[Elecraft] K3 - ERR BP1, XV3, AT3, IF1
Jim (KG0P), These error displays sound similar to ones I get from time to time. Remove the front panel and carefully clean all the connector pins. Then apply some connector lubrication before replacing the panel; we have some stuff called 'Contralube' over here. An added benefit is that you no longer need to get a screw driver in the square slot to remove the front panel next time. It comes off using just fingers and thumbs. I have to carry out this procedure once every year or two. On later model K3s, I believe Elecraft used connectors with gold flashed pins which resolved the problem. 73 Tom G3OLB __ 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] External Speakers for K3
I have a great radio speaker made in the 1950's by the National Radio Company. 11x12x8 inch metal cabinet with 9-inch diameter speaker (no amplifier). K3 sounds very nice with it (I also have a Sony stereo headset when I need to hear even better). CM500 sometime in my future. The current HK computer speakers used with the KX3 will be replaced by a West Mountain amplified speaker which is immune to RFI (my wife is using a pair on her desk top to eliminate my RF). If Elecraft ever considers it, a generic K-line cabinet would be desirable for making a pretty station. One could install whatever in it. No need for a speaker, power supply, and several other accessories that are obtainable anywhere. 73.

[Elecraft] W1: adapting for high-power
I need an internal wattmeter for a homebrew project. Except for the fact that the W1 only takes up to 140W without modification, it looks like a great solution. I'm thinking about using a surplus bridge from an industrial ISM generator and padding the DC output by 12-dB before feeding (via miniature coax) to the junctions at D1/R3 and D2/R4. Can anyone think of a reason that this would NOT work? Also, if I simply change the voltage at TP1 by adjusting R17, does the entire power range follow, or does the accuracy suffer at one end of the range or the other?

[Elecraft] Choosing End Fed Wire lengths for multi-band portable operation
I have frequently seen postings to this group from people who have just acquired or built a new KX1 / K1 / KX3 and are looking for a portable end fed wire antenna length that can be matched on some combination of bands, using the internal tuner of their Elecraft Rig. The simple answer is, you need to stay away from multiples of a half-wavelength on the bands that you wish to use the antenna on. Going through some of my antenna bookmarks in my web browser I found a couple of links that I will share that should make this a lot easier to figure out a wire length that will work (i.e. load with a usable SWR) for your particular choice of bands : http://www.hamuniverse.com/randomwireantennalengths.html and http://udel.edu/~mm/ham/randomWire/ (Note that in the last figure on this second link, it is lengths with white space under the corresponding lettered band combinations that you want to use for an antenna length that will work on that combination of bands.) I hope that this is helpful. Michael VE3WMB P.S. For end fed wires (not halfwaves) I have always had good luck erecting them as inverted vees or inverted-Ls and using a few ground radials that are a minimum of 1/8 wavelength long at my lowest planned operating frequency. (ie. usually 16 ft). There was a study done that shows that unless you are deploying more than about 20 radial wires making them any longer than 1/8 wave on the lowest band doesn't really improve antenna efficiency by very much. As usual it is a tradeoff between reasonable antenna efficiency and convenience (i.e. I think that few portable operators have the patience to lay down 20+ radials). __ 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] External speakers for K3
While I tend to agree with the OP I also understand that it would be a rather mundane task for Elecraft to manufacture speakers and that their talents are bettert utilized in updating firmware, advancing the technology inside our great rigs and so on. What I did do to achieve great audio was put a pair of 5.5 Dynaudios (Danish audiophile grade woofer/mid-range drivers) in a pair of gray PVC junction boxes obtained from Home Depot. I cut the appropriate-sized mounting holes in the cover panels, stuffed some cotton balls inside, ran some tiny speaker wires through a small hole in the back and mounted the speakers with some nice stainless steel screws. Arguably overkill but since I already had the drivers on hand I thought why not put them to good use? They now elegantly perch atop my gear---and best of all---make the K3 loud and clear! 73, Jeff, NH7RO Sent from my home computer while eating a bowl of oats for breakfast. __ 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

And last but not least, what is the science of designing a transceiver with so many advanced features if the output product, the sound coming out of the speaker, is mediocre at best? Why should a company hang the reputation of its product on some other manufacturer of cheap computer speakers that will not care for the excellence and expertise invested in Elecraft's flagship system?

