Since I am a man of leisure until Jan 5, I decided to try to work down the kit inventory on the shelf in the workshop. First to be assembled was the Az Sqrpion stinger singer frequency counter. I can't tell if it works or not. I power it up (no input connected) but I don't hear anything on the piezo speaker....no startup sequence, no freq readout, nothing. I modified the circuit to include an on/off switch and a power indicator LED. When power is the connected, the led comes on and all bias voltages are where they should be on the various components. Also, the piezo element is supposed to be driven by pin 3 of the 74HCOO. On the board I received, there was a trace leading from pin 3 to a through hole. Unlike the other holes on the board, this one was not plated. Similarly, there is a unplated thorough hole connected to the spkr output on the board. I suspect that there needs to be a jumper between these unplated holes. After my initial lack of success, I tried to connect a jumper directly from pin 3 of the 74HC00 but it still did not work. Bias voltages are OK and the passive stuff is probably OK. This pretty well leaves a bad xtal or bad ic's. Also, the piezo element that came with the kit contains 3 pre-soldered leads (not 2 as in the diagram). The supplied leads are too short and repeatedly pulled off when opening the altoids case to work on the circuit board. I eventually wound up replacing two fo the leads and forgetting about the third. Any suggestions would be appreciated.

I don't think there are any cheap paddles that are much good - good being smooth, especially at higher speeds. If inexpensive is the main criteria, I would get another J-38 and put two of them back to back in a vertical position. Seems to me that you would get a smoother paddle than with the low priced paddles (less than $60 & ++). Of the "small" paddles, it seems to me that Palm and Lil Paddlette are two of the better commercial ones. Otherwise I think I'd wait until I could afford something like Brown Bros, Kent, Vibroplex, Bencher, or something similar. 73 Hank K8DD ------------------------------ Date: Thu, 25 Dec 2003 16:13:01 -0600 From: Chuck Carpenter To: ve1dy@myway.com, "Low Power Amateur Radio Discussion" Subject: [163833] Re: Tenna Dipper Question Message-ID: <3.0.2.32.20031225161301.0069b04c@mail.9plus.net> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Paul, The dipper might be used to find resonance without the need to determine if it is matched. The connection to the antenna is one side of a classic bridge circuit. There are 3 known values and one unknown -- the input to the antenna. A null is indicated when the bridge is balanced by the unknown being equal. That is, when the input to the feed line is equal to the value of the three known resistors. In the dipper bridge, this is close to 50 ohms. The LED might not dim enough to determine resonance with the 300 or 20 ohm unknowns. If you changed each of the 3 known values to 300 or to 20 that might work. There are a couple of other values around the bridge circuit that might need changing too.

F. Johnson? Your key sounds suspiciously like mine. My key was made by Lionel, the toy train maker. Turn your key over and see if there is not an "L" in a circle on the back. here might also be "L's" in circles stamped into the brass base. E. F. Johnson made a key very similar to the J-38 for sale to the ham market as a new key. I have one somewhere without the bakelite base but I have never seen one mounted on bakelite. But the key is made entirely of "silver" base metal. The J-38 was originally made as a training key for the government. The original production runs were made by Lionel and Bunnell, I think. A third manufacturer made some production runs during the Korean Conflict, but the keys are nor nearly as well finished as the early WW2 production. I bought mine new in the box from Olson Radio about 1954-55. I paid the princely sum of 79 cents for this jewel! By the way, so far as I know the J-38 never saw combat use. Too many moving springs and things. In combat they would only get lost! So, please fill me in...

