I bought the balloon at Edmund Scientific...actually, I used two balloons and put one inside the other for greater durability. The antenna wire was fairly lightweight, but adequate for 100 watts and the ends of the wires were tied down with 35 pound test monofilimant fishing line. The antenna was fed with 72 ohm twinlead (boy, I wish I knew where I could buy more of that!), which is also very lightweight. The apex of the inverted Vee was up about 100 to 150 ft and we got out like thunder! We were lucky, conditions were calm. It never would have survived windy conditions because the balloons are too fragile. As it was, the balloons stayed up for about 23 hours and 30 minutes. 73, Ken - VE3HLS Sharon, ON KX1 #112, FPqrp #716 >From: "pschweit" >Reply-To: pschweit@mninter.net >To: "Low Power Amateur Radio Discussion" >Subject: using baloons to raise antennas >Date: Sun, 11 Jan 2004 23:24:25 -0600 > >has anyone out there used a helium balloon to raise antenna elements . > >what sort of balloons and antennas were used? > >and > >what were the weather conditions? > >de K0CD >rob > _________________________________________________________________ The new MSN 8: smart spam protection and 2 months FREE* http://join.msn.com/?page=features/junkmail http://join.msn.com/?page=dept/bcomm&pgmarket=en-ca&RU=http%3a%2f%2fjoin.msn.com%2f%3fpage%3dmisc%2fspecialoffers%26pgmarket%3den-ca ------------------------------ Date: Mon, 12 Jan 2004 19:46:28 -0500 From: "Ken Alexander" To: mark.rauchfuss@worldnet.att.net, qrp-l@Lehigh.EDU Subject: [165156] RE: using baloons to raise antennas Message-ID: Mime-Version: 1.0 Content-Type: text/plain; format=flowed I think someone referred to a balloon that's meant to be tethered in place and would be ideal for supporting a longwire. They're called aerostats if I'm not mistaken. A few people around here use them for advertising, like car dealerships, etc. Therefore, it may be possible to rent them from someone for a weekend if you're thinking of a short term event like Field Day.

I finished the PC board and had gathered jacks and pots and a cast aluminum case, but stopped before getting it together. Fast forward to Spring of 2002, when the FT-817 and MP-1 lured me back on the air. I eventually dug into my boxes of ham stuff and found the unfinished kit. It took a while, but I found the manual and completed the assembly. However, at that time I was still "alignment challenged," so I sent the rig off to SWL's repair guy Steve, together with a request to expand the VFO range (a cap change). Both Dave and Steve were a great help, and I got the rig back aligned, with the requested mod, coax added between the board and RF BNC connector, and with a few "touch-ups" of questionable solder joints--seven years after I originally bought the rig. Is that great service, or what? (The fee was modest, too.) Unfortunately, as Steve pointed out, although the tuning range was wider, the power now dropped off significantly at either end of the tuning range because of the final bandpass filter. Somewhat disappointed, I put the rig away (I didn't even have an antenna for 80 meters) and a year and a half later I tried selling it at a hamfest. No luck. Again it went into storage, until two weeks ago when, suffering from serious solder fumes withdrawal, I got it out again. It was easy to replace the cap controlling the VFO range to a value slightly smaller than the original specification, and my alignment skills have improved considerably after building several rigs in the last couple of years. Result--a great little rig for 80 meters with 1.5 watts across the entire tuning range of 3.539 to 3.565. After nine years I finally got it on the air and had some great contacts on nighttime 80 meters, a band I've unfortunately neglected too long. I didn't even miss having RIT. I'm very happy that I finally got this transceiver kit in good operating condition, but it sure had to wait a long time. Do you have a similar tale? Can you beat a build time of nine years for one of your kits?

