Oh, my, some SPITE was carried over to homebrew on
Presidents Day just because "CW" was discussed. I am bringing it back to policy where it should go until the moderated newsgroup is open. Be aware that this thread in RRAH started with a simple question by another asking if FCC 06-178 would "eliminate the CW bands" [in amateur radio operation] That was answered. After that it segued into discussion of early (pre-1900) use of morse code then it was triggered into modern times by those who feel that "CW" MUST be given ten kinds of attention than anything else. Miccolis *HAD* to make noise in his usual manner there even though he was not involved. ================================================== =============== WAS in Newsgroup: rec.radio.amateur.homebrew From: Date: 19 Feb 2007 10:02:39 -0800 Local: Mon, Feb 19 2007 10:02 am Subject: CW Bands On Feb 18, 11:15?pm, " wrote: Ian White GM3SEK wrote on Sun, 18 Feb 2007 Actually, that depends on how you define "biggest". Whatever YOU have is 'always' biggest. Yes, we all know. :-) ? ?I first "fired up" on HF in February 1953, part of my being ? ?assigned to a US Army communications station in Tokyo. ? Incorrect quotation. I did not write those question marks. Other than that, a 20-page photo essay describing what was done over a three-year period is a free download: http://sujan.hallikainen.org/Broadca...s/My3Years.pdf On a dial-up connection that will take about 18 minutes and is about 6 MB in size. A station that was maintained by several hundred Army personnel. It was? Were you THERE? No, you were busy gestating at the time, hadn't emerged yet. Sorry, but I don't have a COMPLETE T.O.& E. (Table of Organization and Equipment) of the Battalion and can only approximate the number of personnel by direct visual observation being IN that battalion. That ? ?was a small 1 KW HF transmitter using TTY FSK. ?There were ? ?three dozen other transmitters there; six more would be ? ?added by 1955. ?NONE of the radio circuits of this 3rd ? ?largest Army station used any OOK CW mode of modulation. Incorrect quotation. I did not write those question marks. However, that was one station in one place. Yes, amazing deduction, Sherlock Miccolis! :-) The other stations of ACAN, the Army Command and Administrative Network (the acronym of that time) were at Ft. Detrick, MD, [WAR, the center point for this worldwide network], plus (to the circuits of ADA in ACAN) Anchorage, Alaska, Seattle, WA, San Francisco, CA (actually Davis, CA, outside of San Fran), Honolulu, Hawaii, Manila in the Phillippines, Okinawa, Pusan and Seoul, Korea, and Saigon, Vietnam. Once a month there was a test period of communications to Asmara, Eritrea to check predicted propagation from Asia into east Africa. Another free upload: http://sujan.hallikainen.org/Broadca...phabetSoup.pdf Shows a map of the radio circuits as they were about 1963 for ADA into an enlarged ACAN...the network having changed its name. There and on the Links section for US Army in Europe (USAEUR) private historical site is the full TTY message routing paths over the world. Note that the TTY message address preamble would use the "Rxxx" designator, NOT the originating or final receiving Army radio station callsign. ADA in Tokyo was "RUAP" and WAR at Ft. Detrick was "RUEP." It was not necessarily representative of all military radio communications at the time, nor of amateur radio communications, then or now. "Not necessarily representative of 'all military radio communications at the time?" Silly little man, this was a specific period of 1953 to 1956 when I was a PART of that operation, IN the US Army, a station that was under Central Command, US Army in Japan, supporting the Far East Command Headquarters then in Tokyo. I've not claimed otherwise. However, the photo essay manuscript was sent to Mr. James Brendage, a now-retired civilian engineer who was THERE and working IN that facility. Jim Brendage sent me in return supplementary material that was produced by that Signal Battalion after I left. That (digitzed) became the other document at Hal Hallikainen's site called "AlphabetSoup." I received other photos and documents from Jim Brendage and exchanged information about the late Walter Ross, an RCA (EASD, Van Nuys, CA) staff engineer (in my working group at RCA!) who had also worked at ADA as a civilian engineer before I was assigned there. Walt had seen some of the 600 color slides I had taken at ADA and didn't say they were incorrect or faulty. In addition to that, I've been in e-contact with a retired USAF MSgt who had worked at the new ADA transmitter site after 1963 and the USAF having been assigned responsibility there. We shared much info, with him interested in "how it was in the beginning" meaning the 1954 time that I helped move the trans- mitter site up to Kashiwa, Japan. Worse