[Elecraft] KX1 guide for non-builders
I just finished building a KX1 for a friend and it occurred to me that you pick up a lot of information about the radio during the build process that could come in handy as an owner/operator of the radio. Unfortunately this information is lost if someone else builds your KX1 or if you buy one on eBay. I wrote up a little 3-page guide for my friend and thought some of you might find it useful. I've posted it as a PDF on my site: http://www.craigr.com/Elecraft%20KX1%20Maintenance%20Guide.pdf If you have trouble with the link just let me know and I'll send it to you. The goal of the guide is not to repeat information from the manuals but to help you find it. In some cases (such as a complete disassembly procedure) there's nothing in the manual. In other cases (such as receiver alignment) the procedure is split between two or more manuals. Hope it's useful.

I believe we have sold 2D fasteners to experimenters in the past; check with sa...@elecraft.com. We also sell blank project enclosures styled to match the K2 (EC2) and K1 (EC1). There are two different height tilt stands for the EC2: ETS15 (1.5") and ETS2 (2.5"). You'll find these on our order page. I bought a few, and then built a box that's the same width and depth as the K2, but high enough for the Clifton Labs Z90 panadapter. It's got one piece with two bends in parallel (the front panel), two pieces with only one bend (bottom and top) and two pieces that are just flat. I had to set the shear fence ONCE to get the widths cut. There's no nothcing necessary either in the sheet metal nor in the brake.

Re: [Elecraft] W1 Power Meter and W8FGU Case
Bill, I have not had any problems myself, but some boards "suck away" the heat from the soldering iron tip more so than others - and that is true whether the boards are RoHS or not. I routinely use about 750 deg F for soldering and bump it up to 800 deg if the board traces are large or there is a large ground plane. Leaded solder usually works fine with the RoHS boards too. Just be certain to heat the pads adequately - watch for the point when the solder flows out onto the pad. If the solder pads are not adequately heated there will be a poor solder connection just waiting until some crucial moment to fail. Murphy strikes at the worst possible moments. Many, boards that I "repair" are solved by reflowing the solder with a hot soldering iron. There seems to be a tendency among some builders to not heat the solder pads. Whether that stems from old experiences of lifting solder pads on poor boards or fear of damaging components, I just don't know, but when using a temperature controlled soldering iron and applying heat until the solder flows, those fears should be put to rest. Elecraft uses thru-plated holes on the boards and components will stand soldering temperatures for short times (usually 6 to 10 seconds), so there should not be a fear of damaging components with soldering heat applied for 2 to 3 seconds. On a normal size solder pad, if the solder does not flow in 3 seconds, the iron is not hot enough and if it flows in less than 2 seconds the iron is too hot. My other 'rule' is to use a solder thin enough so you can control the amount of solder applied easily (.015 to .020 inch diameter) and a mildly activated flux so the flux does not create a mess (Kester 285 is my opinion of good solder and flux). 73, Don W3FPR Bill Miner wrote: > Hello Elecrafters, > > I just completed assembly of a W1 Power Meter kit.

Re: [Elecraft] Is my AFSK A problem a Ghost?
In my previous message I forgot to mention one other difference between AFSK A and DATA A sub-modes. In AFSK A, the K3's dial displays the actual mark frequency, whereas in DATA A the dial displays the suppressed carrier frequency. Thus, to tune in the W1AW RTTY bulletins on 14095 kHz, in AFSK A you would simply set the K3's tuning dial to 14095. In DATA A, if you wanted to center the signal on exactly 1500 Hz, you would set the radio's dial to 14093.415 kHz (1585 Hz below the desired mark frequency). I don't know for sure what frequency DM-780/HRD would log in each of these two cases, nor how to correct any offset if there is one. 73, Rich VE3KI __ 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

