K9YC From ockmrzr at gmail.com Mon Mar 2 12:19:58 2020 From: ockmrzr at gmail.com (ockmrzr at gmail.com) Date: Mon, 2 Mar 2020 10:19:58 -0700 Subject: [Elecraft] Comments from Special Forces personnel on KX2 use In-Reply-To: References: Message-ID: <47dc01d5f0b6$cd766460$68632d20$@gmail.com> As we Vets say, F**K'n-A! 73 de Bruce, N7TY Yuma, AZ www.qsl.net/n7ty -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Wayne Burdick Sent: 2 March, 2020 07:53 To: Elecraft Reflector Subject: [Elecraft] Comments from Special Forces personnel on KX2 use Hi all, I forwarded a few questions from HF Pack list members to a Special Forces commander whose unit has been using KX2s in the field for three years.

I'm somewhat constrained by our HOA's Architectural Review Committee [OK, nothing visible].? My 135' end-fed wire along the wooden fence works surprisingly well at 100 W considering it is just about eye level all the way.? As good as 5 over 5 over 5 at 100' on 40?? Not quite, but I can make Q's on any open band anytime I want including DXpeditions where I wait a few days until the bruhaha has settled down some. Antennas are one of the last radio neighborhoods for the average ham to experiment with, homebrew transmitters and receivers are rare these days.? It often could take less time to just "try something" as an antenna than it takes for the endless arguments on email lists on what works and how well. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 3/2/2020 6:52 AM, Wayne Burdick wrote: > Hi all, > > I forwarded a few questions from HF Pack list members to a Special Forces commander whose unit has been using KX2s in the field for three years.

The problem is matching the feedpoint to the feedline. If you want to use coax for the feedline, you must provide a proper matching network at the antenna (balun or otherwise). Open wire line can be used with a matching network in the shack. If you are transmitting at 100 watts (or 10), all that power will go into the radiator and be radiated. If you are concerned about how effective that radiation will be consult the antenna books and look at the elevation and azimuth radiation patterns to obtain your answers. L.B. Cebik (SK) did a lot of antenna radiation models. 73, Don W3FPR On 3/2/2020 2:13 PM, Fred Jensen wrote: > Folks these days seem to be looking for the perfect [magic?] antenna and > are reluctant to just try a basic "non-buried conductor" unless it comes > with the magic guarantee first.?

The guy who said it was Riley Hollingsworth, who almost single-handedly cleaned up the ham bands before retiring 8-10 years ago. I personally have no problem with wider bandwidth IF it's not practiced on crowded bands. At this low part of the solar cycle, bands like 40 and 20 phone bands are pretty packed when they're open, and prop on the higher bands mostly stinks. :) Wider bandwidth can certainly work in the Extra segment of 75 and the upper part of 160. 73, Jim K9YC From 99sunset at gmail.com Mon Mar 2 18:03:18 2020 From: 99sunset at gmail.com (Steve Hall) Date: Mon, 2 Mar 2020 18:03:18 -0500 Subject: [Elecraft] Elecraft 40 meter SSB net Message-ID: We held the first 40 meter net Sunday on 7.282 at 1845Z.

Amateur radio is a hobby comprised of experimenters, home-brewers, DXers, contesters, ragchewers, CW enthusiasts and EM comms to name a few. Each group has their own technical needs. Regarding AM in transceivers, it hasn?t been properly implemented for the last 50 years or more. It is a derivative based on SSB generation which introduces many shortcomings with the worst being steep skirted SSB filters. I?ve worked professionally with AM broadcast transmitters since 1958 and watched them evolve over the decades as we perfected the science over that time. I?ve worked with LW and MW transmitters to 2 megawatts and shortwave to 500 kilowatts over the years and consulted on design with almost every major TX manufacturer. One of the basics is that a transmitter should have an audio bandwidth 2 to 3 times the actual transmitted audio bandwidth. Bandwidth and peak control is then external to the TX. Lack of that capability is part of the reason some transceivers sound bad on AM. It is also the source of part of how some hold AM in low esteem due IM and other distortions in the linear amplification chain, again, due to a predominately SSB oriented design. There are a number of modified BC TXs mostly on 160 and 80 meters with audio bandwidths between 10 and 20 KHz and they dont have the same issues but they do have proper audio processing feeding them. Back in the 1950s when AM still ruled the ham bands transmitters did not have the same issues as they were designed for AM and CW operation and did not have audio filtering even though there were more hams back then. Spectral distribution of speech have frequencies around 5 KHz20 to 30 db below speech fundamentals so the impact is not what many might think when the TX is otherwise clean. Bottom line, AM in transceivers is a compromise that takes a back seat to SSB.

Surely one can't add more wine or the glass will overflow. Then the solution is to take a drink of wine, thus reduce the amount of wine in the glass. Same for boosting in audio. The system has a point where it is full and will overflow.

I have cancelled that idea. I am looking at the FTDX101MP now. It is expensive, but available locally here in VK, and seems to have excellent specs. I did look at the K4 which I think with ATU and our taxes, would be about $8389.84 imported into Australia, and probably in a year or so regarding the waiting list. The FTDX101MP (200w) is $6K locally. I was going to ask if a 200w version may be optional for the K4, but I think that would not be popular for the USA market. Thankyou again.

Almost 100 years ago, Bell Labs, the premier engineering entity on the planet, published extensive research showing that audio frequencies below 400 Hz contribute almost nothing to speech intelligibility, but can waste 2-3 dB of transmitter power. As I'm sure you know, losing 3 dB is equivalent to reducing the effective power of our rig or amp by half! 30-40 years ago, I was working with broadcasters using multiband processing systems. I too am a retired professional in the field of pro audio, where I made my living designing high quality sound systems for public spaces. One of my specialties was designing systems for acoustically difficult spaces, and a long established "rule" for such systems was to limit audio response below 500 Hz. By contrast, the "rule" you cite is aimed at "pleasing" audio, NOT speech intelligibility. I've always set my TXEQ for max cut of the 50, 100, and 200 Hz band, 6 dB cut of the 400 Hz band, a few dB peak of the top two bands, then set COMP for indicated 10 dB gain reduction on peaks. I do lots of contesting and some DXing, and consistently get very good audio reports. Think of it this way -- improving signal to noise ratio makes audio easier to listen to, far more that transmitting excessive bass and losing that power. 73, Jim K9YC On 3/2/2020 6:01 PM, W2xj wrote: > There is an old rule that the product of the lowest and highest audio frequencies should be between 450,000 and 500,000 (depending on which ?expert? you ask).

Yes, no updates since the last update... on January 15th 2020. You can pound on your F5 / page reload key a few times to see if your browser has an older cached version of the content. If no update... then you have the latest update. 2. If you think there is a rogue / secret video that has been posted and not announced, I would suggest a YouTube search for the term 'Elecraft K4' sorted by latest video uploads: https://www.youtube.com/results?search_query=elecraft+k4&sp=CAI%253D Nope, no new videos that I haven't seen. I guess there are no new updates posted on YouTube. 3. Or maybe one could go all NSA and be super sneaky, and look for a super duper secret directory on the ftp://ftp.elecraft.com/K4/ (ftp) server... nope nothing new about the K4, other than the original brochure... woe is me! (the brochure is a pdf file there which might bring to life the thread about getting text out of a PDF file.. for the love of Elecraft, let's hope not!) 4. We could speculate on how long this thread will live... 10 responses? 20? 30? 40? I'm all a twitter thinking about how long it will last. ;) All in good fun! :) mg NG7M On Tue, Mar 3, 2020 at 2:04 PM Wes wrote: > They will deliver before FD.

But start with your audio.? Are the settings normal (comp, mic gain etc)? Can you try another microphone and turn on the monitor function to hear what your mic is producing?? Is the two-tone function accidentally on? What power output can you read when not using the amp and going above 12 watts?? If more than 12 watts, a calibrate output would be in order for for your confidence. Is it confined to one band? If you don't get direction of the cause from these tests, a phone call to Elecraft service is in order. 73, Rick NK7I On 3/3/2020 10:48 PM, Tony wrote: > All: > > I've noticed an unusual thing happen with my K3S and KPA500 amplifier > while in SSB mode.

There is no other way to get SSB audio into the K2. OTOH, if the WAV file is for keying the Winkeyer in CW mode, that would be a question to be directed at K1EL - I did not think you could create CW from a WAV file, but if possible it would have to be done in the WinKeyer - it is not a K2 consideration. A BTW note - I hope you are plugging that USB to serial adapter directly into the K2 AUX IO connector.? You MUST use the special cable for the K2 to PC.? Plugging a full RS232 port into the K2 AUX IO connector may cause damage to the K2 and will cause strange behaviors.? Only 3 pins of the K2 connector are RS-232.? The remaining ones are internal K2 signal lines to be used for communicating with external Elecraft gear such as the transverters, the KAT100, and KRC2. 73, Don W3FPR On 3/4/2020 4:34 PM, Mike Kopacki wrote: > The WinKeyer is connected to the USB port on the tablet.

Audio is also clean with no distortion. After further testing, I found that the power drop is only momentary. The RF output on the KPA500 does drop when the drive on the K3S is increased from 12 to 13 watts, but it quickly rebounds to it's normal output a few seconds later. This happens on all bands and only takes place during the transition from 12 to 13 watts. I can hear a relay click during the 12 to 13 watt increase which happens to coincide with the momentary condition described above. Whatever it is, something changes the way the transmitter behaves momentarily during that specific power change and my guess is that it's not unique to my K3S. I spend most of my time on CW and little on SSB so I never noticed this before. Other than that, the K3S and KPA500 work flawlessly.

If the K3S has normal output when you're not adjusting the power out, I wouldn't worry about it. If the K3S in CW is set for the desired power output, phone will be also. 73, Rick NK7I On 3/4/2020 6:20 PM, Tony wrote: > Rick Et al: > > The K3S makes 110 watts measured so the rigs finals appear to be just > fine.

I suspect an understanding gap here. What you're describing implies a severe mismatch AT THE ANTENNA. A mismatched load (the antenna) is transformed by the transmission line to an entirely different impedance at every point along the line. The mismatch establishes standing waves on the line, and SWR is one measurement of that, BUT -- loss in the line causes SWR to gradually get smaller along the line, reaching its lowest value at the transmitter. Computing programs like SimSmith and AC6LA's Excel spreadsheets can take measured data from analyzers that are capable of producing suitable files, and, if you know the cable's characteristics, can transform a measurement made in the shack to the impedance of the antenna itself. Radiation resistance has meaning ONLY at the antenna feedpoint, and it's a characteristic of the antenna itself. It represents power that is radiated by the antenna. IF we could connect the analzyer at the feedpoint, we would measure its feedpoint impedance, Rs +jXs, but Rs is NOT necessarily the radiation resistance. A study of texts like the ARRL Antenna Book (or equivalent in VK-land) are in order. There's a bit of a tutorial in slide show form on my website that might get you started on understanding on the transmission line part of it. http://k9yc.com/PacificonSmithChart.pdf The Smith Chart is a graphical means of understanding (and computing) what happens on a transmission line. 73, Jim K9YC From donwilh at embarqmail.com Wed Mar 4 22:58:58 2020 From: donwilh at embarqmail.com (Don Wilhelm) Date: Wed, 4 Mar 2020 22:58:58 -0500 Subject: [Elecraft] Unusual Behavior K3S / KPA500 Drive Power Greater Than 12 watts In-Reply-To: References: <0443793a-7456-413c-558d-0f593d7e4afe@optonline.net> <8a5616bd-e2c6-d148-bb16-56102c3e8b2e@gmail.com> Message-ID: <09d76b57-ec1b-e2e2-31a7-0fbc54552a09@embarqmail.com> Tony, The other comments are correct, but I will add one more. Adjust the SSB audio so that you have 5 to 7 bars on the ALC meter when talking into the mic. If you have less than that, the K3/K3S will "Power Hunt" trying to keep up with the requested power. 73, Don W3FPR On 3/4/2020 9:20 PM, Tony wrote: > Rick Et al: > > The K3S makes 110 watts measured so the rigs finals appear to be just > fine.

My feedline is only 12 feet from kx3 to the lower corner feedpoint on my 80m FW delta loop outside the window, which has a male bnc termination. I can work on it with a step ladder, it is only 16ft of the ground. The antenna high apex is at 70 ft in a tree out the front. I measured my band impedance at the antenna itself which is direct fed with coax and using a good coax choke balun. It varied from 1.3:1 at 80m to 3:1 at 20m and 1.4:1 at 6m, with other bands within those points. When I say radiation resistance I include the small copper resistance also, which is negligible on this heavy copper wire delta loop. My observation is that the band with the lowest real resistance at the feedpoint is the band that draws most current on my kx3 , which did have the atu engaged, again feedline loss is very low, since it is so short, and quality LMR240 bnc terminated both ends. So I do understand your correct explanation Jim, and it was good revision, however I should have explained my setup better to remove any assumptions on your part. The antenna works very well, and I have been working USA, Europe and Asia this week with it on most bands with FT8.

I suspect an understanding gap here. What you're describing implies a severe mismatch AT THE ANTENNA. A mismatched load (the antenna) is transformed by the transmission line to an entirely different impedance at every point along the line. The mismatch establishes standing waves on the line, and SWR is one measurement of that, BUT -- loss in the line causes SWR to gradually get smaller along the line, reaching its lowest value at the transmitter. Computing programs like SimSmith and AC6LA's Excel spreadsheets can take measured data from analyzers that are capable of producing suitable files, and, if you know the cable's characteristics, can transform a measurement made in the shack to the impedance of the antenna itself. Radiation resistance has meaning ONLY at the antenna feedpoint, and it's a characteristic of the antenna itself. It represents power that is radiated by the antenna. IF we could connect the analzyer at the feedpoint, we would measure its feedpoint impedance, Rs +jXs, but Rs is NOT necessarily the radiation resistance. A study of texts like the ARRL Antenna Book (or equivalent in VK-land) are in order. There's a bit of a tutorial in slide show form on my website that might get you started on understanding on the transmission line part of it. http://k9yc.com/PacificonSmithChart.pdf The Smith Chart is a graphical means of understanding (and computing) what happens on a transmission line. 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 vk4tux at gmail.com From jim at audiosystemsgroup.com Wed Mar 4 23:31:57 2020 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 4 Mar 2020 20:31:57 -0800 Subject: [Elecraft] High Current only on 20 Meters In-Reply-To: <042201d5f2a4$ac16a060$0443e120$@gmail.com> References: <8CD5839E-310A-461E-A3E3-0F37624C839E@blomand.net> <042201d5f2a4$ac16a060$0443e120$@gmail.com> Message-ID: <4aed860c-eac6-065f-7539-06fb25cf690a@audiosystemsgroup.com> On 3/4/2020 8:15 PM, Adrian wrote: > When I say radiation resistance I include the small copper resistance also, which is negligible on this heavy copper wire delta loop.

In the old days (when I went through EE), it was, indeed, related to the phase angle. With RF systems, it's the load that the antenna presents to the feedline, and it's different at every frequency. It's primary significance is how it looks to the feedline, which in turn affects loss in the line and, after being transformed by the line, whether the transmitter can put power into it. The function of an antenna tuner is to transform whatever that impedance is to something the 1) makes the output stage "happy", and 2) that the output stage can supply power to without stress on the output stage that could cause destructive failure. When "happy" has been achieved, the transmitter is delivering power to the line, but if the match between antenna and line is poor, not much of that power may get to the antenna, but be turned into heat in the transmission line. Remember I said that VSWR in a system is set by the load (the antenna) and is decreased by the loss in the line. If the line is long enough and mismatch is great enough, the VSWR eventually ends up a 1:1. I've used this example as an extreme case: a 1,000 ft spool of RG58 with a 10K ohm load would look like a perfect 50 ohm load to a transmitter at 28 MHz, the SWR would read 1:1 at the transmitter end of the line, and loss in the feedline would be huge. 73, Jim K9YC On 3/4/2020 9:57 PM, Adrian wrote: > Jim, yes in you example ' Rs + j Xs)' I was referring to Rs, which I though > was the antenna resistance, and jXs the capacitive or Inductive reactance, > of which does not > consume any power, but effects the power factor (phase shift) acting on the > real antenna resistance.

I meant to add that power factor now includes the triplen harmonics resulting from non-sinusoidal current with power systems that are mostly electronic loads. Current flows mostly in short peaks at the positive and negative peaks of the mains waveform to charge the filter capacitors in the power supply; as a result, the voltage waveform is rounded off and the current is rich in harmonics of the mains frequency, 50 or 60 Hz. Nearly all power distribution uses 3-phase wiring, and "triplen" harmonics (those whose number is divisible by 3) add in the neutral, no matter how well balanced the load between phases. This turned into a major problem roughly 50 years ago, when a very high fraction of current in these systems was delivered to electronic loads, everything from fluorescent lights to computers to anything with an AC to DC power supply. The most dangerous side effect is that triplen currents in the neutral of 3-phase systems can be almost twice the current in the phases, which can cause destructive failures in older systems, where the neutral used conductors and hardware rated for half the current in the phases! The movie "The Flaming Inferno" is based on the true story of a massive fire in a high rise that was started by that neutral current, spread through the building in vertical "riser" spaces, and that was fueled by the insulation on the cables themselves! Sometime in the last century, a major TV station almost went off the air because excessive heating of their power distribution was close to catching on fire! I attended an SBE (Society of Broadcast Engineers) meeting led by the consultant who worked with the station engineers on the problem. MAJOR changes were made to standards for mains wiring after this event, including the rating of transformers and neutral hardware to handle the peak currents and the harmonic content, conduit requirements for the wiring, and requirements for insulation on the wiring that does not contribute to flame spread and that does not produce toxic fumes.

I understand there are other factors in efficient power transfer, but I am confident above is part of the picture. As you know it's the reason capacitors were used in fluorescent light fittings with inductive ballasts for power factor correction . On my Delta loop it is great on 80m, but on 40m and up I switch in a 100pF capacitor to null the inductive reactance I see on the antenna there, reducing swr from 5.1:1 to 1.7:1 at the feedpoint. It should be better, not needing that, but not all antennas follow a resonant trend through the bands. Due to compromises etc working around buildings and structures to do the best with what you have.

The most dangerous side effect is that triplen currents in the neutral of 3-phase systems can be almost twice the current in the phases, which can cause destructive failures in older systems, where the neutral used conductors and hardware rated for half the current in the phases! The movie "The Flaming Inferno" is based on the true story of a massive fire in a high rise that was started by that neutral current, spread through the building in vertical "riser" spaces, and that was fueled by the insulation on the cables themselves!

While managing the supply chain and quickly finding alternate parts when they go obsolete or when shortages pop up has been a normal part of our production planning process for years, it has certainly become more challenging as this situation quickly evolves. We've been tracking and compensating for this on the K4 for some time. While we manufacture our radios, amps etc. here in California, the electronic components used by us and almost all other U.S. manufacturers come from both the U.S. and from suppliers all around the world. (Many are not even manufactured in the U.S.) We've been careful to source many of the major K4 items, like the flat screen display used in the K4, from other countries than China. The biggest area of concern recently has been with the passive components (resistors, caps etc) used on all of our designs. Even when purchased from U.S. suppliers, many of these parts may come from China and other offshore sources. We also have built up inventory on many critical K4 parts here (including Knobs etc.) but of course, as noted by others, it only takes a single critical part delay in the future to hold things up. We plan with alternate suppliers when possible, but even then we have to periodically scramble to source new parts for production. Fun, eh? In any case, so far we have not encountered any major show stoppers, though even prior to the current COVID scare began seeing delivery delays increasing. We'll have a much better picture on how this will impact the K4 as major component deliveries arrive at the factory over the coming weeks. Fortunately, we are busy both getting all aspects of production started and we are also working in engineering every day to add cool new features to the K4. Not much time to sleep at Elecraft these days.

In fact, as little as 100 feet of RG-58 will turn a 2:1 SWR at the far end into roughly 1.5:1 at the near end even at 14 MHz.?

I have no idea what you are talking about with the LOCK function. The lock function I'm familiar with just locks the VFO A frequency. As to the input protection circuit on the KPA500, I'm sure it is pretty robust and knowing Elecraft I wouldn't worry about it failing. Of course you don't want to hit the KPA500 with 100 Watts. I would think you would want to develop some sort of operating procedure for your shack to make sure that doesn't happen. 73, Mark, WB9CIF -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Tony Sent: Friday, March 6, 2020 06:06 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Extra Protection For KPA500?

Message-ID: "I have a KPA500 and the protection circuit works well, but I was wondering what can be done to add an extra layer of protection?" One approach is to use a micro-controller to manage the KPA500 and KPA500. However, most would rather avoid the additional complexity and the, not insignificant, development effort. My goal was to proactively protect against all the operator errors that would cause the KPA500 to trip a fault. I considered this to be a better approach than to rely on the KPA500 reactive protection. (Don't let the condition happen, rather than protect for it when it does happen). I didn't think of the project as unnecessary complexity. I saw it as a challenge to keep my brain active in retirement. All the firmware was coded while I was monitoring the bands for new DX so no operating time was wasted.

Turn CONFIG:PWR SET to Per Band and then with the AMP on, go to each band and set the proper power to drive the amp on that band. With the AMP off, you should have full range of the Power control. Yes, you need the AUX cable so the K3 knows the state of the amplifier. If you have the KAT500 as well, you will need 2 AUX cables. 73, Don W3FPR On 3/6/2020 2:07 PM, Tony wrote: > >> Tony, The Config Menu has a Per-Band power setting (PWR SET = PEr >> bAnd) that will set the power output depending on the band selected. >> If you use the Aux cable between the K3 and KPA500 is is fully >> automatic and seamless. 73 George AI4VZ > > George: > > I must be missing something because when I select PER BAND in the config > menu, there's no power setting to set. > > It doesn't display the power like TUN PWR does where the tune power is > shown within that menu item so you can adjust it. > > I have to order the AUX cable, but in the meantime I'd like to use this > setting with the K3S so any suggestions would be appreciated. > > Tony > > > ______________________________________________________________ > 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 jackbrindle at me.com Fri Mar 6 14:35:38 2020 From: jackbrindle at me.com (Jack Brindle) Date: Fri, 6 Mar 2020 11:35:38 -0800 Subject: [Elecraft] Extra Protection For KPA500?

The K3 exposes the second set of per-band power settings when it knows the KPA is attached and is in OPER mode. Of course to be able to communicate the AuxIO cable needs to connect the KPA to the K3, and the K3 needs to be set with RADIO = K3. Once all the conditions are set, tap the OPER button on the KPA to put it in OPER mode. The K3 will show a message indicating that the KPA is ready to go. You should be able to set the power level on the K3 to whatever level you need. Tapping the OPER button on the KPA will take it back to STBY and the K3?s Power level should then show the non-amplified power level. Of course, if you do not have the AuxIO cable installed, none of this magic can occur. The KPA needs to be able to talk to the K3 for our magic to happen. 73!

There are some conflicts that will cause problems. The Elecraft cables are set up properly with the appropriate pins cut that should not connect between the two devices. An alternative is to use a straight-through HD15-HD15 cable with the appropriate pins cut. Cutting them yourself is a pain, so we really don?t recommend that route. 73!

Yes, those bands also, because operator error (fatigue, excitement, rush, brain slip) WILL happen and having those QRP bands preset in the amp could save you grief.

Now, that ain't bad! Just WAIT until you get the KPA1500, then you'll have to ask "CAN that smile get ANY bigger?"? 0.1-1500 watt radio, you decide just how much to use, it just keeps playing.

The K3 exposes the second set of per-band power settings when it knows the KPA is attached and is in OPER mode. That's a neat feature, but since Elecraft frequency sensing and band-switching in their tuners and amps is so fast, I've never used an aux cable for my KAT500, KPA500 or KPA1500. 73, Jim K9YC From Gary at ka1j.com Sat Mar 7 00:02:14 2020 From: Gary at ka1j.com (Gary Smith) Date: Sat, 07 Mar 2020 00:02:14 -0500 Subject: [Elecraft] K4 news?

If parts aren't available, they will be. If the parts are not available because of a pandemic, they will be as soon as is realistic. It just takes patience when dealing with things nobody has an answer to or a timetable impossible to offer because of that. I'm looking forward to the K4D when you're able, good, & ready to release it.

Manufacturers live in the real world, and can only buy parts that are manufactured by other companies. When those other companies discontinue a part, alternative sources must be found, and that sometimes isn't easy, or the alternative is not of good quality. Many years ago, a fine US company called Ten Tec, based near Nashville, TN, developed the first solid state power amp based on Motorola output devices. After a year or two, Motorola discontinued them, they were unique parts, and Ten Tec had to discontinue the amp. I believe I remember reading that Elecraft was having this issue with parts for some of their older products. As to contacting support -- the telephone works great. 73, Jim K9YC From htodd at twofifty.com Sat Mar 7 14:04:01 2020 From: htodd at twofifty.com (Hisashi T Fujinaka) Date: Sat, 7 Mar 2020 11:04:01 -0800 (PST) Subject: [Elecraft] Where is Elecraft Support ?

