Re: [Elecraft] Elecraft CW Net Announcement
Kevin: greetings from balmy Kona HI... beautiful place here... been up MUCH too long today and getting ready to crash (0645Z, 2045 LOCAL)... long (8 hour) flight... whew! Whipped. Did NOT bring ANY radio, so y'all have fun and I'll be a'thinkin' about ya. MAY(!) be back in time for next week's net, but no guarantees. 73, Tom Relay help will be most welcome since Tom is off basking in the tropics. He is likely having far too much fun to get on the air! Anyone with a strong signal may get roped into calling a few CQs tomorrow.

[Elecraft] Elecraft CW Net Announcement
Good Evening, Wow, it is already Saturday evening. Sometimes I wish I could get through my to do list before it expands. However, I thought up more to do than I could do in a month so I can't possibly get it all done in a few days away from work :) Such is life. The weather has been pleasant; the rains have slowed down to the morning mists from the ocean and the temperatures are in the high 60s to low 70s. I am not sure what it is like in the valley but I don't think it is much hotter than here. Soon we have our local airshow where I get to use a microphone for a day. Now to remember my callsign in voice :) I'll write it down so I can read it; I think that is the best way. I don't say it very often so I sometimes forget how. The local NCS on the VHF nets get a kick out of me stumbling over my callsign. There are a couple who know who it is from the pause! One of them told me to just say it in Morse and he'd write it down. The fox hunt was work this Thursday evening. The western op was easy but the one out east took nearly an hour to work. Twenty meters was not carrying his signal very well at first but gradually it got better so by 0220z I was able to hear him plainly. It took a few repetitions to get the exchange complete though. Tomorrow I hope the bands are better than they were then. Relay help will be most welcome since Tom is off basking in the tropics. He is likely having far too much fun to get on the air! Anyone with a strong signal may get roped into calling a few CQs tomorrow. Don't be shy, it is not difficult. Tomorrow: 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP help) Please join us: Sunday 2300z (Sunday 4 PM PDT) 14050 kHz Monday 0200z (Sunday 7 PM PDT) 7045 kHz 73, Kevin.

Re: [Elecraft] RE: K2 drops receive level
Maybe, but I experience the same phenom and do the same thing with key, It hasn't really been an issue, though. Would be interesting to know what does it though, I suspected something to do with the flow of info on data bus. I'd rule out antenna connection in my case because I have seen it on both ants and all bands and power settings. I'd bet a slight tweak on a NB or AGS setting or delay setting may clear it up.