My experience also. The VA gave me some new digital [DSP] hearing aids a few years ago. They will notch a fire truck siren down to a tolerable level, and do a fine job of extracting voice and music from noise [except for sustained notes]. I hadn't heard birds in nearly 40 years until I got these. However, they apparently think CW is a fire truck. I am finding that my K3 NR performance is very sensitive to other RX settings as well as the DSP BW. The recently posted suggestions for AGC settings have helped a lot. I'm pretty much CW-only because of my hearing, I have the stock roofing filters, and I usually run the DSP around 250 Hz. Engaging NR at one of the lesser aggressive settings raises the volume of the signal, I turn down the AF Gain, and the noise subsides nicely with the signal now standing out in my headphones better. There seems to be a threshold level below which a very weak signal can't be found by the NR algorithm but I haven't had time to experiment with the NR settings yet. Possibly a more agressive setting will lower that threshold. Really agressive settings seem to create more garbage than they reduce noise. Haven't gotten to SSB yet. My K3 is definitely NOT your father's radio :-) 73, Fred K6DGW - Northern California Contest Club - Auburn CA [Placer County, CM98LW] __ 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] Is my AFSK A problem a Ghost?
Doug, DM-780 appears to start with its tuning guides at 1415/1585, which does not match any of the K3's RTTY pitch settings exactly, but is quite close to the K3's 1445 Hz setting. With the K3 in AFSK A sub-mode, hold the K3's PITCH button (just above the VFO B knob) to see the pitch displayed in the main display. Using the VFO A knob, you can adjust the K3's Pitch setting to 2125, 1445, 1275 or 915 Hz. I would suggest that for DM-780, you start by setting the K3's pitch in AFSK A to 1445. This will work fine at wider filter settings. If you are using a very narrow filter setting on the K3, you may have to move DM-780's tuning guides slightly to center them on 1530 Hz instead of 1500 Hz. I would also suggest disabling AFC in DM-780, as that can cause the tuning guides to move away from the center of the filter bandpass. If you use the K3's tuning knob to do all of your tuning, you will always be centered in the bandpass. If the radio's tuning seems too touchy for this, try pressing the K3's FINE button to see if that helps. I don't usually use DM-780 (DM-780 and HRD each seem to work on their own, but the combination locks up on my computer), so I am not very familiar with it. However, it looks to me as if DM-780 expects the radio to be on upper sideband, whereas the K3's AFSK A uses lower sideband. You may have to press the Reverse button in DM-780 to get it to decode RTTY correctly in AFSK A sub-mode. DATA A works fine for you because it is centered on 1500 Hz (the same as DM-780), and it uses upper sideband (ditto). On the other hand, in DATA A mode you do not have access to the K3's RTTY-specific features (the Dual PB filter, spot tones and CWT tuning aids, and text decode). Note also that with DM-780 you must use AFSK A and not FSK D sub-mode for RTTY. AFAIK, DM-780 does not support FSK keying, only AFSK. 73, Rich VE3KI > no RF and do not > hear anything on Monitor playback. > > Everything works OK in Data A both RTTY and PSK. > > 73s, > Doug - W5ION __ 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] Absolutely fantastic customer service!!
With the help of Gary, AB7MY, of Elecraft, and Don, W3FPR, of this list, I've just resolved the most crazy problem of my nearly 50 year ham career. About a month ago, I decided to upgrade my K2/10 (#337) to a K2/100. After inquiring here about how the KPA100+KAT100 in an EC2 enclosure might work (the answer was "very well"), a list participant offered his already built KPA100+KAT100+EC2 to me and I accepted. Then I needed to complete the a-to-b upgrade of my K2 that I had only done part of before. After that I discovered that when using the KPA100, I had all sorts of weird RF-related symptoms that I'd never experienced before. I then did all the KPA100 upgrades that Elecraft recommends, with no change in the problems. Then I began e-mailing with Gary and Don and they gave me lots of advice, most of which I followed, with no change to the problem. I'll spare you the details, but will mention that one thing I played with a good bit was the length of my 450 ohm feedine to my inverted vee dipole. None of that helped. A couple of days ago, I e-mailed Gary that I was ready to give up. He encouraged me to hang in there, and then yesterday suggested that I just try adding some coax between the KAT100 and the BL2 balun that I use. I grabbed a random piece of RG-58 with connectors on it - about 6' worth - and plugged it in. Voila! Problem solved! After all the stuff I tried, I'm floored that the problem was resolved by such a simple change!! I guess its a kind of mojo!! Anyway, thanks to Gary and Don for not letting me give up, and for having the patience and persistence to keep suggesting stuff to try! This is one of the reasons I stick with Elecraft!!!