Yes, and for Elecraft, that's a significant expense for a vintage product. The better mfrs, like Elecraft, do their best to stockpile parts as spares, but there's a limit to what you can do, and the sort of curve balls you've described do get thrown.

I later found it could be selected if I changed the 60 m enabled antennas to include the 40 m dipole. 73, Andy, k3wyc From dick at elecraft.com Sat Mar 7 18:40:42 2020 From: dick at elecraft.com (Dick Dievendorff) Date: Sat, 7 Mar 2020 15:40:42 -0800 Subject: [Elecraft] KAT500 antenna selection In-Reply-To: References: Message-ID: <001201d5f4d9$d173b780$745b2680$@elecraft.com> Band transition frequencies for K3, KAT500, KPA1500 are: 1500 <= BAND160 < 3000 kHz 3000 <= BAND80 < 4800 4800 <= BAND60 < 6000 6000 <= BAND40 < 9000 9000 <= BAND30 < 13000 13000 <= BAND20 < 17000 17000 <= BAND17 < 19000 19000 <= BAND15 < 23000 23000 <= BAND12 < 26000 26000 <= BAND10 < 38000 38000 <= BAND6 < 54200 KX2, KX3, and KXPA100 use a 4500 kHz transition frequency between BAND80 and BAND60. 73 de Dick, K6KR -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Andy Durbin Sent: Saturday, March 7, 2020 09:10 To: elecraft at mailman.qth.net Subject: [Elecraft] KAT500 antenna selection The KAT500 has continuous frequency coverage for saving and selecting tuning solutions and is not constrained to amateur band limits.

Message-ID: Having followed this thread, I can heartily endorse Elecraft's method of idiot-proofing K3 power control when used with the KPA500. I have tuned each band for maximum output (except 200W on 30 meters per regulations). When the amp is in standby and I key the K3, I see the output level on the amp's display. When switching to operate, I get the prescribed amplifier output. A momentary touch of the K3 PWR knob shows the drive level (17 - 25 watts, band-dependent). Technology has finally found a way to minimize blown amps during the wee hours of a contest! 73 de Ed ____________________________________________________________ Urologist Tells Men To "Fix" Their ED With This New Trick!

One other thing to consider is that you don?t want to connect all of the pins straight through from the K3 to the KPA500. There are some conflicts that will cause problems. The Elecraft cables are set up properly with the appropriate pins cut that should not connect between the two devices. An alternative is to use a straight-through HD15-HD15 cable with the appropriate pins cut. Cutting them yourself is a pain, so we really don?t recommend that route. 73!

This is the answer I received from Dick at Elecraft, the person who designed the software for the KAT500. Most likely he probably wrote it too. There was, however, a request from Eric, Elecraft CEO, when the info was sent to me and I had wanted to know if it was ok for me to pass this info around. Hi Jerry, Eric, our CEO says >>> Sure. But note that Dick does not have time available to answer questions on this as he is tied up on other work. << Thanks for asking in advance. 73, Doug So please do not ask Dick anymore about this subject. As you will see, Dick went into great detail on how the KAT500 works From: Dick Date: Fri, Dec 13, 2019 at 1:40 AM Subject: RE: Question about the KAT500 capability. To: Elecraft Support > Here is how the KAT500 storage allocation works. EEPROM storage for ATU settings is pre-allocated by frequency. I?ve called ?the storage area for the six ATU settings for a given frequency segment? a ?bin? because the word is often used in the program and documentation. Each ?bin? has room for 6 ATU settings. Each of these 6 ATU settings contains bits for the ATU relays (L, C, side, ATU bypass and ANT relays) plus an SWR measured when the ATU was bypassed. The antenna number (ANT relay bit settings) is included in the ATU setting, so we don?t need to preallocate something like 2 ATU settings for ANT1 and 2 ATU settings for ANT2 and 2 ATU settings for ANT3 in a 6-setting bin. Thus you can have 5 ATU settings for ANT 1 in the bin for 1801-1810 and one ATU setting for ANT2 in the same bin. The next bin for 1811 thru 1820 might have 3 settings for ANT2 and 2 settings for ANT3 and one empty. The most recently used ATU setting is moved to the front of the bin when you tune to that setting. When you have a ?full? bin, all 6 entries have ATU settings, and do another tune, it might push out the oldest setting. No duplicate settings are stored in any given bin. There is bin storage pre-allocated for all frequencies between 1.501 and 60 MHz. We have MARS, CAP, and a few other commercial/military customers. We didn?t know ahead of time what the frequencies would be for all these customers. MARS customers aren?t always allowed to tell us the exact frequencies they use. So we allocated storage assuming a continuous range between 1.5 and 60 MHz. The ATU isn?t a transmitter, we aren?t constrained to the ham bands. For 80 meters the ?bin width? is 20 kHz. Bin 1 is 3001 thru 3020 kHz Bin 2 is 3021 thru 3040 Bin 3 is 3041 thru 3060, etc. The 80 meter ham band is 500 kHz wide (3500-4000). At 20 kHz per bin, there are 25 ?bins? for the 80 meter ham band. 3481-3500 one bin, 6 ATU settings. 3501-3520 one bin, 6 ATU settings 3521-3540 one bin, 6 ATU settings. The ATU overall from 1.5 to 60 MHz has room for 1530 ?bins? each containing up to 6 ATU settings. That?s just over 12,000 ATU settings. But most of these are outside the ham bands. Here?s an excerpt from a planning spreadsheet: Our ?160 meter band? goes from 1501 through 3000 kHz, 80 meters goes from 3001 through 4800, etc. The frequencies ranges and band names match the K3.

In-Reply-To: References: Message-ID: Well there is one exception to the idiot-proofing and that occurrs if you use macros that have the PCxxx command in them for setting power.? Under certain conditions if a PCxxx command is used in a macro it can overide the CONFIG:PWR SET Per bAnd setting.? I have removed all PCxxx commands from my macros until I understand this completely and have tested each macro. I got the following from Elecraft Support and have been testing each macro to determine if the PCxxx command creates a problem. Nothing replaces the Mark1 eyeball to verify, de Dave K5MWR Power Set/Per Band is activated at the time of a band change. If your macro runs after the band change, the macro dominates--and vice versa. (The last one rules, in other words). Similarly, if the amplifier changes from STBY to OPER after the macro runs, the power will change to the stored OPER power level. Note that it is likely that if your macro sets a power level, that level will become the new default power for either the K3's STBY or OPER transmit level, depending upon which mode the K3/amplifier is at the time the macro runs. To use even more words (hi), if the amp is in OPER on 20m and you run a macro setting TX power to 75W, that will be the stored power level--whether you transmit or not. The next time the K3 is on 20m and the amplifier is switched to OPER mode, the K3 will return to that last-used AMP = OPER mode power level of 75 W. (And the amp will throw an overdrive fault when you transmit).

In the short term, however, it has caused problems when working voice. Specifically I was getting feedback if I raised the line out level on the PC too far past a certain threshold which seem to depend on the K3 compressor settings (in case you are wondering, yes, the K3 monitor level was set to 0). Despite these problems, I was able to make some 40 meter SSB contacts Sunday morning during the ARRL DX Phone contest. On Sunday afternoon, I connected to the remote with about ten minutes to go in the contest and heard PY0F calling CQ on 20 meters with a very loud signal. Not having touched the settings from the night before, I figured I would tweak the tuning on the KAT-500 and then just call him. Things did not go well. The rig broke into audio feedback and I lost transmit/receive control for what seemed like a forever, but was probably in reality only about 15 seconds. After I regained control of the rig, I power cycled the rig and then power cycled the computer (I can do that remotely). The K3 still works fine on CW, but I can no longer operate SSB. TeamViewer indicates I am getting audio to the remote site, but the radio no longer responds. I've tried both VOX and manually switching to transmit. Either way, I get nothing. I even tried playing a local audio source on the computer at the remote site which should have gone straight into the K3. I still got nothing. IS IT POSSIBLE TO DAMAGE THE LINE INPUT OF THE K3 IF IT IS OVERDRIVEN BY A SOUNDCARD LINE OUTPUT OR DOES THE K3 SOMEHOW SELF-PROTECT? IF THE FORMER, WHAT PART IN THE K3 SERVES AS THE "FUSE"? I know it is premature to assume the K3 is damaged as I haven't physically been to the remote site test the rig since the incident, but I wanted to understand what the worst-case scenarios might look like.

In-Reply-To: References: Message-ID: "Well there is one exception to the idiot-proofing and that occurrs if you use macros that have the PCxxx command in them for setting power. Under certain conditions if a PCxxx command is used in a macro it can overide the CONFIG:PWR SET Per bAnd setting. I have removed all PCxxx commands from my macros until I understand this completely and have tested each macro." That vulnerability probably also exists for a power command sent by an external application. An external controller can never be as fast as the AUX Bus link but it can react fairly quickly. In this example I forced my TS-590S to well above the coded band max power limit using DXLab Commander. My controller disabled the KAT500 key line, forced my TS-590 back to band power limit and, when band limit power was confirmed, my controller re-enabled the key line.

What are you going to make a "Lifetime Buy" on?? A synth?? A front panel?? A tuner?? You might as well buy a second (or third) rig since you don't have a clue what might fail in the future, and if you buy all those things separately (or worse yet the individual components that go into them) you better plan on working an extra year or so before retiring. By the way, I spent my career in the semiconductor business (operations manager) and I can say with great authority that many discontinued devices had no business being offered for sale in the first place.? Companies (not just mine) would often develop a new product line and bin sort for different ranges of performance. Component A might have a 30% yield but have better specs than Component B that had a 90+% yield.? Component A would get designed into more demanding applications and sell for a higher price, while Component B was higher volume, sold for less, and essentially subsidized the yields for Component A.? That worked fine until somebody decided they wanted a LOT of Component A, or the demand for Component B dried up.? No matter what anyone says, the market won't simply bail you out by paying you three times more money for Component A when you get in trouble, and after a while you have no choice but to announce a discontinuance.? I strongly suspect that's what happened to the tight tolerance caps Elecraft used in the K1 band modules. When I was the ops manager, I tried my best to squash that kind of practice.? Either make the process capable or face reality. 73, Dave ? AB7E > > ?

I send him email and he replied that he had K3. Yesterday I was calling D2EB on 3521 and got lots of angry reports about my signal jamming everything around. One station sent a panadapter screen. There are spurs about every 700 Hz. The first one is -15db from the main signal, the second -25db, and 3 KHz away it is -35 db. I checked the radio later with a SDR. It had spurs but not as big. I checked the radio today, and the spurs seem almost gone. My K3 is #2283.

A soundcard failure may have applied DC voltage to the K3 and damaged it (but I have never heard of that happening). You may have a soundcard failure of some sort and no audio is getting to the K3 - so go to the site with another soundcard in hand to use if necessary. When testing with the new soundcard, if the Line In does not work, lower the computer output of the soundcard and try Mic In (change the MIC SEL menu). If that gets audio to the K3 while Line In does not, then contact support at elecraft.com to see where you should go from that point. 73, Don W3FPR On 3/9/2020 7:50 PM, Michael Tope wrote: > Recently I've made some configuration changes at my remote station that > should in the end improve things.

I wrote some code to tell my radio and the KAT500 to walk over the bins and my antennas and essentially "push" autotune. It worked OK but not great and I think I see why now. This is a simple scheme and simple is good.. I'm not sure how much flash or EEPROM is available [1]. I can imagine some slightly more complex but space efficient and MCU-friendly data structure that could store more per frequency and per antenna granularity on an as needed basis that also spreads the LRU eviction behavior over the entire data store for least user impact.

Our government is so stupid that she did not greatly reduce the number of Mainland Chinese from entering Hong Kong at the beginning. Having said that, VR2 is still able to maintain a relatively low number of COVID-19 victims.? Here are what we have done: 1.? Over 95% of our population wearing surgical mask whenever practicable;2.? We try to avoid social gathering as much as we can;3. We wash our hands frequently before touch our noses and eyes. I worked in US and UK in the past and know many of you just think that only the sick man will wear mask.? VR2 people do not think so.?We learnt from painful experience from 2003 SARS and now did the above 3 items. We did not rely on our government but we do what we learnt from the past.

After setting the proper drive level for each band, I noticed that the settings I chose were lost if I turned the power up on the K3S. I thought the per-band settings might go back to their presets if I cycled the KPA500 from operate to standby and back, but that didn't work. If the per-band drive levels are easily bypassed, it defeats the whole purpose of having this option. Am I missing something?

The misconception is that there are presets and there are NOT, the K3s stores the last set power for that band/Amp Mode.? The "presets" are the last power setting the operator made either manually or via software/macro based on the amplifier mode (OPER/STBY).? IF you adjust the K3s power then you changed the "preset" for the amplifier mode/Band . Below is the response I got from Elecraft support on this issue, just substitute operator for macro, I have edited to make the point. de Dave K5MWR Power Set/Per Band is activated at the time of a band change. If your macro/*OPERATOR PWR ADJUST* runs after the band change, the macro*/OPERATOR* dominates--and vice versa. (The last one rules, in other words). Similarly, if the amplifier changes from STBY to OPER after the macro*/OPERATOR* runs, the power will change to the stored OPER power level. Note that it is likely that if your macro*/OPERATOR* sets a power level, that level will become the new default power for either the K3's STBY or OPER transmit level, depending upon which mode the K3/amplifier is at the time the macro*/OPERATOR* runs. To use even more words (hi), if the amp is in OPER on 20m and you run a macro*/OPERATOR* setting TX power to 75W, that will be the stored power level--whether you transmit or not. The next time the K3 is on 20m and the amplifier is switched to OPER mode, the K3 will return to that last-used AMP = OPER mode power level of 75 W. (And the amp will throw an overdrive fault when you transmit).

If one has it correct....... then changing it would seem to make it no longer correct.? This makes no sense to me. In my case, 18 to 25 watts, depending on band, is the value of power used to drive the amp to 500 watts rated output.?? Except for 30M where power value is 10 watts to comply with the 200 watt band power limitation.?? In either case, I see no reason to increase drive power as this would most likely overdrive the amp.??

If one has it correct....... then changing it would seem to make it no longer correct. This makes no sense to me." Your concept seems to be that the correct power is maximum power. What ever happened to the idea of using minimum power required to make the QSO? I seldom want to use maximum power for FT8 mode but, yes, sometimes I do. Because I work a lot of FT8 I coded a separate set of power settings for that mode. These setting are invoked when my option "Set FT8 power" is enabled. I can turn up the wick if I need to but it won't change the stored FT8 power settings or the stored band max power settings. 73, Andy, k3wyc From rcrgs at verizon.net Thu Mar 12 15:29:59 2020 From: rcrgs at verizon.net (Robert G Strickland) Date: Thu, 12 Mar 2020 19:29:59 +0000 Subject: [Elecraft] test References: <037ab481-f056-89f4-69a8-4fe5abc2dcce.ref@verizon.net> Message-ID: <037ab481-f056-89f4-69a8-4fe5abc2dcce@verizon.net> -- Robert G Strickland, PhD ABPH - KE2WY rcrgs at verizon.net.usa Syracuse, New York, USA From kevinr at coho.net Thu Mar 12 18:51:31 2020 From: kevinr at coho.net (kevinr) Date: Thu, 12 Mar 2020 15:51:31 -0700 Subject: [Elecraft] Elecraft email from 2000 onward Message-ID: <10f4bd3d-c51b-55f9-ec88-4640f810c7af@coho.net> I was digging in my computer backup files and found some Elecraft email.?

Wayne is awfully busy on other projects. We would not want to have fixed-in-firmware drive limits - KPA500s vary in their needed drive level. Some need more power than others for drive. For example my older KPA500 (actually the first one) needs 35 to 40 watts to drive it to 500 watts, while my new one needs only 20 watts. Also, the same limit may not apply to the KPA1500 (which needs more drive power). Once you set the drive level for each band you will only need to change it when you change the output power because of mode or something else that causes you to limit your output power. I rarely change mine at all. Try it and I think you will see it works very well as it is now. 73!

My son gets piles of dead laptop batteries from a computer shop. Most of the 18650 cells are quite good. He screens for capacity and discards any under 2Ahr capacity. He made a bulk charger for the individual cells, using cheaper than dirt single cell chargers and cell holders from Ebay. I think it does 20 at a time, and now has dozens ready to work. He buys hardware on Ebay that can be used to make up packs of any configuration. Subsequent charging can be done by wiring a pigtail to connect the same chargers to the cells in the pack. Obviously this requires some bench work, but once set up it's pretty efficient. There's plenty of RC model activity in VK. Airplane packs are available in a wide range of voltage and current capability, as are chargers. This is likely the best commercial source.

However, writing the code is only a small part of making any change. If the user took responsibility for setting appropriate OPER mode power levels for each band then the only changes to the firmware would be: 1. Don't allow anything (macro, serial command, power set control) to exceed that pre-defined power by more than a pre-defined percentage. 2. Don't save any power adjustment to power memory unless an overt action is taken. (Perhaps user has to unlock power settings). Neither of these changes would have any impact on users who like the way it works now.

Yes, if you want directivity.

I have made a number of presentations to ham groups on the design and construction process involved in getting the most bang for the buck, depending on your wants and needs (everybody's are different). In my own situation (2 acre semi-rural lot approx.150 feet x 600 feet running E-W feet, and active HOA) the goal was to have a single antenna that would provide the best primary signal on 80 meters in a North-South direction, while providing the best possible signal on 40 meters in an East-West direction, consistent with the 80 meter performance and without unduly provoking the HOA (or my XYL). I decided on an Extended Double Zepp, cut for 3.5 MHz. That resulted in a length of 360 feet, which worked nicely since I have 400 feet clear from the house (West end) to a perfect tree for the far East end. And another tree in the center for support of both the antenna and the feedline. I am feeding it with a 160 foot length of 600 ohm "true ladder line." I can go into more detail if this sounds like something that would work. Modeling this antenna with EZ NEC shows a maximum theoretical gain of 4.7 dbi in both North and South directions. With the ladder line, a dual hybrid balun and short length of coax into the shack, my KAT500 tunes it very nicely on all bands 160 m thru 6m. I don't have your call so can't see where you are, but would be happy to make other suggestions based on the coverage you seek. 73 Lyn, W0LEN -----Original Message----- From: bw_dw at fastmail.fm [mailto:bw_dw at fastmail.fm] Sent: Friday, March 13, 2020 11:52 AM To: Lyn Norstad; elecraft at mailman.qth.net Subject: Re: [Elecraft] Off-Topic: Your advice/suggestion about antenna Hi Lyn - thanks for the reply!

The antenna is THE most important element of any station (the accepted maxim is it's 90% of the budget but most hams are 'cheap').? The radio is useless without a decent antenna.? An EDZ can work well but the peaks and nulls vary on every band and wind in the trees can be an issue.? Height matters, a LOT too. I also hid (in plain sight) a similar 370' EDZ (at 35') antenna IN the HOA space (shot a wire over some oak trees) for years without it being seen and it worked well (other than the noise floor was obscenely high, all the time because it was urban).? It absolutely ROCKED on 40M (the noise precluded hearing much on 160M but I got 15-20 countries). If budget is less of a concern, you might want to consider SteppIR, starting with the 2 element Urban beam (40-6M).? The only other comment along that line is leave a LOT of headroom capacity when selecting a rotator, they take a lot of wind abuse.? There are other beam antennas worth consideration, many are less expensive. When I moved away from the HOA infestation area into rural with a 40 db (average) lower noise floor, in time I went from all band (R7, dipole or vertical) wires to a SteppIR DB36/80 (80-6M) which gave me an average of another 10 dB of GAIN in reception (plus directivity to null noise even further AND transmit gain too). I bought the antenna, rotor and tower at an estate sale (SK sale), saving many thousands of dollars.? The son (a non-ham) just wanted it all gone, I assisted ;-) so keep watch, ready to 'attack'. The sole remaining wire is an Inverted L for 160M.? I greatly prefer this to any dipole because the one wire is not pulled/stretched between multiple trees when it's windy (and the trees NEVER sway in sync at the same moments).? It moves precisely WITH the tree motion, it isn't stretched or pulled.? However, it's moderately deaf on 160M, I'll have to add an RX array (RBOG or 8 square are the current considerations) yet I'm now at 131 countries worked on 160M. The sole sticking point remaining is my requirement that NOTHING antenna can be seen from the house (I bought an amazing view, it came with a house), so even with the acres I have, I'm limited to a few acres total, further reduced by proximity to the power lines along the road.? Fortunately my neighbor (700' away) is also an HF active ham with even more acres (same visual rule) so we're considering a shared RX array (SDR and wifi based, which removes much of the desense issue too). So my suggestion is that you look at the larger picture and perhaps even start fresh, not re-modify the original plans (make it a Revolution, not just an evolution).? Part of my move (escape to) here was just for that reason, to start with a fresh station based on simplicity of operation (which takes a LOT of planning and work to obtain; in a couple years, it'll be there, I hope.)

And since cost is an issue for some of us (along with HOA restrictions), I rejected the idea of getting a couple extra dbi at the cost of many thousands of dollars. And adding a N-S 40m dipole fed at the same point would have required either traversing my neighbor?s yard, or erecting a 2 towers ? neither of which is feasible. And forget the logistics of erecting a 2 element beam for 80 meters (see OptiBeam OB2-80+ with 74 foot elements on a 36 foot boom), tower and rotor for that monster. We have a commercial (HST) shortwave station a few miles away that runs a 20kw transmitter on various 7 - 10 MHz frequencies into an 18 dbi gain "curtain" antenna aimed over the pole to Europe. Their beam width is 38?. Ten curtains could be hung using relatively inexpensive towers or masts spaced at 36? in a circle. The 20kw input results in an ERP of 808 KW, according to their FCC license, at an extremely low angle of radiation, and very low maintenance. That would actually be my first choice. 73 Lyn, W0LEN -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of David Gilbert Sent: Friday, March 13, 2020 1:39 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Off-Topic: Your advice/suggestion about antenna That is certainly a perfectly viable antenna and probably a fine choice for your needs ... but it does not "far outperform" either a dipole or especially a 2 element yagi at the same height.

