Re: [Elecraft] K3: KPA500 vs XYL
Hi Guys, None of those XYL blandishments would work with my beloved of over 48 years married life. At the time we got engaged, I gave her a string of pearls. She asked me, How much did they cost? I should have recognised the warning signs then. Several years ago, we were in Sorrento in Italy. I took her into a jeweller's store and told her that as I was getting on in years, she could have any ring in the store (within reason) that she fancied. She told me that she would rather have the money in the bank in case she had to put me onto a nursing home. Still, she cares for me, she really does.

[Elecraft] K3V - another new product speculation
Having just stuffed another few options into my K3, with predictably gratifying result, my thoughts naturally go to what the next step might be. Let's see. P3: would be nice, but when I had an LP-Pan I hardly used it. Also: no room on the shelf. KPA500: Again, no room unless I decided to retire my full power amp. I could make room by retiring my spare rig, a TS-570S, which would make room for e.g. the KPA500, but I like to have a spare HF rig, as any rig can fail. I could retire my 2m ssb/cw rig, an ancient TR-9000 and replace it with an Elecraft internal transverter, but that unit seems too much like an afterthought designed for the casual user. When it comes to weak signal VHF/UHF I would like to see an architecture that supports remote preamps and separate feedlines for receive and transmit. Also on the possible wish list: a full set of VHF/UHF bands and sophisticated support for satellite use. I could replace the spare HF rig with a dedicated VHF/UHF multiband rig with satellite capabilities and no spare HF capability (or at least not a very good one). The new product suggestion: A new main branch on the K3 tree of options. I would replace the spare HF rig with a K3/10, and Elecraft would make a new set of internal 2m, 70cm and 1296 transverters that could all be mounted internally, taking up the space otherwise used by 2nd RX, 100W PA, tuner. These would be high end transverters, with the very best flexibility of antenna hookups, killer firmware support for satellite, etc. Disclaimers: I have not thought about how the module interconnections would work, and I might not buy this stuff on day one, but on the face of it, it would solve some problems. I would have a far better HF backup rig, and great capability on more VHF/UHF bands.

Re: [Elecraft] New product suggestion
Dave and company, What Dave says has been standard manufacturing practice for decades. Companies produce what they are best at and purchase power supplies at prices considerably lower than they could equal. Elecraft is a designer of first class RF equipment but there are others out there who are producing excellent switch mode power supplies in volume quantities. These firms excel in power supply design as Elecraft excels in RF design. The consumer gets a less expensive and superior product with the advantages of both firms expertise and economies of scale. A built in power supply does have advantages but of course it will add to cost. Most of us already have power supplies so why add to the expense. This might be especially true with export product. We can purchase a basic K3 and tailor it to our desire over time as resources allow. Meanwhile Elecraft concentrates on the RF side as no one else does. Please, I do not wish to rain on any ones parade. All of us have our pet desires for the Elecraft line. In some instances we come to realize or accept that there are some advantages to the approach taken by Elecraft as in small box design rather than large box design. Viva Elecraft and viva this forum. You are all a good lot putting forward ideas. I am no doubt as wrong in stating these sentiments as I was in questioning the need for the KPA 500, mea culpa. Life is good we are Elecraft users. 73 Doug EI2CN --Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of David Gilbert Sent: 09 April 2011 06:00 To: d...@w3fpr.com Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] New product suggestion I wasn't in any way suggesting that Elecraft should do such a thing.

