Message-ID: Just 6 weeks from now FDIM 2015 will open its doors for attendees to pick up their badges and goody bags. We need some time to finalize arrangements so, if you plan to attend FDIM, please register now ! Details are on the FDIM webpage - www.qrparci.org/fdim For those that don't know, FDIM (Four Days In May), is the annual conference of QRP ARCI (QRP Amateur Radio Club International). It all takes place in Fairborn, a nice area on the outskirts of Dayton OH, and it runs in parallel with the famous Dayton Hamvention. FDIM is open to everyone - not just QRP ARCI members. The event will appeal to anyone interested in home construction, antennas, portable operation, Arduino - it is definitely not just for QRPers ! We start with a day of seminars on Thursday 14 May and a Vendor Evening where traders can show and sell their QRP related merchandise (a table at vendor night is provided free of charge - let me know if you need one). On Friday 15 May we organise buses from our hotel to the Hamvention. Late afternoon we start the annual Buildathon (this year building 4 items of test gear) - it's a social activity with support for inexperienced constructors. It also includes a Pizza Party ! Friday evening is 'Club Night'. An opportunity for regional QRP clubs to promote themselves and recruit members. The evening includes various fun & games and our Homebrew Competition. On Saturday 16 May there are more buses to the Hamvention and the FDIM Grand Banquet with awards and prize giving. As ever there are plenty of door prizes (several $1000s worth). The raffle will be for an Elecraft KX3 with accessories worth $2000+. Those that register online for the seminar will get free entry to the Seminar draw. Last year we gave away four Ten-Tec transceivers ! Tickets are not available on the day - it's just for those who register online.

I am able to keep the radio as modern/improved/upgraded as I wish - by choosing which upgrades I wish to ad. Having a my K3 means no need to buy a new rig every couple of years - or more often. Then having to deal with the new rig's teething pains - which the factory, unlike Elecraft, may or may not address. The K-Line is the most complete and easiest to operate HF station I have had in my entire amateur radio career. Completing my K-Line is a Pigknob - allowing me to control the radio a little more conveniently. Life is good!

For those that use the K3 as their main home radio - this would allow you to have larger knobs, spaced further out, and have that big radio feel - while those of us that travel constantly with our K3's can continue with the smaller footprint, which for me works great even though I have huge hands. Doing so would require re-engineering front panel, but probably not much more than that? Since the front panel is just ribbon-cabled to the rest of the radio. Seems like a relatively small engineering feat for a big bang but maybe its only an incremental change in terms of moving the needle and maybe that's not where Elecraft wants to focus.

Ms Craft allegedly took advantage of Bambershoot by claiming to have down-conversion which he mistook for a syndrome of the same name. Bambershoot was happy with his purchase until his friends told him all the problems he should be having with his new radio. According to Police spokesman, Ken Wood, "The poor man was distraught and raving about roofing filters.What the heck are roofing filters?" The arrest report filed by fellow-ham, Officer Ike Com, listed Bambershoot's original complaint as "radio mushiness" but notes, "I told him all my radios sound mushy but he was upset he couldn't hear it on his.When we tried to calm him down he became unruly." Su Yae, an EMT called to the scene, defended Bambershoot saying, "When I got there they claimed he was making clicking noises with his keys but I never heard any key-clicking.The poor man was just frustrated because his purchase had so many faults he couldn't find.I feel sorry for him." Bambershoot is being held on $10,000 bond.Police are still searching for the elusive Ellie Craft. -- Buck k4ia From esteptony at gmail.com Wed Apr 1 15:32:05 2015 From: esteptony at gmail.com (Tony Estep) Date: Wed, 1 Apr 2015 14:32:05 -0500 Subject: [Elecraft] Is there a K4 on the horizon?

But at least for me, the current radio does everything I would want it to do. The only additional feature that would help me would be if it would put Bouvet on the air. It used to be that radios were judged on sensitivity and selectivity. Those measures topped out decades ago, and everyone started looking at dynamic range, and then close-in dynamic range. At this point, further improvements in that spec probably aren't going to be noticed in most practical situations. Maybe the next frontier is in noise reduction, I dunno. But really, when you talk about the next Elecraft transceiver, the K4 or whatever, you have to ask what it's gonna have that you haven't already got. And then after you come up with something (e.g. simultaneous two-band receive & panadaptor) you have to ask if it really justifies a new design, or it's just gilding the lily. 73, Tony KT0NY From valvetbone at gmail.com Wed Apr 1 15:42:03 2015 From: valvetbone at gmail.com (Art Hejduk) Date: Wed, 1 Apr 2015 15:42:03 -0400 Subject: [Elecraft] Ham enthusiast arrested In-Reply-To: <551C3C83.5010008@aol.com> References: <551C3C83.5010008@aol.com> Message-ID: I like it.

I think there will still be some front end analog processing. That said, QRP is in the DNA of this company. Consequently, their designs have always had low receiver current drain in mind. IMHO, this has compromised performance. I know that the "faithful" are gnashing their teeth at this but I said, IMHO. One need look no further than the use of an SA612 for the second mixer. In a backpacking radio this is a good choice. But it has no place in a high-performance desktop receiver. By my reading of the spec sheets (I'll confess limited knowledge of DSP device specs) the mixer is weaker than the DSP. Hence the conventional wisdom that the need for hardware AGC is to "protect" the DSP, when in fact, it's protecting the mixer. We now have SDRs that can digitize wide swaths of the HF spectrum with good overload performance yet the mixer/DSP in the K3 requires banks of pricy crystal filters to limit the exposure to hundreds of Hz. This also leads to endless questions on this reflector about what crystal filters are "best." The best one would be a low IMD design that just eliminated the image with a robust DSP doing the rest. Just thinkin' out loud. We'll see what Visalia brings. Wes N7WS On 4/1/2015 11:41 AM, Doug Person via Elecraft wrote: > I think any new Elecraft radio is going to be cutting-edge DSP.

There were a number of useful answers suggesting, among others, the Intel NUC and the HP Pavilion. The replies I had off-line suggested that others were interested in the same question. So here?s an update: I happened to see an announcement this morning of the forthcoming ?Chromebit? - a "computer on a stick? by Google. While the Chromebit will run Chrome rather than Windows, the article led to some other possibilities. One of them is the Hannaspree - under 11 cm long and just wider than a USB plug, weighing less than 40 grams - which runs Windows 8.1 with a Quadcore Intel CPU. Similarly, the Intel Compute Stick.

BTW, I worked on diagnostics for GM's first in-dash touchscreen controller for radio and HVAC. This was the GM30 body ('86 Riviera). It was abruptly withdrawn from sale. We were told the decision was made because the lack of tactile feedback and parallax viewing issues were considered too dangerous (driver was forced to lean over and LOOK AT the screen). This was all part of GM's first generation computer assisted diagnostic tool, CAMS (a hardened PC with touchscreen in roll-around cabinet with hundreds of diagnostic cables).

For odd splits, we have to use the KX3 itself. The utility allows only standard tx/rx splits to be entered.. 1. Enter the transmit freq into VFO A; 2. Tap the A/B switch; 3. Enter the receive freq into VFO A; 4. Tap the A/B switch; 5. Hold SPLIT to allow different tx and rx frequencies. When this is done properly, VFO B will show your tx frequency, and VFO shows your rx frequency. If you'd like to you can memorize the channel. I would. Set the PL frequency first if the repeater needs it. 73! matt W6NIA On Fri, 3 Apr 2015 01:12:11 +0000 (UTC), you wrote: >All, I am missing something or having a senior moment.?

I am also the proud new owner of an SPE Expert 1.3K-FA solid state amp, and I have a question for the group regarding interfacing the K3 to the amp. My current setup is using my Icom 756 Pro III with the SPE Expert 1.3K-FA. The recommended setup for Icom was to connect both the Relay and ALC cables between the rig and amp. This is because the software in the amp automatically reduces the power in the rig to the best output level for the amp (on the amp LOW=500W out= 3W drive, MID= 1000W out= 6W drive, HIGH = 1500W out = 9W drive). It works flawlessly. Actually, I could leave the power on the Pro III untouched, and the amp reduces the power accordingly. My question for the group is, is there a way to allow the K3's output to be controlled by the amp? I see the note on p27 about not using an amp to control the K3's output, but wonder if there is a safe way to do it. For instance, could the K3 be set to say 15W out on all bands via the menu, then allow the amp to control the output via ALC for optimum drive?

Is SPE shipping amplifiers that violate type acceptance or did you modify that amplifier? Any commercial amplifier sold in the US can have a maximum gain of 15 dB.

Letting the amp control a radio's drive level is pretty much worst-case. This just about guarantees clicky, distorted ALC response as well as poorly shaped CW keying. Instead, we recommend adjusting the K3's drive level per-band (see CONFIG:PWR SET) to just reach the desired power level at the amp's output. This way, little if any ALC is used. The per-band levels are stored at the K3 and recalled as you change bands. The K3 has its own very clean internal, slow ALC to compensate for minor gain variations. We also apply ALC and compression within the DSP, at the audio stages--again with intent to minimize splatter. All gain-controlled stages are pre-crystal filter, ensuring that any dynamics are entirely band-limited before they ever get to an output stage. This goes counter to instructions for some amps. They assume you are not capable of properly adjusting the drive to compensate for per-band variations, so they instruct you to crank it to the max at the rig. But the proof can be heard on the air. A K3 properly adjusted per-band will be exceptionally clean. 73, Wayne N6KR On Apr 2, 2015, at 7:34 PM, AB2E Darrell wrote: > Hello all, > I am the proud new owner of a new K3.

The requirement goes back to the 1970's and is designed to prevent amateur amplifiers from being used for unlicensed ("freeband") operation with 5 Watt CB exciters. The intent was to match the gain needed to reach the US legal output power with the drive available from the typical exciter power level. For the Expert amplifiers to show 22 dB gain, they must be shipping without the attenuator or the distributor is removing the attenuators - both of which violate the type acceptance. On a deeper level, to design an amplifier with that much gain is bad design - part of the excess gains should be used for negative feedback to reduce IMD and improve stability. 73, ...

Message-ID: Greetings to the group. I have been reading this month's QST article on the Flex-Radio series. It referred to a "pan" function in the audio output. The short story is this allows putting a DX station operating split in your left ear, and listening to the calling stations in your right ear. So just wondering out loud, short of having a second subreceiver in the K3 (which I do not have) - When operating Split, I know you can quickly switch between DX and calling stations by holding the "REV" button. The problem of course is you can only hear one or the other. Is it within reach of a simple software enhancement from our heroes at Elecraft to route these two audio signals to the left and right headphone channels from VFO A and B? (With a study of the schematic I suppose I could answer my own question, but figure a little brainstorming here in the group wouldn't hurt and might lead to something interesting...)

Note that it's the high end Flex only that is in the neighborhood of K3 performance, and there is a reason for that which decidedly costs money. No cheap advantage just because it is software based. In my case I don't want the dependence on an operating system that sees transceiver internal operations as a micro micro micro niche in its target user population. The K3 functioning can't be undercut by a Microsoft OS or driver upgrade. At very least any Elecraft changes to their K3 proprietary code are aimed at improving things for K3 owners. If you want the Flex side of this discussion you need to be on the Flex reflector. 73 and good luck on your choices, Guy K2AV On Friday, April 3, 2015, Bruce Chadbourne wrote: > Greetings to the group.

The problem of course is you can only hear one or the other. Is it within reach of a simple software enhancement from our heroes at Elecraft to route these two audio signals to the left and right headphone channels from VFO A and B?" Answer: This is possible using SDR software with an I/Q feed from the K3 IF. Check out the LP Pan unit and NaP3 SDR software. You will also need a suitable sound card with stereo inputs and outputs. This software creates two SDR receivers within the computer, which can then be fed to the computer's sound card for playback. You plug your headphones into the computer's sound card output. The better the sound card, the better this will work. The wider the bandwidth of the sound card, the greater the width of the spectrum you can display. The software is free. LP-PAN costs $250. The recommended ASUS USB sound card costs $65. http://www.telepostinc.com/P3_comp.html 73, Jim K9YC From lists at subich.com Fri Apr 3 15:28:43 2015 From: lists at subich.com (Joe Subich, W4TV) Date: Fri, 03 Apr 2015 15:28:43 -0400 Subject: [Elecraft] K3 Enhancement In-Reply-To: <551EE362.7090702@audiosystemsgroup.com> References: <551EE362.7090702@audiosystemsgroup.com> Message-ID: <551EE9EB.8080404@subich.com> > This is possible using SDR software with an I/Q feed from the K3 IF. > Check out the LP Pan unit and NaP3 SDR software. This is also possible with many stand alone SDR receivers like SDR-IQ, Elad, etc. Software like SpectraVue (SDR-IQ) or HDSDR (generic) can link the SDR receiver to the K3 IF frequency. Many of the stand alone SDR receivers will provide better performance, greater image rejection and wider bandwidth than possible with LP-Pan/NaP3. 73, ...

I don't miss my flex at all! And let me just tell you, you will not get K3 performance unless you buy a 6700 flex at almost double the cost of a k3 with sub Rx. I have been an avid flex user for 3 years but the K3 is far superior in a lot of ways. Listening fatigue, afx, filtering that is a brick wall, and quick tunability make the K3 a much better option for me. Don't get me started on operating system lockups. I am an IT consultant by profession with thousands and thousands of support hours under by belt, and even I have occasional problems. When my PC dies, or gets a reboot, my K3 is still going strong. That has tremendous value to me. One misfire in a major contest and you'll wish for the standalone K3. I know from experience! Joe PS. I think the Flex radios are awesome. I have nothing against them or their company and they have provided a tremendous resource for ham radio. I just think the K3 is a better value for the money.

This is also possible with many stand alone SDR receivers like SDR-IQ, Elad, etc. Software like SpectraVue (SDR-IQ) or HDSDR (generic) can link the SDR receiver to the K3 IF frequency. Many of the stand alone SDR receivers will provide better performance, greater image rejection and wider bandwidth than possible with LP-Pan/NaP3. 73, ...

Why is that, Joe? We now have devices capable of 22 or even 30 dB of clean amplification. Why should we not use it? Just because FCC does not allow it in the U.S.? I'm not bound to FCC rules and I'd rather prefer to drive such an amp with 1 or 3 watts from the KX3 to get 1 kW out than to cascade the transceiver with a driver amp and then a final amp. Of course I'm just bound to German law which does not contain any "stupid" (pardon me, but it is!) amplification limits, just the maximum allowed power. How we generate it is up to us radio amateurs overhere. That also means responsibility, of course. :-) Happy Easter!

How we generate it is up to us radio amateurs overhere. It's not "stupid" when you become aware of the history. At one time there were no amplification limits. The problem wasn't with the amateur community. The problem was with the renegade CB community that was using the available high-gain amplifiers improperly and in violation of US law and with the manufacturers who were catering to them. The problems that were created became an enforcement nightmare consuming too much of the available enforcement resources.

A part of the first question...Can PL encode, or, PL encode-decode be set up on individual FM channel memories? . I have a requirement to set up FM channel memories for Amateur "standard" 5KHz deviation, while setting other FM channel memories for 2.5 KHz "narrowband" deviation. Is this possible without having to re-program FM dev each time I move from a wideband to a narrowband channel memory? . Does the PL or CTCSS menu also include digital PL (DPL) transmit and receive access codes, and, non-standard CTCSS codes?

Why should we not use it? Many of the solid state devices that claim 22 dB or more of gain are *not* clean at maximum output. That 22 dB specification is based on saturated power output - often in *pulse* service. If the manufacturer actually bothers to provide full gain and IMD curves for the device you will quite often see the gain drops significantly at maximum drive and or maximum output power while the "sweet spot" for IMD is 2 to 3 dB *BELOW* rated (maximum) output for the devices in use. Using 3 dB of negative feedback, another 3 dB of fixed input padding and another 1 + 2 dB of switchable input attenuation to provide "ALC" in the event of overdrive uses the total gain of the devices in a much more intelligent way. The high degree of negative feedback and fixed input padding cause the exciter to see a very constant and resistive load permitting the exciter to operate at its cleanest. The negative feedback also greatly improves IMD generation/linearity in the devices and by keeping the devices typically below the 1 dB compression point further minimizes IMD. 100 W to 1500 W (US Legal limit) is only 11.7 dB ... 100 W to 2500 W (VE legal limit) is only 14.9 dB. The US type acceptance standard provides "overhead" in either case (if the amplifier is capable of 2500 W). I see no reason - unless one *wants* to generate the typical "dirty Italian" signal that one *needs* 22 or 30 dB of gain. Most QRP rigs are so dirty (worse in many cases than an IC-706) I would not want to see them driving a 1500 W amplifier in any case. 73, ...

The op indicated he purchased the amplifier from (one of) the US distributors for SPE and that others who had purchased amplifiers from SPE through their US distribution channels reported the same high gain. Those amplifiers are *not legal for sale in the USA* - they do not meet the terms of their type acceptance. The rules also state that *nobody* is permitted to modify amplifiers *commercially* (e.g., a distributor for SPE) so that they are not compliant with the type acceptance. An individual amateur may make or modify *for his own* *use*, at most, *one* of a given model amplifier in any year.

Yes, it's ham radio, and FCC Rules require that our rigs use the minimum bandwidth required for mode being transmitted. A dirty transmitter occupies a lot more spectrum than a clean one. That dirty transmitter is using bandwidth that other hams may want to use. In contests, and DX pileups, signals are wall to wall. A CW signal SHOULD occupy only about 600 Hz to be 50 dB down, but MANY rigs occupy 4-5 times that. Ah, you say, 50 dB down is a lot. I respond, not if the signal is 40 over S9 -- 50 dB down is still S7! When we use more bandwidth than the minimum required, we as OPERATORS are in violation of FCC Rules.

My K3 behaves differently today compared to earlier firmware some years ago. Current FW is MCU 05.14, FPF 01.19, DSP 02.83. In DATA A mode: (1) PITCH shows N/A, in contradiction to the user manual. Seems to be fixed at 1500 Hz. That's fine with me, as I can adjust the mark/space tones in my PACTOR modem accordingly. (2) SHIFT/WIDTH controls are showing a strange behaviour: Based on the green LEDs next to the 2 controls, only LO/HI CUT is available, SHIFT/WIDTH is not. When moving LO/HI cut, filter graphic and VFO B display are both indicating a LO/HI cut, but what effectively happens is a width variation. Verification is easy: Acoustically or on the P3 display. 73, Markus HB9BRJ -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-SHIFT-WIDTH-in-DATA-A-mode-tp7601016.html Sent from the Elecraft mailing list archive at Nabble.com.

I used the 15 pin Linear jack on the back of the FTDX-3000 to accomplish a few things. First of all, I used Yaesu pin 2 (TX GND) as the key line for the KPA500, rather than the Elecraft's separate phono cable. Secondly, I used Yaesu pins 4, 5, 6 and 7 to supply the band data to the amplifier rather than rely totally on the KPA500's auto-sense of the frequency. And, of course, pin 3 is the common ground for all of this. At least on the FTDX-3000, ignore the KPA500's instructions about Yaesu pin 8 (TX INH) - just leave it alone. Also, I used Yaesu pin 11 (TX REQ), and ground, out to a separate push-button switch. When pressed, this forces the FTDX-3000 into a CW carrier (regardless of current mode), and I've set the menu #178 to let it output only 10 watts. So in use, I put the KPA500 to operate, press my little push-button switch which puts 10 watts out to the KPA500, which then generates about 200 watts into my tuner, which I quickly adjust if necessary. Let go of my push-button switch, and I'm good to go with about 25-30 watts preset on the FTDX-3000 power.

A big thanks to these gents for sending me input and experience with different solutions. All the input has been very useful this weekend as I have searched around for a single time reference solution for my needs. (everyone is going to be different) I thought this might help others that want to go down this path if they have similar wants / needs. I decided to still go with a Trimble Thunderbolt Rev. E ~2004 manufacture. This isn't going to be the lowest cost solution, but it covers my needs for the following: 1. Provide a very stable 10mhz external reference for my K3... mainly for fun and I might send in some reports to the ARRL FMT etc.. so there goes $$$ for the external freq reference add on for the K3. 2. The main reason I started going down this path was to use the external frequency reference input on the QS1R I run for the NC7J CW Skimmer. NK4I saved me a bunch of time (no pun intended) and pointed out the fact that the direct output on the Trimble TBolt won't work with the QS1R. Pete pointed me to Graham VK3XDK and David VK3HZ's XRef which will provide a 125 MHz reference for the QS1R from the TBolt 10 MHz output http://www.vk3hz.net/XRef/XRef_Home.html#XRef-Vx I exchanged email with David and have a XRef-Vx on the way... some more $$$ for the XRef-Vx shipped. Seriously not bad at all considering it has a TCXO on board that will take over if the Trimble output lock is lost. 3. Use a PPS reference to drive an NTP Stratum 1 server from my house. I get this out of the TBolt and also from most of the other solutions provided, but the TBolt has some other really nice monitoring capabilities. So for the NTP server, I ordered the latest Raspberry PI $50 with a case shipped and I searched high and low for other implementations using a TBolt with Linux / Raspberry PI for a GPS disciplined NTP PSS reference. Google 'time nuts' which I'm sure many on this list are familiar with... and I quickly found KO4BB's Thunderbolt Monitor Kit: http://www.ko4bb.com/Timing/GPSMonitor/kit.php Which will be a nice display for the serial output on the TBolt as it drives the NTP server (and QS1R and K3 when I'm operating) ARound $80 for this kit when Didier gets the next batch ready. This monitor kit also includes a PPS stretcher to increase the 10uS PPS pulse output by the TBolt to ~1mS. So that is my reasoning to stick with a TBolt... they seem to be holding their value if not getting more expensive and there is all the nice work and comparisons that have been done by KE5FX http://www.ke5fx.com/gpscomp.htm along with his Lady Heather software. It's pretty clear that the TBolt can still hold it's own. At the end of the day, do I need all this precision? Not really, but it's obsessive and fun! I get to spend more $$$ and have stuff shipped to me from around the globe and play with ntpd and cool software... provide a better service to the CW Skimmer community and precision time community with the NTP server. Plus I'll give the ARRL FMT a try and have some more fun. Thanks again for all the input off the list by the guys above. Max NG7M On Wed, Apr 1, 2015 at 8:27 AM, M.

I noticed today some electrostatics from my antenna (high voltage from antenna cable). (My K3 was not grounded properly - my fault). After that my K3 started transmitting all the time. There is no key paddle connected? The only way to stop transmitting is to turn on K3 with touched paddle (KEY ERR). Has anyone had a similar issue? I will be grateful for your help!

I should have included more details from personal emails I received from Dave, G3TJP. Bob W7AVK also mentioned the BG7TBL GPS Disciplined Clock and I totally got my wires crossed and didn't mention G3TJP in my write-up. Sigh.... Apologies to Mr. Lankshear... Dave took some time in a personal email to point out the follow about the BG7TBL which is going for ~144.00 on ebay... it really is a nice package... here are some of Dave's comments (in hindsight, I wonder if this would have been the way to go): G3TJP: "It?s a very neat and small unit, very professionally produced and comes complete with power supply and GPS antenna. I bought one and then a second one as a gift to a good friend. It uses the Morion double oven 10MHz xtal oscillator, or equivalent. The output is a decent sine wave with just enough distortion to give good harmonics at 10MHz intervals up to at least 50MHz, which is as far as I?ve checked. The Morion is actually a 5MHz oscillator that?s doubled to 10MHz, so you have a usable, locked signal at 5MHz also." Dave also mentioned that the seller 'fly-xy' is a decent guy and will ben over backwards to help you as you treat him fairly. i.e. if something needs to be returned or corrected. Plus, this unit is a turnkey package and he also sells a 10mhz distribution amplifier that looks interesting... another BG7TBL design. KE5FX has also reviewed Bob W7AVK's BG7TBL and has a nice comparison write up on his website (KE5FX of Lady Heather fame). The comparison is easy to find on KE5FX's site. Again, thanks to everyone that had input... I tried to mention everyone that pointed me in the right direction off the list and leaving out Dave G3TJP was my mistake.

Next, check the firmware version and upgrade that using the same utility. Read the manual and have a play with the functions to see what they do. Later on, you may want to do things like per-band I/Q nulling and temperature compensatin calibration procedures, but those can wait until you've had a chance to become more familiar with the radio.

Download the latest KX3 Utility and then update to the latest firmware and operate. Then at a more leisurely pace, go to the Elecraft website and review the KX3 hardware updates available - you do not have to do any of them unless you want to do it or have a particular problem associated with those upgrades. Also review the KX3 Application Notes and do any of those that you would like. There is one that you should check on before installing batteries, and that is the one dealing with the battery holder mounting screws - you may or may not have the problem mentioned. You might also want to apply some epoxy glue around the input power jack, especially if you are not using the right angle power plug. The power jack on very early KX3s were not glued and the power jack could break away from the board causing intermittent power problems. I did have that problem with mine. I have the first KX3 that came off the production line and have not yet found the need to do any of the hardware upgrades, but I have done some of the procedures in the application note, not because it was needed, but I wanted to 'walk' through the procedure for the experience. 73, Don W3FPR On 4/6/2015 1:06 AM, WA7YET wrote: > I purchased a KX3 when they were first introduced.

I actually was just looking for a 10 MHz distribution amplifier and found that he was selling the GPSDO along with matching Distribution amp for a very good price. There were options of a square wave output version or a sine wave output (which is what I purchased). The 8 output Distribution amp also contains a Morion 10 MHz double oven oscillator as well, which takes over if the input signal from the GPSDO is disconnected. I was not aware the Morion oscillator was doubling the frequency to reach 10 MHz, I have not found any documentation that mentions that anywhere else. The device is marked as 10 MHz. The included 12 V power supplies work fine, however they are wall warts with I think American 2 pin plugs, which need adapters to fit UK mains sockets. You need a fair amount of current for the ovens when they are heating up, so cannot just substitute a 1 amp supply. I opened up both units and the construction is very well done. No schematic or block diagram was supplied, though you can read what some of the chips are, in particular the GPS receiver is an NEO-6M. They may not satisfy the Time Nuts in every way, but they are good enough for for my uses as a stable 10 MHz for locking other oscillators. There is also a serial port (at true RS-232 levels so beware if you try to connect it to something like an Arduino unless you build a level shifter). It outputs the usual GPS NMEA sentences. I do have a another time and frequency standard which is an old HP Z3801A, it is probably better, but for my uses I would not be able to tell the difference. The HP is much larger, requires a 50 Volt supply so not nearly as portable. It also cost a lot more when I bought it on eBay quite a few years ago. 73 David Anderson GM4JJJ > On 6 Apr 2015, at 00:44, M. George wrote: > > A follow up to my write up...

For example, you can run 1440x900 on a monitor that is capable of displaying 1920x1080 or greater. Higher resolutions on the P3/SVGA will show more detail (more pixels per span) but require slower update rates (more FFT points). For example I am using a monitor capable of much higher resolution, but operate the P3/SVGA at 1280x1024 or 1440x900 as these give plenty of detail with higher update rates. -Paul -- Paul Saffren - N6HZ Project Manager Elecraft Inc. 831-763-4211 x122 www.elecraft.com From tscm4u at gmail.com Mon Apr 6 12:37:12 2015 From: tscm4u at gmail.com (J) Date: Mon, 6 Apr 2015 09:37:12 -0700 Subject: [Elecraft] 2-30 MHz Transmit?

There is no way to "open it up" further. The K3 blocks transmit (and receive) in the region of the 1st IF at 8.215 kHz - I forget how wide the guard band really is. The CB band at 25MHz is also blocked. If you must operate well outside the ham bands, you may want to install the KBPF3 option because the stock bandpass filters are peaked in the ham bands and receive will fall off as you move further away from the ham band edges. The KX3 can be opened for transmit (except for the CB band) most anywhere in the RF spectrum. If you have a valid need to transmit outside the ham bands (MARS licensee or other), contact K3support to obtain the instructions. I do not know about the unlocked VHF spectrum. 73, Don W3FPR On 4/6/2015 12:37 PM, J wrote: > Can someone furnish the exact "unlocked" or MARS transmit frequency > specifications for the K2, KX3 and K3? > > > > I think some of these radios may have gaps - due to RF filtering, IF, etc. > > > > Also, what about the unlocked transmit specs for VHF in these radios? > > > From mzilmer at roadrunner.com Mon Apr 6 13:04:42 2015 From: mzilmer at roadrunner.com (Matt Zilmer) Date: Mon, 06 Apr 2015 10:04:42 -0700 Subject: [Elecraft] 2-30 MHz Transmit?

The KX3 is used as a MARS ECOM / mobile unit with the KXPA100 amp. The K3 has a TX donut hole around the 8.2 MHz IF. I think TX is locked out from 7.5 to 9.0 MHz (if memory serves). The KX3 has no such restriction, being a Zero IF transceiver. Elecraft customer support can assist you with the unlock programs needed. You may have to supply your MARS credentials, but I'm not sure how that is handled today. It's been a while since I unlocked my radios here. Except for the K3's IF range, I've found no problems with TX and RX from around 2.8 MHz to 25 MHz. KBPF3 use is recommended though, so that you have enough gain between ham bands. Otherwise, the sensitivity falls off in between bands. Note: There is very little MARS / SHARES activity above 20 MHz. I'm also using the KX3's 2m module to work an above-and-below MARS VHF repeater split, plus the odd set of simplex frequencies NMCM has around 2m. Again, from memory, Elecraft specifies performance inside the ham bands. I don't believe there are any published specs for general coverage.

It's always a good idea to study the manual that comes with any new product. In addition to the one "in the box," Elecraft updates the manual every year or two and puts the newest version on the website as a pdf. 73, Jim K9YC From w7ox at socal.rr.com Mon Apr 6 15:03:41 2015 From: w7ox at socal.rr.com (Phil Wheeler) Date: Mon, 06 Apr 2015 12:03:41 -0700 Subject: [Elecraft] What do I do now?

Another thing you might want to do is call Elecraft tech support on the phone and ask them. They'll know your KX3 serial number and what you have in it, so are in the best position to advise you about any hardware updates, or add in boards you may want add. Plus, if you've not done so, download the KX3 utility and update your firmware to the latest released version. Then, too, consider adding the PX3 to your KX3. With Fixed-Tune mode firmware nearing release, it's particularly valuable; the PX3 really enhances my use of the KX3. 73, Phil W7OX On 4/6/15 11:25 AM, Bill Frantz wrote: > In addition to the advice from everyone else, > consider Fred Cady's book E740241 or E740242 - > "The Elecraft KX3" > . > > > 73 Bill AE6JV > > On 4/5/15 at 10:06 PM, mikeddy at gmail.com > (WA7YET) wrote: > >> I purchased a KX3 when they were first >> introduced.

