Transmitting 50 kilowatts from a single site capable of covering most of North America, using groundwave propagation, independent of solar activity, is an "outrageously inefficient way to distribute a small quantity of information?" Well, I do hope that you are hurrying to write your Congressman to demand that the National Institute of Standards and Technology put an immediate end to this grave outrage, and profound waste of taxpayer's money that has been going on for decades. After all, what does the NIST know about technology, or useful communications? Perhaps as little as the engineers and marketers in the economically successful and useful product field of WWVB watches and clocks, in your estimation. Wouldn't it make more sense to include WWV and WWVH along with WWVB? Are you familiar with the Internet-based ntp system? Then, there is the matter of GPS, which has a time capability that is incidental to its navigation function. [...] I think you are underestimating the power of SMS. As for the comparison to E-mail, I don't have to ask, as journalists have already done so, including this recent article from Slate: http://www.slate.com/id/2177969/pagenum/all/ Simply put, young people find appeal in the immediacy of small, but low-latency messages sent in relatively large numbers over a long period of time, and the information transmitted is far more rich and meaningful that what you imply above. In many respects, this type of communication is not stilted or limited, but almost provides the immediacy of a conversation, without having to run up your voice minute charges or leave your other callers unable to reach you due to the long-term busy signal. Young people do still use E-mail, but in circumstances for which it is the better choice. They are not seeking some overall best "general purpose communications" to get their messages across to each other. I don't see anything in that that contradicts my statement that SMS is mainly used for messages of little importance. It is also called CMS, for casual messaging service. I didn't realize that only "general purpose communications" were considered worthwhile. A multi-purpose system that can match a single-purpose system on the performance of the objectives of the single-purpose system is generally, if not universally, considered superior. Your previous reply argued that it was undesirable to use such a low-speed technology as Morse code given that there were many higher-speed alternatives (faster by "orders of magnitude" you said). I replied to you that fastest is not always best. Other issues (previously enumerated by me) might actually dictate the choice of lower-speed communications as the best choice. I also don't see "general purpose communications" mentioned in Part 97. Many "single purpose, dedicated systems" are used by amateurs, and help fulfill amateur radio's Basis and Purpose. In many cases, a "single purpose" technology is far more useful than a misfit, one-size-fits-all, "general purpose" one. Before we make too many assumptions about an undefined term, perhaps you can describe what types of "general purpose communications" you would consider to be worthy goals for the Amateur Radio Service, and which "single purpose" technologies you would like to see eliminated? Why do you want me to reinvent the wheel? Lets go to the source (condensed from Part 97.1): * emergency communications * contribute to the advancement of the radio art * advancing skills in both the communication and technical phases of the art * expansion of the existing reservoir within the amateur radio service of trained operators, technicians, and electronics experts * continuation and extension of the amateurs unique ability to enhance international goodwill Would you also kindly define what is a "single axis of data," in terms familiar to those involved in communications engineering and technology? A single quantity, like time or location What, then, would be "multiple axes of data?" Two or more simultaneous quantities, like time AND location or course AND speed. So, in other words, you are actually agreeing with my previous reply to you that there are many useful Morse code based communications technologies that do not actually require memorized, in-head, copy of Morse code. I'm glad that we agree on something. There is probably no purpose for which Morse can be used as a machine language where there isn't a choice of other, better suited languages available. This includes aeronautical beacons. You are grasping at straws, now. Wow, these curmudgeons must have been very powerful and effective in their obstructionism if they undermined entire areas of communications technology development in this country over the last 30-40 years. I didn't realize that our national technology infrastructure was so inflexible and lethargic that it could not recover from these influences, even after so many decades. When you look at the development of the Internet, Linux and other free software, you have to wonder about the infrastructure behind it. How did it come about? There was no regulatory body. There were no licenses. There were no "Elmers." Until recently, there wasn't even any formal schooling available, except on the sort of machinery that existed only within the Fortune 500. Early Internet users and developers had to read O'Reilly books and figure it out on their own. That showed great initiative. It