What makes sense to me, and it requires discipline on my part, is to remember to turn the virus softare back on after I've had to turn it off because it interferes with some legit operation. There are times when I cheat....turn it off when I'm off line, do my stuff that doesn't work with a virus checker, and then reboot, since the virus stuff is in startup.

We are looking across a gulf of two, or possibly three, generations at a group of kids who grew up living and breathing technology which did not even exist when we were growing up. We stand before kids who can write applications on their PC's, youngsters who have pointed out to NASA that "virtual" space travel as exemplified by the Mars Rovers may be an acceptable alternative to manned spaceflight. These young folk are totally comfortable with the Martian images they see on the Web and on TV, images which ignite their imagination and vision.

K0PC was burried in S9++ SSB and digital QRM, before he faded into oblivion. Never did find/hear K0UU. Both just too close for band conditions here tonight. Hear plenty of 2s, 4s, and 5s in the pack. Right now it's -27F air temp, with a wind chill of about -60F. Supposed to get down to -35 to -40F air temp by morning. Had the boiler go out earlier tonight, but managed to get it re-lit. Have the Y2K heater fueled up and ready to go, just in case. Going to be a *cold*, foxless night in ND tonight. :-( 72/73, Todd, AG0T ------------------------------ Date: Tue, 27 Jan 2004 19:50:30 -0700 (MST) From: Karl Larsen To: qrp-l@lehigh.edu Subject: [166413] FOX: Three fer!

I believe the Jensens and the TDKs are rated 6-8dB below the Koss but in practice are about the same sensitivity. (yes, I have a pair of the Koss "plugs" and have put them on my recommended list below the ones I mentioned because they are typically more expensive). There seems to be a sensitivity ratings race going on akin to the old stereo hi-fi watts race of a few years back. If you want ruggedness at only a slight sensitivity penalty buy the Sennheiser BP-100. They are of much better construction than the Koss and guaranteed for two years.

It's an addressable criticism that has given DC receivers an undeserved bad reputation. If you have a VFO controlled transmitter and a VFO controlled DC receiver what would you do to answer a CQ? You'd zero beat the CQer (note: true zero beat as in zero Hz note/absence of signal) with your receiver. You'd flip on the transmitter spot switch and then adjust the transmitter frequency for true zero beat in the receiver. Then you'd turn off the transmitter spot switch and jog the receiver dial a little left or a little right to get a pleasant CW note from the CQer. Then you'd answer the CQ. And you would be calling right on frequency. This is a simple, deterministic procedure you could teach anyone. And you'd probably find more hams calling on frequency than by trying to adjust the VFO on their superhet transceiver for an exact 700 Hz CW note. I know, I'm one of them. Crystal control often makes it impossible to get the transmitter on the CQers frequency. And that fact will be true whether you are using a DC receiver or a superhet. The difference is that the DC receiver operator will sometimes hear and call a phantom CQer too far from the transmit frequency. In that same situation the superhet operator won't hear the CQ at all since he/she is listening near the crystal controlled transmit frequency and the opposite sideband suppression will eliminate the CQers signal. The end result in both cases is the same - no QSO. Yes, it can be frustrating to call a CQer that can't hear you. Agreed. But don't fault the DC receiver, fault the lack of a VFO on the transmitter for the fact that a QSO didn't take place. IMO, it's time for the QRP community to figure out (again?) how to build inexpensive QRP radios with VFOs/PTOs. And isn't that what AMQRP is doing?