In-Reply-To: <5523105C.1000800@roadrunner.com> References: <5523105C.1000800@roadrunner.com> Message-ID: Hi Roger, The noise floor is coming up because the RX circuitry was optimized for use from 250 kHz and up. Multiple sources start contributing significant noise below 250 kHz. Even though the new synth tunes down to 100 kHz, we tried to make it clear in the KSYN3A FAQ that the receiver isn't very sensitive in this range. It does very well in the 600-meter band (472 kHz), and has reasonable sensitivity in the 300-450 kHz range where there are many LF beacons. To quote from the KSYN3A FAQ: > Q: What is the K3's 100-490 kHz receive sensitivity? > > A: With preamp OFF, we measured about -125 dBm at 475 kHz.... At 250 kHz the sensitivity is about 10-20 dB lower, and it will go down from there. Yours is better than our baseline measurement. The FAQ entry continues: > We have not measured MDS below 250 kHz, but the receiver will gradually become less sensitive as you go lower in frequency due to band-pass filter roll off (in the KBPF3, which is required for operation below 160 meters). These tests were made with the signal routed through the RX ANT IN or XVTR IN jacks on the KXV3 option module. It would be possible to redesign the KBPF3's lowest-frequency filter to improve sensitivity below 250 kHz. However, the receiver uses PIN diodes extensively, and the rolloff from this band-pass filter helps prevent intermod in the diodes. I can see that we should clarify this topic further in the FAQ and installation manual. 73, Wayne N6KR On Apr 6, 2015, at 4:01 PM, Roger D Johnson wrote: > My new boards arrived today.

Since KSYN3A buyers may not always see the FAQ, we'll be adding something like this to page 1 of the KSYN3A installation manual: * * * Note on K3 low-frequency (100-400 kHz) receive coverage with the KSYN3A installed: With a KSYN3A installed, the K3 VFO can be tuned as low as 100 kHz. Sensitivity will be very good in the 600-meter band (470 kHz) if a KBPF3 filter module is installed, and the antenna is connected to either the RX ANT IN or XVTR IN jack on the KXV3 module. However, below 300 kHz, sensitivity starts to decrease quickly, because the K3's receiver was optimized for use on higher bands. Typical sensitivity at 300 kHz will be about -100 dBm. The preamp should be turned off at very low frequencies because it is not useful here; it will only increase noise level. * * * Let me know if you think further clarification would also be helpful.

I am using a Morion OCXO as 10-MHz reference for my K3EXREF and for my synthesized A32 PLL in my DEMI 1296 transverter. I got reports of 120-Hz sidebands on my signal (-10dBc) turned out to be due to excessive AC ripple riding on the 12v coming from my wall wart supply that I was using to power the OCXO. Using a scope I measured half a volt ripple on the 12v dc output. Substituting a clean 12v PS eliminated the sidebands. So be careful if you use a wall wart (many rectify with no dc filtering). I had a 17AH battery being charged by the wall wart which I assumed would present some filtering if 12v ran thru the battery to the OCXO. I could have added a large value electrolytic cap to do the filtering but I changed dc source to a well filtered Astron PS. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From jim at audiosystemsgroup.com Tue Apr 7 04:31:38 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 07 Apr 2015 01:31:38 -0700 Subject: [Elecraft] WTB Trimble ThunderBolt for K3EXREF / QS1R In-Reply-To: <201504070731.t377VtGk062316@ingra.acsalaska.net> References: <201504070731.t377VtGk062316@ingra.acsalaska.net> Message-ID: <552395EA.7030507@audiosystemsgroup.com> On Tue,4/7/2015 12:31 AM, Edward R Cole wrote: > A caveat regarding the use of simple "wall wart" 12v PS for supplying > a OCXO. Wall warts, especially those with switching power supplies, are ALWAYS a BAD thing, thanks to the RFI they generate. A GOOD thing -- a LINEAR supply, wall wart or otherwise, float-charging a battery, where the battery voltage is what the equipment needs, and the current from the wall wart is about 30% more than what it takes to run the equipment. No hum, no buzz, no RFI, and you've got a UPS in the form of that battery. ALL of the stuff in my home (with the exception of a TV and associated A/V gear) runs on that kind of charger-battery system. The only noise I hear is from my neighbors. 73, Jim K9YC From dg5bka at web.de Tue Apr 7 04:53:26 2015 From: dg5bka at web.de (web.de) Date: Tue, 7 Apr 2015 10:53:26 +0200 Subject: [Elecraft] 2-30 MHz Transmit?

Look at the status information before and after connecting and that may suggest a cure. The radio status will show "OFF" even when you are connected with the K3/0, at least it does on my setup. See especially in "radio settings" the "program mode" which should probably be "14 Elecraft Twin" in your setup.

MARS has stood for *all three* of the above proposed phrases since its creation after WWII for the Army and (later) Air Force as a formal organization of military and amateur stations operating on military frequencies to handle written and phone patch traffic for military servicemen. Because an amateur license was used only as an individual's technical qualification for membership while MARS conducted none of its business on amateur frequencies, AMATEUR was changed to AFFILIATE shortly thereafter. The Navy/Marine Corps finally created its own MARS in the early 1960s. Throughout the first 25 years of MARS's existence the primary task was to serve the serviceman as one of the limited means he had to communicate rapidly with his family. That mission was last carried out to any great extent during the Vietnam war. MARS has had to create an Emergency Communications mission to justify its existence since. About a decade ago, for reasons best understood by builders of bureaucracies, AFFILIATE was changed to AUXILIARY. MARS HF gear as yet does not need to meet NTIA specs. Once "CAP" was often cited along with MARS...the Civil Air Patrol operates HF/VHF nets similar to MARS, on Air Force frequencies. But about a decade ago CAP required communications equipment to meet NTIA specs...something no ham gear is going to meet. With respect to the issue of a manufacturer artficially limiting the transmit frequency coverage of its equipment to ham bands only, I find such an attitude paternalistic and condescending. It plainly conveys the attitude that the customer is too stupid to avoid improper or illegal operation of the equipment. There should be a menu item that allows either full or ham-band-only coverage. That is all. I have over several decades found full band transmit coverage to be routinely useful for test signal generation in addition to MARS work.

Message-ID: Anyone know how far along Elecraft is in shipping the new synthesizers for the K3? The only reason I ask is because I ordered a 3rd for our club radio which I have been holding since the end of February (ordered on the 27th). I wanted to get it installed so that one of our members can write a "Go Back" program to reset our K3s to where we had them set before Field Day started. That way if a new op sits down after the previous op adjusted things to their liking, the new op could reset everything back to the starting point. Since I felt there might be some changes with the new synth. I figured I would wait to hand off the rig after the board is installed.

So step 1 is to pull the power cord out of your router and see if the problem goes away. If it does buy a different router. Step 2 is to remove your antenna cable and make sure the birdie does not decrease in strength. If it does then it's probably a signal coming in on your antenna and not something generated inside the K3. After confirming that it is internally generated, step 3 is to remove the K3 top cover and listen to the birdie while you move the various coax cables inside the K3 around. If you find a position that eliminates the noise, tape the cable in place with some painters tape. 73, Mike K2MK k1tl wrote > Hi all, > > I have been having a problem with a 6m internal birdie around 50.096 which > is fairly strong and interferes with any signal(s) around that frequency. > I > did the "birdie removal tool" thingee but seems to put a small "void" in > that area when I did it. > > Have any of you K3 owners have a similar problem? > > I'm wondering if it may be a cabling issue with the SYNTH boards cable > routing.

I did the "birdie removal tool" thingee but seems to put a small "void" in that area when I did it. Hi Tom, The SIG RMV method can, in some cases, introduce a small dip in audio response at that specific frequency. The way the K3 owner's manual describes it is: "You may hear a slight tuning artifact as you tune in and out of the affected VFO segment." (See CONFIG:SIG RMV description.) This is an unavoidable side effect of how SIG RMV works. SIG RMV allows you to apply a small shift to both the first and second local oscillators, which can shift the birdie completely out of the passband while shifting the crystal filter passband only a small amount (and keeping the VFO accurate). But if the target signal happens to be close to the edge of the crystal filter passband, even a small shift could attenuate that point in the tuning range by a few dB. Generally, this is preferable to hearing the birdie. How successful SIG RMV is depends entirely on whether the birdie results from the first LO's fundamental, or from a harmonic. If it's due to a harmonic, which is usually the case, SIG RVM can be very effective. For example, shifting the LO 100 Hz would shift the birdie 1000 Hz in the case of a product involving the 10th harmonic of the LO. If the birdie you're removing is due to the fundamental of the LO, you may be forced to move it farther, creating a greater chance of an audible tuning artifact. Unfortunately there's no way to completely eliminate birdies in a high-dynamic-range superhet receiver. When we designed the new synth, we spent a lot of time tuning through the ham bands, slowly, at multiple bandwidths. We selected divider values (etc.) for the new synth such that ham-band birdies were "virtually" (but not entirely) eliminated. 6 meters is especially difficult because both the target band and its image band are both 4 MHz wide. Nonetheless, I think we did a pretty good job of minimizing birdies here. There are other things you can do about birdies if a small residual artifact is an issue. In CW mode you might try using CW reverse instead of CW normal. Or you can use a different crystal filter with a different offset. In SSB mode you can turn on the notch filter. But before taking any of these more drastic steps, I would also check the orientation of the coax cables associated with the synthesizer(s). Sometimes just moving a cable a bit can greatly attenuate one problematic birdie. Let me know if you have any further questions about this. 73, Wayne N6KR From tscm4u at gmail.com Wed Apr 8 14:13:23 2015 From: tscm4u at gmail.com (J) Date: Wed, 8 Apr 2015 11:13:23 -0700 Subject: [Elecraft] 2-30 MHz TX Resolved - Thanks Message-ID: <001201d07227$b4bb5010$1e31f030$@gmail.com> Matt, Don and others who responded to my questions regarding TX outside of the hambands (for valid radio services). thanks for the technical advice and assistance.

Message-ID: <0NMI000T6OZP8330@VL-VM-MR006.ip.videotron.ca> Hi You could buy a 3s battery such as what is used in radio control planes and quadcopters. . There are various current ratings available. You can choose one that fits the inside of the radio. As to a charger I've used a turnigy accucel 5 amp. Works very well but you need an external 12v power supply rated at 5 amp or more. It is made for lipos and other battery types and will do per cell balance. It has safety features and you can add a temperature probe for further safety. In any case,? you should not charge it in the radio but outside in a fireproof container. Never leave one unattended. The turnigy is about 35$ from hobbyking.

Some contact materials need to switch more current than others in order to stay healthy.

If the PTT switch closes before the PTT button travel is complete, you will hear a 'pop' as the PTT button contacts the microphone case. In other words, I do not think the switch itself is the problem. If you examine the Shure PA mic specs that was mentioned, you will find that the microphone element is normally open - in other words, you have to depress the PTT button to activate the microphone element. Depending on the relative contact times of the PTT switch and the mic circuit (both on the same switch), if the mic element switch is activated after the PTT is closed, no 'PTT noise' will be present. Many ham mics are wired so the mic element is always 'closed' which allows the microphone to be used for VOX without pressing the PTT switch. That arrangement can cause noise as the PTT switch is depressed since the PTT button parts are still rubbing on the mic housing after the PTT switch has closed. 73, Don W3FPR On 4/9/2015 10:39 AM, bill wrote: > SHURE 514B > > http://cdn.shure.com/user_guide/upload/423/us_pro_514b_ug.pdf0.pdf > > the switch will outlast anyone .... human or otherwise, > > the ptt assembly is not noisy .. > my kewood mobile hand mic squeaks as the button is pressed,$@!%$^* > From km4ik.ian at gmail.com Thu Apr 9 13:41:59 2015 From: km4ik.ian at gmail.com (Ian - Ham) Date: Thu, 9 Apr 2015 13:41:59 -0400 Subject: [Elecraft] Slightly OT: Georgia QSO Party in 48 hours!

The Georgia QSO Party is routinely hailed as one of the country's best QSO parties! This is the one time a year when all (or nearly all) 159 counties in Georgia will be activated. If you are a county-hunter, looking for band or mode fills for your WAS/Triple Play, or just like to contest and have fun, please come join us. Activity will be hot and heavy on all HF bands, using SSB or CW. The rovers are all ready to head out and activate those rare counties so you county-hunters can up your counts and/or get your band/mode fills. The fun starts at 18:00 UTC this Saturday, April 11. The contest runs for 10 full hours on Saturday (1800 UTC - 0400 UTC Sunday) and ten full hours Sunday (1400 UTC - 2359 UTC). I'll be active the entire contest on the phone portions of the bands. If you need Georgia, or Fulton County, give me a shout and we'll get you taken care of. For more details, please see http://www.georgiaqsoparty.com. See you on the air this weekend! 73 de, --Ian Ian Kahn, KM4IK Roswell, GA EM74ua km4ik.ian at gmail.com Please join me in the Georgia QSO Party April 11-12, 2015.

I was transferred to Howard who asked me to tap DISP and scroll through the menu items. When I did I found two new displays: SYN 1 OK and SYN 2 OK. This verified my new synthesizer boards were plugged in correctly and the TMP cables were installed correctly. Thanks Howard. I do not know if SYN 1 OK appears if only one KSYN3A board is installed (KRX3 not installed).

At one end of rotation of R2 (the bandwidth pot) you should have near 6 volts on the cathodes of D5 and D6, and at the other end of rotation you should have near zero volts. You can measure with your DMM. I suspect you have zero volts all the time. 73, Don W3FPR On 4/9/2015 2:43 PM, Kenneth Talbott wrote: > Even in the extreme counterclockwise position of the Filter pot, the width > is TOO wide.

Windoze mixer, select the sound card you're using, make sure it's panned to the center. I don't have Win 8.1, but I do have Win 7. It's not easy to bind Balance. Here's how in works in Win7. First, click on the Speaker icon on the task bar. Then click on Mixer. Then click on the icon in the top left corner for the sound card you're using. You should see Speaker Properties. Click on the Levels tab. The Balance tab is on the right in that window. Also, check Windows output level (not turned below about half), plug headphones into the output, transmit with MMTTY. You should hear the RTTY tones. Check that MMTTY and the K3 are set for the same RTTY tones and baud rate. Default is 2125 Hz, 45 Baud. Check that you are NOT using a serial port for PTT (in MMTTY). Check the VOX Gain. Check the Line In Gain -- in digital modes, the Mic Gain knob becomes the Line In Gain. Make sure that you are in VOX mode on the K3. The "right" level for cleanest signal should give 4-5 bars of ALC. Make sure that you are in AFSK mode on the K3. > Oh yeah, Win 8.1 > > > And next comes FLDigi? For that, set the K3 for DATA A. > Must I get yet another gadget to put between the computer and the K3? No, just a cable wired correctly. See the manual. BUT -- a better sound card can improve weak signal decoding a LOT, especially for other digital modes like JT65 (and probably PSK31). See http://k9yc.com/USB_Interfaces.pdf I wrote this a year ago and did the research a few years before that. The specific sound cards I talked about are all discontinued, but are available on EBay. If I were doing it today, I would look at the ASUS Xonar U5, which N8LP recommends for use with his NaP3 software. This piece also includes a tutorial on setting levels. For a better decoder, check out 2Tone, which WinWarbler integrates nicely with MMTTY. Serious RTTY contesters are using multiple RX windows, one running MMTTY, one or more others running 2Tone with different decoding algorithms. RTTY is prone to errors from noise,fading, and QRM, so having decoders with different algorithms gives a better chance of getting calls and exchanges right the first time with no need for a repeat. 73, Jim K9YC From lists at subich.com Thu Apr 9 18:21:43 2015 From: lists at subich.com (Joe Subich, W4TV) Date: Thu, 09 Apr 2015 18:21:43 -0400 Subject: [Elecraft] K3 How to get MMTTY to work with K3 In-Reply-To: <5526F40F.7020204@audiosystemsgroup.com> References: <5526F40F.7020204@audiosystemsgroup.com> Message-ID: <5526FB77.9070706@subich.com> > It's not easy to bind Balance.

Select the Playback tab ... double click on the output device ... in the properties dialog, select the Levels tab then click on the "balance" button.

It is more important to set the K3 MENU:MIC SEL to Line IN while in data mode (AFSK A or DATA A) so the Line Input is active for data modes! Once you've done that the "mic gain" control on the front panel controls the modulation level (set for 4 bars of ALC) and turn on VOX unless you have configured MMTTY/FLDIGI to control PTT using radio commands. 73, ...

One note: Be sure MENU:MIC SEL is set to LINE IN and LINE+MIC to OFF. LINE+MIC ON will leave your microphone hot with room noises, dogs barking, and the like. You can ask me how I know this but you can probably figure it out without my help. :-) The 4 bars ALC [5th maybe flickering occasionally] can be set while in TX TEST, so you're not making any RF. Then go into TX NOR and set the power you want with the PWR control. Unlike our fathers' radios [I guess that would be mine at this age], you *cannot* control power output with the MIC/LINE IN gain. For RTTY with MMTTY, I use AFSK A. It is LSB, and having the pitch of the signals go up as I tune up in frequency makes more sense to me than DATA A which is USB. I can't hear 2125 Hz at all so I set the K3 PITCH to 915 [as low as it goes]. Be sure to set MMTTY to 915 also. The lower pitch will also reduce the "RTTY Headache" from the higher pitch. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 4/9/2015 3:21 PM, Joe Subich, W4TV wrote: > >> It's not easy to bind Balance.

In fairness, the 180S-1 was not a common component of Collins ham stations, but it's still around $13K without it. I acquired an S-3 line in the mid-60's. The only way I did it was because I was single, getting combat pay and per diem because we were TDY all the time, and I didn't have any other use for the money. Didn't see the radio until I came home. Good that I did it then ... married my wife when I came home, made a couple of kids, adopted a couple more, and that's a big reason why my Collins ham station did NOT include a 180S-1. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 4/9/2015 4:00 PM, Ken Miller K6CTW wrote: > As a follow up to my earlier posting, here is a similar costing for the Collins S-Line in 1966 > > Unit > Number Description 1966 Price 2015 Price Equivalent > > 75S3-C RECEIVER $705.00 $5,107.00 > CW AND AM FILTERS (1 EA) $101.20 $733.00 > 312B-4 SPEAKER/CONSOLE $195.00 $1,413.00 > 32S-3 TRANSMITTER $750.00 $5,433.00 > 512F-2 TX POWER SUPPLY $115.00 $833.00 > 180S-1 ANTENNA COUPLER $640.00 $4,636.00 > > TOTAL Equivalent 2015 Cost $18,155.00 From dezrat at outlook.com Thu Apr 9 19:48:08 2015 From: dezrat at outlook.com (Bill Turner) Date: Thu, 9 Apr 2015 16:48:08 -0700 Subject: [Elecraft] The Cost Of Amateur Radios In-Reply-To: <11107200.1428618822547.JavaMail.root@wamui-junio.atl.sa.earthlink.net> References: <11107200.1428618822547.JavaMail.root@wamui-junio.atl.sa.earthlink.net> Message-ID: ------------ ORIGINAL MESSAGE ------------(may be snipped) On Thu, 9 Apr 2015 15:33:42 -0700 (GMT-07:00), you wrote: >Hmmmmm..... maybe the K3 is really a bargain after all! > >Just food for thought. > >73 - Ken Miller, K6CTW REPLY: A bargain? K3 is a good radio, no doubt, but for $2500 you can get a Flex 6300 which has nearly all the features and then some. You may want the external VFO knob @ $99. ATU is optional. A Software Defined Radio (SDR) not for everybody. It runs on your computer and there are no knobs on the radio except for the power button. If you like a radio with knobs for everything SDR's are not for you. 6300 Pros: 1. Already 100 watts, no separate amp needed. 2. Panadaptor built in (bigger screen and more versatile than the P3) 3. No filters to buy, including no roofing filters. The A/D conversion is done right at the antenna and bandwidth is adjustable to practically anything you want on any mode. 4. Receives short wave with no options needed. 5. Doesn't require any com ports at all. Everything is done via Ethernet port including PTT. Great for laptops without com ports. 6. No audio cables required for data modes. No Line In, Line Out, etc. All via Ethernet. 6 Hand mike included. Cons: 1. Doesn't do FSK, only AFSK. 2. Integrating with 3rd party programs is not easy but is doable. Some pulling of hair is inevitable. 3. Steep learning curve. Can be frustrating till you figure it out, but what radio isn't?. I have always thought the K3 was overpriced for what you get. Opinions will vary. My K3 + P3 is for sale. 73, Bill W6WRT From eric at elecraft.com Thu Apr 9 20:10:55 2015 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Thu, 09 Apr 2015 17:10:55 -0700 Subject: [Elecraft] New synthesizer shipping status?

(This was a huge number..) There might be a few orders that didn't make it from the 27th, but not many. We about halfway through the total upgrade order backlog, and the new order rate remains high for these going forward. (Thanks everyone!) We now have short pause in KSYN3AUPG shipments as we have outrun our initial production schedule and initial pull-ins of product as of today. We should resume shipping these in a week and a half, about 4/22, when our next major group of boards are ready. We received an incredible number of orders in the first several weeks, which is why may seem that we may be slowly moving through the order dates as we ship. There are a very large number of KYSYN3A orders for each day. When we saw the number of orders coming in that first week (which were well above the large amount we expected and planned for), we immediately and dramatically increased our parts and pcb material orders, and pulled in as much as possible from our existing pipeline of material and assembly orders. We have repeated that process as we have received even more orders above plan. Note that the time from new parts ordering to finished volume deliveries of boards takes between 6-8 weeks for the first finished boards to arrive and be tested. And once the new boards start to arrive, we are also also limited based on what our outside pcb assembly house here in Monterey, CA,, can produce daily. We also allocate the Synthesizer boards to three distinct areas at the factory. All three of the above areas independently ship based on the order dates for each group. a) K3 Production: Our first focus is to continually support K3 orders. We do not want to go dry and stop revenue from one of our primary products for an extended time. We have allocated inventory of KSYN3As to keep new K3 orders shipping on a continual basis, even when we run dry in the areas below. (Even with that buffer, its always possible we could have delays in K3 shipments of up to a several weeks if new K3 order rates exceed our planned KSYN3A inventory.) b) KSYN3AUPG orders: This group gets by far the overwhelming majority of new synthesizers, dwarfing K3s. These resume on about 4/22 as noted above. c) We also independently allocated a very small number of new Synthesizers to our K3 repair group. They handle all repairs and K3 upgrades done at the factory. This is small number of synthesizers and does not significantly impact K3 and KSYN3AUPG shipments. A key goal for us is to always return K3s to customers as quickly as possible to minimize their down-time. I think I counted less than 5 synths available in this group this morning. After those are used we'll have to wait until the deliveries start again 4/21. (Also note that the customer post earlier in this thread that seemed to indicate an out of order upgrade board shipment was actually for boards added to a radio in here for an existing repair and upgrade. It was not for a new KSYN3AUPG individual board order shipment from group B above.) Lastly, outside of our automated order reply you will not be contacted by us until you receive our shipping notice via UPS, USPS etc., or if we have a problem charging a credit card . There are just too many orders for us to manually contact everyone on backlog with status, and unless your order is close to the head of the queue, its also difficult to accurately predict the exact date it will ship. The best place to look for current KSYN3AUPG status is our shipping status page at: http://www.elecraft.com/elecraft_shipping_status.htm (We'll update that page with the above info shortly.) As our shipping status changes, we'll update that page. We are running fast buying KSN3A parts, boards, assembling and testing these as quickly as possible. Thanks again for your great response to this upgrade! 73, Eric elecraft.com ===== On 4/9/2015 2:34 PM, GRANT YOUNGMAN wrote: > Relax .. have a Mai Tai, eat some sashimi, stick your feet in the water, watch a sunset. > > It will ship when it?s time to ship ? > > >> On Apr 9, 2015, at 4:01 PM, David and Dianne on Comcast wrote: >> >> Hi Dave, >> >> Same here.

There is some magic in coming into a room by the light of the vacuum tubes, having to peak the output matching network every time you change frequencies, and having AM be a natural mode. I'm glad we still have enough bandwidth available so these old radios can be used on the air. And I'm glad there are people who love them and keep them running. However, for my own operations, I'll stick to newer radios which give better performance with less care and feeding. 73 Bill AE6JV On 4/9/15 at 4:31 PM, bsusb at k5dkz.com (bs usb) wrote: >Could that be why boatanchors have become obsolete and undesirable? ------------------------------------------------------------------------- Bill Frantz | Re: Hardware Management Modes: | Periwinkle (408)356-8506 | If there's a mode, there's a | 16345 Englewood Ave www.pwpconsult.com | failure mode. - Jerry Leichter | Los Gatos, CA 95032 From w3fpr at embarqmail.com Thu Apr 9 20:15:06 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Thu, 09 Apr 2015 20:15:06 -0400 Subject: [Elecraft] Collins S-Line Comparison In-Reply-To: <55270BC0.3060105@k5dkz.com> References: <31587653.1428620453602.JavaMail.root@wamui-hunyo.atl.sa.earthlink.net> <55270BC0.3060105@k5dkz.com> Message-ID: <5527160A.9030909@embarqmail.com> Hoping I don't hijack this thread and send it off in another direction, but I do have to comment on that statement below. In my neck of the woods, boatanchors are not "obsolete and undesirable". Many are sought out by buyers for the 'fun of restoring and operating them'. I know at least 10% of my local ham club is doing just that, and several other ham buddies and acquaintances. I take a walk through the fleamarket areas at hamfests and see many of those boatanchors being purchased. Those indeed are not "undesirable". I take that walk myself to satisfy my nostalgia - I see transmitters and receivers that I used to drool over in my younger days knowing that I could not afford them. I resist buying first because I do not have the time and commitment to restore them, but also because I know they would not perform (even after restoration) to the level I have come to expect from my K3 and KX3. I think about bring my own expanded version of the HBR-16 receiver from time to time, just to see how the selectivity of my double-tuned 85kHz 2nd IF filter really is compared with my K2 - but so far that project is still on the 'dream horizon' and may never be realized. In the meantime, the receiver sits in the attic. 73, Don W3FPR On 4/9/2015 7:31 PM, bs usb wrote: > Could that be why boatanchors have become obsolete and undesirable? > From n5ia at zia-connection.com Thu Apr 9 20:16:28 2015 From: n5ia at zia-connection.com (Milt -- N5IA) Date: Thu, 9 Apr 2015 17:16:28 -0700 Subject: [Elecraft] Collins S-Line Comparison In-Reply-To: <31587653.1428620453602.JavaMail.root@wamui-hunyo.atl.sa.earthlink.net> References: <31587653.1428620453602.JavaMail.root@wamui-hunyo.atl.sa.earthlink.net> Message-ID: I couldn't afford an S-Line then, AND I would not be able to afford an S-Line now.

I have worked many contests and weak signal DX in pileups with each, including a 6500 and I would choose the K3 every time for a variety of reasons. That is strictly my opinion, but for what I enjoy, I think the K3 is the best bang for the buck out there. My K3 isn't well loaded, but it does all I want until I get 2nd Rx or go so2r with another K3 which is likely. The KX3 is also on my I will get someday list.

At one end of rotation of R2 (the bandwidth pot) you should have near 6 volts on the cathodes of D5 and D6, and at the other end of rotation you should have near zero volts. You can measure with your DMM. I suspect you have zero volts all the time. 73, Don W3FPR On 4/9/2015 2:43 PM, Kenneth Talbott wrote: > Even in the extreme counterclockwise position of the Filter pot, the > width is TOO wide.

The first generation of Flexes were usable only by SSB rag-chewers, that is until they were obsoleted by changes in the windows computing environment. The current ones may be better, but for DX and contests you can't operate with a mouse. To make a Flex competitive with a K3, if it can be done, winds up making it cost more and you still have an inferior operating experience.

But the Flex equivalent of the K3 RX is the 6700, not the low end 6300. It takes the preamps in the 6700 to get MDS equal to the K3. The cost of the 6700 is $7499, in particular due to the cost of the stuff to make the 6700 RX function work that well. I'm not at all sure that "all...and then some" really applies to the 6300, particularly if high function RX parameters are of use. Good luck with your choices and druthers. And remember the place to crow about Flex is on their reflector. 73, Guy.

(oh sure when I first got it I was enamored with it but quickly the came to an end). It requires a computer, so you need to factor in that cost, and most likely an additional monitor and video card that will support it (more cost). I found the lack of knobs extremely cumbersome, Having to be tied to a computer to use a radio became very tiresome, and impractical. I had to dedicate 1 monitor just to the Flex, and as yo said having to mess around with all the virtual software for serial and audio was a pain (I'm an IT guy for 25+ years so if it's a pain for me how about the guy who does not do it for a living) I know some love the Flex, but honestly after owning one I'll never own another...

K3 is a good radio, no doubt, but for $2500 you can get a Flex 6300 which has nearly all the features and then some. You may want the external VFO knob @ $99. ATU is optional. A Software Defined Radio (SDR) not for everybody. It runs on your computer and there are no knobs on the radio except for the power button.? If you like a radio with knobs for everything SDR's are not for you. 6300 Pros: 1. Already 100 watts, no separate amp needed. 2. Panadaptor built in (bigger screen and more versatile than the P3) 3. No filters to buy, including no roofing filters. The A/D conversion is done right at the antenna and bandwidth is adjustable to practically anything? you want on any mode. 4. Receives short wave with no options needed. 5. Doesn't require any com ports at all. Everything is done via Ethernet port including PTT. Great for laptops without com ports. 6. No audio cables required for data modes. No Line In, Line Out, etc. All via Ethernet. 6 Hand mike included. Cons: 1. Doesn't do FSK, only AFSK. 2. Integrating with 3rd party programs is not easy but is doable. Some pulling of hair is inevitable. 3. Steep learning curve. Can be frustrating till you figure it out, but what radio isn't?. I have always thought the K3 was overpriced for what you get. Opinions will vary. My K3 + P3 is for sale. 73, Bill W6WRT ______________________________________________________________ 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 hlyingst at yahoo.com From dezrat at outlook.com Thu Apr 9 23:57:57 2015 From: dezrat at outlook.com (Bill Turner) Date: Thu, 9 Apr 2015 20:57:57 -0700 Subject: [Elecraft] The Cost Of Amateur Radios In-Reply-To: <851616663.37985.1428637010604.JavaMail.yahoo@mail.yahoo.com> References: <851616663.37985.1428637010604.JavaMail.yahoo@mail.yahoo.com> Message-ID: ------------ ORIGINAL MESSAGE ------------(may be snipped) On Fri, 10 Apr 2015 03:36:50 +0000 (UTC), Harry wrote: >I know some love the Flex, but honestly after owning one I'll never own another... REPLY: I suspect you owned an older model. The 6000 series is a different breed. As I said in my original post, not everybody will love an SDR. The main reason I like the 6300 is the panadaptor. The P3 is good, but the 6300 is better. My main response was to the fellow who said the K3 was a "bargain". I still disagree on that. I have almost $4000 into my K3 and P3, and that's without an ATU.