[Elecraft] KX3 ALERT: Internal speaker connector orientation can affect sound quality
Hi all, If you have occasional loss of audio or crackling sounds coming from your KX3's internal speaker, especially at high volume levels, you should take a look at the speaker connector to make sure it is plugged in correctly. We just discovered that if the connector is plugged in backwards, performance can be compromised. In fact this was the case with one of my lab-test KX3s. Reversing the connector eliminated an intermittent dropout I had been hearing. This may apply to either kit or factory assembled KX3s, although we're now making sure that the orientation is correct when we do assembly. Details: The 2-pin female connector for the speaker can be oriented in two ways. One way puts the plastic housing very close to the speaker (wrong), while the other results in a gap of about 0.1 (right). The correct orientation is shown in figure 17 of of the KX3 Assembly Manual. There are two small slots on the plastic housing through which the female contacts can be seen. If these slots are visible, the connector is plugged in the right way. If you plug it in backwards, the plastic housing will press up against a boss on the speaker. This can push one of the female contacts away from the male pin, resulting in an intermittent connection. The speaker may then be subject to cutting out in a way that resembles static, saturation, or distortion. Another thing you can do to improve internal speaker sound is to use revision 1.41 or later KX3 firmware (the current beta release). This release modifies the audio passband and gain distribution when the internal is speaker is used, reducing the possibility of distortion. 73, Wayne N6KR __ 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

As a retired audio professional (Fellow of the Audio Engineering Society), ham for 55 years, and contester since 1957, I have several thoughts on this question. 1) The science of loudspeaker design, while well understood, is so far removed from the science of building high quality radio transceivers that it makes no sense for a small company like Elecraft to devote their limited engineering resources to designing and building one. 2) For any serious operating, I've always used headphones. I use a loudspeaker only for casual operation, and for monitoring while I'm in the shack doing somethings else. 3) The ideal loudspeaker for ham radio is nothing more or less than one that has very smooth, uniform (flat) frequency response in the range of 200 - 4,000 Hz, maintains that uniformity over a wide range of angles where the listener is likely to have his/her ears. It should either be sufficiently efficient that it can be made loud enough by the relatively small speaker amplifiers in the K3, or it should have its own internal power amplifier. The problem with loudspeakers having internal power amplifiers is that nearly all I have seen, including some rather expensive pro models, have serious RFI problems. Loudspeakers that are relatively small tend to have smooth response over wider angles, but they also tend to be less efficient (that is, they take a bit more power to drive). Bottom line -- Elecraft made exactly the right decision to stay out of the loudspeaker business. If you want an outboard loudspeaker for ANY ham rig, simply look in the pro audio world for one that has flat response, sensitivity of at least 80 dBSPL for 1 watt at 1 meter, and fits on your operating desk. Look for audio products, not radio products. The best I know of is the RCF MR55, which is made in Italy and distributed worldwide. I've used them in some very high quality professional installations. http://www.rcf.it/products/installed-sound-systems/monitor-series/mr-55 Exception -- for many years, Motorola has marketed some small loudspeakers designed for use with their commercial VHF/UHF transceivers that works well for ham radio. 73, Jim k9YC __ 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

