Fred, K6DGW wrote: ___ I've noticed recently that the VFO shaft encoder doesn't seem to count reliably. I usually run in the 100 Hz resolution, and turning it slowly in the increasing frequency direction will sometimes result in a 100 or 200 Hz decrease. The key seems to be slowly, going faster seems to be ok. I am sure this is recent (last few weeks) and wasn't a problem when I first finished the kit. Is this a common problem? Is it fixable? I finished bought the kit at Pacificon in Oct 04 and finished it a couple of weeks later. I will admit that my KX1 is getting quite a bit of use ... I worry the K2 is feeling like an ignored step-child these days. Yep, mine (KX1 #702) does it also, and only on the highest resolution setting. I don't know exactly how the encoder output is patterned, but it seems like it may have something to do with the increased shaft play or wobble associated with the pushbutton function also built in to the encoder, perhaps allowing the encoder to start off in the wrong direction briefly when you start to rotate it. I have never reported it because it is just a very minor irritation, and really doesn't interfere with my being able to set any freq I want. 72 / 73, Bill K4DXU ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Re: It's Alive !!
Hi Jeff, Congrats on finishing your K2 # 3375! Judging by the S/N you've had the kit awhile. Just a tip regarding programming your filters for SSB, be sure to follow the instructions in the K2SB manual, you will get much better results. Have you added the latest mods, if not I recommend that you do so. I recommend that if you intend to use the K2 extensively on SSB that you consider adding the KPA100 amplifier, it makes a real difference when you can be heard, 10 watts just isn't enough power for consistant SSB contacts. Keep us informed. Will look for you on the Trans Provincial Net on 7.055 mhz. 73, Bob VE3XM K2 S/N 02676 K2/100 S/N 04031 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] KDSP2 Troubleshooting
Hello all, Have just completed the K2DSP and all appears to to work FB, except for a loud pop on power up. The troubleshooting section of the manual indicates that this may be down to a problem with the mute circuitry. As an initial check, went through the voltage chart and compared my results, with the following differences (manual value in brackets) U1-5 = 5v (0v) U1-14 = 0v (5v) U1-15 through U1-19 = 5v (0v) D3-C = 5v (0v) The interesting difference is U1-14 which I believe is the MUTE output from U1 and which according to the manual should be at 5v but I have 0v. If however pin 14 was at 5v then looking at the diagram Q7 would be turned on, yet the table has voltages showing Q7 is off. Have I got this wrong, or is the manual incorrect? Why do other pins have different voltages to the manual, even though the DSP functions all appear to be working OK? The other active part of the mute circuitry is the pair of FETs Q5 Q6, and I am a bit concerned that one or both of these may be damaged. During the install, it is not until page 10 when it states that Q5 Q6 are sensitive to static. In all the previous Elecraft builds I've done, if any transistors were static sensitive, they were put into the conductive foam along with the ICs, but in my KDSP2 package they were just loose in the bag with the bulk of the rest of the components. As a consequence,I never thought to take any special anti-static precautions hadling these during the inventory check. Is there a quick way of checking their fuctionality before ordering replacements? Any help would be much appreciated. 73, Don M1DIC K2/100 #3082 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] Soldering stations, sources, and costs (was: no subject)
I need some recommendations on a soldering station and also approx cost if you know it. I'm having good luck with the Hakko 936 I bought from www.wassco.com for $88.50. Read the recommendations scattered throughout the Elecraft site (Builder Resources has several articles) and you'll find all you need for tools at Wassco. I tried using Digi-Key (www.digikey.com) but what a horrible Web site!! They've scanned their print catalog into PDFs and you have to copy the part number from the catalog into an order form. This is like e-commerce circa 1995. The only thing lamer would be if they just gave you the PDFs for the catalog and had you print out an order form and mail it in. Mouser (www.mouser.com) was slightly better but still has a print catalog orientation. You can't get to pictures of anything until you follow several layers of links, and then it's PDFs of their catalog pages with tiny line drawings. At least you don't have to copy the part numbers to the order form. Wassco is organized by product category and manufacturer and has nice color pictures of everything they sell. They have a print catalog you can view online, but it's not necessary to look at it in order to place an order. I didn't bother to figure out if their prices were more expensive than the other sources because it was so hard to figure anything out on those other sites. As a person who has put together several Web sites including rolling my own e-commerce site, the process of buying tools for my K1 project was an interesting study in Web design and marketing. It's interesting that an industry that might be considered high tech (i.e. electronic parts and supplies) seems to lag non-tech industries (to pick one entirely at random: check out the simplicity of ordering knitting supplies at www.purlsoho.com).

