[Elecraft] Elecraft support
Dear Fellow Elecrafters, I am writing to report on my experience with Elecraft support. My K3 (820) recently developed a perplexing and irritating behavior: as I would tune in a cw signal, I would come across a frequency very near the CWT center frequency where the signal’s tone would disappear, and I would hear only key clicks. This was a very sharp null, and I would hear a good tone either side of it. I contacted Elecraft support, and Gary walked me through checking for obvious problems, like whether I had the notch filter engaged (I did not). Then he shared the problem with Lyle, who suggested that such a null could occur if I had set SPKRS=1, and AFX was turned on. I use only one speaker, so I did have SPKRS=1. And with mono headphones, I have no need for AFX, but I found that it was turned on. I would not intentionally have turned it on, but I often do direct frequency entries, and I must have erroneously hit the AFX/Enter key with multiple presses or poor timing. I turned off AFX and the problem disappeared. But this story is less about my problem and its solution than it is about the energetic and competent support I received from Elecraft. Gary was prompt in responding to my request for help, and he also was quick to call in Lyle to be sure that appropriate expertise was brought to the problem. And I noticed that all correspondence was copied to Wayne, so that he was in the loop as well. I could not have asked for better support. 73, John, no8v __ 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] KX1 headphones
A couple of years ago I decided that I wanted new headphones, so I checked ratings on eHam and bought a pair that featured a frequency response tailored for communications use. When I tried the new headphones, I found them comfortable to wear, but it soon became apparent that they exacerbated noisy band conditions; it was like listening in a rain barrel. I then set the new headphones aside and went back to a much older pair with a nominally flat frequency response that I find much easier to listen to. 73, John, no8v __ 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] Need a kit recomendation (off topic a little)
Hi Alan, Please consider MFJ's 8100K regenerative receiver kit. It provides reasonable shortwave performance, and its regeneration control can be adjusted for ssb and cw reception. The radio's open layout makes it a good kit for beginners, and the $80 price includes a nice case. The kit assembly even requires the winding of one toroid. I used to teach an Introduction to Radio course for liberal arts students, most of whom had never before seen a soldering iron. They had a ball building these radios, and the few radios that did not work when first turned on were easy to troubleshoot. 73, John, no8v Original message Date: Fri, 24 Jul 2009 08:45:05 -0700 From: elecraft-boun...@mailman.qth.net (on behalf of Alan Price w1...@arrl.net) Subject: [Elecraft] Need a kit recomendation (off topic a little) To: Elecraft elecraft@mailman.qth.net I purchased an AM radio kit for my five year old grandson.

Re: [Elecraft] Re: K3 Key-down on power-up [Solution?]

I could prevent the rig from being keyed (by any method) during the first couple of seconds that it's powered up. Instead, it could detect this case, and display a repeating message (something like: KEYLINE IS ACTIVE) until you either remove the source of the keying or turn power off. Thoughts on this? 73, Wayne N6KR Dave Hachadorian, K6LL wrote: I've got my K3 set up for cw on Field Day with a laptop usb port driving a usb to serial converter. Rig control and cw keying are done over the serial cable, using the K3's built-in ability to send cw from pin 4(?) of the rs-232 cable. Everything works fine, but I got quite a scare when I turned on the K3 and it came up keyed-down 120 watts into no antenna. It seems that if the laptop is not running the logging program, rs-232 pin 4 can very well be in a key-down state. --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] [K3] AFX operation
Hi Lyle, Thank you for your explanation of how AFX works; I now better understand how AFX currently behaves. While listening to cw, I find that increasing DELAY shifts the apparent source of a cw signal further to the left, which makes me believe that AFX delays the right stereo channel. AFX does provide a nice spatial sense of the sound (albeit with sound sources shifted to the left of center). I know that your plate is full right now, but I was pleased to hear that you are thinking of a a future AFX with that spatially locates a sound source based on its pitch.

This is not what I expected. What am I doing wrong? The K3 does not provide a space based on pitch which is apparently what you were expecting. That effect is on the list of things to consider for the future. BIN provides a fixed phase shift between the two channels. DLY provides a fixed (but user selectable) time delay between the two channels. I use DLY 3. Wayne prefers DLY 5. This is *all* what we call psychoacoustics, mainly because we like to use 5 syllable words to impress :-) Different listeners react in different ways to these settings. There is no correct one; use what you prefer, including OFF. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] [K3] AFX operation
I have recently begun experimenting with my K3's AFX feature. My understanding is that AFX is supposed to spread cw signals across a virtual listening space in front of the operator (distributed according to pitch?). My experience, listening with stereo headphones and with AFX on, is that all of the sound seems to come from one side and slightly to the rear. With AFX off I hear a balanced sound from the headphones that seems to be in the center of my head. This is not what I expected. What am I doing wrong? 73, john, no8v ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] MFJ-4125 Fan Noise
Question for the List: I recently bought an MFJ-4125 switching power supply to use with my K3/100 transceiver. While otherwise satisfactory, the MFJ-4125 has an objectionably- noisy fan. On my MFJ-4125, over half of the fan exhaust openings on the back of the supply are blocked by the fan's motor housing, which makes me believe that the power supply originally was designed for a different fan (perhaps a quieter one), and this fan is an expedient substitute by MFJ. I would like to know if other users also are bothered by the MFJ-4125's fan noise, and what they have done about it. Have you substituted a quieter fan? Have you installed a series resistor to slow down the fan, and with what result? Have you installed a thermostatic switch to run the fan only when needed? Or have you given up and simply bought a quieter power supply? Any advice would be appreciated. 73, John, no8v ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K3 band switch clutter
Don, Thank you for your excellent advice (as always). I am aware of the other methods of jumping to the ham bands, i.e. direct frequency entry and setting up memory pushbuttons. I merely wanted to know what I could do about the band switch itself, and you gave me a satisfactory answer to my question.

