With all due respect, this is far from a college-level course. I have limited expectations that the attendees will spend vast amounts of time studying outside of class, and frankly I rather hope that that time will be spent taking practice exams. I think it's unrealistic to expect that if I "assign readings" anyone will actually read them. I disagree! The readings can be handouts of a few pages. Introductory stuff with links to more advanced things. This would be a fine strategy if my primary goal were to teach concepts, but my primary goal is to get these students a passing grade on the test. Sorry, but that's just the way that it is. I don't think it's appropriate for me to teach actual practice to people when they first need to pass their written exam. Then you're essentially "teaching the test". And with all due respect, that's a mistake IMHO. Here's why: I think that we hams have sometimes placed too much emphasis on getting lots of people licensed rather than educated and licensed. The result is folks who are licensed amateurs but don't really know how to get on the air. They're then left without the structure of a class, to learn what's needed to actually use the license. A recent statistic from ARRL said that 22% of new hams had *never* gotten on the air with their new license. To me, that's a direct indication of putting the license ahead of the knowledge needed to use it. What I would *like* to do is teach a followup class on what people need to know to get on the air -- how to select equipment, what actual antennas are like, operating procedures, and so on. But I simply cannot do that *and* teach them enough to pass the written test in the amount of time available. I consider my first priority getting them past the written test, then we can work from there. Perhaps the handouts could cover the practical stuff. If time is that limited, then IMHO its purpose is to guide rather than to be comprehensive. I have to add, and I don't want to sound condescending, but I know that some of the people who will attend this class are barely literate, much less capable of reading and understanding the question pool . . . even though it's written at a junior-high level. Who *are* these folks? I mean, the current written exams have been passed by elementary school children years away from middle school. I suggest that if you have low expectations, the class will live down to them, and if you have high expectations, they will live up to them. This may be another challenge that I have -- how can I keep the intelligent people in the class interested when the dumber-than-a-rock crowd doesn't even understand the concept of what a frequency is? With all due respect, if someone cannot grasp the concept of what a frequency is, they should not be a licensed radio amateur, IMHO. Such a lack of basic radio knowledge means the person just isn't qualified yet, and endangers both the person and those around them. The whole point of license testing is to insure that licensees know the basics. The Tech license is not an ideal entry-level license. Agreed. But it's what we've got. It requires quite a bit of intimidating work to learn material that is pretty foreign to people who have no experience in radio. I disagree. It all depends on how the material is presented. To use the frequency example, while most people might not know a kilocycle from a bicycle, they will probably know that a piano produces different tones. A simple electronic keyboard can demo that principle easily. Then it's a short step to different radio frequencies. Of course it must also be learned that there's a difference between sound as vibrating air and radio as a vibrating electromagnetic field, but that's part of the game. Once you've got the license you need someone to demonstrate the wonders of HF, else there is no incentive to upgrade. Why not as part of the frequency demo? How about a long roll of paper with various frequencies on it - 60 Hz for power, the AM BC band, the 49 MHz baby-monitor band, VHF and UHF TV, FM BC band, cell phones, microwaves, and oh yes, the ham bands. Color code it for the various services. What I'm looking for is a real entry-level license, similar to the Novice ticket, with an incentive to upgrade. I want to be able to actually teach concepts and the real skills that people need to get involved in ham radio, without feeling that I cannot do so because my limited time must be spent getting them the knowledge to correctly pick answers to pool questions. Then you need more time. It's that simple. The time can be class time, or it can be time the students spend reading and learning on their own. But it takes time to learn this stuff. "If it were easy, everybody would do it." 73 de Jim, N2EY |

