It won't win a beauty contest as i did some minor damage to finish in final assembly - but it works! If i had understood its concept of operations (e.g. paddle arms are grounded before contact) i may have saved some wear on it hi hi. I suspect i will spend a little more time perfecting the adjustments, but it works well. First two real QSO's with K5BT and K3WWP QRP ops, plus some 40m DX in between. I did add some more teflon tape before use and i may add some more. Now how to i hold this thing in place? I use it on a wooden surface. Has anybody developed an interesting approach? I think I taxed all my mechanical aptitude in assembly! Thanks again for the Az Scorpians sharing their project! curt wb8yyy __________________________________ Do you Yahoo!?

It's the ony way I'm going to get you all in there and get comments from each one before the band goes to pot on me. However, in spite of it all, it was a super net with 13 check-ins. Thanks to everyone for your check-ins and the relays from both Brian and Mikey helping me out with a couple of folks from the right coast. First up to bats: KB9BVN Brian An awsome signal tonight Brain. Thanks a bunch for being there and thanks again for the relay. KW4JS John Thanks for stopping by John. Hope to hear you again soon K1EV Bill Wasn't sure I would hear you at net time Bill. The bands was changing fast while we were working with Jim earlier. A little rough with the SSB but got you in there. Thanks for the check-in WB8ICN Mikey Hi Mike. Great to have you in there with us. I'm glad to see your getting some R&R Now, tell me what I need to do different to make the net better for everyone. It's frustrating not being able to get everyone worked. Now that my wx has turned winter, I can get out and do some antenna work to improve my end. LOL AF4PS Mac Top of the leader board in the WASP's A little rough at net time Mac but you jumped up quite a bit when calling CQ after the net. Go get dem piggies man !! WB5KHC Tom Real strong when you checked in Tom but nothing there when I got to you for comments. This band is nuts. Just can't tell what it going to do. K5LSU Jim Sorry Jim that I didn't get to you before we lost it. I know you wanted to get to that game. I watching it up here BTW. You guys are ahead right now. My fingers are crossed. C U L and thanks for stopping by W2LJ Larry You would have been a good signal in the clear Larry. The SSB folks just kept covering you up to a point I wasn't sure about your suffix. Thanks to Brian for relaying you in. AJ4AY Jay Always a good signal up here. Pretty rough this evening. Got most of your comments Jay. Thanks for hanging around and waiting until I got to you. N2JNZ George First time for me George. It was great to have you check in. But again, the dang ole band just couldnt' wait a few more minutes before it dropped out on us. WB4X Brent Brent is not a piggie but took a minute to stop in and say hello to everyone. A good signal from NC. Thanks Brent to you check-in and stop by anytime. KG4FSN Juan Good signal when check-in Juan but nothing when I got to you. The Pac 12 is doing a good job. Thanks for the QNI AWE a late QNI's just dropped by. K4YBB Jim WOW one of the best signals on the net tonight. Thanks Jim for stopping in. You've got the CW thing going your way sounds to me like. Keep up the good work and I'll catch you agian soon I hope. KE1LA Joel Our man from the great north east. Joel, I didn't hear you tonight. Thats unusual. Thanks to Mikey for relaying you in.

But even when we recognize that fact, we must wonder what is so attractive about them and why folks value them so much anyway. I'm afraid that even entertainment polls are more significant than we care to admit. Bill Walker wrote: > If you look at the numbers, the > total number of votes equals barely 1% of licensed hams in this country. Besides regular elections, I bet that the response to such a poll is still higher than any other correspondence that all directors received together on any given subject. Sure one can put greater value on fewer well written letters, but should only the folks who are not intimidated by such a form of democracy have a say? Of course the ARRL knows how to conduct surveys. They just collaborated with a member of this list to conduct a survey on membership issues. The irony is that only non-members are requested to respond. 73, --Alex KR1ST http://www.kr1st.com ------------------------------ Date: Sun, 04 Jan 2004 21:09:57 -0600 From: Rob Matherly To: fpqrp-l@mpna.com, qrp-l@lehigh.edu Subject: [164499] Neat stuff...

