Fig. 4. Differences in pi ft numbering between LM74J and LM1458 (dual 741), Note that the schematics shown in Fig. 1 and Fig. 2 are labeled with pin numbers for the 741 and will need to be relabeled if the LM1458 is substituted. 84 73 \mateur Radio Today « December 1997

Looking at the circuit shown in Fig, 2. you'll sec a coupic of small modifications that I made to mine. 1 used ten easily obtained 10 ft. 1/4 W carbon film resistors in parallel for the 1 ii resistor designated as R5 in the schematic. I also used a series/ parallel configuration (of four 100 fl 1/2 W resistors) for the 100 fi, 2 W resistor shown in the schematic as resistor R4. Placing all of the resistors right on the board, and v\ iring them as in Fig, 2. takes up very little additional room. 1 also changed R9 to 100 Q and added a 500 Q volume control (R6) to the speaker circuit. This affords some control over the ultimate \olume level of the unit's output, i found that returning the speaker circuit directly to the common point increased the obtainable volume level a bit, especially if you're planning on using nine-volt batteries in place of the recommended plus and minus 12 volts as in Jim's original design, Again, however, it's probably best to build the circuit up originalK by following the schematic of Fig. 1 exactly, then you can begin to experiment from there. I used a socket for the 741 TCs for ease in changing the op amps if needed, and 1 employed a ven small "flat'' speaker (snapped up at a recent ham I est) for the sound output device. 1 built mv own short de-

And that brings us down to the public (wrhich may well include you), which shells out to buy the tabloids. This is the same curiosity that slows traffic as it goes past an accident. It's called gawking. And it s the same interest that increasingly dominates our PV news coverage. It even has a lot to do with the popularity of talk show s and Geraida! interviews with weirdos. If you waste your time watching or reading this kind of crap, then you. in a way* helped contribute to Di's demise.

If, as is becoming increasingly believed by those studying death, we take our lifetime of memories with us when we pass on to whatever the next plane is. then many people are going to have a lifetime of irrelevant gawking in their memory storage, white 111 have the contents of several thousand books and conversations with experts in many scientific fields to work with ''over there." As ye sow, so shall ye reap, it says in the Bible/So what are you sowing? Repent!

No, I have not yet succumbed to millennial fever, so 1 view with interest and amusement the many prophecies for an imminent end of the world—on at ihe least, a major catastrophe which will " w ipe out 90% of the world's population." So there^s still time to clean up your act and start inputting stuff that will not onl\ help you during this incarnation, but might give you an edge in the long term. When you consider the general level of laziness, it's pathetically easy to get to be an expert in almost any new field that you find interesting.


Tliis photo of Patrick Curran KB2TNY {Photo C) reminded me of the first time I heard about amateur radio. I was 12 when my grandfather took mc to visit a friend of his at a hotel in Bethlehem. New Hampshire. Bethlehem was a summer vacation town with 30 hotels (some huge!) and over 100 rooming houses. The son of the pastry cook (Mamie Stevenson) had a ham Station in a little building out in back of the hotel. Harry W1CUN was sitting there talking to someone on 160 meters, the tubes in his final glowing cherry red. Wow! That got me to listening to 20 meters using my other grandfather's all-wave radio and collecting QSL cards from hams all around the world. How could I, even in my wildest dreams, imagine that 12 years later I'd have my own ham station in that same building, with me talking to the world?

That was right after World War II. w hen I got discharged from the Navy and had the summer of 1946 off before going back to college in the fall. Since our farm had no and test equipment. Get your own copy by calling {800} 877-0072 or FAXing (800) 813-0087. It's well worth having in your catalog library, and if you're in Fort Worth or Denver, you can check out the ech America walk-in stores!

The very best of Season's Greetings to everyone. Sue (KA9UCK) and I hope that your stocking is filled with all of the toys that a ham could want! Well, almost all—there's always next year! We'll return wilh tSic electricity and Harry had moved to Vermont, 1 got to use his old shack for the summer. I put up antennas all over the place, complete w ith a vee beam for 75 meters.

Pat was eight years old when This photo was taken and he was husv racking up grid squares on two-meter SSB. Which brings up the matter of your kids (and probably grandkids). Are you sneakily infecting their dirty little minds with the ham radio virus? Hey, anything to keep them from getting being run over on the information highway. Or have they got their ow n Web site already?

If you've already done your dirty deed, piease sit your kid down at the rig for a photo. Help convince me that amateur radio has not degenerated totally into a hobby for middle-class elderly white men—just a way for them to mark time through those few "golden" years between retirement and their e\eiuual incarceration in nursing homes.


Luck, a.k.a. serendipity, had me reading about a book by Dr, Harold Burr in the World Research News newsletter which seems righi down your alley. That is, of course, if you have any pioneering blood left in your veins. The book. Blueprint for Immortality, was published. I believe, about 50

years ago.

