[Elecraft] K2s looking for a new home
Hi, I have 2 K2s immaculately built and documented by Clemed Nilsson SM7DRH (sadly SK). I received them in a trade. I repaired them (swapped 2 latching relays and replaced 2 potentiometers) and tested them and they work very well. Serial no: 288 (pretty much all extra options that I'm aware of including a Heil mic and internal ATU and CAT) and a firmware update. Serial no: 5183 no extras Because of other projects I don't get to use them as much as they deserve. I don't know if there's still any interest in these rigs? But it'd be nice if someone could put them to better use than I can. If you are interested, give me a fair offer/trade and I'm willing to part with them. QTH is Göteborg southwest Sweden.

Re: [Elecraft] K2s
Besides the parts access issues, another consideration is keeping it buildable. If the K2 were to be updated any further, it might go out of reach as a buildable-by-mortal-hams kit with discrete components. In fact, there are compromises in the rig already to keep it easy to build, I'm thinking the synthesizer circuitry for example. You'd have to basically do what Elecraft has already done, which is go to more of a final-assembly/no-solder kit so that the touchier parts of construction could be done at the factory, etc. Else, we'd have to start doing SMT soldering, or just an endlessly complicated kit that would take absolutely forever to build and require esoteric or expensive tools, etc. So as-is, the K2 is already about the top of the line in terms of what you get performance/features-wise in a kit that even ham-fisted (so to speak) builders like myself can actually build and have a working rig at the end of it. I've built two copies of the K2 so far, but I think I'm done for now lol. These should last me for the duration. But if you're thinking of building one, probably best to do it sooner rather than later while Elecraft can still get parts... 73, LS W5QD -- View this message in context: http://elecraft.365791.n2.nabble.com/K2s-tp7619218p7619261.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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] K2s
Robin, I understand about your pleasures of the K2, but I doubt you will see any more upgrades to the K2. Just enjoy it as it is right now (unless yours could use the upgrade kits that are available). Parts for the K2 are becoming harder and harder to source, but Elecraft has done a magnificent job of trying to keep up with alternatives as the availability of the original parts has vanished. A few that I have been involved with are the substitution of the speech processor on the KSB2 option, the unavailability of SA612 ICs in DIP format, and the lack of trimmer capacitors that were used in the past (which created the demise of the K1 4 band board). I am not sure how much longer the K2 can "hang in there" as a new kit with the world switching to SMD components and leaving the thru-hole components behind as obsolete. Time will tell, but what I am saying is that Elecraft has made successful substitutions so far, but there will be a day when that is no longer possible. I also hate to think of the time when proper replacement parts for the K2 are no longer available, but I do see "the writing on the wall". So to ask for improvement for an 18 year old design may be asking for more than can be reasonably accomplished at a desirable price point. 73, Don W3FPR On 6/24/2016 12:09 AM, Robin Bayer wrote: For casual CW, the K2 sounds and performs.

Re: [Elecraft] K2s
It's not just the fun of building it, it's also the fun of using a radio you built yourself. It's nice to be able to undrrstand and appreciate the design, which is harder with the KX3 since the most interesting parts are locked away out of sight in proprietary code. One feature I really like about the K2 is you can plug in paddles, straight keys, bugs etc. all connected in parallel and the K2 will automatically detect which is which. 73, Matt VK2RQ On Sat, Jun 25, 2016 at 12:35 AM +1000, "Phil Wheeler" wrote: Robin, Since you have a KX3, why the K2?

Re: [Elecraft] K2s
In my case, the form factor is a huge consideration. Having the knobs on the top makes sense for a trail-friendly radio that sits on your lap or a nearby rock, but it is not, at least for me, the best ergonomics for a base station. Putting it on a plastic tilting stand doesn't change that. Cabling is another big factor. I like cables coming out the rear, not sprouting from all sides. It makes sense on a TFR, but not so much in a base station where other gear abuts it. Believe me, I'm not knocking the KX3 as I've never owned or operated one. I've never even seen one except in pictures. I had a KX1 and it was always the last radio I picked up to take camping. (K1 was the first). It was more of a hangar queen for me. I just never enjoyed using it, but I never really used it as a trail-friendly radio which is what it was designed to be. The K1 was much more comfortable to use sitting in a campsite tuning the radio while I poked at the campfire. Based on form factor, the KX3 was never a consideration for me and neither is the KX2 (certainly the ultimate TRF) for the same reason. I have two K2/10s with KPA/KATU in EC2 box (SN567 and 6911), and just about every internal accessory. I didn't build any of it so the fun of building is irrelevant to me. I like them because they are very competent, reliable, wonderfully supported, even traditional radios that suit me. That's enough.

Re: [Elecraft] K2s
The K2 is unique! I built mine eleven years ago. It's still very much up to date. Of course I operate with a couple of Drake twins sometimes! I added the modules as they became available. I don't chase DX, or work contests (except field day) so I don't find any need for the K3. Now the KX3 is another story. It might be my intro into the next generation rig.

The K2 is a battery friendly, high performance, customizable, radio that is more compact than the K3. Because I built it myself I'd feel more comfortable troubleshooting and repairing it. Although the kit is complex, most of the parts are commonly available, relatively easily replaced, and the assembly manual is exceptionally good. There is component level support online, and if you live outside of the continental US you have much better chances of repairing it or installing modifications/upgrades yourself without the expense of shipping it across borders to have it cued up in the repair shop behind other units in for repair. There are other reasons to buy it, such as the challenge of building an exceptional kit, and so forth.

Re: [Elecraft] K2s transmitted phase noise
One of the main reasons touted by Elecraft for many years is the low phase noise presented on the K2. Some of the things that contribute to unacceptable phase noise levels can be attributed to incorrect alignment of circuits during build, inadequate shielding of CAT cables and bus interconnect cables. The K100 higher power levels will also have proportionately higher levels of 'corruption'. A damaged or poorly working interface cable from the K2 basic to the K100 bus panel can be picked up on the transmitted signal. Running a KW will certainly take any of the above and make it that much worse, hence a small almost unnoticeable tweak at the base level can make a big difference after 12 db of amplification.

[Elecraft] K2s in SO2R mode for SS CW
I had my first full bore outing with my pair of K2/100s in SO2R mode. They did an amazing job of not bothering each other when transmitting on adjacent bands. I augment band separation with a pair of I.C.E. 419 automatic band filters, but the K2s do most of the work themselves. It is particularly impressive when you look at my antenna system which consists of phased tri-band quads at 75 and 40 feet, a 2 element 40M yagi at 80 feet, a 2 element 40M quad at 60' fixed northwest and an 80M dipole at 70'. The K2s allow me to transmit (CQing) on one band of my quads while listening (search & pouncing) on adjacent bands of the same quad.at the same time. I've even cranked up an amp to test putting 1KW on 20M with no interaction, except for the direct harmonic, on 15M or 10M in any combination. This was particularly useful on Sunday in ARRL SS CW when pickings are slim. When transmitting on 40M, I can hear hash on 20M plus or minus the second harmonic, but signals are still copyable. I just CQ high on 40M (7030 or higher) and tune below 14060. Anyway, Elecraft has moved me up a level in the competition or at least help me stay even with the newer technology flooding the market. Being able to ignore high power stations planting themselves within 200 Hz or less of my CQ frequency really makes the stress much lower over the 30 hours when you are dead tired. In the low power category (150W), I managed 1025 QSOs in all 80 sections (if the North Dakota wasn't a pirate) in a rough year for SS. The K2s performed great. I did find an intermittent power fluctuation that I'll need to fix before SSB weekend. Oh well, gotta have something to play with, right?