It depends on what you want to achieve. The antenna you describe is a very old and well accepted design. It's like a beam with a fixed direction. No question that 2.6 dB can matter under marginal conditions. I have a 2-el wire 80M Yagi fixed on about 45 deg az that I can reverse to VK/ZL, which modeling shows gives me about that directivity. HOWEVER -- in this applications note, I showed that raising a 40M or 20M dipole by 15 feet will also increase gain at low angles by about 2.6 dB. See Figs 33 and 41, and the associated text. Doing this uses height to modify directivity in the vertical plane, without narrowing the horizontal beamwidth. http://k9yc.com/AntennaPlanning.pdf In the same app note, I also showed that mounting an HF vertical on a roof reduces ground losses and increases gain at lower vertical angles (below 30-40 degrees) than ground-mounting it. The differences show up for all soil conditions (except sea water), but are most pronounced for poor soil. I showed that the gain of vertical antennas is strongly affected by soil conductivity, while horizontal antennas are not, but are strongly affected by mounting height. And finally, I disproved the myth that antennas must be low for NVIS, that 75 electrical degrees is optimum, and that raising it to 120 degrees reduces high angle radiation by only 1 dB while increasing low angle radiation by 6 dB. Antennas are the component of our stations that are most strongly dependent on operator goals, real estate, the availability (and the cost) of suitable skyhooks or towers, their ability to reject local noise, and restrictions like HOAs, neighbors, and XYLs. No single antenna is best for all stations or operators. Antennas I can rig here in my redwood forest would be impossible on the city lot I owned in Chicago. :) 73, Jim K9YC From Lyn at LNAINC.com Fri Mar 13 18:05:09 2020 From: Lyn at LNAINC.com (Lyn Norstad) Date: Fri, 13 Mar 2020 17:05:09 -0500 Subject: [Elecraft] Off-Topic: Your advice/suggestion about antenna In-Reply-To: References: <046601d5f954$caf0b780$60d22680$@LNAINC.com> <04be01d5f963$eb5d81b0$c2188510$@LNAINC.com> <052601d5f970$86e5acf0$94b106d0$@LNAINC.com> Message-ID: <05c701d5f983$76732fb0$63598f10$@LNAINC.com> Jim - Your antenna research is impressive. I have downloaded the PDF and will spend some time studying it. Thanks. One question I have relates to NVIS. In the case of my 80 meter EDZ, the plan was to make it workable for NVIS operation. It has succeeded in that regard very nicely in that I can cover the entire state of Illinois (which is primarily a N-S pattern) very well on both 80 and 160. We operate a state wide ARES/RACES net on 80m, but there has been some fear that as propagation continues to worsen for a period, the MUF for NVIS will require a higher frequency than non-NVIS and one that actually approaches the MOF at that time - due to the angle of radiation. In other words, using an NVIS antenna when the MUF is 4.0 MHz might actually require an MUF of 12 - 13 MHz which would be closer to the MOF at that same point in time. Have you observed that at any extremely low spot in the cycle? We have seemingly remedied that by setting up and operating a successful 160m net and passing digital traffic. 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: Friday, March 13, 2020 4:03 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Off-Topic: Your advice/suggestion about antenna On 3/13/2020 12:49 PM, Lyn Norstad wrote: > I actually do consider 4.7 dbi as "far outperforming" 2.14 dbi (ordinary dipole). It depends on what you want to achieve. The antenna you describe is a very old and well accepted design. It's like a beam with a fixed direction. No question that 2.6 dB can matter under marginal conditions. I have a 2-el wire 80M Yagi fixed on about 45 deg az that I can reverse to VK/ZL, which modeling shows gives me about that directivity. HOWEVER -- in this applications note, I showed that raising a 40M or 20M dipole by 15 feet will also increase gain at low angles by about 2.6 dB. See Figs 33 and 41, and the associated text. Doing this uses height to modify directivity in the vertical plane, without narrowing the horizontal beamwidth. http://k9yc.com/AntennaPlanning.pdf In the same app note, I also showed that mounting an HF vertical on a roof reduces ground losses and increases gain at lower vertical angles (below 30-40 degrees) than ground-mounting it. The differences show up for all soil conditions (except sea water), but are most pronounced for poor soil. I showed that the gain of vertical antennas is strongly affected by soil conductivity, while horizontal antennas are not, but are strongly affected by mounting height. And finally, I disproved the myth that antennas must be low for NVIS, that 75 electrical degrees is optimum, and that raising it to 120 degrees reduces high angle radiation by only 1 dB while increasing low angle radiation by 6 dB. Antennas are the component of our stations that are most strongly dependent on operator goals, real estate, the availability (and the cost) of suitable skyhooks or towers, their ability to reject local noise, and restrictions like HOAs, neighbors, and XYLs. No single antenna is best for all stations or operators. Antennas I can rig here in my redwood forest would be impossible on the city lot I owned in Chicago. :) 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to lyn at lnainc.com From xdavid at cis-broadband.com Fri Mar 13 19:08:00 2020 From: xdavid at cis-broadband.com (David Gilbert) Date: Fri, 13 Mar 2020 16:08:00 -0700 Subject: [Elecraft] Off-Topic: Your advice/suggestion about antenna In-Reply-To: <052601d5f970$86e5acf0$94b106d0$@LNAINC.com> References: <046601d5f954$caf0b780$60d22680$@LNAINC.com> <04be01d5f963$eb5d81b0$c2188510$@LNAINC.com> <052601d5f970$86e5acf0$94b106d0$@LNAINC.com> Message-ID: <1a0e8ffb-e351-f40b-1284-12a8b3119adb@cis-broadband.com> Lyn, A dipole over ground has considerably more than 2.14 dbi maximum gain, and since you said you had a tree in the middle I assumed (probably incorrectly) that it was enough in the middle to allow a 40m dipole to fit crossways your lot to other trees.? If that isn't the case, OK. You didn't say whether your model that gave you 4.7 dbi for the EDZ was a free space figure (and I'm too lazy to model it myself now to check), but if so yes ... there would be at least a 2.5 db benefit to the EDZ.?

I don't work nets like you do, but I do a lot of contesting, including 80 and 160M, and if you're paying attention, can teach a lot about propagation. I have several interesting observations about 160M. First, ANY horizontal wire that we can rig is electrically very low, so ground losses are high. When I first moved to NorCal in 2006, I had an 80 ft Tee vertical with a lot of radials and a dipole at about 110 ft. During contests, I switched between them a lot. The dipole rarely "won." 160M contests start at 2PM local, so our first 2.5 hours are in broad daylight. During those hours, I soon learned that, running legal limit CW, I could reliably work out to 800 miles or so on the vertical, but not even get "QRZ?" on the dipole. Clearly, there's a difference between horizontal and vertical propagation under these conditions! When that 150 dipole bit the dust in a major storm several years later, I didn't bother to restore it. In addition, the bigger stations as far east as VE3 and W8/W9 are solid copy here as early as 3:15 pm local, but are almost impossible to work. At least two reasons are at play: 1) they're using RX antennas aimed to EU for more points per QSO and for multipliers; and 2) they have noise propagated from the east, while I have mostly local noise. While I haven't really answered your question, I do suggest that you try to rig some sort of top-loaded vertical with as much of a counterpoise as you can manage. Some years ago, I put together an app note on 160M antennas and counterpoise/radial systems, all of it the summary of very good work by others. All the advice for 160 scales for 80M. Two of the more interesting ideas are K2AV's folded counterpoise and Rob Sherwood's improvised ground screen. http://k9yc.com/160MPacificon.pdf This slide deck shows what I did in Chicago. The antennas I used there are shown beginning on page 10. I found that the 80/40 loaded dipole worked on 160 as a Tee vertical (fed with vintage 75 ohm "KW twinlead), and it worked better fed as a vertical on 80 than it did fed as a dipole. Thanks to the loading coils and the length of the feedline, it was pretty easy to load on both bands. That discussion starts on page 30. My counterpoise was a wrought iron fence that ran around my front yard. :) That antenna had no problem working anyone within 800-1000 miles. http://k9yc.com/LimitedSpaceAntennasPPT.pdf 73, Jim K9YC > > One question I have relates to NVIS.

We have gone far astray from that consideration. I am trying to bring it back to 'ground zero'. As I recall, the question was about a vertical whose feedpoint was above the ground - rocky or not. Let me add some conceptual thoughts. Does anyone remember the Ground Plane vertical that was popular back in the 1960s and 1970s (and is still commonly used on VHF today)? A 1/4 wavelength vertical radiator with usually 4 1/4 wavelength radials from the base. It was often mounted on a roof, and the radials sloped downward along the roof providing a feedpoint impedance near 50 ohms as opposed to 35 ohms if the radials are perpendicular to the vertical member. That antenna has a nice low angle of radiation, which is good for far away stations. A dipole has a higher angle of radiation, and will outperform the vertical at near-in distances. A high dipole (at least 1 wavelength high) will also have equal low angle radiation to the vertical. To work effectively, the radials must be arranged symmetrically, so each pair will cancel the horizontally polarized radiation. Actually only 2 radials are required for that, but they must be arranged 180 degrees from each other. For best performance, the radials should be tuned to the center frequency of interest - just like tuning a dipole. This is what is known today as a vertical with raised (or elevated) radials. It is ground independent in contrast to a typical vertical with buried radials which is quite dependent on ground conductivity. In comparing a vertical with a dipole, remember that a good vertical has its best radiation at a low takeoff angle, while a dipole will have its best radiation at a much higher angle. Listening tests will make the dipole have much better performance when there are a lot of stations in the 400 to 800 mile radius of the station, while the vertical will 'reach out further' while suppressing the strength of the nearby signals. So all this talk about how many dBi is nonsensical unless a specific angle of radiation is being stated as well. A good vertical has better low angle radiation than a dipole, and rejects high angle signals. A dipole that is low in terms of wavelength has a high angle component of radiation. That means to me that a dipole mounted at a modest height for 160, 80, and 40 will provide local as well as moderately distant contacts easily. A proper vertical will provide more DX contacts, and weaken the receive signals for more close-in stations - it is all in the angle of radiation - how many miles does the signal travel before it is reflected by the ionosphere? It is all a matter of physics and geometry. 73, Don W3FPR From frantz at pwpconsult.com Fri Mar 13 23:13:52 2020 From: frantz at pwpconsult.com (Bill Frantz) Date: Fri, 13 Mar 2020 23:13:52 -0400 Subject: [Elecraft] Where is Elecraft Support ?

That's addressed in the app note I referenced earlier. http://k9yc.com/AntennaPlanning.pdf And this one. http://k9yc.com/43FtVertical.pdf Mounting height and soil conductivity move the lobes around AND vary the ground losses. There are many combinations that can cause a vertical to be stronger at high angles (45-60 degrees) than a low dipole. The one characteristic of verticals is that their radiation goes to zero straight up. You don't see these things clearly until you plot patterns for antennas being compared on the same graph, as I did in those links. 73, Jim K9YC on On 3/13/2020 6:44 PM, Don Wilhelm wrote: > That means to me that a dipole mounted at a modest height for 160, 80, > and 40 will provide local as well as moderately distant contacts easily. > ?A proper vertical will provide more DX contacts, and weaken the > receive signals for more close-in stations - it is all in the angle of > radiation - how many miles does the signal travel before it is reflected > by the ionosphere??

Sometimes customers were blindsided by design engineers who somehow sneaked sole sourced devices into their system (not every company had military level supply channel control), and often it was simply the case that some critical product function was not possible without using a sole sourced device.? And as you might imagine, dual sourced devices often turned into sole sourced devices when one of the suppliers decided to quit making it, or they went out of business. Before statistical control methods like Six Sigma, lots of suppliers (my company included) didn't really even have a good handle on whether they were capable of dependably making a device or not. During my early years I remember a lot of wafer fab guys "tweaking the process" on an almost daily basis in reaction to normal process variation ... which of course actually created greater oscillations in parameter values than if they had just stayed at their desks.? At my company, we literally, and I mean literally, had to reassign some older engineers in both the wafer fabs and the assembly factories because they refused to stop "tweaking" until they actually had done the work to reduce the normal process variations. 73, Dave??

You can easily reach the point of obsession with antennas, and some of the choices involve heavy expense, tons of room, tolerant neighbors and a lot of maintenance. I think the Yagi antennas are among the best choices, by their nature they concentrate strength in one direction. As a horizontal polarized antenna they are less affected by noise than vertically polarized antennas. They also heavily concentrate power in one direction, and they naturally filter out interfering signals coming from the sides. They are fun and work really well. I am a SteppIr fan and their antennas are well built and reliable. I have done wonders with a 3 element trombone version using just 100 watts in an urban location with the antenna mounted on a nine foot rooftop tower. Yagis do involve heavy wind loading and they do require a sturdy tower type base of support and a substantial rotor. Size is always better but with size also comes expense, hard work and maintenance. Looking at SteppIr, a three element Yagi is light enough to be raised by hand with a small crew of two or three people using a gin pole. The larger SteppIrs weigh around 250 lbs and you will need a boom truck. There is a lot of wind loading with Yagis and wind storms can cause a lot of damage. Your rotor needs to be pretty sturdy; even the three elements need a Tailtwister or better. You have to go really heavy duty with the big boys and that costs a lot more money. Our Mike and Key field day site sports a wide variety of Yagis. I run the GOTA station with a small three element trapped Yagi that I can support on a temporary tripod mount made out of Army surplus aluminum tubes. The 40 meter Yagi is made of wire, six elements with what looks like a 100 ft boom, erected on lines run between trees. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Rick Bates, NK7I Sent: Friday, March 13, 2020 12:02 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Off-Topic: Your advice/suggestion about antenna Duane, I agree on both points.? The antenna is THE most important element of any station (the accepted maxim is it's 90% of the budget but most hams are 'cheap').? The radio is useless without a decent antenna.? An EDZ can work well but the peaks and nulls vary on every band and wind in the trees can be an issue.? Height matters, a LOT too. I also hid (in plain sight) a similar 370' EDZ (at 35') antenna IN the HOA space (shot a wire over some oak trees) for years without it being seen and it worked well (other than the noise floor was obscenely high, all the time because it was urban).? It absolutely ROCKED on 40M (the noise precluded hearing much on 160M but I got 15-20 countries). If budget is less of a concern, you might want to consider SteppIR, starting with the 2 element Urban beam (40-6M).? The only other comment along that line is leave a LOT of headroom capacity when selecting a rotator, they take a lot of wind abuse.? There are other beam antennas worth consideration, many are less expensive. When I moved away from the HOA infestation area into rural with a 40 db (average) lower noise floor, in time I went from all band (R7, dipole or vertical) wires to a SteppIR DB36/80 (80-6M) which gave me an average of another 10 dB of GAIN in reception (plus directivity to null noise even further AND transmit gain too). I bought the antenna, rotor and tower at an estate sale (SK sale), saving many thousands of dollars.? The son (a non-ham) just wanted it all gone, I assisted ;-) so keep watch, ready to 'attack'. The sole remaining wire is an Inverted L for 160M.? I greatly prefer this to any dipole because the one wire is not pulled/stretched between multiple trees when it's windy (and the trees NEVER sway in sync at the same moments).? It moves precisely WITH the tree motion, it isn't stretched or pulled.? However, it's moderately deaf on 160M, I'll have to add an RX array (RBOG or 8 square are the current considerations) yet I'm now at 131 countries worked on 160M. The sole sticking point remaining is my requirement that NOTHING antenna can be seen from the house (I bought an amazing view, it came with a house), so even with the acres I have, I'm limited to a few acres total, further reduced by proximity to the power lines along the road. Fortunately my neighbor (700' away) is also an HF active ham with even more acres (same visual rule) so we're considering a shared RX array (SDR and wifi based, which removes much of the desense issue too). So my suggestion is that you look at the larger picture and perhaps even start fresh, not re-modify the original plans (make it a Revolution, not just an evolution).? Part of my move (escape to) here was just for that reason, to start with a fresh station based on simplicity of operation (which takes a LOT of planning and work to obtain; in a couple years, it'll be there, I hope.)

Your initial assumption is basically correct. A vertical does not have low angle radiation unless you have a perfect ground, it will then low pseudo-brewster angle which is very effective. A 1/2wl or higher 40m dipole is actually a very good antenna and 2el shorty 40 or even rotatable dipole is even better. A simple antenna model will show the gain and pattern for all of these options. GL John KK9A Duane wrote: From what I understand - solid rock below a raised vertical is not the best option for performance. With an underlying geography of many feet of solid metamorphic rock - that would probably rule out the low angle benefits of vertical antennas. Consequently, over the years, every 40m vertical I've ever put up has been out-performed by a dipole at .41 wavelength. I've also tried the DX-Half Square and vertical Delta Loop with the same results. It looks to me like my only option to outperform a 40m dipole - is a tower and (at minimum) a 2EL yagi. Would that assumption be correct?

I ran out of space before I could get it over any of the next higher limbs.? But it was about twenty feet higher near the center and wound up ten feet higher on the north end.

Physically I am experiencing a recurrence of a very nasty flu-like cold that also hit me in November (a couple weeks after my annual flu shot) and dragged on for about six weeks. I feel better if I am vertical than if I am horizontal, so am sleeping in shorter spurts and have become a very early riser. It's actually kind of fun to be roaming the house at 4 AM. Very quietly enjoying good coffee, Girl Scout cookies (complete and balanced diet ... eh?) and making hundreds of contacts worldwide in the wee hours of the day. Our church has closed all four campuses until further notice, so that means I am free from weekend video camera duties and get to enjoy the services streamed over the internet (I am at the opposite end of the chain now). I have also opted out of all my other group activities, and in fact most of them (ARES/RACES/Skywarn/etc.) have gone into "postpone" mode. In several other cases we are also looking at setting up virtual meetings and will conduct our business either by conference call or over internet channels.

The RSGB was due to hold its thrice-yearly face-to-face meeting of the Volunteer Leadership Team (VLT) yesterday, consisting of board members, HQ staff, committee chairman, honorary officers and regional representatives. Instead, because of Covid-19 concerns, we ran it as a video conference using the Cisco Webex system. It worked very well, despite hardly any of the 34 participants having even heard of it before. 73, Richard G4DYA From dbthompson at me.com Sun Mar 15 10:50:25 2020 From: dbthompson at me.com (David Thompson) Date: Sun, 15 Mar 2020 07:50:25 -0700 Subject: [Elecraft] OT: Well-being check In-Reply-To: <023201d5fac2$baa1e830$2fe5b890$@LNAINC.com> References: <023201d5fac2$baa1e830$2fe5b890$@LNAINC.com> Message-ID: > On Mar 15, 2020, at 05:10, Lyn Norstad wrote: > > How is everyone doing? Good morning from almost the west coast. My middle child (Older Son) is visiting with me here in Carson City for awhile. We had a couple of nice days last week and spent them over at a local park. I setup a SOTAbeams mast and wire antenna and played with the KX3 driving a Virgil Stamps MiniPacker HF amp, which will produce 30-40w, depending on band and drive. I was able to check into the Noontime Net and a couple of others with a wire and 30w phone. Then the winds and rain, now snow returned. So we are flying some toy drones I bought (in the house) and learning to fly them line-of-sight. He?s studying for the Tech exam and I think he?ll pass it.

I?ve always been an early riser, but not that early. However, this year the time change really threw me for a loop. I?m dealing with a very ill canine friend and that?s not helping. She is scheduled for brain surgery to remove a tumor the first of the month. I?m hoping she makes it that long. It would be good to have a few more years with her.

This is especially important if you have the CONFIG:AFSK TX setting set to FIL ON (which is recommended). By any chance were you using a Mark tone in the software that was different from the PITCH setting in the radio? 73, Rich VE3KI N9OK wrote: Hi, I've recently upgraded my K3 with numerous upgrades including a KIO3 Bboard.

My guess a quarter-wave vertical with some radials will work. How well? You will only find out by trying it. My favorite HF antenna has been the simple half-wave dipole -cheap, easy, quick. I did eventually obtain a triband trap yagi for 20-15-10m and works much better. Currently I have a 80/40m inverted-V ...and it works well for my needs. Worked a station on 80m SSB with S9 signals on Saturday at 11am! Sure he was only a hundred+ miles (short range is often harder). K3/10+KXPA100 On 630m (475-KHz) I have a 43-foot high inverted-L (that is 8% of a quarter-wave). And my radials are limited to 100-foot by my property lines. Obviously a very poor antenna. My CW signals was heard 4,000 miles away in Buffalo, NY. Not an everyday occurrence, but a surprise to me. 73, Ed ----------------------- There is some erroneous information here, as well as in Don W3FPR's post. Radials, whether buried or raised, only affect near field ground return currents.? You cannot improve ground conductivity beyond the radials, and the strength of the low angle lobe is directly affected by the ground conductivity several wavelengths distant from the vertical.? This is well established science and you can clearly see the effect in simple models. Dave??

I went thru KE7X's handy tutorial about how to make things work, and I had temporary success. Here's the process, paraphrased: * Ensure that MENU:MIC SEL is set to LINE IN and MENU:MIC+LIN is OFF * Optionally, set CONFIG:AFSK TX to FIL On. This adds a 400 Hz transmit audio filter to the AFSK signal to improve transmit signal-to-noise. * Hold TEST to put the K3S into transmit test mode. The TX icon will start to flash. * You may have to adjust the Main menu's VOX GN to get the audio from the computer to reliably key the transmitter. * If you are in transmit test mode, hold TEST to return to normal transmit. Note that all these settings were already set up correctly, but I carefully went thru the process and toggled each item off the correct setting, then back on. So, things were working perfectly, where I could transmit diddles directly from MMTTY. However, after I rebooted, things did not work after that. Proper operation was achieved again by modifying this menu pick: DATA MD: AFSK A:45 bps <-- modify to 75pbs. Now I can transmit again. Put it back to 45 where it belongs.

I have 67 years of operating experience. 2. I have used full sized yagis, some times stacked on 40 up through 10. Some were owned at my own station and others were available as a guest. I am a CW OPERATOR. A couple of friends were deep into antennas. They did not want to operate contests. So I was asked to operate on CW to see how their stations measured up. 3. I have not used a gain antenna on HF in almost 30 years. I have 370 DXCC Mixed total. I never have missed a DXCC entity that I needed in those 30 years. 4. When I moved to my current QTH 30 years ago I threw up a wire (1/4 wave) with 2 radials for 30 meters. That was my 1st antenna at the new QTH. I woke at 4 AM and found a pile up on 30 meters on a H44 DX pedition. They kept calling CQ plenty of answers but they did not reply to anyone. Well after about 5 minutes I called once. Amazed when they answered me. 5. Location is the most valuable criterion at a station. If you are fortunate to have a good location you really can compete. I am on the shore of the Ohio River East of the city of Cincinnati. I am about a half mile from that river. The River has cut a swath for hundreds of miles. Over 220 degrees I am 400 feet above that river. The River is 400 feet above Sea Level. My tower is 45 feet above ground. It is all down hill over that 220 degrees from my QTH. 6. On 160 I had an Inverted L with 30 radials 30 feet long each. Ran 500 watts and worked DXCC in 4 months. Beat out a friend who has a 4 square and thousands of feet of radials on 160. He ran three times my power. One morning I worked 3 JA s while he waited. He lives 90 miles from me. 7. I use a triband rotary dipole at 45 feet For 30 years. The important thing is I can rotate it. On LP on VK I ususally get 1 S unit better than the others. Still 500 watts. My Point ? MY 67 years of experience: L O C A T I O N is the best thing you can have. Not being close to Salt Water being on a hill is the best alternative. It has worked for me. I have had locals call me on the telephone. Can you hear JT1CO on 80 ? Let me see. Yup 2 calls and I am in his log. Antenna ? A 35 foot top loaded vertical. My buddy 25 miles away could not even hear the JT. He tried calling listening over my telephone. That did not work. Other similar occurrences too. Get a good location. Some are way better. Flat land sucks. 73 Jim W9VNE Sent from my iPhone From AE4PB at carolinaheli.com Sun Mar 15 18:01:35 2020 From: AE4PB at carolinaheli.com (AE4PB at carolinaheli.com) Date: Sun, 15 Mar 2020 18:01:35 -0400 Subject: [Elecraft] Off-Topic - Antenna element repairs Message-ID: <001101d5fb15$4bc16c30$e3444490$@carolinaheli.com> I have a vertical antenna to repair and install that I believe is the same as or close to a hi-gain AV-18HT. https://www.hy-gain.com/Product.php?productid=AV-18HT. The main antenna vertical was cut so it could be taken down. I purchased it used in hopes I could repair and install it. I have two different places that require repair. Purchasing new parts for the element appear to approach the cost of an entirely new antenna. I'm thinking of three different methods of repair but lack experience. 1. I can braze the elements using aluminum brazing rods and flux. 2. I can get them welded back together but am concerned that the tubing is very thin. 3.

After going to RX after TX, the RX gain drops by 40 dB or so. It is worse on 160m than on 10m. When the RX goes dead, a dit on the paddle (in cw mode) or press of the XMIT button restores the full gain. In the past this was not a common occurrence. This has become less than intermittent. Last night on 160m I was unable to work VP2VB on 160m FT8 as the drop in RX gain would cause the decode to fail. The RX gain would be fine for 10s after TX, but would then drop out. On FT8 there is no way to press the XMIT button without killing the decode. This problem seems to be somewhat related as to how long the TX function has been used. Obviously, calling VP2VB on FT8 keeps the radio warmer - it is driving a KPA500 amplifier. When in the 'low gain' mode switching between ANT1 and ANT2 does not fix the problem. The ATT and PRE functions seem to work as expected. Quite often the K3 will turn on in the 'low gain' state. TX seems to be fine. I don't notice any SWR jumps coming out of the 'low gain' RX state. My guess is that the RXB voltage is not stable or one of the RX pin diodes is bad. Anyone else had this problem or anything to check before sending the K3 back to Elecraft?

The overlaid section will be stronger than the original (two layers) if you do this correctly and have a long enough patch (which will depend on the overall length since length gives leverage). Some will suggest also adding conductive grease on the elements overlapping.? Other may also suggest adding two (at each end) small bolts at 90 degrees to each other to back up or replace the clamps (belts and suspender mode).? I don't suggest bolts as they're hard to realign next time and reduce the amount of material needed at the patch (makes it weaker). I've also (because it was available) taken fiberglass rod and put that INSIDE the two aluminum ends, with bolts to keep it in place and a clamp to span any distance between the ends.? It worked but isn't as electrically sound. I would not use a pop rivet, it's not bonded hard enough to the elements (you'd still need an overlaid section), isn't strong enough over time and could create a weak enough contact point for RFI later.? Brazing also brings in a dissimilar metal and creates even more issues.

I spent the day today working on an HF Terrain Analysis - specifically for VK, ZL, and JA DX. Looking at that, I think I'm starting to get a picture of the issue. For VK DX - it looks like there is a terrain obstacle. And that is coupled with very poor ground reaching out many wavelengths. It makes sense that low TOA is called for. And in this case the lower the TOA, the more detrimental the ground effect is going to be. And this appears to be confirmed - as verticals have always been poor performers here over the years. All of which seems to indicate that increased height with horizontal polarization is probably going to be the most practical approach.