Burr uas messing around with a very sensitive voltme ter and found that all living things have electrodynamic fields which can be measured and mapped with a millivoltmeter. He called these "fields of lifer or L-fields.

He found that he was able to detect when just about any part of the body wasn't working right, such as discovering cancers way before any clinical signs were detectable, just by the changes in voltage. This also turned out to be an extremely accurate w ay for uomen to determine the moment of ovulation.

The crummy article didn't say where Burr measured the voltages, just that the system worked on plants, animals and humans. I'll see if I can get a copy of the book, or at least more information about this. Maybe you can find a copy for me? In the meanwhile, lei's see some articles on building mill ¡voltmeters, and maybe some data on what you find using em. If you have any doctor friends, tins could be an interesting and potentially \ aluable research projecL iil be surprised ii there isn't some connection between acupuncture points and significant voltage measurements.

Then, once we have some maps of the body's voltage fields, I wonder if there could be a reciprocal situation, where the application of a might stop a developing illness? 11 mm. you might want to check with an oscilloscope, just to make sure we're dealing with DC voltages.

If you stop to think about column more in its normal format next time, but between now and then, try putting together Jim Wood's "Beeper" and give it a try I think you'll like it.

Please be sure to send me any ideas that you wouid like to see included in this column.

this, the Bioelectrifier™ and the pulse unit, we're getting more and more into medical electronics. Well. that area is far less explored than potential consumer electronic products such as digital video disks. The communications and consumer electronics fields have pretty much left us amateurs behind. bur that doesn't mean we can't find areas to research which are being ignored by both industry and government for economic or political reasons.

You might want to check ihe books by Robert Becker on electricity and the body. They're in my hook guide and I've reviewed 'em in my past editorials. And while you're at it, you really ought in check on Rawle's and Davis's work with magnets and the body. And Ott's and Liebermans with light and sickness. All these areas of investigation are pathetically under-researched. Why ? Because modern medical research is almost totally devoted to finding patentable drugs lo alleviate sy mptoms, Thai's wrhere the big money is, not in either curing people of illnesses or helping them stay healthy. And money runs the medical business, just as it does everything else*

Good tuck or finding a doctor interested in working with you on L-field>, the Bioelectrifier, or the pulse unit. Let me know how you make out.


When you get sick or break something, you go to the doctor So do I, That's what my folks taught me and what I learned from school the radio, movies, newspapers, and magazines. But as I've been reading. I've been getting a different perspective on the role doctors should play.

Now iiiar 1 understand that virtually all of our illnesses are the result of what we've been doing to our bodies— lifestyle diseases—I can also understand why doctors are not taught much about health and nutrition in medical school. Can you even imagine someone going to a doctor and explaining that they are in excellent health, they just want to know what they should do to stay that way? You can bet lhat none of the medical insurance plans are going to pay for that office visit. You can also be pretty sure that your doctor isn't going to have a good answer.

If you've been to college you know that about 95% of what you "learned" is now long lost, 3t went into your shon-term memory so you could pass your tests. Well, it's no different for doctors in medical school. Like us, they learn better by doing, and that's during their internship, where they learn to diagnose symptoms and fix broken bones.

Doctors get almost all of their information about drugs from the drug sales reps, along with paid vacations, which include a seminar on the company's latest drug. They also bribe doctors with frequent flyer miles and "research grants" to use their drugs. This starts earl), with the medical student being given a stethoscope or black bag, and then later business cards and prescription pads. What the drug companies downplay are the side effects of their often toxic drugs.

Let me quote the president of the AMA: "Medical education has traditional!) focused on the principles of acute episodic heafth-care delivery, overlooking the concepts and applications of nutrition and preventive medicine,"

As I've probably mentioned too often, the in ore research I've done on this, the more convinced 1 am that virtually every illness we get is lifestyle generated. That s something to think about when you, someone in y our family, or a friend, has a heart attack, stroke, cancer, or any of the chronic illnesses such as arthritis and diabetes. Oh yes, Parkinson\ and Alzheimer's too. Our hospital beds and nursing homes are filled with people who have mistreated their bodies,

But can 1, just using reason and endless scientific studies as a took get you to give up beer and pretzels? Hamburgers and fries? Frosted fruit loops for breakfast? Toaster tarts? Doughnuts and coffee? Potato and taco chips? Deep-fried onion rings? Yummmm. Hey, I like most of that crap too. On my birthday weekend Sherry, Sage (daughter) and I went to the county fair and had a fantastic time eating the most delicious onion rings in the world, a great Italian sausage sandwich (cut into three), Pennsylvania Dutch funnel cake, and other such death-defying foods. Well, we took it easy this year In the past we aho ate a bunch of fudge, barbecued chicken, ears of corn, do-it-yourself sundaes, and French fries.