Re: [Elecraft] understanding screw sizes
Pf, Most of the screws in the K3 are #4, and the thread size is in turns per inch (4-40). These are standard sizes here in the US - no metric size hardware is used in the K3 as far as I know. You have the reference link correct. There is also some #2 hardware used in the K3 - it is the smaller diameter, and has 56 threads per inch (2-56). #6 hardware has a larger diameter and will have 32 threads per inch (6-32) The length of the screw threads will change depending on whether the head is flat or not. For flathead screws, measure the entire length of the screw including the head. For the others, measure from the head to the end of the screw. The washers are designated by the size of the hole. Other dimensions may exist if important, but often just the hole size and the washer type (flat, internal tooth lockwasher, split lockwasher) suffice for the description. Sorry for those in Metric Land who do not understand the US hardware system. We tried to go metric many years ago and failed. Most of the auto industry is now metric, but for small hardware, the US sizes predominate here. We have to keep two sets of wrenches if we are to have a complete set. 73, Don W3FPR On 4/9/2011 1:51 AM, Pierfrancesco Caci wrote: Hello, while lenght of the screws is given in the manual in mm also, I'm trying to figure out how to read the screw and washer diameters that are given as 4-40 and such.

Re: [Elecraft] K3 - new product demand
INTRO: I am a past K2/100 Kit (fully fleshed out--the K2, not me) owner, and a present K3/100 FB owner, with also the XV144 outboard unit. Also in the stable is an ICOM IC-910H. The K3 6 meter section is fleshed out with a TE0552G, and the 910 works into a TE1452G. So I have 100 watts on HF and ~300 on 6 and 2 meters. The 910 also provides 432 MHz, but at lower wattage. It also has a serious hearing problem on 432, and I use a GaAsFET preamp on the mast at the antenna. This is more or less a stable station configuration for me. I would guess that it may be my last, but perhaps in 3-5 years I would be willing to contemplate upgrading... Now: IF'N I had to do it over again, and was faced with some new or nascent Elecraft choices, e.g. the KPA500/KAT500, a built-in 144 and 432 section with at least transverter drive power, what would I choose? WOULD NOTS: ]I definitely WOULD NOT choose the KPA500. 500 watts is just too much for HF, unless one only operates SSB or AM. I WOULD NOT choose the P3 -- for most of my operating, the narrow FLDIGI window of 4 kHz or SpectraVue is quite adequate. I definitely WOULD NOT choose an internal power supply. WOULDS: IMHO the 100-watt K3 is just fine for HF. I have never found a CW pileup I couldn't work through (it is just a matter of patience and timing). My gain comes from a proper antenna. I WOULD choose an internal 20-25 watt level for 144 MHz and 432 MHz. Especially at 432, IF a power level of a few hundred watts were the target, construction/design techniques are enough different that they would add substantially to the volume of stuff in the K3 box. 20-25 watts is plenty to drive simple 13 dB (20X) post-amps...barring spectacular openings, IMHO the requirements for effective communication at VHF and UHF are somewhat higher than at HF, probably simply because there is more of a tendency to use voice modes. Because of line losses, at 432 MHz one is probably better off with a mast-mounted GaAsFET preamp. I think that ICOM faced exactly this question with the 910H, and answered it by producing just such a companion unit. There is a problem with the GaAsFET preamps in the TE Systems amps...they are not protected in any way against high power RF, and I roasted my 144 MHz preamp with output from my 6 meter set-up (mea culpa). SUMMARY: I think the K3/100 with ATU and interface is simply the best rig I've ever owned. It does marvelous QSK, and with FLDIGI and the SignaLink-USB it does a superb job with other digital modes. I wish it had internal provisions for 20-25 watt output at 2 and 3/4 meters. The internal ~9 watt units are just not enough, and the 144 MHz K144XV unit I installed did not work properly anyhow. (That issue was admirably met by Elecraft; I was not the only one to have trouble with this unit, which has already been adequately discussed on the reflector.) I have no techno-lust for the KPA amp (leave it to 'phone ops) or the P3. WRT 432 MHz, it is looking like we may lose that band anyhow, to ill-thought-out incompetent governance (more's the pity). This has taken the edge off my interest in 432, even though I have 50 watts to a big Yagi on the band. Thus, for a plain-vanilla ham like me, 160 through 2 meter coverage would be nice...power levels as mentioned above.

