And if your CW rig "Chirps" it drives a DSP notch filter NUTS.

Why hang on to an obsolete technology on the EXAM for those who choose not to participate in the obsolete mode?

Jim Well, that sounds like a good deal (eliminate the cw only bands) for the no-codes, but it would end up a very *good* deal for the cw enthusiasts. Believe me, ssb would get clobbered from one end to the other by cw stations simply because of the wide spectrum that ssb occupies (compared to cw, that is). I have a feeling that if the cw bands were eliminated, a lot of phone folks would be screaming to bring them back. I'm not sure, but based upon my 75 watts being able to cut through a kilowatt station trying to clobber me and another station ..... both of us maintained a solid qso for half an hour at 35 to 45 words per minute cw whilst Mike, W2OY, was trying to jam us with a kilowatt of am. Didn't work then and I doubt it would work now. You're talking a 6 kHz wide am signal vs cw signals needing only a couple hundred of Hertz. You're talking at least a 14 dB or so advantage for the cw based upon bandwidth of the receiver. For the protection of the phone stations, I believe you will want to keep the cw bands intact. 73 from Rochester, NY Jim AA2QA |

wrote Hans, I know you think the best system would be to simply allow all authorized modes anywhere in the ham bands, by any licensed radio amateur. Now that's a STRETCH! I do believe that the FCC over-manages our allocations on most bands with their arbitrary slicing/dicing by mode/license class, without any obvious regard to "market forces". I'd like to see that cumbersome system replaced with a bandplanning model similar to many UHF/VHF bands where the users (that'd be guys like you and me) work out band plans which can be dynamically adjusted to meet our changing needs. The current US plan which allocates virtually 100% of our spectrum (less some minor slices near 5MHz and 219MHz) to narrowband CW, yet restricts every other mode regardless of popularity to smaller segments, is so backwards as to be spherical in its backwardness (backward from every possible viewing angle). 73, de Hans, K0HB |
wrote It would serve the useful purpose of making sure drivers had the basic skills required to drive a manual transmission car. There currently is no such test, but drivers who decide to use manual transmissions seem to learn that skill without a government test. Similarly if there is no Morse skill test, hams who decide to use that mode will take it upon themselves to learn that skill without the need for government testing. That complexity would benefit from some rules changes. Like a protected space for good old Morse Code. Morse code currently enjoys free access to essentially every Hz of amateur spectrum. Since CW is your (and my) favorite mode, that's what Martha Stewart might call "a good thing®" Would you support removal of that free access in exchange for "protected space" pro-rated by bandwidth relative to "protected space" for other popular modes? For example, a good fast CW signal might require "protection" for 150Hz and a properly operated SSB station might require "protection" for 2400Hz. Based on that ratio and your notion of "protected space" for each mode, for each 10KHz protected segment of CW spectrum, SSB operators should have a protected segment of 160KHz. Be careful what you wish for. 73, de Hans, K0HB |

In other words, if I speak "the" and make the association to the characters "t-h-e" the speech to text engine will always generate those characters when I speak that specific word--I could just as easily associate the spoken "the" with any other series of characters. Now, while you and I might not go to that trouble if we are fast typists, others who do not type will... those who are blind will... companies and corps will (and especially those employing disabled workers.) I have seen such libraries on the net for specific uses, such as programming, before. You most likely can download one for the speech engine in question... There are groups devoted to the blind who could easily supply you with them, I am sure... John Too many words in the English language that are pronounced the same but spelled differently for speech-to-text to work very well. Know-no, new-knew, see-sea, I-eye, nose-knows, sail-sale, to-two-too-tu tu, seem-seam, Sue-sue (name vs litigation), cheep-cheap, but-butt, ect., ect., ect. A speech-to-text probgram would have to be able to put the words into context. Probably doable to some level. |

