N2EY:
that is all wet. Although an increase in bandwidth can be used to transmit more data, what we are discussing is the protocol of binary transmission in the form of video data and in an agreed upon structure over a roughly ~5K audio bandwidth--or--simply put, data throughput measured in bits (or bytes, or words (16 bits), or double-words (32), etc, per second. This all can be done with existing, common equipment modified to do so, and easily at rates of 56K, over the audio bandwidth of most transceivers (or with minor modifications of the transceivers audio circuits), with most remain ignorant to the fact it is being done at all! If some hams want to jack around all the standards and methods which are already in place--screw with current terminology and "encode" all this to "ham words/terminology/technology" with the hope of obfuscating the facts and making it appear that the hams have invented the internet, have at it! I am sure the digital youngsters will find this a strong draw to amateur radio. The technology has been out there for over a decade, in everyday use for 5 years or better, and now is used widely in industry for security monitoring, etc. You can buy it off the shelf... The real experimenters have now moved on and use nothing less than 100MBS+ nic cards and wireless wans interfaced to transceivers through computers over spread spectrum... which some one will point out is a violation of FCC regs for amateur radio bands. It will probably be another 10 years before hams "invent" this new gig. Possibly longer if they sit around and argue whether it can be done or not... ROFLOL John wrote in message oups.com... John Smith wrote: N2EY: Most of that is incorrect. Most of what? First you use "on the fly" encryption/decryption/"data compaction" and have it occurring in "real time." This has the effect of being "transparent" and the user is not even aware that it is going on. That's what "Convert the pictures and video into highly-compressed digital formats for transmission." means, John. Whether it's done in "real time" is just a detail. Next, forget the sn/noise ratio other than it has to acceptable for transmission of understandable communication (however, this is required no matter what the form of data--i.e., voice, ssb, cw, etc) Signal-to-noise is an integral part of Shannon's thereom. It cannot simply be "forgotten". Next, listen to digital signal occupying audio bandwidth (it is audio bandwidth that is of concern here, NOT rf bandwidth, No, that's not correct. The discussion is about transmitting pictures and video on the amateur HF/MF bands. RF bandwidth is a very important thing there. except with the possibility of fm and how you implement the data compression and transmission, i.e., just make it fit the existing rf bandwidth and NO changes are needed--however, larger rf bandwidth will ALWAYS result in a drastic increase in transmission speed and wideband fm can easily offer itself to 1MBS and faster) a digital signal can be treated just like a analog signal if desired, the use of CRC checksums and error checking of the data is just more intense under these circumstances and there is NO standard established for this--so you MUST be able to make and use your own custom hardware and software. To avoid this, just grab off the shelf digital hardware/software. And the simplest way for hams to do that at HF/MF is to use an SSB transceiver and a computer with a sound card. But that's not the only issue. Next, for every patented form of audio video protocols there are FREE forms, usually the free ones are more acceptable, efficient and suitable to ones needs, an example: Use ogg vobis compression of audio as opposed to mp3 --in video-- Use xvid as opposed to divx 4-5 And make sure the folks at the other end are similarly equipped. However, any of this requires a sound and current education and knowledge of the state of technology--and something which is obviously lacking here. Yes, John, your lack of a sound and current education about amateur HF/MF communications is quite evident. Good to see you admitting it. There's also the issue of FCC regulations. Of course those regulations can be changed, and there are several proposals in development or before the FCC to change them. But until they are changed, amateurs will be constrained by the current rules, such as the 300 baud limitation on HF. The vast majority of hams are not going to break those rules, regardless of the available technology or their education. The question raised by KB3EIA and N8UZE remains: How can video be sent in a 2.5 kHz RF bandwidth on the amateur HF bands? I've answered that question in a theoretical way. I don't think you even understand the question and all its implications, John. wrote in message oups.com... Mike Coslo wrote: Dave Heil wrote: wrote: How we be gonna scale those pictures and live video to fit into 2.5 KHz? Two steps: 1) Convert the pictures and video into highly-compressed digital formats for transmission. 