That leaves lead "B" of the KXB3080 to connect with hole "A". Did you have good receive when you tested the installation with the original L1 and L2 in place? Hopefully you did not skip that step. If you had good receive at that point, then the wires of the KXB3080 board are correct. Most problems with the KXB3080 option come from the Low Pass Filter board. Be certain that you have good stripping and tinning on the toroid leads. Look at the solder side of the LPF board - if you see any evidence of wire enamel on that side, or if any toroid lead has a ring around it, that lead was not properly stripped and tinned. In addition, take a look at the green lead on L2. It must route to the rear of the board without coming in contact with L2 lead 4 on either side of the board. 73, Don W3FPR On 4/9/2015 8:43 PM, Kenneth Talbott wrote: > Very helpful Don.

FWIW I have a K line, and a flex 6500. Flex has some more homework to do before their platform is fully contest ready. But they are working on it and I really see it as a work in development, many of the control knob and button issues have been addressed adequately with apps(ipad) and the flex control knob and the pan display is nothing short of amazing. I have gotten major contest loggers interfaced successfully. The 6300 is an entry level rig and as such will not hold up too well in battle with its lack of preselectors. The 6500 has preselectors but only 1 FPGA spectral capture unit.. (e.g. no diversity) only the $7000+ 6700 has diversity capability but both the 6500 and 6700 can replace 2 K3's with various SO2R tasks and that could make it attractive and a possible good value. Their most recent software update has supposedly cleaned up their tx..(I just committed tonight to bring my 6500 over to YC for a test) After running the lot.. I still show up to a contest and do my serious dxing with my K-line. but the improved capability of the 6500 is quite intriguing.. (and it has improved significantly). Its ability to produce its feature set remotely is pretty far out as well. I think this thing could develop into a contest friendly rig with future updates.... or then again.. we shall see. But hey it the operator and not the rig right? :-). Summary: Love and live by my Elecraft rigs. (Particularly my k-line. wont sell them.. no way no how) Intrigued with my flex 6500 experiment.. could grow on me if they makes various specific improvements. Their eco-system(reflectors.. support) also need work along with the rig itself. IMHO There are many lessons they could learn from the Elecraft eco-system in general. 73 Chris N6WM -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: Thursday, April 9, 2015 11:46 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] The Cost Of Amateur Radios On Thu,4/9/2015 4:48 PM, Bill Turner wrote: > Cons: You left out the fact that the K3 is a MUCH cleaner rig than the 6300 tested by ARRL, the Flex radios have only one RF chain, so they cannot do diversity, and the UI is something that only the programmer's mother could love. :) People buy radios for different uses.

Your going to somewhat stress a regular "wall-wart", if you use one to run a Thunderbolt, they are quite juicy in their power requirements, and also need multiple DC voltages. + & - 12V, and +5V Check the datasheet at Trimbles site (Google for it.) They run quite warm too, so if you put it in a box, make sure it has enough cooling, but you don't want the temperature to vary too much over time either. In any case, "Wall-Warts" are the scurge of the earth, most are poorly built, many don't conform to all the needed safety and/or EMC regs, many to fail early in life, compared to "regular" PSU's. They are a cheap (and nasty) solution to a simple problem, plus many are as some have found, poorly regulated. Most of the Thunderbolt "Kits from China" come with a suitable wide input range fairly quiet SMPS and ready made power cable for that to plug into the Thunderbolt. Note also, that unless you also obtain suitable software to configure and monitor the TB (Trimble's or "Lady Heather") it's going to be a bit of an uphill struggle to get it all working the first time. Remember too, that the GPS antenna will need a clear view of the sky for the TB to function correctly. "Have Fun!" Dave G0WBX.

For one, it shows the state of most settings all the time. For example, on the K3, to see the power level, you have to turn the knob and even then the power only flashes on the screen for about a second. On the 6300 it's there all the time. In other words, the K3's display is seriously limited in what it can show. The 6300's is not. Again, I didn't intend to get into a flame war between radios.

I recently put my Drake R4a back on line. It was one of the top of the line receivers when I bought it in 1967. One thing I notice is how much more crowded the CW bands are. With the R4a I can tune across the band and hear signals about everywhere. With the K3, the signals are still there but there are empty gaps between them, lot of room to operated because of the higher selectivity that was probably undreamed of 50 years ago.

For casual ssb use, I think the Flex is awesome. For serious cw and contesting, I think the Flex's are lagging quite a bit, and the 6300 has serious shortcomings (they market it as a casual radio and it is exactly that). I also got tired of random lockups and weird things, and focus issues in windows, under heavy use during contests. All strictly personal choices, but I don't think a non standalone (requires PC) versus a standalone radio is an apples to apples comparison. For casual use, you may not see much need for a K3 vs a Flex and it may be a bargain to get a 6300. But just last weekend we took a 6300 to a local EOC to operate in a QSO party. The lack of a front end preselector vs the 6500 that we also took was highly noticeable. Visually, interference raised the noise floor 15db from neighboring stations in the building. On the 6500, there was no evidence of interference. (Preselector vs non). I took my K3 and outscored them all with zero interference. That is a 2000 dollar difference in just the Flex line there. Anyhow, it is all about personal opinion and how you use a radio, and for what purposes. Speaking of so2r, I am not sure the 6x series can do that. True so2r allows you tx on one rig while listening on the other. I realize you have multiple slices, but can you hear a separate freq while transmitting? If so, that is a Flex advantage. If not, that is so2v, and the K3 and lots of others can do that. I haven't tried that so I don't know if it does or doesn't. 73, Joe AB5OR -------- Original message -------- From: Bill Turner Date: 04/10/2015 7:55 AM (GMT-06:00) To: Elecraft Subject: Re: [Elecraft] The Cost Of Amateur Radios ------------ ORIGINAL MESSAGE ------------(may be snipped) On Thu, 09 Apr 2015 23:45:53 -0700, you wrote: >and the UI is something that only the programmer's mother >could love. :) REPLY: Don't be so quick to dismiss the UI. For one, it shows the state of most settings all the time. For example, on the K3, to see the power level, you have to turn the knob and even then the power only flashes on the screen for about a second. On the 6300 it's there all the time. In other words, the K3's display is seriously limited in what it can show. The 6300's is not. Again, I didn't intend to get into a flame war between radios. I only wanted to respond to the fellow who said the K3 was a "bargain" by pointing out that the K3's features could be had for a lot less money.

So was/is (still have them) my Swan Cygnet 270B, TS-140, and Icom IC-746. Each represented a significant technological step forward. A year or so ago, my XYL and I decided to start planning to move out of our rural QTH to something more convenient considering our ages and my health issues. I thought it was important to downsize the collection of transceivers. I decided to sell the K-line and go with the rather pricey but well-designed "I" line. After a year or so of exclusively using this setup, it became extremely clear to me that I had made a mistake. As nice as this station was, there were many irritating flaws that kept bugging me. I quickly sold the "I" line and repurchased a K-line. Over the past 20 years I have a bought and sold just about every significant radio on the market. It's hard to compile a list of features that make the K3 standout in the large field of competent products. I had a few favorites like the TS-850 that just seemed to contain some kind of magic that made it stand out in a way that is nearly impossible to define. The K3 receiver obviously is virtually unmatched. But there is so much more. The best way to sum it up is to say that the K3 user interface was designed by someone who had enormous experience operating a transceiver in all types of conditions and who knew what parameters needed to be adjusted easily and quickly and which took a second level of priority, and which a third. Design based on pure experience rather than a committee. I tried a Flex. It is a nice radio. But being tethered to a computer all the time makes it not so much of a "Flex"able platform. When I unhook my K3 and carry it someplace else to use, it contains everything I need. and it's so lightweight compared to others which makes it ideal for porting to a second location once or twice a month. Let's face it - the K3 is the industry benchmark. Others that have tried to match it produce products that only come close and cost twice as much. 73, Doug -- K0DXV On 4/10/2015 8:44 AM, Tony Estep wrote: > On Fri, Apr 10, 2015 at 8:51 AM, Joe Moffatt wrote: > > For casual ssb use, I think the Flex is awesome.... > > ============== > Yup.

The thread was about how the K3 isn't comparable in price to the new 6300 series. The arguments have been made about how that really is or isn't the case. It is also a testimony to how strongly most of the users on this list feel for their K3. So it is about Elecraft.

I really enjoy them both. It does not have to be one way or the other. And for my use, they work equally well. The real answer is, a man needs one of each. I would like to have a K3 or what ever else Elecraft sends us. I worked a guy last night on Olivia with 7 watts on the Flex, he was using a FT-817 running 2 watts. It was a lot of fun for 45 minutes. Made me want to run the KX3 in its place but I was already committed to the QSO, I did not want to error switching rigs. I say this because it was not the hardware that made it fun. It was a wire antenna, a mode and a good operator on the other end. See you guys in Visalia next week. 73, Dan KM6CQ -- From todd at ruby-wine.com Fri Apr 10 13:14:39 2015 From: todd at ruby-wine.com (todd ruby) Date: Fri, 10 Apr 2015 13:14:39 -0400 Subject: [Elecraft] 50 W dummy load with UHF female connector Message-ID: <753F9404-8159-4764-A9BE-1DA0EA04E34C@ruby-wine.com> Hi, Can anyone recommend what they feel is the best 50 W dummy load with a UHF female connector that I can use to make K3 TX calibrations? thanks todd WB2ZAB From g1mhu at hotmail.com Fri Apr 10 13:19:16 2015 From: g1mhu at hotmail.com (Robin Moseley) Date: Fri, 10 Apr 2015 18:19:16 +0100 Subject: [Elecraft] 50 W dummy load with UHF female connector In-Reply-To: <753F9404-8159-4764-A9BE-1DA0EA04E34C@ruby-wine.com> References: <753F9404-8159-4764-A9BE-1DA0EA04E34C@ruby-wine.com> Message-ID: buy a 100w one from ebay etc.. it does not need a uhf female connector, make up a patch cable.

I guessed you missed my first sentence: "I am using a Morion OCXO as 10-MHz reference..."? The Double-Oven may be more stable at 2xE-12 vs mine 5xE-12 but doubt you will ever measure the difference let alone discern it in actual use (unless you are operating on high freq microwaves). Mine is single-oven, model MV62. I use a LM7805 for the Vf lead using a 10-turn Helipot (think it is 100K). The frequency control input takes very little current. My counter only resolves 1-Hz so I can only guess how close I have it adjusted (but less than a Hz). Actually, I can adjust it by monitoring my 3400-MHz transverter LO which is a PLL referenced to the OCXO. The LO runs at 3255-MHz which is several multiples above 10-MHz, so if it reads exact then the reference is much more accurate than 1-Hz ( depends on the divider ratio in the PLL). I float charge a 17AH battery so the voltage level is regulated by the battery (an the Astron PS). Advantage of the battery is that the OCXO is immune to power outages, so it remains very stable. Long-term stability is about 5xE-8 (28*5/100 = 1.4 Hz per year at 28-MHz) so one should check for drift about every six months. I use my Rubidium as my local frequency reference for this. I only run it for about an hour to be stable for the check. My mw counter is connected to the Rb for ext ref. I bought my Morion for about $45 a few years ago on e-bay. Recently I bought two sine-wave OCXO for $27.99 with free shipping from a Chinese source on e-bay; too two weeks to arrive. 73, Ed - KL7UW At 04:29 AM 4/10/2015, David G4DMP wrote: >Ed & others - > From my experience in using Rubidium and GPS disciplined standards, I >feel that a far better bet is to use an MV89A 10MHz Double-oven CXO.

At the time of my decision (May 2010) the main contender was the Flex5000. A lot of eme'rs bought the Flex, but I decided to listen to the HF CWers and bought my K3/10. What is nice is one can order their K3 optimized as they want by buying the options you will use. I do mainly VHF-eme so I did not need a 100w HF amp; in fact I do not use the 10w amp very much as transverters run on 0-dBm XVTR I/F. I did want the better TCXO and bought a few filters (ended up selling one of them), bought the KRX3 subreceiver, but no ATU (I had two manual HF tuners). My total before shipping was $2863. Definitely the most I ever spent on a single ham radio. I robbed my 401K for the funds (promising my wife it was the last ham radio of my life - I lied as I bought the KX3 two years later). I think customer relations of Elecraft are superb! And so far the firmware upgrades cost me nothing - the promise of a "forever SDR" was kept. Yeah, the new SYNTH will cost me a little - but not another $3K. I do not need a K4. My previous radios were a FT-847 and FT-817, FT-840 before that and a Tentec Scout, TS180S, Tentec Argonaut 505 ....heathkits (some I built). To date, no buyers remorse for me! 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From vk1zzgary at gmail.com Fri Apr 10 14:38:39 2015 From: vk1zzgary at gmail.com (Gary Gregory) Date: Sat, 11 Apr 2015 04:38:39 +1000 Subject: [Elecraft] K3 hand mic In-Reply-To: <5526C4B8.8020805@nycap.rr.com> References: <5526A58D.7010807@embarqmail.com> <5526C4B8.8020805@nycap.rr.com> Message-ID: I just got out of hospital after a stroke.....lots of things I would like better.....a mic is not on my list. :-) On 10/04/2015 4:28 AM, "Bill" wrote: > Thanks for the hints and Don's full explanation. 20/20 hindsight and > Elecraft could have prevented the problem by not designing a hand mic for > VOX (why would anyone do that anyway?) > > I have ordered the 514B. > > Bill W2BKC K-Line > ______________________________________________________________ > 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 vk1zzgary at gmail.com > From wocz at i29.net Fri Apr 10 15:24:02 2015 From: wocz at i29.net (wocz at i29.net) Date: Fri, 10 Apr 2015 14:24:02 -0500 Subject: [Elecraft] K2 plus KPA/KAT for sale.

The exchange is name and S/P/C for out-of-state stations, county for NM stations. We have 33 counties, some of which have zero hams, many without HF operators, and we'll have them all covered. Three of us from the Albuquerque DX Association (KK6MC, N5SJ, and K8TE) will cover all but two of the counties. You can follow me (most of the time) on APRS at http://aprs.fi/info/a/K8TE-1. I plan to beacon my current HF Frequency and county (counties in a couple of instances). I'm covering several from where this is no HF operations, so please give me points, especially those 2X CW ones! I will operate my K3-1 while the K3-2 sits at home ready to work DX when I return.

But- I don't believe there is any way they could add all those additional bands (with the filtering components required), plus higher output power on internal batteries, plus an extended range auto-tuner and still fit within the same size box. Elecraft has some great design folks, but... you'd have to give on that size "requirement" to stand a chance of ever seeing the others. If you admit it would take a larger box, then you are close enough to the KX3 to not make it worth the development costs. 73, Bruce N1RX From aa1sb at comcast.net Fri Apr 10 18:31:31 2015 From: aa1sb at comcast.net (Neil Collesidis) Date: Fri, 10 Apr 2015 18:31:31 -0400 Subject: [Elecraft] k3 kx3 memory editor rejects 60 meter entries Message-ID: <55284F43.8060000@comcast.net> I've spent enough time searching and playing around that it's worth asking the group: Is there a workaround for putting 60 meter frequencies into the K3/KX3 Memory Editor?

Coverage of 15m is essential, and 17m would be nice. The ATU capability needs great improvement beyond the 254 possible reactance combos in the current model. A noise blanker would be great. But...the most important thing: Design all of this from the start as a straight-forward system without a bunch of tricky add-on boards. Implement it with PCBs the way MFJ (yeah...I know) did their QRP Cub rigs...with most components as pre-installed SMT. Those Cub rigs were very quick to assemble and looked extremely neat...too bad the Cub RF design was so marginal. No fear of that with Elecraft. Mike / KK5F >Obviously, there is no KX2..

I have an FT-857 now, my first radio purchased from an SK?s XYL, great little radio, but I don?t use it portable only as a base. I really want to move up to something else that suits my needs and likes better. I really am impressed with all that I read on the Elecraft forum here. I have build many Heathkits in my earlier days including their first color Digital TV. So building the Elecraft K3 is just another plus for me, the personal touch to build my own transceiver, to become knowledgeable of it?s design and adjustments really is appealing to me ; not to mention the expert advice not only from a high quality made in America company experts, but the excellent advice from K3 owners worldwide. What price to place on that ?

It is easy enough to record the frequency memories from the front panel. First set to the frequency/mode/etc. that you want on the radio, and then refer to page 16 of the K3 manual (page 17 if dealing with the KX3) and follow the simple instructions to store those settings into memory, and tag them with labels if you so desire. I long ago saved the 60 meter channels into my K3 memories for channel hopping and have not touched them for years. You might want to look at the channel hopping and scanning sections in the manual as well - it makes operating on the channelized 60 meter band much easier. 73, Don W3FPR On 4/10/2015 6:31 PM, Neil Collesidis wrote: > I've spent enough time searching and playing around that it's worth > asking the group: > Is there a workaround for putting 60 meter frequencies into the K3/KX3 > Memory Editor? > It rejects them. > Thanks es 72, Neil aa1sb From mzilmer at roadrunner.com Fri Apr 10 19:00:26 2015 From: mzilmer at roadrunner.com (Matt Zilmer) Date: Fri, 10 Apr 2015 16:00:26 -0700 Subject: [Elecraft] k3 kx3 memory editor rejects 60 meter entries In-Reply-To: <55284F43.8060000@comcast.net> References: <55284F43.8060000@comcast.net> Message-ID: Hand entry, using the KX3's controls?

I'd like to add a little to what Dave has said. >Remember too, that the GPS antenna will need >a clear view of the sky for the TB to function correctly. Many GPS antennas are sold with a pre-attached coax. Most antennas contain a preamp as well. Ever wonder why? The coax supplied by many is very small allowing it to be easily concealed in a car's headliner. In an apartment or basement shack the distance to clear view may beyond the pre-supplied coax. Before you extend that coax take a look at the total attenuation. The GPS frequencies are approximately 1.6 GHz. At 1.6 GHz the attenuation of the OEM coax used by many runs about 1 db per foot. RG174 is 0.35 and RG58 0.2 db per foot. You can also figure about a db per connector. With this kind of attenuation a preamp is essential. Even with a preamp a long run of coax is deadly to GPS. Caveat Emptor. 73, Fred, AE6QL ______________________________________________________________ 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 fptownsend at earthlink.net From eric at elecraft.com Fri Apr 10 19:41:18 2015 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Fri, 10 Apr 2015 16:41:18 -0700 Subject: [Elecraft] The Cost of Amateur Radios In-Reply-To: <74d0a.12566851.4259adf2@aol.com> References: <74d0a.12566851.4259adf2@aol.com> Message-ID: <55285F9E.8010609@elecraft.com> Looks like this one has now been beaten into submission..

Started at the age of 15 (so go figure - the math is easy). I was 'playing with tubes' at that time and built my first transmitter from an ARRL handbook design. I used it through my novice year and later as a General. After that, I began to build receivers, something few amateurs attempted at that time, but I did not have the funds to buy a good receiver. I scrounged surplus parts because they were easily available as WW II surplus and you could buy a BC-453 for $5 at a surplus store. When I was in college, I had a BC-348 receiver and wanting to get something on the air from my dorm room, I built a 10 meter transmitter from WW II transmitter components and had a lot of fun on 10 meter AM with an antenna hung out the window of the dorm. In today's hindsight, I would like to have some of those BC series receivers and transmitters I stripped for parts because they fetch a 'pretty penny' on Ebay and other sources today. But I got value out of them, so I have no regrets. I even have several 85 kHz IF cans in the attic should someone want them - I hate to see them go unused, but modern components and crystal filters do a better job today. I gave up tubes sometime in the 1980s when I began converting tube radios to MOSFETS, and have never turned back. 73, Don W3FPR On 4/10/2015 7:55 PM, kevinr at coho.net wrote: > I am too - I did not start playing with tubes until 1958. > Kevin.

I just felt more comfortable doing that to power-up the new unit rather than using a bench power-supply. I'm ready now to do the next phase "Calibration" with the KX3-Utility code. However, Cady's book for the KX3 suggests that the "Calibration" should be done with a stable bench power-supply. I wondered if I must remove the internal batteries prior to connecting up the bench power-supply. (I do not have the KXBC3 battery-charger option.) I did not find an answer in the manual or Cady's book nor did searching through the schematics yield an answer for me. The problem is basically academic because the batteries will be removed with virtually every intent of leaving the KX3 that way permanently. (Of course, that is open to change based on future experience, in which case NiMHs would be installed.) I have my eye on a 12V 7A SLA to supply external power when operating portable.

Don't bother asking?how I?know this. ?:>) 73, Guy On Saturday, April 11, 2015, Johnny Siu wrote: ?Hello Group, This morning, I installed the new KSYN3A to my colleague's K3/100.?

I then discovered that the supply power voltage was 15.7v as indicated in the VFO B display (I later turned it back to 13.8v for further testing). Apparently, the installation of the new KSYN3A should have no relationship with the TX problem.? Since the K3/100 did not deliver any power, TX calibration could not be done. I tried to put the setting via the MENU of KPA3 to PAIO ON or PA BYP or PAIO BYP but still no TX output.? The KAT3 was set to BYP as well.? All test under a Bird 50 ohms dummy load.

The problem I see is the plethora of do everything packages(logging, rotor control, wash dishes, etc.) I did not find a software that really did a good job at rig control. Hence, I use an old (free) version of Ham Radio Deluxe that does most of what I want for rig control. The best add-on for rig control I have found is the Pigknob - with 8 programmable buttons and a 2-speed VFO knob. Be careful when testing some of these software packages. I experienced having to reset all my menu choices (equalizers, AGC, DSP, etc.) after using them. It appears the settings were changed by the software.

I see some functions that an on screen button can speed up, such as changing power levels. but most of the time I prefer using the rig rather than the mouse. That's one reason I prefer operating the K3 vs. the FlexRadio. The main thing I want a computer involved for is logging, digital modes, and multi unit synchoronization (such as the KAT500 with either the K3 or the Flex 6300.) But for routine operating, changing frequency or channels, changing CW speed, etc. I much prefer the rig vs the computer.

For some it is nearly a necessity - as is my case. To reach my rig's controls I must reach across my desk's writing surface. Perhaps hard for some to understand, but that can, at times, be challenging for me. Hence, being able to use a mouse at the edge of the desk - or the Pigknob in the same position - is a great advantage. I use an older version (free) of HRD to act as my memory manager - with its visual indicators on the band displays. The best option for my particular operation is the TS480 - with a small faceplate that can be positioned at the edge of my desk. That method provides full rig control as it was intended - without any software or hardware addons. Elecraft offers no simple/affordable answers for this. However, the K3's performance tends to spoil your acceptance of other rigs. So............. I use the Pigknob and HRD combo. I have tried all the available methods and, thus far, have found what I am using to be the best means of fully enjoying my K-Line. My 2-cents worth from my world.

If you have to use RIT when you change filters, then your filters are not set up properly. If you need information on setting the K2 filters, refer to my website www.w3fpr.com article on K2 Dial Calibration. The frequency shift between filters might be as high as 20 Hz, but that is not audible in SSB but can be noticed in CW, but is still not enough to require RIT for correction. If you observe significant drift during a long QSO (and you have not changed filters), then you have a problem with either the BFO frequency changing or the PLL/VFO changing frequencies. A K2 above SN3000 should have the new BFO inductor and the Temperature Compensated PLL which normally produces a stable frequency. If your K2 is earlier than SN 3000, add those upgrade kits unless they have already been added. A bad solder connection can cause jumps in frequency as can bad BFO crystals or a bad PLL crystal. The most common problem is a bad solder connection - bad BFO or PLL crystals are low on the list of suspects. 73, Don W3FPR On 4/11/2015 12:13 PM, Bernie KF0QS wrote: > Dear OM's and YL's: > > Twice, I've had people tell me my K2 (which I've had on the air for over 3 > years) drifts a bit in frequency.

With regard to Don's suggestion about improper filter setup, I have redone the filters several times, always following the instructions on Don's website. Always, I come out of that with the filters working properly, and only after a long time, I find I have to adjust the RIT in order to get the signal within the filter's bandpass. Since my serial number is above 3000, then that means that I have the new BFO inductor and the Temperature Compensated PLL Don refers to. Thus, I wonder if it is a bad solder connection. Where would I look for the bad solder connection? And also, is that the possible cause of my periodic need to readjust the filter settings?

What will the newer heat sink allow with the KX3? Still 5 watts or less, or will it let me go to 10 watts, safely, in these modes (or, PSK and RTTY)? I know it's better, but HOW much better? Second question: will the mic that can be ordered with the KX3 work on a K3? Right now, I am inclined to stick with my little KX1 for field operations. I like the KX3, but it seems a bit pricey to me for what I do.

Unfortunately, some of those connections are under the L33 BFO inductor. It is possible that you have a bad BFO crystal. But think about it a bit before doing anything to decide if it is the BFO or the PLL/VFO causing the problem. Since you have a significant shift in frequency, if you use the most narrow CW filter, has the audio pitch the same as you had set for the filter center, or is the pitch substantially different. You can observe the frequency at the center of the filter passband with Spectrogram. What I am getting at is that if the BFO is changing frequency, the audio pitch when the signal is tuned to the center of the narrow CW filter will be different than you chosen center frequency. OTOH, if the audio pitch stays the same, but you can retune (to that same pitch) with the RIT or by moving the VFO, then the problem is in the PLL/VFO area. 73, Don W3FPR On 4/11/2015 3:06 PM, Bernie and Cheryl wrote: > Dear Frank and Don: > > My K2 serial number is 6922. > > With regard to Don's suggestion about improper filter setup, I have > redone the filters several times, always following the instructions on > Don's website.

The KY command has characters that you want sent as a parameter. Therefore KY CQ; sends CQ with the keyer speed defined in the radio. So the characters entered in the terminal are sent with the KY command. The characters that are sent to the radio,? are sent at a slightly higher rate than what the radio sends so that the keyer is not waiting for a character. Decoding really depends on the quality of the sender. Machine generated code is decoded quite well. Human generated code, can be poor! Of course none of this replaces a knowledge of cw. Where it is useful is for the built in messages, and for remote operation using a keyboard and your tablet or even a phone. I have a confession though, I do not know cw but I have used this along with cw skimmer to make 50 new dxcc during the last CQ contest. Was a lot of fun.

Let the K3 get well warmed up. Tune in WWV at 15 MHZ in the CW mode with narrow 50hz filter. Tune slightly high and tap SPOT. The K3 should stop about 1 hz high in frequency. Tune slightly low and tap SPOT. The K3 should stop about 1 hz low in frequency. Set the K3 to the 1 hz step in between the previous two steps. If the K3 does not read 50.000.000 than go to the CONFIG menu and REF CAL. Adjust the frequency a bit and go back and do the tests. You should be able to get the high SPOT to stop at 50.000.001 and the low SPOT to stop at 49.999.999. Than the proper point should be set to 50.000.000. The unknown frequency should be measured by high tap SPOT and note the frequency than low tap SPOT and note the frequency. The unknown frequency will be close to the frequency step in between those two spots. This should easily get you within 2 hz of the unknown frequency. You can use the SPECTRUM LAB program to get even closer. The only reason the KX3 can get slightly better is that it only has the VFO and no IF frequency while the K3 has both the VFO and IF. That means more math takes place in the transceiver but there is also error in propagation so the end result is the K3 and the KX3 should be close. If you do not use the SPECTRUM LAB program then the above procedure should be about as good as you possibly get using your equipment. I hope these ideas help you and others to make a good showing at the next FMT. 73 and good luck Ken W0CZ w0cz at i29 dot net Sent from my iPad > On Apr 11, 2015, at 12:49 PM, wrote: > > We used just the K3 for FMT the first time.

Just for the fun of it I fired up the KX3 and to my surprise it did even better than the K3. I had run the temperature compensated frequency setup last year and I found it would go for hours and never move even 1 hz. I ran the FMT after helping teach the ham radio licensing test Wednesday evening. My results were +1.04 hz on 20, -0.14 hz on 40 and -0.77 hz on 80.

I see some functions that an on screen button can speed up, such as changing power levels. but most of the time I prefer using the rig rather than the mouse. That's one reason I prefer operating the K3 vs. the FlexRadio. The main thing I want a computer involved for is logging, digital modes, and multi unit synchoronization (such as the KAT500 with either the K3 or the Flex 6300.) But for routine operating, changing frequency or channels, changing CW speed, etc. I much prefer the rig vs the computer.

I can only hear the signal if I tune about 1 khz down, and then I do hear the signal, albeit very low in pitch as opposed to the pitch I heard before I switched in the filter. Given that, I suppose it sounds like the VFO is the problem?

You supply BNC cable to whatever your rig needs and power. LP-Pan is setup for K3. LP-Pan serial number is 1613, it has the high performance preamp. The LP-Pan2 can be used with any transceiver having an IF output. Transceivers other than K3 will require a different crystal to account for difference in IF frequency. There is a socket in place for the crystal and a set of jumpers to select the desired crystal. Larry, N8LP, has appropriate crystals for sale at a nominal price. Works great, no taste and less filling. A whole lot cheaper than a P3. Asking $210 shipped within USA, outside USA at actual cost.

In Basic operation mode, the KAT500 will measure frequency while you are transmitting and switch to previously stored tuning solutions for any of the three antennas. It will do this in about a dah's length of RF. You do have to train the tuner but you are probably doing that now. You can also use the KAT's enhanced tuning by making a cable to feed the band data from the Yeasu to the KAT500. Note that that just gives the KAT500 a heads-up when you switch bands. It still has to measure the exact frequency to get the correct tuning elements, so it may not be worth the trouble. Now this is assuming it will measure frequencies outside the ham bands but I would think it does. There is a blurb on how the KAT500 and KXT100 work on my web site. http://www.ke7x.com/home/kat500-and-kxpa100-tuners Cheers, Fred KE7X Author of: "The Elecraft K3: Design, Configuration and Operation 2nd ed" "The Elecraft KX3 - Going for the summit" "The Elecraft KPA500 and KAT500 - the K-Line Dream Station" Printed, coil bound copies of these are all available at www.elecraft.com KPA500 and KAT500 Quick Set Up Guide http://www.ke7x.com/home/k-line-introduction-and-set-up-guide KAT500 and KXPA500 Tuner Operation http://www.ke7x.com/home/kat500-and-kxpa100-tuners > -----Original Message----- > From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of > Amateur Radio Operator N5GE > Sent: Saturday, April 11, 2015 5:03 PM > To: Elecraft Reflector > Subject: [Elecraft] KAT500 connections for Yaesu FTdx1200 > > I use an FTdx1200 for MARS message traffic because my K3 cannot > transmit on the MARS frequencies in some parts of the HF spectrum due > to the K3's IF frequencies and I like my KAT500 very much, so I am > thinking about using an additional KAT500 as the tuner for the Yaesu > Rig. > > If there is someone out there using that combination I'd like to know > how it's working out and how the connections were made. > > Thanks for any feed back or comments regarding above, > > Amateur Radio Operator > N5GE > > ______________________________________________________________ > 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 fcady at ece.montana.edu From pf at tippete.net Sun Apr 12 12:27:22 2015 From: pf at tippete.net (Pierfrancesco Caci) Date: Sun, 12 Apr 2015 18:27:22 +0200 Subject: [Elecraft] K3 and remote antenna switches Message-ID: <87pp79ia6t.fsf@snoopy.tippete.net> Hello, I'm thinking of getting a remote antenna switch to be placed on the roof. I've found this thread: http://elecraft.365791.n2.nabble.com/K-Line-Antenna-switching-td7563906.html and it looks like the Array Solutions' SixPack could be a good solution. Browsing their application notes, I've found a mention of using it with a dual-receiver radio for diversity: http://www.arraysolutions.com/Products/diversityreciver.htm#top%20of%20page Is anyone using it with a K3 connected to both inputs? My idea would be to have vertically polarized antennas on one K3 input, and horizontally polarized ones on the other, but the SixPack seems to allow for further flexibility. How to control it? The dual-radio controller seems to assume 2 radios, each having its own rs232 or band-decoder. Will the controller itself need to be programmed by a computer, or can it be programmed entirely from pushbuttons/jumpers?

