Sunday evening I wi8ll be ordering enough to fill the orders I have, plus a FEW extra. I expect delivery in about 3 weeks. If you want one, order it now or drop me an email to let me know you're sending payment. The next order won't be for at least a couple more weeks. If you missed the original announcement, I am offering a directly attached memory keyer for the W5JH/ScQRPions paddles. This is a special board using the new Super PicoKeyer that bolts on without any modification to the paddles and provides a full featured keyer with two message memories, beacon mode, speed adjustment via pot and/or paddle/menu control, etc. You can see the full details at http://www.hamgadgets.com. I have all parts except the PCBs, which I will order in batches when there is enough demand. The kit includes ALL needed parts and should take well under an hour to assemble, mount and get on the air. Output is via a 3.5mm jack. Price for the kit is $18.00 including shipping anywhere in the US. Canadian shipping s a tad higher, total is $18.25. PayPal, checks, money orders are all good, as is cash - contact me privately if you have other goodies with which to barter, swap or bribe! 8-) 72, Dale - n0xas -- It's a thankless job, but I've got a lot of Karma to burn off.

EZNEC (and probably the others) think the end of the antenna has an infinite impedance and will tell you to move your feedpoint in from the end or do it for you. As I remember EZNEC does it for you automatically by moving the feedpoint in 10%-15% from the end of the antenna. If your primary interest is finding out the antenna pattern, the best proxy is to model a center fed doublet of the same length (halfwave, fullwave, whatever). The radiation patterns should be nearly identical with a true end fed. I second W5YR's recommendation: go download the EZNEC demo and try modeling your configuration as a center fed doublet. The modeling software can't comprehend your environment (fences, powerlines, etc.) but it'll give you a first order idea of what's happening. You can download it at: http://www.eznec.com . To your question, a 33' half wave on 20m has the directivity of a dipole when erected as a flat top at a particular height. If you lengthen it to a full wave, you will get the directivity of a fullwave where the pattern begins to split into lobes. Two full waves (132' feet) have an even more broken up pattern. You can see some of this at LB Cebik's site: http://www.cebik.com . For the 132' case see here http://www.cebik.com/gup/gup12.html Bottom line, lengthening the antenna to a full wave (or two full waves) can give you directivity/gain in certain directions. You'll need to look at the pattern for your antenna configuration (E-W, N-S, etc.) to see if the gain is good for you. Good luck! 72/73, *Lew* N5ZE ------------------------------ Date: Fri, 23 Jan 2004 10:59:04 -0500 From: "George Heron N2APB" To: Cc: Subject: [166087] AmQRP "PIC-EL Kits" ship today!

Sometimes I find EZNEC is good for me for getting patterns and then G4FGG program ENDFEED is good for checking efficiencies http://www.btinternet.com/~g4fgq.regp/page3.html#S301" The configuration of the wire plays a big role in the antenna characteristics (sloped, vertical, Inverted-L, end fed inverted vee, etc). Also as pointed out in Maxon's book HF ANTENNAS FOR ALL LOCATIONS try to avoid wl/4, odd multiples of wl/4 and lengths less than wl/4 as a rule. For repeatability I generally find the Inverted-L arrangement with equal legs a good choice. Additionally the equal legs help control the impedance values for multiband antennas. The 33 by 33ft proved on paper and in practice to be a good compromise antenna in way of loading, patterns and simplicity and repeatability of performance Alan KB7MBI in Woodinville, WA FISTS 5702 / ARS / Proud member of ARRL ___ ___ . . . . . . ___ ___ DIT DIT ------------------------------ Date: Fri, 23 Jan 2004 10:38:29 -0600 From: "Tom" To: , "Low Power Amateur Radio Discussion" Subject: [166090] Re: THE K2 AND AIRPLANE BUFFS Message-ID: <008b01c3e1cf$55858740$28f3fea9@n4rs> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Hey Joel.....I'm on the floor laughing......can't get up!!! ----- Original Message ----- From: Joel M Denison To: Low Power Amateur Radio Discussion Sent: Thursday, January 22, 2004 11:58 PM Subject: THE K2 AND AIRPLANE BUFFS > HIGH Y'ALLL > INSTALLED my k2 in my airplane and started flying with it.... > nice... > also found out the slower I come in for landings the closer I stay to the > start of the runway, instead of the other side... > also found out when u come in at 15 knots over stall speed u > better get ur flare correct or u will watch ur main gear flex a lot.... > unless of course u hit on the nose gear, which instantly becomes > retractable.... :-) > course now, dividing ur time between the outside, instruments and > the k2 can have u flying in funny positions at most any altitude.... > when ur dragging a 300ft wire outta the plane for the k2.... it an't no > time to geaux skimming power lines.... > ah but the dx... it's everywhere... nothing like a high > antenna...the trick is to keep ur landing gear from bending... > KE1LA > Joel Denison > Strong, Maine, 04983 > Freezin solid up heah > > ________________________________________________________________ > The best thing to hit the internet in years - Juno SpeedBand! > Surf the web up to FIVE TIMES FASTER! > Only $14.95/ month - visit www.juno.com to sign up today! ------------------------------ Date: Fri, 23 Jan 2004 09:03:08 -0800 (PST) From: Garie Halstead K8KFJ To: Low Power Amateur Radio Discussion Subject: [166091] Re: THE K2 AND AIRPLANE BUFFS Message-ID: <20040123170308.50164.qmail@web60302.mail.yahoo.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii --- Joel M Denison wrote: > HIGH Y'ALLL > INSTALLED my k2 in my airplane and started flying with it.... > nice...