[Elecraft] Yet another product idea
Several years ago at the Elecraft stand in Dayton I saw a prototype 1500-watt solid state amp. At the time I understood from the folks there (and maybe from some e-mails) that it had been built using some high-power transistors made by a company in Oregon (I think) with which K4XU is/was associated. I was told a couple of years ago that the K3 project had superseded the amp, because of the much larger potential market. But now I'm wondering... To what extent does the KPA-500 share design and/or hardware with that prototype? Might it be feasible to build and sell a 1500-watt amp for something approximating three times the cost of the KPA-500? Now *that* would tempt me, even at over twice the cost of an AL-1200, for the fast bandswitching and the quiet power. -- 73, Pete N4ZR The World Contest Station Database, updated daily at www.conteststations.com The Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com, spots at telnet.reversebeacon.net, port 7000 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] K3 - ARI500 and ALS600
Hello all. I have the above configuration. I have been trying for months now to get all of them to talk. I had Ameritron check my cable and test it, they say it works. I sent them just recently the ARI , cable and ALS. They tested all and say it works. I have been working with Elecraft and purchased the KXVA and the board with the pullup installed. I tested the cable and based on my measurements the voltages are on the right leads going into the ARI500. The link light is on solid when it is plugged into the K3. I do not hear the ALS600 switching when all 3 are hooked together and the rotary switch is in remote. When the ARI switch is in the on position the K3 will key the amp but NO power makes it through the amp. When it off, I get power through the amp, but no amplification. The cable was built by me, but checked twice by Ameritron. The only way I can get power out of the amp is take the ARI out of line and plug back in the keying cable form the K3. Any suggestions or questions. Any help to make the K3-ARI-ALS to all work together would be appreciated. Has anyone else made this setup work??? -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-ARI500-and-ALS600-tp6257078p6257078.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Oops K1 Dead!
Don, thanks for the info. I just lifted one end of D19 from the board and indeed it is a dead short. I powered up the K1 without the band module installed and it powered up fine, so that indeed is the problem. Since I am so D*n stupid, I don't think I'll use the K1 without the Zener installed. It looks like changing out Q7 would be a MUCH bigger deal, so now I'll go on the hunt for a 1n4753 locally -- maybe at RF Parts in San Marcos. Thanks again.

[Elecraft] Problem with K3 receive audio
I owned and assembled a K3/100 about two years ago and was impressed with the high quality of the radio, its design and support from other owners and Elecraft. Everything about it worked fine except that it seemed that I could never quite adjust the sound of a person on SSB to the point where it was a pleasant, (what I call) mellow, armchair-type copy. It seemed too shrill, it had a high edge to it that couldn't be adjusted out. At first, I thought there was something in a menu setting or a control I was using incorrectly that wasn't allowing me to add more lows (if that's what you call it) that was causing the problem, but that wasn't the case. I called Elecraft and talk to people about it, but no cause could be found. I kept it for about two months then sold it. Years have gone by and I am still very impressed with the quality of your product and company and would like to put together an Elecraft Shack. I am wondering if the changes that have taken place over the past few years in the programming of the K3 might have solved the problem I experienced a few years ago or maybe it is just my level of hearing that is the problem. Does anyone remember experiencing something similar with your K3 or heard about a possible solution?

Re: [Elecraft] Problem with K3 receive audio
The K3 has wonderful arm chair audio. Even though you can adjust the audio in the menu, I use a S/W program K3_EZ that can set up your K3 without going in the menu. You can set both receive and transmit audio. I also run the K3 through an amplifier that feeds two great book case speakers mounted on the wall pointed at me. That's for SSB and AM. I use head phones for CW. I've owned mine for 4 years and wouldn't ever trade or sell it. Just ordered the KPA500. Get another and be pleased every day. Licensed 62 years.