The speaker selected has extremely high sensitivity (95 dB SPL) and excellent audio response, thanks in part to its large (and shielded) magnet. It met our fidelity and drive-level goals for an internal speaker. The speaker is mounted on the top cover rather than facing forward based on our experiments with the K3 and earlier radios. We tried mounting the same speaker (and others) in an enclosure the same height as the K3, on the front panel. While mid and high-range audio was a little louder in this orientation, bass was significantly weaker. It turns out that response is accentuated by mounting the speaker on the top cover due to enclosure geometry (larger surface area). In most home installations the speaker audio is also reflected off the wall or equipment directly behind the radio. This, too, favors a top-mounted speaker. If you want more audio power and wider response range, you can use two passive (or powered) external speakers. The K3 was designed to drive two passive (non-powered) external 4 to 8-ohm speakers such as the KLH970 to quite high volume levels. These speakers are about 8x4x4 (HWD), so they are indeed taller than the K3, but they're black and nicely styled and look very nice on either side of the radio. I put mine on a shelf above it. The K3 was designed from the ground up to be full stereo, so I do recommend using two speakers rather than one. This gives you audio effects such as simulated stereo, as well as main/left and sub/right when using the sub receiver. We may offer our own matching speakers someday, though we have no such project in the works since (in our opinion) the K3's internal speaker does an excellent job. You can also achieve excellent results with two external unpowered speakers that may set you back $20. 73, Wayne N6KR __ 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 Speaker, Season finale
Ramon makes a point, of course, but not all of us strive for shack beautiful appearance. I see many gorgeous shacks and they probably are a joy to operate. I suspect many with such stations take pains to make it so and then do not make any changes for months or years. Then there is the other end of the spectrum (you know who you are). I figure I am somewhere in the middle with a messy station that gets a periodic clean-up for visitors. But my station is never static in configuration; I am always building something and making changes. This never lends itself to station beauty...unless that is your sense of what is beautiful. I have added a couple photo links (1st is from 2011 with FT-847 and FT-817 still in evidence; note the venerable National Radio speaker on the far left): http://www.kl7uw.com/Shack2011_1.jpg The next photo is last July showing all the new VHF gear and the new KX3 in place of the Yaesu radios: http://www.kl7uw.com/Shack2012.jpg You may find interesting the evolution of the station shown here: http://www.kl7uw.com/station%20layout.htm 73, Ed - KL7UW __ 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 Speaker, Season finale
Friends, A good point regarding these speakers is that Radio Shack sells similar speakers sometimes labeled KLH and more recently labeled Auvio for about $40. You would hardly expect Elecraft to be able to distribute as good a speaker pair for such a price. Similarly power supplies are readily available from OEM sources and available for much less that ham radio manufacturers are able to retail them at. 73 Doug EI2CN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Joe Subich, W4TV Sent: 23 April 2013 19:50 To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Speaker, Season finale On 4/23/2013 2:15 PM, Wayne Burdick wrote: If you want more audio power and wider response range, you can use two passive (or powered) external speakers.

Re: [Elecraft] Elecraft Speakers for K3
Most are satisfied with small speakers and some like the big 8-12 ones that seem to cut some of the high frequency hiss. It's not one size fits all and even a particular speaker size is not a one size fits all. I can see where a speaker enclosure that matches would be desirable for a lot of folks where you could install your preferred speaker. Look at how many $200 speakers with filters have been sold by the big3 to match their radios. I've used small ones, a kenwood one and currently using an old classroom public address speaker. It seems the large ones are hard to find around here. I've also finally got rid of my hiss/roar/frying bacon with the addition of a external equalizer and mainly pushing the 3.5 slider of the unit to -4 to -6db. (3.2 on k3 @-16). RFI was a bit of a problem for my close antenna. 73 Mike R Play me some fiddle, but no stinkin' violin!

Yes, an excellent choice, especially for CW sidetone freq. of 700Hz which is my favorite.

Hi Gary, It all depends on what one is willing to pay for, and how well it fits the application versus other solutions. You will get no argument from me on speakers versus xcvr performance, but there is room for a lot of opinions in this world. :) Wayne also made a statement (weighed in) in which he indicated a custom speaker set fo the K3 could be in the cards. I think it would depend on the pricing the group could tolerate, as well as the sales volume. Fortunately, I've already found my ideal solution, so can focus on RX/TX performance and put even more hours on my KX3 as well.

Re: [Elecraft] KX1 Firmware for KXB30
Clark, The 1.02 Firmware will handle the KXB30 as well as the KXB3080. BTW, Elecraft does not sell back levels of firmware. They are all 'backlevel compatible'.

Re: [Elecraft] KPA 100 Bias Adjustment with Fan ON or OFF?
Ray, That statement is only made so you have some understanding of the current draw that you will find. Regardless of what the current level during receive may be, you will adjust the bias pot for a 400 ma. increase in current during transmit with no RF drive. Be certain the K2 is in TEST mode. 73, Don W3FPR On 4/23/2013 5:43 PM, Ray Collins wrote: I'm setting the bias currents on my KPA 100 following the instructions at the top of page 51 of Appendix G Rev H. The paragraph states that 50 mA of the measured current increase is due to the fan running at low speed. However, in the earlier Fan Test section, the fan has been set to FAN nor mode and so should not be running with the heat sink at a room temperature of approximately 17 deg C.

[Elecraft] Low P, 160M only
So I was out on Sunday trying to make some contacts for the Rookie Roundup, as well as generally learning the ins and outs of my K2, and I found that when I try to tune on 160M I get the Low P error. I've tried using a dummy load, 20M long wire dipole, and buddypole setup for both vertical and dipole at 40M, all with the same error. I have the K2 power set at 10W, so I'm not sure if its just a poor antenna thats causing it, or should I be checking something else?