I probably shouldn't sell the students short until I see who actually shows up. That's a big part of what I am saying. But the impetus for the class was a request from a couple of people who have already attended two previous entry-level classes taught by the radio club in the next town over. I saw their material; it's good; anyone who managed to attend their class and not pass is either unmotivated or unteachable. I'm not convinced. Did you sit in on the classes and see what was actually presented? Were the students able to attend all the classes or only some? Good material, by itself, isn't going to guarantee success. I suggest that if you have low expectations, the class will live down to them, and if you have high expectations, they will live up to them. You have an excellent point, and I will try to act on it. Thanks On the other hand, I do have to be realistic. I have to adapt the material to the level of the people in the class, to the best of my ability and striving not to pitch it so low that part of the class gives up in disgust. That's true of any class, isn't it? Particularly one where attendance is 100% voluntary. With all due respect, if someone cannot grasp the concept of what a frequency is, they should not be a licensed radio amateur, IMHO. Such a lack of basic radio knowledge means the person just isn't qualified yet, and endangers both the person and those around them. I think you've gone too far because I went too far in my example. I stand by my statement. There must be certain minimum qualifications to be a licensed ham. That doesn't mean a high level, but it does mean all hams should know the basics of how radio works. Otherwise the whole purpose of the ARS is undermined. The students in this class live in rural Minnesota. Electronics is foreign to most of them. They can run a GPS-controlled tractor and cover their fields without double-spraying a single row, but don't expect them to understand the concepts of how GPS works. Or want to. I'm not saying they should understand GPS to a high level. But being from rural Minnesota doesn't mean they are incapable of understanding basic radio if presented properly. It's a real challenge to teach electronics to this demographic. For one thing, their motivation to learn the material is 100% related to passing the exam; they really couldn't care less that 1 amp will flow through a resistance of 1 ohm if 1 volt is applied. They don't have to *like* it, they just have to know it. Some of it I can make "real" -- bring in a long extension cord, measure the resistance, discuss what that means when you put a welder at the end. BINGO! That's exactly it - tie the seemingly-abstract theory to a real-world practical example. Another would be a demo of why short thick jumper cables are better than long thin ones. I can tell you from personal experience that most of a teacher's job in such situations is finding an explanation that can connect what the student already knows to what is being taught. Most of these folks will never be electronics gurus. They don't need to be. They need to understand enough concepts to understand how to operate the equipment that they buy. Agreed. The license tests are the starting point, too, meaning the person who passes them has met the *minimum* qualifications, not that the person is an expert. Do they need to understand the relationship between wavelength and frequency to do that? Yes! (IMHO) No. Sorry, that's one of the most basic things about radio there is. All it really requires is an understanding that low frequency = long waves and high frequency = short waves. The whole point of license testing is to insure that licensees know the basics. I'm not sure that's actually true. Why do we care that a Technician licensee knows Ohm's law? Because it's basic to the operation of radio. Real world example: There's a lot of electronics out there that requires a certain minimum voltage to work properly. Typically 11.5 volts or so for "12 volt" equipment. Some things, like camcorders, have automatic minimum voltage shutdown. Most ham gear doesn't have such protection. At least some amateur transceivers will emit spurious signals if you try to transmit with them using too-low supply voltage. Synthesizer unlock and similar stuff. Spurs that can cause interference to other radio services. On top of that, most rigs draw a lot more current on transmit than receive. So if our new Technician doesn't understand Ohm's Law in at least a very basic way, s/he could hook up their rig using wire that has too much R, and then transmit all kinds of spurs because the rig is getting too low a voltage on transmit. Yet it will receive perfectly because there's enough voltage when not transmitting. Indeed, the ham could even start a fire by overheating the power supply wires. It seems to me that the point of license testing is to erect a barrier to entry. If that were not the case, the license pool would look a lot different. It would consist of regulations and practical knowledge that was actually used on a day-to-day basis. It would consist of material that, to use your phrase above, is essential to insuring that the licensee is not a danger to the person and those around him. Ohm's Law isn't just theory. An understanding of it is a practical necessity for radio amateurs. Otherwise they're not qualified to do what the license allows. Then you need more time. It's that simple. The time can be class time, or it can be time the students spend reading and learning on their own. But it takes time to learn this stuff. But I don't have more time. Doesn't have to be *your* time. It's going to be hard enough convincing people to come to six sessions spread over three weeks. If I asked for more time, I would get no students. How do you know? The goal