Re: [Elecraft] KPA 500 - and 50 Hz in Europe?
Hi Wayne and thanks for the info re KPA500 power supply The toroid transformer in the KPA 500 takes up most of the space available in the K3-sized cabinet and it is amazing that the developers managed to add a linear regulator and even a 500W amp etc. – hi! Now toroids are a bit hard on the inrush current and I guess some soft-start device has been provided for. But my main concern is this: Is the toroid rated in such a way that no saturation/overheating will occur with the European mains frequency of 50Hz? 73 Richard - Richard - HB9ANM -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA-500-tp5353688p5360567.html Sent from the [QRO] 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] Alignment and Test Part II
Brian, That is entirely normal. Which one of the 3 methods mentioned are you using to calibrate the 4 MHz reference? 1) Measure the TP3 frequency with an accurate external counter - adjust C22 until the K2 display matches the external counter. 2) Listen to the 4 MHz signal with another receiver - tune C22 until right on 4 MHz. 3) Just set the C22 trimmer slot to the midpoint. Actually a better method (greater accuracy) exists - wait until you have completed the K2 and you can receive 10 MHz ((or 15 MHz) WWV, then use the N6KR method. You can find the How-To on my website www.w3fpr.com article on K2 Dial Calibration. 73, Don W3FPR Brian Denley wrote: While doing the 4 MHz Oscillator calibration, CAL FCTR shows 12100.10 which seem nominal.

How? Try going to China as an individual company and pursuing a cease and desist suit. Or collect infringement damages. If a government is not watching your six, it won't happen. One reason to manufacture in China is to have control of the clones that are going to be made one way or another. You might be able to get it knocked off of eBay, but you'd have to complain.

I haven't priced the K2 and K3 recently but based on the last time I checked it out, a K2 with 100 watt output is about half the price of what it would cost (about $4000) to get a K3 with the features I would want.

Re: [Elecraft] New 2KW amp from the HB1A folks (YouKits)(PetrOurednik)
Anyone interested in electonics manufacturing should get a copy of Curtis, Philip J., The Fall of the U.S. Consumer Electronics Industry: An American Trade Tragedy. It has been known for a long time in the manufacturing industry that even if a manufacturer pays tooling and setup charges to have something manufactured in Asia, there is a very good chance the same product or component will be offered for sale direct through other channels. I have seen tooling paid for by US companies be used to make products that directly compete with the products that were tooled! Nothing can be done. The USA never has enforced any protection for manufacturers here, including dumping and patent infringement. That's really why we lost the consumer electronics industry in the 80's. Our government, at least since the 70's and especially 80's, has never considered manufacturing more important than short term money. Zenith and others won lawsuits for dumping, but our own government fought tooth and nail to prevent and delay enforcement. If we want to see what manufacturing we have left survive, we would have to change the attidudes of our consumers and our own government. Otherwise we just accept the fact that products can freely get ripped off. I expect to see more and more of this in the future. 73 Tom __ 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

There is a point where the imagination of the designers and primary testers is exhausted (HOWEVER productive that may have been) and only real customers in all their gawd-awful varying circumstances can come up with the typical breadth of complaints from the inane to wanting new features. This secondary phase and their positive and imaginative response to it (often omitted by Yakencom development) is what has made Elecraft into what it is today. So there is some sense to waiting out the secondary phase. With this company the product on the other side of the secondary development will be quite keen and effectively engineered by the masses for the masses.

Bill, GM0VIT wrote: Why is everyone so keen to be at the head of the queue? Surely it would be more sensible to wait until the inevitable teething problems have been identified and overcome. Sensible? Perhaps. However, one of the greatest points of puchasing Elecraft products is the on-going development that occurs after introduction. Usually, that doesn't happen at all with the big-box manufacturers. With Elecraft, having an early unit does not mean that you are stuck with what you bought. Their products undergo continuous improvement, based on real-world user feedback. I enjoy being part of that process. I ordered my K3 before there was such a thing. I waited 9 months for s/n 559 to arrive. (Earlier orders had to wait even longer.) Since then, There have been several updates and modifications that have come out that make it an -even better- radio than the one I bought. I have enjoyed performing every mod, and installing every upgrade. That's just me. Others may feel better waiting, and getting a later unit. That's fine too. You just miss out on the early excitement, and all the operating time on the new toy since introduction. In the Elecraft community, there's room for all. Some of us enjoy being early adopters. Here, we have learned that that can be a -good- thing.