2) Use different modes/modulations/protocols Shannon's Theorem tells us that we can get very high data rates through very narrow bandwidths *if* we have adequate signal-to-noise ratio. Note that "noise" takes many forms, not just the thermal noise we're used to. For example, PSK has an advantage over OOK when dealing with thermal noise. But when dealing with other types of noise, OOK can have an advantage. It all depends on the transmission medium. What works on a telephone line may not work on an HF path of the same apparent bandwidth. I thought that we were going to be able to send live video and digital images on HF? You can do that now - just need enough S/N. Simply by hooking our computers to our rigs via the proper interfaces. And software. Now it seems that the *idea* is that we are going to use DRM, and we're going to need to get more spectrum in which to use. There are all sorts of solutions. But there's a world of difference between people talking theory and actual application. Most of all, some folks confuse the journey and the destination. Does complex and newer equal better? Sometimes. Not always. Is analog simpler than digital? Sometimes! Does having a computer that attaches to the Internet make a person a digital expert? Some folks think so! I don't. And besides - "digital expert" doesn't mean someone knows much about radio. I ask for enlightenment, I get invective. Are you surprised? Appears to be what there is to offer. Now consider how effective such a person would be trying to sell amateur radio - with or without a code test. 73 de Jim, N2EY |

Most at VHF to SHF+ freqs have no license and don't want one--I am speaking HF here. Most only want to be able to speak to others in new zealand, australia, malaysia, indo-asia, britian, etc... Something which they bypass vhf+ for, those who are not freebanders use the internet there and chat internationally... John "Dee Flint" wrote in message ... "John Smith" wrote in message ... KXHB: Go ask the college and high school students in the EE fields why they do not obtain amateur licenses. I have asked, it is the code which they cite at least 90% of the time. However, you guys don't care, and will go on speaking like that is not true. Put your butt in a car, drive over to your local college and have a chat with an electronics engineer professor there and the students--then perhaps you will realize we who know are looking at you like some crazed manic reciting a ridiculous mantra about code not being a hindrance and the real reason amateur radio is dying... John Since all the "new action" is VHF and higher and that doesn't require a code license, code should be no detriment. Or is some one fibbing to them either directly or by omission so that they do not know about the codeless Technician license. Dee D. Flint, N8UZE |

Frankly I am surprised you are so offended over his "derogatory remarks", you all seem so asleep to the real world that short of striking you over the head with a two-by-four you will remain in this dream-like state. Positive is not always good, except to "new agers" studying mysticism and crystals, and I have no time for silliness... If offended by reality one can always change reality or change themselves--I have always found the latter more productive. He (Len) battles a whole klick of you which are functioning like a damn support group--and you don't let little things like reality, "real world", sanity and facts get in your way. You all begin your chants of known mantras and chase the light-weights away! You all exist in an echo chamber using the echo of your own words as "valid arguments", or to site "majority agreements." Get real, to any cutting edge people, they feel like they have entered the twilight zone when here!

Len: I finally figured out why they truly hate you here! You are getting there, sort of...it's actually deeper than that. You have made a statement that cw is ridiculous and protested by never getting an amateur license--now there are tens of thousands or even hundreds of thousands who have joined you--I see them everyday--they refuse to get a license because of the code... See the classical reducto ad absurdum response of Hans Brakob. :-) Most of the commentary by the "regulars" (nearly all Pro-Code Test Advocates (PCTA) amateur extras is predictable and worded in the classical "league-speak" that has washed their brains. They are few and NONE of the are, in any way, "representative" of the "amateur community" despite what they exclaim. NONE of them (Brakob included) accept any contrary commentary and each feels that their tight clique must remain sound...regardless... The "reply" that is a classic reduction-to-the-absurd of Brakob is just one style of highly-negative response to "outsiders" (those who do not think as the clique does). Heil stresses the "personal involvement" as if he is a moral arbiter of all but that is his only remaining retort and the glass of the retort is cracked. Miccolis is firmly entrenched into a mindset of amateur radio of days prior to his existance...a condition that may have been caused by way too much rereading of ancient