Lionel manufactured model trains at the time. I have an original Lionel model which I bought when I was first licensed in 1956. I paid 79 cents for this "key that filled a thousand dreams"! I believe the Lionel to have been among the best finished of al the J-38's. This was probably due to their experience building model trains, where finish is next to godliness! The reason I see behind their smooth action is they were made to be used as a training key. They trained hundreds of young radio operators! I also gave heard that there was another production run to support the Korean Conflict trainees. These may be the Artec keys. I gave a second J038 if undocumented ,anufacture and can say the action is nowhere hear the Lionel's. Lionell also made some of the J-36 bugs. This was a design by another bug manufacturer. I have a Lionel which I bought because it weny with my J038 and because I am a ,odel train enthusiasr. Unfortunately I only vought this about 1005. They had suffered some appreciation by then, I had to pay over $100 for it! 73 ------------------------------ Date: Thu, 25 Dec 2003 18:27:49 -0500 From: Bruce Muscolino To: jsielke@pobox.com Cc: Low Power Amateur Radio Discussion Subject: [163836] Re: straight key before paddle? Message-ID: <3FEB7275.26C0AB5E@erols.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Ya know, this has been a significant thread for me. I learned on a straight key, a J-38 in fact. I went up through the bug to a keyer and paddle. In fact I went through a single lever paddle to an iambic paddle. I am definitely "old school" having learned CW when radios glowed in the dark so you could find the rocks! I used to think that if you didn't learn on a straight key you didn't know CW. This thread and the postings I have made in response to them have caused me to rethink that position. The reasons I used a straight key had very little to do with learning. They had so much more to do with availability and economics, and the fact that back then no one used the words Novice and bug or electronic keyer in the same sentence! Now it makes very little, almost no, difference to me which is used to teach or learn the code. I will admit to a slight feeling of superiority at my skill with a straight key. I feel that my experience with the straight key and the bug make me a more complete CW operator (what else is there). BUT in the end the only important issue is whether you got enough off the air practice with your weapon of choice before you cluttered up the bands! 73 ------------------------------ Date: Thu, 25 Dec 2003 18:42:05 -0500 From: Bruce Muscolino To: myetsko@insydesw.com Cc: Low Power Amateur Radio Discussion Subject: [163837] Re: Study of Morse code...another view Message-ID: <3FEB75CD.971C39A6@erols.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Mike, > > Now with the relaxation of CW requirements, there really IS > justification for learning 'right', and learning so that you can advance > as the criteria more than just 'getting in'. > P don't understand your argument. Are you saying that any of us old timer's learned the code just to "get in"? Why then didI waste all that effort to learn and pass the 13 and 20 wpm test? Or are you saying that today's learners are not just as likely to "get in" with 5 wpm. While I believe that good CW operators can be taught, after all I think I am pretty good and I'm almost entirely self taught, I believe the important issue is whether the learner has any interest in CW. After all, I could have dropped learning the code at any time in my first 25 tears and bought a microphone. But I was never able to figure out how they worked! Please enlighten me... 73 ------------------------------ Date: Thu, 25 Dec 2003 19:07:53 -0500 From: Bruce Muscolino To: kg6cyn@softhome.net Cc: Low Power Amateur Radio Discussion Subject: [163838] Re: Study of Morse code...another view Message-ID: <3FEB7BD9.BADD6B1A@erols.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Pardon my ignorance. I thought everyone who wanted to learn the code knew they had to learn it by sound. That's how it is used. That's how you hear it on the air. It stands to reason that's how you have to learn it. If you were going to be using it on the bridge of a ship you would best be served by learning it by sight! Now spacing and speed are different things. Until about the mid 70's the standard was to teach the code at about 5 wpm. Spacing could be anything from 5 wpm to 1 character per day! Yes there were some studies in teaching at a faster speed but they didn't catch on until after the mid 70's so far as I know. Spacing could have been at character speed or using farnsworth. I learned at a slow speed and used the farnsworth method until I knew the entire character set and was ready to start copying off the air. I believe that copying off the iris the only way to really learn the code. That way it comes complete with QRM and QRN, just the way you will use it! I believe computer generated learning systems are just that, learning systems. They are useful until you know the code, then switch to a receiver! The code is simple yet complex. Too many people, myself probably included, have made it more complex than it should be! 73 ------------------------------ Date: Thu, 25 Dec 2003 19:20:00 -0500 From: Bruce Muscolino To: kr1st@amsat.org, qrp-l@lehigh.edu Subject: [163839] Re: straight key before paddle Message-ID: <3FEB7EB0.8809BA0@erols.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Alex, There is only one method of developing a fist you won't be picking out of your eye. Practice off the air until you can send 5 minutes of perfect CW without making an error. Then, and only then, should you go on the air. Would you go off to war without a thorough understanding of, and proficiency with, your rifle? I believe this concept has been discarded from most learner's guides.

You do not need to change all three resistors, just the one on the antenna side, as I think you are hinting at. The LED will go out when it sees a load matching the selected resistor. Switching in several difference resistances might be physically difficult. Once suggestion would be to steal some machined pins out of a nice IC socket and use a pair of them as a plug in socket for a selected set of resistors. - Dan, N7VE >If I wanted to use the tenna dipper to find the resonance of a >folded dipole, could I change the 50 ohm resistor to 300 ohms >and then look for the led to dim? > >If I was looking for the resonance of a mobile antenna and >figured the impedance to be around 20 ohms, could I change the >50 ohm resistor to say 20 ohms and then look for a dip. > >I was thinking of a variable resistor or several resistors on a >switch.