Re: [Elecraft] headphones in phone jack makes meter go up ...
Was the nut on the headphone jack tightened sufficiently to make the washer behind the panel tight? If not, there is a possibility that the board is moving a bit when the headphones are plugged in (or removed) and may cause strange happenings. Squeeze the board and front panel metal together and snug up the headphone jack nut to strong finger tightness. 73, Don W3FPR Duncan Carter wrote: K3, S/N 3543 with a recently exchanged dsp board.

Re: [Elecraft] headphones in phone jack makes meter go up ...
It could but I don't think it's too likely. As far as misalignment is concerned, I think if you don't bend a pin and you carefully line up the pins and sockets and if the pins slide into the sockets freely as mine did, if there's any mis-alignment, there's a socket issue that's beyond my control. Elecraft has circuit diagrams available on-line and I've spent quite a few hours lately studying them. What I haven't seen are drawing of the circuit board traces which are common service information; having trace board drawings would really help in troubleshooting the problems. I could, of course, just send it to Elecraft but that's not very appealing to me. I've been a ham for fifty-five years and build, modified, ad repaired my own gear and other peoples. I've done repairs and managed service depots for industrial vibration equipment. One of the things that I've learned that if you send something with intermittent problems in for repair without knowing what is really wrong, there a good chance that you'll get it back without the problem really being cured. I also have a good collection of test equipment.

Re: [Elecraft] Status of the K2 world
I'm on my third K2. On the previous two I felt I had drifted away from radio and I sold them to reinvest the money into other things. On my third, last year, I realized that if I do radio at all the only ones to use were the K3 and the K2. I'll let everything else radio related go, but these two are just keepers. Right now the K2 is sitting in the living room connected to a Buddipole on the deck. Running 15 watts on 20. To me, the K2 will be both historic and a classic. 20 years from now, people will be looking back at the end of the last century at the K2 about the same way many of us who are older and licensed in the early 60's look upon the Drake TR-4c. I can't think of any transceiver that was more popular or more desired by my ham radio peers than the TR-4c. I can only hope that it is still in production. Or possibly and hopefully moved on to the K2-A or K2-B. The concept of the radio is unmatched anywhere else - a tiny, lightweight radio with performance comparable to vastly more expensive products - and you build it yourself from a kit. How cool is that?

I haven't priced the K2 and K3 recently but based on the last time I checked it out, a K2 with 100 watt output is about half the price of what it would cost (about $4000) to get a K3 with the features I would want. If I wanted all the K3 options the price goes up even more. I'm not active enough, or have enough disposable cash, to justify spending that kind of money on a K3 so I'm perfectly happy to keep my K2. __ 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 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] KAT3 tuning bandwidth
Hi, On 80 meters I did some tuning and when I try the SWR about 12 KHz lower the tuner produces an extra click and the SWR is terrible again. It seems the tuner remembers segments of about 20 KHz. Is it possible to keep the tuner in its tuned settings so it is not necessary to tune the complete band in 10 or 20 KHz steps? 73 's Steef PA2A, K3 # 4654 __ 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] headphones in phone jack makes meter go up ...
It may be that the problem is around/related to the RF gain pot. Check the traces/pins/sockets related to that. RF gain is a voltage across a pot, whose wipe, with a percentage of the high side voltage, is sent to an ADC to generate numerical advice to the MCU for RF gain. Anything that shorts or places an existing voltage on the wipe line other than that from the pot wipe could move the voltage indicating erroneously that you had set the RF gain back, and would raise the S meter reading. Even though this is a digital process, the analog behavior was retained of setting the S meter to where the signal would have to be to have signal engage AGC again. When the defect is in force, does the radio behave as if you had cranked back the RF gain to the point of showing that same S meter reading or does it still receive as if the RF gain were at maximum? 73, Guy.

