I just wondered if anyone got a suitable way having both Headphones and Monitor audio with a constant level on LINE OUT jack in order to record a 48-hour contest, for example? Setting LIN OUT to PHONES just does the trick but the RX audio level is controlled by the AG gain knob of the front panel which is really annoying in a Multi-Op Contest Team where nobody listen at the same level. Doing that way makes some part of the recordings quite low and some others distorting! I think lots of contesters would appreciate to have an option in the K3 for having the RCV and the XMT audios both with a fixed level on the Line output. 73, -- Olivier / f5mzn ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Isolation between Ant 1 and 2??
John King wrote: Has anyone else seen this crosstalk? Yep. I'm sure everyone that's tried it has. If so, what is considered acceptable? Well, that's harder to answer and entirely dependent upon your definition of acceptable. Clearly, the K3 wasn't designed to provide high isolation between the antenna ports - just look at the unshielded ANT1 and ANT2 leads in close proximity to each other. If they had been concerned about isolation, these runs would have been miniature coax (which you could easily install yourself.) In the scheme of things, though, the isolation isn't really too bad. Let's take your case: S3 to S9+20. That's 56 dB of isolation, which is about what one would expect from a typical commercial amateur radio grade antenna switch (pay no attention to the manufacturer's claims - I have measured them.) Isolation values of 80 dB and up are common in expensive commercial and military switches (Transco, Narda, etc.) So, it depends. I knew the port-to-port isolation in my K3 was going to be less than it could be when I built it. I though about installing RG-174 in place of the bare wires, but decided not to. I didn't see where it would buy me anything. All in all, I love my K3. I'm an engineer, and I've been on the air for over 40 years.

[Elecraft] Isolation between Ant 1 and 2??
Do not assume that this entirely due to poor isolation. Much of it probably is, but not all. I remember about 40+ years ago, hearing a friend on 15m on a dead band. He was only around 2 miles from, but he was really weak. I called him. Turns out, he was testing on his DUMMY LOAD. No second antenna port (his was a Galaxy V Mk II). Obviously, the dummy load was not total isolation. Or if it was, then the coax going to it was not. He was using a Heath Cantenna. How many others have had a QSO using their dummy load or were able to hear other stations while using their dummy load? How many have tried? An easy test would be to keep the DL connected and disconnect the other coax from the rig. Then calculate the difference. My K3s only have Ant 1, so not possible to try here. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: AW: [Elecraft] Isolation between Ant 1 and 2??
I would consider that figure acceptable. With my K3 the isolation between ANT1 and ANT2 is 42dB worst case, 56dB Max. Moving the single wires around made no difference. I suspect that the level of isolation is determined by the ATU PCB layout. Given the size of that board I think that the isolation obtained is reasonable. 73 Stewart G3RXQ On Sat, 3 Jan 2009 13:43:21 +0100, Koppendorfer Klaus wrote: yes isolation between ant1 and ant2 is very bad... if I have time I try to change the silgle wires from the rs323 ports to the atu-board to koax wires, maybe this will help a little 73 OE6KYG KX1 244 K2 1331 K3 115 -Ursprüngliche Nachricht- Von: elecraft-boun...@mailman.qth.net [mailto:elecraft- boun...@mailman.qth.net] Im Auftrag von Dick Roth, KA1OZ Gesendet: Samstag, 03.

[Elecraft] Re: k3 SWR readings seem generous
I always use 5W, ... when I tune up my external ATU. Actually, I use 15 watts for tuning both the internal K3 tuner, as well as my external MFJ-998 tuner. I do this for two reasons: 1) I get much better SWR agreement between 15 watts and full power than I do with 5 watts and full power, especially on the external tuner. 2) I figure that using a switching-type tuner stresses the 10-watt output circuitry of the K3 at 5-watts tune power (all that hot-switching). But at 15 watts, the K3 100 watt PA should have plenty of margin. It might be interesting to know what power levels Elecraft recommends regarding radio stress during tuning.

Re: [Elecraft] Re: k3 SWR readings seem generous
One thing I think would be really slick is to see a path in which someone can insert a watt meter such as the LP-100 into the chain between the output and the antenna tuner where it belongs.

Hot switching RF in an external ATU is not to be recommended for any radio at any level. BUT - you DO hot-switch your K3's RF output when using any relay-based auto-tuner, including the internal K3 auto-tuner. So my reasoning is that I'd rather hot-switch the 100-watt PA at 15 watts rather than the 10-watt PA at 5 watts. And then, my MFJ-998 (which I use with my ALS-600) reads SWR more accurately at 15 watts than it does at 5 watts, so when I go to full power the tuned SWR is still minimum. As Wayne stated earlier, SWR readings at low power may be less accurate due to the detector diode voltage drop at low power.

