Klystron wrote: Ultimately, we need to treat these various modes as methods of sending text - no more and no less. Two methods that send the same text are competing modes, regardless of whether keyboards, a telephone keypad or a telegraph key is used to send it. A method that sends those blocks of text faster and with fewer errors is better. A slower, more error prone method is inferior. Not all encoding schemes are equal. Some, like ASCII, encode the entire alphabet, including upper and lower case. Others, like ISO-Latin-1, can encode even more characters. In general, the more inclusive encoding method is better. An encoding scheme that is easily adapted to error correction (parity, automatic re-send, etc.) is also considered better. I hope you'll pardon me when I ask "Which deity spoke to you and laid down those particular points of Absolute Truth?". What's all this "We need to" and "no more and no less" and "xxx is better" and "yyy is inferior" and "... is also considered better"? If you're willing to state those as _your_ personal opinions of the basis on which two partially-competing methods of encoding and communicating _should_ be compared (and that no other criteria need apply), I have no objection at all. I do, however, object in principle to the idea that these are the highest (or only) criteria, or that they're somehow sacred. And, I also object to the idea (which I think is implied by the tone of your other messages - please correct me if I'm wrong) that the choice of communication methods is somehow exclusive... that the fact that a method which is superior (by your criteria, perhaps) means that other methods that you find inferior should be wiped out or abandoned... or that people who prefer to use the other methods are somehow responsible for Holding Back The True Progress. My own perspective is that people may have *many* criteria for chosing a means of communication (by radio or otherwise). Bandwidth, or bandwidth*reliability is not the sole criterion that people use, in practice, nor do I think there's any reason that it should be. Life is full of tradeoffs between different criteria - information bandwidth per Hz of spectrum, robustness of encoding, suitability for multi-point communication, resistance to different sorts of interference, cost of equipment, availability of equipment, and so forth. I communicate with my wife by voice, by email, by telephone, by scribbling half-illegible notes on scraps of paper, and by bringing home flowers... different methods, for different types of information- passing under varying conditions. In commercial communications and public-safety, bandwidth (or payload) and reliability and cost all play a big factor. In military communications, reliability and security seem big, bandwidth is important, and cost (of equipment at least) tends to take a back seat. Ham radio is a much more diverse motivation-space. Some people optimize their operations as for public safety and commercial (the EMCOM folks), others for "most distance per watt" or "per dollar spent on the radio" (QRP folks, homebrewers, and other experimenters), others for portability, others for plain ordinary fun (according to their own definition of fun... for some folks, using single-frequency crystal-oscillator transmitters is just what gets their rocks off :-) There's plenty of room in ham radio for different modes of operation. Saying that we all *have* to abandon Morse (or SSB, or voice, or AM, or...) and strap computers to all of our rigs, in order to encourage experimentation and use with newer modes, is really missing the point... it's implicitly denying a large percentage of hams the right to explore those aspects of ham radio that *they* find interesting and worthwhile. If we were all being paid to do all of this stuff, then the people paying us would perhaps have the right to set our agendas. We aren't (and by the rules of the game, cannot be... at least, not here in the US) and so we get to set our own priorities, operating-mode and otherwise. [And, for the record - I operate CW only rarely, and have enjoyed experimenting with packet and the newer digital modes quite a bit.] -- Dave Platt AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