is to figure out how to best use the time I have. If I'm really successful, I will be able to lure people back to a followup class. That's the only way I'll ever get access to more of their time. At a certain point, they have to be interested enough to invest the necessary time and effort. "If it were easy, everybody would do it." And we're back to the concept of the exam as a barrier to entry. No. It's not about "barriers". It's about a ham knowing the basics. If you have zero barrier, you have CB. I would phrase it as "zero requirements". But yes, you have cb. And look how that turned out. Should amateur radio become nothing more than high power multiband cb? I say no. If you have infinite barrier, you have no one entering. Of course, but the license requirements are far from infinite. They're just the basics. 73 de Jim, N2EY |

Reading all the back and forth discussion of Steve's upcoming classes and
his concerns... I'm getting really confused. When I was a teenager playing with CB, I didn't know nuthin' from nuthin' about radio, antennas, you name it. Once I became determined to become a ham, I eagerly learned all about it in order to pass my Novice, and then the General, and.... and at points when I saw the need (such as "gee, what is this 'swr' business?"), I learned more. So Steve, if you're so concerned about how these "students" are going to respond to your technical talks and related licensing materials, why are they even invited? Are they really interested in becoming hams? Or (at an extreme), are you recruiting potential hams like "Psssst! Hey kid - come 'eah - you wanna get a ham license?" If they're going to whine about "Why do I have to learn this stuff??" then *I* don't think they deserve the privilege of a license. Howard N7SO |

I was and still am like that. A lot of radio stuff I learned simply because it looked interesting or might be useful "someday". But not everyone is like that. Doesn't mean they can't be good hams. So Steve, if you're so concerned about how these "students" are going to respond to your technical talks and related licensing materials, why are they even invited? Anyone with interest is invited. And any good teacher tries to match the presentation to the students. Are they really interested in becoming hams? *That's* the key question. Or (at an extreme), are you recruiting potential hams like "Psssst! Hey kid - come 'eah - you wanna get a ham license?" Well, it's not quite like that! The way I see it, people with interest should be welcomed and helped. But the person has to take a certain amount of responsibility to learn what's needed and to get set up. There's a point where "help" turns into "doing it for" in such a way that it actually works against the goal. It's the old "give a man a fish/teach a man to fish" thing, aka "learned helplessness". If they're going to whine about "Why do I have to learn this stuff??" then *I* don't think they deserve the privilege of a license. It's not "whining" to ask why the requirements exist. All license test requirements have to justify their existence. The Basis and Purpose of amateur radio includes the idea that hams will know at least the basics of radio. Ohm's Law and the relation of frequency and wavelength are pretty basic radio stuff, therefore, they belong on the test. Simple as that. 73 de Jim, N2EY |

If they're going to whine about "Why do I have to learn this stuff??" then *I* don't think they deserve the privilege of a license. Let me try to address your questions and comments from Jim. I understand what you are both saying, and agree with much of it. But we have some basic disagreements. Let's remind ourselves of the five purposes of the amateur radio service from Part 97: (a) Recognition and enhancement of the value of the amateur service to the public as a voluntary noncommercial communication service, particularly with respect to providing emergency communications. (b) Continuation and extension of the amateur’s proven ability to contribute to the advancement of the radio art. (c) Encouragement and improvement of the amateur service through rules which provide for advancing skills in both the communications and technical phases of the art. (d) Expansion of the existing reservoir within the amateur radio service of trained operators, technicians, and electronics experts. (e) Continuation and extension of the amateur’s unique ability to enhance international goodwill. Items b, c, and d require technical knowledge of radio. Items a and e do not. There are two reasons why I do not expect the students in my entry-level class to develop a detailed understanding of electronics. First, this knowledge is not necessary in today's hobby. Sure, it's desirable, and it's necessary if you want to actually get involved in certain aspects of the hobby, like building your own equipment. But it is perfectly possible to participate in emergency communications, or to enhance international goodwill, and not know an ohm from an amp. Second, most people today simply do not have any desire to learn radio theory. Does that mean that these individuals should be excluded from the ham radio hobby? I do not think so. It's certainly your prerogative to believe differently. Related to this, I know that most of these