I recall that there has been discussion about just where inside the ham band the band button will place the K3 - i.e. if you tune out of the band at the bottom end, return to the lowest frequency in the band? if you tune out the top of the ham band, then do you return to the top of the band? Or should it return someplace else - everyone will of course have their favorite answer on this one. Until it is settled and is coded into firmware, Direct Frequency Entry will get you back into the ham band. If you have set up a memory for the ham band in question, a tap of the MV button will do it - both these solutions are easier than twisting the VFO knob until it is back in the ham band. 73, Don W3FPR John H Gibson wrote: Question for the list: On my K3 (SN 820) I have noticed that if I tune to frequencies between the ham bands (e.g. WWV frequencies), these frequencies then show up when I step the band switch up and down.

RE: [Elecraft] K3 VFO A tuning knob set screw
Hello Thomas, I can use the allen wrench to extract the set screw from the VFO A knob. When I hold the set screw against my 8-32 tap, the threads mesh, and the diameters appear to be the same. Even though the set screw thread meshes with that of my 8-32 tap, the set screw is not long enough to make me feel certain that they are the same, rather than merely being close. I am not familiar enough with nominal metric threads to know whether there is one that is close to 32 threads/inch. There is an identical set screw in the VFO B knob. Either set screw will thread easily into the VFO B knob, but either set screw will go just so far and then bind in the VFO A knob. 73, John, no8v Original message Date: Sat, 3 May 2008 21:26:04 +0200 From: Thomas Norff [EMAIL PROTECTED] Subject: RE: [Elecraft] K3 VFO A tuning knob set screw To: [EMAIL PROTECTED] Hi John, i am living in 'metric land' and i'm shure this is not metric.

Re: [Elecraft] OT - Heath CW Twins
Hello David, Chuck Penson's excellent book, HEATHKIT: A GUIDE TO THE AMATEUR RADIO PRODUCTS, 2nd Ed., lists both the HR-1680 and the HX-1681. According to Chuck, the HR-1680 was released in the Fall of 1967, but the HX-1681, which initially was advertised as coming soon, was plagued with problems and not released until the summer of 1979. Continuing Chuck's comments, early HX-1681s had key-click problems, and Heath provided a free modification to owners to remedy this. This modification was included in later-production HX-1681s. A modification to solve the key- click appeared in the March, 1981, QST. Eventually the HX-1681 was pulled from production a year earlier than the HR-1680. Chuck further says that, the both the HR-1680 and the HX-1681 use plug-in circuit cards, and the card-edge connectors are subject to oxidation over time. These connector contacts may need periodic cleaning. Overall, Chuck Penson has kinder things to say about the HR-1680 than he does about the HX-1681. I hope this is helpful 73, John, no8v ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] OT - Heath CW Twins
Jim, N2EY, is correct; the 1967 is a typo on my part. Chuck Penson states that the HR-1680 was released in the Fall of 1976.

RE: [Elecraft] Miniature screwdriver sizes
Mike: Last week I spotted a neat 4-in-1 miniature screwdriver for sale at the checkout counter of the local hardware store. It is about the size of a Sharpie marking pen and has a pocket clip. Included are two very small flat-bladed screwdrivers and two very small Phlllips. The case is a tough plastic, but the reversible bits are metal and appear to be precision ground. The price was only $3, and I could not resist. I am very pleased with my purchase. The label on it says Enderes Tools. I could not find this particular tool on their web site, but an internet search did turn it up on eBay. I expect it is being marketed as a promotional item. 73, John, no8v -Original Message- I'm in need of a very small phillips screwdriver, but haven't been able to find actual dimensions of them and I don't know what size a #0 would be, etc. I thought someone on this board might have some advice. The slots in these screws are .064 or 1.63mm. Any help would be greatly appreciated! -- 73, Mike, KC0KBC Yaesu FT-857D, FT-8800R, VX-7RB Elecraft KX1 #1819, XG2 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] OT: Keying contacts
On the topic of keys, paddles, and bugs, I wonder if members of the list would tell me how they keep key contacts clean and reliable. Do you regularly burnish key contacts? Do you use a chemical cleaner (e.g. de-oxit)? Do you maintain a minimum keying current? Or do you simply never have a problem? Please share your wisdom and experience. 73, John, no8v ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Crystal Clear book
I just finished reading a book, CRYSTAL CLEAR, by Richard J. Thompson Jr. The book presents the fascinating history of the World-War-II effort to provide crystal frequency control for military radios. This was critically important, because radios without crystal control drifted badly, which made net operation difficult and also made it impossible to assign closely-spaced radio channels. The book was announced in the New Book section of the June 2006 QST. The book's author had written a nice summary article on the same topic that appeared in the January 2004 QST. I make mention of the book here because I know that many members of the Elecraft list have long memories and share my fascination with radio's technical history. (Like Ron, AC7AC, I too remember Edward R. Murrow's reports from London during the Blitz.) I do not know Professor Thompson, and I have no vested interest in the sale of his book. 73, John, no8v ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] All-band folded dipoles
Here is what L.B. Cebik says on the topic of all-band folded dipoles. http://www.cebik.com/wire/wbfd.html 73, John Gibson, no8v A lot of them have been replaced by the now-ubiquitous BW All Band Folded Dipole - the same antenna that I use in an open-V configuration. It works equally flat over the HF (1.8-30 MHz) spectrum. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