Re: [Elecraft] (no subject)
Hi, all, I believe Isolated Tip refers to the tip being isolated from the power to the heating element, not isolated from ground. If memory serves, this was to distinguish this type from the gun type where the tip was a part of the heating element circuit and had voltage applied to it by a transformer. I think all, or virtually all pencil type irons these days are isolated tip. 73, Mike Bowles, WH6AH At 04:23 PM 1/27/2005 -0500, W3FPR - Don Wilhelm wrote: Bob, I am not certain what they mean by isolated tip unless they are inferring some kind of 'people protection' from electrical shocks - the tip on mine certainly is connected to the ground pin on th eelecrtical cord. ___ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Which Mods Are Applicable??
Jim, If you are ordering a new K2 kit, you don't need any of the mods - all the 'standard' ones are already incoprporated into the design. If you have (or are buying) and older K2, look first and most at those mods that have been incorporated into the current K2 design. That number is much smaller than all the mods published on Sverre's website. If you have a pre-SN3000 K2 that you would like to bring up to date, the best starting point is with the A to B mod that is packaged by Elecraft (along with the optional mods mentioned in the A to B instructions), incorporates many of the earlier changes. Beyond the A to B mods, the Temperature Compensated PLL change, the Keying Waveshape mod, the addition of D40 and D41 for high level on frequency signal handling are the additional changes you need to bring your K2 up to date - of course, some of the changes require updated firmware, but the Elecraft site is helpful in determining what you need. Many of the other mods listed in Sverre's webpage are additional changes that some K2 owners have found helpful because they have had special needs or conditions (the European 40 meter bandpass filter changes for instance). You should review these carefully while considering whether or not you have a similar need or condition with your K2 before applying that mod, and some may change the operation of the K2 to suit a particular operator's taste - for instance, my mod to separate the CW PTT from the Dot paddle line is not desirable unless you have a need to add that function, VHF folks who run a sequencer chain may need it, or contest ops who want to use a footswitch on CW, or SO2R stations that need to use PTT steering would need that function, but the majority of others would only find it bothersome. I hope that helps a bit with your selection and decisions. 73, Don W3FPR - Original Message - In trying to cover all be bases before order a K2 with many of the bells and whistles I've found reference to modifications.

Re: [Elecraft] Which Mods Are Applicable??
Jim: I guess my approach would be to buy and build the basic K2 first. My S/N 3401 just missed having the temperature stability mod included (I think they started with S/N 3425 or so). Anyway, the only mod I ended up making on it was that one. I am totally happy with the radio in that configuration. Looking back on things, I probably didn't even need the temp stability mod, since I'm not planning to add the amplifier. I added several options, but have made no other mods. I've heard the key click mod is another important one, and I might end up building that one, but for now I'm happy with what I have. I believe that if there were truly any important mods that needed to be made before the radio performed well, they would have been included with the basic kit. It works well right out of the box - after many hours of soldering (hi). My 2 cents worth. John AA0VE Jim Harris wrote: How does one determine which should/need be purchased?

OK folks, I will try an entire re-write to get the info out. Prior attemps were rejected because of some offenive word(s) in the body. I discovered that I had modified my Soloman station 5 years ago. I added one 1 meg resistor from a wire that does connect to the tip shell to the grounding post on the back and another 1 meg resistor from the grounding post to the line cord ground wire, so my soldering station does have an ESD discharging path to ground. Easy to do, and I will supply details if anyone asks. 73, Don W3FPR - Original Message - The Soloman 4449 is listed as having an isolated tip.

Re: [Elecraft] SSB adapter, T1
Kevin: That is perfectly ok. If you look at the schematic, one terminal of each side of the transformer is connected to ground. This ties the two windings togethter DC wise but not RF wise. 73 Jim Younce K4ZM K2 SN: 18 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] SSB adapter, T1
Thanks to all who responded on what I thought was a problem. You were all right. If I had looked at the schematic I'd have seen that the windings do have continuity for DC. I got into that toroid winding state of mind and didn't think to check the schematic. Thanks and 73 -- R.
