They get away with that chit because few have professional programming experience here, indeed, 2nd or 3rd year software engineering students would even be able to "pull their covers." If the ear can tell the difference between a di and a dah, the computer sure as heck will not be fooled! This would only require that polymorphic coding be used in the software (self-adapting to such changes which can be deduced and "programmed for") and adaptive timing (comparing lengths of key-ons (di to dah) and constantly adapting for changes--only caring for the fact that a di is consistently shorter than a dah.) While this might be an interesting enough project for a 2nd to 3rd year college student, most upper division students would be required to have skills capable of solving much more complex problems involving algorithms with magnitudes of greater complexity! Any software engineer who possesses a bachelors degree will support this, even if they know NOTHING about amateur radio and ONLY that there will ALWAYS be a difference in length between a di and a dah and these length differences are (or may be) of a constantly variable nature. John, some years ago IN HERE I described what a Pro Programmer did as an "intellectual exercise" for himself. Perhaps 15 years ago or more; I let this acquaintence borrow my then-new Icom R-70 receiver for an "on-air test" using a simple audio filter and detector and TTL interface (which I tossed together at home) for a then-very-speedy 40 MHz clock PC. :-) This acquaintence was intrigued by the problem of deciphering variable-length anything and was vaguely related to his day job in setting up human interfaces for computers. It DID use "adaptive timing" although I don't recall those exact buzzwords. It DID adapt to both word rate, character spacing, and changes in ratio of dits v. dahs. It DID work, even on the ham bands (even then the primary source of morse code). It was programmed in C, not the C++ common to today. Assembler subroutines were short and the "housekeeping" sort used in other programming tasks with an 80x86 processor. [the later derivatives culminating in the now-common 'Pentium' instruction set) weren't around yet] I am "not at home" with C and am stuck on Fortran (77 variety as used in MS FORTRN 5.1 which MS dropped some years ago...and will no longer work in Windows XP at the DOS level). I don't pretend to be a whiz at programming but am fairly proficient with Fortran as a high-level language. [hey, I'm after number-crunching, not "art" in programming...results quickly obtained without going into arguments over how to do it with whatever is the source code a la mode...:-)] As far as I know, he never tried to market the program, not even add the ruffles and flourishes of some fancy interface screen, just a common (DOS Level) instruction menu, nothing fancy. It worked and he satisfied himself. I saw the source code and wanted a copy (never got one) so that I could experiment with it, write it in Fortran or even convert it to the Apple ][+ that was used once in a while. There just isn't any market (one that makes lots of money) for it now, hardly one back then. If you doubt me, call up a college and ask to speak to a instructor in software engineering ... don't take my word for it. They will NOT do that, John. Trust me. Their 'arguments' center around some cheapie box from MFJ or whatever, the kind using old, classic, FREE routines adapted to a particular microprocessor. I have yet to see ONE argument that bothers to take on the GUTS of such a reader...the dynamic adaptation to dit v. dah ratios, word rate, and (sure has hell) what to do about transient impulses that make their way into the incoming storage register. But, take this bunch of ancient key tappers as any type of software/algorithm experts? YOU HAVE TO BE KIDDING ME!!! Tsk, John, the Morsemen will be mighty put-out by such words. Their ability in morse and subsequent "extra" status (as amateurs) make them Masters of Radio! They cannot be argued with, only admired for the Mighty Achievements (including much paper with certificates suitable for framing). Ned Lud would be proud of them and their fight on the side of deus ex machina. :-) LA |

