Mike,
Thanks for your comments - mine are below: On Mon, 05 Jan 2004 15:52:25 -0500, Mike Coslo wrote: Leo wrote: Very insightful, Mike! Especially the use of digital voice, and the transmission of images on 144 MHz repeaters. That does make sense! I'm surprised that digital voice in particular is not being played with much today on HF - that may well be the future of radio right there, based on the direction the commercial broadcasters are headed. I thought I replied to this post, but maybe not. I think that Digital voice takes up more BW than SSB, so there will probably be a wait for future developments. True, but maybe one of the roles of the 'new' amateur service would be to serve as a testbed for new technologies like this one. With all of the new licensees concentrating on playing around with it, and no old low-tech stuff to impede them ![]() than in our current scenario. I would also expect to see much more emphasis on the convergence of the Internet with amateur radio - IRLP, e-mail servers, wireless messaging and similar concepts, for example. Handheld radios would probably have many cellular-like features - text messaging and built-in cameras, for example. Probably. Ham/Internet functions would probably be a lot better than what they are now, and people like me, that don't think that the Internat is Ham radio would not have time to form their biases. Make that one 'us' - I don't consider any Internet-linked radio system to be a 'real' radio - more like a telephone, at best. But, you are absolutely correct, this bias of ours would not exist at all! Folks who grew up in the age of the 'Net may see the new Radio service as an extension of it. I am positive that CW would be rediscovered and resurrected by those who wished to experiment with a historic signalling method used in the golden days of long distance communication. Special interest groups would spring up, as they would for RTTY, SITOR and other interesting though antiquated protocols. I agree about the CW. That would probably come about as a minimalist thing, kind of like QRP is now, but with extremely simple equipment. I don't think that RTTY would come about. I think amateurs got started on RTTY after getting surplus writers. There probably wouldn't be many of them left today. And the encoding scheme wouldn't likely be adopted I was thinking more of those folks who had been monitoring some of the commercial RTTY utility broadcasts (like the Canadian Army's aviation forecasts out of Halifax, NS at a blistering 75 Baud, for example), and who would want to try it out for themselves. With a PC, encoding schemes are relatively simple to create and play around with - maybe some nut would do it just to see if they could? (Maybe even this nut..... ![]() However, truly outmoded forms of communication common today would not exist at all, such as the repeater phone patch (in an era of cheap cellphones, who would even think up this one?) For emergency use, a similar interface to the public network would be provided, perhaps directly to a PSTN operator. No more personal phone calls, though!). Agreed. Without the legacy of all of the current AM, CW, SSB, RTTY etc. equipment from years gone by, the requirement to fully support these modes on the new bands would not exist. What modes would be popular in equipment produced to meet the demands of the amateur service? In addition to standalone radios (at least for handheld service anyway), would we see black boxes designed to interface to PC and antenna, with software to run all manner of digital communication (high speed modem, digital voice, image transmission, low-res full motion video, etc.)? I would also anticipate that, in the interest of ensuring compliance with regulations, that each commercial radio may be designed to automatically transmit a unique identifier over the air, which would allow authorities to trace back faulty, out-of-band or malicious operation to a particular unit. This feature could be coupled with a built-in GPS receiver, to further aid in localizing the radio if and when necessary. This may well raise privacy concerns, but it could be mandated as part of the operating licence, just as mandatory transmission of the operators' call sign at intervals is today. And, as we are assuming a brand new service, it would be relatively easy to do - with no older units to retrofit. What would happen with homebuilt equipment, though? hmmmm. not sure if I like that! Me either - concepts like this scare the heck out of me. But, the potential for some unsavoury character or terrorist to acquire a radio with the capability to communicate globally (and stealthily - pretty hard to find one, especially if it transmits on a random schedule!!) and use it for whatever nefarious purpose may prompt the government who created the 'new' amateur service to build this in right from the start. It's very technically possible, and cheap and practical if done en masse right from the beginning. (after all, who ever thought that an innocuous little computer in your car could be used to produce data to nail you in court over an accident?? Hmmmm. That wasn't in the Owners Manual....) Included as a discussion point......we'll see if anyone else shares this view / concern. With respect to testing, I would anticipate that the regulatory and operating etiquette sections would continue to exist in virtually their present form. Along with the addition of more Digital questions to the theoretical portion of the tests, we may well see questions on interconnection to the Internet, firewalling and network security. There may be a new test section on emergency traffic handling, radio net and message relay operations - this being the most likely premise that we would be able to convince anyone to hand over all of this valuable radio spectrum to us in the first place! And given the priority of national security in our post-9/11 world, there may be a mandate for the amateur service to link very closely with the various emergency management agencies, upon governmental request? I would envision a requirement for perhaps two different licence levels, though - one for the basic equipment operator, limited to perhaps 100 or 200 watts, commercially built and type-approved transmitting equipment only, not permitted to act as control operator of repeaters. A higher level licence would be granted upon passing more stringent testing on RF safety and high power operation, repeater commissioning, internetworking and advanced electronic theory, which would remove these restrictions. Either licence level would have full access to all bands and modes, with no restrictions other than those listed above. The licence levels are not intended to be incentive based, but to ensure competence and safety (both personal and public) when installing and operating multi-user automated-access, internetworked or high RF power output equipment. Of course, there is the remote possibility that a Usenet group dedicated to the endless (and animated!) discussion of whether RTTY testing should be discontinued might crop up - hopefully very remote ![]() HAR!! Yup - the seeds are already sown for "NORTTY International".....I can hear 'em growing from here! ![]() - mike KB3EIA - 73, Leo |