yet (for you) is that I've maintained e-contact with a licensed radio amateur (and licensed radio professional) now retired from the FAA who was assigned to the SAME battalion, SAME company, SAME duties at the ADA transmitter site but on another of the four operating teams. Gene can verify as to my accuracy in the photo essay. I've never claimed my military assignment involved amateur radio. At best, one radio circuit was available to the Tokyo MARS facility on a third-priority basis, RTTY only. MARS operations in Tokyo were divorced from the ACAN network administration some time in 1955. MARS does not, cannot operate IN USA amateur bands...it is under the directorate of the Department of Defense. However, technology-wise, a vacuum tube power amplifier stage for HF range operates the SAME for amateur or commercial applications now in 2007. The rule of thumb in tuning tube power amplifiers is the same now as it was a half century ago, "peak the grid and dip the plate." [referring to currents] ? ?In my subsequent career change after service into ? ?electronics design engineer I've never had a requirement ? ?to use OOK CW on radio. ? INCORRECT quotation. I did not write those question marks. Try not to selectively EDIT quotations. You have also never been a radio amateur. I've never claimed to be one. Nor a professional radio operator. INCORRECT. WRONG. MISTAKE. BULL****, little man. I have three old First Class Radiotelephone (Commercial) certificates with handwritten signatures of officials at various stations attesting to my professional services rendered. Those signatures were done and dated when that First 'Phone license was in force. Some of those are for broadcasting stations but an equal number are for corporations involved in private radio communications. One of the latter is by one of my partners in a private business...which may be a subject of a new Flame War by some self-styled amateur communications attornies. In several years of working at private corporations involved with Department of Defense radio and radio- related contracts, that First 'Phone was NOT necessary. DoD radio communications do not fall under FCC jurisdiction. The FCC is chartered by Congressional LAW to regulate USA *civil* communications. "Professional" work is that which is compensated for monetarily. [one gets MONEY for services renedered] I was paid money regularly and the IRS and Franchise Tax Board of California attesting to that. Until 2005 when my wife and I bought ? ?a new car having a keyless entry radio-on-a-chain-fob. ?That ? ?fob transmitter is OOK CW. ?But, its data rate is beyond ? ?human cognition, ANY human. Incorrect quotation AGAGIN! I did not write all those question marks that you apparently added. Of what relevance is that to amateur radio? The keyless entry transmitter uses OOK CW mode! Your favorite mode! They mode you are so inordinately proud of! The mode that enabled you to get an amateur extra class amateur radio license! Aren't you more upset personally that we bought a NEW car in 2005? And paid CA$H for it? :-) It's a nice white exterior Chevrolet Malibu MAXX, very comfortable, has taken us from California to Wisconsin and back, to Washington state and back. My wife used the car today and transmitted OOK CW without any radio license via that keyless entry transmitter! Maybe you'd like to inform the FCC about this "illegal use" of radio by the unlicensed-in-any-radio-activity? :-) ? ?I have nothing against telegraphic skills nor anyone using ? ?those for personal pleasure. ? Many of your statements elsewhere on Usenet contradict that. Awww, poor baby. Still have the Spite spiked high with adding all those question marks I never wrote? Yes, you are certainly upset by what I've said. However, in the light of ? ?advancement of the electronic arts, communications, radio, ? ?methods that ALL of us can share, I think there is an ? ?over-much emphasis by radio hobbyists on telegraphic arts. INCORRECT QUOTATIONS AGAIN! Oh, my, still sticking your question mark where it doesn't belong? IOW, it's OK with you if someone uses it, as long as they don't emphasize it. "IOW?" Is that a morsemen's union? Oh, you mean "In Other Words!" Oh, my, if I wanted to write "other words," I would have written OTHER WORDS. Did I write "other words?" No, I didn't. Why do you say I wrote "other words" when I didn't write other words? Why are sticking those question marks all over my quotes? ? ?Manual telegraphy IS a historic first but it has been ? ?supplanted in practical communications means at our ? ?disposal...on land, in the air, on the sea, and in space. Morse Code is also practical communications. So are blinking lights, semaphore flags, ship signal pennants, Boy Scout wig-wag flags, railroad lights, traffic lights (that show "go" and "stop"). Show us MODERN-DAY