I'm trying to set up a QRP station in my dorm room....and having moderately depressing success. :-\ The station currently consists of the following: >Oak Hills Explorer II 20M tranceiver (my first HF rig, built from a kit several years ago) >38Special (with TiCK keyer; VERY well built by KT3A, and sold to me for almost nothing a couple of years ago) >ZM-2 tuner (built by Phil Salas, AD5X; sold to me at a 'college student discount' price a few weeks ago) >A random wire antenna (small gauge enamel wire, ~20-25' long, draped out the window) >A J-38 straight key (given to me by an ham in my old neighborhood) I'm having a couple of problems: 1) The Explorer II has been......well used. I managed to blow out (and had to replace) the final and driver a few years ago. The audio amp seems rather finicky (cuts back the audio and distorts). ...and it drifts constantly. (Oh, and the RIT function has ceased to work.....which may be just a result of a loose wire that WAS, at one point, attached to the front-panel "RIT" pot.) 2) The 38Special seems to be in fine working order.....but there is some VERY strong interference in my location, right in the middle of its tuning range. It sounds like digital/computer noise; it doesn't seem to vary much (if at all); and I'm guessing that it is a result of the 10baseT network, my fellow students' computers, and perhaps the TV cable and digital phone system wiring that runs throughout the dorms. (There are several hundred of us in a 14+ story tower in downtown Rochester.) Obviously, the Explorer is not working very well; plus 20M tends to be open when I'm in the middle of classes, rehearsals, practice, etc. With the interference on 30M, the usable tuning range of the 38Special is VERY limited. The up side is that the ZM-2 is working LIKE A CHAMP! (THANKS PAUL!!!) It seems to tune just about everything. It also tunes VERY FAST (...nice for antenna experimenting). A mentioned above, my current 'antenna' is a random length of ~24-26gauge enamel wire hung out the window with a coffee mug as a weight. It's not ideal......but nobody has noticed it yet (which is VERY important in this dorm). I'm running the random wire without a counterpoise right now. I tried hooking up to the hot water pipes for our radiator-based heating system; I tried a length of wire spread around my room; and I tried hooking up the the ground portion of my TV cable connection. All three seemed to INCREASE the amount of noise heard (on both rigs). Plus, the ZM-2 liked the setup better without the counterpoise. So I just tuned the enamel wire by itself, with the ZM-2's Link/GND switch in the GND position. Is there any point to dangling another enamel wire out the window and attempting to use that as a counterpoise? Is there somebody who knows the Explorer II who might be able to help me get it back up and running like it should be? Also, is there anybody around here (Rochester, NY) with a 40M receiver who would be willing to bring it over so I can find out if the interference is as bad on 40M as it is on 30M? (I'd rather not have buy/build another rig or kit until I KNOW that a band change will solve the interference problem. Plus....another rig would cost money......... Anybody need a violinist?) Any advice, suggestions or (ESPECIALLY) on-site assistance would be WONDERFUL. I have some basic test equipment (DMM, freq counter, etc.), soldering equipment, a few extra parts, etc.; but I'm a little tired of stumbling around on my own. :-| -- Michael F.