The impedance at the end of the wire where you are feeding it at that frequency is very high, probably on the order of 2000+ ohms resistive and probably some reactance too. Your tuner may still tune it but you'll have to do it manually. If that doesn't work I'd attach a small 3 - 6 foot wire on the tuner's ground terminal and try manual tuning again. And if that didn't work I'd attach a 1/4 wave "counterpoise" (66' wire - lay it on the ground) off the tuner's ground terminal and try again. Note the 66' wire might make 40/20 meter tuning tough. A center fed wire of the same length would probably be easier for your tuner but I understand it's not always possible to hang a transmission line where we might want it. :) GL es 72/73, *Lew* N5ZE ------------------------------ Date: Wed, 28 Jan 2004 09:16:19 -0500 From: Bruce Muscolino To: sergio@village-buzz.com Cc: Low Power Amateur Radio Discussion Subject: [166449] Re: longwire and 80m..

First off, you shouldn't have to run all your gear on battery power. To me, this means you either have a "ground loop" somewhere or you have done a poor job of bonding everything together. No you don't have to weld the units together, but you should have the cases and/or chassis securely connected together. With the HW-8 you can probably get away with hook up wire; with the TS-520 you should be using heavy gauge wire or braid. Antenna length. A 130 foot wire is awfully close to a half-wave at 80 meters. It will present a VERY high impedance to your tuner. You may have actually exceeded your tuner's range. Also, you are using much higher power now and that could be showing you where you have a problem. Hogs power is much less tolerant of loose or poor connections. What kind of SWR bridge are you using? Does it have actual scale units on it AND a power range low enough fo the HW-8" Are you using the same meter on a higher scale with the TS-520? This way is the only way to accurately compare SWR readings between two rigs. Are you running a tuned ground? I know everybody says you don't need a ground with a half-wave, but I have found it helps. The lack of a ground may actually be masking other problems such as poor connections. Check out your entire station. Look at how you are interconnecting the units. Install a tuned ground for your antenna and a safety ground for your station. If you must use two different SWR bridges for your stations, optimize the TS-520 installation first. It is easy to go from 100 watts to 2 watts, but not the other way.

Published experience shows that a good antenna installation will probably allow up to 50 kHz excursions before the SWORE rises to 2:1. Your experience may vary, of course. Carefully watching your SWR as you move up and down around your tuning point. You should NOT use carrier level to adjust power output. You use the ALC control while watching the power output meter reading. Tune up at 100 watts first before lowering power.

The kids are stimulated with a barrage of images from TV, videos, and games, but these are not necessarily good stimuli. Young people read less, exercise less and DO less than the previous generations. Incidently, reading and listening for that matter cause more brain activity than watching. Yes the kids are inundated with tecnology but mostly their involvement is pretty much passive. I work in an engineering lab that often employs students and graduates. I find it amazing how a young person can come to work with a degree in engineering or computer science and know virtually nothing practical about the tools of his trade. Mechanical engineers are not very familiar with machine tools and have great difficulty designing parts that can be fabricated. Electronic engineers don't know how to solder and have minimal parts recognition skills (and that's just the beginning). Computer science grads think anything can be simulated and that prototyping is unnecessary. Are these kids smart (intelligent)? Usually. Are they educated? Hardly. Have they wasted most of their young lives on trivial stimulation. Definitely. Believe it or not there is a crying need for people willing to help kids learn to use their brains by building stuff--that includes simple radios or kites or telescopes or doll houses, etc. Is their competition for their attention? Yes, way too much. Most of the challenge involves getting their short attention spans directed to something positive and helping them learn to apply themselves to constructive, hands-on pursuits. It is a challenge to get their attention and help them, but it is also one of the most rewarding things you will ever do. If we want to compete in world markets in the future we have to do something now--like start looking around your own familly or neighborhood for an opportunity to help a young person develop REAL and useful technical skills. Having said all this, I admit. There are exceptions, but they are exceptions--not the rule. I say turn off your radios for a while, buy a kit, and help some youngster in a way that will do him permanent good. Bruce kk7zz P.S.