It begins early in mid February with the first flowers popping through the snow. Soon afterward the first of our two species of hummingbirds returns. Currently they keep an eye on me as I split wood; anywhere near the feeder or the salmon berry blossoms and I get buzzed. Next come the daffodils which are in their third week of blooming. The flowering dogwood trees have begun blooming at lower elevations but they are a few weeks away up here. Propagation has been improving mostly from lesser noise levels. The sun has been actively spewing ions in our direction with the solar wind frequently causing waves of noise. Between the waves of noise conditions are pretty good. Fiddling with NR settings can eliminate the QRN for a while until their characteristics change - then more fiddling.

If that is not effective, I would order new BFO crystals, a new Q24, and L33 - if you cannot salvage the 1/8 watt resistor and bumper stem, order BFOMDKT instead of L33. I would suggest replacing all of them to shorten the troubleshooting work unless you are dead set on discovering the exact source of the problem, which could take a substantial amount of time.

Hams asking these questions fail to realize that mics of the sort needed for our ham rigs are quite generic. Perhaps we can blame Bob Heil and the marketing hype that made him a "name" in ham circles, allowing him to sell his mics for 3-4X what they cost to make. Almost any electret or dynamic mic will work just fine with a K3 and KX3. We can choose almost entirely on the basis of the physical format of the mic and its cost. If you're backpacking, you want light, so buy a comfortable, compact, lightweight, easy to pack boom headset. For use at home, it's awfully hard to beat the Yamaha CM500, or a similar Koss model that I haven't seen but that some like. 73, Jim K9YC From challinan at gmail.com Sun Apr 12 20:28:04 2015 From: challinan at gmail.com (Chris Hallinan) Date: Sun, 12 Apr 2015 20:28:04 -0400 Subject: [Elecraft] Loud relay click on CW using RX ant only on some bands Message-ID: Hi folks I've been enjoying a new RX Loop antenna with my K3.

You have too much Transmit RF reaching your RX antenna. The cure is to move your RX antenna further away from your TX antenna, or use one of the several solutions that disconnect (or ground) the RX antenna during transmit. 73, Don W3FPR On 4/12/2015 8:28 PM, Chris Hallinan wrote: > Hi folks > > I've been enjoying a new RX Loop antenna with my K3.

I happen to use the Array Solutions product and it works great. But as you evaluate your possible solutions, consider that if your loop is near other antennas or large metal objects, it will to some degree 'couple' to them and your loop will not be working as effectively as it otherwise might. I use several magnetic loops here for receiving, and even my small 40' self-supporting tower acts as a noise/signal re-radiator, which is most noticeable when I'm trying to use the deep nulls of the loop to eliminate or reduce a local noise source. It frequently ends up with the best null on the tower -- even though I know the tower is not the originator of the noise. Since the null is on the tower instead, the noise from the true origin is still being picked up by the loop. Fortunately, the loops are small and easily moved, so you can experiment to find the best location. An easy way to test if a particular antenna, such as your vertical, is coupling to your loop is to alternatively short and then open the connector on the feedline to your vertical while listening to the noise floor of the band of interest on your K3 (the P3 helps a lot here too!). (make sure your antenna is not in the NULL of your loop though) If you hear a difference, there is some coupling. If not, you're probably not getting enough coupling on receive to cause any problems -- though you may still need to add the rx protection device to protect the K3 from excessive rf while transmitting. 73, Dale WA8SRA > Many thanks to all who replied.

Q24 is only active on TX, but is still in the circuit during RX.

I'm a bit confused about the TCXO and especially how to perform the calibration of it and would the upgrade to either the?KTCXO3-1 ?TCXO ?1 PPM or K3EXREF be a better choice? My guess on what the TCXO does is provide a stable clock to the synthesizer. Is that correct? And the more accurate/stable the better (hence the upgrade paths)? So I have the "standard" TCXO right now. I get lost on the instructions after step two which is to tune to WWV 20MHz.

On transmit, tuning C23 seems to be an on/off valve. On either side of a broad middle range power output is very low, about 300 mW. The transition to a full 10 watts or so is very sudden. Continued rotation it stays cons tant at that level until an instantaneous drop back down to the 300 mW level or so. Does this lack of a smoother change imply a problem with C23? I have occasionally noted that even after having carefully tuned this LPF that 20m CW power starts very low. After switching to another band and back it usually normalizes. This even transmitting into a 50 ohm dummy load. Seems it could be related to C23 behavior?

Besides this you always have the delay of the relay switching. Even if it is quite fast (not sure about the COR in the K3, might be 5 ms or 30 ms, haven't checked what type of relay Elecraft used), there is a moment of no isolation so it could still destroy the front-end. Whenever you hear the COR activating you should take it as the last warning and take according measures to cure the source of the problem, not it's symptoms. ;-) 73, Olli - DH8BQA Contest, DX & radio projects: http://www.dh8bqa.de Am 13.04.2015 um 18:48 schrieb Hank Garretson: > Help please. > > If the K3 is protecting itself, other than the noise, why is an external > protection device needed? > > 73, > > Hank, W6SX > ______________________________________________________________ > 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 droese at necg.de > From don at w3fpr.com Mon Apr 13 14:29:43 2015 From: don at w3fpr.com (Don Wilhelm) Date: Mon, 13 Apr 2015 14:29:43 -0400 Subject: [Elecraft] [K2] LPF tuning for 20m In-Reply-To: References: Message-ID: <552C0B17.6080701@w3fpr.com> Chip, Yes, the lack of smooth tuning indicates a faulty C23. You might try spinning the rotor around through 10 or 12 times and see if that helps. There may some dirt of corrosion on the rotor wiper contact. The power after a band change or a power level change normally starts out low and builds to the requested power after a couple dit times - that happens on all bands, but if you do not have good tuning of the 20 meter BPF, it may be more noticable than normal and take longer to come up to full power. 73, Don W3FPR On 4/13/2015 12:46 PM, Chip Stratton wrote: > Hi Don et al - > > I'm tuning up a K2 recently acquired from an estate.

If your K3 is operated in a shack with stable temperature, the only advantage over the standard TCXO is that there will be less frequency change during the K3 warmup time. You apparently are not a CW operator if you do not know how to "SPOT" a signal (or tune a musical instrument using 'beats'). Let me try to explain: When you turn on the sidetone, you will hear a tone at the audio frequency that you set using "PITCH". You will hear another audio frequency produced by the carrier of the signal you are tuned to - when using WWV, be certain you are hearing the carrier and not one of the other tones that they transmit. Normally in operating, one would tune the VFO until the two tones match - this is "Spotting" or also known as tuning to "Zero-Beat" The difference between normal operating and this procedure is that you tune the VFO to the frequency of the signal and then leave it there. You then adjust the menu REF CAL parameter to make the tones match. When the two tones are close together, you will begin to hear a pulsating sound (something like wow-wow-wow). When the pulsating slows the lowest rate you can achieve, you are at zero beat which is the desired condition. If you cannot hear the pulsating between the tones, either the two tones are not close to each other, the you can use a visual aid - an audio spectrum analyzer running on the computer with the K3 audio connected to the computer soundcard input. That will give you a visual of the two tones. Once you get the tones visually close to each other, listen for the beat note and slow it down to zero or as close to zero as you can obtain. 73, Don W3FPR On 4/13/2015 11:20 AM, Michael Gillen via Elecraft wrote: > Hello all, new to Ham (about two months) and just built my K3 over the weekend.

Setup KX3, KXPA100 Running 30W, PX3, OCD with standalone SWR 1.6 on 80M. tuned SWR 1.1 After about 10 mins sending CW, QSK went silent SWR went off charts and amp went into protection mode with Ant Fault warning. Shut down. checked SWR of stand alone ant 1.6 ( at input to amp) reconnected and turned radio back on, went into protect mode with Ant Fault. Checked display and noticed amp had switched to Ant2. I had Ant 2 disabled via utility, but apparently that was reset when I did an firmware update. Disabled Ant 2 again and switched to Ant 1 All is well. Not sure how ant switched as nothing was touched in KX3 or amp. -- View this message in context: http://elecraft.365791.n2.nabble.com/Interesting-Occurence-last-night-tp7601333.html Sent from the Elecraft mailing list archive at Nabble.com.

Would you also want to add its little bit different brother, the SPS-30DM. I have the 30DM with the digital voltage and current meters as well as variable voltage (if you need it). It also has a switched fixed voltage mode so no worries about dialing in the exact voltage level. I keep thinking that the more power supplies I own, the higher the power I can transmit into my antenna.

This is an excellent compact switching power supply, with two APP connectors on the front and binding posts on the rear. It is a great match for the K3 K-Line and the KX3 KX-Line and accessories. Note also that new K3/100s and KXPA100s come with power cables that have APP connectors on one end for the radio, and they now have pre-crimped ring lugs on the other end for easy connection to the power supply. We use the SS30DV here at the factory, and many of us use them at our personal stations (myself included).

I'm not sure if a 100% noise-free 30-amp switcher has ever been designed. If it has, chances are it would be far more expensive than this one.

According to Murphy the terminals will always be in the least convenient place so if you need them to be in front, they will be in the back. Incidentally I note they changed the specs in 3-2012. Was 25/30A @13.85V. Now its 25/28A @ 14.1V.

Fan is very quiet. I only ever noticed RFI when I had keyer powered by front PP and it was very low level. When I disconnected keyer no RFI noise found on the P3. I also had a ground loop problem, but grounding power supply, loop went away.

This is an excellent compact switching power supply, with two APP connectors on the front and binding posts on the rear. It is a great match for the K3 K-Line and the KX3 KX-Line and accessories. Note also that new K3/100s and KXPA100s come with power cables that have APP connectors on one end for the radio, and they now have pre-crimped ring lugs on the other end for easy connection to the power supply.

My concern would be RFI at 144-MHz and higher as my application is supplying two 60w linear amplifiers (class-A) that operate on 3.4 GHz. Each needs 20A continuous supply, so two PS will be needed. I don't care about fan noise as they will be installed on my dish 100-feet from the shack. I plan to switch the dc on/off to the amplifiers in Tx/Rx to minimize heat dissipation (240w each). Amps will have super heat-sinks with fans running continuous. I probably will run ac to the PS to have short dc lines (maybe I will run RG-59 to shield the dc). Do the back connectors thread all the way off for installing ring connectors? Some banana type do not forcing the use of a 1/4-inch spade vs ring. I would likely replace the banana with 1/4-inch nuts, locks, flat washers. I read some of the eHam reviews and there were several about HF RFI but most seem to note nothing at VHF. I will be running 144-MHz via coax to the dish where the transverter will be located. One question is how low voltage can be adjusted. Amps are designed for 12.0 volts. This looks like a nice package for portable use with K3/100. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From w0fm at swbell.net Wed Apr 15 10:49:22 2015 From: w0fm at swbell.net (Terry Schieler) Date: Wed, 15 Apr 2015 09:49:22 -0500 Subject: [Elecraft] New 30A power supply on Elecraft order form In-Reply-To: <552D6B2C.5030708@elecraft.com> References: <552D6B2C.5030708@elecraft.com> Message-ID: <002f01d0778b$5cefc000$16cf4000$@net> Great choice, Eric.

The bias is applied to mic pin 1 (the AF signal), not pin 6. If you are using that microphone with a K2 that is wired for bias, you will have to remove the bias resistor from pin 1 - remove the left side panel and lift the resistor from mic jack pin 1. You can leave the other end of the resistor in place in case you ever need to reattach it. Since you have bias still set on, that would be applying a voltage to the dynamic mike element and could reduce its output level. Remove the bias and check the mic level again. 73, Don W3FPR On 4/15/2015 11:42 AM, KK5IB wrote: > Bill, > Could I ask how does the MH2 mike compare to the 514B in level setting?

And notably Wayne posted: >>results with switching supplies can vary with type of antenna feed. >>For example, I wouldn't use a switcher if you have no choice but to >>use an random wire leading directly from window to rig. Good >>grounding can also help. I'm not sure if a 100% noise-free 30-amp >>switcher has ever been designed... As a manufacturer of a compact switcher for HF transceiver use, we have performed a LOT of testing on this issue. A short summary of our findings is on our website on the FAQ tab at: https://proaudioeng.com/products/pae-kx33-ac-power-supply/ To summarize, common-mode current due to antenna system issues does indeed play a role in apparent switching supply noise. Please read the FAQ for more. I don't want to post it here due to it's promotional content.

This includes the K3's and K2's internal 100-W amps as well as the KXPA100. They will certainly run from lower voltages -- down to about 10.5 to 11 V -- but for home use, we recommend setting the DC supply to 14.0-14.2 V. They'll run from as high as 15 V, though again, around 14 V optimizes power output, IMD levels, and efficiency. > > 73, > Wayne > N6KR > > > ______________________________________________________________ > 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 elist_copy at elecraft.com From jvandrey at gmail.com Wed Apr 15 16:36:54 2015 From: jvandrey at gmail.com (Jobst Vandrey) Date: Wed, 15 Apr 2015 15:36:54 -0500 Subject: [Elecraft] Linux and K3 Utilities Message-ID: I have been trying to run the K3 utilities on my Linux system (64 bit Ubuntu 14.04 LTS).

Then I increased my MIC to 45 from 35 and CMP from 20 to 25. Using the scientific process of using the mic for several days before asking anyone about audio changes to my signal, I operated as normal. No comments were heard during that part of the test and when I announced I had made a change, all agreed that it sounded the same as before - this is a good thing in my opinion. No changes were made to the TX equalizer from the HM2.

You're not doing anything "wrong". The Elecraft utilities are only built for 32 bit Linux at this time, as I understand it. Brendan gave good advice below to enable "multiarch" so that the 32 and 64 bit libraries can be installed and used at the same time. Personally, I didn't care for the aesthetics of that approach so I installed Debian 7 32 bit in a VirtualBox machine and I run the utilities from there. As I use the VM for other things and I don't use the utilities all that often that approach works for me. The nice thing about VirtualBox is that you can save the state of the VM--much like putting a laptop into suspend--and then everything resumes in a few seconds and when I'm done I save the VM again until next time.

This unit was originally sold in the US by Ten-Tec but now Vibroplex sells them. Price I paid for this one was $299.95 from Ten Tec (Vibroplex now sells them for $259.95 plus shipping). Mine has the Lithium Ion battery and charger that were originally sold as accessories and it has all been gently used, never dropped and lives in a non-smoking environment. Cosmetically it's a 9.9 out of 10. You can actually carry this up a tower in your shirt or jacket pocket and use it right at the antenna with a short cable and proper adapter. It comes with a printed copy of the manual, the BNC to SO-239 adapter and it will come in a really nice copy of a small waterproof Pelican case that Marlin P. Jones Associates sells for $17.95 plus shipping. You can see the case at http://www.mpja.com/93in-X-62in-X-35in-Waterproof-Case/productinfo/17813%20BX/ I'll let this one go for $235 shipped in the U.S. (I won't ship it internationally, sorry ----) Inquiries and requests for pictures to my email address ( w0eb at cox.net) off list please. First "I'll take it" by date/time of email gets right of first refusal. I take USPS Money Orders or PayPal only. If you buy it, it ships same day the funds arrive.

Mike - W0AG From matt.vk2rq at gmail.com Thu Apr 16 23:13:20 2015 From: matt.vk2rq at gmail.com (Matt VK2RQ) Date: Fri, 17 Apr 2015 12:13:20 +0900 Subject: [Elecraft] KX3 In-Reply-To: References: Message-ID: Normally you connect your paddle to the Winkeyer, and connect the Winkeyer to the KX3 key input in the left hand side, which is set in "hand key" mode. This way you can send CW from your PC, or interrupt the PC by sending on the paddle manually, and it all happens at the speed set by the Winkeyer. However, in this configuration, the KX3 can not decode your sending, and you can't use the paddle to send PSK31 or RTTY. In that case, you need to use the internal keyer. You can unplug your paddle from the Winkeyer, and connect it to the keyer input at the front of the KX3. You'll need to make up a suitable plug to connect to the square four pins. But, if you have a PC connected anyway, you may as well use the PC for those digital modes (either via KX3 terminal or sound card). 73, Matt VK2RQ > On 17 Apr 2015, at 11:45 am, Mike Murray wrote: > > Maybe I'm confused, but is there any way to use the key jack on the KX3 for > both a K1EL keyer and a parallel paddle? > > Mike - W0AG > ______________________________________________________________ > 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 matt.vk2rq at gmail.com From k6dgw at foothill.net Thu Apr 16 23:41:14 2015 From: k6dgw at foothill.net (Fred Jensen) Date: Thu, 16 Apr 2015 20:41:14 -0700 Subject: [Elecraft] New Synth-LF Message-ID: <553080DA.9050004@foothill.net> Sun went down, so I tuned down to the Holy Frequency region, I just using my low band antenna, no tuner, and I'm hearing NBD's I knew were there but could never separate from the 80m leak through with my Palomar converter.

All came, however, from people who are using the combo with computer control and/or an Internet link. So I thought I would clarify what I meant to ask: What I am thinking of is having the mini mounted near the driver?s seat in my SUV, and the K3 (or even the K3/KPA500) way in the back, connected directly to the mini by a cable. The description of the mini on the Elecraft site makes it sound as if the two could be cabled directly together - without a Remote Rig or computer or anything else in between - but it isn?t absolutely clear; and it raises the question whether the RF noise circulating through the car would make a cabled connection iffy. So that?s the question - any thoughts, anyone?

There are those that continue to self promote themselves to the rank of moderator. But they don't have the passwords to the moderator's tools. One of the moderator's rules for the list users is to not to usurp the moderator. So don't want to read it, just delete it. Very fast, very efficient. Please enjoy yourself on the reflector. 73, Guy PS, I finally caved, the very last of my extended family mob to get a smartphone. The gmail app for the iPhone has a great sequence for mass deletion: Tap the mark on the first subject to delete, then tap the subject anywhere to mark the rest. I went through thirty some listed in about 15 seconds. Tapped delete icon, then read those that were left. Highly efficient, very fast, zero stress, wonderful.

Anyone know what that might be? Now that Middletown CA LORSTA is shut down, I'm hearing a whole lot of things down there.

Where is "there," Kimosabe? Currently reportable news includes: - The new synth for the K3 (KSYN3A), which adds 600 meter capability, virtually eliminates CW timing variance, and improves close-in phase noise. Lower phase noise results in even cleaner transmit. On receive it means better reciprocal mixing dynamic range (RMDR) and greater 3rd order IMD dynamic range (IMDDR3). Eric gave a talk on the synth improvements today, as they're highly relevant to many DXers. - We've been testing a new transmit-monitoring feature on the P3 panadapter, which provides simulated analog power and SWR meters as well as high-resolution transmit envelope display. We had hoped to have this in time for Visalia but now it's looking like Dayton. Various full-scale power ranges are provided including 200 W and 2 KW, using a transmit RF sampling unit based on the ones used with the W2 wattmeter. - Fixed-tune mode for the PX3 panadapter is ready for beta test, probably early next week. This feature has been very popular on the P3, and we've had help from a number of volunteers to get it dialed in on the PX3 (thanks, guys).

Many of the Prolific USB to serial adapters do not work well, particularly at the lower 4800 baud rate of the K2 (the K3 is usually OK).

Don is correct... try FTDI, and beyond that, try virtually every driver you can find for Windows 8 USB to serial. You never know which one might work, but I have found SEVERAL counterfeit pieces of hardware out there that you wouldn't expect. It may or may not be counterfeit, but there are tons of sources for bad pieces of hardware. Seems to really be an issue with Windows 8 moreso than 7, but drivers work a little differently in 8.

I just joined it a moment ago in an effort to get some help. I recently upgraded my K3 by adding the sub receiver to it. I built the rig myself, then used it for 5 months without the sub receiver, and just last week had the sub receiver installed and tested by Elecraft. That gives me some confidence that it should be working.except that I absolutely cannot figure out how to use it. Initially I tried to use it the same way I did the sub receiver in my old FT-1000MP, but I can tell this one doesn't work that way. If I simply tap SUB, which is what I would have expected, then the VFO B knob has no effect on what I'm hearing through the right headphone. The only way I have been able to get the sub receiver to behave like a sub receiver has been as follows: a. Set CONFIG:VFO IND to YES. Then set VFO's A and B to different bands. b. Tap SUB to turn the sub receiver on, then press and hold SUB to put it into diversity mode, then tap SUB again. If I do all of that, then I can hear a different frequency in each ear and the VFO A and VFO B knobs are respectively controlling the frequencies of what I hear in each ear. But that is nonsense! I have not been able to get the rig to do this when both are on the same band. What I want is to have both VFO's on the same band so that I can listen to the calling station on A and tune around on the pile-up with B, all the while being able to hear both frequencies. How do you do that? It is slowly becoming apparent to me that VFO A, VFO B, and SUB are three different things. I guess what I'm really asking is how do I get the VFO B knob to control the frequency of SUB? I have practically memorized pages 37-38 of the user manual and it's still not coming through for me.

"It has been asked time and again for a very simple reason but indeed it seems to be too difficult to comply for some..." People are wasting time trying to enforce 'rules' on a mailing list regarding product information in the subject, unless they are moderators and willing to start dropping messages that don't fit. I truly don't understand the effort expended in this thread over something solved by adding filters into mail clients/mail servers to sort KX3/K3/PX3/P3/KXPA100/K2/K1/etc into individual folders if it really matters that much. An earlier example was given on how to filter based on list, just add a body filter and you can have mail sent to whichever folder you want based on content. Short of an official rule that is ban-hammer enforced regarding subject lines, that's the best you are going to do. I have to be honest, this is starting to sound like the local HOA, and there is no reason for that.

In several places in Fred's book about the K3 he specifically tells the reader to read the owners manual. If I recall correctly the parts about configuration and calibration are two such spots. IMHO the sequence of events for a new K3 owner should be Aaaembly Manual if you bought the kit, Operators Manual and Fred's books in that order, before ever turning the radio on. For technical support Elecraft support, either email or telephone, and this reflector last. The first two will put you in touch with experts, the last, unless you get answers from about a half dozen or so people, and we all know who they are, not so much answers as guesses. Maybe it was a mistake for Elecraft to offer factory built K3's. People would be forced to RTFM to get the rig built. -- R.

What a great group? I had 5 offers of a loan for either a XG1 or XG2. Thank you. In discussing the seemingly dead deft KX3 receiver I tried changing the mode from CW to SSB and it started to work normally. Only indicated difference seen was the it changed from FL2 for CW to FL1 for SSB. Problem was this KX3 didn't have the optional filter installed. Phil suggested I check the RX Fil configuration setting in the menu. Doing this found it was set to "Auto". Changing it to "Not Inst" and the KX3 receiver started to work normally. Have no idea how the menu item got changed. I'm a very happy camper. Thanks to all for the help.

With so many email lists I'm signed up for, it's hard to keep track of the ones that either bounce HTML-formatted messages, or just strip it off, like apparently this one did. Here goes: I ran my K3 with the new KSYN3A boards on the MI QSO party for about 10.5 hours yesterday, the first SSB event I've done with the new boards (prior CQ WPX CW for a couple of hours worked fine, using S&P). I spend long periods of time camped out on various frequencies/bands, calling CQ MiQP and working stations. I noticed a number of callers coming back to me off frequency by a couple of hundred hertz, and started 'chasing' them with the RIT, which only seemed to make matters worse. When they came back each time, it seemed they were on a different frequency. Eventually, I had two different stations tell me (without prompting) that my transmit frequency was shifting around, and that they were chasing me around! One station thought maybe I had mistaken my XIT for my RIT (nope). Not knowing what to make of it, and being in the middle of the QSO party, I wasn't eager to mess around trying to debug it, so I just turned off the RIT and managed without it. I still had folks occasionally calling me noticeably off frequency for the rest of the evening. I still don't know if the RIT aggravated the situation or not, and I spend some time this afternoon looking through my Elecraft mail list archive for anyone else that may be experiencing anything similar, and turned up empty-handed. There are two things also to know: 1) I was using the latest N1MM+, but was not using it to transmit, i.e. I was using the DVR built-in to the K3 instead of function keys on N1MM+. In CW contests, I do the opposite, preferring to use the CW memories in N1MM+. 2) I have the RIT knob set to do fast tuning (on SSB that means 500 Hz/click) when the RIT/XIT are disengaged. One other observation: At no time did I see the transmit frequency on the K3 move. Only the displayed receive frequency moved when RIT was engaged. I'm baffled as to whether this is real or not, but this occurred after I installed the new KSYN3A boards (I have the sub-receiver) without a hitch. Maybe the guys calling me had their RIT turned on, and thus were calling me off frequency from where they spotted me. Ideas anyone? I do have the means to monitor my transmit output via a portable HF transceiver, but haven't tried that yet. I'm also running the latest non-Beta firmware in the K3. 73, -- Dave, N8SBE -------- Original Message -------- Subject: [Elecraft] KSYN3A_transmit_frequency_jumping_around?

As it turns out, you were one of the loudest stations and several times I just left my K3 tuned to you while doing stuff in the car. I don't recall hearing any kind of frequency jumping/sliding around from you. All totaled, I probably listened to you for the better part of an hour. Admittedly, a small sample, but there you go. As a general comment, many operators, even with today's newer transceivers, have difficulty tuning in stations. I can't say why... skill, age, familarity with their equipment etc., but I hear it a lot when operating from the Caribbean in a contest. 73 charlie, k1xx/m On 4/19/2015 2:54 PM, Dave New, N8SBE wrote: > Sorry for the blank first message.

For contest operation, nearly all RTTY operators use either N1MM Plus or WriteLog, both of which make it easy to use both software at the same time. For casual operation and DXing, I use WinWarbler, which is sort of a "wrapper" for MMTTY and 2Tone. We use more than one decoder because even the best of decoders (and these two are quite good) will sometimes fail to decode a signal while the other will. I use AFSK and VOX. Your computer should connect to the Line In and Line Out jacks of the K3. 73, Jim K9YC From steve at g4gxl.com Sun Apr 19 18:40:53 2015 From: steve at g4gxl.com (Steve, G4GXL) Date: Sun, 19 Apr 2015 23:40:53 +0100 Subject: [Elecraft] FDIM at Dayton - register now !

Also, compare 40M with no ATU enabled to 40M with the ATU enabled, using the same dummy load and wattmeter. Go over all of the KXATU tests and diagnostics for the three bands. Next: Assuming 40M is working with your ATU, try alternate antenna and counterpoise lengths. I saw somewhere using two counterpoise wires of 16 feet each and I do this. You might also add a 30 or 33 foot counterpoise to help on 40M. A rule-of-thumb is to avoid anything which is 1/2 wavelength or a multiple thereof for the antenna. Half-wavelength antennas are high impedance at the feedpoint; above the range of the ATU in the KX1. For example, 33 feet may work well on 40M, but is a half-wavelength on 20 and would have difficulty tuning on 20M. I've used 40-42 feet for my radiator with two 16 foot counterpoise radials. It seemed to avoid a half-wavelength on 30M (which would be 46.3 feet) and worked on three bands. These short (28 foot) wire antennas and single, short radials will work on the three bands and the short lengths make it easy to hang from a balcony, tree or a collapsible pole, but they are a minimum. The antenna will perform better than a helical or center-loaded whip, but it is pretty much a ground plane with a poor radial and antenna literature suggests that many radials are needed for efficiency in verticals over ground. Some time, I want to try more wire on my end-fed field antenna, possibly 80 to 100 feet with several 16 foot radials, or, a radial for each band. That would be more effective than 28 feet/1 radial. I'd also like to try a doublet of 60 to 88 feet; fed with a parallel feedline of made the same "stealth" wire as the antenna (no heavy ladder lines). The doublet would be more cumbersome (requiring one central support or else supports at each end). The antenna plus feeder length would be chosen to provide a relatively tame feedpoint impedance and reactance on the three bands; 40/30/20M. More research is needed on end- and center-fed (no coax) wire antenna lengths for the KX1 (and the KX3) I agree, leave the co-ax at home! 73 Jay W6CJ -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Pat Ring Sent: Sunday, April 19, 2015 15:09 To: elecraft at mailman.qth.net Subject: [Elecraft] KX1: requesting recommended wire antenna lengths advice Hello. I researched this, eh, pretty thoroughly, but I keep running into a little problem with the recommended lengths for direct-fed antennas. The KXATU guides recommend a 24'-28' radiator and a 1/8 wave ground/counterpoise, but I have seen 28' and 41' recommended as well (some with recommended radials and some without). The 24' wire tuned up fine on 20m and 30m, around 1.2:1, but I can't get an KX1ATU lower than about 8.9 SWR on 40. Am I missing something obvious, or should I continue to experiment? I've only tried that ATU about three times on 40M because that SWR seems pretty high to me and has to be tough on the kit. I am reluctant to continue to try anything in this range now. I don't really want to take coax on the road with me, and 20m and 30m are ok, but I would like to participate in the 4sQRP on 40m when I am on the road this week. I would appreciate your advice.

OTOH, such non-resonant antennas are sensitive as to how they are deployed. If you continue to have trouble on 40 meters, I would suggest a 33 ft. radiator with a 33 ft. radial. That should be close to resonance on 40 meters and provide a sufficiently low feedpoint impedance to the KXAT1. 73, Don W3FPR On 4/19/2015 6:08 PM, Pat Ring wrote: > Hello.

I've got a steady, S8, spur just about on the 30 m WSPR freq from the broadband company's stuff at the top of my tower, and WSPR still decoded some stations. So, tonight will be Test #1.

The feeder is twisted pair #22 teflon insulated wire (parallel feedline) 25 feet long. That feedline terminates into a balun which is switchable between a 1:1 and a 4:1 ratio (a smaller homebrew version of the Elecraft BL2). I carry a 25 foot length of coax to connect from the balun to the transceiver. That antenna loads and works well for 40 through 10 meters - I switch the balun from the 1:1 to the 4:1 position depending on the band in use and the best match. I also carry two additional lengths of #22 teflon insulated wire which I clip onto the ends of the radiator to extend the length if I want to operate on 80 meters. That is my portable antenna, and it works well for me. I prefer balanced antennas when I can use them. It is not 'backpack' eligible because of the 32 foot pole, but then I am not doing any backpacking these days. I can put my antenna up in several configurations. If I have a support for one end, I can set the antenna up as a dipole. If I only have the fiberglass pole, I support the center of the dipole at the top of the pole and use it as an inverted VEE (the most desirable and common configuration). In cases where I do not have much horizontal real estate to work with, I set it up as a vertical - the end of one radiator wire is tied to the pole and the other radiator wire is used as a 'radial' - 10 feet of it comes down the pole (the feedline is 10 feet above the ground), and the remainder of the 'radial' is hung on nearby shrubs and bushes in the best manner possible. So, three antennas in one - depending on the terrain and other available supports. 73, Don W3FPR On 4/19/2015 7:31 PM, J wrote: > I'd also like to try a doublet of 60 to 88 feet; fed with a parallel > feedline of made the same "stealth" wire as the antenna (no heavy ladder > lines).

