![]() Roy Lewallen wrote in message ... Things are looking up. Instead of patently false statements, you've advanced to musings that simply make no sense. Since most readers will hopefully recognize them for what they are, no response is necessary. Actually, no rational response is even possible. Hi Roy, If what I am saying makes no sense, then the information contained in the NEC2 documentation must be a fairy tale and you must be Merlin the magician. I invite everyone to take the time to look at section 3 "Transmission line modeling" on page 72, of the NEC2 documentation. http://www.nec2.org/other/nec2prt1.pdf It explains the uses of both implicit and explicit tx line models, and under what conditions the explicit model (thin-wire kernel) should be used. Looking a look at previous statements; First, the thin wire kernel is invoked automatically: The extended thin wire kernel is invoked automatically when the model is such that it's needed, according to the criteria given in the NEC manual. Then the 2-port network is invoked automatically: I clearly stated in an earlier posting that EZNEC implements the extended thick-wire kernel as required by the model. (The thin-wire kernel is the default.) And the thin-wire kernel now becomes the default. ("default" implies no need to "invoke" as it is the preferred function by default - which makes no sense, since the 2-port network has the most common usage - W8JK, log periodic dipoles, etc., etc., and uses less resources.) The NEC2 documentation even suggests there may be instances where both models should be implemented simultaneously. When asked for an explanation of these contradiction, I get my character assassinated instead. So now we're supposed to believe either the thin-wire kernel or the 2-port network is invoked automatically, determined by a *mysterious* set of criteria. Mysterious simply because that criteria cannot be divulged... This is real science, indeed. Given that no one can ascertain which tx line model is being implemented, it leaves any resulting outcome ITR in question! I suggest we have here a situation akin to VP Cheney giving disingenuous excuses as to why no one should see the records of his covert energy meetings. Stonewalling will prove to be an exercise in futility as the truth will come out, one way or another! 73 de Chuck, WA7RAI Roy Lewallen, W7EL Chuck wrote: Roy Lewallen wrote in message ...

Hi Roy, For clarity, let it be established that the term "wire kernel" and "wire model" (the term used in the NEC2d documentation) will be considered as one and the same in this discussion. That said, I find it extremely hard to believe that the wire model used for interconnecting tx lines, which normally would be implemented only in the special case of unbalanced terminations, and one that uses the most resources, would be designated as the default wire model. It defies all logic. When asked what criteria your program uses to determine which wire model to implement, and why it is not a choice the user can make - as it should be - you responded with a rather paranoid and pejorative diatribe attacking my character... what am I supposed to assume from that? In any event, these were honest questions which you chose to evade, and continue to do so. All things considered, it is easy to make the assumption that the thin-wire model is not implemented in EZNEC, and you're simply trying to spin your way out of a hole. Shame on you! 73 de Chuck, WA7RAI |
