Re: [Elecraft] K1 Backlight a WINNER
Eric: The only problem I had was with the length of the LED backlight. Page 4 shows an illustration that says to cut it to 1-1/4, but doesn't say anything about having to cut it in the directions. Mine had obviously already been cut...poorly. It was cut at an angle and was about 1-1/2 long. This is a little too long for the space it fits in, but probably would work. I recut it squarely to 1-1/4 with a razor saw before removing the masking tape used during the original cutting. The mis-cutting is MY FAULT! And for that I sincerely apologize. Elecraft was anxious to get this mod out to users and I volunteered to cut the (K2) backlights into K1-sized pieces for them on my desk-top bandsaw. Apparently I must have mis-measured when I placed the center point on your backlight. Sorry about my error. Though I'm glad to hear you were able to recover cleanly. I'll be much more diligent in the future when cutting the next batch of backlight. 73, Tom HammondN0SS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Wally World et al survive and flourish because people - customers - take their business from the established stores and bring it to WW. The short-term gain is that WW can offer lower prices and a bigger selection. The long-term consequence is that local businesses are wiped out. And it's not just local businesses. The big chains dominate the manufacturers, forcing them to cut costs or lose the contract. (Look what WW did to Rubbermaid). They go overseas for products, forcing US manufacturers out of business. And then folks wonder where the good jobs went... Also in order to keep costs down, quality is sacrificed. Also serviceability, so that you have to buy a new one because the old one wasn't meant to be fixable. -- We saw a version of this happen in amateur radio 30-odd years ago. The old-line US ham radio manufacturers were mostly pushed off the shelves by imported rigs from Japan. The same happened in consumer electronics. Fortunately a few US ham mfrs. survive, like TenTec. The success of Elecraft is proff that at least part of the market looks beyond the price tag, at things like simplicity, performance, serviceability, etc. We don't just vote at the polls - we vote economically every time we buy something. 73 de Jim, N2EY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] OT: Public Service Radio
To all, I took the CERT training course last fall. I was the only ham from my town in attendance, but there were a number of hams from a nearby town (with a very active ARES and EMS community)there as well. I had a great time and learned a few things, but most importantly it confirmed for me that there are some EMS folks out there who recognize the contribution that we can make. The gentleman who taught the course is also the CERT coordinator in his town. He is very proactive with his volunteers in many respects. In particular, many in his group were newly licensed hams as a result of a course he ran after a presentation on ham radio by some local volunteers. After we finished the course, we were told to get in touch with the CERT coordinators in our towns and about the opportunities for additional training, and of course I did so. I'm still waiting for someone to return my phone calls and emails g. My point is not to discourage anyone, but if you can't get something going in your town, don't give up - some neighboring town can use someone with your skills. In my case, I think the CERT training was worth my time and I was surprised at how happy they were to have hams in their group. Every towns' emergency services have their own culture - some welcome hams, others don't. Don't be discouraged and keep looking until you find a good place. Dave WB2PJH From: Larry Makoski W2LJ [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] CC: elecraft@mailman.qth.net Subject: [Elecraft] OT: Public Service Radio Date: Thu, 08 Sep 2005 20:12:39 -0400 Fellow Elecrafters, Since Katrina unleashed her wrath upon the Gulf states; there has been a lot of discussion on this list and others about the value of Ham Radio and emergency communications. This post is not intended to stir up any controversy or debate; it's purpose is, however, to get you to think. We are ALL vulnerable to natural disaster, whether it be a hurricane on the south or east coasts. Blizzards in the temperature appropriate areas of our country, earthquakes and brush fires out west; flooding in the Midwest; or a tornado just about anywhere. When these things happen and devastation is widespread; your help is needed! We are seeing that this week more than ever. Please consider volunteering your time and talents. There are many ways you can do this. Hook up with your local Office of Emergency Management and see if there is a CERT program (Community Emergency Response Team) in your area. If there is none; then maybe there's a ARES or RACES group in existence. Where these do not exist contact your local branch of the Red Cross or Salvation Army as both of these organizations have letters of understanding with many local Ham radio Emcomm groups. The point is that Ham Radio is as valid and valuable as it has ever been. Maybe it's not done by Morse Code or maybe not even HF SSB anymore. Maybe it will all be done in your area with VHF/UHF FM communications or packet. Maybe Amateur Radio doesn't get the press that it deserves and maybe it's not as valued as it ought to be. But when all is said and done with Katrina, the stories WILL come out. You will hear instances of where communications systems failed and how Amateur Radio was