For the first 5 years I had 2000' of radials with my antenna tuner in the shack. For the last 4 years I have had 3000' of radials and a tuner at the base of the antenna. I have not worked everything I have called, but have managed to confirm 303 countries including 84 on 160 and 1745 on DXCC Challenge. Friends tell me I am very fortunate... I agree. I knew I could get on the air, but I am having greater success than I expected and therefore tons of fun. I have seen some folks delay putting up an antenna for years because they could not decide what would be the very best antenna. I say learn what you can... put up something... and improve on it over time if you are able.

(This is SWR at the input to the ATU, if used.) The current ATU firmware does a pretty good job of keeping the SWR below about 1.3:1, which usually is low enough. In any case, I just ran a simple test on 160, where I have an antenna I can easily tune to 1:1, or deliberately higher. The ATU was engaged, but it's settings were not changed during the test. The SWR indicated was that at the ATU input (amplifier output).? I found that the output power remained nearly constant up to 1.4:1, but the current increased from 58 to 62 A. (This with no adjustment of the K3 power, though the indicated input power varied slightly.) At 1.5:1, the current exceeded 65 A and the amplifier faulted. By reducing drive, I was able to run it at 1.4 kW output and 60 A. The above is typical of my experience on other bands, etc. The effect of SWR on the amplifier, of course, depends on the actual impedance at the amplifier, so in some cases it may be more or less sensitive to SWR. Do others see similar effects? 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From jim at audiosystemsgroup.com Mon Mar 16 23:21:51 2020 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 16 Mar 2020 20:21:51 -0700 Subject: [Elecraft] Off-Topic: Your advice/suggestion about antenna In-Reply-To: <20200316143711.1fa1e31b6b6b329ecc65be958babcc1f.fc338a3ab2.wbe@email09.godaddy.com> References: <20200316143711.1fa1e31b6b6b329ecc65be958babcc1f.fc338a3ab2.wbe@email09.godaddy.com> Message-ID: <8daa4b48-3b1c-acba-e15b-ad05ed6be020@audiosystemsgroup.com> Blank email. 73, Jim K9YC On 3/16/2020 2:37 PM, Dave New, N8SBE wrote: > > ______________________________________________________________ > 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 jim at audiosystemsgroup.com > From a.durbin at msn.com Tue Mar 17 06:24:37 2020 From: a.durbin at msn.com (Andy Durbin) Date: Tue, 17 Mar 2020 10:24:37 +0000 Subject: [Elecraft] KPA1500 SWR Tolerance Message-ID: "The effect of SWR on the amplifier, of course, depends on the actual impedance at the amplifier, so in some cases it may be more or less sensitive to SWR."

It's been up for about 10 years, so needs some TLC, but I'd say that it's held up pretty well, considering everyone says that quads don't (hold up well). A 2-el quad performs at or better than a 3-el yagi at low heights above ground (35 vs 65 ft), and I have the wallpaper to prove it. The ZS6BKW is up about 35-40 ft. (slopes at one end) and doesn't do so well for DX, but is a killer for NA contests (NAQP, Sweepstakes, MI QSO party) from the Midwest. This all fits on a postage-stamp lot, in a non-HOA neighborhood.

There are no magic numbers regarding lengths. There are two questions to answer: (Q) How long should the antenna be? (A)? As long as one has for available space. (Q) How long should the feed line be? (A) Long enough to reach from the feed point to the station operating position. Now, the length of the wire is relative, being the most one can put up in the clear.? The feedline, be it true open wire of about any impedance or ~450 window line or 300 ohm transmitting twin lead is all that is necessary. Agreed, some combinations of lengths are more difficult to match.? If this occurs, then add some 4 to 6 ft of feed line length, or add 4 to 10 ft to antenna length.?? Or shorten the feed line length. ? The point being, if one can attain a 2:1 match or better it will radiate quite efficiently.? If your amp won't tolerate this, then a bit more attention to length is required. The topic of what balun to use is an extensive discussion. ? Most baluns are OK, while some are just purely awful.? Some may not alone provide the necessary common mode current rejection.? Power rating of baluns are for a MATCHED condition, to which we most always use them in a highly unmatched condition.? Thus the suggestion is one consider a much higher power rated balun than one intends to run. ? My reference to balun usage and design is https://www.dj0ip.de/balun-stuff/. The issue of using a balanced feed system is much easier than the "old ham lore" will stipulate.? Just use common sense.? It ain't rocket science folks,? nor does it require a Ph.D to make it work and work quite well, I might add. Yes, it is very much OK to bring the balanced feed line all the way to the operating position where it then attaches to the balun of ones choice.? It is not necessary to have the balun outside and bring the feed point in via a length of coax.? If one is going to use open wire line or balanced line, then don't screw up the system by introducing a length of coax to go from the station to the balun in the outside world.??? There will be an unbelievable amount of high SWR on that coax {and equal amount of loss} and likely a high amount of common mode current.? Do it correct the first time, enjoy the very favorable results, and forget about the "old ham lore" for it is not correct!? I've only been doing it this way for some 50+ years. I sit here today with a very modest station.? Then antenna is a 256 ft center fed wire with 450 ohm window line. The center of the antenna is 50 or so feet and the feed line is what ever it took from a 100 ft roll to get from the feed point, through the attic eve, drop down through the ceiling to the operating position. There was about 25 ft of 450 ohm window line left over.? I easily work? all modes and frequencies 160M - 6M? up to 500 watts from my KPA500 and KAT500.?? The antenna and feed line have been in the air and in place for 10+ years and I expect it to last longer than I do. Yes, when it rains or snows the SWR goes up, but so what? ? That is what the dang tuner is for and it does an excellent job with just the touch of a button. If you only have 90 ft for the antenna, that's OK,? If you only have 55 ft for the antenna, that's OK.? The feed line goes from point A to point B, whatever that length might be.? Shorter lengths of antenna become a real challenge to get a good match on frequencies lower than the resonant length but it will work if you can match it.?? For get about the charts, the computer modeling, and put up what you can, in a reasonable fashion, and begin to enjoy ham radio. 73 Bob, K4TAX On 3/17/2020 2:42 PM, Dave New, N8SBE wrote: > 2) A ZS6BKW dipole, which is 92 ft. long, includes a 40 ft. window line > section, and then 75 ft. of coax.

As you might expect, we have been extremely busy adjusting our operations to the announcement from Santa Cruz County to 'Shelter in Place'. Fortunately, we have been anticipating this possibility coming to our area, both from ongoing news coverage of the coronavirus spread and more recently when the counties in the S.F Bay Area to our north announced their own Shelter in Place order. It has been a very busy number of days here at Elecraft H.Q. Yes we are still alive and in operation, albeit with the majority of our employees working from home. We are just about to release a more detailed update on our web page and via direct email on this. I've copied it below for everyone here to read. Feel free to ask me questions here or via direct email. I may not respond immediately, but I'll try to answer as much as I can. 73, Eric *elecraft.com * ---- Elecraft's priority is the safety and well-being of our employees, customers and the community in which we live and work. We wanted to reach out and make sure that all of you are staying safe as well as share a few of the steps we have taken to ensure we are able to protect our colleagues here at Elecraft while maintaining a high level of support for all of you. *Santa Cruz County Shelter in Place * Santa Cruz County has issued a three-week "shelter in place" order from 3/17 through 4/ 7 to guard against the further spread of the Coronavirus. Residents have been ordered to ?shelter in place? and refrain from all non-essential activities outside of their home. Telecommuting from home is encouraged. Employees can travel to work to retrieve equipment and documents needed to telecommute, and companies are allowed reduced staff on-site to support telecommuting along with protection of inventory, security and some other business functions. *What is happening at Elecraft* Sales and Customer Support are setting up to take calls to Elecraft from their home offices during our normal work hours. We will be trying our best to maintain a business-as-usual service, but, inevitably, you may hear kids laughing or dogs barking in the background during a call with us. We appreciate your patience and understanding as we navigate the current reality together with all of you. We will continue to ship products that we have in stock. Items that we do not have in stock will be shipped later in April when we are able to resume full manufacturing. All of our engineers are able to continue their work on projects off-site, including K4 development. Manufacturing and production at Elecraft will continue when Santa Cruz County's "shelter in place" is lifted. *Placing Orders* You may place orders online at elecraft.com or by calling Sales at 831-763-4211. We will continue to ship products that we have in stock. Items that we do not have in stock will be shipped later in April when we are able to resume full manufacturing. We will not process your payment until we are able to ship your order. If your order is not shipped within a week, we may have to contact you for payment information since our system does not store credit card numbers. You may also place a note on your order form to process your payment immediately, and you?ll receive a shipping tracking number as soon as we?re able to ship your order. If you have any questions regarding your order or about any of our products, please feel free to call us at 831-763-4211 or email sales at elecraft.com or support at elecraft.com All of us at Elecraft hope you stay safe and healthy, and we thank you for being a part of our Elecraft Family.

One simple post, Bob, and you've covered pretty much everything anyone needs to know about wire dipole-type antennas. This is exactly the process I worked thru in deciding to build mine last year, with one embellishment - and that was to fine tune the size (I had 400 feet to work with) based on the particular frequency on which I wanted it to actually be a 1.25 wavelength EDZ, for maximum performance on 3.5 MHz (360 feet). Like you, I am feeding it from the KPA/KAT500 but needed to use a short run of coax into the attic in order to connect to the balun, which is right above the shack ceiling. At the balanced line feedpoint (I am using approximately 160 feet of 600 ohm open wire ?TrueLadderLine?) I measured the impedance with an analyzer across all bands 160 ? 6m and calculated that I needed a 4:1 impedance transformer in order to present a workable match to the KAT. But I also wanted a 1:1 Current Mode balun to reduce common mode issues. Coincidentally at just that time, Balun Designs was developing a hybrid balun that actually incorporated both into one package. I couldn?t be happier with how this all came together. It is broad banded, visually acceptable and most important a great performer. 73 Lyn, W0LEN "Bob McGraw K4TAX" posted: As discussed below, what ever you wish to call it, the antenna that is, being: a G5RV, a double Zepp, an all band antenna, a center fed dipole and a few more brand names, the center fed dipole with with a balanced feed and a suitable balun can be matched on all bands, 160M - 6M with the tuner in the K3S or the KAT500. There are no magic numbers regarding lengths. There are two questions to answer: (Q) How long should the antenna be? (A) As long as one has for available space. (Q) How long should the feed line be? (A) Long enough to reach from the feed point to the station operating position. Now, the length of the wire is relative, being the most one can put up in the clear. The feedline, be it true open wire of about any impedance or ~450 window line or 300 ohm transmitting twin lead is all that is necessary. Agreed, some combinations of lengths are more difficult to match. If this occurs, then add some 4 to 6 ft of feed line length, or add 4 to 10 ft to antenna length. Or shorten the feed line length. The point being, if one can attain a 2:1 match or better it will radiate quite efficiently. If your amp won't tolerate this, then a bit more attention to length is required. The topic of what balun to use is an extensive discussion. Most baluns are OK, while some are just purely awful. Some may not alone provide the necessary common mode current rejection. Power rating of baluns are for a MATCHED condition, to which we most always use them in a highly unmatched condition. Thus the suggestion is one consider a much higher power rated balun than one intends to run. My reference to balun usage and design is https://www.dj0ip.de/balun-stuff/. The issue of using a balanced feed system is much easier than the "old ham lore" will stipulate. Just use common sense. It ain't rocket science folks, nor does it require a Ph.D to make it work and work quite well, I might add. Yes, it is very much OK to bring the balanced feed line all the way to the operating position where it then attaches to the balun of ones choice. It is not necessary to have the balun outside and bring the feed point in via a length of coax. If one is going to use open wire line or balanced line, then don't screw up the system by introducing a length of coax to go from the station to the balun in the outside world. There will be an unbelievable amount of high SWR on that coax {and equal amount of loss} and likely a high amount of common mode current. Do it correct the first time, enjoy the very favorable results, and forget about the "old ham lore" for it is not correct! I've only been doing it this way for some 50+ years. I sit here today with a very modest station. Then antenna is a 256 ft center fed wire with 450 ohm window line. The center of the antenna is 50 or so feet and the feed line is what ever it took from a 100 ft roll to get from the feed point, through the attic eve, drop down through the ceiling to the operating position. There was about 25 ft of 450 ohm window line left over. I easily work all modes and frequencies 160M - 6M up to 500 watts from my KPA500 and KAT500. The antenna and feed line have been in the air and in place for 10+ years and I expect it to last longer than I do. Yes, when it rains or snows the SWR goes up, but so what? That is what the dang tuner is for and it does an excellent job with just the touch of a button. If you only have 90 ft for the antenna, that's OK, If you only have 55 ft for the antenna, that's OK. The feed line goes from point A to point B, whatever that length might be. Shorter lengths of antenna become a real challenge to get a good match on frequencies lower than the resonant length but it will work if you can match it. For get about the charts, the computer modeling, and put up what you can, in a reasonable fashion, and begin to enjoy ham radio. 73 Bob, K4TAX From Lyn at LNAINC.com Tue Mar 17 18:30:13 2020 From: Lyn at LNAINC.com (Lyn Norstad) Date: Tue, 17 Mar 2020 17:30:13 -0500 Subject: [Elecraft] Off-Topic: Your advice/suggestion about antenna In-Reply-To: <10be8667-9cf6-27f9-91ba-0e71928560bb@blomand.net> References: <20200317124215.1fa1e31b6b6b329ecc65be958babcc1f.040cf1273d.wbe@email09.godaddy.com> <10be8667-9cf6-27f9-91ba-0e71928560bb@blomand.net> Message-ID: <085201d5fcab$a0482ef0$e0d88cd0$@LNAINC.com> Bingo!

NOT! While non-resonant dipoles are certainly viable transmitting antennas, there is FAR more to know about them, including: 1) Their directional patterns are different on every band; 2) They have very poor rejection of common mode noise on the feedline unless choked at the FEEDPOINT (i.e. where the feedline connects to the horizontal wires) and I know of no practical choke to do that effectively. 3) #2 is true because in the common mode circuit, the feedline is part of the antenna unless the choke disconnects it, and it can only do that at the feedpoint. The only thing that a choke can do farther down the line is add high impedance to that common mode circuit, creating a current minima at that point. Remember, it's an ANTENNA, not a simple series circuit. 4) A well-balanced transformer coupled tuner CAN present an open to the common mode circuit, but the rest of the feedline is still part of the antenna, so any common mode noise received on the feedline is coupled to the antenna, and from there back down the feedline as a differential signal. 5) Many years ago, N7WS published his research showing that window line gets pretty lossy when wet. It's in one of ARRL's excellent Antenna Compendiums. Bottom line -- this is one of those antennas that "works," but how well it "works" depends on your local noise level and whether the station(s) you want to work are in one of the nulls of its pattern. It's one of those antennas that was a lot better idea 20 years ago when it was highly advocated by smart engineers when noise levels were a LOT lower for most hams than they are today. 73, Jim K9YC From xdavid at cis-broadband.com Tue Mar 17 20:54:48 2020 From: xdavid at cis-broadband.com (David Gilbert) Date: Tue, 17 Mar 2020 17:54:48 -0700 Subject: [Elecraft] Off-Topic: Your advice/suggestion about antenna In-Reply-To: <3754529e-bd6c-2506-2ce7-5187eb89cfa0@audiosystemsgroup.com> References: <20200317124215.1fa1e31b6b6b329ecc65be958babcc1f.040cf1273d.wbe@email09.godaddy.com> <10be8667-9cf6-27f9-91ba-0e71928560bb@blomand.net> <085201d5fcab$a0482ef0$e0d88cd0$@LNAINC.com> <3754529e-bd6c-2506-2ce7-5187eb89cfa0@audiosystemsgroup.com> Message-ID: <40b463a4-c533-a178-64d9-75f9cb5c4363@cis-broadband.com> Thank you, Jim.?

For example - 1) Their directional patterns are different on every band; Exactly, and this plays perfectly into my coverage needs. For example, I need (and designed for) 80 meter coverage concentrated in a N-S direction. For every other band, I need (and designed for) more of an omni pattern. That works best for me and is reasonably well provided by this antenna's multi-lobe patterns. 2) They have very poor rejection of common mode noise on the feedline unless choked at the FEEDPOINT (i.e. where the feedline connects to the horizontal wires) and I know of no practical choke to do that effectively. I have a hybrid 4:1 / 1:1 balun at the shack end of the balanced feedline and have absolutely no issues. None. It is a Balun Designs 4116t. 5) Many years ago, N7WS published his research showing that window line gets pretty lossy when wet. It's in one of ARRL's excellent Antenna Compendiums. Agreed, and that's why I didn't use window line. I used open-wire, or true ladder line, from TrueLadderLine.com. Rain has no effect unless the line itself is pressed against tree leaves (I do have to do a little tree trimming now and then). Noise level is markedly lower than reported by other hams in the area, whether using vertical or compromised horizontal antennas. My noise level went down at least 2-3 S units in switching from the attic-mounted G5RV Jr, while both received and transmitted signals are higher by a similar amount. Bottom line is that it does what it is intended to do, and does it quite well. 73 Lyn, W0LEN From rmcgraw at blomand.net Wed Mar 18 10:18:31 2020 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Wed, 18 Mar 2020 09:18:31 -0500 Subject: [Elecraft] Off-Topic: Your advice/suggestion about antenna In-Reply-To: <001001d5fd22$398bb430$aca31c90$@LNAINC.com> References: <20200317124215.1fa1e31b6b6b329ecc65be958babcc1f.040cf1273d.wbe@email09.godaddy.com> <10be8667-9cf6-27f9-91ba-0e71928560bb@blomand.net> <085201d5fcab$a0482ef0$e0d88cd0$@LNAINC.com> <3754529e-bd6c-2506-2ce7-5187eb89cfa0@audiosystemsgroup.com> <001001d5fd22$398bb430$aca31c90$@LNAINC.com> Message-ID: <9008d9d2-30bf-d1fb-ac7e-81b5236381c0@blomand.net> I have to agree with Lyn on several points.?? I do agree the directional pattern is different on every band.? For me, that suffices as I am not one to aggressively chase DX.?? If you need specific directional patterns, then other considerations for antennas should be undertaken. On point #2, the balanced feed line is twisted at my installation. This is one advantage to the vinyl covered line. This makes essentially a twisted pair which Bell Labs many years show is a way to minimize induction into the feed line.??? In transforming from balanced to unbalanced, I use two "baluns" at the shack end of the feed line.? One is a 4:1 dual core balun operating as a wide band transformer and the second is a 1:1 balun operating as a balanced to unbalanced configuration.? It also provides a significant amount of common mode current rejection. This has been verified by measurement of the common mode current on the shield of the short jumper between the balun and the ATU. {See https://www.dj0ip.de/balun-stuff/ } As to the research N7WS,?? I've read his paper several times.? In fact, a fresh copy is on my desk.?? Due to test equipment limitations, he did his wet/dry line measurements at 50 MHz and higher with a short piece of feed line.??? I did my measurements between 1.8 MHz and 30 MHz with 100 ft of feed line.? The line was measured, for wet/dry purposes, in a matched impedance configuration between 1.8 MHz and 30 MHz.??? I agree with his data on velocity factor changes but can not agree on increased loss data. The work of KV5R where he references; "Many amateurs use non-resonant (even random length) antennas fed with open wire lines and tuners.? They radiate signals just as well as those fed with coaxial cable and resonant antennas. ......? ARRL Antenna Book, Ch2"? As long as the antenna length is 1/2 wavelength at the lowest frequency the efficiency is near 90%.???? {See KV5R.Com} The work of G3TXQ seems to contradict parts of the work done by N7WS.??? His measurement for wet/dry line being 60ft of 300 ohm line configuration with a 6:1 SWR does more agree with my measurements using 100 ft of line.? Thus 60 ft of dry line at 27.0 MHz shows 0.71 dB loss and 0.93 dB loss when wet.??? His measurements of 450 ohm window line fall within the same range of loss measurements between wet or dry. As to noise in the local area at my QTH, having two different antennas, one being a resonant dipole fed with a 1:1 current balun at the feed point and RG-213 and the other being a 256 ft center fed wire with a balanced feed I do not find the balanced fed antenna to be any more prone to noise than the resonant dipole on 80M and 20M.??? There is a bit of a skew in orientation due to placement of the ends. A 2nd test, at a 2nd site which easily allows one antenna to be pulled in place and measured and then lowered and the a 2nd antenna pulled into the same location, I find again there is no difference between a coax fed antenna and one fed with balanced feed line, in terms of noise pickup.??

Hi Len, The problem is noise pickup on the line. I think I remember that your QTH is relatively isolated, hence not much local noise. The other question is, how would you know if you had an issue without an A/B comparison to a resonant dipole with a choke at the feedpoint? None.? It is a Balun Designs 4116t. This company appears to have no clue about how chokes work to kill noise, but they're very good at selling them. Their definition of "working" seems to be that the customer pays and the "balun" doesn't burn up. Last year, a member of our contest club building a station in the Caribbean asked me to measure one of their products. It looked NOTHING like the data sheet on their website. After I circulated the data to a few engineers as a "heads up," the plot disappeared from their website. 73, Jim K9YC From jim at audiosystemsgroup.com Wed Mar 18 15:24:03 2020 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 18 Mar 2020 12:24:03 -0700 Subject: [Elecraft] Off-Topic: Your advice/suggestion about antenna In-Reply-To: <9008d9d2-30bf-d1fb-ac7e-81b5236381c0@blomand.net> References: <20200317124215.1fa1e31b6b6b329ecc65be958babcc1f.040cf1273d.wbe@email09.godaddy.com> <10be8667-9cf6-27f9-91ba-0e71928560bb@blomand.net> <085201d5fcab$a0482ef0$e0d88cd0$@LNAINC.com> <3754529e-bd6c-2506-2ce7-5187eb89cfa0@audiosystemsgroup.com> <001001d5fd22$398bb430$aca31c90$@LNAINC.com> <9008d9d2-30bf-d1fb-ac7e-81b5236381c0@blomand.net> Message-ID: <421a0f94-bb2c-e30a-2e54-30d056e2a1f1@audiosystemsgroup.com> Hi Bob, On 3/18/2020 7:18 AM, Bob McGraw K4TAX wrote: > On point #2, the balanced feed line is twisted at my installation.

First, twisting applies ONLY to coupling INTO the line -- that is, the DIFFERENTIAL circuit. Second, to be effective for that, distance between twists must be a very small fraction of the wavelength. For example, the high twist rate (called the "lay" by cable engineers) of CAT5 prevents very good rejection of differential mode crosstalk into the low HF spectrum. Measuring common mode current at the shack end of a line tells us NOTHING about common mode current anywhere else on the line, because, like any antenna, current varies along the wires that form it. In the common mode circuit, the feedline is a single wire connected to the center of the antenna on one end. With no choke and no transformer in the shack, the connection is to "ground," whatever that is. That causes the current to be near a maxima, depending on what "ground" is, and current on the wire varies along the wire (the line) like with any other antenna. A quarter wave up from the maxima it will be a current minima and a voltage maxima; a half wave up is another current maxima. This is not a transmission line effect, it is an antenna effect; VF ~ 0.98, the VF of a wire with insulation. An effective choke and/or a transformer at the shack end forces a current MINIMA at that point, with maxima and minima along the line up to the intentional antenna. A "balun" that is inductive or capacitive at the frequency of interest will modify that current distribution; so will a transformer that has capacitance between windings.

Wes's choice of VHF is quite reasonable, and on a percentage basis, IS representative of loss at MF and HF. Because loss for lines using non-ferrous conductors increases approximately as the square root of frequency, it's easier to measure at VHF, but the curves for all such cables will be approximately parallel to each other. This can be seen in the plot on page 2 of this link. All of the lines are approximately parallel except for the kW twinlead (CCS conductors) and the coax with a CCS center. http://k9yc.com/Coax-Stubs.pdf As to your tests between antennas at your QTH -- what matters is signal to noise on RX, and the differences are likely to be in the 3-9 dB range, depending on what noise sources are around you. To observe them, we must do A/B comparisons on many WEAK signals, switching between the antennas many times on each signal. Where this matters is copying weak signals -- we won't hear differences on stronger ones. And it only matters if your QTH is noisy. 73, Jim K9YC From jim at audiosystemsgroup.com Wed Mar 18 15:49:39 2020 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 18 Mar 2020 12:49:39 -0700 Subject: [Elecraft] Off-Topic: Your advice/suggestion about antenna In-Reply-To: <00a301d5fd5b$891c9260$9b55b720$@LNAINC.com> References: <20200317124215.1fa1e31b6b6b329ecc65be958babcc1f.040cf1273d.wbe@email09.godaddy.com> <10be8667-9cf6-27f9-91ba-0e71928560bb@blomand.net> <085201d5fcab$a0482ef0$e0d88cd0$@LNAINC.com> <3754529e-bd6c-2506-2ce7-5187eb89cfa0@audiosystemsgroup.com> <001001d5fd22$398bb430$aca31c90$@LNAINC.com> <278c6321-60f4-798e-d660-2686c580b40d@audiosystemsgroup.com> <00a301d5fd5b$891c9260$9b55b720$@LNAINC.com> Message-ID: <2d8cbf25-14d9-3ddb-bdd2-3c33ede463ba@audiosystemsgroup.com> My work has been published for ten years, the most current work for two years, and there have been millions of downloads. 73, Jim On 3/18/2020 12:29 PM, Lyn Norstad wrote: > so I am sure they would welcome your expertise. > > Perhaps you should make your services available to them. > From lladerman at earthlink.net Wed Mar 18 17:30:03 2020 From: lladerman at earthlink.net (W0FK) Date: Wed, 18 Mar 2020 14:30:03 -0700 (MST) Subject: [Elecraft] Shipping Status updates In-Reply-To: References: <985223B4-CA48-4F1A-B7E2-6B8736D2D4B4@poxika.net> Message-ID: <1584567003925-0.post@n2.nabble.com> Sent my KX2 back last week for repair, and got a notice from FedEx of a delivery exception: "Local delivery restriction, delivery not attempted."