As originally designed, it is set up for LSB because the crystal lattice filter uses all 9.0 MHz crystals, and it was much easier to use one of the same 9.0 MHz rocks for the BFO crystal. Kinda hard to increase the frequency, so when you pull it lower with a capacitor, you get lower sideband (assuming low side injection). The frequency determining oscillator was a colpitts crystal circuit at 5.068 MHz, which when mixed with the nominal 9.0 MHz IF, gives an operating frequency of approximately 14.072, LSB. Using Digipan, set for lower sideband, this gives a PSK32 range of roughly 14.068 to 14.072. This is plenty of BW for normal PSK operation. After winning one of these little beasties in the Flying Pigs QRP Club's "Worked All Pigs 2003" contest for coming in third, and having built one of Trevor's DDS signal generator projects, I got this entirely hair brained idea to make the PSK-20 quite a bit more frequency agile and by doing so, make it quite a bit more versatile. After a bit of experimentation on my part, and a nudge in the right direction by Steve Weber, The mod to the older style PSK-20 rig (the one with the serial port, not the newest one that uses VOX. It should work with that one too, but the parts designators will be different.) First, build the PSK-20 per the instructions and get it working on crystal control. This will simplify alignment and insure that you are starting from a level playing field. Once you're satisfied that it's working properly, unplug everything, get out the soldering iron and desoldering braid or solder sucker. First, remove the 5.07 MHz crystal Y5 and it's trimmer capacitor C48. Jumper across the pads of C48 to give an easily accessable ground point. Next remove C49, C50 (the colpitts oscillator feedback capacitors), and R63. If you didn't break R63 when you removed it, solder it back into the circuit using the pads vacated by C50. This converts Q8 from a colpitts crystal oscillator to an emitter follower buffer current amplifier. Replace the old R63 with a .01 microfarad capacitor. Next, remove C51 and L7, jumpering the pads vacated by L7 with a small piece of component lead. Next, using a length of RG-174/U connect the coax across the pads vacated by the 5.07 MHz crystal, Y5. The center conductor of the coax goes to the pad that connects to the junction of R61, R62 and the base lead of Q8. The shield of the Coax goes to the other pad, or you can just solder it to the wire jumper lead you put in place of the Crimmer C48. The other end of this coax goes to whatever connector you use to get the signal in from the DDS generator. Trevor's DDS generator has the capability of programming a receive offset, and I used that to good advantage. After powering up the unit, I set the DDS to 9.0 MHZ (plug in a pair of headsets to J1, the MICR. jack and you'll hear the tone. Tune the DDS to just zerobeat that tone. Now set the DDS to SPLIT and tap the mem switch once to make the lower frequency designator change from a t to a T. This sets VFO B to whatever frequency you came up with when you set the DDS to zerobeat with the 9 MHz BFO crystal. Now, hold down the MEM switch until the "Select Menu Item" comes up and turn the encoder till you see "STORE RX OFFSET" Press the TS/OS switch once and you'll get "STORE RX OFFSET ARE YOU SURE?". pRESS THE TS/OS switch once more, and the 9 MHz frequency you determined will be stored as the RX offset. This will allow you to read your 20 meter frequency accurately in the DDS display. What you have done is set up HI SIDE injection at 23 MHz instead of LO SIDE injection at 5 MHz. This gives you USB and you will be able to listen to SSB stations quite nicely. Now, hook up an antenna and tune in either a fairly weak CW signal around 14.060 or a weak PSK signal at 14.070, and re-peak the RX front end L3, and the IF output transformer T1. It shouldn't have shifted much from when you first aligned it, but there will be a slight difference in LO injection voltage, so re-peaking may be necessary for optimum operation. You can now use it for pretty much all the sound card digital modes besides PSK-31, to include RTTY (remember to use reverse as you are now on USB and normal for RTTY is LSB), MFSK-16 (reverse applies here too), Hellschreiber, etc. For those modes that are sideband dependent, if they were designed for USB, leave it alone, if for LSB, use reverse mode. That's all there is to it. It took less time to do the mod than to compose this email.

Me, I use a Keuffel & Esser and a Post [Hemmi]. I prefer the Post, as the bamboo never sticks, while the K&E does have a tendency to. For all those that are going to inform me on how to 'lube' the K&E, it shouldn't be done. Get one that can do trig functions, but be aware some use degrees and some use radians instead. That plus log & ln functions ought to handle just about anything in the shack. There are also electrical and RF models that were available. As always, don't forget that Size Matters.