Dick Green WC1M wrote: Recently, there was a post on the FOC reflector to the effect that the FT2000 is a superior choice to the K3. Much of the criticism of the K3 centered around the size and heft of the rig, as well as the cost. In that message he referred to the K3 costing $3300. Where did he get that mistaken idea? The beauty of the K3 is its modularity which does not force me to pay for unwanted options like AM, FM, ATU (I use a tuned input amp and resonant antennas), General Coverage RX, etc. An unassembled K3/100 with KXV3 and a 500 Hz filter costs $2050. The FT2000 has a minimum 3 kHz roofing filter which actually has been measured at ~5 kHz by Sherwood and others, so I could subtract another $100 for the 500 Hz filter to be more comparable (i.e. the K3's 2.7k vs FT2000's 5k) but I don't want the absolutely terrible BDR and IMD performance of the FT2000 that would result so I left that in. Add a KRX3 and another 500 Hz filter and you have $2750 for the *only* rig on the market with True Diversity using two high performance receivers. Having used diversity for ~6 months now I will never have another rig without it. Duplicating all the whistles and bells of the FT2000 would make a K3 cost more, but I much prefer unexcelled performance to unnecessary whistles and bells. IMHO the choice between a K3 and FT2000 amounts to a basic intelligence test, and this guy failed the test.

[Elecraft] K4: I am not Surprised
The latest thread about the K4 is very interesting to read. Right on track, users, owners, operators are looking for the next big thing. The paint is hardly dry on the K3, and now we are talking about a K4. I remember this same type of threat with the K2. I am surprised it took this long to develop. I agreethis K3 is the best rig I've ever ownedthat includes the Galaxy IV, HW100, FPM300, SB102, TS820, TS830 (good rig), TS850 (good rig), IC765 (good rig), IC746 (bad rig), FT1000MP (good rig), IC756PROII (OK), K2 (great rig) and then the K3 (best rig).

[Elecraft] K3: Still unable to set power correctly in DATA A (sigh)
I recently installed the latest firmware and ran the TX Power calibration wizard - nice work. However while running WSPR (a sound card data mode) I was somewhat annoyed to find the K3 power meter showing about twice the output power I had selected. Checks using my own power meter confirmed that the K3 is putting out about twice the amount of power specified by the power control when DATA A is used (though the exact difference seems to vary a bit from band to band.) Using TXG VCE is NOT the answer, as the output power in SSB (and in CW) is regulated correctly. Using the maximum TXG VCE -3.0dB I still can't quite get the power down to what it should be, but if I do that, SSB output is too low. Forgive the note of frustration but I am frankly very annoyed and fed up that after all this time and numerous reports of this issue from me and several other people going back several months, the K3 is still not capable of performing a simple basic function like regulating the output power to the level the operator requests. I am seriously considering selling the K3 at this point, as I am losing confidence that Elecraft has any intention of fixing this issue. - Julian, G4ILO.

Re: [Elecraft] K3: Still unable to set power correctly in DATA A (sigh)
I can report the identical problem to that which Julian describes. I don't remember the firmware version where this started but it was certainly not always the case that the actual power output in Data A mode was so much greater than the requested power. I can set for 5W and get a displayed (K3 meter) output in excess of 10W. No problems at all with the other modes that I have tried.

[Elecraft] KRX3 Install Problem: Extra Standoff, Front Panel Board
I am in the middle of installing the KRX3 in my K3/100 (s/n 1152), and have bumped into a stopper. I am at the point of re-mounting the main DSP board to the front panel board. I find that there is a metal standoff mounted on the front panel board near J31 which is in the place that the newly-mounted nylon standoff (same length) is mounted on the Main DSP board. This standoff is attached to the Main DSP board in the KRX3 instructions at the top of page 17. Has anyone else run into this? Can I remove the nylon standoff from the Main DSP board and leave the metal standoff on the Front Panel board in it's place? It looks like there are some components on the Main DSP board near where the top of the metal standoff will rest. I **really** don't want to remove the front panel board from the front panel assembly to remove the metal standoff, especially without explicit instructions. I'm sure that there are a screw and lock washer behind the between the board and the front panel, so unscrewing the standoff is a crapshoot of whether the parts behind will come out with some shaking. I've placed a photo of the metal standoff on the Front Panel board online at: http://www.k8nd.com/FrontPanelStandoff_3489.jpg 73, Jeff K8ND ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K4: serious challenge for the $10K toys
Of course there is a fast way of developing a big radio. Just take the current electronics and put them in a bigger case. My Orion II is a good example. There is a LOT of room inside. But a bigger case does not make a better radio in my opinion. As for the idea that a higher price indicates a better radio or an institutional quality radio, there is the Yaesu FT 9000 example. That very expensive rig is subject to recall to replace almost all of its innards and I don't believe that has been accomplished yet. So much for design reliability. I have no doubt that Elecraft could design a radio for the institutional market if it chose to do so but I'll bet that market has its problems as well. As for the 7800 that appears to be quite capable and I'm sure there are institutional users, but for critical missions, I bet the choice is more likely the radios from Rhode Schwartz or Harris which are way beyond the price points we are accustomed to. By the way, commercial users tend to look for the lowest priced, dependable equipment which will get the job done. Globe Wireless uses TenTEC receivers for computer controlled, unmanned remote locations. If they weren't dependable 24/7 workers, I doubt they would be used. They are far from the most expensive but they apparently meet the needs.

