It was published in 1964 by the CQ magazine. It's title is "Surplus Conversion Handbook" and covers many of the WWII rigs including the AN/ARC-5 series of rigs. I've played with the ARC-5 rigs and they are pretty neat little rigs. The last one that was given to me was still sealed in the box. It had the original tubes and was completely mint as it was the day it left the factory. I didn't have the heart to modify it, heck, even the green felt on the tuning eye door was fresh and the mirror was still highly polished! I think that it would have fired right up on a dyna-motor! I ended up donating it to the Confederate Air Force where it now lives. These little rigs had a neat history. I may look for another beat up one that I don't feel bad "restoring" ;-) 73's Trev - KG6CYN http://www.qsl.net/kg6cyn ----- Original Message ----- From: "John Oppenheimer" To: "Low Power Amateur Radio Discussion" Sent: Sunday, January 11, 2004 1:51 PM Subject: Re: Handbook > Just received mine, along with a new Antenna (with CD) book this last > Friday from ARRL direct. > > I get a new one every five, or so, years.

I got the boards before christmas and finally took them out of their packages :) I used a turtle beach Santa Cruz audio card with a p3 1G with 1M ram "ham computer". I wish that I had more than a 6 foot high antenna. I would like to put it on 40 meters. The weather here is not very nice :( and may not be nice for a while. Now I have to think about a suitable case. The stack of boards are sitting on top of a pull out drawer/ writing arm on my desk. It is balanced by wires hanging off of both sides. So far, the receiver is really neat. I especially like the variable high and low freq filter and display of the signals. BTW I used a noiseless Zalman power supply in the pc and a variable speed fan on the cpu. The heatsink is a big honker. A seagate barracuda drive also makes for a noiseless setup. Noiseless until I started listening on 80 meters.... 73, Jim n2go ------------------------------ Date: Mon, 12 Jan 2004 01:19:57 +0100 (CET) From: "=?iso-8859-1?q?Miguel=20Angel=20D.J.?=" To: qrp-l@Lehigh.EDU Subject: [165061] For sale Message-ID: <20040112001957.12716.qmail@web20021.mail.yahoo.com> MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit Hello, I have for sale a J-37 morse key + the bracket. http://www.qsl.net/ea1rx/ventas/j37v-4.jpg I would like to swap it for any QRP stuff, or for sale. Its a very nice piece of morse history to keep. also its a good fun when you are out with your QRP transceiver and you dont have a table to put your key. You can use the bracket for other keys if you want. Im interested in a MFJ-16010 antenna tuner. Would you like to swap it??? This tunner is about 40$ so I think it would be a fair swap.

My plan is to be to the high side of 7.040 MHz by a few kilohertz, and initially listening up 1 to 2 kHz as well. When things thin out, sometime in the second hour, I'll answer stations on my calling frequency. Now that is my plan, but it could change. During last week's hunt a nasty, local noise source completely obliterated about 20 kHz of 40 meters. Unfortunately, it was centered about 7.036 MHz, and made it impossible for me to reliably copy either Fox. The noise was about 20dB over S9 in strength, with a circulating sound that would run for about a minute, and then cease for about 3 seconds. I could hear W0UFO just fine during the 3 seconds, but I would have been able to hear him the rest of the time. Just after 04:00 UTC the noise vanished. It has not reappeared since then. Should the noise reappear, I will have to move up the band 5 to 10 kHz. This is quite a bit higher in frequency than usual, but then all of you should be in the clear. Hopefully, the noise will never reappear and it will be business as usual. Thanks for your understanding. I hope to provide plenty of pelts to all you baying hounds!

Although there is probably a sufficient difference in sound quality often to make a good guess where you are, this is not always the case -- especially when the sound filtering has made the output quiet. The trick, I think, is to install an on-off switch, even one that is momentary off. When power to the board is cut, both switches reset to bypass. Then you can start counting again.

We all got very tired of my frequent requests for many, many repeats. Finally I had to ask if there was someone else who I could understand a little bit easier. I tried to be as polite as possible but I am afraid I might have hurt some feelings, and I sure didn't mean to. That was when I found out they are in India. Why India? I am sure they are the nicest people, but understanding them can be very difficult when using technical terms.