the only way that rescues were performed, services delivered, families reunited. The ARRL had a slogan on their T-shirts for Field Day a few years ago, Amateur Radio - When All Else Fails. That has never been more true. But all that said, YOUR help is needed. Volunteer communicators are needed on a nationwide basis, starting with your own local communities. Get trained and be prepared. The best side benefit gained is the knowledge that you will receive that will not only help keep your community safe; but your own family safe as well. You folks who subscribe to this list and other QRP and Homebrew lists are among the most knowledgeable, brightest, most versatile, most adaptable, best trained Hams we have out there. You build, test and repair equipment. You set up and operate stations from fields, forests, oceansides, backyards, parking lots and even from inside EOCs. You are an asset to this country and its communities. For more information about CERT - please visit: http://training.fema.gov/EMIWeb/CERT/certfaq.asp Thanks for the bandwidth; and for allowing me to go off topic for a bit. 73 de Larry W2LJ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] WSJ article
There's enough blame to go around, but I'm blaming 1's and 0's. In my opinion, it's the root cause of the world changing. Some call this process Globalization. I know. I was there. I laid off hundreds. Then I got laid off. We can jam a lot of 1's and o's into a digital pipe and transfer it in nanoseconds. We call it bandwidth. It's much easier now for a digital receiver to read a signal sqare wave that goes up for a 1 and down for a 0. Now we have digital video and satellite T.V. And so can the poorest of nations around the world. Satellite T.V. for the economically poor-the 'have-nots'-opened up a window on the world. Now they saw for the first time what the have's really had, how they lived, their freedom and culture, and the cars and trucks they drove. Then the 'have-nots' decided they wanted some of this and a better life. So they decided to work for a meager wage and change. American companies liked this because their stock holders wanted the stock to rise and pay bigger dividends. Reduce labor costs was the mantra of the 90's. Send it to Mexico where a welder makes 2.50 an hour versus 23.50 in the U.S. In 15 years Thailand went from a rice producer to being the second largest producer of pick up trucks, and the fourth largest of motorcycles...in the world! We know where GM and Ford are right now, don't we? One night while watching National Geographic Explorer a shoeless peasant in the Amazon digging in the mud for gold nuggets walked to his grass hut to check the spot price of gold on the New York Stock exchange via the Bloomberg channel. Many of the 'have-not' countries can't get all the jobs from the U.S. or elsewhere, so are starting to get frustrated and mad at their leaders. The Middle East is a good example. Amy Chua calls it The World on Fire. Who would have imagined that a lousy 1 and 0 would have this impact on jobs and raw emotions. Demand is up for these developing countries because they was big shiny cars and maybe a pickup truck. Just like the millions in China are buying right now. If Wal-Mart where a country, it would be the third largest trading country in the world with China. The Chinese want oil from the same place we get ours. And the other have-not countries are going to want it some day too. More politics. See how 1's and 0's got us into this? Who would have thunk it? Then we hooked our computers to the Internet. More 1's and 0's running around the world. Instant post offices. Instant transfer of money to the have-not countries and withdrawl from failing countries. Instant drawing transfers and engineering changes. Take software development: In 1977 IBM was developing the same piece of software AROUND THE WORLD. Programmers from Beijing sent their work over the Internet at the end of each day to Seattle. Then they zapped it over the net 5,200 miles to Belarus in Latvia. From there it went to Bangalore, India who passed it back to Beijing by morning, back to Seattle and so on 24/7 in a global relay that never stopped until the project was completed.Think Ten Tec does this Have a manufacturing problem in a foreign plant these days? Just get on a video conference call. Sell your airline stock. NOW. Globalization, exporting of jobs, foreign investment, huge increases in demand, pressure from stock holders, Iraq, Afghanistan, the rise and fall of ham radio manufacturers in the U.S.: I'm blaming 1's and 0's. 73's DAve, KW4N _ From: [EMAIL PROTECTED] To: [EMAIL PROTECTED], [EMAIL PROTECTED],[EMAIL PROTECTED] CC: elecraft@mailman.qth.net Subject: Re: [Elecraft] WSJ article Date: Fri, 9 Sep 2005 06:18:56 EDT MIME-Version: 1.0 Received: from mailman.qth.net ([63.238.179.60]) by mc7-f20.hotmail.com with Microsoft SMTPSVC(6.0.3790.211); Fri, 9 Sep 2005 03:20:11 -0700 Received: from mailman.qth.net (mailman.qth.net [127.0.0.1])by mailman.qth.net (Postfix) with ESMTP id 7F6BA859C99;Fri, 9 Sep 2005 06:25:15 -0400 (EDT) Received: fromimo-d22.mx.aol.com (imo-d22.mx.aol.com [205.188.144.208])by mailman.qth.net (Postfix) with ESMTP id E1BD1859C14for elecraft@mailman.qth.net; Fri, 9 Sep 2005 06:25:06 -0400 (EDT) Received: from [EMAIL PROTECTED] imo-d22.mx.aol.com (mail_out_v38_r5.3.) id z.1e6.436c1583 (4222);Fri, 9 Sep 2005 06:18:56 -0400 (EDT) In a message dated 9/8/05 5:14:53 PM Eastern Daylight Time, [EMAIL PROTECTED] writes: Just look what the Walmart Super Stores and the Home Depot's have done to the local grocery stores and