The requirements from institutonal users could be different from hams. Durability, physcial strength and easiness of operation could be another areas to look into. I fully appreciate that Elecraft is a very clever manufacturing engineer and marketing manager. When you examine both K2 and K3, for all the non-essential parts (including the fat head and pan head cabinet screws), I am rude to say that they use the cheapest materials. For the T/R switch of KPA100, they only use the cheap IN4007 diodes for the switching (but works very well!!). On the other hand, for the criticial parts such as the front end of XV144 they use an excellent MOSFET. Elecraft is very clever in a way that they can mimize the production costs against performance. K2 and K3 are excellent in specifications but I doubt whether they can really operate under full institutional usage 7/24 a week. May be there is another version of K3 for institutional users which I don't know. I am an ICOM user as well. I understand that ICOM earns huge revenue from the institutional version of their IC7800, IC7700 and ICR9500. For a purchase of 10k or over, the prospective purchaser will look into other issues. For me, I would also think of resell value of my used gears if I invest 10k or more. May be I am lucky that in Hong Kong, all the top gears (except K3) are only 80% of the US prices. Therefore, when I sell my IC7800 or IC7700 in future, the loss to me could be minimal. With the clever minds in Elecraft, I think they have the capability and talent to enter the profitable institutional market. Perhaps, they may go for IPO in due course (of course not now) for funding. cheers, Johnny Siu VR2XMC --- 2009年1月3日 星期六，DOUGLAS ZWIEBEL doug...@gmail.com ��道�s 寄件人: DOUGLAS ZWIEBEL doug...@gmail.com 主�}: [Elecraft] K4: serious challenge for the $10K toys 收件人: Elecraft Reflector elecraft@mailman.qth.net 日期: 2009 1 3 星期六 上午 10:57 Hi Joe... Yes, I'm sure a K4 (or how about a K88 so the SE Asia guys would buy in big time) could be easily made. In fact, for that group, it might make sense to price it even higher than theirs...say $15 or $20k. You know, when you get into the upper tiers of any market, it's the HIGH PRICE that convinces folks that it's good. And if it really is good (as I'm sure the K88 would be), then bingo. Tons of profit marginwith a concomitant lower volume. It all balances out. However, if you look at the track record of Elecraft, they appear to be very good at identifying very tiny niche markets (although the K3 seems to have a wide appeal...wider than expected?). Somehow, competing head to head with a big radio doesn't seem to fit the Eric/Wayne approach. As I recall (it's probably on their web site somewhere), the K3 was targeted to be a high performance, very portable, light weight radio...with some very neat features too. They have certainly achieved that. If I were them (which I am not), I'd be focusing on refining what I have (which they are obviously doing). It is probably just a matter of time before the FT9009 and IC7878 come out, using nearly identical receiver design approaches to those used in the K3 (and Orion).

[Elecraft] Using K3 Utility for two K3s
As a long time ham, I have owned many rigs like most of you here. I got my K3 about three weeks ago and very impressed with, so much so I will be selling a rig and buying another K3 with a bit different configuration than my current K3 to use here but also, mainly, to use at a second QTH. I really would like to try diversity reception and my other QTH is perfect for that -- a lot of acreage for various other receiving antennas. My question is simple, I think. Can I use the K3 Utility on my computer for firmware updating of two K3s? I am guessing the Utility will differentiate the two radios due to different SNs and it just looks at what firmware it has and what updates are available for each radio. But I am wondering if different folders on my computer will be required to store the update information via the Utility program. Also, is it possible to upload the configuration I have for my present K3 to the second K3 that I am seriously considering? --- well more than considering -- have just about made up my mind to get the second one. The 7700 will be looking for a new home. Thanks and 73, Greg K2UM ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] Using K3 Utility for two K3s
Yes, you can use the K3 Utility on your computer for updating of two K3s. Two K3s was indeed the motivation for displaying the S/N. You don't need two different sets of firmware folders, they are input to the K3 Utility and their content does not depend upon whether you have one or more K3s. The configuration save capability creates a default filename that includes the serial number of the rig whose config parameters you're setting. If you don't replace the filename presented in the save as file dialog, all of your configuration files will indicate which K3 they were saved from. The folder you choose for configuration files can be changed, but it would be inconvenient to do this every time. I thought it would be easier to use one common K3 configuration folder for all your K3s, and use a filename prefix (like the Serial Number) to differentiate the files. This is part of why the default configuration file names are so long. They include the rig's serial number as well as the date and time it was saved. You probably wouldn't want to save a configuration from one radio and restore it into another. Part of the saved configuration is the rig-specific calibration data (synthesizer as well as Tx Gain). 73 de Dick, K6KR From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Greg Buhyoff Sent: Saturday, January 03, 2009 9:09 AM To: elecraft@mailman.qth.net Subject: [Elecraft] Using K3 Utility for two K3s As a long time ham, I have owned many rigs like most of you here.