folks are "learning" this material simply so that they can pass the test and that within a couple of weeks they'll retain none of it. If that bothered me, I wouldn't teach the class. In short, my goal is to get some new hams licensed. At worst, they can fulfill two of the five stated goals of the service. At best, they will discover the wonders of the hobby and get involved, and in that process they'll learn a lot more because they want to. I hope that I can help them get involved, but they'll never get involved if they don't pass that first exam. I have about 18 hours of one-on-many time with these folks. I have to figure out how to "best" use this time. "Best" is really what we're talking about in this subthread. I'd love to give them a good electronics background, but that's simply not possible in 18 hours. My primary goal is to get them through the exam, and that factors into my definition of "best use of time". I don't think that my standards are too low. I would rather give these folks an opportunity to be productive members of the ham radio fraternity than to insist on a burning desire from the beginning to learn about radio fundamentals. |

If I may interject here, I think we may be treating people as a group more so than individuals. Some of those people in your class may just want to fire up the repeater and chat. Some of them may just want to do emergency comms. Some may want to build stuff. Very importantly though, they may not know until they are exposed to it. When I first became a Ham, my interests were in applying the hobby to my other hobby, amateur astronomy. After that, I joined a club, and went to FD. I operated Field day with a control OP. I thought WOW! this is a lot of fun. So I went for my General Test. After Struggling with Morse Code - it is not easy for some of us, I got my General Ticket. Then I discovered Digital modes, and a whole new part of the hobby opened up for me. I kept on discovering things, the latest being how enjoyable HF Mobile is. I built my own bugcatcher, and have been surprised how well it works, given the low efficiency of mobile antenna setups. My point here is that I discovered a lot of things about Ham Radio that I didn't expect, and they became the focus of my hobby. Oddly enough, I never integrated Amateur radio as I had originally planned to, in Astronomy. Don't sell the students short. Some of them may indeed just want to "pass the test". But by exposing them to a little of the different aspects of the hobby might just awake something in them that they didn't know existed. Some thoughts for demos: Obvious ones like the repeater operations. An FT-817 with a miracle whip might be just the ticket for demonstrating SSB, CW and Digital. With all the "hot" setups out there, a less than mediocre setup such as this will still be able to make QSOs with. I'd suggest going from FM to SSB to PSK-31, to CW, just to keep things lively. Could be done by bandwidth, with an explanation of how the smaller bandwidth signal tends to get across better. It's always good to have a sked setup with another Ham in case propagation is bad. - 73 de Mike KB3EIA - |

Steve, from all the talk of the others and your very patient replies, I think you are doing the right thing with your preparations. It is very basic stuff you are doing and that is a good step, perhaps the best step for your Class of collected tabula rasas. I applaud your efforts. Since I've been involved in radio and electronics (one way or another) for 6 decades, making the "Compleat Ham" (as Phil put it) just can't be done in 18 hours. It would take at least a thousand hours, perhaps two. Had it been that long a 'class' the drop-out rate would be large. As you say, some aren't interested in theory, some are only interested in certain aspects of radio. Those who only want VHF and up operation probably could care less about the ionosphere and all that long-distance propagation. But...the thing others haven't mentioned or others just gloss over is that you HAVE some that are interested enough to come for 18 hours. "The journey of a thousand miles begins with a single step." So far, the 'discussion' has been a lot of argument by others all about stepping, which way to go, etc., etc., ad something or other. I doubt that anything of that applies. They have taken the first nibble of the bait and aren't yet hooked, but I sense you can play them in. PRESENTATIONS of anything are always better with a sense of theater about them. That involves the personality of the presenter, the prime focus of all in this classroom. Their interest must be held and focussed on the material and that comes from their sensing the presenter' mood and personality. Projection of the presenter to this 'audience' requies confidence and a friendliness with them. Preparation and presentation go hand-in-hand. It is nice if you can do some audio-visual things but simple, easy-to-read-at-distance graphics will do. It breaks the flow a bit, but that's good. It lets the class focus on the material; they don't always have to watch the presenter. Being at ease in front of an audience is sometimes a toughie. It was for me the first few times, but I adapted to it. The ease of the presenter is absorbed by this 'audience.' Lack of ease will reflect in the audience drifting away from the presentation and they may feel uncomfortable. Since I'm a bit far from you, I can't watch a rehersal of your presentation and suggest some improvement, but maybe there's one or more there who would be willing to stand in for the 'audience?' I don't know how much experience you've had before such an audience but I think you will get the feel of it right quick. You know the material. The only thing left is letting your enthusiasm rub off on the folks in class. You've made the first step for them. Now it is time to extend your hand to have them follow. I hope they ALL follow you...and eagerly. 73, Len AF6AY |