I kept it for about two months then sold it. There have been changes to the DSP board to allow more lows (remove a low frequency roll off) with low impedance headphones and a high cut filter has been added to remove noise from the digital to analog converter above 4.5 KHz. Those changes may help your perception of the receiver audio but I believe what you were hearing was the flat response of the K3. Unlike just about any other receiver I've tested, the K3 has an absolutely flat response 100 Hz to 4 KHz other than ripple in the first IF (roofing) filter. Other receivers show a pronounced roll-off starting between 1000 and 1500 Hz - between 3 and 6 dB per octave. Does anyone remember experiencing something similar with your K3 or heard about a possible solution? It is quite easy to create that warm sound with the K3. Simply use the RX EQ to duplicate the roll-off you are used to hearing. Setting 1600 Hz to -3, 2400 Hz to -5 and 3200 Hz to -6 warms up the receive audio nicely. Use -6/-10/-12 if you want an even more mellow sound. 73, ...

Re: [Elecraft] understanding screw sizes
Hi Pete, Well sort of... The tank and some Amal carb stuff did but the bike itself had BSC (British Standard Cycle) threading. It was based on Whitworth thread angles but was a fine thread system that most of were 26tpi. Then of course there are your BA (British Association) threads that were used for small screws on the electrical items. These were actually based on old French metric threads, not Whitworth That is how it was even on my 1st, a 47 Ariel.

Re: [Elecraft] Proposal for Mono-band Elecraft
Here! Here! I'm totally with you on that one. Size is an issue for me. While KX1 is small, I want smaller. While on this subject of mono-band qrp transceivers - having built almost everything in the Elecraft catalog multiple times (3 x K2, 2 x K1, 3 x KX1), I was wondering if anyone had some ideas on a beginner's complete homebrew transceiver. My knowledge of radio electronics is strictly hobby level. But, I'm really anxious to try building something from scratch.

Re: [Elecraft] K3V - another new product speculation
Kevin, for me personally it would be a plus to have HF 10W in there as a backup to the main HF rig, but it wouldn't have to be a mandatory ingredient. It could be another option along with the various VHF/UHF bands. Why, if we were to lose 70 cm (let's not be pessimistic and assume that we will) then someone might want to get the HF 10 W option to take its place in the box. Also, lots of hams start out from the VHF/UHF side and add HF as they upgrade licenses. If I were in that situation, a K3V/U would look a lot better than say an ICOM 910H because I wouldn't have to get a whole new rig for HF. Of course, I'd be looking at the rigs that have all the bands from the start, but the K3V/U would not have the compromises inherent in those rigs, and by starting with only say 2m and no HF, the price might not be too bad. I think it all comes down to the question: Are those beginners educated enough to understand the huge advantage of having a K3 base platform compared to say an IC-746? 73, Erik K7TV -Original Message- From: R.

Re: [Elecraft] K3 - new product demand
100 watts to 500 watts is ~7 dB, or just about an S-unit. 7 dB is the difference between a dipole and a tribander. Clearly there has been a super amount of interest in the KPA500, and just as clearly, 1500 watts and a 6-element beam at 90 feet will work to rule. This argument has been made and remade so many times it is as bad as republicans vs democrats. I wish Elecraft all the best, but it is just not my choice to go this route.

[Elecraft] K3V - another new product speculation
Satellite use was the major impetus for producing multi-mode multi-band VHF/UHF radios in the 1990's. The cost for launching ham satellites has rendered putting up anything but small FM repeater sats beyond reach ($10M), so the demand has dropped. When the FT-847 came out in time for Oscar-40 (AO-40) many eme'rs jumped to the FT-847 (as did I), but now I am switching to a superb HF radio (the K3) combined with the best transverters I can afford (and that is not German-made). Like power supplies, USB converters, and a lot of other items it may not pay Elecraft to get into. The only new HF/VHF/UHF rig to come out lately is the new IC9100 ($4K) and time will tell if that was a smart marketing decision. I will have about the same investment with my dual-Rx K3/10 plus 144 and 432 transverters. I would not bet on the IC9100 coming even close. I am convinced that SDR will take over the ham market in time. So direct-conversion 144 and 432 SDR may come along (several 144 SDR are under development at this time). I would say the K3 with transverters is a find approach (except maybe in a mobile/portable situation). You can have your K3V/U: just install a K3 with 144 and 432 xvtrs in a big box! Actually, the XV144 and XV432 are not very big so one should be able to make a common rack or container that is not much larger than the K3. So you already have the means to make a K3V/U for those that want it. To me this is smarter marketing (modular approach). Look at the architecture of many multi-band radios and you will see that they use a common IF with transverters, internally. Keeping RF and IF leakage down is a major problem designing such animals! 73, Ed -- Message: 3 Date: Sat, 09 Apr 2011 10:29:48 -0500 From: R.