The bridge has three nominal 50 ohm resistors plus the unknown input as the fourth leg. So you'd change R5, R6, R7 to 300 ohms, 20 ohms, or whatever. Actually though, all four legs don't have to be equal to get the balance, just the two pairs that are symmetrically opposite. So I guess you could just change R7. Is that what you had in mind? The interesting question is, where (in terms of impedance) will the bridge null out if you don't change the circuit and the input is 20 ohms resistive at resonance? At 50 ohms, or at some other value? Hmmm ...

Bruce, I would venture to say that J-38s were produced by dozens of manufacturers during WW-II, not just 2 or 3. I've owned several Lionels and in my opinion they're OK but don't hold a candle to the J-38s made by those companies who were actually in the business of making keys such as McElroy, J.H. Bunnel and Signal Electric to mention just a few. Don't get me wrong, the Lionel is a good key but I think it's reputation comes more from the name recognition rather than the comparative quality. Be that as it may, in my opinion any CW enthusiast should own a J-38. They're historical, rugged and generally good telegraph instruments. Since millions of the things made, there are still plenty of 'em available out there on the used market at reasonable prices, even on the auction sites. Within the last month or two I've seen some for sale that were in fair, restorable condition for less than 15 Dollars apiece. The majority of J-36 keys were either Vibroplex Lightning Bugs or clones of the same, the most popular and recognizable being the Lionel. The Signal Corps J-36 was a designator for "bug" and not a specific design. It is interesting that some "bug" manufacturers, such as Bunnel, sold not only their own bugs to the government as J-36s but also manufactured clones of the Vibroplex design! I'm curious, what version Lionel J-38 do you have? 73.......Steve Smith, WB6TNL/0 Hoxie, KS "Snort Rosin" On Thu, 25 Dec 2003 18:12:13 -0500 Bruce Muscolino writes: > As I said in an earlier message, the original WW2 production of J-38 > keys was split up among two or three different vendors, Lionel > Manufacturing being one.

If I wanted to use the tenna dipper to find the resonance of a folded dipole, could I change the 50 ohm resistor to 300 ohms and then look for the led to dim?

If I was looking for the resonance of a mobile antenna and figured the impedance to be around 20 ohms, could I change the 50 ohm resistor to say 20 ohms and then look for a dip.

I was thinking of a variable resistor or several resistors on a switch. Is this practical?

Thanks and Merry Christmas to all.

It was real easy to fix and now works FB and looks like "new". It doesn't have a name plate on it, but it is a Lionel (they are the only ones that had 5 "pins" to hold the nameplate on the base). The nameplate on the Lionel J-36's was some type of plastic that was not "stable" and most of them have long since disintegrated.

It came ready to use out out of the box. I have owned my first key, a Lionel J-38, since 1956. That makes it, now, going on 48 years old, and it is as smooth as ever. The finish is nearly as good as it was when I took it out of the box. I have owned and used other manufacturers J-38's. I find them hard to adjust and maintain their adjustments. Personally, I don't like them as much as my Lionel. YMMV. A key, to me, is a close personal item! As to J-36's having nameplates that were unstable, I believe this is folk lore. I am only going on a sample of two, but they both had nearly perfect plates. Mine is one of them. The nameplate is not immaculate, but it is there, complete and legible. Perhaps the gentleman I bought it from had a nameplate fetish. Mine also has the cloth covered tinsel wire cord and wedge attached. Perhaps these were responsible for the price (over 100). Also remember I bought mine in the pre ebay era. 73 ------------------------------ Date: Fri, 26 Dec 2003 09:38:55 -0500 From: Dan Wolfe To: qrp-l@Lehigh.EDU Subject: [163854] Re: WTB: Wilderness Sierra Message-ID: <3FEC47FF.3D63@mounet.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Howdy Tim, I have one of the Wilderness Sierr Radios that I just do not use any more.

I have owned and used both single and dual lever paddles. I believe to be effective a paddle (or straight key for that matter) must either be largish and heavy or firmly mounted to the operating desk. A key or paddle that "walks" all over your operating table does not promote good code. Look at photographs of commercial CW stations, or old ship's keys, or military strains. Now, about single lever paddles. I own and have used the Vibroplex. It is like using the back end of a very fine bug! It is also very heavy. I could never really get used to it. I switched over to a Bencher BY-1 which I find ear sir to use and adjust. I do not use the BY-1 consistently in the iambic mode. I find the speed advantage of iambic to be so slight that I revert to using it as a single lever paddle with two levers! 73 ------------------------------ Date: Fri, 26 Dec 2003 10:06:55 -0500 From: Ted Albert To: "Low Power Amateur Radio Discussion" Subject: [163856] Re: Single-lever paddles Message-ID: <200312261006.55663.ted.albert@fuse.net> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Content-Disposition: inline I use the Kent single-lever paddle.