Yes, just adjust the carrier control down until you're at 5 watts or whatever you like. The unit I had adjusted very smoothly down to essentially zero, and it held pretty well. For QRP I left the loading at minimum (max CCW) and just dipped the final and tweaked the carrier control to get 5 watts. The exciter tuning control (forget what its labeled) does have to be peaked as you tune the band or the power drops off. If you run an antenna tuner, same there. 30 years later, the TS520 is still a very nice rig! 72's, Phil WB7AEI ------------------------------ Date: Wed, 28 Jan 2004 09:34:37 -0500 (EST) From: ham@w3eax.umd.edu To: sergio Cc: Low Power Amateur Radio Discussion Subject: [166455] Re: ts-520 and qrp..

If the surrounding RF signals are large enough to create a problem in the receiver, a larger attenuation value is needed. If I could have two different attenuators that I could separately kick in, I would be tempted to go with a 10 db and a 20 db attenuator. The values for a 10 or 20 db pi type attenuator can be found in the ARRL handbook. If I had only one, I might be temped to go with a 15 db attenuator. For a 20 db pi type attenuator, the "leg" values are 55 ohms, the center series value is 495 ohms. For receiver front end purposes, these do not need to be precise, so 47 or 51 ohm along with a 470 ohm resistor is good enough. For a 10 db pi type attenuator, the "leg" values are 65.8 ohms, the center series value is 142.3 ohms. 68 ohm and 150 ohm resistors are probably good enough. If you want the attenuation to be more precise, you can either order 1% resistors from Mouser or Digikey, or you can parallel higher value resistor with lower value resistors to get closer to the right value. For example, a 55 ohm resistor could be formed by using a 68 ohm resistor in parallel with a 270 ohm resistor. Given the 5% tolerance of most common resistors, you could get dead on if you measured and sorted resistors. - Dan, N7VE ------------------------------ Date: Wed, 28 Jan 2004 07:09:10 -0800 From: "PHILIP DECAIRE" To: Subject: [166457] Re: longwire and 80m..

As such it presents a high impedance (about 5000 ohms) to your tuner. MOST tuners won't handle that, although there are designs that will. The NJQRP web site has some good EFHWA (End Fed Half Wave Antenna) info. Simple tuners can be built that will tune it on 80M. The advantage of the end fed half wave is that you don't need a good "RF ground". Usually a relatively small counterpoise (like a dozen feet of wire layed out on the floor) will work. That's because the input current to the antenna is so low, due to the high impedance. The wire will also be close to a multiple of 1/2 wave on all the other bands, and so you may have difficulty tuning it on them too with a standard tuner. 72's, Phil WB7AEI ------------------------------ Date: Wed, 28 Jan 2004 09:14:45 -0600 From: "Jim Sheldon" To: "Flying Pigs Mailing List" , "Four States QRP Group" <4sqrp@mailman.qth.net>, Subject: [166458] FS/FT MFJ-9040 40 meter QRP rig Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit For Sale ($60) or trade (make me an offer).

There are a few exceptions like Code Red, but these tend to only be issues if you are running a web server or something like that on your PC. The firewall prevents someone from connecting to your computer who shouldn't. It can also prevent you from connecting to things that maybe you don't want to. But most viruses come in on your email, so the firewall won't do anything to stop them unless you block email. One thing it can do, though. Some viruses provide a port for someone to control your computer. If you have been infected, the firewall can prevent them from taking control. But most viruses do their damage locally so the firewall has no effect. There are firewalls that examine email for viruses, but they are pretty much not for consumer use. And they are, of necessity, not as good as your normal antivirus software. So, your not being attacked since you installed the firewall could be attributed to sheer dumb luck. More likely it's a result of you being a little more sensitive to keeping your antivirus software up to date and being judicious about what you click on. It's not rocket surgery to keep clean from viruses, but unfortunately there is no magic wall we can hide behind. The only answer is eternal vigilance. 72/73 de WB8RCR http://www.qsl.net/wb8rcr didileydadidah QRP-L #1446 Code Warriors #35 ----- Original Message ----- From: "ERNEST GREGOIRE" To: "Low Power Amateur Radio Discussion" Sent: Wednesday, January 28, 2004 7:52 AM Subject: Hardware Fire Wall Best Virus Protection > Hello Gang, > > My computer was attacked with a virus even though I had PC-Cillin and > Zone Alarm for a fire wall a while back. > > I had to start over and wipe the hard disk clean and re-install > everything. > > The computer guru at a local shop suggested a router for a hardware fire > wall to stop unauthorized access.

