Re: Re: [Elecraft] OT: News Article on Tin Whiskers Ruining Electronics
The problem with ROHS compliant soldering is that you must not be able to mix it up with leaded solder. So, a manufacturer has to have one or the other, or separate lines running one each exclusively. So, if the manufacturer wants volume production capability it has to move over to lead-free and dispense with leaded all together in a practical set-up. BTW, I don't think there are any cases of death by poisoning from leaded solder: it's now only a case of environmental issues (ie politics).

Re: Re: [Elecraft] OT - Two learnig the code tips
Your seating position is critical to long term comfort. I learnt this on a typing course back in days of old. The forearm needs to be horizontal, particularly NOT elbow lower. An adjustable chair is good. I much prefer a disc under the knob so that the middle finger presses on that and the thumb and forefinger just rest on the knob for guidance. The middle finger acts as a hinge against the larger movement of the wrist and arm which can move up and down an inch, whereas the gap might be only the thickness of paper.

With over 40 years of playing the piano, I do not need to support my elbow on the desk - that inhibits my control using wrist and arm from the shoulder action. I use a push pull action, two fingers on the top of the knob, thumb under, effectively gripping the knob. Proper training in piano teaches all the muscles used to relax whenever possible, no matter how fleeting a moment is available. It's superb training for the incidental ability to use a straight key continuously with an unsupported arm for hours.

[Elecraft] OT: re 2 learning the code tips
Ken said that using script is faster than printing. Not for me! I think it depends a lot on the size of your handwriting. I find that I can print tiny letters faster than I can write in script, which tends to get larger (again, for me). The most important factor (for me) is that I can always read my printed notes later (days, weeks, years later), while my script is nearly illegible even a few hours later. I have to work hard to figure it out. While I almost never hard copy cw anymore (not for many decades), I do take notes in seminars (and when I was in class for way too many years). Printing works for me! If I had used script, I would have flunked out during my first year of college. Currently, this is also the advise that I offer to the MD's in the hospital where I work (6,000 of 'em). Hand-written MD notes done in script are a dog to decipher. It is exceedingly rare to find MD notes (or any provider notes) that are easy to read when done in script. Printed notes are nearly always a piece of cake to read. MD's who have moved from large, loopy script to tiny printing love it and are real believers. Now if we could only convince them to type! Give it a try - you might be surprised! de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] first K2 problem
Dom, Look first for an unsoldered connection somewhere on the Control Board or on the Front Panel Board (the control board is the most likely place for the problem). Often unsoldered connections can work for several years before they develop enough oxidation to cause a break in what was only a mechanical connection. If you do not find anything unsoldered, start with DC voltage measurements on the Control Board. 73, Don W3FPR f6dro wrote: today I've got my first K2 problem after several years with no pb.

RE: [Elecraft] Just Wonderin'...
Hi Bob; That's correct, the 3CX1500A7 and D7 are completely different tubes. My remarks were from experience with the 3CX1500A7, the 8877. I don't know anything about the D7. If the tube is a 3CX, then it's a Triode (unless the coding has changed). If you're interested, you might have a look on the Eimac WEB Site. I think it's kept current. CPI and Eimac/Varian have business offices in Palo Alto, CA. Richardson is not the only vendor for the 8877. I don't know about the D7. pete, kn6bi -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of rrkrr Sent: Saturday, October 20, 2007 3:12 PM To: Robert Dorchuck W6VY Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] Just Wonderin'...

[Elecraft] Elecraft CW Net on hold unless ...
Good Evening from San Ramon, California. I spent the last few days driving to Pacificon and participating in the event. One last session of meeting and greeting folks at the banquet this evening and then I'll be on the road back home. No, I do not have my rig in my truck. I'll not be on the air until I get back home some time Monday night. It was fun seeing many of the folks I've worked on the Elecraft Net. Carter, N3AO, was very happy to see me. The most interesting meeting occurred when I talked to Wayne for about twenty minutes before he figured out who I was. I was wearing a bright red Elecraft shirt with my name, call sign, and NCS ECN on it. Must have been something I said which made him look closer at the text :) Eric took less than a second to determine my identity! Lisa was the fastest because she and I worked in an Elecraft booth a number of years ago. I also met Fred, Dale, and Chris. I am sure there were a few others but names and calls escape me. I have not slept very well since leaving home; cities have too much noise in them for me to rest very long. But, soon I'll be back on the mountain for the winter and will experience my peaceful retreat. It was very nice to meet and talk engineering with Lyle. Very interesting fellow. If you get the chance talk with him for a while. It was nice to hear a high level discussion of some of the design decisions taken while crafting the DSP module of the new K3. Later I heard some of the same from Eric while he was giving a talk at Pacificon. I will remember my visit to San Ramon and Pacificon for quite some time. If anyone wishes to start and run ECN tomorrow please take notes and send me the list of folks you worked. You should know the routine by now and know what to ask new folks. I'll do the writing if you wish so the lists and database stay in order. Then I'll send more gossip about the folks at the Skunk Works of Aptos! 73, Kevin.

[Elecraft] first K2 problem
Dom - I had the same problem. I turned the rig on. LSB, 75 mtrs - - No indication on the s-meter when I tuned the VFO, the frequency would not change. I unplugged everythingmicrophone, key, antenna. Then I turned the K2 back...all back to normal. The problem was my straight key. It was in the 'closed' position. All okay now. 73 de K5AVJ Lynn = Symptom: when powering the K2 , the elecraft text appears on the LCD , followed by the frequency where it was used before I got the pb . No noise at all in the AF , and no keyboard keys working , no S-meter = ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K2 - DSP - Impressive
David, Can you shared the settings you settled on, by mode? Especially include the Beta and Decay settings. 73, Steve N6VL K2 #2289 -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Wilburn Sent: Monday, October 15, 2007 4:15 PM To: Elecraft Discussion List Subject: [Elecraft] K2 - DSP - Impressive I have had the DSP for the K2 now for some time. I have to admit, I got the instructions out the first couple times I played with it, but I did not quite get it as far as the settings and the menu choices, and just kinda left things alone. Over the intervening weeks, when I would get on SSB to chat with friends I kept tinkering with it, and trying different settings (it didn't really seem to need to be fiddled with on CW). Eventually I had the thing so screwed up, that it was more of a hindrance than a help. So I broke down and printed out a section of the manual (I'm more of a soft copy kinda guy, but don't what to start that thread up again) and sat down at the radio to try and get the DSP back to all of its default settings. Now, as it turns out, reading through the manual, it is not abundantly obvious (for some of us denser folks) how to do this, but when I read a bit, and tinkered a bit, I worked through it just fine. Except for SSB #1 and the LowPass settings, I couldn't make that happen. Once I worked through all of the settings for each filter setup, I learned quite a bit. As many have said before me, this is a VERY impressive DSP. I did not fully understand the capabilities and settings till now. It is definitely worth the investment of time to learn. I even broke down and read through Lyle's Design Considerations for the KDSP. As always, great stuff. Thanks again Elecraft. Not only do you supply great equipment, but your documentation gives explanations of how the equipment works, thus we become more knowledgeable operators. Thanks, and great job! -- David Wilburn [EMAIL PROTECTED] K4DGW K2 #5982 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
