That you didn't read the published material does not mean that the material did not exist. The synthesizer phase noise issue was debated well before 1990. It is referred to in QST product reviews of ~20 years ago. Thus the tube radio. No synthesizer. What a wunderful way around it. Hi, hi! Ever see a mention of "phase noise" causing all the front end noise in receivers back 20 years ago? :-) Nope. Just plain old "kay-tee-delta-eff" random noise. That's still around, still the limiting factor in sensitivity. Jimmie, putting on his "kluge clothes," said that "phase noise" is THE limiting factor in receiver sensitivity. He has two degrees and is a PCTA extra...no one can argue with him. :-) It only came up when a frequency synthesizer was incorporated? :-) Synthesizers were in wide use prior to 1990. Extreme wide use. The phase noise issue became important as synthesizer circuits became common in transceivers. The phase noise issue became an issue with the first synthesizer circuit. I'll invite to read up on the subject. Ditto. I've provided several urls. Ho ho! There are numerous other sources of information on the subject. Why not avail yourself of some of them? Compare the transmitted noise spectra of an SG2020, Elecraft K2, and K1. Guess where that noise comes from? Synthesizer circuits? Tsk. Apparently random noise at the input has disappeared with the advent of the frequency synthesizers. :-) R70s were made 1982-84 (approximately), so the design is at least 23 years old (1981). You frequenctly denigrate others as "behind the times", yet the R70 is the newest/most modern piece of HF radio equipment you mention owning. Just another example of "do as Len says, not as Len does". That little Icom R-70 still works fine, as advertised. While I doubt that the receiver functions as advertised, I have no trouble believing that it works as designed. Ya missed the point. Ooops! Other designs are criticized because of age - but not the R-70. Guess why. Schindler? Nah. Jimmie knows I have an Icom R-70. THAT is the reason for his diatribe. Doesn't matter what the model is, if I have it, it must be no good! :-) I've got one. You don't. :-) Don't want one. If somebody gave me one, I'd sell it. And do what with the money? Buy running shoes? Almost anything but buy a (hack, ptui) ready-built ham radio! :-) I'm sure it is quite a nice piece of equipment for the casual SWL. I'm happy for you. Happiness abounds in RRAP! Only among the mighty macho morsemen... The only thing I "recycled" was some paper to get one in working order. :-) I recall you mentioning that. "Cash" wasn't it? Use of a credit card would have muddied the waters. I paid cash for all the parts in the Type 7.... What? No TV transformer yoke? ...or the color burst crystal. :-) "Phase noise" wasn't a big buzzword then. It has a three-loop PLL in it plus a microcontroller. Sensitivity is still good and comparable with any contemporary HF receiver. "Phase noise" wasn't a big buzz word in the Icom engineering and sales bunch. Elsewhere, the use of the term was already common. Like amongst hams. Like with the first synthesized circuit radios??? And of course, those very first synthisized circuit radios were ham radios! Hi, hi! Jimmie has wide experience in all radio...comes from "serving his country" by having a ham license and reading all those QSTs stacked next to his kluge. I've yet to get close to the concept of sitting around a shack making as many contacts as possible in a given time as any "sport." It's called "competition". Nope, it's called contesting. Best of Luck. Skill and endurance are certainly big factors in winning any amateur radio contest. Somebody's half-way awake. Missed the boat ont he sport concept. He's not as good a sport as he pretends... Neither is that activity "pioneering the ariwaves" nor any sort of "training for emergencies" to reasonable-thinking human beans. Did you ask any? No claims for contests as pioneering the "ariwaves" have been made. Any on-air activity which requires speedy, accurate operation is good training for emergency situations. Contest operation also points up the weak points in any radio station. The contest and DX folks have pushed the need for better rigs for decades. Where money is no object. I thought you guys were focused on third-worlders who had to self-manufacture CW only circuits? Wherethere is no money. Which is it? They don't really know. The one they are sure of is that morse code skill is the ultimate, the ne plus ultra, of all radio skill. Do morse or be considered lesser. :-) Like chess or checkers or board games, radio contesting is a GAME. So are all sports. Like the Olympic GAMES... Messing with Steve is a game. Emergency comms is no game. MARS is NOT Amateur Radio. PCTA fantasy says it IS. Excuse me...IS. :-) Jimmie "serves his country" by engaging in the hobby of ham radio. He said so. We can't argue anything that he's said. There are some similarities. A good strategy, playing within the rules Rules RULES??? Like copying the W1AW message the day before? Hello Kelly??? Hi, hi! These guys obey no rules. They are the elite! Rules are for the other hams. In one way, that's nice...we get to "eat cake" when we have no bread. Marie A. once said that, got so upset she lost her head... and some luck are involved. No board games that I'm aware of require putting up big antennas at height, putting together a radio station or planning sleep breaks. Why must you confine your "game" to board games??? Are road rally's played on a board? PCTA fantasies are done in their heads. Think car racing. Bicycle racing (Lance Armstrong wasn't riding a three-speed with baloon tires) Allow Bill Sohl to speak of road rally's. If you dare. It is