But most of the time these enlightened days I eat three apples, a couple bananas, a couple ears of fresh com (in season), a salad, a bunch of raw vegetables, and a curried chicken thigh. And I love it,


If you an? still buying the governments line that UFOs bunk, ihen you sure haven't bothered 10 read very much. One of the best books I've found so far about the aliens (ETs, Visitors) is the recently released The Day After Roswell, by Col, Philip Corso (Ret,). Corso was right in the middle ot things and has about as good credentials as you could ask for. He headed up the Foreign Technology desk in Army Research and Development at the Pentagon, worked for four years on the National Security Council, and so onT

In his book Corso describes the aliens recovered from the crashed ship at Roswell, as well as many of the artifacts he used to help industry R&D groups de-veiop advanced technologies.

The ship, by the way, had no facilities for eating or waste disposal, so it was more like a scout ship and obvious ly had to operate from a base or mother ship.

The rash of recent TV shows with interviews of people who were there at Roswell 50 years ago. plus interviews with the children of those who w ere there, have all had the same consistent story. Something big and important crashed there and the Army went to a tot of trouble to try and cover it up, including scaring the wils out of the locals with threats as to what would happen to them and their families if they ever told what they'd seen.

Yes, aliens are here and have been here for well over 50 years. Yes, their technology is waj the iieek ahead of ours. Their ship had no controls or instruments, being operated by mind control via headbands worn by the ETs.

Obviously, if they meant us harm, ihey could have quickly wiped out our resistance,

With that in mind, the reports of contactees make a lot of sense, whether The Skeptical Inquirer likes it or not, In this case The National Enquirer is more in line with reality than Skep. Hmm, I wonder how long it's going to take for Skep to acknowledge the reality of cold fusion. They've been ridiculing it for years now. And rhat helped me lose all respect for the magazine,

The Corso book is ISBN 0-67!-00461-L runs 341 pages, and costs $24,

The next time you hear an Army or Air Force spokesman talking about the wreckage at Roswell being a weather balloon and the ETs merely dummies (which were not used in tests until six years

•w after Roswell, by the way), you'll be laughing along with me. Oh yes, Time dutifully followed the Pentagon line in a recent cover article. So much for truth in our media and from our government.

Corso explained how he helped several new technologies develop—such as fiber optics, l ight vision, integrated circuits, and lasers—by cautiously feeding the alien technology to our scientists.

Why did Corso wait this long to spill the i^ans? He explains that he'd promised his general that he VI keep quiet while the general was still

Oh. how the DX rolls; in when the solar flux improves! As I write (mid-September), solar flux has jumped from the sluggish 70s of the past two years to a sprightly 108, representing a 50^7 increase, and the DX bands have reacted accordingly. This is a good sign and may represent the hoped-for effective beginning of Suns pot Cycle 23.

The calendar shows the worst days for propagation this month (P-VP): lst-3rd, 1 lth-13ih, and 31st. The best days (G) should be the 19th, 20th, and the 27th. Average days (F) are likely to he the 5tb-9th, 15th, 22nd-25th, and the 2^th. The remaining days should shou conditions trending. Don't let those Fair and trending days dampen your enthusiasm, though, because much good DXhas been worked under such conditions. Rejoice! Things seem to be looking up.

10-12 meters

Generally Poor, except for occasional transequatorial propagation with F2 openings on the best days—most likely South and Central America.

15-17 meters

DX to Africa and Latin America on the Good days possible, with short-skip out to about 1*000 miles or so in the US.

20 meters

Your best band for DX openings around the world from dawn to dark, and openings to the Southern Hemisphere after dark in evening hours. You can expect excellent short-skip during the daytime to 2,500 miles or so.

30-40 meters

These bands ought to be open for DX from just before sunset to just after sunrise. Signals from the east should peak until midnight, and after midnight to other areas. Daylight short-skip of about 500 miies w ill be possible, and nighttime shon-skip to L500 miles or more will be available.

80 meters

Occasional i)X to various areas of the world should be possible between sunset and sunrise when QRS levels permit on alive. NTow. with the general gone. Corso has put the whole story in a book—and it s on the best seller list!

A Roaming ROM

If you drive around the country a lot voull want to look inro the new ARRL Repeater ROM. This S44 ROM has maps of the US and Canada and it will lay out a travel route for you showing the repeaters you can access along the way. The ARRL Repeater Director} is handier in the car, but if you are planning a long trip the ROM will lay out the details for you so you can kerchunk repeaters as you go. I hope you have better luck than 1 do in finding anyone alive to talk with. When 1 get into a town w ith ten repeaters 1 figure I'm lucky to find even one where anyone is listening. With over 600.000 licensed amateurs, and over iialf pretty much isolated up on two meters, how come I can t find any life on all diose two-meter repeaters?

The ROM only works with PCs. so we Mac people can go fly a kite. Yes, 1 have a PC. but I hate the damned thing*
