[Elecraft] K3 with Heil HC-5
I bought a Heil HM-10-5 mic back in 2000 when I bought my FT-847. This is the original style that sets in a cradle stand. I chose the HC-5 element for good voice fidelity and always get good reports. When I bought the K3/10 I contacted HRO for the correct connector cable. Turns out that the standard Kenwood cable CC-1XLR-K, with the red connector is perfect for the K3 (HRO price $35.95). 73, Ed - KL7UW -- Message: 7 Date: Thu, 3 Jun 2010 18:49:12 + (GMT) From: John Lawrence j...@hughes.net Subject: [Elecraft] K3 with Heil HC-5 To: elecraft@mailman.qth.net Message-ID: 215460679.155598.1275590952889.javamail.m...@webmail01 Content-Type: text/plain; charset=UTF-8 I've settled down on the HC-5 as the best sounding SSB TX audio.

[Elecraft] K2 - first tests and some problems (serial no. 6905)
Hi there. I suspect this may be the first of many questions and requests for advice with my new K2... First test (K2 manual page 43) revealed that I had stupidly omitted the U2 6V regulator (thought missing from kit until today), so I got the 080 error message. Added this and did not get the 7100.00c display but 3030 with blinking A and RIT indicators with r above XIT and sometimes a - (dash) above that, depending on band selected. Scrolling though the bands gives: various 3040/3028/etc frequency readings with a 25023 and turn 1 and turn 2 appearing momentarily. The relays are clicking with band selection and the display seems ok, although I cannot get ST L 040 but ST L 003 and not INP HAND only INP SCAN One green bar at extreme right of S-meter. Shaft encoder rate/direction and battery volts/current display are ok. Are these related to firing it up first time without 6V U2? What should I check? Many thanks.

Ian, That sounds like either the menu system has gotten messed up or you have one or more soldering problems. I suspect that you may have attempted to change some menu items and do other actions when it did not work without the regulator installed. Since this is a new build, I suggest you do a Master Reset which will put all the menu items back at the default setting. Hold the 4, 5 and 6 buttons in while turning power on. then wait for the reset to complete. If that does not change anything, please let us know what you have accomplished and what you now observe. 73, Don W3FPR Ian Liston-Smith wrote: Hi there.

Re: [Elecraft] K2 ATU and 43-ft Vertical
Paul, the K2 internal tuner is a wide-range device and should be able to match the 43 ft vertical from 10 thru 80 unless you happen to pick an unfortunate length of feedline. The impedance seen by the tuner will depend on the feedline length. All of the available 43 ft verticals should work equally well electrically. Their mechanical construction and subsequent ruggedness will vary as will their ease of assembly and erection. I just use a 43 ft piece of AWG 12 wire suspended from a lightweight fiberglas Spiderbeam pole, and it works fine. Total cost should be less than $150, mostly for the pole. It cannot be emphasized highly enough that the performance of any of these antennas will depend almost entirely on the radial system used. Try for at least 32 radials, each as long as your space permits up to 65 ft or so. Other than the radials, the next best thing you can do to improve performance is to use a remote tuner at the base. This will eliminate most of the feedline losses you will incur when using the K2 internal tuner. I use a CG-3000, and it is okay. I would dearly love for Elecraft to offer a remote tuner, however!!Are you listening, Aptos ;) ? 73 Craig AC0DS __ 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] K2 ATU and 43-ft Vertical
Paul, That is not an easy question to answer, and for your particular case, we do not have enough facts. It would be necessary to know the configuration of the radial field for that vertical, then plug that information into an antenna modeling program to find the impedance at the feedpoint to the antenna for any frequency of interest. After that, you must specify the feedline (both the type, the velocity factor and the length), as well as the details of any matching network at the base of the antenna. It is not a simple question, and the right answer is maybe Once all that information is available, the feedpoint impedance at the shack end of the transmission line can be calculated. With the feedpoint impedance at the shack end known, then the L network values to match it to 50 ohms resistive can be calculated. A look at the specifications for the KAT2 indicate the maximum inductance available and the maximum capacitance. If the required inductance and capacitance for the calculated L network is less than the maximum values available for the KAT2, then the answer is a definite yes. A 43 ft vertical is a bit short on 80 (but not impractical). There was a recent article in QST with a tuner at the base of a 43 ft vertical to provide a good match on 80 and 160. A 43 ft vertical is a 43 ft vertical, and the major difference between them is the effective electrical diameter of the radiator, the mechanical construction, and the price - take your pick. There is no magic in the 43 ft. length except it is practical to erect without a large crew tugging on guy lines, many can simply be walked up. 73, Don W3FPR Paul Huff wrote: Does anyone have any experience with trying to match one of these 43-ft verticals, that are being offered by several manufacturers, using the K2s internal ATU?