I am working on two problems for the homework assignment...a desired receive frequency of 21.0 MHZ and desired receive frequency of 3.5 MHZ. I set up my program as a four byte/32 bit subtraction problem. With either of the two problems my program will always provide the correct answer for the two lower level bytes. However, with the 3.5 MHZ subtraction problem there is an error in the third (or highest level) byte required for an answer...desired answer H '159820'...my answer is H '169820.' The 21.0 MHZ subtraction problem is correct at the third level...H 'F56F40.' (I have not played with a problem that would require the use of all four bytes for an answer). At issue is the status of the C bit throughout the subtraction (borrowing) process for each of the bytes. I can create a program that will generate a correct answer for the desired listening frequency of 3.5 MHZ...but then there is an error in the 21.0 MHZ problem at the highest bit level...F4 rather than F5. Some suggestions would be appreciated.

How good are the antennas ?? Well, they arent mono band beams stacked at 100 feet but they do radiate. I wish I had had one when I lived in a Chicago highrise apartment in the early 70's. Im sure I could have made contacts. I could work hundreds of miles on VHF but never could get an 80 meter dipole to fit. :-) I played with a 40 meter Isotron in my basement a while back and I made contacts. I moved it out to my deck up 10-12 feet above the yard and I worked French Polynesia on 40. Also worked Cuba. But then I've also worked Europe on 80 meters with a random wire laying on my roof. If you cant do anything else it might be worth trying but the bigger and higher, generaly the better antennas work. 73 de Dave, N0IT ------------------------------ Date: Fri, 23 Jan 2004 14:50:21 -0500 From: W2EB To: crbink@sbcglobal.net, qrp-l@lehigh.edu Subject: [166100] Re: Isotron Antennas Message-ID: <40117AFD.5040105@twcny.rr.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit IMHO At various times, I've used the 10, 15, and 80 meter versions .....or should it be "tried" to use. After incessant tweaking, you'll probably get all of them to load up properly. You'll hear an active band too, but no one will hear you. Perhaps if you had excess power to waste, the antenna would be considered acceptable, but for 5 watts or less, these antennas are useless. A tuned piece of wire will leave you much more satisfied.

We did not know how quickly we could start this program, but it is going much faster than we envisioned. We have a model for supporting and putting on QRP Forums, and one of the key parts is funding with kits. You are supporting qrp when you buy kits from clubs, and the clubs could not put on these forums without your help.

I had the 40m & 20m models mounted in an attic and there was a -3db drop on the receive side. It was very difficult to tune the antenna. When I moved them out into the open, up about 12 feet above the roof line, the tuning is issue was resolved and they were about = on receive when compared to dipoles. The dipoles were 1 to 3 s units better on transmit. The Isotrons are a COMPROMISE (note that compromise is in BIG letters). Using purely unscientific comparisons (and my humble opinion) a full size dipole or even a hamstick type dipole would perform better than the Isotron antennas. --- crbink wrote: > I live in a apartment complex with a restricted antenna polices. > The garage > is attached and I have a 2 1/2" hole that goes into the attic.

A borrow from the next higher byte might then generate a borrow from the its next higher byte and so forth. It's possible for a borrow at byte 0 to propagate all the way to byte 3. Example: H'10000000' - 1 = H'0FFFFFFF'. Try this case in the simulator and see if it works. Anytime a borrow is needed you have to check the next significant byte to determine whether the borrow is satisfied (in which case you're done and don't need to check any more) or whether yet another borrow is generated causing the process to repeat with the next more significant byte. I might be completely wrong but that's what I'd check. :) Good luck! 72/73, *Lew* N5ZE ------------------------------ Date: Fri, 23 Jan 2004 14:20:16 -0700 From: "Gregg Olson" To: "qrp-l" Subject: [166109] Items for sale Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit I have the following items for sale that may be of interest to the members of the group.