(Sorry, couldn't resist that.) On any given day there are a few hundred slide rules up for auction on ebay. The International Slide Rule Group's (ISRG) email list has a couple of dozen posts a day. http://groups.yahoo.com/group/sliderule/ The ISRG has had two circular Concise slide rules manufactured in the last couple of years in Japan. It happens that Koh-i-Noor still has a slide rule manufacturing plant in India. The group has started discussion of what might be a "dream" engineering straight slide rule to have manufactured with the best scales and features of American, German, French top line slide rules. There are several slide rule dealers online. A good one to start is Walter Shawlee's Slide Rule Universe http://www.sphere.bc.ca/test/sruniverse.html Links to others can be found there and at the ISRG page. Mert W0UFO says, "...saw them in a drawer just the other day=20 along with a circular flight calculator..." What do you have, Mert? I get first dibs. :) BTW, circular flight computer slide rules are still made in the USA and can be purchased at about any small airstrip where flying lessons=20 are taught. Run about $15. I carry and use a Pickett N600-T (6" straight),=20 Concise 300 (3" circular) and sometimes an HP-32SII calculator. The other day a dealer was calculating the area and price for a carpet we were considering. I beat him. He was fascinated. We ended up buying from him, he did a great job my xyl was very happy, and I gave him a basic 6 inch slide rule. I've worked with computers of one sort or another starting with slide rules and vacuum tube analog computers for over 40 years. I learned my integral calculus on a pair of Pace 230 analog computers.

I got ahold of some surplus weather ballons and with the help of my local welding company I was able to launch it. I use the same Stafix twine I use for my kite antenna. Its strong enough to teather the balloon and has 6 - 9 strands of stainless steel wire woven through it. http://fence-electric.com/ShopItemIG.php?item=Twine#R2W The same cautions apply to balloons as they do kites. DO NOT fly near power lines. Beware of approaching weather. Make sure you have a 1meg resistor from the antenna to ground to bleed static off. Generally for a balloon to be effective as a antenna support the weather need to be calm. If you have more than a 5 -7 mph wind the angle of the antenna will fall away from vertical and your antenna wire may wind up dragging on the ground. There are balloons specifically designed to be anntenna supports. They have an airfoil design to help them be more stable in the wind. I believe there was a article in 73 a few years back. 73 John N1OLO --- pschweit wrote: > 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 > ------------------------------ Date: Mon, 12 Jan 2004 02:34:32 -0500 From: "Kevin M., W8VOS" To: "Low Power Amateur Radio Discussion" Subject: [165082] Re: Computing (was QRP Computers) Message-ID: <000d01c3d8de$853fb4f0$66dc0a0a@magnus> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Gang, I have been following this thread with some interest.

The Red Hot only differs in that it incorporates a few mods that many NC20 owners applied, plus it has that cool red case! Anyway, the receiver in the thing is bulletproof. I found it to be far superior to my Icom 706MkII and my K-1. Two friends borrowed it before getting "real" rigs, and both commented that the receiver was far better than their new, higher end rigs. However, there is a price. Most QRP rigs use the 602, which leads to a much poorer TOIP than the passive mixer in the RH20. One reason is power. The receive current on the RH20, although nothing like a typical rice box, is far higher than most QRP rigs. The reason is that passive mixer. This is one of those design tradeoffs that you have to make. With careful attention to the front end and the various levels, the 602 doesn't have to be THAT bad. Look at the K1 -- it's pretty decent. But if you want top notch receiver performance, like the RH20, you pay a price in battery life. Dave went for receiver performance, probably because practically every other rig out there went for low current consumption. The result is one heck of a receiver. 72/73 de WB8RCR http://www.qsl.net/wb8rcr didileydadidah QRP-L #1446 Code Warriors #35 ----- Original Message ----- From: "Rich Johnson" To: "Low Power Amateur Radio Discussion" Sent: Sunday, January 11, 2004 11:56 PM Subject: Red Hot 20 > I have been studying the Red Hot NorCal 20 radio and in particular the > receiver RF and specifically from U3 the ring diode mixer to U4 the '602 > product detector and it look ingenious. > > I have considered how to improve it but considering its simplicity it may be > an optimal design.