BUT.. at the same time, i changed the rig over to battery power.. i was having some issues getting a good ground match on my artificial ground, and i wanted to isolate whatever else may have been in the loop.. previously, i was using a radio shack 13.8 volt regulated power supply... (10 amp).. with a 2 amp fuse in series with the radio.. i switched over to the battery, and everything tuned up great.. and i was on easy street.. over the past few days, two people have told me that my signal was drifting in frequency.. as i was sending, i kept an eye on my freq, and i saw that it was indeed dropping during my end of the qso.. dropping about 300 hz in a matter of two minutes or so... in order to check this, i set up my memory keyer to send a cq beacon for a few minutes.. it was still drifting like crazy.. but only in one direction, lower. then, i decided to check the battery voltage ( that little voltage meter on the k1 is really sweet!) and found that it started around 12.7 and had gone down to 12.4 over a few days.. not too much to worry about.. so, in order to make sure i wasn't getting a weird reading due to the battery dying, i hooked the power supply. it checked in at 13.8.. that seemed right.. so i sent about a minute of cq's.. after about 30 seconds, i was back to the same old e42 error... i am sure if i pull it apart and goof around with it, i can fix it, but it seems kind of odd that it would start back up the minute i put the power supply back online.. next.. okay.. while i was tuning the radio up on different bands to see how it worked on batteries, i found that i was only getting about 2 watts out on 30m... i checked the menu to make sure it was set for 5w, and it was.. i moved it around a little bit both ways, in order to make sure it was not stuck somehow.. and it wasn't stuck.. but i could still only get 2 watts out. everything tuned up great, and seemed to be fine, but only with 2 watts.. i need help with all this .. can someone give me some pointers? ____ peace, ...sergio photographer, journalist, visionary www.village-buzz.com <- read my blog www.coffee-black.com <- my photography ------------------------------ Date: Mon, 12 Jan 2004 22:23:36 -0600 From: "George, W5YR" To: , "Low Power Amateur Radio Discussion" Subject: [165178] Re: Computing (was QRP Computers) Message-ID: <02a501c3d98d$03d431c0$0401a8c0@PS> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Every K&E I ever saw or used was made of cherry wood, Bruce.

I'm looking at a Hemmi bamboo model (from Japan), which is nearly identical to the K&E and Pickett rules I've used: C,D: basic multiply and divide scales A,B: squares and square roots K: cubes and cube roots L: common logarithms and powers of ten S, T, ST: sine and tangent (trig) functions CI: quick division CF, DF, CIF: multiply/divide by pi LL scales: natural logarithm and exponentials (base e) Since these don't repeat nicely for powers of ten, there are many of them: LL/3 through LL3 (eight scales) covers about .00005 to 20,000. More is better. Next check the mechanics. You want set screws so you can align the upper and lower fixed scales, eliminate play and excessive drag on the slide, and square up the cursor window. If screws are missing or stripped, it will never stay in proper adjustment. If the fixed scales are seriously warped (so you can't eliminate the slop without the slide binding, despite liberal applications of drafting pencil dust) you have a "collector's item": nice to look at, but not to use. Good luck, and have fun looking! 72, --Tim (KR0U) >Kevin M., W8VOS" : >So, if I wanted to pick one up from ebay, which one should I get?

Lots of awards including such things as paddle kits, Stinger Singer Frequency Counter semikits, ScQRPion pins, certificates and whatever else we can find that didn't sell at the last flea market. :-) Paddles will be awarded to the top multi op and multi-multi groups too. You guys will have to figure out how to award them within your own groups... No fighting. We're adding a new award category this year called "Just 'cause we feel like it." No rules for this one. We'll have a "Soapbox" section published with the results. We STRONGLY encourage relating your tales of trials, visits from Murphy, triumphs, woes, just plain hard work, bad luck, good fortune, arrests, out and out bragging, high misery to contact ratio, good deeds, or any other things you'd like to confess and get off your chests. Rules for last year are to be found at . Consider this announcement a preview as we have not updated the site yet with the final details. They'll be up soon with an announcement on QRP-L when that happens. Now.

I have some of them dating back to the 50's and 60's, and they are fantastic, especially for working on vintage gear. I'd love to have a complete set of handbooks on CD, and I'd be willing to pay a good amount for it. Besides, if they haven't transferred that information to digital storage yet, they should do so before it gets lost. Good suggestion Jim!