Obviously they haven't actually listened to the parts of the ham bands where Morse Code is used. Model Ts aren't dead. Tailwheel airplanes aren't dead. Neither is CW. True enough. However, the driver's license test doesn't include hand- cranking Model T engines, nor does the airplane certificate test include 3-point landings in tailwheel airplanes. That's because the percentage of autos with handcranks is very small. So is the percentage of taildragger aircraft. Better example from the auto anology is manual gearboxes. There are significant numbers of new vehicles made every day which have manual gearboxes...but no state mandates driver testing on a manual gearbox to be able to drive one. Last statistics I saw were that 5% of new cars have manual transmissions. The other 95% sold today are automatics. Agreed, but in terms of total vehicles sold new each year in the US, that is several hundred thousand vehicles with stick shifts every year. Out of total sales in the millions. A tiny niche market. In fact, almost all cars can be ordered with an automatic transmission, but many *cannot* be ordered with a manual transmission. Morse Code accounts for a lot more than 5% of amateur radio HF/MF operation. The point still reverts to the exclusivity (i.e. stand-alone) testing for one mode and one mode only. No other mode, or subject area is so tested for an amateur license. Sure - because no other popular mode requires skills the average person does not already posess. Digital modes involve a certain skill level at typing. No one is tested to be sure they can operate at X wpm minimum speed. Additionally, what's wrong with a ham starting out at even 1 wpm on the air. Why must there be a minimum skill level. Two no-code techs can do that now on VHF. What's so special about HF vs VHF. Clearly the international community no longer sees the need for a morse skill test. How many hams would have to learn to talk in order to use voice modes? How many would have to learn to read and type to use keyboard modes? What's different about Morse Code is that most new hams today have to learn it just for amateur radio. And that, IMHO, is what bugs some folks so much. Probably so. But the percentage of ham stations on HF/MF using Morse Code is much, much higher. So? Nothing in the amateur rules requires anyone to every make a CW QSO, or, for that matter any contact using any mode at all. Exactly. Yet there are all sorts of test questions on things no ham is required to do. Why? Read again the following: The point still reverts to the exclusivity (i.e. stand-alone) testing for one mode and one mode only. No other mode, or subject area is so tested for an amateur license. The issue is and always has been the exclusive CW test in comparison to knowledge tested for any other modes. Without knowledge of those other modes, you can't get a license, even if all you want to do is to use Morse Code. Wrong....you can ignore or not learn about several specific subject areas...one or more modes of operation, etc. and still get a passing test grade. That depends entirely on what you consider a "subject area". If you define "subject area" as "questions about SSB voice", one could probably get all the questions about SSB voice wrong and still pass - *if* almost all of the others were answered correctly. But if you define "subject area" as "questions about voice modes", it's doubtful that one could get all the questions about voice modes wrong and still pass - even if almost all of the others were answered correctly. You assume ALL unknown questions would be answered wrong. Test taking 101 sez for ALL questions you don't know the answer to pick C. Doing so for 10 questions the test taker has no clue on is bound to net at least 2 or 3 correct answers. However, the remaining Morse Code test is probably going away soon. Just a matter of time. Probably. Why hang on to an obsolete technology on the EXAM for those who choose not to participate in the obsolete mode? "Obsolete"? Morse Code is the second most popular mode in HF amateur radio. Why are there written exams with questions on electronics for those who chose not to build their radios? No separate test exists for only the electronics. Nope - but try to pass the exam without electronics knowledge. It still isn't a separate exclusive test. Doesn't have to be. If you get all the other stuff (rules, regs, etc) 100%, you can miss a greater percentage of electronic questions then if it was a separate subject area test. But you can't miss all of them. But let's say you get 50% of those. Then you may end up passing the test if all the other stuff (rules/regs) is answered correctly. That isn't the case for the stand-alone morse test. The fact of the matter is that the current written tests involve a lot of subject areas, but not in a lot of depth. Morse Code testing involves one subject area, in somewhat more depth (although at 5 wpm, "depth" becomes somewhat questionable). It's like saying we have a manual-transmission test where the person must get the car in first gear and drive around an empty parking lot at 5 mph for one minute. And folks say that's too much to ask! And the IARU plus the WRC have stated it isn't required. They have left the choice to each individual administration...and that's where we are today in USA regs. The FCC has said it will end all morse testing (NPRM 05-235). Commentors are now and have been submitting their views for a month or more already. I haven't seen even ONE persuasive new argument to save code testing. All the procode test support argumennts are the same ones as before which the FCC has already reviewed and dismissed. The written is scored on an overall basis....not on a subject area stand-alone basis. Add some CW questions (similar in format to existing questions on the phonetic alphabet) to the tests then. What Canada has done solves that problem. Works for me. Moreover, there aren't special lanes on the road for Model Ts, nor are there special runways for tailwheel airplanes. But there are special lanes on some roads for cars only, high-occupancy vehicles only, etc. There are sidewalks and trails on which motor vehicles are banned. Why are there special segments of the band for CW. The only CW-only parts of the US ham bands are 50.0-50.1 MHz and 144.0-144.1 MHz. All other HF "CW" subbands are shared with digital/data modes. Correct. So would you support a reasonable set of Morse Code only subbands, Bill? Say, the bottom 10-15% of each HF ham band? I've said before that I have no problem with doing so. Within the USA, we could do so via ARRL voluntary bandplans without ever involving the FCC. Doing so might actually serve as a good incentive for some folks to learn and use morse. Makes far more sense to me than trying to keep the test itself. Cheers and I see my July 06 prediction becoming more of a possibility every day that passes now. Let's see...comments close sometime this fall...FCC takes six months to produce the R&O, coming out in early spring 2006...effective early summer 2006. You may be the winnah! The Pool is still ongoing. One thing I notice about FCC R&Os for the amateur service is that they almost never put changes into effect on the first of a month - always midmonth or something like that. We'll see.