I sort of agree and sort of disagree. I don't know if anyone other than the Elecraft team could have given us the K3 - or the K2, the K1, the KX1you get the idea. Maybe there *are* other folks out there who could have - but they didn't. Eric, Wayne and the rest of the team *did*. One of the key elements of the Elecraft story is that the team blends their own genius, experience and resources with the feedback from the amateur radio community - both Elecraft customers and others. None of their products is the result of ivory-tower design! The process includes those who will buy, build and use the rigs. Part of that process is sorting through the gripes and snipes and figuring out what can be included and what can't. Sure, a band-scope would be nice - but at what cost, in size, dollars and performance? All designs are compromises, and deciding what to trade off is one of the most difficult parts of any design, because no matter what decision you make, some folks won't like it. The thing I keep seeing in the "complaints" is that they're about minor things, not major ones. And often they turn into educational opportunities: no band stacking registers? Not a problem, the K3 has something much better. Another part of the process is that Elecraft products aren't really meant to be direct competition to other ham rigs. By that I mean they are built to a different paradigm, one that some will like and some won't. Remember when the K2 appeared, almost a decade ago? Who woulda thunk that a *kit* that cost almost $600 and in its basic form was QRP CW only would ever sell? Particularly one from an unknown new company with no advertising? 6000+ K2s later, it seems a slam-dunk > > I salute Eric, Wayne, et al for even having the ambition to start such an > undertaking. > Me too - but then again, did we not ask for it? > > Thank you, Elecraft, you are an inspiration for more than just your radios. > And they make it look so easy - even though it's not. 73 es TNX de Jim, N2EY ** Get a sneak peek of the all-new AOL at http://discover.aol.com/memed/aolcom30tour ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Second call: K2 broken after KPA100 mod
Don, Where is my more complete reply: The problem appears to be related to something loose aroud the MCU chip on the Control Board. If I put a lot of pressure on the top of the MCU chip, the ELECrAFTt message progresses to the frequency readout. This is with the Control Panel fully mounted and the KAF2 board installed. The connector cable to the KAT2 and KIO2 are disconnected for now. There are still some strange things, but at least the unit responds to front panel input. The pressure I refer to is with my fingers pressing down vertically. Remember the Control Board is installed vertically. The pressure is along the top row of pins. I also can use the foam handle of a pair of pliers, in case any electrical connection is made from my fingers touching the MCU chip. So far I've remove the MCU chip, with my wrist grounded, and touched up all of the solder connections on the socket. I also touched up all of the solder connections on the pins on that connect to the RF board. Again my K2 is serial number 2289. It has the mods from the document titled: "UPGRADING THE ELECRAFT K2 TO REVISION B". Also has mods from documents titled "ELECRAFT K2 REVISION 2 FIRMWARE" and "Elecraft K2 Keying Modifications Instructions". Those documents are with the paper included with this K2. 73, Steve N6VL -Original Message- From: Don Wilhelm [mailto:[EMAIL PROTECTED] Sent: Friday, July 27, 2007 11:00 AM To: Steve Kallal Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] Second call: K2 broken after KPA100 mod Steve, There is no direct relationship between your symptoms and what you intended to accomplish. So this is something that inadvertently happened along the way. The first thing to do is inspect the control board visually - in most cases an unsoldered or poorly soldered connection is to blame for behavior like that. Move things around a bit to see if you can make it change from working to not working. Also check the soldering of the connectors at the front of the RF Board - they provide a path between the front panel and the control board. Be certain the microprocessor (Control Board U6) is properly seated in its socket and no pins are bent under the chip (you may have to remove it to check for bent under pins - use good anti-static measures if you remove it). If the problem does not reveal itself visually, the next step is to do DC voltage measurements on the control board and possibly the Front Panel board. Compare to the DC Voltage chart in the back of the manual. Since you purchased a used K2, the level may be important - please let us know the serial number and state of updating that it may have had. I am sorry I cannot provide a more concrete answer, but it does have nothing to do with the KPA100 installation at the point where you are now. 73, Don W3FPR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Need local K2 help in Southern Cal...
Hi, I need someone locally in Southern California who can help me with my K2. I made a slight mod to the Control Board per the KPA100 manual and now the MCU appears intermittent. I need someone who can put my K2 on their bench, with me present, and help me find the a probable loose connection or short. I can get the front panel to respond if I put a certain amount of pressure on the MCU chip. The problem started after I removed pin 4 from P4 per the KPA100 manual. I must have stressed the Control Board somehow. I've already touched up many of the solder joints with a hot iron. I am looking for a different set of eyes.

RE: [Elecraft] OT: Keying contacts - Clairification
Kent K9ZTV, made the point off-line that burnishing (rubbing to smooth or polish) contacts on modern keys might not be a good idea. He observed that any abrasive rubbing or polishing might damage special finishes or alloys that the manufacturer may have used on them. I was speaking of my half-century old keys that have brass (or bronze) contacts that have been repeatedly ground and burnished to remove pits and burns caused by arcing when keying high voltage lines in old transmitters. As John mentioned, a reasonable current through those contacts actually served to help keep them clean. Modern very low voltage/low current keying circuits don't do that and the contacts easily become intermittent as they collect a coat of oxides and dirt. Such contacts need no such delicate care as perhaps modern contacts might, although it'd be foolish damage them further needlessly. (Some old keys do have silver contacts which should be treated with care, especially if they're plated and not solid silver. Silver oxide is a good conductor, so even if they appear black they are still good electrical contacts. If they become intermittent it's not because they are oxidized but because they are actually dirty with a film covering the silver. Very gentle wiping should restore good contact.) On my old keys with their bronze contacts, burnishing is definitely in order if nothing else works and they've survived that treatment hundreds of times over the decades. Recently I've found that De-Oxit does the job even better as I described. If I bought a brand new key I'd check with the manufacturer about how they recommend cleaning the contacts because, sooner or later, they're sure to need it.