I use a 33' MFJ telescopic fibreglass pole. (What holds your up? I use a 4 prong hand cultivator with a 3' shaft. Hold pole on shaft with a couple of bungee cords. I'd like to scrounge the arrangement you use for the homebrewed 4:1/1:1 balun.) Otherwise I opt for the Buddipole at 9 feet as a dipole or a vertical with two drooping radial wires. I have also used very frequently the 33' single wire vertical and a Electraft T1 tuner. (The T1 is sometimes cranky to get to tune.) Never thought about using the dual 22 guage teflon wire as a twisted pair balanced line! Just using a vertical wire I frequently use a single radial, the length varying depending on the band. ALWAYS a problem is 80-30 meters. Usually done with a pair of drooping radials and a vertical radiator consisting of 4 "Antenna arms" (88" total) and a single 9.5 foot telescopic whip above the antenna arms. One Buddipole loading coil at base of vertical /antenna arms combination tuned for resonance. In many instances the trees, etc. for Inverted V dipoles 2' fibreglass "driveway marker rods" 2 feet long. I will try the teflon twisted pair feeder. Never thought of that. I have some old 75 ohm receiving twin lead, good for that sort of thing, but it is too oxidized to consider it reliable in the field! I try to avoid the loading coils in the dipoles except for the higher bands. Although the Buddipole works well as a dipole at 9 feet up sometimes the vertical whip is better on 20 meters. As I said, ALWAYS a problem at 80-30 meters to play with verticals with whips. Good tips. All of that can be a big guess without the trusty MFJ analyzer! 73, Sandy Blaize W5TVW On 4/19/2015 6:58 PM, Don Wilhelm wrote: > My best field antenna consists of a 32 ft. heavy duty push-up > telescoping fiberglass pole which supports an inverted vee with > radiator legs 22 feet long (of #22 teflon insulated wire).

I usually can find some near vertical support post for the pole. At a campground, there are usually some vertical supports for a lightpole or a lantern hanging post. There is always a picnic table that can offer some support for the pole. Yes, I use bungy cords. If you want to add something to your go-kit, add a 4 foot PVC pipe that is cut at a 30 degree angle on one end. You can sink that into the soil by the angled end and use that for the pole support. I also carry some mason line that can be used as guys for the pole if no real supports are available. When deployed as an inverted VEE, the two radiator wires can also be used as guys, so the mason line is only needed for one (or 2 additional guys). In other words, do what you have to as dictated by the physical circumstances you are faced with. A little ingenuity will go a long way, use what is available. If you are planning a trip to the beach, a PVC pipe that can be driven into the sand to anchor the base of the pole and 3 or 4 tent pegs to secure the mason line guys will do the trick. In the forest of more primitive campgrounds, there are trees and shrubs to provide anchor points for the mast and any guy wires that are required. If you have a camper, that can provide a solid fastening for the base of the pole, but if using a tent, you may have to use the picnic table or other supports in the campground. Bungy cords will be a good addition to your portable gear. OTOH, if you are backpacking, you are not going to have the telescoping pole, so a weighted bag to throw over a tree limb (or a rock with mason line around it) will have to serve as your antenna launching device. It all depends on the circumstances you are faced with at the particular moment. I have graduated from backpacking in my older age, so I can take more gear along with me on my portable outings. 73, Don W3FPR On 4/19/2015 8:58 PM, Sandy wrote: > Don: > > I have done almost the same thing here on portable outings.

I had the cover off looking for any troubles. I disconnected the auto tuner and connected the dummy load to the ant out on the k2 and had full power out from there. While sliding the radio so that I could see inside a little better, the rig triggered tx and made a few dahs, go t real loud, then I heard what sounded like something short in the audio and smelled an odd odor.. this all happened within a second or two and it was too late. The entire radio shut down and I have no display, no relays click when I power on, no s meter etc. Checking inside, I do have power all through the power supply.. 8v and 5v to the MCU.. there, however, is where things go awry. No Tx or Rx. No power on pin 3, 6, 13, 19, and all other pins that should show 5v are either dead or showing only .1v or .2v I'm thinking the MCU? but I really can't figure out what caused it since nothing was touching bare wire when the catastrophe occured. Other symptoms include no voltage on U7 pins 1 and 2; U8 no voltage on pin 1, 9, or 11. I sure hope I can fix this. This is my favorite rig.

If so, it does sound like the MCU is gone. The best way to check that is to substitute a new one. However, some of the pins you measured are inputs to the MCU, so I can't be certain if that is the problem or not. It is unusual for the MCU to just go "Poof". Some more methodical measurements with the schematic in hand and a bit of logic would be helpful. Do you have the proper voltage at the power input pins of each IC for starters. 73, Don W3FPR On 4/19/2015 10:07 PM, w3att wrote: > K2 S/N 757 F/W 2.03d > > I was having some trouble with low power output through the K2 auto tuner.. > getting only about 1 watt or so into a dummy load. > > I had the cover off looking for any troubles.

It?s a 40-ft radiator with three 16-ft counterpoise wires. Depending on the circumstances and available supports I?ve deployed the radiator completely horizontally, as an inverted-L, inverted-V, inverted-U, a true vertical, and even in some indescribable shapes. I usually try to spread the counterpoise wires around the compass but they have also been hung from a balcony or even twisted together and wrapped around the base of the room walls as a single wire. The KX1?s internal ATU can usually give me a good match - better than 1.4:1 - on all three bands but there can be some situations where the match on one of the bands is worse. (Conditions found in portable setups can be very different from what you had during testing in the back yard!) The antenna is very small, lightweight, and strong. It?s easy to deploy using a slingshot or throwing bag. The only significant change that I have made from the original design is the use of 10-pound fishing line for the leader instead of the 30-pound line that WA3WSJ suggested. That way if it does get snagged in a tree the fishing line will break long before the steel antenna wire so I can always get my antenna back down. (I?ve only had snags like that three or four times over the years but I still feel bad about leaving some fishing line up in a tree. Does anyone have a suggestion for a good biodegradable line?) I?ve often wondered if it would be better with copper wire instead of the steel wire but I?ve never tried it. This antenna is not perfect - no antenna is! But I make contacts and have fun so that works for me.

Am I missing something obvious, or should I continue to >experiment? Pat : My experience is that you need a wire longer than 24 feet to get a decent match with the KXAT1 on 40m. Anything over about 12 feet long should match pretty well on 30m and 20m. Try 28 feet if you want to include 40m and perhaps consider a more extensive ground. For a ground system I use a 20 foot length of computer ribbon cable with 5 or 6 conductors. Unzip all but about the last 3 or 4 feet and then tape it so that it doesn?t unzip further. Strip all of the conductors at the intact end of the cable and attach them all to a banana plug. This makes routing the ground off a picnic table easy as it is one big flat ribbon but the individual unzipped wires can then be splayed out in different directions on the ground. I find that with more than about 5 or 6 conductors it starts to turn into a bit of a tangled mess. If I decide I want more radials then I use two of these. Note that the Pomona BNC to banana jack adaptors will allow two banana plugs to be connected to each terminal (i.e. 2 on the red and 2 on the black). If you want to use a shorter wire that will fit on a 20 foot fishing pole then try a 20 ft length of twin lead (I use the lightweight Radio Shack Indoor twinlead) with the leads at the top shorted together and soldered. Install banana plugs on both of the leads at the bottom. For 20m and 30m you can connect both banana plugs to the centre of the KX1 BNC, giving you a FAT 20 ft radiator. On 40m just disconnect one of the banana plugs and now you have a 40 foot radiator that is folded in half ? which is effectively a 20 foot linear loaded wire that will resonate a bit below the 40m band, but will match quite nicely on 40m. (Think of it as half of a 40 foot long folded doublet/dipole). I have used this configuration with a 20 foot fiberglass pole to make hundreds of 40m KX1 qsos and it works quite well and deploys quickly. Michael VE3WMB P.S. Trust me .. folding the wire back on itself does not result in signal cancellation. At worst your vertical will have a very slightly asymmetric omnidirectional radiation pattern.

Even when you do find one, or two, they tend to be rather short and skimpy. Even when trees are plentiful, they aren't always located conveniently. So, I more or less solved my "portable" problem with a good collapsible pole (mine is a 40 ft. Wonderpole), and a relatively simple device that attaches to my trailer hitch on my vehicle. This item slips into my hitch receiver, and provides a vertically oriented cylinder that is about 2+ inches in diameter and a little over 1 ft. long (tall). The Wonderpole just slips into the cylinder and rests on the ground at the bottom. It's very sturdy, and so is the Wonderpole. Anyway, with this setup I can be up and running almost anywhere in 15 minutes or less. I can hang an inverted vee or EFHW on the pole, or just use the pole as a vertical with wire running to the top. I know not everyone has a trailer hitch, but it's a shame if you don't! Alternatively, you can buy an attachment that does much the same thing as my trailer hitch device, but has an extended base plate which you just park one of your vehicle tires on top of. These "gadgets" are usually available at RV shows, etc. You may have to pay $40 or $50 for one, but in my view they are worth their weight in gold just to have the versatility/flexibility as to wherever you happen to be located. This is all NOT a backpack setup, obviously, but everything is easily transported. As for the KX1, you have to remember that the ATU in that rig is rather limited compared to other Elecraft tuners. It will do a good job in most situations, but nothing like what you can do with the ATU's in the K3 or KX3. So, be mindful of just how hard you are trying to make it work. Adding, or maybe even subtracting, a little length on the radiator may be all you have to do to make everything work. As others have cautioned, stay away from half wave lengths unless you are doing something "balanced", or have a matching network like for an EFHW. Also, since you are probably trying to "multi-band", I recommend balanced feed line. Cebik's 44' and 88' antennas are good choices, and I use them often. However, 80 meter results with the 88' version, and 40 meter results with the 44' version, are less than spectacular, and again, can be somewhat difficult to tune. If you are looking for something really portable as far as antennas go, check out what some of the SOTA guys are using--especially KT5X. Fred has portability down to a science.

It appears as if it is a regular input signal, i. e. it tunes normally. But it is still there even if the 2m antenna is disconnected or the input is shorted, so it seems to be internally generated. I have tried all the tricks I know such as moving of internal cables in the K3.

Has been working with perfection; no complaints, except I cannot operate QRP below 3 watts because that's the minimum RF required for the autocoupler.

I can't think of any reason this would be necessary except as a transition from the window line to a convenient coax output to the KX3. What would the KX3 prefer??

Probing around using a very small insulated pickup loop and a completely separate 2m receiver, the 144.416MHz signal is definitely not a spurious response of the K3's receiver. It is a real carrier and it's coming from the region of the DSP board(s) behind the front panel. The frequency seems to be completely independent of the K3's main tuning, band or mode, and on my particular K3 the frequency is 144.4162MHz (zero-beating on a GPS-locked receiver). The signal is quite loud with the probe loop held anywhere close to the DSP board along its whole length and on either side. The signal is louder when the loop is anywhere close to the main voltage regulator, the board interconnects or one of the mounting pillars; and when the probe is directly above or below U17 (EPM240TQFP100) it's S9+. All this suggests quite a strong discrete signal source that doesn't have sufficient local decoupling, so it is escaping via the supply rails and probably creating circulating currents in the groundplane and metalwork. The frequency is somehow being generated from the 14.7456MHz DSP clock crystal Y1 (as can be heard by probing very close to the board, which detunes the frequency). That isn't a precision oscillator, which probably accounts for any small differences in the reported frequency. However, there is no obvious harmonic relationship between 14.7456 and 144.416 (the factor between them is 9.79). That's as much probing between expensive circuit boards as I'm willing to risk! Over to Wayne... sorry, this is a fine way to begin the Monday morning after Visalia. 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of >Dave >Sent: 20 April 2015 16:13 >To: elecraft at mailman.qth.net >Subject: [Elecraft] Elecraft] K3 K144XV spurious signal on 144,414.1 > >Its also by far the loudest sprog I can hear on the 3 K3/K144XV combos I >have tested.

When transmitting, the spectrum display is (optionally) replaced by a display of the modulation envelope. One cool feature that I haven't seen elsewhere is that when the K3 is in CW mode, the envelope display optionally uses a split screen where the left half shows the CW rise and the right half the fall so you can see both edges at the same time. The simulated meter displays are at the bottom. The one on the left reads PEP and average power and the one on the right SWR. There is also a digital readout of PEP power and SWR. Either or both the modulation envelope and meter displays can be enabled and disabled via menu entries. You can also change the full-scale power for the meter and the ms/div for the modulation envelope display (the amplitude is auto-scaled).

We use the Si570 in the KSYN3A to obtain extremely low phase noise. But we still have to lock it to the 49.38-MHz reference. The synth stays locked to the reference within about +/- 0.2 Hz on all bands. This is a definite improvement over the original KSYN3. 73, Wayne On Apr 20, 2015, at 10:36 AM, "Fred Townsend" wrote: > Folks: > Reading the data sheet for the Si571 I see the worst case temperature > stability is +/- 61.5 ppm.

You can barely hear it if the antenna is connected and is far more apparent if the antenna is disconnected. I can mitigate or eliminate the noise by loosening the screws that hold the two halves together. I assembled the radio as a kit and it includes the antenna tuner, 2m module, and paddles. The radio otherwise works fine, but something seems to be off kilter when putting it together and tightening the screws. Does anyone have any suggestions on what to look at? I didn't see anything obvious. 73, Jim KA2RVO From edauer at law.du.edu Mon Apr 20 14:42:30 2015 From: edauer at law.du.edu (Dauer, Edward) Date: Mon, 20 Apr 2015 18:42:30 +0000 Subject: [Elecraft] K3 to K3/0 Mini Direct Connection In-Reply-To: Message-ID: Following up on the earlier post, in which a couple of others also expressed an interest: The quick answer is no, the K3 cannot be cabled directly to the K3/0-Mini acting as a control head.

Wish I had a K3/0 lying around, I could whip up something like this pretty easily :) As for the RS232 to TTL, that is really easy. The MAX232 chip and similar family chips do that with minimal parts. Usually just 4 small electrolytics and the chip itself. The caps form a charge pump to allow full +12/-12V RS-232 swings. There is another model, that works without the caps as well. See: https://www.sparkfun.com/tutorials/104 for a quick guide. You can buy MAX232 boards from that same site. You want a 5V model (for TTL) not a 3.3 volt one) If you have an old Icom CI-V to RS-232 interface on the shelf, you can reuse it as the level converter. The CI-V interface is TTL level on the 1/8 stereo mini jack side. (RS-232 of course on the other) The turn "ON" command is easily done through wiggling a pin the K3 ACC port, however the turn off sequence would take a slight bit of serial bits from a PIC or Arduino microcontroller to inject the "Turn K3 OFF" Macro sequence. There might be other ways, but I haven't dug in too deeply yet. You certainly don't want to just remove power from the K3 supply line as that doesn't give the K3 a chance to write the current settings/state to flash memory.

For the same reason, if you extend your 450 ohm line, you may create some impedances that could be difficult to match. A few sessions with the TLW software (see www.ARRL.org) will allow you to experiment if you know the impedance at the antenna feedpoint. A common mode choke at the end of the feedline will help with balance and keeping RF out of the KX3. 73, Don W3FPR On 4/20/2015 11:42 AM, stan levandowski wrote: > For several years, I've been using my multiband non-resonant 94' > doublet, fed with a short run of 450 ohm window line, to a remotely > mounted SG234 autocoupler and then a 25 foot run of 50 ohm coax to my > KX3. > > Has been working with perfection; no complaints, except I cannot > operate QRP below 3 watts because that's the minimum RF required for > the autocoupler. > > > Now, if I wanted to extend my 450 ohm line and connect it directly to > the KX3 and use the KX3's internal tuner, would there be any benefit > in a 1:1 isolation balun at the KX3? > > > I can't think of any reason this would be necessary except as a > transition from the window line to a convenient coax output to the KX3. > From cathrowinternational at hotmail.com Mon Apr 20 18:07:12 2015 From: cathrowinternational at hotmail.com (Jeff Cathrow) Date: Mon, 20 Apr 2015 17:07:12 -0500 Subject: [Elecraft] New P3 "meters" Message-ID: Very excited about the new P3 features soon to debut; one of the things I miss the most in my K3 is a good old-fashioned analog S-meter.

I suggest that you connect the wires directly to the rig / ATU and forget about the unun and coax. Because a 24/28 foot wire is non-resonant if you use coax to feed it you will incur additional loses because of the mismatch. No feed-line means no feed line losses. Michael VE3WMB P.S. Pat if you want a longer length wire, try 51 feet. It will load very well on 40m/20m, but it may require that you roll up a couple of feet to get below 2:1 SWR on 30m. I sometimes use this as an end-fed inverted vee or inverted-L worked against the previously mentioned ribbon cable ground. The KX1 ATU will match this. P.P.S. As a compromise I tried a 26 ft wire at one time and I was able to get a reasonable match on 40m, however I discovered that it is much more sensitive to how it is deployed, as compared to the 28 foot wire and in some configurations it was hard to get a decent match.

All very helpful. I thought the 24' length was going to be quite a compromise. Tried 28' but that didn't help much. Will try the solutions suggested. Michael, I was reading one of your blog posts describing your folded dipole and grounding solutions and dismissed it initially because I didn't want to carry a pole. Now I have a thought in mind on how to deploy without a squid or jackite pole and will look into that when I get back (I have some cat 5 cable I will untwist). Reluctantly packed some coax, unun, and long wire > (KX3 Helper) for the trip, but will look into other solutions when I return. I know this radio has been out for years, so I knew there would be a bunch of expertise here to help me. Thanks.

I am an antenna phreak and like to experiment and compare antenna options. I am on ten meters and have six yagis at different heights and combinations. 160 has six choices. On six meters I have four yagis in various combinations. (don't ask how many antennas I use on 144 MHz!) With the 6 dB LEDs on the K3, any comparison between antennas is pretty meaningless oftentimes. I found a neat software package that gives me a much more sensitive signal level meter, but it uses the serial port so it interferes with computer logging etc. Anything that will show fine detail in signal strength will be a Godsend for me. I loved my old analog S meter on my Ten Tec rigs. It was so valuable in such mundane things as tracking down power line noise with my very directional 144 MHz antenna. I could locate noise 3 miles away to almost the correct pole just from my shack! With the K3, I have lost that capability entirely as the chicklets do not change unless it sees a huge change in strength. Calling the power company to fix noise is a full time job here. Of course, for casual operating and contesting, the green chicklet display is fine. If Elecraft solves my S-meter problem, I will definitely become a true blue Kool-Aid drinker. Dave K1WHS ps.

It's a far better tool for evaluating the rf environment than an s-meter; analogue or not. In addition to having significantly greater amplitude resolution, you can simultaneously see the nature of the signal spectrum you're trying to evaluate. I do a lot of experimenting with receive-only antennas, and can't imagine trying to make evaluations without the P3. We have power line noise issues here too, and I use the K3/P3 along with my rotator and few yagis covering the range from 20m to 2m, to pinpoint the location, and then take the P3, a battery and small loop antenna in that direction until I find the source (which I always do). Then after half a dozen phone calls to the power company and 3 to 6 months, the issue is (usually) resolved. 73, Dale WA8SRA > Alan, > The only complaint that I have about my K3s is the darn S-meter > chicklet > display that is basically worthless to me as it does not show small > changes > in signal strength.

With the original synth, actual 1-Hz step size will be slightly larger on the highest bands due to quantization at the DDS. I don't have exact figures but if you have an extremely accurate external counter, you could determine actual step size on each band. The new synth provides much finer gradation -- typically 0.1 to 0.2 Hz -- on all bands. So a 1-Hz step will always be very close to 1 Hz. 73, Wayne N6KR On Apr 21, 2015, at 3:04 AM, Gary Gregory wrote: > Ok folks, its official.

Because the K3, due to it's IF frequency will not access all of the MARS frequencies, and also because the K3 is designed (on purpose) not to work on 27 Mhz at all. There are MARS frequency designators that fall within the 11 meter band. Since a lot of my MARS activities involve pactor message traffic I need to be able to access all MARS frequencies, including 27 Mhz.

I'm not how a rumor started that we were adding this in the short term. My apologies if we were misinterpreted. What *is* true is that we're going to have transmit power and SWR bar graph emulations available for the P3 when used in conjunction with an external RF sensor. There will also be a transmit envelope display (time domain, like an o'scope, in living color). Meanwhile, note that the P3 is already something of an S-meter on steroids. It reads out directly in dB, with 1-dB resolution, and gives you a history of signal strength (waterfall display) as well as signal strength for potentially dozens of signals simultaneously. 73, Wayne N6KR From k0az at centurytel.net Tue Apr 21 12:12:40 2015 From: k0az at centurytel.net (Mike Sanders) Date: Tue, 21 Apr 2015 11:12:40 -0500 Subject: [Elecraft] FS XV50 6M Transverter Message-ID: <002201d07c4d$fe95a390$fbc0eab0$@centurytel.net> My XV50 transverter is still for sale.

Now becoming an old fart, nostalgia is another important part of my daily life, too. Alan mentioned that he and the design team are still arguing about the display---and while I now expect that (as form generally follows function with all things Elecraft) it will be a bar-graph type for the power and SWR---I will continue to hold out hope for something akin to the curved Icom 7800 type. My fingers are tightly crossed and cable tied for good measure. Probably too much to ask but if the display had both types that could be switched that would make everyone happy.

Since it is a digital station, the solar also operates the P3, SignaLinkUSB and a MacBook Pro. The MacBook Pro alone draws almost 5A at 12V. Since there is no 12v power adapter available, it runs through a small 115v converter. I use a solar panel which can deliver about 6A at 12v in full, straight on, sunlight. It charges 3 AGM batteries which total to about 130-140 AH.

This probably isn't the answer he was looking for, and may be no answer at all---but LDG made/makes an analog S meter specifically for some of the Yaesu rigs (897/857). Wouldn't something like that be a possibility? Maybe even that unit itself, subject to some modification perhaps? I assume you could tap in at an appropriate point just like they do on the Yaesus. I still have my LDG S meter, although I sold the 897. It was kind of cool to see analog instead of LED bars. I don't know how accurate the thing is, but it was the kind of item you could make some comparisons between, audio vs. visual, and make whatever adjustment you felt was appropriate based on what you were hearing. If you put a signal generator on, I suspect you could calibrate the meter pretty accurately. I know this isn't as elegant as what folks probably want, but since Elecraft has indicated they aren't contemplating a mod like this, maybe it would be a work-around for those who feel particularly deprived.

Who successfully uses solar to operate KX3 QRP? What?s the system? I've not yet used solar with my KX3, but I've used it extensively with my K3/P3/KAT500. The most common way to use solar power is to charge batteries of suitable type and rating. For that, you need a charge regulator that sits between the panel and the battery. On Field Day, we set up a couple of panels next to the operating tent or trailer and run a twisted pair of #12 to the battery that's next to the rig. Long leads on the panel, short leads from battery to equipment. The best charge regulators are made by GV -- MPPT technology, which yields best efficiency, and lowest noise (they are VERY quiet). Charge regulator must match the panel voltage, the charge current rating, the battery voltage, and the battery type. One of the best battery types for our use is the LiFePO4 chemistry. Two good places to buy them. http://www.bioennopower.com/collections/12v-series-lifepo4-batteries http://www.batteryspace.com/128vlifepo4batterypacks.aspx Both companies provide intelligent technical support by email and by land line. Their prices are very good, and about the same for the same product. BatterySpace sells the RF-quiet GV charge controllers. Bioenno shows a much cheaper one, and I'll bet it's noisy. If you're going to pack the batteries, pay attention to capacity and weight. For example, the Bioenn BLF-1220W and BLF-1220TS are both rated 20A at 12V, but the 1220W weighs 5.5 # while the 1220TS is 7#, the 1220W costs $12 less ($193 vs. $205)! This is only one example -- both companies sell a lot of different batteries. 73, Jim K9YC From w3fpr at embarqmail.com Tue Apr 21 14:45:30 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Tue, 21 Apr 2015 14:45:30 -0400 Subject: [Elecraft] New P3 "meters" In-Reply-To: References: Message-ID: <55369ACA.9090903@embarqmail.com> There is already a high resolution "S-Meter" on the P3. It is the amplitude of the signal display. It can be set to read either S-Units or dBm, and it can be calibrated. For comparison measurements, such as between two or more antennas, the relative amplitude is sufficient and there is no real need for precise calibration. There is also a feature on the K3 that will do relative measurements for you - the Alternate VFO B display of AFV gives the true RMS voltage of the K3 AF (without regard for the AF Gain setting) and the dBV will indicate the relative deviation from that AFV setting. I know that will not satisfy those who are seeking something that is curved and looks more like the S-meter on boatanchor rigs, but there are software implementations for those who desire such a display. 73, Don W3FPR From k1whs at metrocast.net Tue Apr 21 15:01:02 2015 From: k1whs at metrocast.net (Dave Olean) Date: Tue, 21 Apr 2015 19:01:02 -0000 Subject: [Elecraft] New P3 "meters" References: <55358C6D.70608@elecraft.com> <003d01d07c47$d27bb7f0$777327d0$@net> Message-ID: <72A1BCF1D2A54094AAD7E678703C4D4D@t30ce0d73e1b34> Hello Jim, Yes that is the software that I have running on my laptop. It works really well. I tried the dBv feature on the K3 DISPLAY button, and that does not work well at all for rapidly varying signals. My brain can't process it all. A steady signal is much better, but there are very few steady signals on the bands when I want to check antenna levels. I can adjust the P3 for a limited scale of say 30 dB, so I can see changes there, but then there is the problem of signals going up out of sight on the screen. I tried it today on ten meters. Lacking a good analog meter, having a P3 seems to be the best choice now for what I need. Thanks for all the suggestions.

To summarize You can not operate reliably directly from a solar panel, you need a 12V battery ( buffer) The solar panel essentially charges the battery while the battery delivers a constant voltage current surges. You can not charge the batteries in the KX3 with 12V the KX3 will produce an error. You should have about 13.8V.

They do often have cursors which one can position which will display a numerical value of the curve at that position. Spectravue which accompanies the SDR-IQ has selectable resolution of the vertical scale from 0.01 to 10 dB per division. I use 0.2/DIV for making sun noise measurements with my 16-foot dish. The jitter in the white noise allows me to estimate level to 0.1 dB using that scale. 1-dB/DIV is perfectly reasonable for viewing radio signals. I usually set up 5-dB/DIV when observing eme signals (and you know they are weak!). For a typical S5 signal on 20m you will get very good resolution (assuming your local noise is lower than S5). I get S3 to 4 on HF noise floor, on average, so S5 is 12-dB over noise. S9+20 is 56-dB over noise. 1-dB/DIV will have the display off the top of the screen. If I didn't already have LP-Pan installed I would be interested in a P3. With addition of transmitter signal analysis that is a real plus!

Although the policy is not stated anywhere, the general Elecraft practice is to expedite repairs on factory assembled new products which are DOA. This is a reasonable question because each manufacturer or retailer has their own policies about how returns & repairs are handled in general vs how they are handled for defective merchandise. Re whether asking questions about Elecraft policies is a valid topic, the list guidelines clearly state: "6a. Please post your experiences....crazy ideas...complaints etc. (yes - we do want to hear them)." I wasn't even complaining, just asking a question, which I'm glad is now answered.

I do Elecraft repairs (but only on the K2, K1, KX1 and XV series transverters), and I can tell you that anything DOA will be handled under the warranty terms. Exactly how it is handled will depend on the product and the circumstances. However, you must obtain an RSA or RMA number from Elecraft so there is tracking of the warranty repair or replacement. In order to obtain that number, you must first contact support - use k3support at elecraft.com for email, or phone the office at 831-763-4211 and ask for support. The support staff initiates the RSA/RMA process and you need to wait until you receive shipping instructions and the RSA form. If you emailed k3support at elecraft.com yesterday (Monday) or over the weekend, understand that they have a weekend backlog of emails to sort through on Monday and sometimes lapping into Tuesday , so it may be that they did not get to yours yet. 73, Don W3FPR On 4/21/2015 5:27 PM, Joe Marler wrote: > My question is now answered.

And do not accuse -anyone- of being a troll or make snide comments. That is well outside of the list guidelines for respectful dialog. We certainly are here at Elecraft to answer questions like this too. If you don't receive a fast email response (they can take up to a work day if the load is heavy here (and a little more than that on Monday's when we are processing all of the weekend email) give us a call. (831-763-4211). Also take note of time zone and day differences (for international customers). We frequently see emails on Monday that were received here after close of business Friday, followed by a complaint that we hadn't replied on Saturday.. ;-) Our CS group should be able to give you a quick answer to most questions, especially when you have a suspected failure. They will work with you over the phone or via email to zero in on exactly whats happening. Frequently its not a h/w failure (we 100% test the boards and assembled products here), but rather a misunderstanding on how to set something up etc. If not, if its clear to us that its a specific defective board or module etc, we may also ship a replacement out to you. More complex issues of course will require a return for us to diagnose and fix. Eric elecraft.com And list moderator when I get the urge..