[Elecraft] Key Out
Aloha Everyone, I have the K-Line and is keying the KPA-500 vi the K3. I inserted a Pixel Pro 1B receiving loop which requires keying also. When using the Y connector at the Pixel's preamp control box as Pixel specifies, the KPA-500 keys but not the Pixel. When alone, the Pixel keys fine but not when coupled with the linear. Anyone else have this similar situation and can offer some tips or advice?

[Elecraft] [OT] Thunder storms affect Ionosphere study
David Perlman writes in the San Francisco Chronicle: New satellite to study how Earth storms impact space. A group of University of California astronomers with the help of NASA grant are launching a satellite in 2017 to study the details of how large thunder storms, particularly in the tropics can drive thermal waves upward and cause major temperature changes in the ionosphere. My own take on this story is that this study may provide a new window on how ionospheric propagation can be changed by tropospheric storms and affect radio communication. YMMV.

Re: [Elecraft] K3 Speaker, Season finale
Us OTs who occasionally peruse the old QSTs know that in the 1960's Collins was really trying to produce equipment that the XYL would not object to having on a desktop in the living room. Hamshacks were moving from the basement, garage or outdoor shed into the living room. As home sizes have diminished steadily over the decades, and the size of the equipment has diminished, having a rig that was acceptable in the living room has become how many Hams have stayed on the air. Personally, my rigs are almost never fully assembled. When I'm on the air, it's usually with something that looks like someone exploded a dozen pieces of equipment on the bench top. Fortunately my XYL does not mind and now that solid state is common, I'm no longer reaching through a maze of wires containing hundreds or thousands of volts to throw a switch. (Yes, I was raised with the story of how Ross Hull was electrocuted in 1938, exactly 7 months and 12 days after I was born probably instilling a level of care that has probably been responsible for me surviving, although I have been knocked on my...er...'backside'... a number of times in years long past.)

I can understand the desire to know exactly what one will hear on which frequencies for many, but I personally enjoy turning on the rig to be surprised by and enjoy whoever is on the air. No, I do not use clusters or any other internet support. I barely even look at the MUF charts. (Are they still in QST? Haven't seen them in a while.)

Re: [Elecraft] [OT] Thunder storms affect Ionosphere study
My inner scientist wants to know, even if I don't make any practical use of the information. The idea that tropospheric weather affects the ionosphere was new to me. Finding out exactly what the effects are arouses the inner scientist. I also have not used clusters etc. My recent big thrill was tuning about 14073 for no specific reason and seeing a weak PSK63 signal. I was able to work Zac in Israel from California at 12W. I gave him a 439, although the 4 may have been a bit generous. When I went to find an address for a QSL, there was no QRZ.com entry, so I Googled the call. I found a lot of spots, and a QRZ.com entry for the QSL manager.

Re: [Elecraft] K3 Speaker, Season finale
I would disagree on the size. I have a book Weyrhauser put out in the early 1950s for people to choose plans from to build a house. The sizes ranged from 600 to 1100 square feet. Try to find houses that small being built today. Two to three thousand are common and four to five are not unusual. I will admit that houses built in the 1900 to 1920 era may have been larger. But they were built for large families and quite likely a hired girl. In 1934 Sears offered material bundles for homes. I just saw an advertisement for two. Three bedrooms - 960 and 1050 square feet.

Re: [Elecraft] Low P, 160M only
Jeremy, Is the problem you cited a recent change in the behavior of your K2? Also, do you have the KAT2 installed? Since the problem occurs on 160 meters only, and even when using a dummy load, I wonder if the 80 meter/160 meter alignment procedure (see K160RX manual) needs to be repeated? The Lo P message could be displayed if you accidentally placed the K2 into Test mode, i.e. disabled the transmitter, then attempted to key the rig, but this would also be apparent on other bands too. 73, Mike, K8CN -- View this message in context: http://elecraft.365791.n2.nabble.com/Low-P-160M-only-tp7572970p7572978.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

I know for a fact that average homes of the late 40's through early 60's were considerably smaller than common today - typically 1500 square feet was considered large. My father was a draftsman on the design team for one of the largest kit built home manufacturers in the mid-west right after WWII when they were cranking those homes out by the hundreds of thousands to supply the needs of all the returning GIs who were setting up households. Not only were room sizes typically smaller than those today - the average house of the 50's and 60's lacked a formal dinning room or separate family room. The two additional rooms plus a second full bath in homes of the 80's and later represented a significant increase in the average home size - even before considering the larger room sizes and additional storage space in modern homes. 73, ...