Great order support from Elecraft. A local ham (WI6T) let me use his KXPD1 on Sunday, and I placed an order for mine on Sunday night. Got an email on Tuesday that said it was shipped. Arrived in the mailbox on Thursday. Got it built Thursday night and it works well (took a test run at 20 wpm, 25 wpm,30 wpm and 35 wpm with no sending errors and the paddle has a great feel).

I can't find any discussion of the distinctions between the 465b and the 465 other than a vague statement of improved electronics and the differences in panel layout.

OK, so what we know is that the path is continuous and likely OK - next thing to do is check the diodes in the wattmeter circuit - they could have been zapped with a static discharge. If you have 1N5711s in your bag of spare parts, I suggest that you arbitrarily replace them if there is any chance they could have been zapped. The other things that could cause low voltages in the wattmeter is T4 - there is really not that much else that could cause a complete failure to get a power level indication of some sort from the wattmeter. Check that all the leads of T4 are well soldered (there are 6 leads and one is the red wire coming from the SO239 to terminal 5, and the other is the bare wire to terminal 6). BTW, D16 is the only diode that must work to provide power control - D17 is for the reflected power. You may also have a bad connection to R26. One other thought that you may want to check for a voltage reading - the high end of R26 should show a substantial voltage (it does depend on the power output) if the forward power portion of the wattmeter is working - i.e. if diode D16 is OK and properly rectifying the output of T4. Check the schematic and I believe you can follow the circuit. 73, Don W3FPR -Original Message- From: Brian F.

Howard et al - Another option for you to consider: The Tek 7603 series plug-in scopes are substantially more versatile than a 465 or 475 series unit. Depending on the prices you are seeing for the 465/475, it is quite possible that you could find a 7603 at lower cost. Also, you can use 2 dual-channel vertical amplifiers (a pair of 7A26 units are a good choice) and a dual time base sweep generator (the 7B53A is the best choice here) and have a true 4-channel 100 MHz scope. 100 MHz is fast enough for most normal logic stuff, and the scope will still give useful response well past 2 meters for checking radios and such. You will also need a good set of probes. The best option overall is a set of 10X probes that have 2 meter (6.5 foot) cables. Unless you are working on modern (very fast) logic circuits, a 100 MHz analog scope will do virtually anything you might need. It certainly is good enough for the usual TTL and CMOS logic found in most ham gear.I There is also the storage tube version, the 7623A. It has a storage type CRT, very useful for slow sweep work, such as when using one of the spectrum analyzer modules (I have one for that purpose). The 7623A tends to be more expensive, typicially, about twice what plain 7603 units go for. It also has a smaller display area (approx. 7 X 9 cm) as opposed to the 7603 (approx. 10 X 12 cm), which is due to the storage tube. The 7623A has the same 100 mHz performance as the 7603. Disadvantages: the 7603 types are physically larger that the 465 series. Also bit heavier, but still easily transportable. Advantages: MUCH larger screen size. Good for old timers like me. But, here's the best part: Plug-ins! Available units include a very broad selection of vertical amplifier and and horizontal time base units, plus a set of very competent spectrum analyzers (the 7L13, covering 1 KHz to 1800 MHz is most useful for hams), a DVM unit, and even blank modules that you can build your own custom stuff into. Should repair ever be necessary, the 7603 is much easier to service than the 465 series. I have seen mainframes on Ebay in the $500 range for guaranteed good working condition, and vertical and horizontal plug-in units from $15 to $75, depending on model and condition. I have also seen much lower (and higher) prices at hamfests. The last 7603 I purchased (I now have 3) was $400 for the base unit, and $30 each for 3 plug-in units. I would stay away from the Tex 5000 series. They are good, but the 7000 series offer substantially better performance and the selection of option modules is much better. At surplus prices, the price difference is usually not enough to make the savings worthwhile. . You will never be sorry that you purchased a Tek scope. There are indeed some fine instruments from other manufacturers, but Tek is the Gold Standard when it comes to scopes.My personal test bench is almost all Hewlett-Packard, except for the scopes. IMHO, a clean used Tek is to be preferred over a new anything else. Just my 2 cents worth. - Jim, KL7CC Howard W.