RE: [Elecraft] why the K3 is my favorite rig
And while we're on the wish-list for a follow-on rig, let's add: A contest-grade keyer. My biggest disappointment with the K3 is a built-in keyer that I can't use with contest software. (It speaks very well for the radio that this rather minor issue is my biggest one.) This left me with the alternatives of serial port keying or an external keyer. Serial port keying I find undesirable for reasons that have already been hashed out several times on the reflector. So I bought an external keyer. Hint to Elecraft: It's already been done. Don't reinvent it. Drop a Winkey chip in the box and be done with it. 73 and thanks for listening Carl WS7L K3 #486 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Re: k3 SWR readings seem generous
Phil, There is a huge electrical difference between switching an additional inductor in series with the load (or a capacitor in parallel) than what is commonly seen as hot-switching which results in the amplifier seeing an open circuit until the relay closes. A very high RF voltage will exist if the PA is operated into an open circuit. During the tuner's tune cycle, the load is never open circuit to the PA, and the resulting RF voltage is kept under control. 73, Don W3FPR Phil Debbie Salas wrote: Hot switching RF in an external ATU is not to be recommended for any radio at any level. BUT - you DO hot-switch your K3's RF output when using any relay-based auto-tuner, including the internal K3 auto-tuner. So my reasoning is that I'd rather hot-switch the 100-watt PA at 15 watts rather than the 10-watt PA at 5 watts. And then, my MFJ-998 (which I use with my ALS-600) reads SWR more accurately at 15 watts than it does at 5 watts, so when I go to full power the tuned SWR is still minimum. As Wayne stated earlier, SWR readings at low power may be less accurate due to the detector diode voltage drop at low power.

RE: [Elecraft] K3: Still unable to set power correctly in DATA A(sigh)
I can report the identical problem to that which Julian describes. I don't remember the firmware version where this started but it was certainly not always the case that the actual power output in Data A mode was so much greater than the requested power. I can set for 5W and get a displayed (K3 meter) output in excess of 10W. No problems at all with the other modes that I have tried. So? Reduce the power you request to get the required output. What other radio has a calibrated power output control? The wattmeter in the K3 is relative ... there is a documented power vs. frequency slope. Testing seems to indicate there are also nonlinearities with changes in peak to average ratio and as the power level moves away from the calibration points. The directional coupler in the K3 does not have the high level of directivity and compensation of a product like the Telepost LP-100 nor does it have the high quality detectors.

AW: [Elecraft] K3 KPA3 bias adjust
Locate the BIAS pot at the front of the KPA3, between the heat sink and the KPA3 shield. Note what the display current is in the VFO B readout when you tap the Display button and turn the VFO B knob to the current readout. In RX, it should be 1.0A or so. In XMIT (not TUNE), it should be about 1.90 to 2.0A when the Power knob is set to 12w or above so the KPA3 is made active (but there is no RF output since XMIT is used). Or you can press the PTT button but do not speak. If there is much more current than this, set the BIAS pot to minimum (fully counter clockwise). Then tap XMIT (not TUNE) and note what the current is in VFO B's readout. Slowly turn up the BIAS pot until you see 400-500mA more current that was seen with the BIAS pot at minimum. 73 OE6KYG KX1 244 K2 1331 K3 115 -Ursprüngliche Nachricht- Von: elecraft-boun...@mailman.qth.net [mailto:elecraft- boun...@mailman.qth.net] Im Auftrag von Jan Erik Holm Gesendet: Samstag, 03.

Re: [Elecraft] Re: K4: serious challenge for the $10K toys
Cookie, you have a point! The thing that frustrates me perhaps the most about my Orion II is its size. It's huge! It doesn't fit well on my operating desk (every other rig I own does fit), and it's just plain murder to position it efficiently from an operating standpoint. Ten-Tec could have made it much smaller (not as deep) without sacrificing any of the front panel space. My K3, on the other hand, fits just about anywhere. I even think the ergonomics are better, not worse. An Orion II has about 1350+ cubic inches of volume. The K3 has just over 400 cubic inches. So, theoretically you can fit three K3's into an Orion. I'm not sure what Ten-Tec was thinking of when they designed the Orion package, but obviously convenience wasn't on their mind.

[Elecraft] Re: k3 SWR readings seem generous
There is a huge electrical difference between switching an additional inductor in series with the load (or a capacitor in parallel) than what is commonly seen as hot-switching which results in the amplifier seeing an open circuit until the relay closes. A very high RF voltage will exist if the PA is operated into an open circuit. During the tuner's tune cycle, the load is never open circuit to the PA, and the resulting RF voltage is kept under control. Don - Maybe my hot switch term was not accurate for this situation. I think of hot switching as making sudden abrupt impedance changes at the output of your radio or amplifier. In any case, it seems to me that it would be less hard on the radio if you do this at 15 watts on a 100 watt PA vs 5 watts on a 10 watt PA. But then, I could be wrong.

Re: [Elecraft] Re: k3 SWR readings seem generous
Phil, It is perfectly OK to do that, but I believe you are being more conservative than necessary. The KAT3 is designed to 'take it' and the PAs of the K3 (either high power or low power) are also - if that were not the case, there would be a big warning statement in the manual. In general, Elecraft designs are on the conservative side and will withstand normal operating without stress. 73, Don W3FPR Phil Debbie Salas wrote: There is a huge electrical difference between switching an additional inductor in series with the load (or a capacitor in parallel) than what is commonly seen as hot-switching which results in the amplifier seeing an open circuit until the relay closes.

Re: [Elecraft] K2 What mods during assembly?
Jeff, All the mods that have an 'official' Elecraft blessing are included in the K2 kit already. There is also a large list of other 'special purpose' mods that one can add - for instance one can order the board for my K2 Fixed Audio Output from Tom Hammond N0SS (www.n0ss.net), or you can build and add my CW PTT for the K2 if you have need for that. Many others are in a similar classification - determine your needs and pick and chose accordingly. One thing I do on a KSB2 build that I would recommend is to ground the crystals on the sides, near the base - it is not difficult if you plan the order of mounting the crystals with this in mind and mount the crystals one at a time, then solder the ground wire. 73, Don W3FPR W7BRS wrote: As I wait patiently for my K2 kit to arrive I am wondering if the list could chime in with opinion about what mods and/or options are best to install DURING initial construction of the K2?