Re: [Elecraft] Proposal for Mono-band Elecraft
Doug, I would suggest you adopt the Ugly Construction or Manhatten Construction methods to put it together. I would also suggest you look at the design of the SWL-40, it is one of the better mono-band ones IMHO, because it uses a superhet receiver rather than the more common DC receiver. A long while back, I participated in the MH-101 construction project, which was a 30 meter transceiver teaching project under the guidance of Chuck Adams K7QO. It was based on the SWL series (with Dave Benson's blessings). If you can locate the archives of that project, it might fit your desires. OTOH, Jim Kortege K8IQY is the King of Manhatten Construction, who designed a good 40 meter transceiver using only 2Ns. You can see this on his webpage at http://www.k8iqy.com/qrprigs/2n240/2n240page.html.

Re: [Elecraft] Proposal for Mono-band Elecraft
For a homebrew rig, I would recommend looking at the recent QST articles by W7JI describing his 40 meter receiver and transmitter. I believe they were in the Feb and April 2011 issues. Just finished building the receiver, and it works quite well. Fairly easy build with all parts inexpensive and readily available. I built mine Manhattan style using a RF proto board. Easy alignment and fairly good performance. As a RX, I'd rate it slightly inferior to a K1, mainly due to lack of an AGC loop. But it does have an audio limiter that partially addresses this. If you do go that route, make sure to check the ARRL website and feedback for the latest corrections.

Re: [Elecraft] K3 - new product demand
Purely from a VK perspective: Many times we hear stations from the US calling DX with their beam heading to VK. Whilst their signal is in the S7 - S9+ we answer the call only to get reports of S2-S5 with QSB. We are then proudly told they are using 'Legal Limit' and a 3 element tri-bander at 50ft. Now VK3MO is in Melbourne with a stack 5 over 5 over 5 over 5 Yagi's on 20M with 200W and is told he is 59+ almost every day. From what I have heard emphasis is placed on having a signal report of 59 or better and the high output amplifiers are increasingly being used for a one way signal and a lot of us forget about improving our own receive abilities. With a legal limit of 400W in VK, many of us 'creep' up the power with HF amplifiers and of course we all say we are running 400W so the RF policeman is happy...he knows the truth of course...but leaves us alone providing we do not interfere with 'other' users. The argument will go on for eternity is my guess. From purely my perspective and now experience, I am finding the KPA-500 has done a great job for me this past month. I have worked into EU and the US and during many qso's I turned the KPA-500 to bypass and collected reports. My focus was NOT on signal strength, but rather on the copy and I paid attention to those that I had to repeat myself to better get a handle on how my signal was doing. The results have been as I expected, the KPA-500 gave me what I needed to work DX that I could hear 55 to 58...I work on the assumption that if the signal I am hearing is 'good copy' then with the 400W we are legally able to use I should be able to work that station without too much difficulty. The DX station suffering QRM from nearby frequencies is going to have that issue no matter who he works and either they need to move frequency or improve their station receive capability.I hope the readers on this list do not take my comments to heart as I do not mean everyone, just that I am hearing more and more distorted signals than a month or so ago as propagation has improved and to some degree the signal quality can be altered by not paying attention to the adjustment of the transmit audio to ensure a clean signal. I have received some really excellent reports on my signal and of course this makes one proud. To be told your signal is superb does give one a swelled head...:-) To compare the KPA-500 @ $2,000 against a PW-1 here in VK at $8,000 is perhaps unfair but the reality is that is the price we have to pay in VK. As a portable operation I am unable to 'carry' a huge amplifier due to space and my ability to lift it becomes a huge issue also.