And there is a simple explanation of one of the flaws of the KAT500 design! Consider the case in which a particular bin is in a "band" that has 2 enabled antenna.? Let's say these are ANT2 and ANT3.? ANT2 is an antenna that is in development and is frequently tuned. ANT3 is a dummy load.? We start by setting one of the 6 tuning solutions to bypass to match the dummy load.? Then we launch on a series of experiments with ANT2, each having a new tuning solution.?? I cannot reserve one of the 6 ATU settings for ANT3 and I cannot reserve a small block of ATU setting for my ANT2 experiments.? After 6 tuning attempts on my experimental ANT2 my bypass setting for ANT3 is wiped out.? ?When I select ANT3 I will probably fault my KPA500. There are multiple scenarios in which in would be advantageous for the operator to be able to control how the 6 available solutions are allocated. Allocation could be controlled by allowing the user to assign each of the 6 tuning solutions to a specific ANT port. Allocation could also be controlled by allowing the user to "lock" one or more tuning solutions. "So please do not ask Dick anymore about this subject."

It appears that the number of on-line orders for various products (like toilet paper) has gone way up as people are not able to obtain them locally. We are seeing deliveries delayed by a day or two for both UPS and FedEx. It doesn?t surprise me that the folks in Watsonville are seeing the same thing since we are all serviced from the same Bay area facilities. The good news here is that traffic has pretty much disappeared as employees at companies in the Bay area are working from home. It is quite unusual to see the interstates empty. Have patience, this will come to an end, hopefully sooner than later. But also realize that the great folks at Elecraft are still working to get product shipped, repairs accomplished and returned and support questions answered. 73!

Regedit is NOT the place to wipe out a program.? If you (as you said) don't know much about Windows, it is however the perfect place to make an unrecoverable error and trash the entire computer.? It is one of the core elements of the OS.? If you don't understand, don't attempt here, it's a dangerous place to learn (by mistake). 2a) The Windows key (four small window panes) with B /_*may*_//__/ bring that errant program back into viewing ability. (Windows B at the same time) 2b) Use the Task Manager (right click on the taskbar at the bottom) to 'End Task' if you can't get the upper right X to kill it. Ending a taskwill lose whatever changes you've made in that application since starting it but that's often a cause of the issues too. If you wish to remove a program, uninstall it. If you wish to clean or purge the registry of residue (and other things), use 'CCleaner' (Crap Cleaner) which will do it with intelligence and safety.? It is free but has the (nasty) habit of wanting to stay running in the background, so get into the program settings and turn that 'feature' off.? You'll be amazed and how much 'stuff' gets purged if you use this app. When CCleaning a _registry_, run the cleaning cycle again until it says nothing found.? Removing one old piece in the registry often causes others to not be needed as well.? Three times is 'usually' enough passes. CCleaner MAY not get all the folders that installed software leaves behind, you have to hunt and dispose of them manually and CAREFULLY.? Again, this can be a dangerous place to play if you don't understand. (I've used CCleaner for years, I'm not a shill.) After you've done this, then you can reinstall the software if you wish. Now, back to the topic of the W2 software. Practice safe computing, hi. 73, Rick NK7I PS On 3/19/2020 11:56 AM, Bill Steffey NY9H wrote: > STAY WELL ALL.. > > got my W2s in circuit...??

What's broken? Message-ID: I've reached out to Elecraft Tech Support on this issue. With their locale on lockdown, I think they have their hands full just trying to maintain some sense of normalcy. So I'm hoping someone here can point me in the right direction. I've recently upgraded my K3 with numerous "last time buy" options (KAT3A antenna tuner, 2 KSUN3A synthesizers, and KIO3B usb board). One goal was to remove the Microkeyer II and simplifying the setup. What I'm finding now is that I can't make RTTY work correctly. I use MMTTY to generate a simple warble signal, which is sent to my K3. The K3 is set to AFSK-A, VOX enable, audio levels set correctly. What happens is that the K3 TX LED illuminates, but nothing is heard with the Monitor (ie, thru the K3 speaker), and there is no RF transmitted. However, when I use DATA-A, I do hear tones using Monitor, and there is RF power. I get the same results using either the K3 internal sound card, or externally-generated audio (fed from my PC soundcard to Line-In on the K3). Hoping there was a configuration issue, I factory reset my K3. That didn't help. It's probable this issue has been there since I first purchased my K3 new 8 years ago, but I never noticed. My MKII was used as my interface, and I was running FSK for RTTY. I did have many configuration issues with my MKII setup, which in retrospect might well be related to the AFSK issue that's now obvious. I'm suspecting this is a hardware issue. I have the 59 pages of schematics, and am going thru them to see if I can identify the issue so I can fix it. I would appreciate comments / suggestions / ideas to point me in the right direction. 73, Joe N9OK 73, Joe N9OK From wes_n7ws at triconet.org Fri Mar 20 09:04:04 2020 From: wes_n7ws at triconet.org (Wes) Date: Fri, 20 Mar 2020 06:04:04 -0700 Subject: [Elecraft] K3 doesn't work in AFSK-A mode but DATA-A does work.What's broken?

Message-ID: <09BE005B-9E63-4947-B2B7-68A1F6FD5CF7@cfl.rr.com> There is a lot of misinformation out there right now. The K60XV was discontinued due to the lack of a couple of rear adjust 8-60pf trimmer capacitors. I ordered the PC board, the Firmware pic processor, the 4 MHz crystal resonator and the extended dip plugs from Elecraft a couple of weeks ago. Customer service told me Elecraft is looking at mounting SMD capacitors on a little daughter board. I ordered my trimmers from Mouser and soldered them to slivers of protoboard. I am installing my board later today. Note that 3/4 of the circuits on the board are for Transverter support, which is mainly what I wanted. The trimmer caps are used to pull the 40 meter bandpass filter lower to 60 meters. My little daughter boards mount upside down with the trimmer caps centered over the holes in the board. Now if anyone wants more information, please ask. I went thru a lot to get this board. I was even willing to buy a radio with the board, remove the board and transfer to my radio, then resell the donar radio. I am glad that I never found a radio with the board to buy.

In-Reply-To: References: Message-ID: Joe, I created a super detailed and verbose YouTube video on the K3 RTTY / FSK setup . If you are not interested in setting up FSK, you still might find it handy on setting up the receive side of the equation. It goes in to great detail on selecting the tones you prefer and demos everything due to the fact that I made the video while an active contest was going on. You can jump head and back 10 seconds at a time on YouTube with the J and L keys and pause with the K or space bar... or jump ahead and back with the arrow keys 5 seconds. If you devour the whole video, it pretty much covers about all there is to cover on a K3 RTTY setup with N1MM and MMTTY / FSK. Again, the audio receive setup would still be helpful if you decide to go the AFSK route which is fine too. https://www.youtube.com/watch?v=EToCJ5GeZSE Based on comments over the last several years, many have found this useful and I only needed to go through the explanation once. :) Max NG7M On Fri, Mar 20, 2020 at 6:40 AM Joe N9OK wrote: > I've reached out to Elecraft Tech Support on this issue.

(I had to add confusion) but, I should mention that If do want to setup and transmit FSK internally to the K3/S AND you don't want to go the serial port route to control PTT and FSK off Serial port control lines. You could go with TinyFSK... which dedicates a single board computer to timing the Mark and Shift tones and PTT. So a couple years after the video you are watching now, I got around to making a TinyFSK Video which shows you how to use what is called a MORTTY Kit which makes using TinyFSK a breeze: https://www.youtube.com/watch?v=cT5SfhUtTAw All as I'm saying is, if you want to use internal FSK with your K3/S, you might want to consider buying a MORTTY kit if you don't want to use a serial port to control PTT and FSK mark/shift timing. So this video covers setting up MORTTY. Clearly, you can start off with AFSK and they venture into the FSK world later... or not... What you have in the K3/S with the later firmware is the best rig available for creating the cleanest / narrowest / bandwidth friendly FSK signal. And if you invest the time into setting up FSK, you are immune from ever under driving or over driving an AFSK signal. Not to open up this big freaking can of worms and start a rhetorical holy war that has been fought over the years between the pros and cons of FSK and AFSK... but using FSK on a K3/S alleviates you from worrying about setting AFSK drive levels. I'm not saying AFSK is bad... (I'm sitting here with fear and trepidation that someone is going to go on a tirade now about AFSK being better than FSK... GROAN... please don't do it here on the Elecraft List). I prefer FSK on my K3S because I never need to worry about fiddling with the drive levels in a moments notice when some DX station comes on RTTY (which is rare these days anyway with the FT modes, sigh...). One less thing to worry about. If someone else loves AFSK and dreams about AFSK and eats and sleeps AFSK and talks about how wonderful it is with your XYL... knock your self out. It's nice to have options. A properly driven sound card based AFSK signal is great too. I don't argue or deny that at all. Anyway, have fun tinkering and deciding what you like based on your own research. Max NG7M On Fri, Mar 20, 2020 at 3:19 PM n9ok wrote: > Thanks, Max.

I'm sold on the fact that the signal is probably cleaner. With my new KIO3B board I was hoping to get to a single-cable interface to greatly simplify my setup. At least, I thought I remembered reading that this was possible in Elecraft literature. I was really sick of the rats-nest of wires behind my K3. While I love the K3, sometimes I wonder if a Flex would be less hassle overall simply due to the simpler interface. I'm skeptical anyone has made RTTY with without some kind of addition interface beyond a simple USB cable since ASFK-A keying with VOX appears broken. Other digital modes shouldn't be a problem since DATA-A works. One of my friends, N7US, has been suggesting the MORTTY solution. Yet another interface. Sheesh. Why can't it just be all built into the K3? There's probably a good technical reason. I'm a EE who works on transmitters professionally but don't know the nuances of USB interface. I guess it must be hard to make it work. Or perhaps it's a limitation of how the K3/K3s is architected. It would be nice once the lockdown in CA is over, if one of the Elecraft people could chime in on this. BTW I'm about 1/2 thru your FSK video. Very informative. Thanks for putting it together. If I get an MORTTY I'll be sure to watch your other video.

I'm jealous. I'm not aware of any cockpit errors on this end. I was really hoping there was, and that's one reason I reached out on the reflector. I've made numerous cockpit errors which later were obvious to me once I was made aware of them. 73 Joe N9OK -- Sent from: http://elecraft.365791.n2.nabble.com/ From n9ok at arrl.net Sat Mar 21 07:26:00 2020 From: n9ok at arrl.net (n9ok) Date: Sat, 21 Mar 2020 04:26:00 -0700 (MST) Subject: [Elecraft] K3 doesn't work in AFSK-A mode but DATA-A does work.

My results were the same as Joe's. If I set data mode to DATA A things work as expected whether using VOX or my usual interface for PTT. However when I switch data mode to AFSK and VOX on and hit the TX button nothing happens, if I plug in the FSK interface just for PTT the K3 goes into transmit but there is no output and no tones in the monitor. My only conclusion is that there is some logic in the K3 or the new USB interface that is not routing the audio properly in AFSK mode. This is apparently not the case with the K3S. So Joe there is your answer. It is not your setup it is the radio. Maybe when the K4 is all rolled out they can take a look at the firmware and come up with a solution. My current FSK interface is 2 transistors and 2 resistors in each of 2 db9s connected in parallel to the db15hd pins for PTT & FSK. This allows for SO2V operation with minimal fuss. I have never owned a commercial interface, so have no experience with them.

To whit? the PowerCombo works with VFO A, but not VFO B. Most modern rigs come with dual VFO?s, of course. And many come with outright dual receivers. This ability to quickly monitor and move between bands/frequencies comes in handy in a variety of scenarios. And most of us happily bounce between these dual VFO?s without attaching any particular importance to one over the other. The problem lies with the KAT500, which reliably tracks VFO A? but which cannot track VFO B. The upshot being that if you?re operating VFO A, the KAT500/KPA500 PowerCombo will work as expected. But as soon as you toggle over to VFO B the KAT500 will manifest with clacking relays with every Tx on/off transition and the KPA500 will instantly fault with High Reflected Power if it is brought online in SWR conditions that required a tuned solution from the KAT500. Said differently, if you?re operating in conditions where native, un-tuned SWR is low ? where you don?t need the KAT500, in other words - the KPA500 works perfectly. But as soon as you move to a frequency with a moderate-or-higher SWR ? a situation where you need the KAT500 to insert its tuned solution ? it cannot do so, and the KPA500 faults. The behavior is independent of the best practices usually espoused for the KAT500? always operate in ?Manual,? ?train the tuner? to lock in inductor/capacitor settings in advance, and do that pre-tuning with 25-watts or more for greater accuracy. This VFO B problem applies to the Kenwood TS-590SG, TS-890S, TS-990S, and perhaps others. On their own, the KAT500/KPA500 PowerCombo are a remarkable addition to any shack. Profound is the word I?ve often used to describe their impact. However, the inability to use VFO B in conjunction with them is a pretty major failing. I have no information one way or the other, but I suspect the KPA1500 also suffers from this issue. Probably the thing that surprises me most is that this issue has apparently existed for years? and yet has not been socialized anywhere that I?m aware of. Neither the Kenwood TS-890S User Manual nor the Kenwood TS-890S In-Depth Manual make mention that their VFO?s A and B implement slightly different character streams. Elecraft?s KAT500 Automatic Antenna Tuner Owner?s Manual doesn?t mention that interfacing with Kenwood radios is a problem. Fred Cady, KE7X (RIP), doesn?t mention it in his KPA500 Amplifier and KAT500 Tuner manual. And it doesn?t appear to have made its way into any knowledgebase within Elecraft itself. One wonders how many hours have been spent by Elecraft staff and Elecraft customers ? and how many KAT500 and KPA500?s have been shipped back for repair ? because of this one issue. And that?s why I?m posting it here. I?d like to thank Bob and Dick from Elecraft for their prompt, professional, and thoughtful assistance in helping me to look at the anomalous behavior I?ve always seen, but never could quite pin down, with my KAT500/KPA500. And I?d especially like to thank Andy Durbin, K3WYC, for finally illuminating what was actually going on. Andy submitted a defect report last fall and hopefully Elecraft will prioritize it at some point. In the meantime, if you?re running a Kenwood rig and are contemplating adding the KAT500/KPA500 PowerCombo? be aware that there are issues. 73, Jeff K4EI From m.matthew.george at gmail.com Sat Mar 21 13:37:35 2020 From: m.matthew.george at gmail.com (M.

Has to be an unintentional glitch. That may depend on your RTTY software. By convention, MOST RTTY AFSK software (MMTTY, 2TONE, GRITTY) depends on the radio transmitting LSB, and that's how Elecraft radios do it -- the AFSK setting is LSB. Virtually all other digital mode software uses USB, and DIGITAL A in Elecraft radios is USB. Both AFSK and DIGITAL A take computer-encoded audio from the LINE IN. In AFSK-A mode, Baud rate and RTTY tone frequencies settings in the radio must match the frequencies sent by the computer. Other settings that can prevent RTTY from working are audio drive level from the computer and VOX. 73, K9YC From kc8wh.mh at gmail.com Sat Mar 21 14:04:52 2020 From: kc8wh.mh at gmail.com (kc8wh.mh) Date: Sat, 21 Mar 2020 14:04:52 -0400 Subject: [Elecraft] Elecraft KAT500/KPA500 PowerCombo only Partially Compatible with Modern Kenwood Rigs In-Reply-To: <9209E601-8EF6-4C6D-924F-174A82016F0B@earthlink.net> Message-ID: <5e765746.1c69fb81.83453.8e3c@mx.google.com> I noticed this issue exists when using the memory channels as well.?My solution was to remove the Kenwood cable, just hook up the ptt line and let the KAT/KPA 500s sense the frequency and make the adjustments on the fly.They are really, really quickMike KC8WHSent from my Verizon, Samsung Galaxy Tablet -------- Original message --------From: Jeff Hughes Date: 3/21/20 1:17 PM (GMT-05:00) To: elecraft at mailman.qth.net Subject: [Elecraft] Elecraft KAT500/KPA500 PowerCombo only Partially Compatible with Modern Kenwood Rigs Just a little public service announcement that the Elecraft KAT500/KPA500 PowerCombo is only partially compatible with modern Kenwood radios.? To whit? the PowerCombo works with VFO A, but not VFO B.Most modern rigs come with dual VFO?s, of course.? And many come with outright dual receivers.? This ability to quickly monitor and move between bands/frequencies comes in handy in a variety of scenarios.? And most of us happily bounce between these dual VFO?s without attaching any particular importance to one over the other.The problem lies with the KAT500, which reliably tracks VFO A? but which cannot track VFO B.? The upshot being that if you?re operating VFO A, the KAT500/KPA500 PowerCombo will work as expected.? But as soon as you toggle over to VFO B the KAT500 will manifest with clacking relays with every Tx on/off transition and the KPA500 will instantly fault with High Reflected Power if it is brought online in SWR conditions that required a tuned solution from the KAT500.Said differently, if you?re operating in conditions where native, un-tuned SWR is low ? where you don?t need the KAT500, in other words - the KPA500 works perfectly.? But as soon as you move to a frequency with a moderate-or-higher SWR ? a situation where you need the KAT500 to insert its tuned solution ? it cannot do so, and the KPA500 faults.? The behavior is independent of the best practices usually espoused for the KAT500? always operate in ?Manual,? ?train the tuner? to lock in inductor/capacitor settings in advance, and do that pre-tuning with 25-watts or more for greater accuracy.This VFO B problem applies to the Kenwood TS-590SG, TS-890S, TS-990S, and perhaps others.On their own, the KAT500/KPA500 PowerCombo are a remarkable addition to any shack.? Profound is the word I?ve often used to describe their impact.? However, the inability to use VFO B in conjunction with them is a pretty major failing.I have no information one way or the other, but I suspect the KPA1500 also suffers from this issue.Probably the thing that surprises me most is that this issue has apparently existed for years? and yet has not been socialized anywhere that I?m aware of.? Neither the Kenwood TS-890S User Manual nor the Kenwood TS-890S In-Depth Manual make mention that their VFO?s A and B implement slightly different character streams.? Elecraft?s KAT500 Automatic Antenna Tuner Owner?s Manual doesn?t mention that interfacing with Kenwood radios is a problem.? Fred Cady, KE7X (RIP), doesn?t mention it in his KPA500 Amplifier and KAT500 Tuner manual.? And it doesn?t appear to have made its way into any knowledgebase within Elecraft itself.? One wonders how many hours have been spent by Elecraft staff and Elecraft customers ? and how many KAT500 and KPA500?s have been shipped back for repair ? because of this one issue.And that?s why I?m posting it here.I?d like to thank Bob and Dick from Elecraft for their prompt, professional, and thoughtful assistance in helping me to look at the anomalous behavior I?ve always seen, but never could quite pin down, with my KAT500/KPA500.? And I?d especially like to thank Andy Durbin, K3WYC, for finally illuminating what was actually going on.? Andy submitted a defect report last fall and hopefully Elecraft will prioritize it at some point.In the meantime, if you?re running a Kenwood rig and are contemplating adding the KAT500/KPA500 PowerCombo? be aware that there are issues.73, Jeff K4EI______________________________________________________________Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:Elecraft at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.htmlMessage delivered to kc8wh.mh at gmail.com From jim at audiosystemsgroup.com Sat Mar 21 14:06:07 2020 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sat, 21 Mar 2020 11:06:07 -0700 Subject: [Elecraft] K3 doesn't work in AFSK-A mode but DATA-A does work.

For many years, I've used nothing but VOX to key my ancient K3s for SSB and all digital modes (RTTY and WSJT-X). Elecraft remember a lot of settings by band and mode, so once I've set them, levels have never been a problem for me. I'm using a good USB audio interface designed for semi-pro audio applications, a Tascam US100 (long discontinued, available at the great auction site). That improves decoding as compared to the built-in sound of many computers, but that's all it changes. BTW -- with a K3 and no built-in USB, using VOX rather than a "pull to ground" PTT reduces by one the number of cables between computer and radio, and a second USB port in the radio. 73, Jim K9YC From lists at subich.com Sat Mar 21 15:05:34 2020 From: lists at subich.com (Joe Subich, W4TV) Date: Sat, 21 Mar 2020 15:05:34 -0400 Subject: [Elecraft] K3 doesn't work in AFSK-A mode but DATA-A does work.

If one look at the schematic fr the KIO3B there is *no difference* between the KIO3B USB audio and the original KIO3 with an external soundcard. The sound card output is routed through the normally closed connections of the Line In jack. The *only way* one can have transmit with DATA_A and no output in AFSK_A is if the user has CONFIG:AFSK TX = FIL ON and the RTTY program's MARK tone does not match the MARK tone set in "PITCH". The easy way to confirm this issue is simply set CONFIG:AFSK TX = FIL OFF. Issues of VOX are a red herring ... one can use software command for PTT (TX; / RX; in MMTTY) or the DTR line on the CAT port CONFIG:PTT-KEY = DTR-off (both of which can be supported by MMTTY, and N1MM+). 73, ...

There are "gotchas" buried in MMTTY .ini files that can bite us if we use low- or mid-frequency audio tones. They assume that you use the default high tones, so if you do, there's no problem. But if you use low tones, as I do because they make it easier for my ear-brain to tune in RTTY signals, the two .ini files in the MMTTY directory must be edited to define the low or mid tones you've chosen. MMTTY.ini defines general setup, while USERPARA.ini defines all of the optional decoding algorithms, like "Fluttered Signals," "Multi-path," and so on. If you're using low or mid tones and these files are not edited, every time you change the decoding algorithm you'll be reset to high tones. (I learned this the hard way.) :) This is the line that must be changed to whichever tone you have chosen. It occurs multiple times in both MMTTY.ini and USERPARA.ini DefMarkFreq=2.125000e+03 Scientific notation is used to define the frequency -- 2.125 x 10e3 Hz -- 10e3 means x1,000, so 2,125 Hz. These files must be edited with a plain text editor (Notepad on a Windoze machine) and saved in the same directory and with the same filename and extension. FWIW, I'm using 2Tone as my primary RTTY software, because it can select between left and right channels for both RX and TX. MMTTY can select between left and right for RX, but not for TX (that is, it sends to both L and R). I do this because I do SO2R contesting, running both radios from the same computer. I use MMTTY for second decode windows on both radios. 2Tone, by a ham in the UK, has many advantages, including improved decoding and carefully shaped keying for minimum distortion. GRITTY is by VE3NEA, who wrote Skimmers for both CW and RTTY. I haven't tried it yet. 73, Jim K9YC From richarddnnr2 at gmail.com Sat Mar 21 18:00:35 2020 From: richarddnnr2 at gmail.com (Richard Donner) Date: Sat, 21 Mar 2020 15:00:35 -0700 Subject: [Elecraft] Keyoard help Message-ID: I just bought a new Windows 10 HP omen desktop and it came with a funky keyboard.

I found that the KPA500 periodically polls the Flex with an IF;FA;FB command and gets an FA and FB response from the Flex for the frequency currently designated for . The KAT500, on a separate USB port, waits for a broadcast from the Flex when there is a change in frequency. The Flex only broadcasts the VFO A frequency and it may take up to a second for the frequency info to arrive. Change bands too quickly and chaos may ensue with lots of red lights and relays clacking. It seems to me that an easy fix is to add the polling command to the KAT500 firmware, similar to the KPA500 firmware. I also think that I could build a modified null modem for the KPA500 with a couple of diodes to connect the KAT500 RX input and KPA500 RX input in parallel. Then, when the KPA500 polls for frequency info both the KPA and KAT will get the data. Sounds like a good "shelter in place" project. Bring on the schematics... And finally there must be a Raspberry Pi solution to periodically poll the Flex and then rebroadcast the information to both the KPA500 and KAT500. You would need three serial/USB ports. Might be an interesting Python project. Bring on the software... Similar solutions might be possible with the Kenwood radios. 73 Logan, KE7AZ -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Jeff Hughes Sent: Saturday, March 21, 2020 10:18 AM To: elecraft at mailman.qth.net Subject: [Elecraft] Elecraft KAT500/KPA500 PowerCombo only Partially Compatible with Modern Kenwood Rigs Just a little public service announcement that the Elecraft KAT500/KPA500 PowerCombo is only partially compatible with modern Kenwood radios.