IMO the perfect fist sounds like computer generated CW. And it's the easiest to copy. All those so called 'unique fists' can be copied but it's like trying to understand someone from Brooklyn (or Texas)... ;) Well, there was some debate about this a few years back. It centered around a couple of things; 1) being a lack of an actual definition of Morse Code in Title 47, and 2) the desire of several of the Pro-Code Test folks to claim that a method of TEACHING Morse Code should be used as a Morse Code Exam, i.e., the Farnsworth Code. "Bang on" as the Brits say, Brian. BTW, it took the FCC years to finally update Part 97 from its previously OBSOLETE CCITT document reference to the 'proper' ITU-T document. Even then the proper document, like the old CCITT one, describes a COMMERCIAL telegram protocol, not an amateur one. Morse Code had previously been defined with specific dot, dash, and space interval ratios. Exams were then defined as Morse Code sent at rates of 20, 13, and 5 WPM. Today, they use the Teaching Method of Farnsworth Code, where the dot, dash, and interval can be anything desired, and character speeds of 13 to 15 WPM for a 5 WPM exam. That's fine for learning the code as Part 97 doesn't address any particular method, nor does it advocate any particular vendor such as W5YI or ARRL. Yet Part 97 still, even to this day, requires a Morse Code Exam (Farnsworth isn't mentioned) at a Morse Code Rate of 5 WPM. Lengthening the space interval isn't addressed as a way to get 13 to 15 WPM character speeds down to 5 WPM word rate. But hey, Part 97 is only a suggestion, right? A DEFINITON of WORD RATE is NOT DIRECTLY STATED in Part 97! Perhaps two sentences could have been included to SET or FIX the word rate...but the FCC never included that. When that was 'discussed' in here by the morse mavens, they all pointed to Paris with an "everybody 'knows' that" kind of attitude. And none of that matters now, anyway. THANK GOD! Miracles can happen. :-) Anyhow, the Pro-Code Exam folks were all over the notion that code was an individual thing and that each person's code sounded like "speech" to them because of all of the little and big imperfections, and sometimes the big imperfections were deliberate. I was chided for suggesting that manually sent code should be formed as precisely as one could make it, which sparked another debate. Apparently, humans trying to send perfect code shouldn't be a goal in amateur radio, even if unachievable. Which took us full circle to the humans emulating modems of the original invention of Sammy Morse, the code paper tape with dashes and longer dashes scribed on them. Sam's original "code" was all NUMBERS. That's what was used in the first US telegram company (Washington DC to Baltimore MD, 1844). Five-number code groups representing "common" phrases of the 1800s. And, it was done with paper tape with an ink pen driven by an electromagnet. Sam's financial angel, Al Vail, came up with the first true telegraphic code to represent letters and punctuation as well as just numbers. Sam was running out of numbers in his "code dictionary" and didn't have enough (or maybe patience) and the original morse code was NOT speedy...although it really, really outpaced the common rider-horse courier system for "overnight delivery" of that time. :-) Oh, well, it was a nice walk in the park. The PCTA folks arguments were as imperfect as the code they send. Tsk, tsk, Brian. By their own admission, *all* PCTA send Perfect Code! Much, much faster than 'we' can realize. :-) But, in retrospect, all the PCTA had for "reasons" of retention of the code test amounted to mental conditioning (brainwashing) over years and years of League emphasis on that mode. They were subconsciously parroting all of it. PCTA will NEVER, ever admit to ANY mental conditioning. To them amateur radio was all about radiotelegraphy. Before the turn of the new millennium, every other radio service had DROPPED OOK CW or never considered it when that radio service was created. Morsemanship is alive (and on life support) ONLY in amateur radio today. I say "only" because a few olde-tymers in other radio services MIGHT be still using morsemanship but that is NOT what is the MAJOR MODE of communications. Miccolis will jump in here and say I am "wrong" or "mistaken" (as is his usual ranting) but it is TRUE. Except for the die-hard (Bruce Willis wannabes?) morsemen in ham radio, morse code is DYING if not dead. THEY are the zombies, the "walking dead" who strut around pretending to be "champion ops in radio." Yes, "champion" in the time-frame of the 1930s. This is 2007, not 70 years ago. |