demonstrated the sort of determined, driven advancement of technology that was once seen in amateur radio. But that sort of thing has passed ham radio by. It has been a long time since ham radio was a source of innovation. I blame the Morse cultists who hijacked amateur radio for use as their personal playground. Just the introduction to your previous article, where you directly compare the Baud rate of Morse code with that of "obsolete" telephone modems. You stated that their data rates differed by "orders of magnitude," implying that communications technologies that were "orders of magnitude" slower than telephone modems could be dismissed as obsolete. An amusing interpretation. It follows that trains and ships should be discarded because they are much slower than airplanes. Following the natural extension of that argument, then the only technologies that could be favorably compared to such telephone modems, and meet your argued standard of non-obsolete, could only be realized on high VHF and up. As I argued previously, use and advocacy of Morse code has no bearing on the current deployment of such technologies, as no Morse code test has been required to access them for at least 17 years. The Technician-class license has existed for far longer, and has only a minimal Morse code examination. You left out the faster mode of communication known as "voice." It is widely used on HF. Further, I once looked at a band plan that showed how DV could be used on HF. They described a system of HF DV that took up just slightly more bandwidth than SSB and substantially less than AM. So, to summarize: slow-speed (less than 100 baud) PSK31 : "Good" similar order-of-magnitude speed Morse code: "Bad" So, it's not the speed you object to, it's the use of Morse code? Couldn't you have just stated that, and not gone to the trouble of bringing in other arguments like speed and bandwidth, or whether a communications technology is sufficiently "general purpose" or not, regardless of whether something "general purpose" would be the best choice in a given circumstance? Just say that you don't like Morse code. Others would at least give you credit for honesty. Who are these "others" and when did they appoint you as their spokesman? References please? A Google search returns no evidence that Navy stations like NAA in Cutler, Maine have gone off-line. Are you possibly thinking of their ELF experiments that were recently ended? Even if so, what competing technology is the Navy contemplating that will reliably contact our submarine fleet that has "gone deep" under many fathoms of RF-attenuating sea water? I am thinking of the site in the Upper Peninsula of Michigan and the increased reliance on TACAMO aircraft (at the time of the shutdown). I also didn't realize that amateur radio had similar "networks" that would need to be shut down. The infrastructure that is being wasted on Morse includes band segments that have, until recently, been reserved for its exclusive use. I am very glad to see that almost all CW segments now allow data modes (50-50.1 and 144-144.1 being the only exceptions). There is also the inclusion of keyer provisions in HF radios. It will be interesting to see what the marketplace does to code tapes and code keys. I don't think they will last long. While Morse supporters often point to treaties, the fact is that the US was one of the last countries to abandon the Morse requirement for an HF license. Other countries began dropping that requirement many years earlier, while still claiming to be in compliance with their treaty obligations. How do you explain that? To me, it sounds like the FCC used the treaties as a pretext to keep the code requirement in order to placate the ARRL and the Morse zealots. Looked pretty coherent to me, but for your benefit, I'll dissect it in detail: "If you are saying that someone *else* should have developed these technologies ..." In other words, amateur radio has failed to meet some standard of technology development. Other people were somehow "wasting" their time doing other things. "... (other than you, of course) ..." What have you done to make amateur radio a better place? Have you written your Congressman? Petitioned the FCC? Worked in the communications engineering and technology field? Developed amateur radio software and hardware solutions? You seem to be knowledgeable on many technical subjects, including the history of that technology over many decades. Did you try to change things, or are you asserting that you did not have the skills or abilities to help do so, even working with others over many decades? I have worked in the electronics industry. I have made my views clear to any and all who had an interest in the subject. I made those views as clear then as I have done in this newsgroup. "... and since they haven't, then someone *must* be blamed, ..." I was implying that you were seeking scapegoats, as it is easier to blame others than look in the mirror. "... well, you can't really dictate how the world should turn out without taking an active role to help make it that way." In other words, Lead, Follow, or Get Out of the Way. "Sidewalk Superintendents" have very little influence on society. What is your choice? Also, some people seem to confuse actual solutions to problems (whether in amateur radio, or on the newsgroups) with a contest over who can become the most "outraged."