copies of QST enshrined in his basement. Kelly is basically a blustering Philly Tuff Guy who don' take nuttin from nobody! Flint is one of the truer products of league pre-conditioning ("brainwashed" in familiar terms) but, to her credit, defends the Newington barricades vigorously. Robeson is the emotional wreckage of an exploded loose cannon littering the imaginary battlefield. Jeswald ("Dan/W4NTI" who apparently changed his surname) acts the southern-fried good-ole-boy and is little more than a braggart, nasty when drunk. There have been others, but the above coterie (perhaps 'cotillion' of ancient debutantes/dilettants) makes up the "representative" body in here. Each is a Special Interest Group of One. They purport to be the "Voice of Amateur Radio" yet all speak solely for their own particular desires and each holds to an intimation that they are the proper role model for others. ["all must do as they did to be as good as they"] Thousands of others interested in radio have come on various scenes before I did. THEY are the ones that pushed forward for the no-code-test Technician Class license creation. Such was created. The God-fearing morsemen all sounded the Hue and Cry with the "death of amateur radio (without the beloved code test to show the "dedication and committment to the amateur community")" on their lips. At present, the "lesser-class" licensees in U.S. amateur radio (Technicians) amount to 48.43% of all individual licenses as of 2 Jul 05. That was achieved in a scant 14 years. Had the Technician classes not existed, U.S. amateur radio licensees would have shrunk to less than 60% of its current size now. The intrinsic appeal of morse code ("try it you'll like it!") is nebulous, more vapor than substance. Amateur radio - as the olde-fahrts knew it - IS beginning to shrink. Without change, it WILL die out...but after the olde- fahrts do. The olde-fahrts are Holding Back The Dawn, fearing the sunshine of new ideas like vampires trembling at sunrise. At best, their "new ideas" exist in the "new band" trials at 600 meters...the old 500 KHz maritime distress and safety frequency that was. "CW" of course. All is morsemanship in the ARS (Archaic Radiotelegraph Society)...that "cutting edge mode" exemplifying "keeping up with the state of the art." "Bang the Carrier Slowly" would be an alternate title. ... that is why they hate you, you were a man before your time my friend! Not really. I disturb their self-image of expertise and elitism. I challenge their brags with some experience in HF and VHF and UHF and microwaves communications. That is the breaking of illusions they harbor, a sort of mental Krystalnacht of theirs and they feel persecuted, seek vengence and retribution for disturbing their fantasies of glory, honor, and nobility. [I pop their balloons] Others have been the pioneers of NCTA-ism. They were before me. They deserve the credit, not me. I'm simply outspoken and on the other side of them. They can't handle it...the league hasn't instructed them on how to handle such humans...they revert to middle school taunts, acting like middle-aged children. Tsk, tsk. :-) And, your protest is being voiced by a strong majority today. The PCTA hear not. The olde-fahrts holding back the dawn hear not. They will resist until the last code key is pried from their cold, dead fingers. They WERE "operators." |

Dee:
Developing a sense of humor and being able to have "fun" poked at oneself is viewed as desirable by some, indeed, those who take themselves far too seriously are an offence to me--whether they realize it or not, sometimes I am polite and don't point that out (rarely though. grin) As a side note, I am running MS Agent (Microsoft Agent--all components of this are either already in windows xp or downloadable for windows 95 and up, a friend in france supplied me with the french engine) text-to-speech and speech-to-text engines. I find with the french library of phonics I am able to chat with french speakers to a remarkably good degree of success, and I am the only one which needs to run the software, doing ALL translation on my end solely! (but makes "me" sound rather "robotic" when I "speak" french. grin A transceiver, computer/"sound card" and the free software is all which is necessary to begin using/experimenting (the speech phonic library(s) may have to be purchased for some languages--I am unclear on this, and an ability to a software programmer or access to a programmer is highly suggested.) I am beginning to look upon this as Capt. Kirk's "universal translator", when the aliens finally show up (and can supply me with a proper speech engine) I plan on being among the first to verbally greet them! grin Anyway, this is an area where experimenters should come. As, I know of only a handful of techies experimenting here and of no "successful" commercial products on the market. If there exists any of a competitive nature, here are the waters to weigh anchor and hold battle! John Video, at this point, is pretty much "ho-hum stuff." John "Dee Flint" wrote in message ...