Re: [K3] [Elecraft] Constant Level Line Out with Monitor
Hi, I hate to be a wet blanket, but having to listen to myself in the headphones in order to be able to record the transmitted audio is very tiring. I do not normally have Monitor on while operating. May I suggest another toggle feature whereby the Monitor output can be directed to phones/speakers, line out or both? Another alternative would be to have a separate line out level for RX and TX audio and leave the Monitor function out of this.

Re: [Elecraft] Re: KBT3?
Several years ago I displayed a product at a trade show. Although we had working prototypes we did not have a pretty model to put out for the show. Using a timer chip, some LEDS, a building brick , nice silk screening and a snazzy case we allowed customers to pick it up and heft it. We received lots of physical comments such as Say, you must have a lot of parts in there. The working ones were secured to the table so the customers could verify the product worked. Elecraft continues to prove that perception is NOT reality. My K3 should be here in 2 weeks. I am more excited than a ham with 47 years on his license should be! I congratulate Elecraft for a well thought out and implemented product line. 73, Sid K3SX - Original Message - From: WILLIS COOKE wrco...@flash.net To: wayne burdick n...@elecraft.com Cc: Elecraft Reflector elecraft@mailman.qth.net; DOUGLAS ZWIEBEL doug...@gmail.com Sent: Saturday, January 03, 2009 3:29 PM Subject: [Elecraft] Re: KBT3?

Re: [Elecraft] K3: Still unable to set power correctly in DATA A (sigh)
There's a thread on a related topic (PSK TX IMD) on the Elecraft K3 list at Yahoo Groups. Rich VE3KI posted some measurements done with the PSKMeter that show poor IMD above about 50W. I've suggested he re-run the tests with a 3dB pad to compare apples-to-apples and reduce the effect of non-linear response in the PSKMeter, but Rich has suggested that perhaps the peak power is exceeding 100W when the TX PWR setting is above 50W. Your observations would seem to confirm that. Leigh/WA5ZNU I recently installed the latest firmware and ran the TX Power calibration wizard - nice work. However while running WSPR (a sound card data mode) I was somewhat annoyed to find the K3 power meter showing about twice the output power I had selected. Checks using my own power meter confirmed that the K3 is putting out about twice the amount of power specified by the power control when DATA A is used (though the exact difference seems to vary a bit from band to band.) Using TXG VCE is NOT the answer, as the output power in SSB (and in CW) is regulated correctly. Using the maximum TXG VCE -3.0dB I still can't quite get the power down to what it should be, but if I do that, SSB output is too low. Forgive the note of frustration but I am frankly very annoyed and fed up that after all this time and numerous reports of this issue from me and several other people going back several months, the K3 is still not capable of performing a simple basic function like regulating the output power to the level the operator requests. I am seriously considering selling the K3 at this point, as I am losing confidence that Elecraft has any intention of fixing this issue. - Julian, G4ILO.

In auto info mode, the K3 sends data to the connected program whenever you change frequency. The insertion of the commands is because somehow you've managed to trigger my diagnostic spew.