But as soon as you toggle over to VFO B the KAT500 will manifest with clacking relays with every Tx on/off transition and the KPA500 will instantly fault with High Reflected Power if it is brought online in SWR conditions that required a tuned solution from the KAT500. Said differently, if you?re operating in conditions where native, un-tuned SWR is low ? where you don?t need the KAT500, in other words - the KPA500 works perfectly. But as soon as you move to a frequency with a moderate-or-higher SWR ? a situation where you need the KAT500 to insert its tuned solution ? it cannot do so, and the KPA500 faults. The behavior is independent of the best practices usually espoused for the KAT500? always operate in ?Manual,? ?train the tuner? to lock in inductor/capacitor settings in advance, and do that pre-tuning with 25-watts or more for greater accuracy. This VFO B problem applies to the Kenwood TS-590SG, TS-890S, TS-990S, and perhaps others. On their own, the KAT500/KPA500 PowerCombo are a remarkable addition to any shack. Profound is the word I?ve often used to describe their impact. However, the inability to use VFO B in conjunction with them is a pretty major failing. I have no information one way or the other, but I suspect the KPA1500 also suffers from this issue. Probably the thing that surprises me most is that this issue has apparently existed for years? and yet has not been socialized anywhere that I?m aware of. Neither the Kenwood TS-890S User Manual nor the Kenwood TS-890S In-Depth Manual make mention that their VFO?s A and B implement slightly different character streams. Elecraft?s KAT500 Automatic Antenna Tuner Owner?s Manual doesn?t mention that interfacing with Kenwood radios is a problem. Fred Cady, KE7X (RIP), doesn?t mention it in his KPA500 Amplifier and KAT500 Tuner manual. And it doesn?t appear to have made its way into any knowledgebase within Elecraft itself. One wonders how many hours have been spent by Elecraft staff and Elecraft customers ? and how many KAT500 and KPA500?s have been shipped back for repair ? because of this one issue. And that?s why I?m posting it here. I?d like to thank Bob and Dick from Elecraft for their prompt, professional, and thoughtful assistance in helping me to look at the anomalous behavior I?ve always seen, but never could quite pin down, with my KAT500/KPA500. And I?d especially like to thank Andy Durbin, K3WYC, for finally illuminating what was actually going on. Andy submitted a defect report last fall and hopefully Elecraft will prioritize it at some point. In the meantime, if you?re running a Kenwood rig and are contemplating adding the KAT500/KPA500 PowerCombo? be aware that there are issues. 73, Jeff K4EI ______________________________________________________________ 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 lrahnz at garlic.com -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From rocketnj at gmail.com Sat Mar 21 21:31:23 2020 From: rocketnj at gmail.com (Dave) Date: Sat, 21 Mar 2020 21:31:23 -0400 Subject: [Elecraft] Elecraft KAT500/KPA500 PowerCombo only Partially Compatible with Modern Kenwood Rigs In-Reply-To: <000001d5ffe7$607ef940$217cebc0$@garlic.com> References: <000001d5ffe7$607ef940$217cebc0$@garlic.com> Message-ID: <245B72D2-4266-4FE4-A937-F20E92E30A72@gmail.com> Logan, In the Flex USB cable setup just set the cables for Active TX Slice, so when you switch slices (vfo?s) the amp and tuner will follow the proper TX freq.

Then, when the KPA500 polls for frequency info both the KPA and KAT will get the data. Sounds like a good "shelter in place" project. Bring on the schematics..." You have to understand that KAT500 is designed to receive FA only. Making IF and FB available to KAT500 does not help because KAT500 does not decode or use these words. When a Kenwood rig is connected to KAT500 and KPA500 with the Elecraft serial cable then IF, FA, and FB are available to the KAT500. As stated above, KAT500 only listens to FA (the frequency of VFO A) and cannot track FB (the frequency of VFO B). If the design intent is to set KAT500 to the TX frequency before TX starts then IF, FA, and FB need to be decoded just as they are in the KPA500 and KPA1500. This requires a KAT500 firmware change. The alternate approach is to design you own decoder to derive the TX frequency from FA, FB, and IF (all three are needed to do it right) and send the result to KAT500 with the "F" command. 73, Andy, k3wyc From nr4c at widomaker.com Sun Mar 22 19:13:42 2020 From: nr4c at widomaker.com (Nr4c) Date: Sun, 22 Mar 2020 19:13:42 -0400 Subject: [Elecraft] K4 Update?

Add to that delays in shipping of parts from offshore companies due to delays at their factories and the worldwide reductions of air flights etc. which has made it very hard to get solid answers to delivery questions. I believe we have a number of weeks to go before we'll get reliable info we can believe in so we can update the first ship dates for the K4. A lot of that depends on how long the current state orders stay in effect. Fun, eh? It has also played havoc with our employees as they try to navigate the impact on their personal life of the statewide order to stay at home along with the shut down of schools. ( Plus the stress of frantically searching stores for toilet paper.. ;-) Our engineering team has transferred a lot of lab and development equipment home and is working hard there testing and adding features to the K4. Our Production logistics, Tech Support and Sales teams are also working the phones remotely. We're working hard in this difficult environment to keep the gears turning, albeit a little slower than we like. We were getting ready to film some K4 videos for an update that inclued showing the latest features when the statewide order hit. I'm slowly getting this back in process, in between all the other balls we have in the air. Stay tuned! I apologize for any delays we have responding here or to direct emails and phone calls. We really appreciate everyone's concern and understanding. The positive feedback we have received from each of you we've talked with recently, along with your continued orders, has been a real boost to the whole team here.

Message-ID: <9400C5C9-B07E-440D-9AE7-42C3D3D6FF37@comcast.net> At this point, I don?t think being concerned about when the K4 is going to arrive at our shacks so we can ?play radio? is a consideration. What we all need to do is wish Wayne and Eric well as they navigate uncharted waters. Elecraft is a great company that makes great products from great people. It?s not a big company like the Japanese radio producers. I suspect Wayne and Eric don?t have deep pockets and require products being shipped consistently to remain profitable. They have a large investment in development of the K4 including all the parts ready to go into the K4, but no product to ship. This is no picnic for them as they struggle to keep Elecraft going. I am sure all of us who have prepaid various amounts for a K4 have created a pool of money that hopefully will help. Let?s just hope that there are enough of us retired ?old farts? who will be able to weather the financial storm and not request a refund of deposits as I am sure will happen with working hams who have lost their jobs. I, for one, send my best wishes to Eric and Wayne and all the great Elecraft Team. When my K4 arrives is immaterial. 73, Terry, N7TB From rmcgraw at blomand.net Mon Mar 23 21:53:02 2020 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Mon, 23 Mar 2020 20:53:02 -0500 Subject: [Elecraft] Subject: The G5RV trivia In-Reply-To: <34a50330-dff2-9c45-9012-59d66126dfd6@Comcast.net> References: <34a50330-dff2-9c45-9012-59d66126dfd6@Comcast.net> Message-ID: The same antenna, although not named the G5RV, is described in the 1956 ARRL Handbook, Chapter 14, page 343.?? Fig 14-19 "Practical arrangement of a shortened antenna." ?? It may have been described in an earlier publication, however the 1956 Handbook is the earliest I have for reference. The description shows "A" as the length of 1/2 of a dipole where "2A" is the dipole total length and with the total length being less than 1/2 wavelength as shown in table 14-1.? The open wire feed line "B" is then 1/2 of "A".?? Therefore A + A + B + B becomes the length of the standard 1/2 wave antenna.? When the length of A + A is is greater than a 1/4 wavelength the effectiveness of the antenna is not changed. Table 14-1 shows the length of the antenna to be 135 ft with a feeder length of 42 ft. covering 3.5 - 28 MHz which uses parallel feed for 3.5 - 21 MHz and series feed for 28 MHz.???? A shortened version shows the antenna length to be 67 ft with 42.5 ft feedline.? In this case 3.5 MHz is series fed and 7 - 28 MHz is parallel fed. Regarding connecting a balanced feed line to the transmitter, Fig 14-21 (B) reference is made to do so using a pair of "balun" coils.?? This would imply a proper balun would contain two separate coils existing on two separate cores.?? The discussions by W8JI and DJ0IP would imply a single core will not be the correct design although it may contain 4 windings existing on a signal core.?? The original Heathkit balun, being two separate air wound dual winding coils would satisfy the requirement. Yes, more interesting trivia. 73 Bob, K4TAX On 3/23/2020 8:18 PM, Jan wrote: > I first learned of the G5RV Antenna back in early 1963 in Malaya ~ as > the Editor for the *M*alayan *A*mateur *R*adio *T*ransmitter > *S*ociety's /NewsLetter/ . ?

I had a 3 half waves in phase antenna for 40 meters, and it did the job nicely, but my first antenna was a 40 meter dipole fed with 75 ohm parallel feedline. It worked fine with my homebrew 75 watt 6146 transmitter with a Pi-Network output. The Pi-Network had a sufficient range to match it. I did not have an SWR meter at the time, so that is all I can say. The 3 half-waves in phase was fed in the center with true ladder line and the Pi-Network matched it too. Since modern transceivers want to see a 50 ohm load, the ATU takes the brunt of matching to the antenna and the task of achieving a good match is no longer by tuning to resonance (plate dip) and then loading for the desired amount of plate current. Those old days are gone. We could get radiation out in those old days just by looking at our meters and know that we had tuned up correctly. Such is not true anymore - there is just no proper comparison. You must tune the antenna/feedline to produce a 50 ohm load by use of antenna/feedline lengths and/or relying on a good ATU to bring the antenna load to near a 50 ohm match. An antenna analyzer is a great tool to use when working with antennas. A good link coupled antenna tuning unit can cover a large range (Johnson Matchbox is one example), and has many benefits that can be used today, but few know how to use it to advantage. 73, Don W3FPR On 3/23/2020 10:18 PM, Fred Jensen wrote: > Bob:?

No, but I intend to do this. It's certainly simple on the XG3 side; the possibly hard part is on your receiver's side. Beware that the XG3 output is a square wave. I am 99% sure that this means the stated power of e.g. -73 dBm is the power of the desired frequency, and the power of the third harmonic is not included in that. Certainly that is what you'd want for receiver testing as a ham receiver should be expected to not respond to the third (fifth, etc.) harmonic. If anyone has measured an XG3's output at various bands and power levels on real test equipment, seeing that data would be nice. The manual says +/- 1 dB typical for most ranges, and doesn't give absolute limits. Still, even about 1 dB is amazingly good for such an inexpensive device. Unless you want to buy proper lab gear with controllable output for vastly more money, the XG3 seems like the best thing out there. I've only used mine a little bit, but I'm very happy with it. 73 de n1dam From n3wm at yahoo.com Tue Mar 24 16:12:43 2020 From: n3wm at yahoo.com (Bill Mellema) Date: Tue, 24 Mar 2020 20:12:43 +0000 (UTC) Subject: [Elecraft] XG3 Signal Generator In-Reply-To: <2028516121.1477847.1585077439047@mail.yahoo.com> References: <2028516121.1477847.1585077439047.ref@mail.yahoo.com> <2028516121.1477847.1585077439047@mail.yahoo.com> Message-ID: <850805267.1460466.1585080763708@mail.yahoo.com> Bill, I've had my XG3 for a few years now and have never regretted buying it. Before I retired m business was in communications electronics. I worked for years with IFR which then became Aeroflex, out of Whichita. I had a Aeroflex 3920 communications analzer (which is still a high end piece of gear) at my office. I measured the XG3's output and frequency error and it was dead on with the Aeroflex 3920. I have used mine to calibrate receivers both new and vintage without a problem. Most of the use has been in the 2 -30 Mhz range, however I have used it on our VHF repeater to make quick receiver test. I have a few 50 ohm inline attenuators,3db, 6db, 10db I keep on hand. I also use a good quality step attenuator that allows the XG3 output to be attenuated as low as practical. I don't have the exact difference between the Aeroflex 3920 and XG3, but I can tell you it isn't worth the worry, the XG3 is that good. Hope this helps...

It is useful for a lot more than just calibrating the S-meter. When used with the XG3 Utility, it can serve as a full function signal generator with sweep capability. Yes, the output is a square wave, but as soon as the signal is fed into a receiver, the filters turn it into a sine wave. The only limitation of the XG3 is that it cannot do extremely low levels because the plastic case has some low level leakage - even a step attenuator is not effective at extremely low levels unless the XG3 is put inside a metal enclosure. I pressed my old HP8640 into service for any low level testing (like MDS testing). My mil-spec HP8640 would go down to -140dBm without leakage because it had all the internal shield boxes with all screws intact. 73, Don W3FPR On 3/24/2020 3:41 PM, Greg Troxel wrote: > Bill Smith via Elecraft writes: > >> Looking at buying the XG3 signal generator to calibrate S meters. >> Particularly thought it would be very useful to calibrate the S meter >> in the HDSDR SDR software I use now.?

Try removing the top 3 and bottom 2 screws and gently pry in the bottom slots just a quarter inch, then shove it back on. See if that fixes it. Also, tap DISP and rotate B to see the PLL1 voltages (Tech mode must be on). Go thru the bands watching the voltage, it should vary and be several volts. If you swap synthesizers, you might need to run the VCO cal, see manual for config item "VCO MD". Are you on Ant 1 or 2? (if KAT3 equipped). Did the radio get reset by accident? If so, the filters etc need to be setup, or load an old config file with the K3 Utility. If that radio has not been here, it will need a LOT of updates!! Suggest sending it in. Keith WE6R From: David Olean To: Elecraft Reflector Cc: Bcc: Date: Tue, 24 Mar 2020 16:57:52 +0000 Subject: [Elecraft] A broken K3 For all you tech gurus, I am trying to fix an old K3 that belongs to my brother. He has serious medical issues and I was hoping to fix his K3 so he can use it and be on the air in between chemo treatments. He is very isolated and a working ham rig would be a big help to him. I am not having much luck with tech support with all the virus concerns and work disruptions. Here is what is happening in his K3 SN: 378 No receive or transmit. I hear no band noise, just a bit of hiss with the volume turned to max. He was in the middle of a QSO and it just died. When you transmit, it acts like it is transmitting but there is no output. The digital readout indicates a frequency and it changes as you turn the big knob, but the K3 hears nothing and transmits nothing. If you change bands the rig changes bands and all looks OK as to frequency readout etc. I hear all the relays clicking, but no RX or TX anywhere. I see a 8.23 MHz signal at the RXIF cable on the RF board (J-81) from the KREF board. It is about 100 mv p to p. I do not see any signal on the TXIF cable going to the RF board (J-65) from KREF board. I checked at Pin 2 on P73 (The synthesizer) for any RF output from the VCO and I see nothing except some suspicious DC fluctuations that amounts to a jump of maybe 100 mv. It looks random and not normal. I should see several volts of RF here I think! I do see the 49.380 MHz signal in the KREF board. (J1 & J2) That part is working normally. This is telling me that I have a synthesizer problem. Are there things to check on the Synth board? Is there any typical failure mode that has shown up? Are the boards repaired, or must I buy a new synthesizer board? This is an original synthesizer board, not a new design K3S board. I have been waiting for days to get any tech support response. Any help would be appreciated. 73 Dave K1WHS From dave at nk7z.net Tue Mar 24 20:18:31 2020 From: dave at nk7z.net (Dave Cole) Date: Tue, 24 Mar 2020 17:18:31 -0700 Subject: [Elecraft] K3S and Winlink In-Reply-To: <16678D71-05F4-4501-89E4-76EE035C64AA@mac.com> References: <81F150FF-D6E8-47FE-92E1-84351B62B6F8@mac.com> <90db128b-496a-a0da-c89f-30f6997ce071@nk7z.net> <16678D71-05F4-4501-89E4-76EE035C64AA@mac.com> Message-ID: Pretty much...

I was excited by how nice it looked and got a thrill setting up the soldering iron to install the phono plug. All done soldering; it's a simple job so no need to check out the connections with a meter. Plugged into the K3s, test mode, CW mode.....what the heck is that odd warble sound? How could I mess up a simple soldering job. Must have plugged the key into the wrong slot...nope it's in the paddle slot; where's my meter...mmm, ok scavenger hunt for the meter; didn't find the meter; let's verify settings, everything looks good; search again for the meter.... found it!! Interesting....plug wiring appears to be correct.. plug the key back in.. same warble tone. Ugh.. wife calling for dinner.. shut the rig down, then power supply.....go eat. Back from dinner, power up, same issue.. it's night time, let's check 40m...odd, the Frequency shows 4xxxMHz... changed band to 40M, test mode, CW, VIOLA!!! Sounds sweet! I got a chuckle out of this.

You can feed balanced lines from taps placed equally out from center on the both coils. The center of the two coils is common (ground), and unbalanced loads can be fed between the tap on one coil and the common center connection. The Johnson Matchbox is a bit different in that it uses a differential variable capacitor to adjust the electrical position of the coil taps. 73, Don W3FPR On 3/25/2020 10:32 AM, Angel Garcia wrote: > Don, is this comment about unbalanced vs balanced line tuners, or something > specific to use of a balanced line tuner? > Angel wa2vuy > A good link coupled antenna tuning unit can cover a large range (Johnson > Matchbox is one example), and has many benefits that can be used today, > but few know how to use it to advantage. > From k6sdw.usa at gmail.com Wed Mar 25 11:00:38 2020 From: k6sdw.usa at gmail.com (Eddy Avila) Date: Wed, 25 Mar 2020 08:00:38 -0700 Subject: [Elecraft] KX3 drift question Message-ID: I solved my KX3 drift problem, it wasn't electrical but rather mechanical....reading in the manual about the VFO I increased the resistance to the knob spin and *voila* no more drift!

It's been updated with new synths and a new KRX3A plus it was updated some years ago before I got it and has most of the factory mods, though not the gold pins. If you search the archive here on my callsign you can see what I posted. Briefly I had first a loss of TX and some months later a loss of RX and TX. Both faults were traced to 0.1uF decoupling capacitors on the K3REF board going leaky and puling bias voltages down such that they would not switch the various circuits/signals.? In the first case it caused loss of the TX bias voltage so the diode switching was not working. In the second case it was causing loss of second L.O. injection which of course made for a rather quiet receiver as well as no transmit. Good luck, for sure you can fix it or get it fixed. 73 Martin, HS0ZED On 25/03/2020 21:49, David Olean wrote: > Hello Jack, I have responded to Keith and am following his directions. > He had lots of good info for me to try, and I am grateful for that. > > Dave, K1WHS > > On 3/25/2020 5:48 AM, Jack Brindle wrote: >> David; >> >> Go back and re-read the message from Keith Trinity.

I have them on both the K3 and KX3. But dimpled knobs exhibit out-of-roundness since material has been removed to form the dimple.? When spun, such knobs will back-lash at the end of their travel. My ultra sophisticated procedure for perfect adjustment is to increase the knob's resistance to spinning until there is no more back-lash as indicated on the frequency display set to the smallest Hertz.? The knob is still free-spinning but when it stops the frequency stops. 73, Kent?

Basically, just stick the components on the PCB and solder. The KRC-2 is a bit more more complex, some mechanical pieces need to be assembled in the correct order or you get to remove them to solder in some components. I was alerted to this because I read the assembly manual prior to starting. Doh! The assembly was straight forward, reminded me of the old Heathkit days except Heathkit had more assembly sketches. I learned about cold solder joints with my first Heathkit, an AR-2 SW RCVR I built when I was 7 YO. I had a TV repair guy go over the radio and show me what I had done incorrectly and how to prevent them in the future. A great resource. Plus, I got all his old radio and TV units that were deemed unrepairable to build a parts stash. I plugged it in and no smoke escaped. The check-out procedure was straight forward. All A-OK. I boxed it and sent it to its new home. --- 73 de W3AB/GEO From k6dgw at foothill.net Thu Mar 26 15:26:05 2020 From: k6dgw at foothill.net (Fred Jensen) Date: Thu, 26 Mar 2020 12:26:05 -0700 Subject: [Elecraft] OT James Clerk Maxwell In-Reply-To: References: Message-ID: <1b8fbc7a-0b77-7d45-3ee4-ddacf7a4c338@foothill.net> Yes.? However, Oliver Heaviside had the advantage of both vector calculus and operational mathematics which he sort of invented.? Maxwell did it "old school." Regardless of who you favor, the theory took on new meaning for me when a professor pointed out ... "We can measure electromagnetic radiation from it's earliest beginnings and many billions of light years away in any direction we choose and it always obeys Maxwell's analysis to whatever precision we can muster."?

I have been running FT8 at around 5 watts recently and I see it getting up to 51C. At what point should I stop operating and let it cool down? I love my KX2 and don't want to damage it. I do know that these are used in fields by many so perhaps I am just being paranoid. 73 de KJ5T From jh3sif at sumaq.jp Thu Mar 26 22:20:59 2020 From: jh3sif at sumaq.jp (Keith Onishi) Date: Fri, 27 Mar 2020 11:20:59 +0900 Subject: [Elecraft] KX2 Safe Operating PA Temperature In-Reply-To: References: Message-ID: I do not have KX2 but KX3. KX3 internally set a PA temperature limit at which KX3 automatically reduces power output. Assuming that KX2 and KX3 are very similar, unless your KX2 automatically reduces power output, the PA temperature is within the safe range. I think running FT8 with 5W output is safe since I have made many FT8 QSOs with 5W. You may attach any 3rd party heatsink if you want to feel safe. 73 de JH3SIF, Keith > 2020/03/27 10:09?Steve Anness ????: > > This question was posed last October by another on the reflector in regards > to the KX3 but does not look like there was a response.

It was an oldie with a serial number in the 300s and it died on him in the middle of a QSO. It has been dead for about six months and he is not in the best of health, so I figured I would try to fix it for him.? Elecraft Tech Support came through even with all of the Virus conditions rocking the entire economy. Symptoms were no TX or RX, but everything seemed to be working as relays clicked as you changed bands, and the dial indications seemed OK. I traced the problem to a missing synthesizer signal to the first mixer and also the 2nd mixer on TX.? I tried swapping out the synthesizer, but had no luck as the 2nd synthesizer did not work either.? With the expert help and advice from Tech Support I found that my synthesizer was missing the 8 VDC on one of the connector pins. Checking the 8 volt rail, the resistance to ground seemed OK, so I removed the 8 V regulator and supplied 8 volts from an external current regulated power supply.? It pulled about 230 ma at 8 volts. The K3 took off and started working again with 8 volts supplied. I had to do another synthesizer CAL, but after doing that, the rig is good to go on all bands. I was hoping that I had a new 8 volt regulator in my junque box. After an exhaustive search I found everything BUT and 8 volt regulator, so I will have to order one. I'll also get some upgrade kits from Elecraft to bring K3 #387 into the 21st century. Gold pins are on top of the list.

When I used to run digital modes on the KX3, the radio would drift a bit as it heated up. I got one of the XG50 reference oscillators, and went through a temperature compensation profiling procedure, and after that it worked very well. I guess you already know with Elecraft radios that setting the levels works differently to many other commercial radios -- often you'll see procedures where you use the audio input drive to control the transmitted power and saying to avoid ALC, but those procedures and not appropriate for Elecraft -- there you need to set the input level (on KX3 think it was something like 4 bars on the "ALC" meter) then control the output power using the power output knob. Someone else on this list probably has more current information than I which pertains to the KX2. 73, Matt VK2RQ On Fri, 27 Mar 2020 at 13:54, Steve Anness wrote: > > Thank you for the feedback.

For the record the time that it got that hot running 10 watts was SSB and I was doing a continual (recorded) CQ. I only run digital modes at 5 watts or less. Again I appreciate all the feedback, I have KX2 number 617, bought it in June 2016 but it sadly it gets neglected at times, doing a bit more FT8/FT4 though now, especially since i am stuck at my apartment. 73 de KJ5T On Fri, Mar 27, 2020 at 1:05 AM Mooneer Salem wrote: > FWIW, my KX3 handles 15 watts digital with no issues as far as I can tell. > I did the temperature compensation and have a third party heatsink, though. > I haven't looked too much at third party heatsinks for the KX2 but I > imagine I'd probably want to follow that 50% advice even with one installed > simply due to its physical size. > > -Mooneer K6AQ > > On Thu, Mar 26, 2020, 10:47 PM Joan via Elecraft > > wrote: > > > The KX2 will automatically fold back its power (responding to > temperature) > > to prevent thermal runaway or damage to its finals > > > > That being said, it is routinely recommended that when running any 100% > > duty cycle mode (e.g. typical digital text modes or FM Phone) one reduces > > RF output to 50% of rated output > > > > 73 de KX2CW > > Joan > > > > Darmok and Jalad at Tanagra, said Piglet. > > Shaka, when the walls fell, said Pooh. > > > > > On Mar 26, 2020, at 18:09, Steve Anness wrote: > > > > > > This question was posed last October by another on the reflector in > > regards > > > to the KX3 but does not look like there was a response.