Boy, that brings back some memories! ;-) By the time I got into rallying (not just reading about it & wishing), we were using small handheld computers running BASIC or assembly language TSD conversion programs. Mine was the little Radio Shack job that had a whopping 16K of memory and I'd programmed it not only for the TSD calculations but to also keep our key time based on the conversions. It was pretty nice; keep the mileage matched to the computer's output (correction factor already input on the first leg) and stay on course! Easier said than done, of course... :-) I've still got that little thing laying around somewhere (complete with service manual); had to replace the case on it twice! I used it for a PDA before PDAs became the thing to have; it went into retirement one rainy day with big puddles when I was particularly clumsy. :-( 72/73, Don T.

Where the CD comes into it's own for me is at work; it goes along with me wherever my laptop does & isn't as conspicuous (read that "disappearable") as the hardcopy version. While I don't feel that the CD-ROM versions are the best way to go for the shack (nothing like that big, fat book sitting there on the shelf to inspire you), I do find them handy for travel AND for compilations of years of magazines. The "Ham Radio Magazine" & "QST" CD-ROM sets are good examples of this; years of great material at next to no storage space! I tend to print the stuff I want to read, though; my biggest gripe with this storage method is the eyestrain I get from staring at a CRT for any length of time. I always enjoy the articles & information in the magazines, especially the old ads & pricing information on the various gear that was available. A hamfest rat couldn't make a better purchase than those old magazine ads & equipment reviews to help figure out what that latest goody you picked up is! Doesn't everyone buy stuff that they can't identify just to further their education? If not, don't let my XYL know it! ;-) 72/73, Don T.

Yep, they were still issuing them then. I did some work with "photo interpretation" and we used - at that time - nice state of the art HP prgrammable calculators that had a mag card reader that you attached to the top of it. One day, the NCOIC of the section came around to all of our desks and gave us a brand new Picket 'rule that had a special scale on back for determining the size of the object on the ground - if you knew the altitude of the platform and the focal length, etc. We were told that "next week" there was going to be a class on how to use it - just in case there were no batteries available after the "big one". Well the class never was taught and it went in the bottom of my desk drawer and was never used. I must have put it in with a bunch of stuff when I got out of the AF in '91 and didn't think any more about it. I figured it was long gone by now. Well, I went up in the attic this morning to look for a book, and guess what - I found it! 12" Picket white aluminum still in the plastic in a leather case. Now all I have to do is d/l some docs on how to use it! I think the booklet that came with it is up there someplace, but not sure. 72 es oo Dennis - WB0WAO EN84ij Iosco County, Michigan MultiPig+ #3 - K2 #3555 DSW-II-20 - SW-40+ - SW-30+ RM-20 - RM-40 FPQRP #-347 FISTS #9299 Charter Member - Michigan DX Association www.wb0wao.com :=) _________________________________________________________________ High-speed users be more efficient online with the new MSN Premium Internet Software. http://join.msn.com/?pgmarket=en-us&page=byoa/prem&ST=1 ------------------------------ Date: Tue, 13 Jan 2004 11:43:28 -0500 From: Nick Yokanovich To: Low Power Amateur Radio Discussion Subject: [165214] Re: Slide rules Message-ID: <40042030.9000405@cablespeed.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit When I was a Navy air crew member, I often saw the navigator making calculations with a pepper mill.

I advised him of the facts of life regarding tuners and coax and suggested he select a non-resonant antenna length and feed it with balanced line.

I later found the non-review in QST from 1984 and remembered that was where I had first read about it. If you read it, you'll understand why it's a non-review. My friend thinks that, even though the maxx-com is mostly a resistor across the feed point, at least it will allow operation 10-80M. I say it's a dummy load, and would like to steer him elsewhere. So the problem remains. How does one feed a wire antenna appx. 132' long from near its center and get multiband performance without using balanced line? I'm tempted to suggest the trick of using two parallel lengths of coax with their shields connected together at each end, which the Antenna Book indicates is a possible solution, but I don't know anyone who has done that. =20 Any thoughts I can pass on? ------------------------------ Date: Tue, 13 Jan 2004 10:08:49 -0800 From: Bob Nielsen To: Low Power Amateur Radio Discussion Subject: [165222] Re: Slide rules Message-ID: <20040113180849.GC28389@bob> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline On Tue, Jan 13, 2004 at 11:43:28AM -0500, Nick Yokanovich wrote: > > I have here a different sort of slide rule that I found somewhere, a > Space Systems Calculator with a Collins logo on it.