[Elecraft] K4: How to escape the niche?
What niche? Back in olden days, someone would use ain't bottom to refer to a patch of land up aways from the river, a kind of pejorative. Until, that is, somebody figured out how to grow corn on it. The parallel perjorative for Elecraft and its customer base would have been tinkerers and kit builders, and cranky and hard-to-please if reading the reflector email, true enough at some point for about all of us. Definitely anathema to the short term high leverage model all the rage these days. Niche from them is just a one word summary pejorative. I'd be more inclined to refer to the Elecraft user base as grown from a niche. The run-up to K3, the K2's, K1's, etc, and the word of mouth user/contributor network, the foundation for launching the K3, wasn't just laying around to be discovered. It was grown and tended, same way one grows an orchard from seed. The way one turns tinkerers and kit builders, and cranky and hard-to-please into loyal contributors and users is a long-term intentional responsiveness that allows user input a voice in setting company directions. The high-end technical part takes some serious high end talent on the Elecraft benches. Arguably one can find that in a lot of places, including Kenicaesu. But practically speaking, the Elecraft high-end expertise includes a significant high-end technical segment in their user base, a segment that is ever growing via the kit method, fix it yourself, modify forever culture amplified with the internet email and reflector networking. Niche just isn't technically accurate any more. Other manufacturers may mimick the technical advances (I hope they do), but most are completely confused or turned off when it comes to understanding the networked, interactive, constributory nature of Elecraft's users. We had four K3's at NY4A for CQ WWDX CW. No one is looking back to MP's or Orions. The lone Orion owner in the crowd was satisfied that the K3 was at least as good as his Orion, He had no trouble driving the K3, whereas in prior contests the Orion drove rest of us to distraction tripping up on the menus. Nothing but the real stuff could unite that crowd of technical discordants on a single radio. I don't really care what Kenicaesu does, just so long as their new offerings don't have key clicks or splatter. I know that it will be a very rare day when an email I send to their headquarters is actually read with some intention of dealing with its contents. JA1MP has passed on and, sadly, some kind of spark at the top went with him. As to a K4, or better, K3+ should be a box of the same height and depth and style as the K3, with a width TBD (5 or 6?), that has an LCD screen (4x3 touchscreen like Garmins, etc?) as it's front. It should contain an aux computer sufficient to do the functions of panadapter and whatever else might be useful. It should be able to contain an Elecraft switching power supply for the K3/K3+ combo good for full RTTY transmit output. It should be able to be bolted to one or the other side of the K3, by removing the K3 side cover and replacing it with the uncovered side of the K3+, making it into a seamless single unit. The method of constructing the K3 should make this easy. Or it should be able to be set separate with its own side panels. The enclosure itself would allow the extension of the K3 style case for projects in the same fashion as K2 owners have used the EC2, while allowing K3+ ready-built combos for the less adventuresome. 73, Guy ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] EU source of components for small K3 mods.
Over the last few years, the UK and EU have benefited from the exchange rate when purchasing Elecraft equipment, but our Pounds or Euros now buy far less Dollars. This makes the purchasing of small components for K3 mods from Elecraft somewhat expensive. Also, because of export overheads, it is burdensome for Elecraft to ship small orders overseas, so with Wayne's blessing, a UK business is offering to supply some items for K3 owners in the EU at very advantageous prices. For example, a small component kit including the exact items for the K3AFMDKT, which also includes parts for Larry Phipps' suggested IF output to panadapter mod. (plus a couple of spare SMTs), is available posted to UK addresses for £3.50 or posted to EU addresses for £4.00. The kit designation is K3MODKIT#1 and a number of K3 owners in both the UK and EU have availed themselves of it already. Other components e.g. for the Synth. ALC mod or the AF output mod are available individually on Mode Components' website, in SMT or leaded versions, so can be added to the order for a few pennies. Parts not appearing in the component listing can be obtained and added to the list in a day or two. See Mode Components website at http://www.modecomponents.co.uk Chris, who owns Mode Components, maintains a considerable library of spec. sheets for active devices and supplies copies with purchases as a matter of course, if he has them. If you don't see what you want, drop Chris an email to sa...@modecomponents.co.uk. You may find yourself pleasantly surprised, especially if the parts are made from Unobtainium HI! Components are always carefully and appropriately bagged before shipping. His turnround is fast and PP charges are very fair.

[Elecraft] Ranking Rigs
I think to rank rigs for any one person the operating style or what are the most important goals are necessary to consider. This isn't a weird thought, but often overlooked. One friend adds to this does it feel good? Good point. My main interest is CW with SSB decreasing as time moves on, but the digital modes increasing in interest. Once it was about contesting, both phone and CW. Interest changes and where MOMT/MOST was the thing years ago it's more single bands now and with lower power. DXing has been and still is my main interest and particular weak signal DX. remembering the sun doing it's thing or not doing it's thing, hi. So I'll give an example from my prospective and the technology is time related as we all know even in the near term. 1-10 with 10 the top. BTW, reliability is always high on any of my lists. Service is important and Ten-Tec/Elecraft are the best in my opinion. Recall everything breaks in time! IC-765 = 7.5 IC-756II = 6 or perhaps a 5. I hear ProIIIs are much higher from folks I trust. FT-1 = 7.5 a few years back, but a great rig. FT-1000MP = 8 FT-1000D = 7.5 FT-950 = 7.5 Omni VI+ = 8.5 Omni V = 6 TS-480 = 7 Orion I = 9 (Latest version) Super radio Orion II = 9 Omni VII = 8.5 K2 = 8.5 K3 = 9.5 The K3 is super sitting beside the Orion. Congrats to Elecraft. Finally, I truly believe our country has the best and innovative technology and not slamming other countries. I'm biased, but take a look at the numbers above.. who makes them? This is not just radios, it's everything but keeping in mind this country is a product of many other folks from all over the world. My opinion of course.

[Elecraft] FS: Elecraft MD2 microphone
Very nice condition, I was using it with my K2 but now use a MH2 with it because it's smaller and easier to move around for portable, etc. The MD2 was made by Heil and is in a stainless steel case. It works as is with the K3, just turn on the front panel bias on the K3. I do not have a desk stand or clip for it, just the mic and cable built in to hook to the K2 or K3. Asking $79 + $10 for Priority mail shipping + insurance. Prefer Paypal or US postal money orders only. The Elecraft and Heil lettering is fine, there is some wear on the M in MD2 on the back of the mic Can provide pics for those seriously interested.

