[Elecraft] K3 observations from the reflectors
From the looks of it, at least 100 K3s are now on the air. A number of them have been through one or more of the major contests. Several have been on DXpeditions. There have been a couple construction related issues posted and I've heard one has gone back to the factory for a look see. Other than firmware changes, it looks like the rig will have minimal hardware issues. Firmware doesn't really sound like a problem to me. The fact that it continues to develop and improve is very positive IMHO. There are hams here that still have firmware issues with mature products from other manufacturers. Am I disappointed that I don't have the radio yet? Sure. Would I like more frequent updates than we have been getting? Sure. Do I understand why they aren't as frequent? Yes. Elecraft has had to do some things (winding toroids, if nothing else) they didn't expect to need to do. I'm not sure many companies would have taken that task on to keep product moving out the door. That alone implies that the technical folks had to check the non-technical folks work, time consuming, but guarantees that minimal defects creep into the product. Cool. In addition, they've added new staff to deal with vendor issues and regain some control given up by using outside vendors. It takes time to get new folks into the swing of things, even skilled labor. My faith in Elecraft isn't shaken. I've had conversation with folks who have K3s and whose opinions I trust and expect a great radio. I expect, if I do have a problem with my K3, that Elecraft will make it right (or better yet, help me make it right). Maybe I'll have to call instead of sending an email, whoop-de-doo. I see a few fellow contesters are picking up used K2s. I know a number of us are still very pleased with the K2 contesting mojo. I don't particularly like the turmoil on this reflector. Sadly, it's not unique to this reflector... Wishing all the peace that is supposed to go along with the season, regardless of faith.

Re: [Elecraft] KPA-100 QRP except on 80m
Don I've checked the bias voltages in TEST mode, both QRP and QRP, and they're correct for all bands. So the fault is clearly not a logic one associated with U1. So... the possibilities, I think, are a) T/R circuit, but I don't know why that should be band-specific b) LPFs, but QRP TX and RX is unaffected c) ALC The ALC could kill the QRO outputs on 40 - 10m, but an explanation of how it does it above 11W would be much appreciated. 73 Bob MM0RKT ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] HexKey
I have had my hex-key for quite some time and have enjoyed it. I opened up the original adjustments a bit, as the magnets were in contact. By breaking that contact, they are then 'floating in tension' and it gives it a nice feel. I have not had problems with the feet, but I use a little swath of anti-slip cloth, available at Wal-Mart, underneath the key. This mainly cause I am heavy handed. Most folks will be just fine with the substantial weight of the paddles keeping the thing in place.

Re: [Elecraft] KUSB vs K2
Hallo, Does anyone know conclusively if the KUSB USB to serial adapter listed on the Electaft website will work with a K2 and Vista? Regarding USB adapters: there are several variables, including the hardware and software of the computer, plus of course the adapter and its drivers, etc. So the answer has to be a resounding MAYBE. As far as Vista is concerned, I don't know. I've used various USB to Serial adapters for my K2 with Windows 200 Windows XP for years now and they have worked very well, and the KUSB is nothing more than an USB to Serial adapter, using afaik a widespread solution (chip) by Prolific http://www.prolific.com.tw/eng/support.asp. That said, shortly before my K3 arrived, my old Sony laptop decided it was time to go to the big bit bucket in the sky. My new computer is an Apple MacBook Pro, which allows me to run MacOS and, with Boot Camp, I can also run Windows XP Professional as a native OS. The KUSB mostly works with the Boot Camp/Windows combination and my K3. Unfortunately only mostly, because the Win-Test logger is occasionally confused by the data coming from the adapter, and some versions of the K3 firmware loader were not able to switch the baud rate as needed. These issues almost certainly have to do with the USB/Serial drivers running on my slightly unusual combination of hard- and software. I'll be doing some more testing this weekend. Bottom line: If the KUSB works correctly with Vista, it will work with your K2 and there is a very good chance that the KUSB will work well with Vista running on a standard hardware surrounding. One thing for sure, be VERY careful to use a cable between the K2 and the adapter that only connects the RS232 signals and not the K2-specific lines that appear on the connector on the K2. See the K2 manual for details. *** THIS IS IMPORTANT! DO NOT CONNECT THE KUSB DIRECTLY TO YOUR K2! *** You will need an adapter from standard RS-232 (KUSB) pinning to the K2 pinning. vy 73 de toby ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 USB-cable and Noise Reduction
I have been a happy builder/user of K3 for some week. Experience is that this is a real Elecraft-product: building was smooth; just according to the manual. A few problems arose, but reading the manual again corrected my own fault. KUSB-cable did not work at all. This may be a question of my own laptop. Replacing it with commercial series cable cured my problem. I was lucky to have RS232 still in my laptop. But KUSB is useless with me. I had a TS870 here before. I found it`s Noise Reduction almost useless for SSB. But on CW it was shining. Real marvel. Then I waited to see the same with K3. Nothing for me. Even the new version is not much better. I believe and trust that Elecraft will find a well working NR version for CW with time. K3 contains so much goodies, that I feel my learning curve is still in the beginning.