RE: [Elecraft] OT: Keying contacts
I use De-Oxit. A drop between the contacts is allowed to sit there a few minutes, then the excess is removed by closing the contacts on a bit of paper. It solves the "dirty contact" problem for me. One treatment lasts many months. My second favorite method is to gently close the contacts on a bit of paper and pull it out to "burnish" the contacts but, for me, that doesn't work nearly as well or last as long as the De-Oxit treatment.

[Elecraft] PSK 31
I have had my K2 for over 6 months now and really enjoy it. I really use it a lot on PSK 31 mode and the reports coming back are a very clean signal. I use both HRD's PSK program (PSK Deluxe) and MIXW. Both programs use the CAT settings to totally control the rig. The audio interface was one I designed. Here is the issue: When I operate with HRD's PSK software upon occasion the K2 seems to stay locked in transmit after finishing a transmittion. The MIXW software doesn't seem to present this problem. under any conditions. Is someone else having this problem?

Re: [Elecraft] K2 SSB Problem
Fabio, I cannot be specific, but the most probable area causing that trouble is the area of Q2 and Q3 (those direct the BFO signal either to the balanced modulator in SSB mode or back to the RF board for CW) or the balanced modulator U5. Check carefully to be certain diodes D5, D4 and D3 are inserted in the proper direction and in the correct holes. 73, Don W3FPR [EMAIL PROTECTED] wrote: Hi, I just finished installing the KSB2 module on my K2 QRP version (full optional).

[Elecraft] RE: OT Dell Production Delays
Simon: WARNING: MISCELLANEOUS RAMBLINGS FOLLOW Anyone who places an order for and PAYS for a not-yet-released product should understand that s/he is entering the DANGER ZONE. Anything is possible, especially DELAYS and CHANGES in specs. To place a prepayment or deposit on a new product and expect everything to go "smoothly" is simply being naïve. Folks always have the other options to 1. wait until the product is released 2. wait until it has has received favorable reviews by those who already have it 3. wait X months after release until it is "proven." We each take our own risks. We each determine what level of risk any decision we make carries (whether we realize it or not). And BLOGS (including this one) tend to bring out both the best and worst in people. Once the ball (opinions) get rolling in one direction (currently "bad" for Dell), there is always the snowball (me too) effect. People LOVE to complain...ESPECIALLY in public. Luckily (at least in this country), one can always cancel if the product is not delivered within 30 days without penalty. In theory, the K3 might not be ready for Prime Time for another 6 months (yes, I did say IN THEORY). What would be the Elasticity of Patience (borrowing from economics) for the K3 before folks get "upset?" For me, since there is NOTHING else out there that I would rather have to replace my current radio (that I can afford), I'm willing to take my chances (of which there are potentially many). That said, I can "feel your pain" in waiting for your new Dell. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] RE: K2 drops receive level
Tim: I'm no K2 guru, but what you describe is classic of a poor/intermittent connection somewhere on the way to the antenna. I've experienced this with many radios, going back many decades. The "dit" (transmitting) somehow reestablishes a better connection at the point of failure. This might be at any coax connector (from the back of the radio all the up to the antenna). Try tracing your coax and connections along the way. Open up all contact points and "clean" them up (emery cloth, board, your favorite contact cleaner, etc). At the antenna (and elsewhere too), be sure your connections are not only clean, but tight. I'll leave the suggestions for what to "trace for" inside the K2 up to the K2-masters. de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