You are correct. Mostly they prevent Bad People(tm) from outside from finding a way into your computer. Also, many of the virus/worm emails and web pages and popups install a "back door", allowing aforementioned Bad People(tm) unfettered access to your computer, which they will then typically use to spread SPAM and more virii throughout the world. Many also install keystroke loggers which capture things like user account names, passwords, credit card numbers and such things and give them to the originator of the virus/worm, who you probably do not want to have such information. The best defense for an Internet-connected PC is a real firewall running on a secured host between you and the Internet. This firewall should control access from both directions, proxy web connections, filter and de-SPAM email, log and notify you of hack attempts, and generally permit only what you wish to permit. Even with this, if you use Windows you are at the mercy of the latest Internet Exploder or Outlook security hole - but the risks are far less severe, to the point where your installed AVG or Norton or whatever desktop anti-virus can be more effective. Using something like Pine or Mozilla to read your email on a non-Windows system adds a far greater amount of safety. Unfortunately, most people do not have the skills and experience needed to build, install and maintain such a firewall. The little hardware firewall boxes are certainly better than nothing, but don't be lulled into thinking you can get rid of your AV software and not pay attention to your email security. ObQRP: I suffer from a LOT of QRN at my location. The antenna is wire in the attic, and unless the local power company has blessed me with the opportunlty to run off battery power, it's REALLY noisy, especially at night.

I'm looking more at something like a NIR-10, and older Timewave or MFJ or something I can pick up for under $100. I have also seen the ANC-4, which is a different animal altogether.

Having just completed one of the Arizona ScQRPion paddles, I "borrowed" an idea from them that appears to have cured the problem: Remove the two arms from the base and drill a small hole in front of each of the bearing threaded holes, being careful to leave clearance for the original flat washers. Next, lightly sand the underside of each arm in the area just forward of the bearings. Take two strands from a piece of stranded hookup wire and carefully solder a piece to each arm. The tricks here are to align the points where they are soldered to the new holes in the base, and to keep the build-up of solder to a minimum so clearance is maintained. Next, remount the arms with the new wires extending through the holes in the base. Finally solder the two wires to the ground lug located in the approximate center of the base. After completing the mod, I had a chat with K0ZK on 14060 and the paddle performed flawlessly. -- 73, Bob Patten, N4BP Plantation, FL E-Mail: n4bp@arrl.net Website: http://www.qsl.net/n4bp QRP ARCI #3412 SOC #1 ARS #799 Whiners #6 FISTS #7871 ------------------------------ Date: Wed, 28 Jan 2004 11:26:49 -0500 From: "John" To: "QRP-L" Subject: [166465] FS: 2 meter handheld Message-ID: <001d01c3e5bb$8c127210$db3a8d41@ATHOME> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Alinco model DJ-F1 2 meter handheld.

I have heard a lot about making it "too easy" with some of the kits, but I really have to disagree. There are plenty of kits with a moderate to high degre of difficulty out there. For example, I have built three Rock-Mites now... to me they are almost trivially simple to build, but I've been building stuff a long time. It would be tough for a lot of folks. Heck, my own keyer kits take an average builder about as long as it takes your coffee to cool off, but then we're not ALL average builders!

Sure, some people do that for fun, but they certainly didn't start out that way.