[Elecraft] K3: shipping - to the point
Hi there K3 owners-in-waiting: By this time, it must be crystal clear that the boyz in Aptos were irrationally exuberant in their projections of how fast the K3 would get out the door. It has recently been stated by the boyz that, effectively, we don't know. That is the most honest statement and one which I stated (and urged) here months ago. But the key phrase above is CRYSTAL CLEAR...which refers to the buyers. Every time I see a posting about a new shipping update I wince before I click on the link. But for now, that is all I do. It is what it is. I bought (ordered) the K3 because of (a) incredible specs, (b) my own experience with the K2, (c) personal excitement about getting a new rig, (d) UNREAL low price for what I would get performance-wise, and (e) disregard for my own well-established rules about buying a cat in a bag. Before I left for Dayton, I told my wife that I was going to buy the K3 and she said, No you're not. I laughed and said, Why not? And her reply was word-for-word exactly me. She said, 1. Nobody has one yet. 2. It hasn't been out one year. 3. It has not been reviewed by ARRL or RadCom. 4. You haven't played with one yet. 5. Fellow contesters, based on first hand experience, have not commented on its performance yet. Yup...I knowingly ignored over 40 years of rule-building when it comes to buying a new contest radio. I was psyched. At this time, I have chosen to sit it out because, quite frankly, there is nothing else out there that I would buy. It's a K3 or nothing. AND...for me, contest season is over for 2007 (save the Stew Perry Top Band) and I know that I won't my radio will not be here by then either. So further angst is now completely fruitless. So is getting pissed. I STILL WANT THE RADIO. I am not suggesting that those who want to comment on delivery stop doing so.

RE: [Elecraft] Power?
Yes, my K2's power output wasn't all that stable either. Power would shift around by more than I was comfortable with. When I went to the 100 watt power module, I'd see power jump from 70 to 100 watts and back. Turns out there is a side effect of the rig's design where the rig's power control logic has the least resolution on 40 meters and you can see some large jumps. In my case the solution was to change the value of one resistor. I can't remember which R but I do remember I got it wrong the first time (off by 10x) and the rig's power was wy down. Once I got the right value in there, the rig has been much more stable. It still jumps around a little, but so little as to not make any real difference.

[Elecraft] K3 00144 up and running; first impression
Instructions were well written, and well annotated. It went together smoothly without issues. At the mid-point, I powered the rcvr for calibrations and checks. I did so conservatively by powering it through a five amp fuse in a rig-runner power distribution strip. The next day i was ready for transmitter tests, and upon key down, blew the small fuse which I had forgotten about. When I asked K3Support for guidance, after all, i was in shock, I thought I had blown up my new radio, two things worthy of sharing took place: First, I had three answers in five minutes. Talk about support! (and i needed it in that startled moment) Second, each was incredulous. You CAN'T fry a K3. It doesn't happen. Check your power source. Yeah, sure right... Ulp. Momentary red face, then raucous laughter (my radio WASN'T fried). Found the fuse. Look. This radio is better than I ever dreamed a radio could be. And I could afford it. I am grateful to the consortium of engineers who are also operators who have created this thing, the conversations of the K2 users over the years who have all contributed to the detailing, and the hard work of those getting this kit out the door!

