Perhaps if you didn't have your head so far up Lennie's rectum, you might have had the opporutnity to read it in any one of several HUNDRED anti-Amateur rants he's posted here. Sorry you missed it. (More like IGNORED it.) Steve, K4YZ Sorry, Steve, but my head is not up Len's rectum. Yes, it is. More like your head is up your own rectum. If you should ever pull it out, it will become the "POP" heard round the world! I am sure you wiash this were true. If you cannot produce the rant, you'll just have to troll elsewhere. Sorry, Brain...No need to waste that much bandwidth with material that Lennie already wasted bandwidth on in the first place. Now, try and find something you KNOW something about to talk about, Brain. So far you can discount DXpeditions, reciprocal licensing, MARS, and emergency communications. You've failed miserably in ALL of these subjects. Steve, K4YZ |

Tsk, tsk, tsk...still making typos when oh, so angry? :-) You have a "wiashing machine" there? A "clothes driaer?" Appliance technology marches on...

Everyone just loves all this "meaningful discussion" stuff. :-) Now, try and find something you KNOW something about to talk about, Brain. So far you can discount DXpeditions, reciprocal licensing, MARS, and emergency communications. You've failed miserably in ALL of these subjects. "MARS is amateur radio." Nursie is a veteran of "hostile actions." Nursie shopped at the HRO in Burbank, CA, before they even moved out of their Van Nuys location... Everyone just loves this "meaningful discussion" stuff. :-) |

We keep hoping for that "perfect" antenna. An IEEE publication back in 1995 pointed out that the Northern Lights are caused by ions that are far too small to be efficient radiators of light - and yet they radiate light. In theory, an antenna can be vanishingly small and yet be efficient - and even possess gain! If any one has a 6 inch whip with a 3 dBi gain on 75 meters, let me know. I'd like to try it first, however. Don't ask for money up front like all of the notes I receive about transferring $10,000,000.00 US for which I receive $1,000,000.00 - uh, but have to send someone some up front cash to ensure the account is good  )73 from Rochester, NY Jim AA2QA --- Outgoing mail is certified Virus Free.

With 16 big K of ram (and I ordered a 12 K memory board from another vendor - a total of 28 K in the computer), and a text only monitor and tape recorder for mass storage, the thing set me back way over $2,000.00 - *in 1976*! 73 from Rochester, NY Jim AA2QA --- Outgoing mail is certified Virus Free.

OTOH we don't have anything to go on other than "continuously loaded monopole". Just what is that anyhow? a 50 ohm resistor on the end of a pole? Maybe he's got a real advance, maybe it's all just hype. I'll reserve judgement until there's some real info available. Extraordinary claims require extraordinary proof. I'll not only reserve judgment, but am highly skeptical about it at the same time. This sort of thing is almost like the audiophile stuff I posted the other day. And what I have seen so far on this breakthrough is feelgood stuff. I just wonder why an 80 to 100 percent efficient antenna melts when hit with a "whopping" 100 watts of power? If somebody told you, back about 1975, that in 25 years you'd have a computer on your desk that had a 500 MHz CPU, over 100 MB of memory and 10 GB of disk space, and cost about $200 complete (1975 dollars) what would you have said? First I would have said "kewl" or whatever I was saying in 1975. (probably more like "Far out, Dude!") I wouldn't have seen any mechanical limitations however. I would have marveled at getting so much stuff on one integrated circuit, noting that the size was limited by the limitations of light. I don't think I would have thought of X-ray lithography at the time. But I would have believed that such a thing could be done. The areas that I would be most surprised at would be that the computer would have a single CPU that did all the processing. I would wonder why on earth we weren't using massively parallel processing. In fact, I still do. Love my G5 dual processor! The most mind boggling thing to me would have been the software and applications for the computer of 2000 or 2004. Soundcard applications, GUI's, graphics and all that other stuff was simply not on my radar screen at that point. - Mike KB3EIA - |

I'll stick with my "snap judgement", the thing is guilty until proven innocent. 73 de Jim, N2EY w3rv |