The U.S. amateur radio frequency allocations show that MF-HF accounts for only 1 percent (rounding to integers) of total bandspace. Manual radiotelegraphy ("CW") is optional for ANY amateur class (except the old Novice) on ANY amateur band above 30 MHz...yet, without taking any "official poll" on it, it is obvious that "CW" is LESS than 1 percent of all amateur operation above 30 MHz. One percent of one percent gets to be a tiny value. The point still reverts to the exclusivity (i.e. stand-alone) testing for one mode and one mode only.

Clearly the international community no longer sees the need for a morse skill test. Anyone with a communications receiver or scanner can find out that FEW "average hams" speak or enunciate well. :-) There has NEVER been a speaking test for ANY U.S. amateur radio license examination. FEW "average persons" can operate TV modes, slow or fast scan, without the automatic easy-to-use features found on all consumer grade motion-picture cameras on the market now. I've not only used an RCA studio TV camera WITHOUT those features but checked alignment/scanning and the electronics of same. NO SUCH TV mode MANUAL TEST is done in U.S. amateur radio licensing. NO Manual Data mode TEST has ever been required in U.S. amateur radio licensing EVER, yet the FCC allocates Data modes coexisting with "CW" on almost all amateur bands. Manual radiotelegraphy "proficiency" testing has ALWAYS been in U.S. amateur radio licensing, through the three predecessor radio regulating agencies before the FCC was created. It is an "artifact" of testing that has never been removed due to opposition from just enough lobbying efforts to keep it in place. That it has "always been there" is absolutely NO valid reason to keep it. The international community, as represented by the IARU, came out over a year before WRC-03 on eliminating the code test for any license...at the option of each administration. The ARRL was opposed to elimination on through the last day of WRC-03 and now are ambivilent on that. We have yet to see the ARRL's comments on NPRM 05-143 in WT Docket 05-235. The ARRL's "compromise" plan is to retain the code test for Amateur Extra only. That is clearly a sop to their core membership who favor radiotelegraphy. However, at only 145 thousand members, the total ARRL membership is only about 20% of all individual licensed radio amateurs in the USA (721,481 as of 26 August 2005). How many hams would have to learn to talk in order to use voice modes? More than you would believe to listen to them on the air. :-) How many would have to learn to read and type to use keyboard modes? "Data" modes are not restricted to just keyboard input. What's different about Morse Code is that most new hams today have to learn it just for amateur radio. And that, IMHO, is what bugs some folks so much. Probably so. Not "probably." MOST CERTAINLY. 52 years ago when I operated my first big HF transmitter, "CW" skills were NOT required to send TTY and Voice on HF over "DX" paths. Of course that was in the military and the morsemen's argument is "that isn't amateur radio!" :-) Well, neither is broadcasting (called "Mass Media" radio services now), private land mobile radio service, aircraft radio service, or personal radio services...but all those services operate by the very same physical laws as does amateur radio service. Broadcasting, PLMRS, aircraft, personal radio services do NOT use "CW" mode nor do they test for that. Probably what REALLY "bugs" the NCTA is the terrible arrogance of the PCTA that morse code is the heart and soul of amateur radio, or words to that effect...plus, "only 'real' amateurs know code," a terribly elitist, exclusionary bit of bigotry that grew stronger with the so-called "incentive plan" licensing (lobbied for by the ARRL). snip But if you define "subject area" as "questions about voice modes", it's doubtful that one could get all the questions about voice modes wrong and still pass - even if almost all of the others were answered correctly.

NOT a question of "so many 'other' questions right/wrong," a matter of singular FAILURE. snip But you can't miss all of them. But let's say you get 50% of those. Then you may end up passing the test if all the other stuff (rules/regs) is answered correctly. That isn't the case for the stand-alone morse test. You said that before, I've said that before, lots of others have said that before, and the FCC says so in the regulations.

Morse code will be extremely valuable in coordinating communications to counter-attacking alien invaders; the will never understand morse code so they will be caught be surprise.