COMMUNICATIONS services STILL USING morse codes...OTHER than amateur radio. Can you find any? And it is widely used in amateur radio today. Not a quantitative statement. According to an ARRL poll, OOK CW is the SECOND-PLACE mode on amateur HF bands. It's an old poll. Maybe radio amateurs have suddenly taken up morsemanship and are busy, busy, busy dotting and dashing everywhere? How wonderful for you...you now have hopes for playmates on radio in the future! ? ?I think we should be looking FORWARD to the future, not ? ?back to the past. ?Others disagree. ?I leave it at that. What does "FORWARD to the future" really mean in that context? Try NOT using Knotts Berry Farm "railway station" automated sounder in their REPRODUCTION of an old- time rail station. Hardly an "authoritative source." Now you show us all a Non-Amateur radio service that regularly uses morse code mode for COMMUNICATIONS. TODAY. This year. NOT an exhibit or reproduction. A working service. Better yet...bring out your WIFE, as a "witness" to some inaccuracies I'm supposed to have stated. You DO have a wife, don't you? And one with an amateur radio license, right? Good lad, I knew you could... Tsk, Jimmie put two and two together and got ate... Chow, LA |

No, that's not true. Len just can't stand to see nice things written about Morse Code. Here's what *really* happened: Len made a lengthy post that contained comments on the US railroad system, landline telegraph communications, Knott's Berry Farm and other tourist attractions, stagecoaches, wives-and-families, Len's lack of use of Morse Code in military communications, 50plus years ago, Len's parents watching the lunar landings on TV, keyless auto security systems and more. I didn't see a single word from Len in his long posting about amateur radio homebrew. It also contained this personal policy statement from Len: "I have nothing against telegraphic skills nor anyone using those for personal pleasure. However, in the light of advancement of the electronic arts, communications, radio, methods that ALL of us can share, I think there is an over-much emphasis by radio hobbyists on telegraphic arts.

I think we should be looking FORWARD to the future, not back to the past. Others disagree. I leave it at that." Sure sounds like a policy discussion to me! Now there's nothing really wrong with a little thread drift and getting a bit off topic. So I replied with a post of my own, commenting on some of what Len wrote. Free speech and all that: http://groups.google.com/group/rec.r...e=source&hl=en But then Len got all upset and acted like a moderator: http://groups.google.com/group/rec.r...e=source&hl=en Sure looks like Len has a double standard about who can post to rrah and what they can post. It's OK for *him* to wander off topic and make policy and opinion statements there, but when someone rebuts his commentary, that's *not* OK with him. Textbook case of Len's double standard.

? ?Oh, my, some SPITE was carried over to homebrew on ? ?Presidents Day just because "CW" was discussed. ?I am ? ?bringing it back to policy where it should go until ? ?the moderated newsgroup is open. Len wants to be the moderator, IOW, FACTUAL ERROR! Tsk, tsk... ? ?Be aware that this thread in RRAH started with a simple ? ?question by another asking if FCC 06-178 would "eliminate ? ?the CW bands" [in amateur radio operation] ?That was ? ?answered. Buit it didn't end there. What is a "buit?" Or did you make another FACTUAL ERROR? ?After that it segued into discussion of early ? ?(pre-1900) use of morse code then it was triggered into ? ?modern times by those who feel that "CW" MUST be given ? ?ten kinds of attention than anything else. No, that's not true. FACTUAL ERROR. IT IS VERY TRUE...with or without the "?" additions YOU made to the quote. Here's what *really* happened: PERSON J MAKES ANOTHER FACTUAL ERROR... HERE is what happened, visible by anyone at RRAH: On Feb 12 'Julian814' asked about CW use in ham bands after 23 Feb 07. On the same date about an hour later Michael Black stated that this subject was not one for rec.radio.amateur.homebrew. 'Caveat Lector' made a comment next about 3 hours later. On 13 Feb, 'GKB', Scott, John Siegel all made comments. On 14 Feb, Geoffrey S. Mendelson made a comment from Israel. About 3 hours later 'Julian814' posts again, followed by Dee Flint two hours after that. On 15 Feb Ken Scarf made a comment. On 16 Feb Geoffrey Mendelson made another post and I replied to that (about 3 hours later) stating some difference of opinion on early telegraphy methods prior to 1900...based on information obtained from several sources, including the website of the descendents of Alfred Vail. On 17 Feb Ken Scarf made a short comment about modern day morse code use. On 18 Feb I replied to that and stated that the commentary between myself and