Actually, that's not true. You CAN throw lots of things from aircraft as long as they land in places where they can't do any damage. For example, many flying clubs like to practice flour bombing runs down the runway. Toss a sack of flour out of the airplane and it makes a nice little puff when it lands. Whoever gets the closest to the target wins. =20 It's also not uncommon for bush pilots to toss a few darts at the tundra to evaluate how soft the surface of the tundra is. =20 And finally, let's not forget those unruly passengers wearing parachutes.

I have one pair still in the package. The specs are: Power Handling: 50 mW Impedance: 16 Ohms at 1 KHz Sensitivity: 108 dB/mW Frequency Response: 12-22,000 Hz These are my favorite ear buds by far and work very well with the K1, DSW-40, and SW-40+. Best feature of all is the price! They cost only $8.99!! I'm sure that you could also find them online with a google search. Saying all this, I haven't tried the Koss type, but these fit my ear very well and sound fantastic for CW. On the K1 I typically run the volume pot to the 9:00 position max, and usually lower. I have tried other brands, but they either didn't have the nice sound or were uncomfortable in my ear, and to me that's the most important thing when you'll be wearing them for an extended time. 73's Trev - KG6CYN http://www.qsl.net/kg6cyn ------------------------------ Date: Wed, 28 Jan 2004 10:02:28 -0700 From: "M.M."

The best protection against virii (viruses?)

Sergio - The TS520 makes a great QRP rig. Yes, just adjust the carrier control down until you're at 5 watts or whatever you like. The unit I had adjusted very smoothly down to essentially zero, and it held pretty well. For QRP I left the loading at minimum (max CCW) and just dipped the final and tweaked the carrier control to get 5 watts. The exciter tuning control (forget what its labeled) does have to be peaked as you tune the band or the power drops off. If you run an antenna tuner, same there. 30 years later, the TS520 is still a very nice rig! 72's, Phil WB7AEI ------------------------------ Date: Wed, 28 Jan 2004 09:55:14 -0800 From: "John Dooley W6ZIP" To: qrp-l@Lehigh.EDU Subject: [166474] Need help with schematic for RS power supply for ham in Iraq Message-ID: Mime-Version: 1.0 Content-Type: text/plain; format=flowed Received an email from Dwayne Barbee, KE4RVT/YI9RVT.

I have four full-size dipoles in the attic for 80, 40 , 30, and 20 meters, all fed in parallel with RG-213 and a balun. They are clearly noisier than my outside antennas. I use the ANC-4 and find that for some noise types with any of the antennas - there are four more outside - it can be very effective. Also, it can significantly reduce some local signal sources. For example, my router places a couple of weak carriers around 7037-38 kHz which is prime Fox country. I find that by careful adjustment of the ANC-4 I can reduce the heterodynes almost down to band-noise level. Also, the Manual Notch on the PRO2 and 746PRO will reduce the carriers, but that is another story. I have used the NIR-12 for several years and it remains in my view the best outboard audio DSP unit. I presently used it on the output of my PRO2 to control the higher frequency noise that is associated with the narrow DSP IF filter bandwidths. It affords two NR functions and a most effective auto-notch. These are no longer being made, but are an excellent unit if you can find one used. They are superior to the NIR-10 in that they use two DSP processors and can support all functions concurrently.

But to a 10-year old, just how appealing is the process? And what is the purpose, for him/her, of listening to "shortwave" radio in this day and age? My experience with my own grandkids is that among computers, IM'ing friends on the Net, video and computer games, and CD music listening, building and then spending time listening to a shortwave radio doesn't stand much chance of catching their attention or interest. Not trying to rain on any parades, but I think that perhaps we err in projecting our own interests - coming from another background in time - upon a group that we would earnestly like to help enter this great hobby of ours. Having said that, more power to those that are trying since there will always be a few youngsters that will be touched by the "magic" as I was at an early age and who will start their journey at that point.