Yes ... he does. I made an OBSERVATION, Carl. Looking at www.nocode.org every day for a week after the 15 Dec 06 FCC announcement. It wasn't a week after the Public Notice, but a couple of days, before it was posted to the NCI website (and a link to the Report and Order was posted within 24 hours of its release). Then why didn't it appear that soon on the "NCI website?" One that us earthpeople could read? The ARRL was posting about it the same day! Let's face it. www.nocode.org has been QUIET on everything concerning the no-code-test NPRM. All that's been there for months has been a couple of notices about "officials" of NCI. Whoop-de-do. [it was like walking through a research library with nobody in it...] Suddenly, comes "word" from the "Chief" of NCI on "important news!" Allegedly "immediately" (more or less) "reported." I was on Maui for 10 days on a combination of business and vacation, but modern technology (my EVDO card) alllowed me to access the internet wirelessly from my notebook :-) Wow! High-tech! insert a Robesin hyena-guffaw here You should have remarked about a fancy hotel with Internet connections in every room or something. You don't have a direct satellite telephone? [Iridium is up and working, ain't it?] By golly, Carl, looks like you "joined the 'other side.'" What with the extra callsign and running (well, trying to) for office, and all the IEEE Standards committee work, you appear to be Greater than us ordinary earthpeople. It's rather obvious to most readers that Heil has had a deep personality conflict with me in here, by all indications a deep, antagonistic attitude wherein he keeps on finding "fault" with everything I say...and has been doing so for years. Now you are doing the same thing. Is that what Managers' Charm School taught you? Well, what I've been saying for years has come to pass. Give someone rank-status-privilege and they become "better" than ordinary folk. Gosh, maybe I should mention we were in Cabo for a shoot. [film, that is] Shoot, forgot all about it...:-) LA |

Like AM? -- The invention of the motorcycle did not make the bicycle obsolete. The invention of the car did not make walking obsolete. Power boats did not make all sailboats obsolete, although many sailboats were replaced by power boats. People still *run* marathons, even though they'd go a lot faster with a lot less effort if roller skates were used. AM did not become obsolete when SSB was invented. Morse Code did not become obsolete when voice and RTTY were invented. There will still be people who CHOOSE to use Morse if it's presented to them as fun and they're allowed to make the choice without intimidation (and without berating them) And if there's available spectrum and other Morse Code operators. And if there isn't it will be because not enough people are interested in using that mode. (I'm not trying to encourage its demise, just stating the evolutionary reality.) That's simply a restating of what I meant by "other Morse Code operators". But that's not the only thing needed. Regulations can be written that make it harder to use some well-established modes. For example, look what happened to plain old AM 'phone. Before the 1983-84 power rules change, hams could run up to 1000 watts input on AM. With a plate- or collector-modulated Class C legal-limit final, that meant up to 750 watts or so of carrier output. With advanced modes, even higher outputs could be obtained at 1000 watts input. But then the rules changed from 1000W DC input to 1500W peak output. Which effectively lowered the AM power limit by 50% or more. AM'ers asked that there be the option of using either system - 1000 W DC input *or* 1500 W peak output - but FCC said no. Except for a few people who learned Morse Code elsewhere, most would-be hams don't have any prior Morse Code skill. True ... The code test acts as a sort of Great Equalizer, Absurd ... Not at all. ALL that a code test does is indicate that you can copy Morse at some specified speed. Nothing more, nothing less. IMHO, that's a rather shortsighted view. Consider this statement: ALL that a written test does is indicate that you can pick out at least the minimum required number of correct multiple-choice answers in a test where all of the questions and answers are freely available beforehand. Nothing more, nothing less. The focus on the nature of the test (multiple choice) and memorization is specious and contrived to depricate the test. You're missing the point. The statement you made about the code test and the statement I made about the written tests are essentially identical. That's the point I was making. The US amateur written exams have been exclusively multiple-choice for over 40 years. That's not going to change. I'm beginning study for a private pilot's license ... and the written test for that is multiple choice, too. Does the FAA publish all of the questions and answers that can appear on the tests, complete with the correct answers pointed out? Can you take practice exams online for free? What score is needed to pass? Do you see experienced aviation folks saying the pilot's license exams are too technical, and