Mendelson was about pre-1900 telegraphy. About 2 hours later, Ian White made a long post objecting to my comments about morse code being supplanted by other modes and used his father-in-law and wife as "witnesses." According to White, his father had taken his wife (and presumably the rest of her family) to Knotts Berry Farm near Anaheim, CA, where the father-in-law described an old railroad station telegram station with its sounder tapping out "eat chicken dinners" continually. Also on 18 Feb 'Highland Ham' made a short comment. In two posts that I made, 4 and 6 days after the first one, the SUBJECT was addressed in some detail. There was no overt expression of "dislike for 'CW'" by myself. Seven days after the first post in the thread, Miccolis just HAD to say something negative about my posting. :-) What he 'read' is stated as follows: Len made a lengthy post that contained comments on the US railroad system, landline telegraph communications, Knott's Berry Farm and other tourist attractions, stagecoaches, wives-and-families, Len's lack of use of Morse Code in military communications, 50plus years ago, Len's parents watching the lunar landings on TV, keyless auto security systems and more. The US railroad system, Knotts Berry Farm, wife and father- in-law were first mentioned by Ian White. White's posting made NO mention about "amateur radio homebrew" but focussed on post-1900 telegraphy, particularly on the railroads, and World War 2 where his father-in-law "pounded brass" while in the military. Actually, NONE of the postings up to 18 Feb mentioned "amateur radio homebrew" except for the second posting by Michael Black. Black correctly stated that 'Julian814's' posting didn't belong in that newsgroup. But, as stated, Miccolis HAD to vent his spite and make noise while denigrating another WITHOUT addressing any "homebrew" subjects. I didn't see a single word from Len in his long posting about amateur radio homebrew. Awwww...you wanted PRAISE and HONOR just for morse code? That's all you've been doing in the Policy newsgroup for years, expressing your displeasure (ultimately) at the FCC's elimination of the code test for an amateur radio license. Miccolis made a FACTUAL ERROR! It also contained this personal policy statement from Len: ANOTHER FACTUAL ERROR! That is NOT a "personal policy statement." It is simply a PERSONAL OPINION. Apparently NONE may have personal OPINIONS with vetting them with Miccolis first? :-) "I have nothing against telegraphic skills nor anyone using those for personal pleasure. However, in the light of advancement of the electronic arts, communications, radio, methods that ALL of us can share, I think there is an over-much emphasis by radio hobbyists on telegraphic arts. Manual telegraphy IS a historic first but it has been supplanted in practical communications means at our disposal...on land, in the air, on the sea, and in space. Tsk, tsk, Miccolis "objects" to that. Unfortunately for him it is all TRUE. The communications arts HAVE advanced far from the pre-1900 times and technology. Yes, manual telegraphy was the first electrical-means communication mode over land. On wires. Using relatively PRIMITIVE electrical technology. Yes, manual telegraphy was the first mode for the public demonstrations of "radio" as a communications medium in 1896...it was still as PRIMITIVE as the technology of early radio...using no active devices such as tubes or transistors (neither had been invented in the first decade of "radio"). Radio is about 111 years old as a communications means. No other radio service except amateur radio uses it for communications, requires it to be used, and most US radio services never bothered to require morse code when that service was begun! Every day more than a hundred million Americans are using some form of radio communications or radio relay or radio telecommand that is NOT morse code. The very last day of license testing requiring cognition of low-rate morse code is 22 February 2007...only two more days. After that, NO US amateur radio license exams will require any morse code tests. Yes, US amateurs may still USE morse code according to FCC regulations. That will help ease their personal burdens of anger, rage, spite, and other personal defects of behavior. They can re-enact their dreams of "pioneering the airwaves" and "progressing the state of the art of OOK CW" even though that had been reached decades ago by predecessors. Let those poor soul morsemen sweat and itch over the rightness of a federal decision...something done not to ease THEIR self-important delusions, but to benefit ALL. Morse code apparently means more than life itself to some of those OOK CW dreamers. Miccolis, take your aggreived soul and mighty self- importance and go somewhere where the code hive-mind is desired. There you can bitch and moan about all the upstarts, "error-making" persons who were doing actual radio operating BEFORE you were born, the so-called "moderators" who are upstaging YOUR constant attempts at moderating them. Enjoy the company among the hive- minds. It will be a comfort to you, a safety place where you can be as ****ily pedantic as you were in here. You will be applauded for such state-of-the-art policy discussions such as "bandplans of 1940." I don't expect you to correct all your own FACTUAL ERRORS you made in your recent post. After all, you will "deny" you EVER made an error! :-) That is iron-clad, predictable. :-) |