Re: [Elecraft] Power?
The resistor to change is R98 on the bottom of the RF board - increase the value. How much it can be increased varys from one K2 to another - it will never be greater than 1500 ohms, but some K2s can only increase it by a few hundred ohms. The best way to find the correct value for your K2 is to temporarily use a variable resistor in place of R98 (use 2k for best results). Increase the resistance until the maximum power on 10 meters decreases. When you have found the setting that does not decrease the 10 meter maximum output significantly, remove the variable resistor, measure it and install the next lower standard value resistor. 73, Don W3FPR Darwin, Keith wrote: Yes, my K2's power output wasn't all that stable either.

[Elecraft] K3 cult
Well, I received my K3/100 kit a few weeks ago. I bought it because of its outstanding technical specifications. Granted, the specs were not defined 100% at the time (last May) but the architecture of the rig spoke volumes to me (I am an electrical engineer with RF design experience). I don't believe that I am part of a cult. I just have a very good radio that just gets better almost every day! Who could complain? Not me! Elecraft is a small company that really cares and it tries to do the very best for their customers. Their people are polite and knowledgeable. I have enjoyed owning a couple of K2s and I have enjoyed building a few for others. Elecraft has brought pleasure to me and I look forward to enjoying more new products from them in the future. The world is becoming a more difficult place to live. Most of us are aware of the increased costs and the tension that brings. We get ripped off now and then and lied to frequently. It's worse for some than others but here we are and the sun will rise in the morning. It's nice to know there is a hollow tree in Aptos where hard-working, well-meaning people are making toys for us to enjoy! There IS a Santa Clause!

[Elecraft] QRP K2 FOR SALE...
Hello everyone, I have one-too-many rigs here at K0PQ, and I've decided to offer my QRP K2, S/N 1599, for sale to anyone on the list who might be interested in it. (My second K2, S/N 5615, is a QRO rig with the KPA100 amplifier and external KAT100. It's impossible for me to part with!) Here are the pertinent details: K2 S/N 1599 was purchased and built by me from its original kit form in January, 2001. It is equipped with the following options: 1. KSB2 SSB ADAPTER; 2. KBT2 INTERNAL BATTERY OPTION; 3. K160RX 160 METER MODULE WITH rECEIVE ANTENNA SWITCH; 4. KNB2 NOISE BLANKER; 5. KAF3 AUDIO FILTER REAL-TIME CLOCK; 6. VERSION 2.04P FIRMWARE; 7. KIO2 AUX I/O MODULE; 8. KSB2 SSB ADAPTER; 9. KAT2 AUTOMATIC INTERNAL ANTENNA TUNER; 10. MH2 MICROPHONE; 11. ALL VERSION A-TO-B UPGRADES. (These were purchased and added in January, 2006.) This rig has been a QRP favorite since I first constructed it six years ago. It has existed exclusively in a non-smoking environment and is 10/10 in appearance IMHO. There are NO scratches, dings or any other other blemishes anywhere on it or in it. It has been carefully aligned using Spectrograph. All of its filters are correctly set up. The rig comes complete with all connecting cables and all of its accessory construction manuals neatly cataloged in two loose-leaf notebooks. I will guarantee to the buyer that the rig will perform properly and will not disappoint you. I am asking $800 for the complete rig, its connecting cables and all documentation. If you are disappointed with the rig in any way, I will happily refund your purchase price in its entirety upon receiving it returned to me undamaged. I will ship the rig - - KBT2 INTERNAL BATTERY INCLUDED - - at no cost to you within the CONUS . If you prefer, I will be glad to remove the SLA battery and either ship it separately, or else reduce my asking price to you for the cost from Elecraft of a new battery should you wish to replace it with a fresh one. (The SLA Battery in the rig at the moment is only its second one. I keep it fully charged from my Rigrunner DC bus.) Please write to me off list if you are interested. 73 to all.