If so, please understand that the optimum frequency for that reference oscillator may be slightly different than exactly 4 MHz. It can be refined later. The K2 does not use that reference on a real time basis for the frequency readout. It only has to be accurate when running the CAL PLL and CAL FIL procedures. At this point of your alignment and calibration, just set the C22 MHz trimmer to mid-range. Don't worry about it until you have completed the K2 construction and are ready for the final frequency calibration. Then go to my webpage www.w3fpr.com article on K2 frequency calibration and follow the procedure given there. That should result in not only good frequency calibration of the K3 as well as properly aligned K2 filters. 73, Don W3FPR On 4/21/2015 7:45 PM, Kevin Hulina wrote: > For this alignment section, it mentions using a "calibrated external > frequency counter", or a ham/sw receiver, or later using WWV on-air. > Since I don't have a "calibrated external frequency counter" at home, > what are many people doing for this portion of the alignment and testing? > From WB4SON at gmail.com Tue Apr 21 20:08:03 2015 From: WB4SON at gmail.com (Bob) Date: Tue, 21 Apr 2015 20:08:03 -0400 Subject: [Elecraft] Feature Add for P3 -- DX Split Mode Message-ID: I wonder if it might be possible to add a DX Split Mode to the P3 (beyond the fixed or tracking mode)? I would envision this to maintain the current RX frequency close to the left or right side of the screen (depending on split UP or DOWN). The RX frequency would be shown in green above the RX spot, and the TX frequency would be shown in red on top line of the opposite side of the screen. The TX frequency would move along the display -- using the right or left arrow indicators if it is beyond the display limit. Should the user change the RX frequency, then the display would shift, but the RX frequency would continue to stay in the same spot near the right or left side of the screen. The span could be adjusted at any time, but it would not cause the RX frequency display to shift from its position on the screen -- it would allow for larger or narrower display of responding signals. The span tick marks would be scaled to the span but still be something logical so it would be somewhat easy to figure out +1 +2, +5, +10 splits. The traditional center frequency display would be removed. Perhaps the FixTrack could be changed to be Fixed/Tracking/SplitUp/SplitDown and you could step through the modes that way. Anyway, this is sort of how I run things today but I have to keep moving the span and reference frequency when I change things -- changing the span causes me to to back to square one. 73, Bob, WB4SON From k6dgw at foothill.net Tue Apr 21 20:11:00 2015 From: k6dgw at foothill.net (Fred Jensen) Date: Tue, 21 Apr 2015 17:11:00 -0700 Subject: [Elecraft] X-Dragon 20W Solar Panel In-Reply-To: <9010806D-AD70-46A9-AA6E-890C1262FC30@me.com> References: <10538249-B3E7-47F1-8784-968561A89C0C@me.com> <1429632304024-7601650.post@n2.nabble.com> <62E66F9E-0237-42FF-870D-F8491E881800@me.com> <003601d07c57$fa090b00$ee1b2100$@earthlink.net> <9010806D-AD70-46A9-AA6E-890C1262FC30@me.com> Message-ID: <5536E714.8040908@foothill.net> I do.

These guys (and ladies) are dead serious, and are not afraid to spend some money. Don't confuse them with the guy at the local swapmeet who saved the 50 cents on a bar of soap so that he could haggle with a seller to get a dollar mic for his half buck. It was obvious from who the vendors were - most of them hawking high-end products like amplifiers, antennas and the like - and what they didn't have on display. Even at the Yaesu and Icom booths, there was nary a thing that would appeal to the shack-on-the-belt members of the fraternity. Back in the late 90s, when US Tower was located in Visalia, they would have an open house and lunch for anyone from the convention who stopped by. It was not unusual for some of the visitors to pull out checkbooks or plastic for thousands of dollars worth of purchases. I'm sure that Eric and crew took lots of orders for the K-Line and KX3-Line products. 73 de Jim - AD6CW On 4/21/2015 4:54 PM, David Cole wrote: > Yeah right... Never going to happen...

I am not transmitting - not sure the K3 will actually do that, and at any rate I don't have an experimental license for that "band" and I'm way too old for the "Gated Community for the Ethically Challenged." It's not likely I will transmit there any time soon. Tonight's experiment: I'm going to catalog the NDB's [and other identifiable signals] I can hear with my headphones in CW and near-CW bandwidths using a different [much bigger but not-so-vertical] set of conductors in the air for the antenna. Before bed, I'll start WSPR, turn on spotting, and we'll see what appears when the sun comes up. So far on CW at roughly 30-35 WPM full QSK, with KPA500, the new synthesizer is living up to the claims. I no longer hear any artifacts in the keying, and when I record it on another receiver, it sounds totally clean.

If you wind your own, the big challenge is not in the winding (but remember that a straight wire through the core is one turn, and a full wrap around the core is 2 turns), but the challenge is in stripping and tinning the leads. I strongly recommend the 'solder blob' method - use an iron with a wide tip and a higher than normal temperature (800 degF). One of the common problems with K2 construction is poorly stripped and tinned toroid leads. 73, Don W3FPR On 4/21/2015 8:20 PM, Kevin Stover wrote: > Just sitting here thinking about my K2/100 and how many toroids there are to wind.

No not building a new one just sitting back reminiscing about building #4684. A couple of hours every night after work and weekends. The key for me was to stop at a logicak spot every night so it'd be easy to pick up the next night. As for stripping enamel off toroid wires I started out with the pool of soder method but soon came up with my own. I used a small propane torch to burn the stuff off followed by a few swipes of fine grit emeory cloth and finally a good thin tinning of solder. I'll have to dig my assembly manuals out and count them up. -- R.

Message-ID: <4B99EAC4058B4F01A96FD4F0334F3AED@TDYDell> Ken and all, While I agree that hams can haggle over 50 cents seemingly forever, isn't that more due to the "ritual" of bargain hunting? As often as not, someone someone "negotiating" like that doesn't really know exactly what they might do with what they are proposing to buy, and so they don't want to pay a lot for it. If something is really coveted, the price usually tends to get closer to reality. At the same time, sellers are often just trying to rid themselves of excess items, and don't really try that hard to get full value. Getting rid of something is often much more important that squeezing another dollar out of the purchaser. I think Don Wilhelm has it about right. Hams aren't truly "cheap" so much as they are "frugal", and sometimes to excess. For one thing, I think most hams have invested a lot more, probably, than they needed to, and maybe to the point where they may be stretching the budget! Ham gatherings like Visalia and Dayton are where you will see a buying frenzy that often boggles the mind! Where I think a lot of hams make their mistake is by "under-buying". They may opt for a somewhat lesser product, or a stripped down product, when it truth they really need a somewhat upgraded version (or a different item altogether) to really satisfy their needs. So, later they have to upgrade, and at an increased cost, or at least increased inconvenience. It's not that they couldn't really afford the upgrade at first, but they haven't really thought things through adequately. Cost/benefit isn't always easy to evaluate. The morale here is that, once you have committed yourself to spending several hundred dollars (if not thousands), don't focus too much on spending another relatively few dollars to make it really do what you need it to do! This may seem like a ridiculous metaphor, but consider the process of buying a bottle of wine in a restaurant. One bottle costs $10, and you don't know much about it. Another may cost $16, but you have a good idea it is decent quality. If you opt for the $10 bottle, and it turns out to be more like vinegar, have you saved $6, or have you wasted $10??? My dad, who could squeeze a nickel as well as anybody, would opt for the $16 bottle--every time! He always said the real decision is do you spend anything at all, but once you make that decision, you should make sure you get something of value in return, and not worry about a few more dollars. It's kind of the "penny wise and pound foolish" thing. I know I've wasted a lot of money buying things because they were "inexpensive", and later found that there was a very good reason for the low price!!!!

Make sure all of them are plugged in all the way. Since you swapped the synths, the problem is likely on the ends of the cables that do not go to the synths. You have probably checked and double checked the locations of all the cables against the diagram in the instructions, but I would do it again. The symptom suggests that they are not hooked up correctly. It might be worth checking the ends of the cables carefully to make sure they are OK. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 22 Apr 2015 14:07, Jim wrote: > Sometimes you wish you had left well alone! > > I installed the new KSYN3As this morning.

It is a general practice, at least amongst the US. 630M experimental ops, to report estimated ERP instead of actual TPO (transmitter output). With the low antenna efficiencies that come with this territory, that generally means most stations are running 100W or more TPO. The antenna here is a 67 ft vertical w/ 8x30ft top loading wires and about 22000 ft of radials covering approx 350x350ft area in an open field. The ground is damp most of the year. Last measured ground + coil loss was around 4.5 ohms, for an efficiency of approx. 16%. That is considered high, most efficiencies are in the < 5-8% range. Hope to see you guys again. The real fun will start back up mid to late fall and through winter when there are regular CW QSOs going on, incl. coast to coast (yes, at 10W ERP or less). Though, WG2XIQ in TX was good enough this morning (-4 SNR 2.5kHz BW) to complete a CW QSO, which we've had many over the course of summer. 73 Eric NO3M (WG2XJM) On 04/22/2015 07:17 AM, drewko wrote: > I set up WSPR last night on 474 KHz here from SNJ.

After talking to W6AIM about setting up the NCC-1 with the same Elecraft gear we both enjoy I decided to put a sequencer inline to protect everything for good measure. I will be running QRO most of the time as my antenna situation is minimal and the KPA500 invariably comes in handy when trying for DX. I know the delay upon keying the PTT line should be on the order of just a few milliseconds (4-6)---but what about the transmit delay for the K3 and or amp? Isn't there about 15 or more ms of hang time on those? Should the delay be the same for the K3 as the KPA or slightly different? I'll have the following hooked up to my DXE Time Variable Sequencer: one active DXE RPA preamp for one of the two noise receiving antennas, the NCC-1, K3 and KPA500. (Eventually I will probably add another DXE preamp for the other noise antenna so they are balanced but I happened across a good deal on ebay for one in the last week). I am particularly curious as to what I should set the delay for the K3 & KPA to (the delay is adjustable in 2 ms steps by DIP switches in the sequencer) as when I am transmitting I want to have the delay long enough to avoid any "trail" of RF getting into the receive end of things. Any help will be much appreciated! 73, Jeff, NH7RO From tom.ng3v at gmail.com Wed Apr 22 10:49:08 2015 From: tom.ng3v at gmail.com (Thomas Skinner) Date: Wed, 22 Apr 2015 10:49:08 -0400 Subject: [Elecraft] New K2 build.

Removing it weakens the overal housing and the "support" for the lead where it connects to the actual capacitor and will potentially allow moisture into the capacitor. It's in no way "excess".

Dave brings up a good point about Elecraft products. From the K2 at the beginning, it was possible to buy a very basic (I won't say stripped-down) radio and expand it as operational needs dictate and the budget allows. Maybe a ham couldn't afford a full-blown K3 with all of the options initially, but he could squeeze enough out of the budget to buy a K3/10. Added savings could be had by ordering the kit version. Eventually he could add the needed modules to finish the job. Try that with any of the "Big Three" manufacturers of ham gear. The new synth boards are a good example. With Yaecomwood, the newer version of the K3 would be the "K3-Plus," for example. 73 de Jim - AD6CW On 4/21/2015 10:51 PM, dyarnes wrote: > Ken and all, > Where I think a lot of hams make their mistake is by "under-buying". > They may opt for a somewhat lesser product, or a stripped down product, > when it truth they really need a somewhat upgraded version (or a > different item altogether) to really satisfy their needs.

In-Reply-To: References: <675754BE-3273-47A9-8CE5-1FA6AF40925A@gmail.com> Message-ID: So far, I've owned a KX1 and two loaded K2s built by others. One was from ebay, the others from members of this list. The ebay one was S/N 495 and went directly to Don to be sorted out, because I knew it wasn't up to date, and it was my first Elecraft product. That was about 10 years ago, I believe, and it is every bit as good as the more recent one I bought, S/N 6911. They sit side by side, 6911 mainly for QRP/CW, and 495 connected to a KPA100 w/ATU in an EC2 case, used mainly for digital modes. Both have been entirely trouble free. The KX1 was purchased from this list maybe 8 years ago. It was also trouble free from day one. I recently sold it as I rarely ever operate from the trail, and when I do, the K1 I built is better suited to my needs. So I wouldn't be so quick to write off the efforts of other builders. Elecraft has done an outstanding job of making kits that almost anyone can build and enjoy success. That success extends to succeeding owners of those rigs. The quality of assembly may vary to some extend, but nothing that can't be fixed by the next owner. A healthy used market stimulates the new market. Prospective new buyers are assured that when they want to get something else they won't have any problem selling their existing rig--something auto manufacturers have known for a very long time. I owned and operated my KX1 8 years for free thanks to the healthy used market in Elecraft products.

He says he can hear the internally generated 2m signals from the K3 if he places a short antenna on top of the K3 connected to his IC-706 on 2m. He hears a strong signal at 144.418 MHz as well as many weak and a few strong signals between 144 and 144.5 MHz. Interestingly he also says that if he uses an external antenna on either his IC-706 or his DB6NT 2m transverter which is in an enclosure and placed directly on top of the K3 he will not hear any of them. With undesired signals like these, one can either look for the source and try to quiet it, or one can shield the receiver to prevent it from hearing them. The latter actually seems to work in this case.

That makes sense from what I?m seeing here. The effect is greater at higher power settings although not proportionally higher as my set level increases. I?m just wondering if the amount of shift I?m seeing is normal. Here?s what I?m seeing: With my K2 operating into a zero SWR 80 watt (nominal) dummy, the observed increase both on the K2 display as well as on my computer monitored W2 wattmeter tends to be 1.5 watts or less over a ten second period. The initial increase happens quite quickly and then slows. It is difficult to confirm, as I don?t want to leave the rig in tune for an extended period, but it seems like the system stabilizes or at least increases very slowly once it passes the initial increase. Operating CW at 12-15 wpm into the dummy, the power output fluctuates but doesn?t exhibit a tendency to rise more than noted above, given a 50/50% sending/receiving behavior. My observations were made at 7.100 MHz with power settings at 2, 5 and 10 watts. The K2 was connected by short length coax leads through the 200 watt W2 Wattmeter Directional Coupler into a dummy consisting of a set of 4 series-parallel 50 ohm Caddock MP820 thick film non-inductive resistors mounted on a fan-cooled heatsink (nominal 80 watt rating) that shows zero SWR from 160 meters through 24 MHz and 1.1 SWR thereafter though 6 meters as measured with an MFJ 259B Antenna Analyzer. The resistors remain cool to the touch even after extensive testing. So, do I need to be concerned about the power increase behavior I?m seeing? I do wish to operate digital modes such as PSK31, Hellschreiber, and similar modes where the duty cycle is higher than casual CW or SSB phone. Assuming normal power level control in the K2, is there a power level setting recommended to protect the final in this type of operation? In the future, I plan to homebrew a linear amplifier to give me PEP output in the 80 to 100 watt range primarily for SSB. I was hoping not to have to create gain control back into the K2 from the amp as is done in the K2/100 setup. Any recommendations from those who run a homebrew linear?

I do not think you will have a problem with it in normal operation. Keep in mind that the K2 power control resets after a band change or a change in the requested power setting - the output starts out low and then increases to the requested setting. That is done purposefully to prevent overshoot. The initial increase you see is likely a result of starting out at a lower power level and then increasing. It takes a couple dit times to come up to the requested power. I have no suggestions on the homebrew amplifier other than to say that if you include a closed loop power control as is done in the KPA100, you may find it easier to simply add the real KPA100 - the KPA100 wattmeter circuit is scaled for high power operation and eliminates the scaling for low power operation - all that is controlled by the KPA100 firmware. I doubt your homebrew amplifier can achieve that level of integration with the K2 at a price less than the KPA100. 73, Don W3FPR On 4/23/2015 8:43 PM, George Kuehn wrote: > I know from the forum that a K2 will show a power increase over a given setting if left in tune for an extended time as a consequence of the final transistors heating up.

I currently have an AL-82, and am getting tired of all the band switching etc. My only real issue with the KPA-500 is the output power of only 500 watts. Just how much of a hit will I take by going from 1500 watts to 500 watts... I chase DX, via RTTY and CW mostly, and some SSB. I get DB, and realize that I will take a roughly a 5 db loss in signal, which is one S-unit... Will the KPA-500 take key down for 10 or more minutes at full power?? Is there anyone on here that has gone from 1500 to 500 watts, and if so, can you tell me a bit about it? How does the LPA-500 operate on MARS frequencies?

(we're splitting hz here, hi) serious recommendation: next FMT do a K3 party, K3 owners enter & display results. A K3 with SpecLab - new KSYN3 or old - on 40/80 should be within one hz on digital modes such as RTTY - when the KSYN3a new board makes correction or "step change" wonder how that affects the decoders someone would have to test that in lab, same test done to test software (like 2tone) old board then new board using same recording & decoder settings.... 73 Robert W5AJ SMIEEE -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Eric Swartz - WA6HHQ, Elecraft Sent: Thursday, April 23, 2015 7:41 PM To: dave at nk7z.net Cc: Elecraft Reflector Subject: Re: [Elecraft] New Synth Question...

Of course, the KXPA100 integrates very nicely with the KX3. In other words, the K2 wit KPA100 works like a 100 watt class transceiver. The KX3 with the KXPA100 operates like a 100 watt transceiver. The KXPA100 with any QRP transceiver driving it (K2 included) operates like a transceiver followed by an RF sensed 100 watt amplifier. 73, Don W3FPR On 4/23/2015 10:55 PM, Phil Wheeler wrote: > Don, > > Since I have the KPA/KAT100 I've not really given it much thought, but > how about using a KXPA100 with the K2?

David, I think you will enjoy using the KPA500, although I?m a bit biased. The KPA will run just fine from 1.6 to 54 MHz, with the exception of the CB Lockout area from 26 to 28 MHz, which is FCC-mandated for amplifiers in the US. I can?t answer your question about going from 1500 to 500 watts (Like Fred, I run mine at 600). I can tell you that with the amplifier I am definitely heard in contests, which is where I do most of my operating. It makes a huge difference. My station is on a city lot in San Jose, which means small antennas. As I said the difference between 100 and 600 watts is that at 600 I feel like I am heard. I am sure you will hear from others on the power comparison and the KPA500 operation as well. - Jack Brindle, W6FB Elecraft Engineering (like I said, I?m a bit biased?) > On Apr 23, 2015, at 9:42 PM, Fred Jensen wrote: > > On 4/23/2015 7:34 PM, David Cole wrote: > >> My only real issue with the KPA-500 is the output power of only 500 >> watts.

If the amp were a 1 KW amp this would be a shoe in, but 500 watts as the most power possible worries me for contests, and DX... However having everything run from the K3 would be really nice, I am just not sure it is worth the loss of 1000 watts for ease of operation. That is where the feedback is helping me. I will do a redux of what everyone has sent in a few days, sanitizing the names off of the redux of course.

Well, there's 27 dB between the ears, so it's capable of making 100 w extremely pesky, 5 watts actually work, and in the hands of a total LID, render 1500 watts at a fine station useless. Have seen all of the above and everything in between, the 27 dB is fairly accurate. How come accurate? Because a fine QRP op actually CAN beat out a hopeless LID at 1500 watts with equivalent antennas. That's 25 dB. Need to add a couple extra dB to 25 because you don't know how far down in the hole a hopeless LID really is. LID probably needs a couple extra dB to be able to work anyone at all and get back up to zero. 27 dB between the ears. As to Fred's skills? Come on. At worst he's mid-range for NCCC, and that for sure is nothing to dismiss. He's just trying to sneak in a little rope-a-dope for the next contest, get you off your guard, beat you in the pile when you're not expecting it. 73, Guy.

Unless you're doing a lot of contesting/Dxing on 160, you'll probably not miss the extra power. I know every S-unit helps, but unless you're running an AL1500, LK800 or something bigger and can produce really serious power- the kind that can deliver 2 or 3 extra S-units- the drop from the legal limit to 700 watts isn't going to prevent you from working anything you can hear, especially if you've got decent antennas, at least from my experience. 73, Scott, N9AA On 4/24/15 1:35 AM, David Cole wrote: > Hi Jack, > Thank you for that input!

I own three, each bought used for less than the cost of a new KPA500. I chatted with the designer, K4XU, at Visalia this past weekend). They're very good quality, not automatic anything, easy to repair because all the semiconductors are discrete and easy to find. I'm a very competitive contester, so if I'm competing high power, I want that 4 dB. I also work QRP in some DX contests, with about 150 countries worked, about 120 confirmed in LOTW. My "most of the time" setup is a KPA500 replacing the Titan. I turn on the Titan for difficult pileups. 4 dB is significant when conditions are marginal -- for example, the other guy has bad noise. The KPA500 is really a 600W amp, and you can run it that way in keydown modes like RTTY and JT65, except on 6M, where I get about 550W. I love it because it is instant on, has the 6M capability, and is pretty much automatic everything. A dit or a tap on the mic does bandswitching for both it and the KAT500. Its also a very clean amp (and so is the Titan). See k9yc.com/FTDX5000_Report.pdf and k9yc.com/P3_Spectrum_Measurements.pdf Dunno about operation on MARS. Ask Elecraft. The KPA500 is a winner. 73, Jim K9YC On Thu,4/23/2015 7:34 PM, David Cole wrote: > I am considering a KPA-500...

Adding an Amplifier Keying Circuit to the K2 is necessary and quite easy. Take a look at http://www.mmccs.com/mmarc/n0ss/index_k2.html for a good amp T-R Keying circuit. Note that this is the preserved website of Tom Hammond N0SS (SK). The kits mentioned are *not* available, but the circuit is easy enough to wire on perfboard - Tom provided the layout.

A little bit of antenna switching and you can have a choice between 2 amps. As an adjunct to a legal limit amp the KPA500 is wonderful. While the big amp is warming up you can be working stations. For a quick band change to work a spotted station you can quickly work him and get back to your previous band. I have used my KPA500 working heavy duty contest RTTY at 500 watts. The cooling is perfect. If you're running stations in a continuous stream the fan speed will ramp up to 5 and then periodically hit top speed (6). When in speed 6 it will cool the amp quickly back to the speed 5 level. The only problem I see with this is fan noise. Speed 5 is loud. Speed 6 is really loud. Casual RTTY, or search and pounce contest RTTY, even at 600 watts probably won't push the fan above speed 4. Speed 4 is relatively quiet. 73, Mike K2MK David Cole wrote > Hi all, > > I am considering a KPA-500...

Obviously not a pile-up buster signal, but I think we sometimes loose track of just how much or how little power is actually required to communicate. That said, in my opinion, if you're gonna run an amp, go for max if you have the room, and/or the budget.

Message-ID: <002901d07e90$e30217e0$a90647a0$@windstream.net> With apologizes to Wayne and Eric and with full understanding of this reflector rules, I am disgusted enough with Guy's below post that I HAVE to respond. Even if Guy's below post is 'tongue in cheek' it sure highlights Guy's lack of thinking by posting it. I have been a CW operator for a little over 62 years and I have never run QRP simply because I don't want to...my prerogative as an amateur. To me, a QRP operator ignorantly think it is 'cool' to brag about the contacts they make, not realizing it is not their station capability that is making a QSO but rather the person on the other end, who has the intelligence and station capability to dig the QRP signal out of the QRN and ORM that really makes the contact. Notwithstanding the above, Guy has found the intestinal fortitude to label me as a 'hopeless LID at 1500 watts' just because in MY HOBBY I prefer to have my K3 drive my Alpha 9500 to its full 1500 watt output into my 16 element yagi at 80', IF I SO CHOOSE! Heaven only knows why Guy would want to post something that labels his own intelligence! NONE of us has the right to categorize others only because their participation in our hobby is different from their own. 73, Tom - W4BQF [*] **************************************************************************** ****************** Well, there's 27 dB between the ears, so it's capable of making 100 w extremely pesky, 5 watts actually work, and in the hands of a total LID, render 1500 watts at a fine station useless. Have seen all of the above and everything in between, the 27 dB is fairly accurate. How come accurate? Because a fine QRP op actually CAN beat out a hopeless LID at 1500 watts with equivalent antennas. That's 25 dB. Need to add a couple extra dB to 25 because you don't know how far down in the hole a hopeless LID really is. LID probably needs a couple extra dB to be able to work anyone at all and get back up to zero. 27 dB between the ears. As to Fred's skills? Come on. At worst he's mid-range for NCCC, and that for sure is nothing to dismiss. He's just trying to sneak in a little rope-a-dope for the next contest, get you off your guard, beat you in the pile when you're not expecting it. 73, Guy. ______________________________________________________________ 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 aldermant at windstream.net From mzilmer at roadrunner.com Fri Apr 24 09:24:46 2015 From: mzilmer at roadrunner.com (Matt Zilmer) Date: Fri, 24 Apr 2015 06:24:46 -0700 Subject: [Elecraft] [KX3] Lists of memories In-Reply-To: References: Message-ID: For the general purpose memories, I allocate five to each band: CW: around the top of the Extra segment for VFO A, and VFO B on the CW QRP watering hole for the band.

This doesn't work on all bands. For example 30m doesn't offer SSB operation. Tailor the schema to suit the band (lots of CW and Data A on 30m). For 60m, each memory is set to the SSB suppressed carrier freq (VFO A), and VFO B is set to the CW center frequency. This layout uses up 75 to 80 memories. I used a lot of the rest for MARS and SWL frequencies, WWV and CHU. Reserve five memories for test frequencies (49.38 MHz for example).

I have both a KPA-500 and a 2000A mounted on a shelf in my basement, about 3' below my feet in the shack. With one switch next to a K3 I can select which amp. Almost all of the time I use the KPA-500. It takes care of my needs especially on the upper bands. Sometimes on 80 and 160M if signals are marginal, there does seem to be a difference. If I find something or see something called out that I "need" on the low bands and they have a Q5 signal I just use the KPA500 to work them. If the signal is marginal I turn on the 2000A. I may get lucky with the KPA500. But many times as soon as I switch over to the 2000A I work the station. A few months ago I ran a test on 75M SSB comparing the KPA500 to the 2000A. I worked a couple dozen Europeans. Those that had a good signal on my end seemed to hear little difference on their end hearing me with either amp. With stations that were quite weak they could tell the difference when I switched amps. They said my signal went from tough copy to readable. By the way it is nice having a back-up amp. You never know........ Now if we only had the KPA-1500 I would need only one amp. :-) 73, N2TK, Tony -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of David Cole Sent: Thursday, April 23, 2015 10:35 PM To: elecraft at mailman.qth.net Subject: [Elecraft] Considering a KPA-500 Hi all, I am considering a KPA-500...

W3OU Steve -----Original Message----- From: Chester Alderman To: 'Elecraft Reflector' Sent: Fri, Apr 24, 2015 9:21 am Subject: Re: [Elecraft] Considering a KPA-500 - WAY off topic! With apologizes to Wayne and Eric and with full understanding of this reflector rules, I am disgusted enough with Guy's below post that I HAVE to respond. Even if Guy's below post is 'tongue in cheek' it sure highlights Guy's lack of thinking by posting it. I have been a CW operator for a little over 62 years and I have never run QRP simply because I don't want to...my prerogative as an amateur. To me, a QRP operator ignorantly think it is 'cool' to brag about the contacts they make, not realizing it is not their station capability that is making a QSO but rather the person on the other end, who has the intelligence and station capability to dig the QRP signal out of the QRN and ORM that really makes the contact. Notwithstanding the above, Guy has found the intestinal fortitude to label me as a 'hopeless LID at 1500 watts' just because in MY HOBBY I prefer to have my K3 drive my Alpha 9500 to its full 1500 watt output into my 16 element yagi at 80', IF I SO CHOOSE! Heaven only knows why Guy would want to post something that labels his own intelligence! NONE of us has the right to categorize others only because their participation in our hobby is different from their own. 73, Tom - W4BQF [*] **************************************************************************** ****************** Well, there's 27 dB between the ears, so it's capable of making 100 w extremely pesky, 5 watts actually work, and in the hands of a total LID, render 1500 watts at a fine station useless. Have seen all of the above and everything in between, the 27 dB is fairly accurate. How come accurate? Because a fine QRP op actually CAN beat out a hopeless LID at 1500 watts with equivalent antennas. That's 25 dB. Need to add a couple extra dB to 25 because you don't know how far down in the hole a hopeless LID really is. LID probably needs a couple extra dB to be able to work anyone at all and get back up to zero. 27 dB between the ears. As to Fred's skills? Come on. At worst he's mid-range for NCCC, and that for sure is nothing to dismiss. He's just trying to sneak in a little rope-a-dope for the next contest, get you off your guard, beat you in the pile when you're not expecting it. 73, Guy. ______________________________________________________________ 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 aldermant at windstream.net ______________________________________________________________ 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 sfbonk at aol.com From bill at wjschmidt.com Fri Apr 24 10:03:09 2015 From: bill at wjschmidt.com (Dr. William J.

I have never run over 700w in my 55 yr.s of haming and never thought I needed twice the power output.I run mine at 500w. On 30m I have it set at 200w. I don't have big antennas. I use a 3 el tribander, several homebrew 2 el WARC yagis, a Moxon on 30m & a Hytower. None are over 55' high. I am primarly a DXer but do contest a bit. My experience is just what it is. No reams of data or tech. theories. Being in the middle of the US I would think I'm average. I have a pretty gud DXCC total of 360 confirmed & 9xDXCC and just 5 short of DXCC on 6m. It works flawlessly with my K3 & KAT500.I'm no tech. guy for sure but everything is so straight forward even I can use it. I think one of the best advantages of the K line for a DXer is the speed to bring everything up & going in mere seconds. I see something to chase on the cluster & in 15 seconds I'm there ready to go with 500w. If I ran a tube amp with warm up time I'd be hearing a bunch on Elecraft guys calling as I waited for the warm up light to go out. Working rare DX is timing a lot of the time. I want to be in faster not later. I wouldn't have nearly the DX on 6m without the KPA. Again just my experience.

I run QRP during those DX contests whose rules are so tilted to the east coast that anyone living west of Detroit isn't in the game. It's a form of sticking my finger in the eye of those who continue to keep the rules in their favor. If they want a point from me, they have to work for it. 73, Jim K9YC From wes at triconet.org Fri Apr 24 10:33:18 2015 From: wes at triconet.org (Wes (N7WS)) Date: Fri, 24 Apr 2015 07:33:18 -0700 Subject: [Elecraft] Considering a KPA-500 In-Reply-To: <1429879746.7395.83.camel@nostromo.nk7z> References: <1429842878.7395.53.camel@nostromo.nk7z> <1429879746.7395.83.camel@nostromo.nk7z> Message-ID: <553A542E.8070202@triconet.org> I seem to have missed the original post. My 2-cents: I used a Drake L-4B (2 X 3-500Z) for years. It worked fine, was robust, instant-on and would tune the WARC bands and was a pretty good antenna tuner as well. What it didn't do was cover 160-meters. I don't contest, but am an avid DXer, albeit one with a fairly modest station antenna wise. Since I'm up in years and still three away from the top of the DXCC Honor Roll, with no prospect of ever getting there, (except for VK0 later this year and ARRL coming to their senses and deleting Mt. Athos) I decided that I would chase (HF) 9-band DXCC. Thus I needed something that covers 160. I considered another tube amp but most of interest have a warm up time. After running an 8877 on two-meter EME, years ago I remember the seeming interminable waiting time and didn't want to go through that again. After a whole lot of agony and consideration of the alternatives, I rationalized that I could make up for the drop in power with antenna and transmission line improvements. In my case this is possible, if you're already there, then the power drop might be a deal breaker. So, I have a new KPA500 and KAT500. Against all of my principles, I actually bought a tri-band beam to replace the HB 20-meter monobander and wire dipoles. I have some other antennas in work and 7/8" Heliax replaced the RG8. Hopefully, the KAT500 is a stopgap and can be removed later. So I'm looking for fractions of a dB here and there to add up to the power difference. In addition, the convenience factor is wonderful.

This will NOT help you in any way, but I'm offering it up merely as a point of humor, because I know some of you can identify with it and get a chuckle. I upgraded from a Johnson Thunderbolt to the KPA and I love it. I may have lost a few watts, but not very much. I don't push my KPA at all, but love it. The lack of warm up time and lack of having to tune it make up for about 6 db of effort. Of course, the KAT has to be used on some of the bands that don't have specific antennas. I've got QSK at my fingertips and instant band change, with no warm up at all. I love it, and so does my TS-590. No, I don't have a K3 or K anything else.