I use it under my paddles. Keeps them in place quite nicely. Also, in the cloth department of stores like WalMart, there are packages of little round rubber-like things. These are used on tools by folks who work with cloth to keep the tools from sliding around (my YF is a quilter). I use them on Altoids and other such enclosures that I build stuff in and under my J-38 straight key.

The DDS Daughter card uses one of the lower current oscillators, but even so, the higher in frequency you go with an oscillator, the hungrier it gets. Of course, the lower you go, the more ragged the sine wave gets, so it's a nasty tradeoff. Still, if you are looking for, say, a 5 MHz injection, then maybe a 40 MHz or so oscillator wouldn't be such a problem, and you would dramatically reduce the current consumption. However, it would take software changes, and probably wouldn't hurt to recalculate the elliptical filter, either. The 9850 can take some current, too, although I've never seen one eat anywhere near as much as their spec sheet says it does. Again, though, the lower the clock, the lower the current. DigiKey has a huge selection of compatible oscillators, although their selection is pretty weak on the >100MHz end. But read the specs really carefully. Some of those things are amazingly hungry. Hope this helps. 72/73 de WB8RCR http://www.qsl.net/wb8rcr didileydadidah QRP-L #1446 Code Warriors #35 ----- Original Message ----- From: "Mr Mike Caughran" To: "Low Power Amateur Radio Discussion" Sent: Monday, January 05, 2004 12:27 AM Subject: AMQRP DDS Daughter Card Questions > Q1: Is there an NT version of the control program? > > Can you use loaddrv and directio like in the elmer160 > documentation for FPP? > > > > Q2: What can be done to limit power consumption of the > daughter card? > > I was thinking of putting it into a qrp rig but 100 mA > is a bit high for the battery budget. > I tried dropping the supply voltage. > > Power out dropped with lowered supply voltage > until about 4 volts then the power raised back up. > Lowering supply voltage even more caused the > synthesizer to stop working. > Never did the current drop below 50 ma > > > Mike > KL7R > > __________________________________ > Do you Yahoo!? > Find out what made the Top Yahoo!

Message-ID: <3FF96A43.3900E6A8@amsat.org> MIME-version: 1.0 Content-type: text/plain; charset=us-ascii Content-transfer-encoding: 7bit Hi there, In order to get a clearer and more correct picture on how folks voted on the CW issue presented in that poll, one should not forget to only take into account the votes cast for retain/drop CW. You can not know how the folks who voted on the other issues feel about the CW issue ('cept that it plays lesser of a role to them). What this means is that you have to recalculate the percentages based on the population that voted on the CW issue. When I checked this morning, 3058 votes were cast to drop the code and 5052 votes were cast in favor of retaining the code requirement. The posted percentages are respectively 31.8 and 52.5. Recalculating the percentages for the appropriate population shows that actually 37.7% voted to drop the code and 62.3% voted to retain the code. Quite a difference. The way the poll is conducted and presented (btw, the ARRL does call these "surveys"), a minority can be shown in the results to retain the code requirement while that minority actually may easily represent the majority. And one should never present a link (option a.) to "favorable information" in any serious survey, which of course this isn't. Too bad that whoever composed the poll didn't include a link to their own CW information page ( http://www.arrl.org/FandES/ead/learncw/ ). I guess that page wouldn't attract new members, nor new funds. 73, --Alex KR1ST http://www.kr1st.com ------------------------------ Date: Mon, 05 Jan 2004 07:01:59 -0700 From: Jerry Haigwood To: QRP-L Reflector Subject: [164521] More Paddles Shipped Message-ID: <3FF96E57.9E2ACC38@swlink.net> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Folks, As someone on the list pointed out we have shipped more paddles (batch 3).

Can anybody tell me the size of the wire used to connect the arms to the base? Needless to say, I broke one of mine while sanding the base down to the required 1/32"... I replace it with another piece from my junk box, but I am almost certain that is too thick and will impede arm movement. I finally got enough coats of lacquer on the base to build the base back up to the original 1/4" thickness and am ready for some assembly. 73 de Lee km4yy/8 ----- Original Message ----- From: "Steve Smith" To: "Low Power Amateur Radio Discussion" Sent: Monday, January 05, 2004 12:18 AM Subject: Re: Paddle #186 QRV But How to Hold it in Place? > Curt, > > If you didn't wear it out while sanding, just use that square of shelf > liner that came with the kit.