Re: [Elecraft] K2 ATU and 43-ft Vertical
As Don mentioned, the 2-part article in QST was written by AD5X and can also be seen here: http://www.ad5x.com/images/Articles/Match160.pdf I built one of these matching networks (it's not a tuner) for my 43' vertical and it works very well on 160, 80 and up. The AD5X matching network is a very clever design and makes tuning of this short radiator quite easy as it offsets the huge capacitive reactance of these antennas and even allows control of the relays right over your feedline. Very slick. I have a Zero Five vertical and it is made very well, has been up about 3 years and still looks brand new. The only difference is that with the AD5X matcher I can tune it on 160 and 80 now! The feedline makes a huge difference primarily due to the loss that will impact your performance with poor SWR. If you have a lossy feedline (like RG8X like I used at first) the antenna will appear to match pretty easily. If you switch (like I did to 1/2 hardline, with its much lower loss) you'll see the impact of all of that capacitive reactance in making tuning of the 43' antenna very difficult especially on 160 and 80. In fact, I could not match it at all on 160. 73, Bob W5OV -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Paul Huff Sent: Saturday, June 05, 2010 5:20 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K2 ATU and 43-ft Vertical Does anyone have any experience with trying to match one of these 43-ft verticals, that are being offered by several manufacturers, using the K2s internal ATU?

Re: [Elecraft] K2 ATU and 43-ft Vertical
Paul: Wire works exactly the same as aluminum so don't get carried away with the shiny look! The S9 approach makes sense. A few wires lashed to the pole or inside the pole will do. 80m is where the need for lots of radials come in since 43' is considered short for that band. Spend the $$ saved on aluminum on a remote tuner. Coax will do ok except for 80m where the Z is very low and SWR high. The K2's tuner will do fine but on 80m there's a risk of excessive current through the tuner's torroids. I've burnt them up on low Z antennas before. Above 14 mHz, a 43' vertical develops a high angle lobe, straight up, and isn't considered good for DX but will work. An inverted L, 100ft long, would be a better antenna and cheaper!

Most of these verticals that I have seen are in the mid to upper $300 range, except for the fiberglass one from S9 Antennas. Any opinions on that particular antenna? Paul, I know power limits are not the problem with the K2 barefoot, but consider on 80 meters the base impedance of a fat 43 foot vertical with a modest radial system is about 12 - J 290 ohms. It would be worse with a thin wire. You would have to supply almost 1200 volts peak at almost 3 amperes to the antenna base to apply 100 watts on 80 meters. Since the 50 ohm SWR is over 100:1 on 80, it would be very difficult to get a significant percentage of your transmitter power into it on 80 (and impossible on 160) unless you put a real matching system right at the antenna. (and no, an unun is not a matching system and won't fix 80.) On 60 and 40 meters things are OK. SWR is under 6:1 so feedline efficiency would be OK without the unun. On 30 and 20 things are tough again, but far more workable than 80 and the unun at the base would help. Without the unun SWR is about 30:1. With the 4:1 unun maybe 8:1 SWR. Personally the only way I would have an antenna like that is if I remoted a good tuner right at the base. Otherwise I'd buy a trap vertical like a 6BTV or that Butternut vertical that actually has things that act like traps but that are not called traps by name. Overall, unless you put a tuner very close to the antenna, a trap vertical would work a whole lot better. For 80 you could base load the thing, and a 43 foot vertical with a good ground would be decent. Just make sure the antenna has a good base insulator, because at 100 watts you'd have over 1000 volts at the antenna base. DX Engineering has the best mechanical construction and a very good base insulator. 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
[Elecraft] SDR-IQ
Does anyone have the correct settings for the K3 to work properly with the SDR-IQ? I'm sure I've got something set wrong because when I connect the IQ to the IF and switch output the levels seem very low, I can see signals on 40 but they don't seem representative of what I am hearing and what the S Meter is telling me. When I switch to 17, I can't see any activity on the scope, but I can hear signals on the band. However when I connect the antenna directly to the IQ and set EXT Radio back to none, I am able to observe signals and tune them in on 17 with no problem. Thanks in advance.