It's a chemical treatment (not paint) that turns bare aluminum black ! Just buff the aluminum with steel wool, then degrease it with alcohol and apply until you get the degree of black that you desire ! You may be able to get it in the sporting goods at Wally World or at most gun shops. 72/73 de: Rick McKee, KC8AON <> Willow Wood, Ohio <> Grid: EM88rl SW-20+, SW-30+, SW-40+, Norcal BLT, Yaesu FT-7, Homebrew 6V6 tube TX QRP-L #2112, FPqrp #33, AR QRP, AmQRP, Ohio Valley Fists, MQFD #1 Monthly QRP Field Day info at : http://www.smartgroups.com/groups/mqfd Without CW, it's only CB !

They key idea being that having *audio* frequency analysis software in the soundcard equipped PC could be combined with ordinary receivers and the extra-ordinary signals from the NBS to read things pretty darn close. I decided to check out my FT-1000 and my W8DIZ frequency standard with this method. Part 1 is to verify (measure) the accuracy of the soundcard and software. Patched the receiver's line out to the soundcard and tuned in WWV on 10 MHz using AM mode. WWV transmits a variety of tones in AM at different times, but the predominant one and the one I used is 1000 Hz. My software read 1000.4 Hz, so I need to subtract 0.4 Hz from the reading I get in the next tests. Now to check the FT-1000. I put it in the LSB mode and tune to 10,001 kHz to produce a note (beat with the WWV carrier) of 1000 Hz. Here I measured tones of 1000.1 to 1000.3 Hz. So my receiver is "off" by minus 0.1 to 0.3 Hz, meaning it reads "low" by that amount. Not bad considering its readout is to only 10 Hz resolution. (And I don't have the TXCO.) Next, I go to a separate "in shack" antenna and listen to the frequency standard instead of WWV, doing the same test as above. Now I read 1000.1 Hz. Now it's a little tricky because I'm within the limits of repeatability. This little board is (to an accuracy of 0.1 hz) somewhere between "dead on" and 0.2 Hz off. That's pretty amazing. I had Diz do the adjustment because I didn't have (or know of) an adjustment method back when I purchased it. So it's been a number of months since the thing was set and it's been lying on my desk in a pile of junk since then. I guess this is pretty routine stuff in 2004, but it amazes me. "Back in my day" I was doing good to know my frequency within 10 kHz. Now we're talking less than 1 Hz. Coincidentally, an article appeared in this month's QST describing a method like this and one or two more. 72.00000, Nick, WA5BDU ------------------------------ Date: Fri, 23 Jan 2004 16:04:40 -0600 From: Chuck Carpenter To: thenels@go.com, "Low Power Amateur Radio Discussion" Subject: [166112] Re: Baking a BLT Message-ID: <3.0.2.32.20040123160440.0083a8c0@mail.9plus.net> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Nelson, I painted mine with a gray primer that is close to the Elecraft gray color. I baked it one time but my wife didn't l like that too much -- lots of paint odor in the house. Even though it's a primer, it makes a nice matt semigloss sort of look. It's quite durable when I let it harden for a week before installing parts.

My shack is in my truck and has used it for HF and VHF with no problems on phone. The only caveat is CW mode. The ic706 MIIG has a lot of audio output. Consequently when I send the side tone is very loud when I am listening to a Weak station. I must turn the volume just a hair from complete shut off in order to listen to my side tone at a comfortable level. I also wear hearing aids. I shut them off completely which provides an Additional 25 db of attenuation and can still hear the side tone well. Side tone that is too loud and is not much of a problem using a speaker instead of the headphones, but it is still loud. I looked into adjusting the side tone but with the rig mounted behind the passenger seat, I would need to remove the radio from its perch on the rear wall of the cab. Way to much trouble! Id' like to install a volume control in the cable supplying audio to the headset. It's on my list of things to do. BTW, Warren Gregoire and I are not related. 73 de AA1IK/4 Ernie Gregoire ------------------------------ Date: Fri, 23 Jan 2004 18:47:42 -0500 (EST) From: To: Subject: [166118] Re: End and Center Fed Dipoles Message-ID: <2495.192.168.1.117.1074901662.squirrel@gateway> MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit > > I looked up in the latest ARRL Antenna Book the End fed Zepp > antenna.

Hey Karl and the gang; Hmmmmm, where to start with the above. Well I do NOT necessarily agree with your statement in many respects, but to simplify things and make for a short response; One can easily make a feedline that is of a physical length so that it is NOT electrically a 1/4 wave (or odd multiple thereof) *appear* as an electrical 1/4 wave long. Some people call these "antenna tuners". So, there should be (usually) no problem achieving this "requirement" even when the feedline itself is physically of some other electrical length. As for the statement below: one can use coax, *AS LONG AS* one takes care to isolate the "third" path correctly, interchangeably with two-wire line to center feed a dipole. If the coax is large enough, it can actually have lower loss characteristics than (so-called) modern ladder line. It also has the additional benefit of stable loss characteristics in inclement weather whereas the modern ladder line has LOUSY loss characteristics when wet. Hope this helps and vy 72; Bob w9ya > > The Center fed antenna on the other hand is balanced so the > feedline will and should be balanced and thus will not radiate.