need to be simplified? In the aviation field there doesn't seem to be a group of old-timers who bemoan the nature of the current test and denigrate newbies - in fact, I see AOPA and everyone I've encountered doing their best to encourage newcomers because they recognize that the future of general aviation depends on it. There is a big difference between pointing out deficiencies in license tests and methods and denigrating newcomers. I do the former, not the latter. Aviation is quite a bit different from amateur radio in many ways. For one thing, it's a lot more expensive, and potentially dangerous. A lot more judgement is needed for aviation, and what appears to be a minor error can turn into a disaster very easily. (Just look what happened to JFK Jr. because of an error in judgement). "There are old pilots, and there are bold pilots, but there are no old, bold pilots" In addition, as long as you don't cheat, FCC does not care how you get the right answers, nor which questions you get right or wrong. They don't care if you memorized, or if you guessed, or if you really understand the material. They also don't care if you have a Ph.D in EE, etc. - you get the same test. Yea ... what else did you expect. The point is that passing the written exams does not mean the person understands the material. Minimum entry requirements are just that. Doesn't matter where you start from. As long as you can pass the minimum requirements you get in. Hopefully you continue to learn and grow. Agreed - but what should those minimum requirements be? Does the current 35 question Technician written *really* test what a ham should know in order to operate 1500 watt output transmitters at (to use your excellent phrase) "meat cooking frequencies"? [snip to related material] The point I was making is that *passing the written tests* is/was a very different thing from passing the Morse Code tests, particularly if someone had some background in electricity or electronics. Which is much more likely today than someone having background in Morse Code. So??? That only goes to support the fact that Morse is essentially unimportant in today's real world. (not to say you can't still find it fun or that you shouldn't use it) Isn't amateur radio part of "today's real world"? Morse Code is part of amateur radio - a big part. I was talking night before last with Ed Hare - remember the 3 page study guide that he had for his novice test and compare that, as he does, to the 200+ pages of "Now You're Talking" - there has been NO "dumbing down" for entry into ham radio. How anyone could assert with honesty and a straight face that 200+ pages of material is "dumbed down" compared to 3 pages is something that simply is unfathomable. I have debunked W1RFI's "200 page" myth several times - including in person. I wish you'd been there for that one, Carl. Despite your assertions, I don't believe that Ed's assertions can be legitimately debunked. They can if someone has an open mind to look at the facts. [more snip for brevity] The "equalizer" idea is simply to point out that almost all hams who try to learn it start at the same place. That's not true of the written exams. Again - SO??? So some people don't like the idea of learning skills. And some people don't like the idea of learning something for amateur radio alone. Testing for licensure is not about "making folks work for it" or the liberal Democrat idea of "equalizing outcomes" (as opposed to equal OPPORTUNITY). There has always been equal opportunity to get a ham license. Show up, pass the tests, get the license. The equal opportunity is the opportunity to take the prescribed test - no matter WHERE you started from - and, if you pass the test, get a license. Testing should not be some sort of "social enginneering" exercise, but should ONLY involve the required demonstration of meeting the established minimum requirements for licensure. Any test is composed of at leasst two components: the material and the method. How well a test indicates the qualifications of the person tested depends on both. IMHO, the material of today's tests is roughly equivalent to that of the old tests, updated for changes in the rules and commonly-used technologies. But the *methods* used today are not comparable to the old methods. Which do you think is a better test of how well a person knows technical material: Method A: The general areas of the test are announced by means of typical problems, shown in a manner different from the actual test format. or Method B: The exact questions and answers that may appear on the test are shown in a manner identical to the actual test format. 73 de Jim, N2EY |