Re: [Elecraft] KAT3 tuning bandwidth
If the feedline antenna combination is such that a 1.5:1 segment is only 20 kHz wide (a common enough occurrence) then one should take the time to get tunings up and down. You can probably do it in a couple of minutes. The K3 will shift seamlessly with your operating after that. One of the benefits. 73, Guy.

Being an early adopter of new products has several disadvantages and advantages. Advantages: - Bragging rights to others who don't jump as quickly as you. - Discovery of product capabilities and early start of learning curve. - Use and advantage of ownership of tool not available to others. - You have another TOY Yea!! Disadvantages: - You get warts and all... - High Potential of required firmware/software updates to clear operational and functional issues. - Possibilities of hardware mods to correct sub-standard performance.

Re: [Elecraft] KAT3 tuning bandwidth
Guy, I did another experiment: I tuned on 14.250, 1:1.2 is the result. On 14.240 the same tuning values are used and the SWR is still 1:1.2 From 14.239.999 downwards the SWR is 1:8.3 with other KAT3 parameters. Up to 14.299.999 the SWR remains 1:1.3 and from 14.300 it is 1:6.7. It seems that old KAT3 parameters on other antenna 's are remembered forever.

Re: [Elecraft] KAT3 tuning bandwidth
There are several solutions here... 1) Clear the memories for the band. Enter Config then go to KAT3 and press CLR. This will clear your current ATU memories for that band and 1 tuning will be used across the band but they will continue to be learned as you tune. 2) Download K3EZ. This is a simple application which one can find by doing a search. This application has a pane that will allow a user to calibrate the K3 to their antenna on a per band/antenna basis. 3) Manually tune in every ATU window. The ATU does stay put as you tune the VFO. Its settings are only updated when you've crossed memory region boundaries and you transmit. As soon as you transmit if you hear a click and the ATU icon flashes that means that the K3 has recalled a tuning memory for you. ~Brett (N7MG) On Sun, Aug 1, 2010 at 3:02 PM, Steef PA2A p...@xs4all.nl wrote: Guy, That works!

Last evening I perused the manual. This morning I was rambling through how it might be used in conjunction with my K3. Two questions came to mind that field testers and perhaps others might like to comment on. My favorite activity in amateur radio is RTTY contesting. Elecraft pictures of the P3 with the K3 shows it on the users right side of the radio. My thinking is it might be better on the left side as I use the mouse with my right hand and operate the radio with my left when RTTY contesting. It would seem the point and click and other functions on the P3 would be better accessed with my left hand than putting the radio on the right side and having to reach across with my left or move my right hand from the mouse to access the functions. I realize the side is an operators choice (I think) but I'm wondering if anyone has any meaningful experience or thoughts on the subject. That leads me to my second thought. My prior experience with a bandscope was with a ProIII. (It departed the shack several months ago.) To the best of my ability with it there was no way I could discern separate RTTY signals in a contest. Does the P3 have enough resolution on the more narrow bandwidth sweeps to discern separate signals in a contest or is just a big blurs as the ProIII. If separate signals are discernible in a contest is it possible to point and click on one with the P3, and perhaps with the AFC in MMTTY enabled, be able to near instantly work that signal? I realize there are most likely a lot of variables involved but the thought occurred to me the P3 might be able to add a new dimension to RTTY contesting for me and perhaps others. Perhaps I'm wishing for more than the P3 is capable of but constructive thoughts and ideas would be greatly appreciated.