[Elecraft] Elecraft CW Net Report for December 28th 29th, 2008
Good Evening, At long last I have reassembled this computer and its OS. It now has all the bits (no pun intended) necessary to collect and disseminate email and run the database software for ECN's log. The computer which was hosting everything while this computer was having fits is now under the weather. I swapped DIMMs in and out and moved them to different banks. Seems like they have some form of dementia. When I next get into Hillsboro I will buy it a few new DIMMs and see if that sets it right. Either that or try some castor oil ;) The weather has slackened from its depths of winter attitude. After calling the ARES EC who called the county Emergency Manager who called the EM of the Land Use and Transportation, I finally had my road plowed! What a miracle :) Then, after Charlie the grader guy helped me out with his trusty grader Margaret Ann I was able to move off Buxton Lookout Road for the first time in ten days. Just before Charlie and Margaret Ann appeared I was busy in the shower enjoying the wonderful feeling of luxurious, hot, running water! Oh WOW! After hauling water for five days and heating it on the wood stove a hot shower was like another miracle! As I drove out I got to the junction with Bacona Road and noticed only one lane was available for travel. Next, I saw a truck approaching so I backed carefully onto Buxton Lookout Road to let them pass. I saw they had an official plate as they stopped. So I got out of my truck and wandered over to meet Al (who I found out later is KL7EF), a representative of the Oregon State Police. He wanted to know the status of my road. I told him the grader could only get a little past my house before he bogged down. I knew Al wanted to go to the repeater tower and knew he was interested in the generator's fuel supply. I told him he could not get there with his truck but would need snow shoes. At that point I mentioned I was an amateur radio operator and had had to work from my emergency power for the last 102 hours. I also mentioned I was affiliated with the local ARES group and with MARS. Then he told me his callsign. So we chatted for a while as the snow kept piling up around us. I knew from his call that a little weather like this was not a problem to him. I also found out he was a 99% CW op. Now who said that code was dead? Hah!!! I got to meet another very fine gentleman from Alaska. On to the repaired lists = On 14050 kHz at 2300z: W0CZ - Ken - ND - K3 - 457 W0JFR - John - CO - K3 - 994 W1TF - Ty - GA - K3 - 696 WC7S - Dale - WY - K2 - 4360 N0SS - Tom - MO - K3 - 008 NO2D - Pete - CO - K3 - 2126 JH1VIG - Kaz - Japan (near Tokyo) K6DGW - Fred - CA - K3 - 642 AC7AC - Ron - OR - K3 - 004 VE7XF - Ralph - BC - ?

W0JFR - John - CO - K3 - 994 The weather turned to rain for much of the last four or five days so the snow melted to about one foot in depth. Then we got another foot of snow yesterday and more is falling presently. I am hoping to get a chance to repair one of the broken HF antennas but have not been able to get it to move from its frozen perch. The other one is also immovable, stuck lower down than intended with a branch wrapped in it. That was the one I used last week and subsequently to run my HF rigs. Tomorrow it will get used again in its bowed but not broken state. Hopefully there will be a day of thaw to loosen the guy lines so both antennas can be dropped and repaired. Then they will be able to get back on the air in a more proper configuration. Until tomorrow stay well, 73, Kevin.

[Elecraft] Elecraft CW Net Announcement
Good Evening Again! Not much has happened since I last wrote you :) Snow is still falling, the computers are working, and the fire is still warm. Oh, yes, Sam is still guarding the fire as he sleeps. I am still trying to find a time where propagation is better for us. I moved both nets an hour earlier last week. That helped a lot on twenty meters but did not help the forty meter net at all. I have been informed I was easily heard prior to the net but as it started signals faded quickly. So I am going to move it another hour earlier to 5 PM PST or 0100z. Hopefully this time will help others find the net. I will see if I can make and eat dinner between the nets but it may be a tight squeeze. Pat used to make dinner for me and ask about the folks I had worked in the early net as we ate. Now I get all the chores and no company. Eating after the nets is not an option. As the seasons change I will move the net times once again but for now they will be at 2300z and 0100z. Please join us tomorrow evening. 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP relay help) Sunday 2300z (Sunday 3 PM PST) 14050 kHz Monday 0100z (Sunday 5 PM PST) 7045 kHz Stay warm, Kevin.

[Elecraft] Summary K2 What mods during assembly?
Thanks everyone, on both sides of the Pond. Let me quote part of what I wrote. On Sat, 3 Jan 2009, W7BRS wrote: [..] But browsing the Elecraft website for the copious mods out there for the K2, I began to wonder if there was better sense in putting in _some_ of the critical/important mods to the RF/FP board during initial construction. I was trying but failing to zero beat on mods. I differentiate a mod from an option. An Option, in my book is first an Elecraft accesssory with a Elecraft Part #. Prime Grade A Option. That's just my twisted logic. Next in line under Option I could accept a User-designed board/procedure that adds capabilities and functionality. Again, a reproducable change that comes in the form of a product, board, or well tested procedure that adds functionality or capability. After that the word Option dissolves into a muddy sense of whatever you like. Now, a Mod, to me is a modification, a hack (good sense of the word), a kludge (crufty sense of the word), work-around for a known problem and as a side effect may provide a simple benefit but above all else is not an Option. The only benefit expected minimally is to resolve a performance or technical issue with the Stock K2 or Official K2 Option. The target of a Mod is the K2 or any of the K2 Options. As far as Mods go, I think Don cleared up that all the Mods are already in the Kit. I think that answers the main question I had. There are some Mods I've been told about that I will double-check on when I get the kit. I will check out the Rework Eliminator as a possible First Option.