But then when aluminum became the rage, Pickett was the brand for me. And I'm sure there were others. I think a brand named 'Post' was decent too, but I'm not sure on that. With the wood, there were all kinds of warpage and swelling issues. With metal, it was 'find machining'. Picketts put springs in each rail, and had adjustable guides. But bend a metal on and you should just toss it in the trash.

So I put it away for awhile. All this talk about 80M got me to get it out, though. I'd bought a ZM-2, built, to use with it, and I now have the hawgwahr loop I envisioned as the fitting antler for this pig. So, yesterday, I got it out, tuned it up on 80, and had the first several 80M QSOs of my life (except for a few on a QRO rig during field day, but they don't really count.) I can tell you that it's really amazing to suddenly have several more bands to play on! Now, I think I'm ready to really get it ready to play - with the dual VFO mod, more keyer memory buttons, speed and RF pots, and a mod to increase the bandwidth linearity.

Of all the mods I have in #16, (and I think I have them all), the RF Gain mod is the most used. It REALLY helps, particularly on 40M, where signals are pretty strong.

Having won a Small Wonder Labs PSK-20 QRP PSK-31 transceiver in last year's FP QRP Club Worked All Pigs contest, I'm working on making this thing frequency agile. Once I get it going, I'll post the mods, as this little rig will work ALL of the digital modes that a sound card can generate and decode. I have it running on the original crystal controlled frequency of 14.070 +- Digipan's audio. I did have the DDS sig-gen hooked up to it, as an early experiment, and even with the low injection voltage to the SA602 and TUF-1 mixers, the receiver and transmitter worked, though with low receive sensitivity and lower power out. I successfully made PSK-31 and RTTY QSO's with it this way, but signals had to be really strong to hear them. With the 5.068 MHz crystal oscillator providing the frequency control, it's really a pretty good little QRP rig. Since Dave Benson of SWL used cheap 9.0 MHz computer crystals for the filters and for the BFO for the filters, it is set up for LSB which makes it ideal for RTTY since the convention is for LSB on RTTY anyway. It will generate SSB Voice but LSB only unless you make provisions to change the BFO frequency to 9.00 + whatever it takes to match where the filter crystals match out at. I May try that at a later date. Since it uses the 9.0 MHz IF, and 5 MHz conversion oscillator, there's no reason one couldn't set it up for USB operation on 20 meters, and rig it to switch filtering and P/A coils to operate on 75/80 meters. Especially with the DDS signal generator as a VFO for the thing. The other thing that comes to mind, once I get the DDS integrated is re-working the 5 MHz oscillator with a 9 MHz crystal for opposite sideband. That way it could be easily switchable. All sorts of interesting possibilities. Being out of work and broke, I've got lots of time to think up things to do with this thing.

For those close to Toronto or wanting mailing I have a Ten-Tec Century 21, T-T Corsair II, to begin with the larger shack pieces that should go. For those who are handy there is a T-T qrp amp model 405 with p.s. that probably needs new drivers (hopefully not finals, but that is yet to be determined) - we can talk about that if there interest. T-T Argonaut 509 with external CW filter and the digital display. That's what I can think of for now.

Well, I was in the shack on Saturday, and made the calls. The band was dead, dead, dead -- if the antenna tuner didn't indicate low SWR, I would have started suspecting that we didn't have an antenna connected! In any case, we will be trying again today, at 2345 UTC. In addition, we've decided to do this from the shack, so we've got access to our full complement of antennas. If 10 doesn't pan out, I'm tempted to drop down to 40. Any suggestions for frequency? Thanks to everyone who (tried) to participate.

To do this, remove the 5 Mhz xtal and C49/C50, then apply your DDS signal to the base of Q5. Basiclly, you need more drive current, not more amplitude. Also, to get USB, you just have to use high side injection rather than low side. So, use 23 MHz when you want USB and 5 MHz for LSB. Easy to do with the DDS VFO! That's a whole lot better then messing with the BFO. (You might have to jumper out L7 and remove C51 when you go to 23 Mhz LO) 72, Steve, KD1JV "Melt Solder" White Mountains of New Hampshire http://www.qsl.net/kd1jv/ ------------------------------ Date: Mon, 12 Jan 2004 11:22:16 -0500 From: Steven Weber To: qrp-l@lehigh.edu Subject: [165114] Slide rules Message-ID: <3.0.6.32.20040112112216.007c5e30@mailhost.ncia.net> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" I still have the set of Picket S/R's (12" and 6") they made me buy when I started collage.