I bought a Keyspan adapter instead and installed the Keyspan driver. Over the years, I updated the driver when I updated the macOS. The Keyspan stopped working with macOS Catalina, and Keyspan won't update the driver to be compatible with Catalina. I just bought a new KUSB and tried to install the FTDI VCP driver. For whatever reason, yesterday the driver installer wouldn't work. So I installed the FTDI D2XX driver. The K3 Utility still wouldn't work. Then came a chain of emails via the reflector. I uninstalled the D2XX driver, hoping the macOS Catalina native driver would take over. Nope. Just for chuckles, I tried again to install the VCP driver. Today the installer worked. After a reboot, the K3 Utility is working just fine. Whether it was the Keyspan driver or the D2XX driver or macOS Catalina causing the problem, that's beyond my expertise and interest.

Loading my saved configuration, saved after the problem occurred, created the same problem, no HI-Lo in SSB only on Data and AM. I've now doe a full manual setup of all my filters and modules, I had that info to hand, and saved the current full working configuration.

Interesting question, but there are huge differences in events: 1. The NASCAR race itself is very public and the results are known at the end of the race (contest). Such races are publicized through news media so that even those that don?t watch the race live can easily find out the results after the race. As part of the publicity, each team is described as a ?Ford?, ?GM?, ?Honda?, team etc. even though the cars themselves are indistinguishable except for the label that is slapped on them. NASCAR fans indeed have ?brand loyalty? and may well be influenced by racing results. 2 An amateur contest is conducted in closed hamshacks running for significant periods of time (over a weekend) and no one necessarily knows who is competing until logs are submitted. Generally, no one knows (including the contestants) the results for a month or more after the event. And when the results are announced, the contestants are described by their name/call, location and perhaps club affiliation. No one is highlighting their equipment unless a photo is included in the article providing the contest results that provides a glimpse of their shack. Consequently, I seriously doubt that there are peaks in sales due to the results of specific contest events themselves. That said, we are seeing some equipment touted based upon advertising conducted by the manufacturers themselves: 1. Flex Radio touts their ?SO2R? solution for contesters and others highlighting the ease of Flex products being able to operate SO2R with relatively minimal wiring/cabling. This includes having contesters explaining how they're benefiting competitively from Flex product offerings. 2. Manufacturers are supporting DXpeditions where the manufacturers themselves publicize their support for a particular operating group from some rare location. Both Elecraft and Flex have done this. In addition, the DX Team publicly highlights the financial support provided by major donors, including equipping their team with the equipment that is utilized. I can?t say that there is a direct correlation between specific contesting and DX events as having a correlation with amateur radio equipment sales. However, it is probably fair to say that manufacturers are now paying attention to contesters in helping to determine the features/bells & whistles being put into their products. Flex in particular has been doing that with their SmartSDR development. Their transceivers and PGXL amplifier are based in part of meeting contester preferences. Their strategy is presumably based in part of two factors: 1. Contesters are spending real $$$ on their stations to develop a competitive edge. When your focus is on the contest and not the wallet, they?re more likely to spend money on technology that will enhance their capabilities or provide ease of finding and making QSOs. 2 There is indeed a ?trickle down? impact where the capabilities introduced to support contesters becomes available to other amateur operators. Again, Flex touts their focus on contesters because the contesters are in a sense underwriting the development effort by being ?early adopters.? However, once developed, features/capabilities become available to a wider audience who may be interested in taking advantage of particular new features that appeal to them. BTW, this isn?t necessarily a new phenomena. There has been plenty of technology developed for other markets over the past 10 years or so that have been introduced into amateur radio products (e.g. DOD/NSA-> amateur radio). Software Defined Radio has grown tremendously because organizations with ?real money? underwrite technology and product development that later gets introduced into the amateur radio market.

They all are as equal as possible with the same antennas same locations etc. Contests for a number of years at K4VX multi-multi and I observed and learned the operator was the winning key. Have seen good operators sit down with a "poor" radio and make double the contacts another op with the best radio available made.

If you survey the most competitive contesters about their favorite (i.e., most effective) SSB radio you probably won't find a single contester that favors the K3. In fact, they would favor any of other manufacturer over Elecraft. CW is a different story where the K3 really shines as the favorite radio among the most competitive contesters. 73 Frank W3LPL ----- Original Message ----- From: "Wes" To: "Michael Walker" Cc: "Elecraft at mailman.qth.net" Sent: Sunday, March 29, 2020 3:05:58 PM Subject: Re: [Elecraft] The Big Three...

The K3 on SSB sure has its faults. What say you on the top SSB rigs? Also, since no Dayton and the idea of a contest that weekend is a good idea. But maybe we should consider some kind of virtual hospitality suite so we can have a beer or two plus chat.

Each of my six stations has two radios, usually a K3 and a "not K3," usually a Yaesu FTdx5000. During CW contests our "run" operators usually favor the K3, during SSB contests our "run" operators NEVER favor the K3. 73 Frank W3LPL -----Original Message----- From: tony.kaz at verizon.net Sent: Sunday, March 29, 2020 12:40 PM To: 'donovanf at starpower.net' ; 'Elecraft at mailman.qth.net' Subject: RE: [Elecraft] The Big Three...

Also, since no Dayton and the idea of a contest that weekend is a good idea. But maybe we should consider some kind of virtual hospitality suite so we can have a beer or two plus chat.

The K3 design is dated, all of the other top manufacturers have introduced much higher performing SSB radios in recent years. The K3 was a revolutionary design when it was introduced many years ago, but no more. Hopefully the new K4 will change the game in Elecraft's favor once again, especially for the most competitive SSB operators. 73 Frank W3LPL ----- Original Message ----- From: "Charles Sells" To: "K9FD" Cc: Elecraft at mailman.qth.net Sent: Sunday, March 29, 2020 4:39:40 PM Subject: Re: [Elecraft] The Big Three...

Message-ID: Well I have been sending CW for 70 years now. I am not the most accomplished Morse operator you will copy. But I wonder why someone would think it is improper procedure to move your wrist ? I have watched musicians play guitars and bass instruments. They all move their wrists. I am not a musician myself. But when I do send Morse I get into a rhythm like musicians do. With 70 years of experience I have evolved into a competent operator. Many years ago my XYL told me that I also send Morse with my vocal cords when i send CW. She noted that when serving me food during my contesting. She was correct. My speed might be higher than the average Morse operator. I started with a straight key in 1950. Went to a Vibroplex bug in 1954. Up Graded to an electronic keyer in 1966. During that 16 year period I always moved my wrist. I probably own two dozen keys and paddles. I don?t get over 35 wpm very often. But if I find that rare operator who can copy QRQ I can crank it up. I can send with either hand too. The one thing I do is not think about what I am doing. It is all reflexes. I am a member of several CW oriented clubs. The German High Speed operators are excellent users of Morse. Google that organization. To say that moving your wrist is incorrect procedure might appeal to some. Not me. By the way I decided years ago to put a paddle on the floor and use my foot. Really! That allowed me to use both hands. I have not done that for some years. I think I can still do that. using your feet: LF operating. In my case it was RF (right foot). That was just a challenge. It did take some practice. I sure beats some of these current modes which do not require any operator skill. 73 Jim W9VNE/VA3VNE Sent from my iPhone From jsdanehy at gmail.com Sat Mar 28 22:24:58 2020 From: jsdanehy at gmail.com (Jim Danehy) Date: Sat, 28 Mar 2020 22:24:58 -0400 Subject: [Elecraft] Sending CW unconventionally Message-ID: <9DC454EA-DAF5-4772-87EE-EA0ABBBA34F6@gmail.com> If you think this is unusual, it is.

Arguably more choices than ever before. Rather than getting into detailed discussions about specific performance parameters, let me just suggest that you do what we do at W3LPL during every SSB contest. Set up a K3 for SSB using the best parameter settings you're aware of. Then set up any other top-of-the-line radio next to it. The comparison in received SSB audio quality is stark. When digging weak -- often distorted -- signals out of noise and extreme adjacent channel interference, overall receiver audio is extremely important. Do the same test with SSB transmitted audio quality by setting up a "blind test." Use the best K3 parameter settings you're aware of. Then set up any other top-of-the-line radio next to it. Ask several very competitive SSB contesters to listen to transmissions from both radios. Don't tell them advance which radio is which, just tell them Radio A and Radio B. I guarantee you that no competitive contester will prefer K3 transmitted SSB audio over any of the other top-of-the-line radios in a blind test. It won't be long before we can have some run running the same tests with the K4. 73 Frank W3LPL ----- Original Message ----- From: "Carl Yaffey" To: donovanf at starpower.net, Elecraft at mailman.qth.net Sent: Sunday, March 29, 2020 5:35:15 PM Subject: Re: [Elecraft] The Big Three...

We're busy adding new capabilities to the K4 and testing it in real-world conditions. (If it weren't for the lock-down, I and other early users would still be inviting operators over to try it. Previous demonstrations have led to amazement over the sound of the receive audio quality, among other reactions.) With its new, faster DSP, versatile architecture, large display, and essentially unlimited code space, the K4 can offer features that go far beyond what we've been able to offer before. Here's a sampling of what this will mean for SSB users: *** Optimal audio The K4's RX and TX passband in SSB modes can be configured to be flat from below 50 Hz to over 4 kHz, with none of the drawbacks of crystal filters (delay, ripple, passband edge effects). Easy to use graphic TX/RX EQ and other bandwidth controls allow the operator to tailor the response per-mode and for different microphones. The overall effect is full, rich audio in both transmit and receive -- the latter in full stereo. Wider transmit and receive bandwidths can also be configured for digital audio modes, ESSB, and AM, at the operator's discretion. *** Exceptional ALC performance The K4 uses a new ALC system designed to completely eliminate power overshoot and varying loop dynamics. This makes it both easier to adjust and more compatible with external amplifiers. *** Multi-parameter transmit metering In voice modes, the K4 provides clear bar graph displays of all four transmit parameters simultaneously: power output, SWR, ALC, and compression (processing level). Real-time numeric readouts of power, SWR, supply voltage/current, and PA temperature are also available. *** Foolproof split transmit indication You'll never lose track of whether you're in SPLIT mode with the K4: all four transmit bar graphs are grouped either on the left (non-split, i.e. VFO A = TX) or right (split, VFO B = TX). TX icons are also clear and unambiguous. The K4 also allows full cross-band/cross-mode operation in both split and non-split. *** Versatile audio I/O There are mic and headphone jacks on both the front and rear panels. Some operators prefer to use the rear panel connections to avoid cluttering the operating position. Audio for both voice and data modes can be either analog (LINE in/out) or digital (via USB or Ethernet). *** Large DVR memory The digital voice recorder draws on the K4's large pool of flash memory, allowing virtually unlimited expansion for both transmit and receive purposes. There are also new, easy to use playback controls. *** Redesigned PA stages All transmit stages have been upgraded, with improved biasing, parametric monitoring, and T/R sequencing. Hardware is also in place to support closed-loop amplifier IMD optimization, both internally and externally. *** Support for future operating modes With DSP and MCU horsepower to burn, we'll be able to add new voice and data modes in the future (and even new bands). The K4 is designed from the ground up for extensibility in both hardware and software. 73, Wayne N6KR From k6dgw at foothill.net Sun Mar 29 14:40:22 2020 From: k6dgw at foothill.net (Fred Jensen) Date: Sun, 29 Mar 2020 11:40:22 -0700 Subject: [Elecraft] Not moving your wrist sending CW ?

I am not myself a contester except on Field Day. Most performance measurements for the K3(s) show it still in the top group in terms of ability to hear weak signals adjacent to a stronger signal, an important measure for performance in a contest. Until recently they were in the #1 position or near #1. Now some newer rigs have barely exceeded the K3S performance by a very small amount, we will see how the K4 performs, I suspect Elecraft will be at the top of the heap again. I am not sure you can actually tell the difference in performance at this level. The main criticism as I understand it with SSB is that the K3 produces a harsher sound on SSB than some other rigs. While this will not interfere with your ability to operate, it can irritate the listener over time. You can moderate that somewhat through EQ settings, but I do think that some other rig manufacturers have been noted for more pleasant sounding audio. For me, long ago I found some really nice speakers (Sounds Sweet, no longer in business) that do an excellent job of making my K3 with updated synthesizers sound pleasant. I am looking forward to the K4 getting released and tested. I will probably not be in the market to purchase anything major until this coronavirus situation stabilizes and the economy gets back to normal. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Dauer, Edward Sent: Sunday, March 29, 2020 10:48 AM To: elecraft at mailman.qth.net Subject: [Elecraft] K3 on SSB Previous posts suggest a consensus, or at least a widely-held opinion, that the K3 is below par on SSB. I have owned one for years, using it more than 95% on CW, and on SSB in only one contest and a few casual ragchews and nets. In what ways is the K3 inferior to others on SSB? Yes, this is a question, not an argument. And is the K4 designed to correct whatever those flaws may be? I have not yet ordered a K4. Knowing this info would be helpful to that decision.

The only place I know that Morse was sent using "fingers only" was with iambic/squeeze keying using an electronic keyer.

I moved to a bug where I was taught to roll the forearm (confirmed after the fact by my wife's grandfather who was a long time Western Electric landline operator/station manager) to a single paddle TO keyer and eventually to a dual paddle keyer.

Several of the top contesters are sponsored by some of the radio companies. The winner in the 2014 WRTC was sponsored by Icom as were many others. The same was true in 2018. Of course, they get the best radios, delivered at the competition. Thus the radio choice tends to be biased by the fact that the contesters may not be paying for their radios, or having to hand-carry them to the competition. As for the winners, we have seen many times that the contesters who are most familiar with propagation in the area where the competition is held will win. This was true in Massachusetts, Germany, and will undoubtedly be true in Italy. The top guys travel to the areas to get a feel for propagation, but having experience there for a long time makes a huge difference. In WRTC, it isn?t so much the radio, but rather the experience in the zone that matter the most. Radios, logging software, antennas, etc are pretty much even. The ops themselves make the big difference. 73!

They didn't teach us to send, other than after we passed 18 groups (yes, 5 leter/number groups, not English words) per minute copying on a "Mill" they gave us a 4 hour class on sending with a hand key. To pass that class we had to send a paragraph of text which was recorded in the morning and then in the afternoon we had to copy back the text we sent and get 75 percent perfect copy to pass. THAT is extremely difficult when you learned to copy 5 letter/number groups and then the sending test was a paragraph of English and your own sending to boot! I taught myself higher speed sending using a TO keyer and a Vibroplex single lever paddle (Iambic keying hadn't been invented at that time). I didn't get to where I could get my ham license until I got to Japan in 1963 and took the old "Conditional" test. Once I had my license I bought a Vibroplex bug and again taught myself to use it. I do roll my wrist slightly, and for me that is very comfortable. I also taught myself (took a couple years to master) to switch back and forthe between paddles and the bug, a skill I maintain to this day and I'm turning 78 in a few days. I can still copy 60 wpm or so in my head but with the bug or paddles, my comfortable sending speed is between 25 and 30. My pet peeve these days with the newer ops that actually can send CW is they call CQ and then end the CQ sequence with "KN" and then wonder why nobody answers them - LOL.

They didn't teach us to send, other than after we passed 18 groups (yes, 5 leter/number groups, not English words) per minute copying on a "Mill" they gave us a 4 hour class on sending with a hand key.? To pass that class we had to send a paragraph of text which was recorded in the morning and then in the afternoon we had to copy back the text we sent and get 75 percent perfect copy to pass.? THAT is extremely difficult when you learned to copy 5 letter/number groups and then the sending test was a paragraph of English and your own sending to boot! I taught myself higher speed sending using a TO keyer and a Vibroplex single lever paddle (Iambic keying hadn't been invented at that time).? I didn't get to where I could get my ham license until I got to Japan in 1963 and took the old "Conditional" test.? Once I had my license I bought a Vibroplex bug and again taught myself to use it.? I do roll my wrist slightly, and for me that is very comfortable.? I also taught myself (took a couple years to master) to switch back and forthe between paddles and the bug, a skill I maintain to this day and I'm turning 78 in a few days.? I can still copy 60 wpm or so in my head but with the bug or paddles, my comfortable sending speed is between 25 and 30. My pet peeve these days with the newer ops that actually can send CW is they call CQ and then end the CQ sequence with "KN" and then wonder why nobody answers them - LOL.

Sending with a semi-automatic key, a.k.a, bug, is significantly different than sending with a paddle connected to a keyer. The keyer is supposed to make the dit-dah ratio and spacing correct. The length of the elements is controlled and timed electronically. With a bug the length of a dah is controlled by the operator and the dit length by the vibrating pendulum. I learned on a bug but now favor the paddle/keyer combination.

Its very difficult to remove bias from the test and evaluation process. Inevitably the owner of a new radio, antenna or any other new capability will be biased toward the new investment.

Using ?KN? ?K? = ?over?. Sending just ?K? at the end of your over leaves the door open for other stations to break in. If you don?t want to be interrupted, send ?KN?. ?KN? means that you want to hear ONLY the station whose callsign you just sent (= ?go ahead, others keep out? or ?over to you only?), in other words: no breakers at this time please. ?KN? is mainly used when chaos is around the corner. A possible scenario: different stations are coming back to your CQ. You are decoding one partial call and you send: ?ON4AB? DE G3ZZZ PSE UR CALL AGN (again) K?. The station ON4AB? answers you, but in addition several other stations call simultaneously, making it impossible to copy his call. The procedure is to call ON4AB? again and end your call with ?KN? instead of ?K?, this to emphasize you only want to hear ON4AB? come back to you. Example: ?ON4AB? DE G3ZZZ KN? or even ?ONLY ON4AB? DE G3ZZZ KN?. If you are still short of authority on the frequency you may try ?ON4AB? DE G3ZZZ KN N N N? (keep some extra space between the letters N). Now you are really getting nervous...

The correct procedure is to use your wrist as a "spring". Failure to do so will soon cause a condition known as a "glass fist". I'm also a musician, so one foot serves as a metronome to establish a very even sending rate. TRIVIA ... if confronted with a brief need to use a "backwards" set of paddles, just turn it around and reach over the top.

Sending on a bug is quite different from sending on a paddle + keyer. The op needs to be more physical with a bug in order to inject kinetic energy into the mechanism. Setting it up like a paddle and trying to work it with fingers only will not go very well. As for copying, there is nothing worse than words run together in combination with pauses in the middle of words-- probably at least as common with paddles as bugs. Any sending variations other than that are merely "accents". (Admittedly, there is no accent with paddle + keyer-- only mistakes.) 73, Drew AF2Z On 03/29/20 17:16, marvwheeler at nwlink.com wrote: > Copying code sent with a semi-automatic key is significantly different than copying code sent with a keyer and paddle.

The latest Flex radios are almost shockingly good, but all of the top-shelf modern radios are significantly better performers than the 12 year old K3 or even the K3S. We're discussing the most demanding situations affecting SSB transceiver performance: weak -- often distorted -- SSB signals surrounded by much stronger adjacent channel QRM. For much of the time on 20 and especially 40 meters the adjacent much stronger signals overlap well into the receiver bandwidth. Typical spacing between SSB signals is only 1.5 kHz, if you're lucky its 2.0 kHz and only rarely 2.5 kHz or more. This situation is rather unimportant for the casual contester, but its a game changer at the upper levels of serious SSB contest competition. I have not made technical measurements of K3 SSB transmitter and receiver performance nor do I have the capability to do so. I suspect the more modern designs have improved the dynamic response of their entire receiver and transmitter chain in ways that can't be captured by simple static performance measurements such as frequency response, dynamic range and IMD. 73 Frank W3LPL ----- Original Message ----- From: "Jim Brown" To: elecraft at mailman.qth.net Sent: Monday, March 30, 2020 12:32:52 AM Subject: Re: [Elecraft] The Big Three...

The vast majority of transceiver users have no concerns about the performance of their transceiver under these conditions. We're discussing the most demanding situations affecting transceiver performance: weak -- often distorted -- SSB signals surrounded by much stronger adjacent channel QRM. For much of the time on 20 and especially 40 meters the adjacent much stronger signals overlap well into the receiver bandwidth. Typical spacing between SSB signals is only 1.5 kHz, if you're lucky its 2.0 kHz and only rarely 2.5 kHz or more. This situation is rather unimportant for the casual contester, but its a game changer at the upper levels of serious SSB contest competition. For transmitted SSB signals we're concerned about situations where our transmitted signal is relatively weak and surrounded by much stronger adjacent channel QRM. The adjacent signals usually overlap well into the transmitted signal bandwidth and the other operator's receiver has much lower performance that our top-of-the-line radio. 73 Frank W3LPL ----- Original Message ----- From: "Clay Autery" To: elecraft at mailman.qth.net Sent: Monday, March 30, 2020 5:20:31 AM Subject: Re: [Elecraft] The Big Three...

Soon after he got his Flex 6700, his two key impressions were 1) it was the best radio he'd ever owned; and 2) the designers of the radio and it's software/firmware didn't have a clue about USING radios on the air. #2 was so bad that they didn't even understand the problems. Thankfully, guys like N6WM, K9CT, and I'm sure others, stepped in to educate them. :) I'm not a digital guy, but having worked in pro audio most of my professional life, some concepts have rubbed off. If I were to speculate on the shortcomings of the K3/K3S you've noted, it would be that the system wasn't designed with enough bits and bandwidth. But that all depends on the parts you can buy for a product that must sell for a price that customers can pay, and, as you've noted, those design decisions were likely made in 2006.

Also true in U.S. Army radiotelephone procedure, at least how we operated in the Signal Corps in the '70s and '80s when I was in. Never heard or was taught 'words twice'. One would realize (with experience) when key parts of the transmission should be said twice due to noise or other difficulty with the channel, usually because of being asked to 'say again' a few times. Asking for a retransmission: 'say again your last transmission' 'say again all after' 'say again all before' The response would be: 'I say again ...' There is also 'I spell', when the word(s) weren't being received correctly. This was published in 'Allied Communications Pub 125: Communications Instructions -- Radiotelephone Procedures' (ACP 125), so these procedures should be somewhat standardized across NATO forces. 73, Steve K6ZX From donovanf at starpower.net Mon Mar 30 02:22:17 2020 From: donovanf at starpower.net (donovanf at starpower.net) Date: Mon, 30 Mar 2020 02:22:17 -0400 (EDT) Subject: [Elecraft] The Big Three...

Its probably not a coincidence that all of the top-shelf modern radios have a leg up on the K3 in the most severe competitive contest environments Think about what less than 14 years of improvement brought to the market in the post-World War II environment and the vast performance differential between the offerings from Collins and every one of their competitors: - 75A-1 1947 - 75A-4 1956 - KWM-1 1957 - S-Line 1958 Its amazing that the amateur radio HF transceiver market continues to drive significant performance improvements after all these years, just as it did from the earliest days of HF radio. 73 Frank W3LPL ----- Original Message ----- From: "Jim Brown" To: elecraft at mailman.qth.net Sent: Monday, March 30, 2020 5:45:21 AM Subject: Re: [Elecraft] The Big Three...

Soon after he got his Flex 6700, his two key impressions were 1) it was the best radio he'd ever owned; and 2) the designers of the radio and it's software/firmware didn't have a clue about USING radios on the air. #2 was so bad that they didn't even understand the problems. Thankfully, guys like N6WM, K9CT, and I'm sure others, stepped in to educate them. :) I'm not a digital guy, but having worked in pro audio most of my professional life, some concepts have rubbed off. If I were to speculate on the shortcomings of the K3/K3S you've noted, it would be that the system wasn't designed with enough bits and bandwidth. But that all depends on the parts you can buy for a product that must sell for a price that customers can pay, and, as you've noted, those design decisions were likely made in 2006. And from where I sit, I've always viewed Wayne and Eric as marketing geniuses (in the best sense of that). 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 donovanf at starpower.net From bobdehaney at gmx.net Mon Mar 30 03:29:44 2020 From: bobdehaney at gmx.net (Bob DeHaney) Date: Mon, 30 Mar 2020 09:29:44 +0200 Subject: [Elecraft] K vs. KN Message-ID: <001501d60664$fc562a90$f5027fb0$@gmx.net> Perhaps some German slipped in?

Exactly the same in the maritime world. All ships should be using the same prowords all around the world - it makes it easier to deal with maydays and cross-language communication, non-native speakers learn the prowords with translation to their own language. It goes alongside standard message formats to know what to expect next when you?re writing things down. For example the word ?position? is followed by a lat and long. As I was told by our examiner for my civilian maritime licence: ?repeating is what happens after you eat too many pickled onions, on the radio we say again?