I mechanically mounted my little driver/PA submodules in my fourth "Keep It Simply Sideband" chassis/module today, and interconnected some changeover relay cables to the other three modules, and----put the little KISS rig on the air for the first time. I used my lab supply to feed it 12.8-V. At that voltage, it draws 140-mA in RCV, jumping to 480-mA in XMT. Everything looked good on my Tek 465B connected across the SO-239 at the rig's output. Feeling lucky, I hesitantly broke into an SSB roundtable at about 3.85-MHz at 12z, and immediately caught the attention of KM1A, John in Connecticut. He gave me a 5 x 4 report from my QTH here in southern Maine. Ain't too bad for what I measure on my scope at about 600-mW PEP, eh? I calculated output power as P = E(peak)^2/2R = 8^2/2(50) = 64/100 = 640 mW. The REALLY exciting part of this milliwatt QSO was that the other members of the roundtable chimed in! VE3VKH, Ray, in Ottawa copied me clearly, and I also got "clear copy" reports from other ops (didn't catch their callsigns, as I was so excited logging this) on Prince Edward Island and New Jersey. This was VERY cool, I gotta say. Even these cats were excited. A few minutes later and a few kc up the band, I made another ssb QSO with WB1AIJ, Bob, in East Hartford, but he had a hard time copying me due to QRM, and then someone broke in to ask if he could call his friend on the frequency. The breaker made his call and then congratulated Bob on being a "great operator" because he let him break in----clobbering my QSO. Oh, well, what can I expect with a whisper QRP rig? Anyway, I made some JPEGs before and during final assembly, and when I put the rig on the air on my workbench, so I'll update my Web pages soon.

[military and metal??] Message-ID: <3FF9961F.A7C32B15@erols.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Chuck, I would be very careful about making such a blanket statement. Tubes, glass, metal, large, small, were in some ways still evolving when this country began its preparation for WW2 back in the 30's. The effort ramped up even further in 1941 when we became a serious participant. If you take a look at any point in time during the war you will see a very different cross section of equipment in use, equipment from the 30's that should have been or is now being phased out through brand new gear still in the shipping box. This will be true throughout the war years . If we look at equipment cross section of any day we will see gear that is first being used in applications, like high altitude flight or other aircraft applications where the design engineers may have initially thought a metal tube offered shielding not available in a glass tube equivalent. There was the effect of time on our equipment cross section too. As our technology improved tubes went from GT (glass tube) to subminiature. Metal tubes were easy to make and substitute for the very large, and large based tubes of the Octal era, but have you ever seen a metal 6AQ5? As technology marches forward many concepts fall by the wayside. What was standard equipment in the first old Curtiss aircraft flying at Pearl Harbor on December 7th, 1941, would have looked like tank equipment in a late model P-51 or P-47 being prepared in 1045. And there is quantity too. For the early years of the war we left nearly as much hardware behind on the battlefield as we managed to drag home. This includes men and material. Couple this with small inventories of everything and you might have one reason to suspect the metal tube was never made or is as rare as gold coin. But if you had been an assembler in a radio plant in 1940 you might have seen the picture differently. The wonderful surplus gear many of us cut our first teeth on was mostly left overs from late in the war. Yes, there were high volume equipment's when the war ended that found there way to the surplus market. Radios like the infamous Command Sets that we used in great quantity were of this category, and so was the J-38 telegraph key. BUT there were radios built before them during the war and radios built after them that were almost never seen. And add to the survivor pile from World War 2 came the Korean was surplus, and then equipment obsolescence, and the propensity of our military to not give away their equipment to the home hobbyist, but to give it to other Governments (allies).