[Elecraft] K3 CW bug-ettes
Hi! I've noticed some weeny bugs - or rather things that don't seem quite right to me - in K3 firmware v4.03, DVR v1.03: 1. The new QRQ QSK mode works nicely aside from the known limitation of no RIT. However, this limitation still seems to apply when I change from full break in to semi break in using the band/QSK button. I have to go into the menu and de-select the QRQ option as well to get RIT back. 2. When in SSB mode, I can send CW just by hitting the paddle but if I assert the PTT first (e.g. using my footswitch), the rig goes into TX but won't key. 3. In SSB mode, if I accidentally hit the DVR voice-box message replay button twice, or if it bounces, the second replay interrupts the first but there is an extended silent delay at the end after playing the message, before the rig drops back to receive. [In CW mode, the second press chains another message as expected, but there is no extended hang at the end.] These are so minor, they hardly qualify as bugs. Just quirks really. Features if you will. 73 Gary ZL2iFB K3 #2887 __ 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] Speaking of off-shore manufacture...
I've not been on the radio at an ocean beach (but have been to such beaches, should take a radio next time). Others with experience doing it may have better answers. I would use a quarter wave vertical suspended from a fiberglass mast (fishing rod would work depending on the band) with a bit of wire in the water as radials. From what I have read it works quite well. When I have been to the coastal ocean I was looking more to do swimming. If I wanted to play radio I would probably go with 20 M. 16 feet doesn't take that much of a pole for the vertical. Its not my favorite band because most of the time I am greatly inland and have the room for lower band dipoles. DX has never been a special interest for me but on a costal location could be interesting.

Re: [Elecraft] K3 CW bug-ettes
Vic, the method that I use is to tune with the main receiver to find the DX transmit freq. When I have the DX tuned in, I tap the AB button and the SUB button then turn up the AF gain on the SUB. Then I select my transmit frequency with the main receiver and make my call. It is very convenient and is my preferred technique for working split. If I have to call for a while to make my contact it lets me listen for other callers with the main receiver and try to find a good call frequency. This is my main reason for buying the sub receiver.

She kept some distance from me after that. 73, Fred K6DGW - Northern California Contest Club - CU in the 2010 Cal QSO Party 2-3 Oct 2010 - www.cqp.org __ 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 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] Elecraft CW Net Report for August 1st 2nd, 2010
Good Evening, The nets were interesting tonight. I had a persistent cough which made it difficult to send and receive code. The more I thought about the cough the more I coughed. So I looked out the window, viewed the very pleasant weather, and thought of something else. Some of the meds assist in the mind body split ;) Maybe it was due the simultaneous fever and chills. Luckily I am getting better as time goes by. Twenty meters was not very productive so I figured forty would be better. No, it was not. It was not very noisy either which was good. I saw a photo of the sun from 2001 in the latest issue of Sky Telescope. If I remember correctly that was during the second peak of the last cycle. There sure were a lot of spots! Maybe someday I can hear the bands during those conditions again. I would like to work some contacts on ten meters too. I've had them on six meters and fifteen meters but never once have I landed anyone on ten meters. I'll keep calling CQ and see what happens. On to the lists = On 14050 kHz at 2200z: N0TA - John - CO - K3 - 994 K1THP - Dave - CT - K3 - 686 K4JPN - Steve - GA - K2 - 1422 W8OV - Dave - TX - K3 - 3139 W0RSR - Mike - CO - K2 - 5767 W0CZ - Ken - ND - K3 - 457 On 7045.5 kHz at z: K6PJV - Dale - CA - K3 - 1183 N0TA - John - CO - K3 - 994 K6DGW - Fred - CA - K3 - 642 I know I was unable to work everyone calling me because I have received email from at least one person who tried and failed. However, I did work everyone I could hear. Nick, WB5BKL, sent me a listing from the reverse beacon which showed me getting out. He was called away due to family matters but could have worked me from TX. I'll keep trying and hope the sun perks up just a little more. Last night I was able to spot the thin triangle created by Venus, Saturn, and Mars. This grouping will grow ever tighter during the first week of August. Keep a look out for it about an hour after the sun sets. Venus is easy to spot and then Saturn and Mars pop into view to its upper left. Until next week stay well, 73, Kevin.

Re: [Elecraft] Speaking of off-shore manufacture...
Susan, one of the commercial verticals such as an AV-14AVQ or AV-12AVQ mounted on a pipe pounded in the sand with a few wire radials will work very well on the beach. The take-off over a long expanse of salt water will be great. Twenty in the day time will be the best band and forty at night if you want to battle the critters. A 43 ft. vertical would be a little better, but also might be a handfull to erect for you without help. The KAT-3 will tune almost anything. Good Luck!