Most internal tuners cannot handle such a high impedance and thus cannot tune the antenna. One approach would be to shorten the wire to about 67 feet which would then have a "low impedance" at the feedpoint and your tuner could probably handle that OK. You would have to use a so-called counterpoise or "driven ground" with such a setup, but that is another story. But on 40 meters, the end feedpoint would again have a high impedance and you would have the same problem you are having now. An external tuner is one way to handle this problem, especially if you want to operate more than just 80 meters. The better solution is to feed the antenna in the center with ladderline or twinlead and use an external tuner Hope this helps a little . . . 73, George W5YR w5yr@att.net ----- Original Message ----- From: "sergio" To: "Low Power Amateur Radio Discussion" Sent: Wednesday, January 28, 2004 12:59 AM Subject: longwire and 80m.. > > i have a longwire that i am tuning for 80m.. > > i had some trouble tuning it on the hw-8 until i started running all my > gear with a battery.. > > since then, it ran well.. > > when i got the ts-520, and the autotuner.. i suddenly found that i couldn't > tune 80m on that antenna to save my life.. > > the wire is about 130 feet long.. > > is this the problem? the length of the wire? ------------------------------ Date: Wed, 28 Jan 2004 13:51:03 -0500 From: Bruce Muscolino To: leon_heller@hotmail.com Cc: Low Power Amateur Radio Discussion Subject: [166479] Re: longwire and 80m..

Yes, certainly a "true" long wire is one that is several wavelengths long. But I challenge you to identify very many hams who have the real estate to erect such a "long" wire a any ham band below 40 meters! Hams have traditionally used long wire to mean any piece of wire, almost any length. 73 ------------------------------ Date: Wed, 28 Jan 2004 13:18:10 -0600 (CST) From: Dale Botkin To: Low Power Amateur Radio Discussion Subject: [166480] Re: DC vs. Superhet for beginners?

Scout campouts and a code practice oscillator, or HF rig, are a sure way to get some undivided attention!

I agree we're not getting it quite right -- so any suggestions you've got are appreciated.

They buy it, plug it in, and it does it's technological wonder for them. The kids can definitely interact with it, and in the case of programming, can be creative. But these kids have virtually no knowledge of what's happening "under the hood". Every year, I buy a Christmas present for my children that allows them to make something useful. Some items that come to mind are: "Make your own lamp", "Cotton Candy Machine", "Make your own Jewelry", "Make your own soap", "wood burners", **Shortwave receiver kit**, etc. These toys consistently turn out to be my kids' favorite present, and now that they're grown up, they STILL ask for presents of this type. My point? While kids today are incedible technological operators, what is "mysterious" to them is HOW things work. What is "WONDEROUS" to them is that they can actually make something for themselves rather than just buying it and plugging it in. Disagree? This year's HOT toys were.....Can you guess?....Do it yourself kits! If attracting kids is the goal, go ahead and kit a useful receiver that's easy enough for a 10 year old to build. Even if it's not spectacular as a serious receiver, it'll whet their appetites and might even make them explore radio further.

R1155's, ARC-5's etc., we also had societal problems affecting young people. We had our share of "dead-end kids", "ducktails", "motorbike boys" etc. (Usually a stint of National Service in HM Armed Forces straightened them up, though. The good ones went into Royal Signals and learned radio.) But we also had kids animated by imagination and vision back then. Many of them became interested in ham radio, SWL'ing and other radio-related hobbies, and went from there to careers in electronics, radio communications and telecom - as I did.The point I was attempting to make in my original post was that the paradigms have shifted vastly since then, and the shift seems to have escaped the notice of many of us in the "elder" generation.