Upon completion of the rehab, (cleaning contacts, realignment, tightening the handles etc.) I noticed that it was not staying put on the desk. A closer inspection revealed hardened and cracked rubber feet. I used rubber/vinyl bumpers used on kitchen cabinets applied to the bottom of the existing old cracked rubber feet. Lowe's sells a package of a dozen 1/2 inch diameter bumpers for less than $2.00. The addition of the bumpers will raise the stance of the paddle (1/16 inch or so) but WILL fix the scooting around problem. This simple fix will work on many different brands of paddles and bugs that suffer from slippery feet. I have used it on Bencher, Vibroplex and some homebrewed designs. The addition of the bumpers will provid additional clearance for the wire and allen wrench and clip in the Bencher.

The file DDS_Generator_Manual_Errata_v14.PDF has also been posted with a link on the DDS page, and it contains a corrected copy of only the two pages involved, plus a new cover page showing version 1.5. 72 Jim N5IB ------------------------------ Date: Mon, 5 Jan 2004 09:45:45 -0800 From: Mark Danner To: Low Power Amateur Radio Discussion Subject: [164538] RE: More Paddles Shipped Message-ID: <49B4D83BB849004A99F31EDE1237446B255547@mail.mfwi.org> MIME-Version: 1.0 Content-Type: text/plain Aaah. #319 looks is a nice number.

First of all, Randy Foltz, K7TQ has accepted the position of AmQRP Contest Manager. Randy, has several years experience as a contest manager, and we are very excited to have him join the AmQRP Club team. Randy will be responsible for scheduling and running all AmQRP Contests, and will also tabulate and score the results. Right now, AmQRP sponsors the NJQRP Homebrewer Sprint contest held in the early spring and and fall, originally started by NJ QRP Club, and the very popular QRP to the Field, originally sponsored by the NorCal QRP Club. All of these popular contests will continue, and Randy will be in charge of them for us. He will have announcements soon on other contests to come under AmQRP Club sponsorship. Randy will also have a regular column in the HOMEBREWER and a contesting section on the AmQRP web page. Ken Newman, N2CQ, will still be doing his very popular QRP Contesting Calendar, and will be working with Randy. I am especially happy to announce that several clubs, including NorTex QRP Club, QRPine (Maine), and the Arizona ScQRPions, have affiliated with AmQRP. What this means is that the American QRP Club is now a broad coalition of QRP clubs from coast to coast and we will be co-sponsoring the following QRP forums: Atlanticon, hosted by NJ QRP Club, Ozarkcon, hosted by Four States QRP Club, Hamcon, hosted by NorTex QRP Club, Lobstercon hosted by QRPine, Ft. Tuthill, hosted by Arizona ScQRPions, and Pacificon, hosted by NorCal QRP Club. Our dream of forming a strong group of affiliated clubs that work together to host regionnal QRP Forums has happened much faster than we ever imagined that it would. We have been excited about the success and growth of the club, and many ideas and programs are happening even faster than we envisioned. The local clubs, Arizona ScQRPions, Four States QRP, New Jersey, NorCal, NorTex, and QRPine all are very active. And all will be offering kits for all of you homebrewers out there. Arizona has their Paddle kits, Four States QRP has the Tenna Dipper, AmQRP has the PIC-EL kit coming in the next few days, New Jersey is doing the Micro908 Antenna Analyzer Kit, Rainbow Tuner Kit , the Atlanticon Kit, and the IQ-VFO Kit. plus NorCal has the NorCal Keyer, BLT, and the VE3DNL Marker Generator, NorTex has a kit coming in the near future, and QRPine has the Tuna Tin 2 kit. Kits from all clubs will be available at all QRP Forums this year, so you will have a tough decision on how to spend the money that you take with you to these events. Plus, exciting speakers and contests are planned for each event. The AmQRP web page will soon have a section for each of our affiliated club kits, so that you can go to one source for all of your ordering details. www.amqrp.org Membership signup for the AmQRP Club has been amazing. We have more than doubled our membership in less than seven months, and now we believe that we are the largest active QRP club in the US, with 1935 current members. The second issue of the HOMEBREWER will be showing up in your mailbox in the near future and we are very excited about the improved production quality of our journal. The AmQRP Club leadership team of Jim Cates, Chairman, Doug Hendricks, President, George Heron Secretary, Paul Maciel, Treasurer & Membership Chairman, and Joe Everhart, Technical Advisor, thank you for your support and patience through our beginnings. We could not do it without you. 72, Doug ------------------------------ Date: Mon, 05 Jan 2004 13:26:17 -0500 From: ed miller To: qrp-l@Lehigh.EDU Subject: [164540] Amplifier questions Message-ID: <5.1.1.5.2.20040105125917.00ab9458@mail.magnet.fsu.edu> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed To the informed ones: I am trying to build an amplifier for my DDS Daughtercard in order to get a +17 dBm signal out. If my effort pays off I will use attenuators of 10dB and 7dB to have levels for mixers and a 0 dB level for use with a step attenuator for general use. In my attempts to build an amplifier I have raised more questions than I have answers. Both of the questions concern an inductor in the collector circuit. If the 4:1 transformer has an Xl at a particular frequency why does it transform the 50 Ohm load up to 800 Ohms as opposed to transforming the Xl value down by a factor of 16? This fact is gleaned from EMIFRD. Also why is a step-down transformer used for impedance matching when it has a 4:1 voltage reduction? By my calculations this is a 12dB reduction, somewhat self-defeating. So far my results are not satisfactory. The wave form varies with frequency and I may have to go with a resistive collector load or maybe one of the MMIC's. I still need to vary the output so I can maintain a +17 dB level at the different frequencies. The DDS Daughtercard works perfect, it is my effort that is lacking.