They are "made" by participating in the hobby. Traditional classes should be a part of that participation (I have little patience with the people who say, "I don't have time to attend your class on emergency communication or participate in your exercise, but I'll be around when there's a real emergency") but experience is the real teacher. And you can't begin that experience until you pass that first written test. As you say, some aren't interested in theory, some are only interested in certain aspects of radio. Those who only want VHF and up operation probably could care less about the ionosphere and all that long-distance propagation. But...the thing others haven't mentioned or others just gloss over is that you HAVE some that are interested enough to come for 18 hours. One of the things that continues to amaze me about the hobby is that it's not one hobby, but many. That's one of the things I hope to be able to communicate to the students in the class . . . not by preaching to them, but by describing the various aspects of the hobby (or by having someone who is passionate about "their" aspect come to class and expound on it). I do think that those who only want VHF should at least be exposed to propagation and how it works; how can they know if they might be interested in HF if they never even know it exists. "The journey of a thousand miles begins with a single step." The journey into the ham radio hobby begins with passing a written exam. I suppose that's not really true. The journey begins with deciding to take the journey. For these students, the "single step" is attending this class. That fact sure puts the pressure on the instructor . . . So far, the 'discussion' has been a lot of argument by others all about stepping, which way to go, etc., etc., ad something or other. I doubt that anything of that applies. They have taken the first nibble of the bait and aren't yet hooked, but I sense you can play them in. I hope so. Time will tell. As a related comment . . . when I started this thread, one of the issues I was trying to explore was walking the tightrope between "teaching the pool" and teaching a general electronics class. As I continue to prepare the details of the class, I'm realizing that teaching a concepts class based on the pool questions isn't really that bad. If the students come out of the class understanding the concepts upon which the pool questions are based, they will have a pretty good start at an electronics background. There are some huge gaps, of course. For example, somehow the concept of inductance doesn't appear at all. But after living with the pool for a while, I feel better about using it as the basis for an 18-hour introductory class. I'm sure that some of the students will spend their study time memorizing the specific questions from the pool. I hope that I have some students who will embrace the concepts. All I can do is present the material in the clearest and most engaging way that I can, let my passion show through, and provide the mentoring and encouraging environment to get them into the hobby. Since I'm a bit far from you, I can't watch a rehersal of your presentation and suggest some improvement, but maybe there's one or more there who would be willing to stand in for the 'audience?' I don't know how much experience you've had before such an audience but I think you will get the feel of it right quick. You know the material. The only thing left is letting your enthusiasm rub off on the folks in class. I don't mean this to be critical of your suggestion Len, but I'm reminded of an article I saw last night on the network TV news. It seems that FEMA decided to give a news conference, and when no reporters showed up, FEMA employees pretended to be reporters and asked questions of the FEMA presenter. I'm afraid that rehearsals of this class, which would likely be held with members of the local radio club taking the place of the students, would be a lot like that. It would certainly be useful to do it, and I'm sure my presentation would benefit, but the "audience" that I get for the real class is likely to be much different from the "audience" that I would have in a trial run. I think that the single biggest challenge I'm going to have is finding the right "pitch point" for this class. I'm expecting to have a few folks whose eyes glaze over as soon as I try to cover anything even remotely difficult and a few who will think that my level of coverage is much too general. Trying to keep the interest of the one group and not bore the other is going to be a challenge. I hope I'm up to it. 73, Steve KB9X |