There is a good article on that pepper mill (Curta calculator) in the current issue of Scientific American. They used to be the thing to have for road rallyes. All this slide rule talk caused me to look through my inventory. In the desk drawer I have a really beat up Pickett N4-T, an N3-ES, and an N-300ES, all in leather cases. I used to have a nice circular rule that had a slide out table of conversions. I really liked that rule but somewhere along the line I lost it.

Coax and maybe control underground, then balanced line to the feedpoint of the inverted v. The SGCs are supposed to work well in this situation. I have used the ICOM AH-4 somewhat like this, very satisfactorily. The LDG RT-11 was made for this purpose, although it needs an external balun. Unless you need to run really high power, it's good compromise, I think. Putting the tuner at the far end of the coax saves you the heavy coax losses at high SWR. Balanced line to the feedpoint saves you from having to mount the autotuner in an awkward place. 73 Frank AB2KT Farnes_Quinn wrote: > A good friend recently told me that he wants to erect an 80-meter size > inverted v, which he proposes to feed with coax and tune to operate on > all bands (10-80 M) with an antenna tuner. ------------------------------ Date: Tue, 13 Jan 2004 13:23:48 -0500 (Eastern Standard Time) From: "Mike WA8BXN" To: , Subject: [165226] Re: Antenna Dilemma Message-ID: <400437B4.000013.02852@etower> MIME-Version: 1.0 Content-Type: Text/Plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Yes, that snake oil box is a dummy load. Rather that parallel coax for feedline, use a single coax cable and multiple dipoles fed together. It works very well and if each is tuned to the part of the band most used no tuner will be needed. The original idea of using a tuner with the coax fed single dipole is not a horrible one if one is willing to accept the losses and power levels are such that the coax does not break down. A remote (real) tuner could be put at the point where the coax comes out of the ground and then feed with open line from the to the antenna.

Called the "Tektronix Circuit Computer", it calculated reactances and resonant circuits with elements from 1 nanohenry to 1000 kilohenries and from 1 millipicofarad to 1000 millifarads. The "R" scale goes from 100 milliohms to 100 megohms and from 1 cycle per second to 1000 megacycles. So you could read resonant circuits, along with Time Constant and Risetime for L/R and RC circuits for periods from 1 picosecond to 1000 seconds. All in an 8" circle. The K&E was reserved for cost estimates.......

I'm sure their SWR claims are correct-or close to it... you can take a 50 ohm dummy load and get the same figures... and pretty close to the same ERP. Tell him to forget... no... tell him to *FORGET* it. Your suggestion is a good one, except for the bit about underground. I have used a Bencher (AIR-CORE) balun with a G5RV for ALL band coax-to-OWL operation. It was awful on 30M, but loaded-and, more importantly-WORKED fine everywhere else. That does not include 17M and 12M because I didn't want to fool with figuring out the loading. At some point in time I'm fairly sure I ran some power into it without difficulty... but the bulk of the operating was at 50W output or less. G5RVs seem to like 33ft 6 inches of feedline... if he can get that much OWL/twinlead/etc. he can do one. (51 ft each side of center.) I don't know what to tell you/him if he has to go non-resonant but he COULD ignore losses/whatever, and just use coax, period. At lower power levels, his tuner ought to be able to match it. If I had his circumstance I'd do that... OR... 2) I'd put up some sort of loop. Resonant or not. Horizontal or Vertical. Same problem about matching applies (you can get a 4:1 balun and just that at the feedpoint), but at least it's more wire. (more wire GOOD!!! less wire BAD!!!) OR... 3) I'd try an end-fed longwire. Same matching problems plus a little, needs a better ground, and directional off the end as the freq gets higher. OR... 4) Get that ubiquitous vertical of some/any sort. With radials, Butternut is excellent. The much maligned GAP DX Voyager is KILLER on 40M, pretty good on 80M, and just OK on 160M. Also, Hy-Gain has the Hy-Tower HT-18 back in production. With radials, it's a champ. If no radials are desired, go with one of the compromises like the Cushcraft R-8 or the Hy-Gain DX-77A. With that range of choices, the best one for him it seems to me is just do the longest INV VEE he can, and feed it with coax. Next would be add as much OWL/twinlead as the height of his feedpoint would allow, and see what happens. Then just for fun, try that with a Bencher balun. P.S. If it's a metal mast he ought to standoff the OWL/twinlead from the mast as much as he can. ///snip >Next, he told me about an automatic antenna tuner made by >http://www.maxx-com.com > >///snip >So the problem remains.