The kids are stimulated with a barrage of images from TV, videos, and games, but these are not necessarily good stimuli. Young people read less, exercise less and DO less than the previous generations. Incidently, reading and listening for that matter cause more brain activity than watching. Yes the kids are inundated with tecnology but mostly their involvement is pretty much passive. I work in an engineering lab that often employs students and graduates. I find it amazing how a young person can come to work with a degree in engineering or computer science and know virtually nothing practical about the tools of his trade. Mechanical engineers are not very familiar with machine tools and have great difficulty designing parts that can be fabricated. Electronic engineers don't know how to solder and have minimal parts recognition skills (and that's just the beginning). Computer science grads think anything can be simulated and that prototyping is unnecessary. Are these kids smart (intelligent)? Usually. Are they educated? Hardly. Have they wasted most of their young lives on trivial stimulation. Definitely. Believe it or not there is a crying need for people willing to help kids learn to use their brains by building stuff--that includes simple radios or kites or telescopes or doll houses, etc. Is their competition for their attention? Yes, way too much. Most of the challenge involves getting their short attention spans directed to something positive and helping them learn to apply themselves to constructive, hands-on pursuits. It is a challenge to get their attention and help them, but it is also one of the most rewarding things you will ever do. If we want to compete in world markets in the future we have to do something now--like start looking around your own familly or neighborhood for an opportunity to help a young person develop REAL and useful technical skills. Having said all this, I admit. There are exceptions, but they are exceptions--not the rule. I say turn off your radios for a while, buy a kit, and help some youngster in a way that will do him permanent good. Bruce kk7zz P.S.

Telecom and communications hardware has become totally trivial; in fact, today it seems to be no less a commodity than electrical supplies or computer hardware. Who is going to build or even repair a NIC or a HDD controller in this day and age? Today's equivalent to the youthful crystal-set and regen builders of our childhood years is much more likely to be sitting at a computer, configuring an 802.11g network to give his friends in the neighbourhood high-speed access to the NASA interactive site I mentioned in my original posting. The do-it-yourselfer of this generation will be writing and debugging code, whilst others in the electronics factories of Taipei and Shenzhen sniff the rosin (unless automated wave-soldering lines whisk the solder-smoke away.) This is a trend which our emotions, and our memories, render very difficult to accept without pain. For our generation, which grew up with radio and radio hobbies, the attraction of a radio project is instinctive. But sadly, I cannot see getting a bright pre-teen or teenager, for whom the Internet has already opened the gates of the universe, interested in exploring the shortwave bands - especially with a poorly-performing regenerative receiver. That kid, accustomed to CD-quality audio, will not even tolerate the nasal sound of 6K00A3E AM, with its selective fading etc. Not even the argument of loss of Internet service in times of emergency will wash - tell the kid that, and he may well rise to the challenge by becoming a telecom engineer and devoting his career to hardening the Internet (today's Library of Alexandria). Sadly, the chances of his acquiring a ham licence in the process will be quite remote.

Soldering is the real issue not the number of parts. - most will not experiment with DC then add parts to a radio to turn it into a superhet.(?) -As one suggested, focusing on "low power can do this" as opposed to "look at how few parts this marginal radio has". Kids aren't impressed with "pong" and won't play with it long. -People that want to see some of the potential of qrp can experience some of the excitement by turning down the power on a "big" or qro radio. If they enjoy that, then they can follow with a good qrp rig and catch some of the excitement that comes with making contacts on a radio that you built yourself. -Elmering into this aspect of the hobby- the consensus is that it is a good thing. How you do it is of less significance. Kids don't learn by a one size fits all methodology. The professional educators can explain this further. Often it is the person and their own effectiveness as a communicator that determines the success of failure. As far as all time favorite radios....The SW and DSW radios seem to offer the most bang for the buck and the most enjoyment to their users. (according to the feedback) Other points of view were similar to the code vs no code, and dumbing down the hobby discussions.

My experiance and yours is with previous kits that had a crystal oscillator on 7.040 and something to rubber the crystal a few Hz. This kit radio will be a direct conversion receiver with a frequency tuning knob, just like a Superhet. It will tune from below 7.000 to over 7.400 MHz as I understand it. There is nothing wrong with a direct conversion receiver provided it's well designed. My fear is that this radio not having any integrated circuits is missing some great capability that comes cheap in a chip.