FAR from an ATHLETIC sport. Not if done correctly. Let's see....I run as exercise and also a sport. Done two marathons and more half-marathons, ten-milers, 10Ks and 5 milers than I can recall. Mike Coslo is a hockey player. What sports do others participate in? ot as spectators! Lying? Robeson leads. That's a PCTA radiosport. :-) You *do* sound just like him, Len. Lots of words and lots of put-downs and lots of theory. But in terms of actual radios built on your own time, with your own resources, from your own design....nada. Zip. Zilch. Zero. Nothing. Not that anyone here knows about in all your years and petabytes of posting. If I had extra copies, I could, with a year or so off to do it, digitize those things and put them on a website that allowed at least 100 MB user space. That includes corporate documents (public) along with photographs. The challenge is for *homebrew* radio projects. Not stuff done for work. Yet most of the HEROES of amateur radio were doing their heroic work as PROFESSIONALS!!! Explain. Explain again! Tsk. Jimmie NEVER said what HE does at his regular job. All he's admitted to was in one Comment on one of the petitions at the FCC that he is engaged in vehicular propulsion systems. That's all. No details, just a general statement. Well, Jimmie must do SUCH good work at work that he doesn't think any of it is a challenge. Tsk. No enthusiasm shown for what he does for a living. The "challenge" is to build kluges in the shack and then try to get everyone to admire and respect his work. Not worth it, since the typical PCTA extra "commentary" (to use a word very loosely) would be totally derogatory. You mean you fear reaping what you sow? "We" only fear reaping what Steve sows. Spooky dood. Low-class ideas. No fear here. No pity either. Tsk. My little text and photo memorabilia on the ADA assignment takes 6 MB in PDF. Did you design and build ADA on your own time, with your own resources? Did you build the VE system on your own time, with your own resources? Either HE did or he aligns hisself in the same league by virtue of the document about a hobby he says is "service to the country!" We can't argue with Homeland Security these days... YOU have REJECTED simple things like a digitized license repro in the past. I didn't ask for it. I had already said I'd take your word that you had one. But you sent me*several* unsolicited emails with unknown attachments of large size. (Ever hear of compressing a file before sending?). How was I to know what they were? I found out later that one attachement was a picture that contained male nudity. Not my cup of tea, so to speak. Must have been right up Steve's foci! "Male nudity?" In that nice aerial photo of a converted B-26 in flight it is impossible to tell gender. :-) You would be expected to reject anything I present...as "credentials" or whatever real proof there is...and there is a lot of it. It's real simple, Len: Pick an HF radio project that you did in your home workshop as a "hobby" activity. Not something for work, or something you did as part of a group, but something you dreamed up and built yourself, just for the fun of it. Not some accessory, either - a complete receiver, transmitter or transceiver. Put a picture and a short description on your AOL homepage, just like I did. We don't need megabytes or a long diatribe. Just a .jpg and a short description. My project is out there for all to see. Where's yours? Or are you too afraid of what others will say? Was Fesseden's projects for amateur radio? Marconi? All of the broadcasting stations I worked in all do AM by sticking a single microphone in the antenna leads...NOT. :-) All of the broadcasting stations I worked in all did morse code news...NOT. Actually, I DO have enough material that could be digitized from various employments (even has my picture in some of them), enough to fill at least 100 MB of filespace. Why bother? Just to answer Jimmie's so-called challenge? He thinks so. He says it enough to make it a demand. I DO have some pictures of stuff I've done personally, again enough to fill lots of filespace. I'm even taking progress pictures as a couple projects get done in various stages. For MY pleasure and maybe some ideas for a very few others who I've known for some time. I'm not out in any "competition" via websites appearance or that sort of thing. I'm not out to garner admiration and respect through websites. Jimmie got bent out of shape by not getting gushing admiration or respect for his kluges built from tubes in the 1990s. Saying that the photo shows neatness isn't enough. We were all supposed to applaud and make gratuitous nine-nice noises? As to the "ability to draw schematics from memory," I don't recall a single design review meeting at work where a participant was NOT able to recall schematics from memory...of their project, or others projects that they were peripherally involved in. That includes ALL details pertinent, such as environmental conditions, some mechanical structural considerations and the like. A federal REGULATION requiring morse code testing in order to get an AMATEUR license to operate on HF is NOT "live and let live." Yes, it is. It is not. No other AMERICAN radio service requires such. To the PCTA extra, the ONLY way to be American is to take the code test...like THEY did. Ho hum. Would you mind saying that just one more time for the record? Please don't encourage the guru of here...Jimmie will bust a gut writing and writing and writing and writing "truth" (as only he knows). And all PCTA's are actually against doing away with the code test on the ground that it will diminish their status as "REAL Hams." That is IT in a nutshell. Quintescense of their existace. :-) |
