There's a fundamental problem with that viewpoint - see below. we/I see amateur radio simply interfacing to the net as seamlessly as the other forms of communications are/have done ... I frequently use magicjack/voip--I am certain this worries AT&T ... the possibilities with amateur radio are mind boggling -- and YET to be developed. There's a difference between what can be done and what should be done. This means, your amateur broadcast may begin on your xmitter, transverse a cell tower, a hard phone-line, a trans-atlantic cable, satellite, etc. before it arrives at the fellow amateurs' shack--in Australia!--and the packets decoded to voice/video/data. The problem is that such a mindset as you describe misses a fundamental point about what amateur radio is all about. Indeed, it misses a fundamental point about what *life* is all about. What you describe is what could be described as "the mindset of the destination" or "the mindset of the message". Meaning all that matters is getting there, not the method or the journey. And for a lot of things, that's perfectly OK; I don't really care what exact path or technology routes my phone call or my email as long as it gets there reliably and at low cost. Most people don't care if the TV show they watch is delivered by magnetic tape, optical disc, RF in the air, RF in a cable, or light in a fiber, it's the program content that matters to them. But there's another mindset to consider as well, which can be described as "the mindset of the method" or "the mindset of the journey". It's the mindset where the route, the technology, the experience, etc., *do* make a difference to the person. In many cases the journey is more important than the destination. And it's a big part of what Amateur Radio is all about. Because one of the main reason for Amateur Radio to exist is that it is "radio for its own sake". A thing done for its own intrinsic value to the doer, not just for the final result. It's like asking why anyone goes fishing non-professionally when they can buy fish cheaper at the market. Or why anyone rides a bike, walks or runs when they have a perfectly good car, or cooks when they can go to a restaurant. Why anyone would paint or draw when there are perfectly good cameras of many types. The answer is that they are doing those things for the doing, not just for the end result. A QSO from my radio to another ham's, direct by ionosphere, troposphere, aurora, etc., is not the same journey as a net-simulation, just as my homemade bread is not the same as a loaf bought in a store. More than ten years ago, I saw discussions about how practically all that we radio amateurs do on HF from fixed points could be done on the net using various forms of simulation/emulation. And I'm sure it could be done. The folks who proposed this simply didn't understand the difference between the journey and the destination. That difference is very important. --- There's another factor: Having an alternate system. Too much dependence on a single system is not always a good thing, because when (not if) that system fails there's no alternative - no backup. Too much dependence on a single system also stifles creativity because all thought tends to be conditioned to that system. -- None of this means Amateur Radio must never ever connect to the 'net or to other communications systems. What it does mean is that such connections are an enhancement and/or interface, not a replacement for "A Boy And His Radio" (to use K0HB's phrase). 73 de Jim, N2EY |

A bit of history may be in order.
Going back many decades, international radio spectrum managers (ITU/IFRB) designated several slices of spectrum for Industrial, Scientific, and Medical uses on a regulated-but-non-licensed basis. The most famous of these was the former 11-meter Amateur Radio band, centered around 27.12 MHz (Mc/s in those days) and the 960 MHz and the 2450 MHz bands where the "WiFi" stuff eventually landed. These bands were and to most of us still are considered "electronic garbage cans" and Administrations could allocate uses of those spectrum slices on the basis that the users had to accept any interference from ISM operations. The FCC decided to establish a class of non-licensed low-power operations regulated under what is now Part 15 which could operate in those spectrum spaces. The 11-meter band was allocated to the Citizens Band Radio Service, which at first was a licensed service but became "blanket authorization" when the renegade violators decided to ignore the law and the FCC caved in (if you can't beat 'em, join 'em). At the same time, ISM operations - which in general were high power with lots of harmonics) moved to screen rooms or elsewhere in the spectrum because their harmonics were causing interference in the VHF Aviation band. leaving that portion of the spectrum to the CBers. This more-or-less orderly Part 15 operation lasted for a while until the FCC, in a stroke of lightheadedness, no doubt prodded by equipment manufacturers with product to sell, decided to allow Part 15 operations on other portions of the spectrum allocated to licensing users. There was quite an uproar while that was being proposed, and the objectors were told to "sit down and be quiet". In other words, it was a done deal where politics or ideology overruled competent spectrum management. -- 73 de K2ASP - Phil Kane From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon e-mail: k2asp [at] arrl [dot] net |

As a person who works with computers every day, I have to say that trusting one's well being would not be the wisest of moves. I would rather trust that there is some way of getting an rf signal through. - 73 de Mike N3LI - |

I often wondered if it took out all the CB Receivers in 20 miles when he fired it up. Had to plugged into 220 Vac. One of the true pleasures of (a) self employment and (b) a niche market is I get some really odd service requests in the shop. About a month ago a doctor calls about his diathermy machines. 4 new sweep tubes and a couple of oscillator doubler tubes and we're back in business with 1600 Watts Peak pulse on 27 MHz. It really did look like some Flash Gordon death ray machine. What I found amusing was when I took it back to his office, his method of testing it was to light it up with the antenna against the small of his back, then hold up the light socket with the coil of wire on it to his stomach and twiddle the knob for maximum brightness.