Around 20 milliohms will do the job. Around 3" would be a nice length. If memory serves, 22 ga. copper is about right, but is light for the 15 amps that will sometimes be flowing. Also, the restance of copper is rather temperature dependent. Nichrome wire resistance is way too high. Are there any resistance wires that have low specific resistance and good thermal properties? I suspect what is used in analog meters is what I am looking for.

You might be able to drop 15 ma or so by eliminating the MMIC, depending what you'll be driving with the DDS. Changing R1 back to 3.9K will rise the raw output back up to about 1 v p-p, suitable for driving the LO input of a SA612. Any further reduction in current would require reducing the clock frequency and possibly replacing the 5 volt regulator with a 3.3 volt type. 72, Steve, KD1JV "Melt Solder" White Mountains of New Hampshire http://www.qsl.net/kd1jv/ ------------------------------ Date: Mon, 05 Jan 2004 13:42:09 -0500 From: John Sielke To: qrp-l@lehigh.edu Subject: [164543] Re: American QRP Club News Message-ID: <3FF9B001.9050300@pobox.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit > Right now, AmQRP sponsors the NJQRP > Homebrewer Sprint contest held in the early spring and and fall, originally > started by NJ QRP Club, and the very popular QRP to the Field, originally > sponsored by the NorCal QRP Club.

Let me first ask what is a QRP antenna? Or for that matter, what is a QRP antenna tuner. The QRP designation applies to input or output POWER. It has nothing to do with rigs or antennas or anything else on your operating desk. If I were you I would write that down and refer to it before you make another posting. I would have to say that a QRP antenna would be one that is incapable of handling more than QRP power- as in: http://www.eham.net/reviews/detail/3717 ---------------------------------------------------- A QRP tuner would be one that for either I squared R reasons, or voltage breakdown is incapable of handling more than QRP power A bit of a stretch, but one might define a QRP RX as one that draws minimal current (making it ideal for portable work) and/or only tunes the QRP calling freqs.

Well, in the recent issue of QEX, they decribe a class E/F 40M CW amp that runs on 12V, takes 5W drive & puts out 200W - all this with a volume of only 3x3x4 inches. I think this gives about 16 dB gain. As we say out west: YeeeeeeeeeeeeeeeeeeHaaaaaaaaaaaaaaaaaaaaawwwwwww! Those of you that have seen the article, how hard do you think it might be to make it?

To transmit, you will need to add circuitry to get a 170 Hz shift when keyed by a space signal. This could easily be accomplished by switching in a voltage offset to U1 similar to the way RIT is accomplished. However, I am not familiar with MMTTY and don't know if it, or any of the sound card RTTY programs have provision for direct FSK keying, as opposed to AFSK (they are normaly intended for use with SSB radios). That might be a stumbling block.