The responders also commented on the use of current technology smart linear amps that auto-switch bands and feed ALC or power output signals back to the exciter. That is great, although the convenience comes at a price that is justifiable, but nevertheless attention getting. About 35 years ago I managed WAS from Florida running 2 watts or less CW from homebrew transmitters and mostly wire antennas. Once I climbed that hill, I decided I wanted to go QRO to allow more comfortable ragchewing. So, I built an amp with a pair of 6146B tubes in parallel and drove the grids with my little qrp transmitters. This meant manual input and tank bandswitching, not to mention re-dipping the final each time I changed bands. The only non-junkbox and fleamarket parts in that amp were the tubes. That was fun in building and exciting every time I made a contact. So, I think the new linear for my K2 will be either a push-pull pair of switching FET's or a single grounded grid 811A. The latter will allow me to run 10 watts or so into the tube while the solid state approach will require either a low level of drive or some amount of attenuation. Given my background, manual bandswitching and tuning won't be a big deal and probably more fun than just plugging stuff together. All is according to what you're used to, I guess.

It would sure make my day. I used to have a very competitive DX station back in ILL and busted my hump to get every 1/2 db improvement, 1db opens a whole new world of signals out of the noise. Proven fact and QST articles were written about it years ago. Look up station design for DX in the QST archives. When the DX station is in a third world country with a S5 to S9 noise level and your pumping out a great 500w and your signal is S5, you are out of luck, the guy running 1500 has a good chance, as his signal will be over the noise level. Now consider that 1000 of your buddies are also running 1500 and are all say S9.. operator skill and luck play a big part of getting through, but if your station is optimized for every DB you may have a better antenna, less loss feedline, etc etc and be 3DB better than the others calling, your chances being a good operator are now in the top 10 percent. Depends on how competitive you are and what your goals are, Is 500 enough? yes to talk to your buddies a few states away, or contest in SS or FD etc. but its not near enough if you want to work em all. And thats my goal to work em all, Did that from ILL and currently at 333 countries with just a zepp antenna from KH6, and no 500 watts will not get it done. Operator is a major key, but DB in the operators hands is a tool you cannot afford to give up. 73 Merv K9FD/KH6 > Hi Brian, > Thank you for that info, especially from a DX station!

Obviously, if 500 watts is good, then 1000 watts, or 1500 watts, must be better! The question is "how much"? And at what cost? Add to that, "what are the downsides? You can compute what you are leaving on the table (in Db and/or S units), but it's an entirely different matter to determine whether you will or won't be heard with just the lesser amount of power. At 500 watts I'm picking up something over an "S unit" from my 100 watt barefoot power. I'm leaving something less than an S unit on the table by not running 1500 watts. For me, the extra S unit plus has been rather dramatic. For whatever reason, and considering my modest antenna situation, I seem to be "noticed" a lot more often, and have to repeat calls a lot less. It has gotten me a bunch closer to being able to say with confidence "if I can hear them, I can work them"! What you may want to do is run a test with someone who can vary his power widely so that you can hear the difference yourself. That may make up your mind for you. I suggest doing it at a level where 100 watts is readable with slight difficulty, then go up from there. I think you will find that the jump from 100 to 500 watts or so makes the biggest difference, and there are diminishing returns from there. In my view, the cost and inconvenience of going to even higher power is a big hurdle. I run my KPA500 on a 120 volt line, and it works just fine! If I go to 1 KW or higher, I need 220 volts! I don't have that in my shack. I can carry my KPA500 with 1 hand--easily! With my KPA500, and the companion KAT500, one or two "dits" and I'm tuned! Band changing is a snap! The amp is VERY quiet! As soon as I turn it on, it is ready to go! Even traveling with this amp is not out of the question. If I can't hear a station (which often is the case!), I can't work them. More power isn't going to change that. Only a better antenna will improve that problem. At 100 watts I was often questionable, but at 500 watts I'm substantially more readable at the other end, and usually enough to make the contact--and with Q5 results. In truth, I am probably benefitting from the other station's better antenna. Anyway, the only way I am apt to make significant improvements from my current level is to improve my antenna, not increase my power! Apparently, based on other comments, I could run the KPA500 up to nearly 700 watts. I don't do that. I just don't see the benefit of pushing the amp. Maybe the amp can take that without straining, but I don't want to chance it. another 100 to 200 watts seems almost meaningless. Contesters and DXers probably won't agree! If I ever get the urge to go to higher power, it will probably be to close to 1500 watts--but I doubt that will ever happen. Going to 1 KW is only 3 Db, and that just doesn't sound like enough vs. the problems I would be creating. Lastly, if anything ever happens to my KPA500, I have Elecraft to turn to. That is huge! I cannot put a price, or a value, on the peace of mind that gives me! With respect to amps, the KPA500 may be something of a compromise, but I think it is one of the smartest things Elecraft ever did! Notwithstanding all of this, if you are a die hard contester, or DXer, I strongly suspect the siren call of 1500 watts will get you --sooner or later.

Most of the time on 14.100, 4U1UN in NYC is readable here on the western frontier at all four power levels, although the 100 mW level isn't likely to be a pile-up buster. :-) The striking thing for me at least is that the apparent difference between 100 and 10 W [10 dB], while noticeable, really isn't all that great. I doubt I could pick out a 4 or maybe even 5 dB difference in most cases. I'm firmly convinced that operator skill is the largest factor by a huge margin. NAQP's are 100 W max. Compare my NAQP CW scores [www.nccc.cc] with the scores of the "masters" like K6XX, K9YC, or most anyone operating at N6RO, W7RN, N0NI, or W9RE. They're at least 20-25 "dB" better than I am. As far as DXing goes, my CQP buddy Larry, W4UAT, is at the top of the honor roll [5B] from a city lot in Livermore CA. I might get to 200 mixed if I ever got around to sending my cards in. The difference? -- I've watched him work DX, he runs circles around me. If I was really serious about DX, and I had to choose 100W + P3 vs 1500W and no P3, I'd take the 100 W + P3 in a heartbeat. I originally bought mine as a "toy" ... today, it's really all I watch if I'm in a pile-up or contest. And, contrary to at least one opinion, this is not "rope-a-dope" and I'm not sandbagging for the next contest ... I'm just not in the same league as those who win. Now, I did take "1st in W6" in a JIDX CW a few years ago. This could be accurately restated as "Next to Last in W6" too. :-)) 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 4/24/2015 10:55 AM, dyarnes wrote: > What you may want to do is run a test with someone who can vary his > power widely so that you can hear the difference yourself.

I agree. Guy didn't seem to me to be calling out any one individual in particular. What he said could be boiled down to "skill and experience beat higher power." Higher power does no good if the operator's fist is so bad, for example, that many others choose not to work him.

On CW I notice no issues. There have been a couple of times on SSB when I wished I had the 1500W but I eventually got thru. I'm working on DXCC for 160m and wonder if this will be an issue but so far if I can hear them I can work them (RX is only my inverted L). We'll see when I put up my short vertical array this summer (Hi-Z). This is only anecdotal evidence and may not have really been an issue. The K3, KPA500, KAT500 is essentially a 500w transceiver and works flawlessly for me. Mike KD8RQE In a message dated 4/23/2015 10:36:12 P.M.

REPLY: If you are into that price range, you might consider the ACOM 2000A which I consider the best amp on the market. Unlike the others mentioned it is 1500 watts, no duty cycle limit. It is tube type. I've had Alpha, Command, ICOM, a superb homebrew and others and the ACOM beats them all. Opinions will vary of course, but if I could have only one amp it would be a 2000A. 73, Bill W6WRT From mike.harris at horizon.co.fk Fri Apr 24 19:18:45 2015 From: mike.harris at horizon.co.fk (Mike Harris) Date: Fri, 24 Apr 2015 20:18:45 -0300 Subject: [Elecraft] Considering a KPA-500 In-Reply-To: <20150424155017.C4AD56BB@dm0219.mta.everyone.net> References: <20150424155017.C4AD56BB@dm0219.mta.everyone.net> Message-ID: <553ACF55.4080106@horizon.co.fk> They seem to be also offering a rather smart looking power combiner for any pair of their amp range.

Use the RED TRS (tip, ring, sleeve) mini-plug (or any similarly wired cable) and plug one end (the straight plug is my preference) into the SPKR output of the SignaLink device, and the other end (right angle mini-plug) into EARPHONE plug on the KX3 ? this is receive line. For the transmit line, you may have to home build, but it is easy as pie. In my case, I have an RJ-76 out of the SignaLink device into an adapter that connects to a right angle TRS mini-plug which plugs into the KX3 MIC plug ? this is the transmit line. I prefer using the SignaLink device because it does a wonderful job of isolating the KX3 from the Mac Mini (I think that?s important), and it regulates input and output levels really well. I do place a cheap external speaker on the SignaLink box, AUX output, so I can simply hear the digi-data back and forth in the background at a really low level. Happy to provide any guidance off list including photos, etc. The home brew transmit cable cost six-bucks, a modified MIC cable.

They work great together. To make it work, you need to use software like Fldigi and make sure that you point the software to the external CODC, both input and output. Run the headphones out of the KX3 to the speaker input on the Signalink and the audio out of the Signalink to the mic input of the KX3. VOX is not needed as the Signalink will key the KX3, if you have the correct cable and have set the internal jumpers correctly. Use the knobs on the Signalink and the volume control and mic gain on the KX3 to set your levels properly. A useful hint is to leave the headphones connected to the Signalink and use the aux to connect to an external powered speaker. That way you will only need to swap the mic for the Signalink cable when going from digital to phone or back. 73, Barry K3NDM To: "elecraft" Sent: Friday, April 24, 2015 8:19:41 PM Subject: [Elecraft] KX3 And SignaLink USB I read five months of archives looking for an answer.

I put a little spreadsheet together today. In addition to conventional "$ per watt" breakdown, I have also included "$ per dBm". It basically tells you how much each additional decibel of gain over 100 watt output power will cost you based on the estimated power output , purchase price and gain as compared to your typical barefoot rig. For power output I have made some rough estimates as to how much power a given amplifier can produce. The prices I have collected today from various vendor or dealer web sites.

I currently have an AL-82, and am getting tired of all the band switching etc. My only real issue with the KPA-500 is the output power of only 500 watts. Just how much of a hit will I take by going from 1500 watts to 500 watts... I chase DX, via RTTY and CW mostly, and some SSB. I get DB, and realize that I will take a roughly a 5 db loss in signal, which is one S-unit... Will the KPA-500 take key down for 10 or more minutes at full power?? Is there anyone on here that has gone from 1500 to 500 watts, and if so, can you tell me a bit about it? How does the LPA-500 operate on MARS frequencies?

Last time that was available was the Swan 500 series and the Hallicrafters SR-500 Tornado. The former was an affordable high power rig that sometimes developed a serious drifting problem and the latter was a really fine rig - produced near the end of that company's manufacturing run. Hallicrafters did also build the SR-2000 Hurricane (2Kw using 8122 tubes) - another fine rig of that era. Over the years I owned both of those Hallicrafters rigs and used to wish that I had kept one or the other. Now that I have the K-Line, there is no need. I have the 500 Watt XCVR and all the advantages that microprocessing affords us in the new rigs. I am not sure that I would buy a KPA2000 or similar, if it was available. I find that 500 Watts really does me just fine. But............ I am not a DXer or contest op.

That's a tad extreme. That's 45 second transmit and 75 second receive - more than enough time to cool down even with fan set to NORM, and not reach speed 6 on its own. When I'm on FSK441 on 6 meters, I sometimes set it to 5 to help keep it from going to the highest speed at the end of a cycle while running 500+W. That's 30 seconds transmit and 30 seconds receive. It tends to cool to 58-59 degrees before the next cycle. The overall swing is around 12-15 degrees after 5-10 minutes. Sometimes, a QSO may take 45 minutes, even multiple hours to complete a full exchange. It can also be as short as 3-5 minutes to get the reports across and acknowledgements received. I don't know what Elecraft's opinion is on this, and would be curious to know. I tend to think that, since the temp is going to get up high anyway, I'd rather not let it get too cool during the receive cycle. I'm not sure that letting the temp cycle high and then real low is a good thing. Is it good to cycle wide, or keep the width of the cycle a little narrower? Power fade with high temp is also a factor.

Yes you can run the KPA500 in a RTTY contest at 500 watts calling CQ and working stations hour after hour. I've done it and it works just fine. The fan automatically increases speed as necessary. It tends to stabilize at speed 5 and only goes to speed 6 for short periods of time. Since Elecraft put in 6 fan speeds and since speed 6 has the ability to quickly cool it back down to speed 5 then I am of the opinion that I am operating the amplifier within its design limits. My antennas are resonant and my SWR is low. 73, Mike K2MK Johnny Siu wrote > May be I would like to ask the question from another angle.?

Hi Nick, Interesting idea, but I find the table impossible to read without line breaks. To correct a fundamental error -- dBm is dB referenced to 1 mW. 1W is 30 dBm, 5W is 37 dBm, 100W is 50 dBm, 500W is 57 dBm, 600W (the output of a KPA500) is 57.8 dBm, 1 kW is 60 dBm, and 1.5 kW ks 61.78 dBm. In other words, dBm describes the power in Watts. dB is 10 log (P2/P1). It's also 20 log (V2/V1) if the voltages are measured in the same impedance. If we want to talk about power referenced to 100W, the correct unit is dB, not dBm. 73, Jim K9YC From ktalbott at gamewood.net Sat Apr 25 12:27:10 2015 From: ktalbott at gamewood.net (Kenneth Talbott) Date: Sat, 25 Apr 2015 12:27:10 -0400 Subject: [Elecraft] Considering a KPA-500 In-Reply-To: <78anja5m1sieacmhfv9807uv8js0vgk8hv@4ax.com> References: <1232497036.4121963.1429945763470.JavaMail.yahoo@mail.yahoo.com> <78anja5m1sieacmhfv9807uv8js0vgk8hv@4ax.com> Message-ID: <005501d07f74$aeb5ac60$0c210520$@gamewood.net> QED -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of mcduffie at ag0n.net Sent: Saturday, April 25, 2015 10:49 AM To: elecraft Subject: Re: [Elecraft] Considering a KPA-500 On Sat, 25 Apr 2015 07:09:23 +0000 (UTC), Harry Yingst via Elecraft wrote: > I think some people take this HOBBY way to serious ;) Define too serious.

If not, do we need to turn it down to 300W? > Can anyone share with real life experience of using KPA500 in RTTY contest? I have done that many times, and have posted that IN THIS THREAD. When the KPA500 was in beta test, I was loaned a KPA500 for the weekend of a major RTTY contest and told to "run it with all the lights lit." I did, and it worked great. I bought one as soon as I could, and regularly run it in RTTY contests with all the lights lit. According to my calibrated LP-100A wattmeter, I get more than 600W out into a matched load on all bands except 6M, where I get at least 500W. The KPA500 is VERY well protected. The fan will speed up as the output devices warm up, and if the SWR is too high, drive will be reduced by a voltage divider and output power will be reduced. In an RTTY contest, if you're in Run mode (calling CQ) and getting answers to most calls, the fan will run at a medium speed. If you're not getting answers, it will get loud, but the amp will keep on going at full power. I run JT65 and other WSJT modes on 6M for weak signal work, mostly at full power. Likewise, I run JT65 on 160M, at power levels anywhere between 10W and 600W, depending on conditions. Again, the KPA500 gives me full power. The fan will usually speed up a bit near the end of a JT65 transmission. To correct a perceived misunderstanding about JT65 and operating power. JT65 is a WEAK SIGNAL mode, NOT a QRP mode. On the HF bands, it is considered good practice to run fairly low power on JT65, JT9, and PSK31 so that stations with lousy receivers are not overloaded, and also because these modes have good enough noise rejection that relatively little power is needed IF you have decent antennas, and IF both stations have relatively little RX noise. A good USB sound card can easily improve JT65 decoding by more than 10 dB -- that's 10X the power. An example -- a year or so ago, I ran a sked with a guy in ND on 160M. I have very good TX and RX antennas on 160M with a Tascam US100 USB sound card, and I heard him just fine, even though he was running only about 50W. As I recall, his signal was about -12 or -14. But he didn't hear me at 40W, 100W, 200W. I had to go to 400W to get over his RX noise! This is not uncommon -- I can often decode 8-10 signals per pass on 160M, many of them from east of Chicago, with signals in the range of -14 to -20, but I've got to run 400-500W to get them to hear me. By contrast, NO3M, whose 160M station in western PA has very good RX antennas, consistently hears me running 5W on CW. 73, Jim K9YC (near Santa Cruz, CA) From k2vco.vic at gmail.com Sat Apr 25 12:51:40 2015 From: k2vco.vic at gmail.com (Vic Rosenthal 4X6GP/K2VCO) Date: Sat, 25 Apr 2015 19:51:40 +0300 Subject: [Elecraft] Couple of K3 questions Message-ID: <553BC61C.2050806@gmail.com> I have 2 questions about feeding the two receivers in my K3. 1) Say I want to split an antenna and feed both the RX input and the AUX BNC input.

If it had columns to start with, they went away in the email for me -- maybe not for others. The real measure is $US/dB gained at the other end, but see below. dBm is power in dB referenced to 1 mW. 1mW=0 dBm. 1W=+30 dBm. 100W=+50dBm. 700W [KPA500 full bars]=+58.45dBm. 1500W=+61.76 dBm With larger powers measured in watts, it is common to use dBW -- power in dB referenced to 1 watt. 1W=0dBW. 100W=+20dBw. 700W=+28.45dBW. 1500W=+31.76dBW. dBW=10*log(power), which is a tad simpler. 1 S-unit is [nominally] 6 dB with S9=50uV at receiver input. If the input Z is 50 ohms, that equates to -73 dBm. $US per S-unit at the other end sort of says it. Would be interesting to see what the $US per S-unit is for various antenna arrangements. There is also a "panadapter gain" [similar to "coding gain"] in that being able to watch the whole pile-up lets you find the guy he just worked and gives you an advantage, in dB. If you live in the middle of the country, there is a "Stepp-ir gain" in that you can reverse that antenna almost instantly in a contest. I don't know how to quantify P3 gain or Stepp-ir gain however. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 4/24/2015 11:48 PM, Nick - VE3EY wrote: > In addition to conventional "$ per watt" breakdown, I have also included > "$ per dBm".

You can bet that Elecraft did that throughout the design process, and probably in final test of the power modules. I know the guy who did that testing. :) I've done it myself. It remains clean at the highest power I can get out of it, which varies a bit depending on the load Z between 600W and 700W. I've published a link to those measurements several times on this reflector. k9yc.com/P3_Spectrum_Measurements.pdf and k9yc.com/FTDX5000_Report.pdf The highest power in these reports is 550W, but I've measured up to 650W and the sidebands get slightly wider (5-10%) and a few dB stronger. > Elecraft have also said, in the operating manual, that the time limnit is 10 minutes key down.

It's pretty difficult to overdrive the KPA500 -- if you supply more drive than it wants, it will insert an attenuator between the input connector and the power amp stage to keep the power within design parameters. Protection circuitry in the K3, KX3, KPA500, and KAT500 is set to prevent destructive overheating and keep the signal clean.

I just > attended a Elecraft workshop defiantly want the updated synthesizer. Generally speaking the auto tuner is a good deal, it gives you some flexibility with antennas. If however all of your antennas are resonant and under 1.2:1 SWR, you may not need it. All K3's are dual-VFO. You can RX/TX on either, or you can RX on A and TX on B. I believe all K3's are now shipping with the updated synth as stock. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org From elecraft at mailman.qth.net Sat Apr 25 17:39:50 2015 From: elecraft at mailman.qth.net (Harry Yingst via Elecraft) Date: Sat, 25 Apr 2015 21:39:50 +0000 (UTC) Subject: [Elecraft] K3 Must have upgrades In-Reply-To: References: Message-ID: <118589373.4386299.1429997990529.JavaMail.yahoo@mail.yahoo.com> You can get a Very Good system for under $4000; are?you primarily SSB or a CW OP (that will help in filter selection)/.

The dual VFO is included with even the most basic K3. Did you perhaps mean the KRX3 subreceiver? That allows you to listen to two signals simultaneously - one in each ear. Without the KRX3 you listen to only one VFO at a time, but you can swap between VFO A and VFO B easily. That is usually done when operating SPLIT, and mostly occurs when working a rare DX station. If you are buying a new K3, you get the new synthesizer. There are a bunch of "ifs" to your 'perfect' configuration: If you want 100 watts output, order the K3/100, for QRP order the K3/10 If you are working DX and need to hear the DX station as well as a place in the pileup, then add the KRX3 If you want to run transverters or want the IF output or need an RX ANT input, then add the KXV3A If you do not have resonant antennas for all bands you intent to operate, then order the KAT3 If you want to add 2 meters, order the K144XV option (or use an external transverter). With the K144XV, you may want to add the K144RFLK reference lock for the K144XV. If you want a panadapter display, order the P3. If you want a large-screen display adjunct to the P3, add the P3SVGA If you want to use the K3 for SWLing, add the KBPF3 If you do a lot of voice operating and want a voice recorder, add the KDVR3 If your K3 will be subject to temperature variations and you want a more stable frequency, add the KTCXO3 IF you will be operating data modes that require extreme frequency stability, use a 10 MHz frequency standard and add the K3EXREF option in the K3. You may want to add the PR6-10 receive preamp depending on your antenna situation for 6 and 10 meters. Filter selection will depend on your operating choices. The filters are 'roofing filters' to protect from strong adjacent signals as may be encountered in contesting or DXing. The DSP filters provide the ultimate filter widths even without the optional roofing filters. If you want FM operation, order the KFL3B-FM 13kHz filter - you may want this filter for SWLing. If you do a lot of AM transmit, order the KFL3A-6K (although the 13kHz filter will also work, but is not optimum). If you operate SSB in contest situations, you might want either the KFL3A-1.8K or the KFL3A-2.1K For CW contesting or working DX in a pileup, you may want the 400 Hz KFL3A-400 For even more extreme contesting, you can add the KFL3A-250 250 Hz filter If you like to tune the CW bands using a wide filter width, you may want the KFL3-1.0K 1 kHz filter. Remember that there are only 5 filter slots in the main receiver and 5 in the subRX. If you plan to use the KRX3 subreceiver for diversity reception, put the same filters in both the main and the sub (and you may want to use all 8 pole filters - including the KFL3A-2.8_2.7sw filter swap - the 2.7 5 pole comes stock with the K3 and KRX3) With options and filters tailored to your operating needs, you can keep the price below $4000. The additional filters can add up quickly, so choose wisely. That is about the best I can do. As I said, let your desired operating preferences guide you. If you are not going to use a particular option, leave it out. It is easy to add options later, especially if you build the kit so you know how it goes together. The kit is not difficult if you can 'operate' a screwdriver and plug in boards and follow the instructions correctly. 73, Don W3FPR On 4/25/2015 4:32 PM, Becar Family wrote: > Elecraft Team, > > > > I would like to order my first K# I am not understanding all the add in > option for the K3. > > I would like the auto tuner, The dual VFO the 100 watts is a must.

That was reduced to 110 W to place an upper limit on IMD. > Someone should put the amp on an spectrum analyser while running at 700 wats to see whatr it looks like while being overdriven. You can bet that Elecraft did that throughout the design process, and probably in final test of the power modules. I know the guy who did that testing. :)? I've done it myself. It remains clean at the highest power I can get out of it, which varies a bit depending on the load Z between 600W and 700W.? I've published a link to those measurements several times on this reflector. k9yc.com/P3_Spectrum_Measurements.pdf and k9yc.com/FTDX5000_Report.pdf The highest power in these reports is 550W, but I've measured up to 650W and the sidebands get slightly wider (5-10%) and a few dB stronger. > Elecraft have also said, in the operating manual, that the time limnit is 10 minutes key down. Did they put that line in the manual just to take up space or is it purely CYA? That's a reasonable spec based on my observations with a thousand or more hours of use. > > Jusdt because some people are overdriving the amp and getting away with it doesn't mean it was designed for it. It's pretty difficult to overdrive the KPA500 -- if you supply more drive than it wants, it will insert an attenuator between the input connector and the power amp stage to keep the power within design parameters. Protection circuitry in the K3, KX3, KPA500, and KAT500 is set to prevent destructive overheating and keep the signal clean.

WSJT digital modes have apparently have greatly helped smaller stations (and "no code Experts) make contacts (not necessarily QSOs, by my definition). Here QRO+ power levels improves the success rate. Often with HB PAs. The FCC statement " only enough power need to provide communications", has some meaning here ! W7CS To correct a perceived misunderstanding about JT65 and operating power. JT65 is a WEAK SIGNAL mode, NOT a QRP mode. On the HF bands, it is considered good practice to run fairly low power on JT65, JT9, and PSK31 so that stations with lousy receivers are not overloaded, and also because these modes have good enough noise rejection that relatively little power is needed IF you have decent antennas, and IF both stations have relatively little RX noise. A good USB sound card can easily improve JT65 decoding by more than 10 dB -- that's 10X the power.

I have built a bunch. For grins, I plugged in my 10 meter amplifier figures to the VE3EY database. The dollars per watt worked out to $0.053 and the cost per 1 dB of improvenment worked out to $20.05. I was especially surprised at the 5 cents per watt figure. It has all sorts of protection circuits and is bullet proof. Includes the HV supply too! Manual tune though. I also have a KPA-500 and really love it. I use it for almost all my casual operating. It is ready to go instantly, while the homebrew one requires a long warmup.

If you instead installed Control Board J1 and J2 in anticipation of adding the KAF2 or KDSP2, you need to add a wire jumper between J1 pin 1 and J2 pin 1 and another between J1 pin 2 and J2 pin 2 before you can hear any audio from the RF board. If that is not the problem, take a look at the connector soldering on the Control Board and the Front Panel Board. Are all pins soldered - especially pin 1 on the Front Panel. Examine those boards carefully for solder bridges. Follow the audio path on the schematic for the Control Board starting on the right side of the schematic at the PD1 and PD2 points, through the MUTE transistors Q6 and Q7, then onto the Front Panel AF1, AF2 and AF3 signal lines. You may have to remove the Front Panel metalwork to gain access to those signal paths as they move to the front panel board. Touching a screwdriver to the AF1, AF2 and AF3 lines should result in a bit of hum pickup. 73, Don W3FPR On 4/26/2015 6:51 AM, Kevin Hulina wrote: > I am going through the tests of my newly built K2 and I'm getting no > receive audio.

Interesting results in that thje least expensive (811H) and most expensive (AL-1500) Ameritron amps are in the top five if you sort by USD/watt. I was surprised by how well the OM Power terode amps did. I expected the Alpha 9500 to score lower and it tied with the Acom 2000. All of the solid state amps are at the bottom of the list if the sort parameters are USD/watt and solid state. The ALS-1306 is the best of the SS amps from that point of view.

This week it rained, it hailed, it snowed, and it was sunny. Daytime high temperatures varied from 40 degrees to 75 degrees. My daffodils are finally succumbing to the distress. After four weeks of being bright yellow they are beginning to fade as are all the native trillium. The sun has been active over the last week causing a lot of noise. When I looked at Space Weather a few moments ago I saw the solar flux number is dropping. Much of the noise had been coming from a persistent solar wind. It currently appears to be slowing down. Hopefully this will provide less noisy conditions for our nets.

I also have an AlexLoop, and I always switch off the tuner when using the AlexLoop. True, you may be getting the SWR lower by using the tuner, but that does not mean that the loop is radiating any better. Use the tuning control on the loop and get the SWR as low as possible... yeah, sometimes it's darn touchy. But as long as the SWR is minimized, the loop will be radiating as well as possible. Even if the SWR is 1.5 or so. The point of using a loop is that it is a resonant circuit, and when you feed it with energy at it's resonance point, the loop will radiate. Practice getting the SWR down on higher bands (it's usually easier and less fussy there). Then move to lower bands and practice there. And, remember... -anything- in the nearby field will affect the tuning of the loop. Even you. 73 de Ray K2ULR KX3 #211 On Apr 26, 2015, at 1:59 AM, Robert Sands wrote: > I am using it with my KX3 in Kona, Hawaii. Works well but not quite > as well > as the MFJ 17 foot vertical.

I modified the spreadsheet a bit and re-sorted it. First, since we here in the US are permitted only 1,500W, I set max power for those amps with higher power ratings to that value. Second, just as Nick has included his used Alpha 99, I added my used Ten Tec Titan 425s. k9yc.com/PwrAmpdB.png There are many features and properties of power amps that go far beyond pure dB per dollar. some examples: The ACOM 1010 is a reasonably compact competitor to the KPA500, but it doesn't cover 6M. I bought one used from K6SRZ (to have another amp for CQP), who bought a KPA500 just to get 6M. Also, my occupied bandwidth tests show that the KPA500 is a bit cleaner than that ACOM 1010. And the 1010 is a single-voltage amp. It must be rewired to change it. The KPA500 can be switched by removing, rotating, and reinserting the fuse block built into the power plug. The ACOM 1000 does cover 6M. Both it and the 1010 have manual antenna tuners built in. Some of these amplifiers have built-in tuners, some of those tuners are automatic or have memories. Some of these amps are much better built than others. My Ten Tec Titans use high quality vacuum relays with logic to prevent hot-switching, as do the Alphas. The Ameritron amps I've seen use much cheaper open-frame relays, so their switching is much slower. My Titans are quite clean -- P3 measurements of both the KPA500 and the Titan look exactly like the K3 at the drive level required for rated power. But the Titans, like the lower cost ACOMs, are "manual everything. 73, Jim K9YC From chadwasinger at outlook.com Sun Apr 26 17:48:32 2015 From: chadwasinger at outlook.com (Chad Wasinger) Date: Sun, 26 Apr 2015 16:48:32 -0500 Subject: [Elecraft] K3 Line Add-on's Wanted Message-ID: Hi Group, Looking for a few items to get my K3/10 up to personnel specifications before buying new. - K144XV - K144RFLK - KXV3A (version 'A' only) - TCXO - K3EXREF - KFL3B-FM - P3 with or without SVGA (kit or factory) - KAT500 (kit or factory) Please let me know if you have any of these items as spares or still in kit form.