My base station has a Kent SP-1. It is solid and the dit and dah motions can be separately adjusted. This is an excellent key, but not portable. For portable work I've been using a single paddle I built according to the directions of NB6M using PC board. Cutting the PCB material is a pain, but I've come to really like the paddle much, much more than I expected. It is the paddle I used as Bumblebee 109 last July. I "enhanced" the design by adding thin plastic finger pieces, using acorn nuts for the contacts, and putting gasket material on the bottom. When sending I hold it with my left hand, and sending feels very natural to me. See http://www.norcalqrp.com/paddle/nb6m.htm for the construction instructions. I have a GHD convertable paddle that can be configured as an iambic or single paddle. Very well made and nice, but for my taste the plastic finger pieces have just a bit too much give. But that's me. My catelogs show that Bencher makes a single paddle, but I've never seen a picture of one and know nothing about them. I can get along with iambic paddles, but when I get tired or distracted my fist goes south fast with them. With a single paddle I can send much better and for longer. Good luck on your quest.

Stan, I do most of my mWatting on 20 meters, but I did check the log - 192 QSOs one 40 meters and 27 on 80 meters at 100 mWatts or less. I've run everything from 1 mWatt and up on those bands. Most are within a 500 mile radius from the home QTH - although I have gotten a few over 1,000 miles away. All QSOs are logged at the highest power for the QSO - so no lowering the power in the middle of the QSO to increase the mileage. That is just my personal policy, There are lots of guys who feel free to drop the power in the middle of the QSO to get the higher miles per watt figure. The vast majority of the QSOs are with an Elecraft K1, although I've use the K2, the OHR 500 and other rigs as well. Generally I run the K1 at 500 mWatts and cut the power with a Ten-Tec 290 step attenuator. Power out is measured with the OHR WM-2. Usually I set it up to get the 500 mWatts with the K1, but monitor it as I cut the power with the attenuator - the two seem to track very well - what the attenuator claims I should get is very close to what I get on the WM-2. 73 de Larry...........WD3P http://www.wd3p.net ------------------------------ Date: Fri, 26 Dec 2003 12:04:04 -0600 From: "Nick Kennedy" To: "'Low Power Amateur Radio Discussion'" Subject: [163861] Re: Straight key source Message-ID: <002c01c3cbda$a6512270$0400000a@wa5bdu> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit I wonder if you J-38 experts can look at mine and tell who made it.

When I put my key page together I forgot to photograph may J-37. Not nearly as nice in design as the J-38, but has a surprisingly good feel in use. (Now that I've finished the Arizona/W5JH paddle, I need to add it to the gallery as well.) My first straight key, since you're dying to know, was a huge monstrosity form the B-A (Burstein-Applebee) catalog. It was actually a code practice unit on a big bakelite base that held a 'D' cell battery on the far end and had a little buzzer for the monitor tone under a round bakelite cover near that. Just unhook the buzzer and connect up the DX-40 and you're all set to go. For SKN, I'll be using the J-38 with my HT-40 or maybe the DX-35 and VF-1.

The concept of being able to get on HF only after passing a code test will soon be discarded. Maybe now is the time to stop discouraging people to get on the air on CW unless they are proficient. Most people I know learned how to drive on the road, which is shared with other traffic. The only thing discussed here is whether to start out with a stick shift or automatic. 73, --Alex KR1ST http://www.kr1st.com ------------------------------ Date: Thu, 25 Dec 2003 00:44:24 -0500 From: Alex To: Low Power Amateur Radio Discussion Subject: [163870] Do you have the Sept 1972 issue of Hamradio?

I also use a chrome Vibroplex paddle with the jeweled movement. The jeweled movement makes a big difference. My first single lever paddle was the front of a salvaged Vibroplex bug that I sawed in half with a hacksaw. I built an electronic keyer to use with it (vacuum tubes and a mercury wetted relay). Used it for many years before going to the CMOS II keyer which I still use. I tried iambic paddles for a while but never got the hang of it. -72 and Happy Holidays- Charles W3KC ------------------------------ Date: Fri, 26 Dec 2003 13:47:37 -0600 From: "Mike Duke, K5XU" To: "qrp list" Subject: [163872] Carrier on 10.104?

I don't know if I would insist on 5 munutes error free, but at least 1 out of the five...kinda like the old CW sending tests used to be. I know some whiners will by saying that this discourages people getting on CW. Balony! (or Bologna, if you prefer). Hopefully, someone wanting to get on CW will want to sound as good as possible. If they are the sort that is happy with being sloppy in all their life's pursuits, then they will send sloppy CW, too, no matter what anyone says. Learn by doing ?? Great idea. Just like learning to drive a car by doing. When you can drive 5 miles without an accident, you're ready for a license....Dare I mention Pilot training?