When I got finished, I noted that his passband centering control (left knob) was inoperative on CW. My immediate thought was that maybe the encoder was NG, but it worked fine for SSB. Someone else had a similar problem recently and he re initialized his radio. I asked my bro how long this problem had gone on and he said "Maybe a year or two?"? I checked the K3 UTIL files on my computer and I found an old file for his K3 dated 2016 so I downloaded it and the problem went away and I did not have to go and re enter everything. It was a quick fix and rather painless.? My brother said that he had not altered much from the factory settings anyway, but it was nice not having to check filter offsets etc. So all this work got me to dig out my Cady K3 book and read it as nightime reading before I fall asleep.? There are so many interesting things that you can do to your K3, that it makes my head swim in total confusion!? I am sure the K4 will be mind boggling! My 1939 Bendix RA-10 aircraft receiver has? Volume, Tuning, BFO, and Band change knobs. I seem to handle that OK. This past weekend, I used one of my own K3s in the WPX contest on 75 meter phone and made a few 100 watt QSOs during the daytime. ( I have made only a handful of 80/75M contacts)? I noticed that there was a terrible noise occupying about 15 kHz of the band, but it showed up on the P3 as occupying the entire 200 kHz passband. I checked PLL voltages using the DISP button and saw that the old style synthesizer was falling out of lock. I had to perform a synthesizer CAL. Then all was well again.? I was reminded that I had not upgraded the synthesizers in this radio! 73 Dave K1WHS From radioham at mchsi.com Mon Mar 30 12:11:30 2020 From: radioham at mchsi.com (David Christ) Date: Mon, 30 Mar 2020 11:11:30 -0500 Subject: [Elecraft] Not moving your wrist sending CW ?

For demanding operation (usually meaning working very weak signals) I use a stereo headset. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From rocketnj at gmail.com Mon Mar 30 12:41:44 2020 From: rocketnj at gmail.com (Dave) Date: Mon, 30 Mar 2020 12:41:44 -0400 Subject: [Elecraft] KPA1500 fans not working in auto mode In-Reply-To: <564686f4-6b0e-6f90-803c-d870007279c0@ca.rr.com> References: <564686f4-6b0e-6f90-803c-d870007279c0@ca.rr.com> Message-ID: I do not remember the exact values but the latest firmware changed the start & stop points for the different fan speeds. If it had gone to 50c without the fans turning on then I would definitely be concerned. Maybe someone from Elecraft can post the temperature crossover points for fans to increase or decrease speed. There is also a dwell feature where you can add delay before fans decrease in speed when cooling down. I?m happy with fan performance of current firmware.

My head still hurts:) I was not aware that you use "other" radios on SSB. John KK9A Frank W3LPL wrote: You would have to seriously compete in an SSB contest with some of the more modern radios in very crowded bands to fully appreciate how much better the more modern technologies are for both transmit and receive signal quality. The latest Flex radios are almost shockingly good, but all of the top-shelf modern radios are significantly better performers than the 12 year old K3 or even the K3S. We're discussing the most demanding situations affecting SSB transceiver performance: weak -- often distorted -- SSB signals surrounded by much stronger adjacent channel QRM. For much of the time on 20 and especially 40 meters the adjacent much stronger signals overlap well into the receiver bandwidth. Typical spacing between SSB signals is only 1.5 kHz, if you're lucky its 2.0 kHz and only rarely 2.5 kHz or more. This situation is rather unimportant for the casual contester, but its a game changer at the upper levels of serious SSB contest competition. I have not made technical measurements of K3 SSB transmitter and receiver performance nor do I have the capability to do so. I suspect the more modern designs have improved the dynamic response of their entire receiver and transmitter chain in ways that can't be captured by simple static performance measurements such as frequency response, dynamic range and IMD. 73 Frank W3LPL From gfitch at ku.edu Mon Mar 30 14:23:44 2020 From: gfitch at ku.edu (Fitch, Gordon) Date: Mon, 30 Mar 2020 18:23:44 +0000 Subject: [Elecraft] Elecraft Digest, Vol 191, Issue 30 In-Reply-To: References: Message-ID: <1585592623766.31757@ku.edu> Dave, what is stated as the cause of death on the CD ?

Message-ID: <754759523.3111001.1585546439995.JavaMail.root at starpower.net> Content-Type: text/plain; charset=utf-8 Hi Clay, This thread is a discussion about the relative performance of top-of-the-line modern transceivers in the most demanding situations faced by serious SSB contest competitors. The vast majority of transceiver users have no concerns about the performance of their transceiver under these conditions. We're discussing the most demanding situations affecting transceiver performance: weak -- often distorted -- SSB signals surrounded by much stronger adjacent channel QRM. For much of the time on 20 and especially 40 meters the adjacent much stronger signals overlap well into the receiver bandwidth. Typical spacing between SSB signals is only 1.5 kHz, if you're lucky its 2.0 kHz and only rarely 2.5 kHz or more. This situation is rather unimportant for the casual contester, but its a game changer at the upper levels of serious SSB contest competition. For transmitted SSB signals we're concerned about situations where our transmitted signal is relatively weak and surrounded by much stronger adjacent channel QRM. The adjacent signals usually overlap well into the transmitted signal bandwidth and the other operator's receiver has much lower performance that our top-of-the-line radio. 73 Frank W3LPL ----- Original Message ----- From: "Clay Autery" To: elecraft at mailman.qth.net Sent: Monday, March 30, 2020 5:20:31 AM Subject: Re: [Elecraft] The Big Three...

Also true in U.S. Army radiotelephone procedure, at least how we operated in the Signal Corps in the '70s and '80s when I was in. Never heard or was taught 'words twice'. One would realize (with experience) when key parts of the transmission should be said twice due to noise or other difficulty with the channel, usually because of being asked to 'say again' a few times. Asking for a retransmission: 'say again your last transmission' 'say again all after' 'say again all before' The response would be: 'I say again ...' There is also 'I spell', when the word(s) weren't being received correctly. This was published in 'Allied Communications Pub 125: Communications Instructions -- Radiotelephone Procedures' (ACP 125), so these procedures should be somewhat standardized across NATO forces. 73, Steve K6ZX ------------------------------ Message: 14 Date: Mon, 30 Mar 2020 02:22:17 -0400 (EDT) From: donovanf at starpower.net To: elecraft at mailman.qth.net Subject: Re: [Elecraft] The Big Three...

Its probably not a coincidence that all of the top-shelf modern radios have a leg up on the K3 in the most severe competitive contest environments Think about what less than 14 years of improvement brought to the market in the post-World War II environment and the vast performance differential between the offerings from Collins and every one of their competitors: - 75A-1 1947 - 75A-4 1956 - KWM-1 1957 - S-Line 1958 Its amazing that the amateur radio HF transceiver market continues to drive significant performance improvements after all these years, just as it did from the earliest days of HF radio. 73 Frank W3LPL ----- Original Message ----- From: "Jim Brown" To: elecraft at mailman.qth.net Sent: Monday, March 30, 2020 5:45:21 AM Subject: Re: [Elecraft] The Big Three...

All ships should be using the same prowords all around the world - it makes it easier to deal with maydays and cross-language communication, non-native speakers learn the prowords with translation to their own language. It goes alongside standard message formats to know what to expect next when you?re writing things down. For example the word ?position? is followed by a lat and long. As I was told by our examiner for my civilian maritime licence: ?repeating is what happens after you eat too many pickled onions, on the radio we say again?

Message-ID: <6daf2e75-9265-efe2-2d2d-e37bd927ea7e at metrocast.net> Content-Type: text/plain; charset=utf-8; format=flowed I just repaired an early K3 belonging to my brother.? When I got finished, I noted that his passband centering control (left knob) was inoperative on CW. My immediate thought was that maybe the encoder was NG, but it worked fine for SSB. Someone else had a similar problem recently and he re initialized his radio. I asked my bro how long this problem had gone on and he said "Maybe a year or two?"? I checked the K3 UTIL files on my computer and I found an old file for his K3 dated 2016 so I downloaded it and the problem went away and I did not have to go and re enter everything. It was a quick fix and rather painless.? My brother said that he had not altered much from the factory settings anyway, but it was nice not having to check filter offsets etc. So all this work got me to dig out my Cady K3 book and read it as nightime reading before I fall asleep.? There are so many interesting things that you can do to your K3, that it makes my head swim in total confusion!? I am sure the K4 will be mind boggling! My 1939 Bendix RA-10 aircraft receiver has? Volume, Tuning, BFO, and Band change knobs. I seem to handle that OK. This past weekend, I used one of my own K3s in the WPX contest on 75 meter phone and made a few 100 watt QSOs during the daytime. ( I have made only a handful of 80/75M contacts)? I noticed that there was a terrible noise occupying about 15 kHz of the band, but it showed up on the P3 as occupying the entire 200 kHz passband. I checked PLL voltages using the DISP button and saw that the old style synthesizer was falling out of lock. I had to perform a synthesizer CAL. Then all was well again.? I was reminded that I had not upgraded the synthesizers in this radio! 73 Dave K1WHS ------------------------------ _______________________________________________ Elecraft mailing list Post to: Elecraft at mailman.qth.net https://nam10.safelinks.protection.outlook.com/?url=http%3A%2F%2Fmailman.qth.net%2Fmailman%2Flistinfo%2Felecraft&data=02%7C01%7Cgfitch%40ku.edu%7C2e96f047a1d243d4b9fd08d7d4c2de00%7C3c176536afe643f5b96636feabbe3c1a%7C0%7C0%7C637211805733105779&sdata=4F8ictw90SEzKKvWa%2BMz4qymEZzqhvoPk69nGG736wE%3D&reserved=0 You must be a subscriber to post.

While disappointing and painful, it's certainly the right thing to do. At this point in time the Pacific NW DX Convention scheduled for August is still going on as planned. That said, stay tuned for further developments. I've received many requests for club Zoom meetings in the last few weeks, so I'm certain most clubs are properly "social distancing" themselves. Social distancing is vitally important in keeping the virus in check, especially when so many amateurs fit the most vulnerable demographic. Let's all hope that this virus pandemic blows over quickly and we can get our lives back to normal! Finally, there have been many questions brought to me by members as to the status of the ARRL Volunteer Examiner program, and also questions as to how the upcoming ARRL Field Day event will be affected. I'll deal more with these questions in my next update, as I have a teleconference with other members of the Board's Programs and Services committee scheduled later this week. The staff at ARRL HQ are adjusting to the "new normal" of working mostly from home, (as are we all), so please be patient when attempting to contact them regarding any issues. 73, and please stay safe!

I did wait on buying a K3S but I did so, only after learning of the improved SSB receive audio. As to transmit audio, I find there are several critical areas under the users control that do affect the SSB transmitted audio. I am not a fan of external EQ and Processing.? Lousy audio going in which is EQ'd and Processed sounds like lousy audio that is EQ'd and processed.? Otherwise stated, one can't make a silk purse out of a sows ear. Factors which affect audio are namely mike technique and room acoustics.? And to some noted extent the adjustment or setting of the K3S internal EQ.?? In order to determine mike technique one needs to be able to record and playback their transmitted audio. You can't do it with headphones and the monitor system.? Carefully listen to the recording. ? Adjust and repeat as needed. ? In this process one needs to move the mike, thus changing mike-to-mouth distance along with talking direct into the face of the mike.? The frequency response of most mikes will change as one moves off to the side of the mike.? Likewise, lip smacks, nasal noise, denture buzz, and others is affected by mike-to-mouth distance.? If it is a dynamic mike, closer to the mike will enhance the lower end. Back away and the low end goes down.?? You can use this to your advantage, understanding the artifacts of mike-to-mouth distance. If one has any fan noise, room reverberation or HVAC noise,? I suggest working closer to the mike and adjusting the MIC level and/or Speech Processor levels down.? Excessive processing brings up unwanted noises. ?? Of course changing or improving room acoustics is another advantage, if this can be done. {Topic for another discussion.} As recommended by Bob Heil, Jim Brown and others including me. FYI -? I'm using a dynamic professional grade Shure SM58 mike direct to the radio. ? The TX EQ is as follows: 50 Hz -16dB, 100 Hz -16dB, 200 Hz -16dB, 400 Hz, -12dB, 800 Hz -0dB, 1.6kHz -0dB, 2.4 kHz +3dB, 3.2 kHz +6dB.?? ESSB is OFF.? As others have indicated, and as I have determined, using the record and play back method described above, this sounds really good.?? And my voice is no Don Pardeau either!? I work directly on axis and about 1" from the face of the mike.?? With another mike brand/model,? I find that I must work 4" or about one fist distance from the face of the mike. There is no short coming of the K3S receive or transmit audio. It is excellent communications audio. 73 Bob, K4TAX On 3/30/2020 8:44 PM, Scott Manthe wrote: > When I was active, I often got unsolicited positive comments on my > audio quality.

During these times stations are basically on top of each other or very closely spaced. We tend to hear stations from many different areas simultaneously. Here in CA I was hearing JA, US, EU and South American stations at the same time on 20 meters. After working the strong stations it is the weaker ones that become very important. With the default settings things can get quite jumbled and the audio is not clean and crisp. I tend to ride the HI and LO cut bandpass knobs along with RF Gain during this time to get an advantage with blocking out stations as best I can. K3/K3S AGC also plays into this situation. N6TV has done quite a bit of work with AGC and has some interesting suggestions that improve the receive characteristics with many stations in the passband. The problem Bob found was that close-in stations would cause AGC action that would make the stations blend together. The best description is that you simply heard ?mush?. With the work that was done and improvements in firmware much of this has been improved, although I?m not sure that it can ever be completely eliminated. This is a trait common to most modern radios, although they tend to differ in the amount of mush and distortion that occur. The key is to know your radio and apply settings that improve its characteristics. Note that all radios have compromises that tend to only be heard in extreme conditions such as we see in contesting. All of this has been discussed on the reflector some time ago. In the Nabble archives look up ?K3 Receiver Mush?. As a contester, it is very important that we know and understand all aspects of our stations, including the radios to get peak performance. The best contesters get the most from their radios; they can only do that by knowing them. Contesters that are new to a big station may not know the details of the radio in front of them, which says more about the contester than the radio. I chose the K3 and K3S for my station because they were the best available. I still believe that, and use them in every contest I enter. Now my antennas could definitely use some improvement? 73!

Message-ID: <047b01d6077b$038a85b0$0a9f9110$@carolinaheli.com> I'm about to pull the trigger on a Hustler 6BTV (6-Band, 80, 40, 30, 20, 15, 10 meters). It will be temporarily installed (with radials) about 200' away from my house. I'd like to run CATV "hardline" but I'm not sure how to get a 2:1 UnUn with a wide enough bandwidth on the antenna side (the impedance with 60ish radials should be in the 35ohm range). In addition I believe I will be ok on the RIG side to just connect RG6 (75ohm) to the hardline and direct to the rig since my K3S can match the impedance.

I'm building a transceiver test bed and I'll regularly report the progress of my test setup, procedures and results. The intent of my test bed is to document the transmitter and receiver performance of modern transceivers in the intense QRM environment encountered by contesters. My test bed will not be used to duplicate technical tests such as sensitivity and dynamic range that are well documented by other expert testers. I welcome constructive comments about my test bed, test procedures and results. Hopefully other technically inclined hams will develop similar test beds so we can compare our test procedures and results. I will share my initial test results prior to availability of the Elecraft K4. Test Description: Transceivers #1 and #2 will be QRM generators using two K3 transceivers with DVRs and stored Morse messages feeding Array Solutions Powermaster digital wattmeters and individual dummy loads. The QRM generator transceivers will use various frequencies very close to the frequency of transceiver #3. The DVRs and CW message memories in the QRM generator transceivers will store various voice and Morse messages which will change as the test procedures evolve. The power levels and frequencies of the QRM generator transceivers will be varied in accordance with written test procedures. Transceivers #3 and #4 will be the transceivers under test. Transceiver #3 will be the transmitter-under-test feeding an Array Solutions Powermaster digital wattmeter and dummy load. Initially they will be my K3 and FTdx5000 transceivers and my Heil and ModMic microphones. Transmitter #3 will generate call signs and contest exchanges to be transcribed by operators listening to transceiver #4. The frequencies, power level, callsigns, contest exchanges, microphones and operator controllable settings (e.g., compression and equalization) used by transceiver #3 will be varied in accordance with written test procedures. Transceiver #4 will be the receiver-under-test connected to a dummy load. Initially they will be my K3 and FTdx5000 transceivers. The callsigns and contest exchanges transmitted by transceiver #3 will not be known to the operator transcribing the audio heard from transceiver #4. A variety of operators will be invited to transcribe the callsigns and contest exchanges they hear on this transceiver. 73 Frank W3LPL From ghyoungman at gmail.com Tue Mar 31 13:54:11 2020 From: ghyoungman at gmail.com (Grant Youngman) Date: Tue, 31 Mar 2020 13:54:11 -0400 Subject: [Elecraft] Special Bulletin- More Event Cancellations, ARRL Digital Editions off-line In-Reply-To: References: <20200331161208.3A5582058EC8@bmail.arrl.org> Message-ID: <37698F2C-1436-4E57-8128-BF82779F0F29@gmail.com> Seems to me we can pretty well assume that EVERYTHING is or will be cancelled for the forseeable future ?.

But the loss in 200' of RG/6 even at 1:1 is about 2.9 dB! That is almost half your power. RG/8 would have only 1.9 dB loss, and with a probable SWR of about 1.5:1 you would have a total loss of 2.2 dB. Even better would be Belden 9913 or similar coax, which would give you a total loss of 1.6 dB.

I wouldn't worry too much about the impedance mismatch if your radio has the tuner installed. Hook everything up with the CATV hard line, no Unun, and if the tuner makes the radio happy, declare victory. Especially if the installation is temporary, don't sweat 15M and above -- at the solar minimum, there's not a lot happening on these bands for a few years. Also, I suggest that you check the feedpoint Z with a good antenna analyzer right at the antenna. Depending on your soil conductivity, 35 ohms is pretty optimistic. 73, Jim K9YC On 3/31/2020 9:39 AM, AE4PB at carolinaheli.com wrote: > I'm about to pull the trigger on a Hustler 6BTV (6-Band, 80, 40, 30, 20, 15, > 10 meters).

Far be it from me to contradict a seasoned contester like W3LPL, nor to dismiss the comments of many others, but I wonder how many "the K3 sounds bad on SSB" comments occur because of operator error in setting the AGC and gain controls improperly? In my experience, a number of such declarations are due to not knowing how to set the controls to optimum. Then, at some point, these perceptions attain legend status. Now, if W3LPL's assertion is that the need to know *how* to set those controls properly poses a problem for contesters, that could be a valid point. If, for instance, the newest Flex 1,000,000 just works out of the box, with the default settings, that may appeal to contesters and I understand that.? However, it's never bothered me that the default AGC parameters of a K3 aren't optimum for me... that's why the controls are variable, no? I've learned to set them to obtain incredible SSB readability. My settings aren't magical; I got them from others and are based on my own measurements (which others have dismissed over the years, I don't know why).? Al? W6LX ? >>> With the default settings things can get quite jumbled and the audio is not clean and crisp.

I rely on the bandwidth of the filter that follows which is created by DSP. It works fine for me. I know this setup has stop bands that are around 105 db, but I don't know what the shape factor is; some of this is available from Bob Sherwood's site. The filters you are discussing are roofing filters. They are primarily there to protect the the ADC from seeing too much energy and overloading. Selectivity is secondary. Unless you perceive that you are having a problem, I wouldn't go to the trouble of swapping out filters. However, there are a number of hams who will disagree with me. 73, Barry K3NDM ------ Original Message ------ From: "Gary Hunt via Elecraft" To: elecraft at mailman.qth.net Sent: 3/31/2020 2:55:44 PM Subject: [Elecraft] Subject: K3 SSB filters >Subject: [Elecraft] K3 SSB filters >Message-ID: <6337fc8e-6d4b-5a8e-1e3c-c45e1ecde13f at pinewooddata.com> >Content-Type: text/plain; charset=utf-8; format=flowed > >With the recent experience in SSB? contests, I'm thinking of upgrading >my SSB filter(s).

One can't have good quality from a wide bandwidth if the adjacent station is splattering over into your receiver bandwidth. Something has got to give.?? After all, it is communications quality audio.?? Narrow the bandwidth to 1.8 kHz and adjust the SHIFT to better the quality and lessen the QRM. 73 Bob, K4TAX On 3/31/2020 1:55 PM, Gary Hunt via Elecraft wrote: > Subject: [Elecraft] K3 SSB filters > Message-ID: <6337fc8e-6d4b-5a8e-1e3c-c45e1ecde13f at pinewooddata.com> > Content-Type: text/plain; charset=utf-8; format=flowed > > With the recent experience in SSB? contests, I'm thinking of upgrading > my SSB filter(s).

I don't think you need a unun because the additional loss due to SWR running RG/6 at 2:1 is only 0.381 dB, and the unun itself would certainly have some loss. But the loss in 200' of RG/6 even at 1:1 is about 2.9 dB! That is almost half your power. RG/8 would have only 1.9 dB loss, and with a probable SWR of about 1.5:1 you would have a total loss of 2.2 dB. Even better would be Belden 9913 or similar coax, which would give you a total loss of 1.6 dB.

Far be it from me to contradict a seasoned contester like W3LPL, nor to dismiss the comments of many others, but I wonder how many "the K3 sounds bad on SSB" comments occur because of operator error in setting the AGC and gain controls improperly? In my experience, a number of such declarations are due to not knowing how to set the controls to optimum. Then, at some point, these perceptions attain legend status. > > Now, if W3LPL's assertion is that the need to know *how* to set those controls properly poses a problem for contesters, that could be a valid point.

Connect the 1/2" CATV 75 ohm hard line to the feed point on the antenna, and use a short jumper of RG8X or RG6 between the hard line to the radio for convenience. 73 Bob, K4TAX On 3/31/2020 1:06 PM, AE4PB at carolinaheli.com wrote: > The 200' run is Cable TV hardline (1/2") 75 Ohm, that's where the UnUn would go (maybe). > > Jerry Moore > Cell: 803-431-1870 > > -----Original Message----- > From: Victor Rosenthal 4X6GP > Sent: Tuesday, March 31, 2020 1:58 PM > To: elecraft at mailman.qth.net; AE4PB at carolinaheli.com > Subject: Re: [Elecraft] 75ohm Impedance question K3S and Antenna side. > > I don't think you need a unun because the additional loss due to SWR running RG/6 at 2:1 is only 0.381 dB, and the unun itself would certainly have some loss. > But the loss in 200' of RG/6 even at 1:1 is about 2.9 dB! That is almost half your power.

What the roofing filters will do is keep the receiver from reducing the hardware AGC for stations which are within the roofing filter passband. It takes adjacent signals in excess of S-9 +30 for the adjacent signal to activate the hardware AGC (which protects the front end DAC from overload). If the interfering station does not exceed that threshold, then the DSP filters will take care of it, and the need for more narrow roofing filters is superfluous. 73, Don W3FPR On 3/31/2020 8:57 PM, Bob McGraw K4TAX wrote: > Remember, different brands of 2.1 or 1.8 filters are not necessarily equal.

In this case the OP needs around 200 feet. Once your get the velocity factor for the 1/2" hardline... that is ballpark 80 to 83%. for 3.540 mhz is 265 feet x .8 = 212 feet. If you don't have a piece of test gear to get it cut correctly then put a 50 ohm dummy load at the far end keep cutting until your wattmeter says 1 to 1 swr. 1/2 wave multiples will hit most of the ham bands. A little high in the 30m band. Close enough. 73 John k9uwa John Goller, K9UWA & Jean Goller, N9PXF Antique Radio Restorations k9uwa at arrl.net Visit our Web Site at: http://www.JohnJeanAntiqueRadio.com 4836 Ranch Road Leo, IN 46765 USA 1-260-637-6426 From jim at audiosystemsgroup.com Tue Mar 31 23:52:34 2020 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 31 Mar 2020 20:52:34 -0700 Subject: [Elecraft] K3 SSB filters In-Reply-To: <81e0bbfc-49a0-9521-5211-7f778345456e@embarqmail.com> References: <20200331234831.ftc4ipaltm2hyg2h@n0nb.us> <81e0bbfc-49a0-9521-5211-7f778345456e@embarqmail.com> Message-ID: <16e87895-d5c0-4029-4dd2-1d0cbce2e3ab@audiosystemsgroup.com> On 3/31/2020 8:36 PM, Don Wilhelm wrote: > What the roofing filters will do is keep the receiver from reducing the > hardware AGC for stations which are within the roofing filter passband. In addition, when the DSP IF filters are set to about the same width as the roofing filters, the two filters "cascade" -- the rejection of adjacent signals is the sum of the rejection of the two filters. 73, Jim K9YC