From: Dave Heil on Thu, 22 Feb
2007 15:44:05 GMT PERSON J MAKES ANOTHER FACTUAL ERROR... WHO is "person J," red-hatted one? WHO are all the other "Persons" mentioned? :-) Your posts were made long after Micheal Black advised the original poster that the SUBJECT was off-topic for the newsgroup. What you did was address a SUBJECT which didn't belong. That didn't stop Leonard H. Anderson. Feel free to address the Appelate Court of Internet Appeals, file a Notice of Intent to Sue. [Sue is the clerk of the court...] There was no overt expression of "dislike for 'CW'" by myself. Just covert expression, huh? "Covert?!?" Did you find some developing fluid to make the "secret hidden message" visible to all? :-) Or have you drunk that "developing fluid" too hastily? :-) You just HAD to say something negative or dismissive about the responses of just about anyone who posted, but that was okay. "Just about 'anyone' who posted?!?" Heh heh heh, only about some organ grinders and their little red-hatted morse monkeys who do bad imitations of Otto Preminger. ...while you made numerous lengthy, wandering responses and "made noise" despite knowing that the subject was off-topic. WHO established this "off-topic" status? YOU didn't. Miccolis didn't. RRAH is an unmoderated newsgroup. Awwww...you wanted PRAISE and HONOR just for morse code? Where was any such idea put forth? Oh, just in hundreds of past postings by the organ grinder and his little red-hatted morse monkey for years... :-) How will you ease your personal burdens of anger, rage, spite and other personal defects of behavior as described in the N2EY profile of your actions? Ooooooo! I have all those things? :-) I will continue, as I've done before, of laughing my head off at the FACTUAL ERROR-FILLED "profiles" your organ grinder cranked out. :-) I'll be able to use Morse, FM, SSB, AM, RTTY and other digital modes on the amateur radio bands today, on Friday and at any time after that date. Wonderful...who was STOPPING you before? Hollingsworth? Martin? The CIA? What will you be doing on the amateur radio bands after Friday, Len? Was I supposed to be "doing something on the amateur radio bands?" :-) "On the bands?" No, you should have written "IN" the bands. Tsk, tsk, factual English Error! Hmmm...not that it's any of YOUR nosy business, but we (that is, my wife and I) have plans and events for the week-end. The AAA 500 is on at the California Speedway in Fontana on Sunday...one example. And you may play make-believe ham radio operator in internet newsgroups. I do that?!? Oh, my, you DO have a terrible ability to read... Tsk, I've never claimed to be either an amateur radio operator or a "ham radio" operator in real life or in newsgroups, not on BBS or in correspondence with amateur radio organizations. Don't even play one on TV. You are confused and think I am someone else... The decision may or may not have been "right". History will reveal whether it was right or wrong. We can rest assured that the organ grinder and his little red-hatted morse monkey will OVER-RIDE any "decisions of history!" :-) THEY are always telling everyone what they should think! You may sweat, itch, live and die without ever having been a part of amateur radio, Len. That isn't causing me any worry. :-) It DOES seem to bother YOU a great deal! Have you sought medical help for your condition? There has never been a fellow with more self-important delusions participating in this newsgroup than Leonard H. Anderson, non-participant in amateur radio. Now, now, don't put yourself and Miccolis down so much. Either one of you are much more self-important than I. It is and has been repeated by you two in here for years. Did you know that "radio" is used in OTHER radio services and by the military and government of the USA? Really. "Amateur radio" isn't the sole user of radio. Really. You don't give orders here, Leonard. Jawhol! Gruss Gott herr Kommandant! click heels in acknowledgement You weren't a radio amateur before Jim was born and you haven't become one since Jim was born. Who is "Jim?" Is he the one cranking that rusty organ? Tsk, tsk, and doing that in public view, too!! You're irrelevant to amateur radio. So you keep saying! Well, say