Re: [Elecraft] K3 CW bug-ettes
The QRQ option works in semi-QSK mode as well. It allows you (or some machine!) to send clean code at higher speeds. I've noticed that without the QRQ option -- even in semi-QSK mode -- when the speed gets above about 35 wpm it starts to have timing issues. After about 45, it is really bad. ?? I'm surprised to hear that, Vic. I thought the QRQ+ thing was all about making the TX-RX changeovers as slick as possible for QSK, so I don't know how it would affect semi-break-in since the rig is mostly held in TX. I seldom send above about 32 or 34wpm though, so perhaps there's some issue at the high end that I just haven't noticed yet? 73, Gary ZL2iFB __ 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] K3 CW bug-ettes
It's easy to test. Just program a memory keyer (etc.) and crank up the speed. In my opinion it has to do with the CPU being busy.

Re: [Elecraft] Alignment and Test Part II
Don: I used a separate frequency counter but I did struggle with finding a suitable probe. Direct connection seemed to load down the circuit and change the frquency slightly. I ended up using a 10X scope probe. That seemed to work OK. I have read you writeup of the N6KR procedure and I will give bit a try and report back. Just in case a spent some time calibrating a couple of my receivers within a few Hz in case I needed to use that method. It's been a while since my Tek counter has been calibrated.

Which one of the 3 methods mentioned are you using to calibrate the 4 MHz reference? 1) Measure the TP3 frequency with an accurate external counter - adjust C22 until the K2 display matches the external counter. 2) Listen to the 4 MHz signal with another receiver - tune C22 until right on 4 MHz. 3) Just set the C22 trimmer slot to the midpoint. Actually a better method (greater accuracy) exists - wait until you have completed the K2 and you can receive 10 MHz ((or 15 MHz) WWV, then use the N6KR method. You can find the How-To on my website www.w3fpr.com article on K2 Dial Calibration. 73, Don W3FPR Brian Denley wrote: While doing the 4 MHz Oscillator calibration, CAL FCTR shows 12100.10 which seem nominal.

Tom W8JI said: If we want to see what manufacturing we have left survive I think you'd d**n well better want to see US manufacturing survive! An economy based on the financial products [aka snake oil] produced by the kids in red suspenders on Wall Street is a house of cards, a recipe for disaster. Nor can it generate enough worthwhile employment for the population. Future generations will look back on the outsourcing of US manufacturing jobs, the dismantling of a very large chunk of your economy for short-term gain, and shake their heads in amazement that the perpetrators were allowed to get away with it.

Re: [Elecraft] Alignment and Test Part II
Brian, Yes, a 10X probe on the counter may be necessary to prevent loading - that depends on the counter and its input impedance.. If you know your counter is accurate, that will got things right on frequency, but if you have doubts about the accuracy of your counter, use the N6KR method which relies only on the received 'Standard Frequency' signal. All other errors are compensated when using that method - it will produce the best dial calibration accuracy that I am aware of. For those who have questions about how to do the :N6KR method, I suggest you look at my website article on K3 Dial Calibration www.w3fpr.com or search the Elecraft reflector for Wayne's original posting of that method. All I can say is that it works very well, and I use it on a daily basis when aligning K2s. 73, Don W3FPR Brian Denley wrote: Don: I used a separate frequency counter but I did struggle with finding a suitable probe.

[Elecraft] [OT] '73' on the waterfall
On PSK31 some guys know how to transmit a sequence of tones to write a '73' or a smiley face on the waterfall. Does anybody here know what software they're using to do this? IMO it's a little corny, but I am curious.

[Elecraft] antennas for Susan
Susan Said: the antenna farm will most likely be vertical and located right at the shore line. What suggestions do you have for me to construct for antennas? I had very good luck with a Force 12 Sigma 5, a CENTRE-FED inductively loaded short half-wave vertical [i.e., a short centre-fed dipole tipped up on one end ] on the Bay of Bengal shoreline. It being a centre-fed half-wave, not an end-fed quarter-wave, I didn't have to worry about an efficient ground-plane,so no lossy radials, and on the shoreline of salt water it really got out. Very good reports with a K2 at 10w. It also fits into a gym bag. I think a Caribbean DXpedition also used similar antennas and K2s near salt water. eric VA7DZ -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. __ 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