Re: [Elecraft] SDR-IQ
Unless you have performed the IF Output buffer gain modification http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf or use the Clifton Labs broadband buffer amplifier between K3 SDR-IQ http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf what you see is entirely normal. The unmodified K3 IF output is approximately 17 dB lower than the RF signal input level. 73, ...

Re: [Elecraft] XV50 cooling
Gentleman, My promised temperature rise measurements will have to be delayed a bit. This XV50 has a bad power output module and I will have to wait for one to be sent from Watsonville. Later next week, I will have the data. BTW - Mitsubishi in their notes at the end of the data sheet suggest that the module case temperature should be limited to 60 deg/C - but that is too hot to touch (140 deg/F), so the excessively hot criteria may actually be well within the limits of tolerance - I would not want to hold my hand very long on a surface that is at 60 deg/C. Also, I do agree that other components can be affected by the temperature rise, but most are spec-ed at 60 deg/C, so in reality, there may be no problem, just a discomfort zone - details after the new module arrives. 73, Don W3FPR Don Wilhelm wrote: Eric, Have you actually measured the temperature rise? I am interested in just how much is excessively hot. While it does get warm, I have always found the temperatures to be well within spec for the output module. I have an XV50 here for repair right now. It is next in line for work, and I intend to get to it this weekend. After it is repaired, I will measure the temperature rise on the bottom panel right under the heat spreader. I have a Fluke 279 with a temperature probe available. Report on Monday. 73, Don W3FPR Eric wrote: I have a late-model xv144 with holes in both top and bottom panels, connected to k3 with milliwatt drive. It runs excessively hot at 10w out in digital mode EME when used one minute on one minute off, so i dont think just getting new panels will help you. I use a small muffin fan blowing air underneath with the xv-144 up on the optional tilt stand and this simple solution works great. I also use an xv-432 for eme at 10w but its internal fan keeps it cool. Perhaps if enough people request a retrofit kit with an internal fan for the xv-50 and xv-144 Elecraft would consider it. I'd pony up. The fan could attach inside the top panel. 73 Eric WD6DBM __ 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 Announcement
Good Evening, I returned from Seaside this afternoon after an interesting day at the local hamfest. I did not spend a dime but saw lots of folks I knew and met a few new ones. Two of them are moving away so seeing them will become much more difficult :( Lisa was as welcoming and cheerful as ever. It is always a treat to chat with her. I did not know she had her very own John Deere tractor. Greg was there discussing various modes on the K3 with many folks. It was fun to talk with him too. The weather from home to the coast only got nicer as we drove along. By the time we returned to downtown Buxton it was WARM! It was nice to feel the sun and not have to wear multiple layers of clothes to stay comfortable. Propagation was discussed as was building, contesting, and operating in general. I met my ECOM friends and got lunch from the NTS folks I have worked with. It pays to get on the air :) Hopefully I can help a few folks with their building projects and get them communicating. I proselytize the use of CW, make a few converts, and encourage the backsliders. However it does seem the wheat is winnowed from the chaff as they pass through the eye of the needle. Please join us tomorrow afternoon and 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 2200z (Sunday 3 PM PDT) 14050 kHz Monday z (Sunday 5 PM PDT) 7045 kHz Stay well, Kevin.

Re: [Elecraft] KDVR
The answer is YES. The first paragrasph of the KDVR3 Installation manual tells it all -The KDVR3 Digital Voice Recorder allows you to prerecord voice messages to be transmitted and to record received audio. The details are in the K3 Ownr's manual and the KDVR3 Installation instructions. 73, Don W3FPR N8XPQ wrote: I have competed K# build #4354 this afternoon.