Re: [Elecraft] Mojo
I appreciate being able to fire up my K2 and enjoy whatever HF operating suits the moment. I can't say its clearly superior to other rig choices that could be in my shack, but it is there, and I assembled it myself. Original motivation was to experience the build, and use it as a QRP supplement to my higher powered rig. Then i discovered an interest in low-band DX - i wanted a rig with a receiver 'at least as good as a K2.' Well the other options were less affordable than upgrading my K2 (and I already knew how to use it, so i thought). So I am enjoying 80m propagation (which is quite interesting) with my K2/100 and a modest vertical. And I decided it's time for an autotuner for more seamless operating in the next contest (particularly on 80m where CW spectral use does expand up the band). Nice the same rig can QRP, as we have enjoyed using K2's in FD battery class (we had 4 available last year, and now another participant has built a K2 so now there are 5 around representing 3-digit thru the latest serial numbers. Yes a list that was once merely people who soldered their rigs together has expanded a bit. In 2008 the K3 matters should settle down a bit, and folk will continue to use and advance their K2's. These rigs are 'merely' windows into enjoying what propagation (and what antennas we can deploy) allows. So those of us with mere K2's or K1's or KX1's can continue to thrive. 73, curt --- Goody K3NG [EMAIL PROTECTED] wrote: I was away from this reflector for several years after I built my K1 (#505), just due to email volume and other things going on.

You'd hear of folks' first QSOs with a K1 or K2 or the gazillion miles per watt contacts or just everyday yet memorable contacts. You could feel the mojo.

[Elecraft] K3 CW Filter Tip
I have the 400 cycle 8 pole optional filter and was disappointed with the latest firmware to see NR disabled below 500 cycle width settings. My filter is in the FL2 position, so I went into the configuration and changed FL2 BW to 0.50. Now the 400 cycle roofing filter switches in at 500 cycles width setting and noise reduction remains on. The NR is truly amazing even at this narrow setting! -- 73, Bob Patten, N4BPPlantation, FL E-Mail : [EMAIL PROTECTED]Website: http://www.qsl.net/n4bp SOC #1 ARS #799QRP ARCI #3412 FISTS #7871 FP #1491SMIRK #6625 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] What's the K3/10 actual TX power?

Re: [Elecraft] What's the K3/10 actual TX power?
Kieth, You state that like it has been a major problem with your K2. If your K2 does not have greater than 10 watts on all bands, it needs some attention. Yes, the *maximum* K2 power will change from band to band because of the gain vs. frequency characteristics of the active devices. In general, a proper working K2 will deliver the greatest power out on 40 meters, but some others peak on 80. On those bands, I expect a K2 to deliver 15 watts at the maximum power setting. If you set the power request control to 10 watts, the power should level out to 10 watts on all bands. I know that does not answer about the K3, and I don't have mine yet to give input, but I do expect the K2 power control will be in smaller steps than the K2, and yes it should deliver at least 10 watts on all bands - if it goes up to 15 or 16 watts on *some* bands, that is not a problem.

Should I be concerned that I did not get 3.80 volts ? I'd say it is a little on the low side, but the error is less than 5%, so there is a good chance that it is OK. The target value is pretty much the end stop value when all components are at the centre of their tolerance bands, so around half of the K2s shipped are likely to be unable to reach the full 3.8 volts. In the case of the other reply, their 8 volt regulator was actually out of its 5% tolerance band. -- David Woolley Emails are not formal business letters, whatever businesses may want.

[Elecraft] New K3 F/W - MCU: V 1.49 DSP: V 1.46 NR Improved. AM added
We've been busy at Elecraft Engineering this week and we have just placed new K3 firmware on the ftp site. MCU: V 1.49 DSP: V 1.46 New Features: Noise Reduction significantly improved. Also, NR can be used with narrow filters in CW mode. AM mode added. (6 kHz Filter required.) NOTE: AM Power control temporarily works as follows: when you set power to 100 W in AM mode, it means 100 W *peak power*, and 25 W *carrier power*. Also, the bar graph shows peak power in AM mode. This will be corrected later so the display and bar graph both show carrier power.Manual notch frequency defaults to 2 kHz (originally 200 Hz). See 'Release Notes' in the K3 Update Utility for a complete revision history. Enjoy! :-) 73, Eric WA6HHQ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