Re: [Elecraft] Is my AFSK A problem a Ghost?
Doug I use DM-780 and discovered the same thing you are experiencing once in a while. I finally figured out what I was doing wrong. I narrowed down my K3 filter to 250 hz and saw on the display that I was centered on 1500 hz in Data A mode but when I switched to AFSK for RTTY it was centered on 1000 hz. If If I click on a waterfall very far from the 1000 hz I will not hear or tx the tones. Try finding your center BW tone/freq on the waterfall and tune the station to that and see if your monitor and tx output works. Ron NA9F no RF and do not hear anything on Monitor playback. Everything works OK in Data A both RTTY and PSK. 73s, Doug - W5ION _ Doug Freeman d...@dougfree.com www.dougfree.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 -- View this message in context: http://n2.nabble.com/Is-my-AFSK-A-problem-a-Ghost--tp2748776p2755343.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] K3 Kit Building
The "2D" (where did that name come from?) fasteners are handy, but they don't maintain much in the way of shielding integrity. If you want decent shielding then you need continuous contact between panels and a lot of screws. You could always make your own, for example, here's a photo of an amplifier I built about 30 years ago that shows what I'm talking about (although for *really* tight shielding twice as many screws would be called for): http://k6mhe.com/n7ws/N7WS_8877_1.jpg Wes Stewart, N7WS ps.

[Elecraft] K3: rear panel fitment/alignment
Hello all, My K3 has been built for some time, and working quite well. However, I've been a bit curious about the rear panel alignment especially as it relates to the ground post and power pole connection. Those two never seemed to line up right with the cutouts in the rear panel, while all other things did. The powerpole connector in the back was quite off-centered. As it is, the rear panel cutout for the power connecter sits in the recess of the connector, and if you look at the back, the powerpole connector is shifted over to the left leaving a small gap. It doesn't seem stressed, but I was wondering if that's typical? I've done just about everything to make sure everything was lined up, including readjusting the 2D fasteners, but that didn't help. 73, James K3JPS __ 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 believe we have sold 2D fasteners to experimenters in the past; check with sa...@elecraft.com. We also sell blank project enclosures styled to match the K2 (EC2) and K1 (EC1). There are two different height tilt stands for the EC2: ETS15 (1.5") and ETS2 (2.5").

Re: [Elecraft] K3 switching to split freq question
Rob, I'm not saying that some logging programs and K3 control programs are not in need of some changes but your problem could have at least been avoided/circumvented by something that I reported to K3 support some time back. CONFIG parameter CW WGHT was enhanced to provide a SSB+CW function which allows CW keying in SSB mode. Works great when not in SPLIT but does not work while in SPLIT. The response from support was that this was on the 'fix' list but again that was quite a while ago. If this would have resolved your problem perhaps another note to support would help.

Re: [Elecraft] K3 Noise Reduction..revisited
Regarding noise reduction and the BHI products; I've noticed that the BHI ANEM works substantially better than the K3's NR. For whatever reason, whenever I switch NR on, the band noise seems to get attenuated slightly, but then reshaped to resemble noise in a tunnel. It's very tiring to listen too. Any suggestions? 73 de James K3JPS Trevor Smithers wrote: > As far as I'm aware there are two companies that produce this technology for the amateur > market, BHI in the UK and Michels-Engineering in Germany.

[Elecraft] Filter feature request
The filter reset function (knob press) that selects NORM, NORM 1, and NORM 2 is helpful in getting the filter width back to a preset value which can be different for each mode. It would be helpful, however, if the lower display briefly showed the filter width after the knob is pressed. Right now it displays -NOR-, NORM 1, or NORM 2 while the knob is being pressed and then immediately jumps back to the VFO B frequency. I have to rotate the filter width knob (or double press it) if I want to know the current width. 73, Mike K2MK __ 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 Noise Reduction..revisited
Hmm, are Lyle's "other irons in the fire" being heated for Eric's "other fish to fry"? :-) More seriously, I also would love to see changes to the noise reduction, particularly to help with weak signal work. I'm not sure why anyone cares about noise reduction for strong signals -- I just turn down the AF gain and the noise goes away :-) Steve N9SZ Don W3FPR wrote: Perhaps Lyle is looking at other alternatives for NR in the K3, but I do know that he is quite busy with other 'irons in the fire' right now, so patience is a virtue for now and we could possibly discover improvements down the road. __ 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