it enough times and maybe someone besides this "Jim" will believe you. That's the spirit of using the "Big Lie" technique of propaganda. Along comes Major Hoople to stand on the sidewalk and tell us how amateur radio should be regulated. Who is this "Major Hoople?" I don't know any "Major Hoople." You say he was in the newspaper comic strips? I never saw that strip. Did you have it mixed up with Hal Foster's "Prince Valiant?" Or Milton Caniff's "Terry and the Pirates?" "The Katzenjammer Kids?" I know of a "Major Bowes" who used to host an old, old radio broadcast show called "Major Bowes' Amateur Hour." The few times I heard that did not include anything about radio amateurs. I didn't listen to it much, so maybe other airings of that program had something about amateur radio? Your comfort is usenet, Leonard. It is? I don't think so. My comfort is my wife, a nice home (two of them, debt free), good food, good health, and a nice collection of money earned at a profession I've chosen and enjoyed in my working career. Others' mileage obviously varies... You've found a place where you can tell those upstart radio amateurs about your glory days of fifty-plus years ago. "Glory days?" Nah. Just a citizen volunteering for military service, serving and doing what he was told to do. Your organ grinding master never did that. Anyone can see it at: http://sujan.hallikainen.org/Broadca...s/My3Years.pdf About 6 MB file size, may take 18 minutes download on a dial-up connection. 20 pages, lots of photos, mostly ones I took. You can expound on your past working years, describe your northern and southern homes, tell folks about your car and prescribe sage advice about horizontally mounted loops, shielded with Reynolds Wrap (coaxial cable must have been in short supply). I can? Oh, my, you said at the beginning that I COULDN'T! Please make up your mind. The late-1960s horizontal loop was an experiment that didn't work out too well. Too much inductance, too many turns of wire...with too much inductance the resonating capacity was too small to allow fixed tuning at 60 KHz. A later version used 55 turns of #14 THHN insulation electric power wire (solid) on a 2 1/2-foot circular form (again for 60 KHz, the carrier frequency of WWVB out of Ft. Collins, CO), wrapped with twine and varnished. That was wrapped with aluminum foil for an electrostatic shield, not a continuous connection. That was wrapped in more twine and varnished three times. Two 10-foot 75 Ohm "TV cable" sections were connected to it in balanced configuration, the two coax cables' ground at the center-tap. The cable capacity makes up part of the 60 KHz resonant tuning, final trimming done by a 2-section "BC band" variable capacitor. Input below the vertically-oriented loop is to a differential FET source-follower pair to a voltage-controlled-gain differential amplifier. Oriented NE towards Ft. Collins, it provides a good signal from WWVB which is then limited as well as mildly bandpass filtered. The limiter output provides a fairly steady carrier at 60 KHz which feeds a phase-frequency-detector comparing a 60 KHz quartz-crystal oscillator which is electronically trimmed through the PLL loop filter (time-constant about 2 seconds) so that the crystal oscillator remains in phase with the WWVB carrier. Overall receiving bandwidth is narrower than 0.5 Hz so the equivalent signal-to-noise ratio is high. A second PLL uses the 60 KHz crystal oscillator as reference to compare the 10 MHz time-base oscillator of a frequency counter, both divided down to 1 Second period for the second phase- frequency detector. That way I am always assured of an accurate frequency counter reading good to better than 100 Parts Per Billion (not Million). Note: The "receiver" (a basic TRF configuration) is held stabilized in a slow-speed AGC loop with a small meter readout of carrier level. Limiter action is about 55 db compression so the AGC loop turned out to be redundant. The observed maximum-to-minimum signal strength from WWVB (about 1 KMile distant) has been less than 10 db (in power) during about two years of use. This is less than the predicted variations published by NIST on their time- frequency pages at www.nist.gov. Observed transients and noise at the limiter output from all other electrical sources in the household are no more than about -30 dbm of minimum received carrier level. Internal DC supply is double and triple series-regulated to obtain +12 and +5 VDC operating voltages. I may add a battery-backup inside the 1/10th cubic foot enclosure later to replace the external small UPS. It would be nice to compare the 10 KHz internal divider signal agains a rubidium oscillator standard in the future. Right now I am satisfied with the accuracy checked in several other ways, no need for doing an Allan Variance. Thanks for asking... |