The Chief Op (and maybe the only op) is Alan, F6BFH. I say it is a "mini" DXpedition because it is apparently a part time thing, the main purpose of the island visit being for scientific purposes--and, only one operator that I know of. What's interesting about this operation, and pertinent to this reflector, is the equipment being used. According to the QRZ.com page, they are using a KX3 and 100 watt amp. There is also an FT-897 available, which I assume is a back-up rig. While I'm sure there have been other KX3's used for trips to DX locations, I wonder if this is the first to an otherwise "popular" DXpedition location. So far I have worked TX5P on 3 bands, 17, 20, and 40 meters. All of these contacts were made rather easily, thanks to the availability of my 2nd RX in the K3--the split was "5 to 10 up"! However, as is too often the case, the behavior of the calling stations was appalling--particularly on 20 and 40 meters. It was obviously frustrating Alan (I assume it was him), and he was constantly having to send a long series of "dits" to get people to stop transmitting on top of the station he was trying to recognize. He even commented specifically, several times, about the lack of "discipline"! Even though he, repeatedly, asked others to allow ONLY the station he was calling to transmit, a huge number of other stations totally ignored his request. Ridiculous! I am constantly amazed at the rude, inconsiderate behavior of some people in these DX situations. I know I'm "preaching to the choir", and that this has gone on forever, but I absolutely don't understand why people think what they are doing is productive! In the time it took Alan to identify a station, he probably could have worked a half dozen more! Just over the brief period of time I was listening, I would guess that 40 or 50 contacts could have been made while only 6 or 7 were actually accomplished. By the way, I had a similar experience the other day just trying to work K6KPH, which had activated the KPH commercial radio site. This was not a split frequency thing, so it was even worse. You would think North Korea had been activated! He had all but my last letter, and asked me to repeat. Still a couple of dozen other stations jumped in right on top! I'm not sure I heard my report correctly, but I just didn't want to fight it. Absurd! Anyway, it will be interesting to see how many subsequent KX3 operations occur. That radio is certainly getting a lot of attention!

On a regular basis, the DX columns in QST and CQ were more or less verbatim copies of your complaint. Even though of course the piles were way smaller and the bands were much better in those days. But apparently it ain't ever gonna change. An ugly scourge today is the deliberate qrm, something that rarely happened in the old days. Apparently some guys get ticked off when a pileup takes up some of the precious spectrum where they could otherwise be calling cq, and they transmit endlessly on top of the dx. It's worldwide: some of the worst ones come from certain Euro countries. Another present-day scourge is the up-cop, something that didn't exist in the old days. Anyway, the point of your post, that a KX3 works fine as a dx station, is a good one and I bet we see many more in the future.

Im sure you can find quite a number of them in every state, they are prolific out here.

Of course everyone would have their own personal concerns, so you could add a place in the spreadsheet where the user could weight the various factors appropriately.

CW is a carrier amplitude-modulated by a series of square waves, and the harmonics of which that square wave consists excite IMD in the gain stages! The IMD from those harmonics is what we hear as clicks. The faster the rise time, the greater the order and magnitude of the harmonics produced, so the louder and wider are the clicks. An important reason the K3 is MUCH cleaner than nearly all other rigs is that they have carefully shaped the keying waveform to minimize the amplitude and order of those harmonics.

There are operators who do not copy CW, but can (sometimes) recognize their own call, or maybe have some kind of CW decoder. Their technique is to call whenever the DX is not transmitting, and wait for their call to appear.

According to the QRZ.com page, they are using a KX3 and 100 watt amp. There is also an FT-897 available, which I assume is a back-up rig.

All of these contacts were made rather easily, thanks to the availability of my 2nd RX in the K3--the split was "5 to 10 up"! However, as is too often the case, the behavior of the calling stations was appalling--particularly on 20 and 40 meters. It was obviously frustrating Alan (I assume it was him), and he was constantly having to send a long series of "dits" to get people to stop transmitting on top of the station he was trying to recognize. He even commented specifically, several times, about the lack of "discipline"! Even though he, repeatedly, asked others to allow ONLY the station he was calling to transmit, a huge number of other stations totally ignored his request. Ridiculous! I am constantly amazed at the rude, inconsiderate behavior of some people in these DX situations. I know I'm "preaching to the choir", and that this has gone on forever, but I absolutely don't understand why people think what they are doing is productive! In the time it took Alan to identify a station, he probably could have worked a half dozen more! Just over the brief period of time I was listening, I would guess that 40 or 50 contacts could have been made while only 6 or 7 were actually accomplished. By the way, I had a similar experience the other day just trying to work K6KPH, which had activated the KPH commercial radio site. This was not a split frequency thing, so it was even worse. You would think North Korea had been activated! He had all but my last letter, and asked me to repeat. Still a couple of dozen other stations jumped in right on top!

I think. Nope. It's a bunch of square waves, and any square wave is composed of an infinite series of harmonics. Those frequencies are present in the drive signal (from small signal circuits to power amp circuits, whether in the rig or in a power amp), and if either is non-linear, distortion is produced. It's important to realize that ANY non-linear element produces both IMD and harmonics -- indeed, in-band IMD is the result of the mixing of harmonics in a non-linear circuit. Quantities like IMD and THD are simply different ways of quantifying the distortion produced by non-linear devices! 73, Jim K9YC From w3fpr at embarqmail.com Mon Apr 27 07:51:38 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Mon, 27 Apr 2015 07:51:38 -0400 Subject: [Elecraft] Amp power per $$ spreadsheet download In-Reply-To: <484AC11F-6549-43F8-824E-6CE13708386C@gmail.com> References: <20150425160135.6504532.94628.5098@gmail.com> <553BE7A5.4060307@nycap.rr.com> <553C4F0E.5070203@socal.rr.com> <553D59EA.4010104@audiosystemsgroup.com> <553DC6A1.3020408@audiosystemsgroup.com> <484AC11F-6549-43F8-824E-6CE13708386C@gmail.com> Message-ID: <553E22CA.6060303@embarqmail.com> Vic, Yes that will create harmonics, but at audio frequencies related to the keying speed, not harmonics of the RF frequency. It is those extra audio frequencies which generate keyclicks - you may call it IMD or not, but it is undesirable. 73, Don W3FPR On 4/27/2015 1:33 AM, Vic Rosenthal wrote: > Sharpening the envelope is harmonic distortion, not IMD.

My K2 has been working fine for a few months now and I was finding the background noise that gets pulled in very tiring, so I decided to buy the KDSP2 DSP filter. The build went fine and so did the install. After turning on the K2 I checked that the menu settings were all there and followed the manual. I then realised I did not have the speaker plugged in, so I plugged it in while powered up. I got a loud pop through the speaker, then silence. I thought that perhaps I had missed a menu setting whereby I would have to enable the KDSP2 but couldn?t find anything so obvious. I built the K2 with the Rework Eliminators installed, so I removed the KDSP2 and placed the header back in place and still I had no audio. I have also removed my KSB2 and KIO2 module so now I am back to the bare K2, but still I have no audio. I can only assume that something failed when I plugged in the speaker whilst still powered on. I have tried injecting a signal in with the Elecraft wideband noise generator and the cheap and dirty signal tracing document but with the headphones plugged in and the AF and RF gain at full, I hear nothing at all at any point, only a very faint hissing. Although the signal does register on the S meter. I have also followed the troubleshooting in the manual and gone through the full alignment procedure as recommended but still no luck. Could someone help with a place to begin to try and track down the faulty component or components. .

Inject an audio signal into the AF amp and see if you get anything out. Check the voltages around U9 to make sure they are ok. If the AF amp is working, then step back and check out the muting circuit by injecting your audio signal just before. If you have an oscilloscope, this may be helpful in seeing where the signal is being lost. It may be a dry joint that you disturbed when you were working on the radio. It?s also possible a component has failed (eg. C27) and is shorting out the signal. Or it may be U9 itself has failed. The AF circuitry is fairly simple, so shouldn't be too hard to track down. 73, Matt VK2RQ > On 28 Apr 2015, at 5:41 am, Mick Hall wrote: > > Hi. > > My K2 has been working fine for a few months now and I was finding the background noise that gets pulled in very tiring, so I decided to buy the KDSP2 DSP filter. > > The build went fine and so did the install.

It is about the same volume as the pop you may hear when powering the K2 on. That is the sound of the output electrolytic in the audio amplifier charging or discharging. It is not usual to cause damage by plugging in the speaker, even with power on, although the speaker itself could be damaged - try another speaker or your headphones in the EXT SPKR jack. Since you have no speaker audio with the KDSP2 removed - did you plug in the rework eliminator correctly? Did you plug the speaker connector into P6 on the RF board? If you used P6 on the Control Board, there is no audio at that point. Do you hear audio in the headphones? Is the tab on P6 broken off? If it is, did you plug the speaker connector in backwards? The 'ears' of the header must face the front of the K2. 73, Don W3FPR On 4/27/2015 3:41 PM, Mick Hall wrote: > Hi. > > My K2 has been working fine for a few months now and I was finding the background noise that gets pulled in very tiring, so I decided to buy the KDSP2 DSP filter. > > The build went fine and so did the install.

You can do the TX Gain Calibration manually through the menu. Give that a try on a few bands - if it is successful, try the K3 Utility process again, or just do all bands manually. The manual procedure does the same thing as K3 Utility, except the Utility makes it 'pain-free'. 73, Don W3FPR On 4/27/2015 4:16 PM, Michael Raskin wrote: > I KNOW this is cockpit error (it always is) so I?m hoping someone can > tell be what I am doing wrong.

They are on the air most Saturdays from 1700-2300Z, if an operator is available. Amateurs who visit this interesting site are welcome to operate K6KPH, and Richard and his crew of volunteers are most hospitable. We've been to the receiving site twice; once on "Night of Nights," which is the anniversary of the last commercial Morse transmission from KSM/KPH. Last summer, on the way to Sea-Pac, we also visited the transmitter site at Bolinas, and revisited the receiving site. We were served pastries and orange juice using the plates, forks and glasses that still sport the RCA logo. The trip also included a stop at the Elecraft factory, where Lisa gave us a first-class tour. So, if you have the opportunity to be in the vicinity of Point Reyes on any given Saturday, it's well worth a visit. And if you have the opportunity to hear a presentation by Richard Dillman, the Chief op, definitely do so! He spoke at Pacificon last October. Sometimes the group also sets up a remote to the site during Pacificon. 73 de Jim - AD6CW On 4/26/2015 6:55 PM, dyarnes wrote: > Hi All, > > By the way, I had a similar experience the other day just trying to > work K6KPH, which had activated the KPH commercial radio site.

You'll need the utility program to do that. The KPA500 goes into standby on an error condition (SWR too high etc), so some info may be there for the seekers... A temporary failure (flexing antenna contacts in the wind, a bird landing in the wrong spot on the antenna) would trip the protection algorithm. Rick nhc On 4/27/2015 3:04 PM, Milverton M.

In fact, if you add up all the harmonics of a sine wave, in various proportions, forever, when forever is over, you can have created any waveform possible. For MATH, search Wikipedia for "square wave". The issue this unrelated thread morphed into delves into a really big issue in radio design. We think of the keying or the signal from the microphone as just a voltage that varies with time. For a paddle, it's there or not there. For the microphone, it's a voltage whose amplitude varies with time as we speak. Because of the MATH, those signals can also be represented as the sum of individual signals at specific frequencies with individual phases, and that's how the electronics treats them. Filters, amplifiers, mixers, and other components do not always treat all those different signals the same way, distorting their amplitude or their phase or both relative to each other. It would be great, and college would be a lot more fun and a lot less math if this weren't true, but sadly, it is. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 4/27/2015 4:42 PM, Michael Zolno wrote: > Jim, > > Can you point to a math based reference for this.

They like all caps? ;-) But they are cool ops too! The KPA500 Faults at 90 degrees C. The highest fan level kicks in at 80 degrees. And for those who were wondering, the fan first turns on when the measured temperature gets to 50 degrees C. As my friend KK7P noted a few days ago, the fan will run much less in the antarctic in June, and much more in the Sahara about the same time of year. It really depends on the environment it (and you) are in as to how much it will run, and how long it takes to get to a high fan level. Enjoy your Elecraft devices. And don?t worry about pushing the KPA500 too much. It has proven that it can take it, contest after contest. 73!

They merely use a traditional tuned final design that has the ability to match into a moderate range of impedances. This can be up to a 3:1 SWR in certain limited circumstances (less on 160m). If you have resonant antennas, you'll be just fine - even at the extremes of 75/80m in many cases. If you have a very narrow band antenna, not so much. The Acoms have no more of an "antenna tuner" than did an SB-220 or a 30L1 for example. Also, aside from the new Solid State Acom 600S (with a switching power supply), all of the Acom amplifiers use traditional linear power supplies with multiple taps on the primary which allows using them on 120 to 240v, single phase. Needless to say, using them on 240v is best for numerous reasons. 73, Bob W5OV -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: Sunday, April 26, 2015 5:35 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Amp power per $$ spreadsheet download On Sat,4/25/2015 7:35 PM, Phil Wheeler wrote: > Good job, Nick.

I modified the spreadsheet a bit and re-sorted it. First, since we here in the US are permitted only 1,500W, I set max power for those amps with higher power ratings to that value. Second, just as Nick has included his used Alpha 99, I added my used Ten Tec Titan 425s. k9yc.com/PwrAmpdB.png There are many features and properties of power amps that go far beyond pure dB per dollar. some examples: The ACOM 1010 is a reasonably compact competitor to the KPA500, but it doesn't cover 6M. I bought one used from K6SRZ (to have another amp for CQP), who bought a KPA500 just to get 6M. Also, my occupied bandwidth tests show that the KPA500 is a bit cleaner than that ACOM 1010. And the 1010 is a single-voltage amp. It must be rewired to change it. The KPA500 can be switched by removing, rotating, and reinserting the fuse block built into the power plug. The ACOM 1000 does cover 6M. Both it and the 1010 have manual antenna tuners built in. Some of these amplifiers have built-in tuners, some of those tuners are automatic or have memories. Some of these amps are much better built than others. My Ten Tec Titans use high quality vacuum relays with logic to prevent hot-switching, as do the Alphas. The Ameritron amps I've seen use much cheaper open-frame relays, so their switching is much slower. My Titans are quite clean -- P3 measurements of both the KPA500 and the Titan look exactly like the K3 at the drive level required for rated power. But the Titans, like the lower cost ACOMs, are "manual everything. 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 w5ov at w5ov.com From mike.harris at horizon.co.fk Tue Apr 28 07:43:30 2015 From: mike.harris at horizon.co.fk (Mike Harris) Date: Tue, 28 Apr 2015 08:43:30 -0300 Subject: [Elecraft] Amp power per $$ spreadsheet download In-Reply-To: <000601d081a2$d5ed05f0$81c711d0$@W5OV.COM> References: <20150425160135.6504532.94628.5098@gmail.com> <553BE7A5.4060307@nycap.rr.com> <553C4F0E.5070203@socal.rr.com> <553D59EA.4010104@audiosystemsgroup.com> <000601d081a2$d5ed05f0$81c711d0$@W5OV.COM> Message-ID: <553F7262.2070603@horizon.co.fk> Resonance doesn't mean 50 ohm.

The good news is they work! One observation in the installation - it seems that the process in the instructions has one install the boards and then connect the cables. I found it easier to attach the cables and then seat the boards in the connectors. This is especially true if you have a sub rx and have two synth cards. One cable (J4 on the sub rx board) is in a connector that is at a 45 degree to the board and is low on the board. After struggling with the board in place, I pulled it, installed the cable then installed the board - easy. The same is also true for J84 on the sub rx board. I'll be very interested to see how the new RX plays in tomorrow's CWT.

I am not promoting any product here but thought this might be of interest to some: I purchased a made-in-China GPSDO model BG7TBL 10 MHz source from the "bay" web site. The price was good and It only took about two weeks for delivery.? This small unit comes with a power supply (wall wart) and small antenna that has about 15 feet of cable and an SMA connector. The antenna has a magnet on the back so it will attach to metal such as a rain gutter, tower leg, or?whatever. (It also seems to work Ok with the antenna inside of a wooden structure. When powered up it only took about 15 minutes to find a GPS lock.? I compared this unit to a Made-in-Japan Symmetricom? 58533A. It has stayed on 10 MHz frequency for several days with only a few degrees of phase shift difference between the two units. (I am not sure which ?unit has the phase shift but it is a small amount).? GPS timing must be very accurate to function.? Nearly all GPS satellites have?a Stratum One clock?on-board the bird. I believe this is more accurate than the over-the-air signal from WWV. I feel like purchasing items like this may be a bit of a "crap - shoot".? It may or may not get lost in shipment.? It may or may not work when you receive it.

I'll bet "BND END" will go away and the K3's will transmit once the FCC has formally acted and it has been published in the Fed Reg. Filters in the TX chain might require some mods of course. Depending on what the ultimate Part 97 rules say about this allocation regarding antenna size, height, power limits, and required EIRP computations, 100 W from a KPA3 into a compliant antenna could be QRPpp in EIRP. :-) 2200 m is another issue. Sensitivity on my K3 with the new synthesizer is just as Wayne said it would be ... low. There's also a LOT of noise down there, or at least there is where I live. I noticed that years ago when we were experimenting with LORAN-C aircraft receivers for locating busses and I had one in my truck [a receiver, not a bus] for a month or two. At 100 KHz, railroad tracks have some strange effects also. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 4/28/2015 4:16 PM, Jim Miller wrote: > Now we just need a TX solution to go with the new synths! > > Jim ab3cv From jmlowman at sbcglobal.net Tue Apr 28 20:02:14 2015 From: jmlowman at sbcglobal.net (Jim Lowman) Date: Tue, 28 Apr 2015 17:02:14 -0700 Subject: [Elecraft] Interesting In-Reply-To: <554007C9.4030905@socal.rr.com> References: <554007C9.4030905@socal.rr.com> Message-ID: <55401F86.5090801@sbcglobal.net> I heard elsewhere that Elecraft is ready for 630m when the FCC gives final approval.

Ummm ... don't know. Just because it receives very well down there [with the KBPF3], TX may require some mods to the filters, HW or FW. I'm pretty sure it will happen if the FCC ever acts. My K3 receives very well on 630 m. Most antennas at 630 m are verticals, we will all have to decide: a) how much can we afford in a tower; and b) what will the HOA accept as "reasonable accommodation." :-) > > How about the 2200m band? Is the K3 receiver sensitivity good enough, > that low in frequency? Wayne has already made it clear that MF/LF sensitivity falls off steadily below 300 KHz. I'm going to keep WSPR running on 137 KHZ for awhile, but I'm not holding my breath. Sensitivity seems to go down as stated, noise here rises dramatically. Honestly, I think expecting a radio to work perfectly from 100 KHz to 50,000 KHz is like asking the government to never make a misteak. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org From tscm4u at gmail.com Tue Apr 28 20:43:28 2015 From: tscm4u at gmail.com (J) Date: Tue, 28 Apr 2015 17:43:28 -0700 Subject: [Elecraft] FCC Proposes to Permit Amateur Access to 2200 and 630 Meters In-Reply-To: <660AADA6-A2FB-4A8B-B045-93347F0F66AA@gmail.com> References: <660AADA6-A2FB-4A8B-B045-93347F0F66AA@gmail.com> Message-ID: <000f01d08215$831bb6a0$895323e0$@gmail.com> It would also be good to see something in the 1750M (LowFer) band 160-190 KHz.

At least one of the experimental guys is doing so w/ the new synths. Only an amplifier is needed, depending on how much power you want to put out or need to reach the EIRP limit. Long antenna? Tower? Not necessary. The proposed power limit is 5W EIRP (or 1W EIRP in parts of AK if within 800km of Russia). As such, you could in theory put up anything and adjust your transmitter output to reach the EIRP limit. It levels the playing field for everyone, whether you have a 10 ft stick, 200ft top-loaded tower, or a phased array. No one antenna *should* radiate any more power in a given direction if the EIRP restriction is followed correctly. 67ft top-loaded vertical + 75-100W output (~5-8W ERP) has gotten me QSOs all over the US, including CW to the west coast. Work on your RX antenna(s) before worrying about the TX antenna on LF/MF..... esp with an EIRP limit. 73 Eric NO3M WG2XJM (Part 5 2200m + 630m) On 04/28/2015 08:18 PM, Fred Jensen wrote: > On 4/28/2015 5:02 PM, Jim Lowman wrote: >> I heard elsewhere that Elecraft is ready for 630m when the FCC gives >> final approval. >> I know that the K3 will receive on that band, but what will be needed to >> be able to transmit there (other than a very long antenna)? > > Ummm ... don't know.

I set up my K3 and KX3 with an antenna A/B switch so I could jump back and forth between them. It's very cool to see how similar the receivers are, despite their internal differences. Any signal, no matter how weak or how close to another, that can be copied on one can be copied on the other, and the audio picture in the phones is almost exactly the same.

At least one of the experimental guys is doing so w/ the new synths. Only an amplifier is needed, depending on how much power you want to put out or need to reach the EIRP limit. Correct. You need the KBPF3 and KXV3 options, and output is somewhere around 0.5-1.0 mW, varying a bit with the radio. Wayne N6KR > > Long antenna? Tower? Not necessary. The proposed power limit is 5W EIRP (or 1W EIRP in parts of AK if within 800km of Russia). As such, you could in theory put up anything and adjust your transmitter output to reach the EIRP limit. It levels the playing field for everyone, whether you have a 10 ft stick, 200ft top-loaded tower, or a phased array. No one antenna *should* radiate any more power in a given direction if the EIRP restriction is followed correctly. 67ft top-loaded vertical + 75-100W output (~5-8W ERP) has gotten me QSOs all over the US, including CW to the west coast.

Of course it is not linear and can not be used on ssb but in this band is not allowed ssb at least here in Europe. It can be obviously be used on CW and all digital mode that use FSK modulation. About the question oh harmonic in the MW broadcast band, this is the output of the amplifier at 135W (you must add 61 dB of the attenuator at the input of the spectrum analyzer): http://it.tinypic.com/r/33c5ieh/8 I do not know if this meets the requirement of the FCC but we have about 1 mW on the second harmonic and 0.02 mW on third and, if we add the selectivity of the antenna (my 25m high inverted L have a 1.5:1 SWR bandwidth of about 2 KHz), i think that the emission on the harmonics can not go far. If you are interested to the amplifier you can contact me at my e-mail address. 73, Fausto IK4NMF ----- Original Message ----- From: "Wayne Burdick" To: "Eric NO3M" Cc: Sent: Wednesday, April 29, 2015 5:31 AM Subject: Re: [Elecraft] Interesting > > On Apr 28, 2015, at 6:46 PM, Eric NO3M wrote: > >> K3 is ready now I thought... transmits 1mW out of the transverter port at >> 630M.

If not, then you probably need to replace some components in the KIO2 adapter board. The K2?s IO interface in NOT meant for RS-232 levels on all it?s lines. In fact only two of them can take the RS-232 levels. Make sure the K2 still operates properly at this point, the damage could have gone into the main microcontroller.

This extended coverage is made possible by the new synth (KSYN3A). After a lot of digging, we discovered the cause of the wide-band low-frequency noise. We also found a way to shift the passband of the KBPF3 lower. With a couple of simple modifications, the MDS (minimum discernible signal) can be improved by about 25 dB at the low end (100 kHz). Here are some test results (preamp off, 400-Hz bandwidth): 137 kHz -114 dBm FCC's proposed 2200 meter band 160 kHz -117 dBm low end of the "Low-Fer" band 250 kHz -126 dBm test frequency in the long-wave beacon band 472 kHz -133 dBm 630 meter experimental band This represents an improvement throughout the range, but especially at the low end. I believe -114 dBm MDS should suffice at 137 kHz, given the high band noise in this range. Another indication of how well the mods work: With no antenna connoted, the K3's S-meter now just barely flickers (S1) at 100 kHz. Without the mods, the no-antenna S-meter reading could be as high as S7 due to the noise source we've now identified (a voltage regulator). (By the way, this regulator noise had no impact on frequencies about about 500 kHz.) Here's a summary of the changes required: RF board: Add one leaded capacitor KRX3 (if applicable): Add one leaded capacitor KBPF3: Remove two inductors; parallel three new capacitors If you're interested in this low frequency range, and you'd like to try the mods, please email me directly. Note: To tune this range with the K3, you'll need the new synth (KSYN3A), a KBPF3 module (on the main and/or sub receiver), and a KXV3 module. A KXV3 is required because the antenna for the 100-500 kHz range should be connected to RX ANT IN or XVTR IN. The ANT1/ANT2 path goes through the T/R switch, which has a high-pass filter to protect the K3's fast PIN-diode T/R circuitry. 73, Wayne N6KR From kw1nd at comcast.net Wed Apr 29 22:16:26 2015 From: kw1nd at comcast.net (Mike) Date: Wed, 29 Apr 2015 22:16:26 -0400 Subject: [Elecraft] Dramatic improvement in K3 RX sensitivity below 500 kHz -- looking for testers In-Reply-To: References: Message-ID: <5541907A.4000905@comcast.net> And this is why we like Elecraft so much.

You need the KXV3 or KXV3A transverter interface and the KXBPF3 general coverage band pass filter. KXV3(A) provides an 8 MHz IF output for things like a P3, and a separate receiver input. You activate that with a tap on the RX ANT front panel button. I don't know at which frequency the receive path is switched as you ask, but it is definitely above 500 KHz. My K3, with new synthesizer, receives fine a bit below 160 meters using the ANT 1/ANT 2 connectors. It does NOT below 530 KHz, I have to use the RX ANT on the KXV3. I don't know between those frequencies, here in the New World, they are filled with bloviators of all kinds, and I ignore them. You'll need to look up "bloviator", I'm sure there's one or more equivalents in Spanish, possibly many. :-) This new range on the K3 is really cool! 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 4/29/2015 7:50 PM, Joe Subich, W4TV wrote: > > There should be no difference in antenna performance with the new > synthesizers.

No; this is strictly an issue below 500 kHz. All of the K3's band-pass filters already work exactly as they should. 73, Wayne N6KR From drewko1 at verizon.net Wed Apr 29 23:30:45 2015 From: drewko1 at verizon.net (drewko) Date: Wed, 29 Apr 2015 23:30:45 -0400 Subject: [Elecraft] Dramatic improvement in K3 RX sensitivity below 500 kHz -- looking for testers In-Reply-To: References: Message-ID: IIRC, original statement for the new board was -120 dBm at 475 KHz.

On my K3, with the mods, the MDS at 1.0 MHz is now -136 dBm, preamp on (400 Hz BW). Just keep in mind that in the lower frequency ranges, you'll want to use RX ANT IN or XVTR IN to avoid the loss of the high-pass filter in the T/R switch.

You are going to run in to a practical limit set by atmospheric and man made noise. If you assume a -147 dbm for a perfect receiver in a 500 Hz BW, used because the math is easier, and then subtract 60 db for expected value of noise on 80 meters, you should find that the K3 sensitivity greatly exceeds what could practically be used. I did not look at the noise figure for the K3 as I assume it is much, much better than the expected value of what the antenna will see. And, the environmental noise gets worse as you decrease frequency. I guess what I'm trying to convey is the idea that you already have a superb design. So, will you have done anything to the radio's characteristics in the higher regions of the spectrum to achieve better MF and down performance? 73, Barry K3NDM On 4/29/2015 11:55 PM, Wayne Burdick wrote: > On Apr 29, 2015, at 8:30 PM, drewko wrote: > >> IIRC, original statement for the new board was -120 dBm at 475 KHz. > That was conservative. > > >> Now saying -133 with the mods. > At least on my lab K3. > > >> Maybe broadcast band DXers would find it useful on the lower half of the AM band? > > Could be.

All of this with the K2' internal auto-tuner turned of. The antenna "alteration" I was trying wasn't providing the LDG auto-tuner with Zo values it liked so I was switching the K2's auto-tuner in and trying it across the various bands to see how it "played" with the altered antenna. After an afternoon of this I surrendered and restored the antenna to its original configuration, one the LDG auto-tuner tuned effortlessly. Note: the original system is a 36' vertical with 12 elevated radials an the auto-tuner at the base of the vertical. The LDG has always tuned that configuration effortlessly on 40 through 12. After restoring it back to its original configuration I went through the tuning cycle - K2's ATU off, hit the tune switch....yadda, yadda; that's the configuration I use - ATU off, K2 set to watch pwr out and reflected- the POUT mode. What I found was: the LDG tuned 40 through 12 effortlessly BUT, on 40 meters I observed 5 watts out and 2 watts reflected (prior to all of this, it was zero watts reflected). Given the vertical is back to its 36' configuration one would expect zero watts......so, I retuned several times but, same result. I could tell the LDG was tuning correctly and with 30 through 12 showing no reflected power I kept wondering of the K2 was "acting up." I found the internal ATU manual and start reading up on the "Using the ATU." I found this: As an alternative to CALS or CALP, you can tune up the ATU into a 50 ohm dummy load on each band using AUTO mode. This will cancel out most or all of the stray inductance and capacitance so that you can connect your external tuner or resonant antenna. After tuning up on all bands, put the ATU in to POUT or SWR mode> The matching network settings will not change. I ran through that sequence and...poof....no reflected power on 40 meters! Soooooooooo.....has anyone else experienced this "phantom," residual L/C? How does the internal ATU provide/introduce stray L or C while in the off position? I'm not complaining - the "fix" was easy....I'm just curious.....72 de Jim Rodenkirch K9JWV From w3fpr at embarqmail.com Thu Apr 30 09:17:37 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Thu, 30 Apr 2015 09:17:37 -0400 Subject: [Elecraft] K2's ATU "vagaries" In-Reply-To: References: Message-ID: <55422B71.2090903@embarqmail.com> Jim, I am not certain how you would set the KAT2 to OFF. That is not an option in the menu. Setting the ATU menu to CALP or CALS will electrically bypass the L/C elements in the tuner, but there will be some residual reactance in the tuner. The best method to "bypass" the tuner is to do as stated in the manual - tune (on each band) using AUTO mode into a dummy load and then set the ATU menu to POUT. The L/C combination last used for the TUNE on each band will be set when you return to that band. Note for KAT100 users - POUT is not an available menu option - you can use CAL which bypasses the L/C elements completely. 73, Don W3FPR On 4/30/2015 8:21 AM, James Rodenkirch wrote: > While altering my existing antenna system which includes an LDG Z11ProII auto-tuner at the base, I had to do quite a bit of "testing" from the shack; e.g., add a un-un, go to shack, hit the tune switch, watch power out and SWR.....switch to another un-un with a different ratio, follow same procedure.

You are going to run in to a practical limit set by atmospheric and man made noise. If you assume a -147 dbm for a perfect receiver in a 500 Hz BW, used because the math is easier, and then subtract 60 db for expected value of noise on 80 meters, you should find that the K3 sensitivity greatly exceeds what could practically be used. I did not look at the noise figure for the K3 as I assume it is much, much better than the expected value of what the antenna will see. And, the environmental noise gets worse as you decrease frequency. I guess what I'm trying to convey is the idea that you already have a superb design.

Both run all my Elecraft programs flawlessly, as well as my Propnet program for my 10M Automatically Controlled Digital Station on 28.1188 MHz. The Propnet program runs 24/7 and other than occasional updates has been working continously. I also use Fldigi 3.22.08 under Win 10 Preview, as well as HRD. I am SO looking forward to the final release this summer. I will probably upgrade all my computers to Windows 10 - it is that much better. I hated Win 8.0 with a passion! Win 8.1 was slightly better, but not even close to Win 10. This from a dedicated Linux guy (my XYL runs Linux Mint exclusively, as do most computers that I need to operate continuously with no reboots). I've been a Linux admin since 1995, so have worked with just about every flavor out there, including having been on most of the evaluation teams for DOS 5.0 and later, including Windows builds.