All great magazines, and all dedicated to teaching you more about the workings of your computer and giving you a variety of games, both simple and semi-complex. Those were the days of computing, when computers were computers. Now computers are used as entertainment devices. It takes no knowledge of what resides behind the screen to play recent games. Even the game scenario is simple, it's the animation that is interesting. And yes, there wee magazines devoted to special purpose machines, like "Micro 64". They were a little more than simple listings because they also included how to build it articles. British magazines were also there. I used to read "Popular Computing (British)" when I was assigned to Europe. I still have a Commodore clone I bought over there and a Sinclair mini machine that was quite a bit of fun and a real challenge to pack code in. I think where UK computing went astray was the emphasis on the BBC machine. I think if I were going to teach 8 bit computing today I might look for some of the old magazines and books from that era. 8, and 4 bit computing have application today with the PIC revolution. Incidentally, did any of you ever win one of the monthly programming contests that Wayne ran in "Micro 80"?

Apparently these which were part of CIE's electronics course, and they are quite common. There are probably many still available in the as new condition I got mine in, as they usually saw little actual use after the student had finished the course. At least this is what the collectors seem to say about these. While they do NOT have the a scale for db as the Lafayette rule you mention above, it has alot of specialty scales for electronics on the front, and two decimal point "locator" nomographs for reactance and resonance along with formula charts on the back.

Mike has already warned you about bent aluminum. That is the kiss of death for a Pickett. K&E and Post were made of bamboo. Slide riles were made, mostly, by drafting equipment companies. The bamboo they used was especially stable. In this area, Washington, DC, we have an annual "Machine Tools" Show where many vendors sell new and used slide rules. I bought a new pocket model Pickett there several years ago. I had never owned either a Pickett or a pocket model before. My favorite is the K&E. I still have the one I bought new at the K&E store here in Washington! Served me well! The reason I say to be sure it has the original book with it is almost anyone can puzzle out the basic scales, but the book will be of great help when trying to figure out the rest of the scales! 7 ------------------------------ Date: Mon, 12 Jan 2004 11:42:53 -0600 From: "Michael Melland, W9WIS" To: kd1jv@moose.ncia.net, Low Power Amateur Radio Discussion Subject: [165127] Re: Slide rules Message-ID: <000e01c3d933$83434810$4986e98d@winad.it.uwosh.edu> MIME-version: 1.0 Content-type: text/plain; charset=iso-8859-1 Content-transfer-encoding: 7bit I remember learning to use a slide rule as well.... and my first calculator.

To my knowledge, no ITU member administration will license a VFO-controlled transmitter for radio services requiring crystal control.

And I have bought several older handbooks too. I am particularly proud of a 1940 handbook that os from my birth year. I like to look at the projects, but I really enjoy the ads they used to run. They were like the Sears and Roebuck "dream" books to me, except they were ham dear! I agree with Ed, look at the new ads and see what has been updated before you invest. The book includes lots of new projects especially written for the issue. I am a sort of radio historian. I have lots of "handbooks" published by various sources. I have the complete Ham Radio set of Handbooks. I have both QST and Ham Radio on CDs as well as most issues in printed form. I have several issues of the CQ Surplus Conversion Handbook, along with several other surplus handbooks. Back when I got started in ham radio surplus was everywhere. Hams were converting surplus radios for daily use everywhere. There were sort of the transistor radios of the day! Watch ebay for various books and magazines of all types.

There's a certain amount of that spirit in the Linux groups although the hardware is still neglected somewhat. Articles in those magazines got me started programming microcontrollers.

I still have it here, along with its somewhat browned and tattered original manual, but I haven't used this critter in years. It's a K&E.

We'd concoct math problems, and then race to the answer. Lots of fun---especially to me as a kid who abhorred math! These days I use a TI-36X "solar" light-powered calculator ($12) that lets me do things such as polar to rectangular and rectangular to polar conversions (to solve phased antenna problems), convert hex to decimal to octal (!) and back, or handle engineering units (very useful for everyday electronics calcs), etc. Man, how times have ch