Ladderline is cheaper, much lower loss and lighter weight than coax With a balanced antenna like a loop or dipole, there should be little radiation from the ladderline. I saw an old timer run some window line out through a metal framed window of an aluminum trailer during Field Day. He explained that as long as the window line ran out perpendicular to the metal frame there should be no problem. There was no problem. Some interesting reading: http://www.arrl.org/tis/info/pdf/9312070.pdf http://www.arrl.org/tis/info/pdf/9706057.pdf http://www.arrl.org/tis/info/pdf/49470.pdf http://www.arrl.org/tis/info/reflections.html I have read of tests by which indicate more loss under "wetted" conditions of window line. The same test showed, however that ladder line had no noticable change in loss with wetness. __________________________________ Do you Yahoo!? Yahoo!

This is the original "LDG AT-11 QRP Autotuner." This tuner is the same exact same size as the Z11. This particular unit was factory built (i.e., not a kit) and is in perfect condition. This is a full featured automatic (or can be used in semi-automatic mode) antenna tuner designed for HF (1.8 to 30 MHz) transmitters using 0.1 to 10 watts output. It uses a switched "L" configuration that works well with just about any type of antenna (e.g., dipole vertical, beam, ect.). Tuning time is between 0.1 and 3.0 seconds with an average time of 1.5 seconds. I have used it quite successfully with a Yaesu 817, a QRP-Plus, a NorCal 38 Special, and an MFJ 9040. I have used a range of antennas with it including dipoles, St. Louis verticals, and longwires (with a balun). My current rigs have internal autotuners and so this QRP AT-11 is available. The custom enclosure was made by TenTec. According to Bob Kellogg in a review on the QRP-L site "The QRP AT-11 automatic tuner was very efficient on all bands tested. In most cases one tuner setting would cover 1 MHz or more with less than 1.5 SWR." The QRP AT-11 autotuner requires power to make it cycle but the manual specifications indicate only a 0.1 watt minimum (not as low as the Z-11's 0.0 watt minimum, but VERY low all the same). Picture is available by email. The price for this "as-new" unit with the original instruction manual is $80 (plus $5 shipping within the continental United States).

There was no problem. My longwire, ladder line and window line exit my window between the metal storm/screen frame and the metal window frame. Only one exits at a right angle. They seem to work well.

If you have not gotten one now is the time. It has been a great kit but it is time to retire it. We may bring it back some other time but time to get working on the up coming Ozarkcon April 9,10, 2004 in Joplin, Mo. Thanks to all the people who purchased a kit from us and a Special thanks to Steve Weber "Melt Solder" , KD1JV for donating the kit to us.

I have not seen any posts related to lesson 6. So my problem may well be my problem alone. My questions are in reference to material presented on pages 8 -11. I read the text found on pages 8-11 of Lesson 6. I studied the underlying logic in the design of a program for multiple transmissions of the word TEST. I believe I follow the logic as presented on these pages. I downloaded the programming files for lesson 6 from the AmQRP web site. However, when I wish to build the files for use in the simulator I receive the error message multiple times. I checked the downloaded program against the text in lesson 6 and found one discrepancy...the