Re: [Elecraft] Problem with K3 receive audio
Should point out that the TX and RX EQ feature came later on as a firmware upgrade, but I would definitely agree that post DSP board upgrade and RX EQ, you can make it sound like anything you want, including shrill for the contests. The K3 is the only RX that I have ever had that can receive music on SSB and have it sound normal. And no, we are definitely not used to flat response. There have been MANY improvements since it was introduced, almost entirely customer-requested. SDR rocks. 73, Guy.

There have been changes to the DSP board to allow more lows (remove a low frequency roll off) with low impedance headphones and a high cut filter has been added to remove noise from the digital to analog converter above 4.5 KHz. Those changes may help your perception of the receiver audio but I believe what you were hearing was the flat response of the K3. Unlike just about any other receiver I've tested, the K3 has an absolutely flat response 100 Hz to 4 KHz other than ripple in the first IF (roofing) filter. Other receivers show a pronounced roll-off starting between 1000 and 1500 Hz - between 3 and 6 dB per octave. Does anyone remember experiencing something similar with your K3 or heard about a possible solution? It is quite easy to create that warm sound with the K3. Simply use the RX EQ to duplicate the roll-off you are used to hearing. Setting 1600 Hz to -3, 2400 Hz to -5 and 3200 Hz to -6 warms up the receive audio nicely. Use -6/-10/-12 if you want an even more mellow sound. 73, ...

Re: [Elecraft] Problem with K3 receive audio
Fred, Do I need to upgrade the DSP board? I added the lowpass filter but did not do a complete DPS board upgrade. My headphones, including the CM-500 are all high enough impedance that I don't notice any significant low end loss (I set the 50 Hz and 100 Hz bands to -16 dB anyway) so I could not see any benefit to a change. The DSP board makes no difference in speaker or Line Out audio so if your headphone impedance is about 150 Ohms or so, I would not worry about the change unless the high frequency DAC leakage is a problem. 73, ...

Re: [Elecraft] understanding screw sizes
Regarding machine screw sizes, American Standard. Screw numbers start out at o which has an OD of .060 inch. Each successive number has .013 inch added to it to arrive at its OD. Thus a number 1 screw has an OD of .073 inch, a number 2 screw has an OD of .086 inch, and so on . Hope I presented this well.

Re: [Elecraft] Problem with K3 receive audio
I found that the upgraded board removed a harshness which I always thought sounded like distortion, and this in spite of my reduced hearing at those frequencies. I think it actually does some more that is not alluded to by Elecraft. My guess is that the low end change is involved in some level of distortion improvement. Most people are very happy they did the mod. Swapping the board and sending the swapped out board back to Elecraft is really fairly easy. But don't order the board until you're ready to do the work and send the old board back promptly. The swap board is an Elecraft personnel refurbished board that someone else sent in. That allows them to run the program without making stocking decisions. 73, Guy. On Sat, Apr 9, 2011 at 5:41 PM, Fred Jensen k6...@foothill.net wrote: My K3 is #642. It sounds fine on SSB.

At the time I understood from the folks there (and maybe from some e-mails) that it had been built using some high-power transistors made by a company in Oregon (I think) with which K4XU is/was associated. I was told a couple of years ago that the K3 project had superseded the amp, because of the much larger potential market. But now I'm wondering...

But my forecast for next week has more snow in it and no sun. We need to enjoy those few sunny days we get. It was a busy week this week so I only got on the air once. Propagation was so so on twenty but as I examine Space Weather I see the sun is quite active. I also read about 10 and 15 meter openings with 20 meters being open almost all day long. It is nice that the solar doldrums are over. The next few years should be fun. If anyone is interested in acting as a relay station on either net please email me. I will turn the net over to you for a few minutes so you can call areas in my skip zone. It sure would prove helpful to those I cannot reach directly.