RE: [Elecraft] K3: Still unable to set power correctly in, DATA A(sigh)
The point is it was providing the correct power output levels before the last couple of firmware revisions. Something changed that made it go from putting out approximately the right power level, to putting out WAY TOO MUCH (i.e. causing splatter) power. Not true ... in spite of careful calibration at both 5 and 50 watt levels neither of my K3s has ever produced exactly the power requested on any band other than 20 meters, on any mode other than CW and at any power other than 5 or 50 watts. The variations can be as much as 3 dB on SSB depending on the peak to average ratio of the driving audio and amount of compression used. Setting a power control calibrated for CW and expecting that level to be accurate for PSK31 or any other arbitrary digital modulation is complete folly and utter hubris. Among other issues the wattmeter does not know if you are setting peak or average power and it does not know what the average power should be for the arbitrary data and arbitrary modulation. For the K3 to accurately control the power level in all modes the its directional coupler would probably need to be improved by at least an order or magnitude. The response flatness would need to be improved by at least an octave and the detectors would need to be substantially more linear ... and that's just for CW. To handle arbitrary audio inputs takes some knowledge of the peak to average ratio as well as the peak duration (duty cycle) in order to select the proper detector time constants. Every voice every digital mode and every arbitrary data stream will have different peak to average ratios and duty cycles. Do you expect the DSP to calculate those values on the fly? Perhaps the power metering should be derived from a DSP based spectrum analyzer? Accept the fact that the power level control is relative. If Wayne and Lyle can improve on it that's great. However, trying to hold .1 dB or even 1 dB accuracy from 1 mW to 120 W, 1.8 MHz to 54 MHz with arbitrary modulation sources in a reasonably priced amateur transceiver is a fool's errand. 73, ...

Reduce the power you request to get the required output. What other radio has a calibrated power output control? The wattmeter in the K3 is relative ... there is a documented power vs. frequency slope. Testing seems to indicate there are also nonlinearities with changes in peak to average ratio and as the power level moves away from the calibration points. The directional coupler in the K3 does not have the high level of directivity and compensation of a product like the Telepost LP-100 nor does it have the high quality detectors. If you want a bloody laboratory grade meter, buy a laboratory grade power meter. The point is it was providing the correct power output levels before the last couple of firmware revisions. Something changed that made it go from putting out approximately the right power level, to putting out WAY TOO MUCH (i.e. causing splatter) power. Setting TXG VCE to -3 dB gets DATA A output almost to where it should be, but of course adversely affects SSB. This is NOT about the accuracy of the wattmeter, its about overdriving the PA. 73, Steve AD7OG K3 #1544 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3: Still unable to set power correctly in DATA A(sigh)
Rich VE3KI posted some measurements done with the PSKMeter that show poor IMD above about 50W. The K3 wattmeter is essentially an average responding device. PSK31 has a relatively high peak to average ratio ... as much as 6 dB or more depending on the particular data but generally running at least 3 dB at idle. Since the KPA3 will clip at an output power much above 110 watts, indicated power output on PSK31 idle should never exceed 50 watts with 30 to 40 watts being a safe value. I've suggested he re-run the tests with a 3dB pad to compare apples-to-apples and reduce the effect of non-linear response in the PSKMeter, but Rich has suggested that perhaps the peak power is exceeding 100W when the TX PWR setting is above 50W. I've made similar measurements to those of VE3KI using a soundcard and software detectors on a separate receiver while monitoring the K3 power output with a factory calibrated LP-100. In fact, the K3's peak power output is around 110 watts when the indicated (average) power is about 50 watts with PSK31 idle modulation. Increasing the power output simply results in extreme overdrive of the KPA3 (and/or the IPA since I did not make separate measurements below the 12 watt level). The excess drive results in a higher average power output due to clipping in the amplifier chain. The clipping results in greatly increased IMD products. Similar sets of measurements should be made for EVERY digital mode - particularly modes that use phase shift and/or multi-tone modulation. Every one of those modes will have unique peak to average ratios and duty cycles. Increasing the power output beyond the point of peak clipping (more specifically the 1 dB compression point) will, at best, only cause IMD and interference to other users and will, at worst, result in decoding errors in reception. Since the K3 power control is based on average power and not instantaneous (absolute) peak power, the power level (both requested and reported) can not be relied on as a gauge of proper operation unless the user knows with certainty how much headroom is required to handle the peak power without compression or clipping. 73, ...

Rich VE3KI posted some measurements done with the PSKMeter that show poor IMD above about 50W. I've suggested he re-run the tests with a 3dB pad to compare apples-to-apples and reduce the effect of non-linear response in the PSKMeter, but Rich has suggested that perhaps the peak power is exceeding 100W when the TX PWR setting is above 50W. Your observations would seem to confirm that. Leigh/WA5ZNU I recently installed the latest firmware and ran the TX Power calibration wizard - nice work. However while running WSPR (a sound card data mode) I was somewhat annoyed to find the K3 power meter showing about twice the output power I had selected. Checks using my own power meter confirmed that the K3 is putting out about twice the amount of power specified by the power control when DATA A is used (though the exact difference seems to vary a bit from band to band.) Using TXG VCE is NOT the answer, as the output power in SSB (and in CW) is regulated correctly. Using the maximum TXG VCE -3.0dB I still can't quite get the power down to what it should be, but if I do that, SSB output is too low. Forgive the note of frustration but I am frankly very annoyed and fed up that after all this time and numerous reports of this issue from me and several other people going back several months, the K3 is still not capable of performing a simple basic function like regulating the output power to the level the operator requests. I am seriously considering selling the K3 at this point, as I am losing confidence that Elecraft has any intention of fixing this issue. - Julian, G4ILO.