Re: [Elecraft] News covering Ham operations on Katrina damage...
I called Mr. Gorecki to hear Motorola's side of the affair. I was referred to someone else, who is apparently handling public relations for this issue. He apologized for five minutes to me. (That was way more than I needed for my own satisfaction.) He said that the remark was completely taken out of context, and that they had received hundreds of calls, letters, and emails about the remark. He also said that Motorola want to issue an apology via the arrl.org web site, but haven't heard back from the ARRL leadership yet, possibly because many of them are also in the hurricane-damaged area helping out.

[Elecraft] KX1 Fuse Size
Hi-- I'm running my KX1 from a Vector VEC018 Battery Pack (http://www.vectormfg.com/catalog/vec018-pocket-power-p-72.html). It's actually a pretty nice battery pace. It comes with some nifty accessories and also is fused. The fuse, however, is a 10A fuse, and I'm thinking that maybe it should be a bit smaller since I only plan to use it with the KX1. I'm thinking 3A would be a more appropriate value. What say? 73! Dan KB6NU === President, ARROW Comm. Assn.

[Elecraft] KX1 Antenna Idea
Hi again-- Last night, I worked a guy who also is a KX1 owner, and we got to talking about antennas. I mentioned that while the antenna suggested in the antenna tuner manual (24-28-ft. driven element with a 16-ft. counterpoise) tunes up OK, I was kind of disappointed in the performance. The other guy mentioned that he uses a 40-meter doublet, usually in an inverted vee configuration, fed with ladder line, and that it tunes up well on all three bands. I asked him whether or not he used a balun, and he said no, he just fed it directly into the radio. I suppose his antenna could be fairly well-balanced or that the KX1 is able to tolerate a fair amount of imbalance. Whatever the case, I was thinking that it shouldn't be too difficult to build a small balun--and it really could be a small one since the maximum power level it needs to handle is just 5W--into a small plastic project box. On one end, the box would have two binding posts to connect the ladder line, and a panel-mount male BNC (if they make such a thing) on the other. Does this seem reasonable to do or is it overkill? 73! Dan KB6NU === President, ARROW Comm. Assn.

RE: [Elecraft] KX1 Antenna Idea
Hi Dan, I would just use the dipole. If you want a balun just coil up about 5 turns of the coax (use RG-8x) near the T of the antenna in about a six inch diameter and tape the coil together. I think that’s what Louis Varney (Mr. G5RV) recommended for his antenna. I have a picture of it on my 40 meter dipole at: http://users.ev1.net/~spituch/Steve's%20Page/Radio/Antenna/Antenna.htm Regards, Steve, W2MY -- No virus found in this outgoing message.

RE: [Elecraft] KX1 Antenna Idea
Dan, Actually, in my experience, the tuner could care less whether the load is balanced or unbalanced, it will just do its best job of matching the impedance it sees regardless of balance. OTOH, if you are concerned about radiation patterns, or 'RF-in-the-shack', it would be prudent to install a balun. For most situations (multiband use), I recommend a 1:1 balun over a 4:1 because it and the tuner will handle a greater variety of loads compared to the 4:1. The only important parameter that you need in a blaun is the ability to reduce or eliminate RF on the outer side of the coax shield (common mode current), and a simple choke made by coiling up a length of coax will do the job fine, as will the type with a ferrite beads on the coax (W2DU type). One thing that is certain, use a current type balun, the voltage type balun will not handle reactive feedpoint impedances very well, where the current type (particularly the 1:1 balun) will handle it much better (note that everything is a compromise when multiband antennas are addressed). 73, Don W3FPR -Original Message- Hi again-- Last night, I worked a guy who also is a KX1 owner, and we got to talking about antennas.

Re: [Elecraft] OT: Oscilloscopes
For a real versatile scope, I use a Bitscope made in Austrailia. It connects via USB to your computer and gives you not only a 100Mhz BW Dual channel scope, but a Spectrum analyzer and a Digital Analyzer as well. There is even a cheaper single channel scope available. I've owned and used several Tek and phillips scopes and the Bit Scope is truly excellent for the money. Professional quality.
