Hello Richard, I must be honest with you, Richard, for over the years I have often been in a quandary after reading some of your posts--I simply don't comprehent what you're saying in them. I often have to turn to look at some one else and ask " wad't he say? wad't he say?" For example, I don't know what a 'kabuki' is. Hi Walt, Your confusion is well founded. :-) Kabuki - Japanese theatre with very elaborate costumes and highly mannered acting. It is presented in day long plays that many in the audience feel perfectly at ease with watching, talking to a neighbor, eating a meal during the performance or taking a break and coming back to after an hour or so. You say my numbers show evidence of a source resistance. Then you also say "This real resistance is the experience of EVERY correspondent here." On the contrary, my understanding is that Keith Dysart and Owen Duffy don't agree with that. Have I misunderstood their posts? Then you say,"What is more comic is both sides couldn't agree more! Truly Kabuki." Again, what is 'kabuki'? In other words, to both sides agree or disagree? Which is it? Both. However, as to why? They themselves are notably absent from this discussion. I mark this as a lack of commitment at the bench to obtain contrary evidence. Perhaps it is casual indifference carefully woven into passionate and emphatic negations. Such bipolar swings is what I term as truly Kabuki. In another paragraph you say, "As for your position, your proposal appears to exhibit source resistance where you deny its reality. This is a longstanding difference we have had and I presume will never be bridged." I totally misunderstand that statement, especially a longstanding difference that I didn't know we had. And although my measurements of source impedance (or resistance) indicate their reality, I have never knowingly denied their reality. I can't understand how you could have reasoned that I denied it.

It conforms to half the other writers half the time (who can tell with all their mannered elaboration?). If you can allow that Rp is real resistance, all fine and well. If it takes more than three sentences to state it is not, then that is truly Kabuki. Three sentences may not completely give you enough freedom of expression, but if I see a fire hose response - that is just too much material to justify parsing for a clear answer. Now we come to the "basis" for my measurements. You state that my measurements appear to be on the basis of image impedances. According to my editions of both Terman and Everitt, 'image' impedances mean that when the generator is connected to the input terminals of the network the impedances looking in both directions at the output terminals of a network are equal. I understand that this can be true if the impedances are purely resistive, but I can't see how this could be true when the impedances are complex, having reactive components. Well, you have the material at hand. Terman offers succinct meaning. A position is usually in one place. That place is as Terman and NBS writer Stephen Adam (strictly) terms it as "basis." And I asked what basis you use. Please consult the strict usages of the literal word basis (and not the informal understanding of "how") to avoid mixing them. Your pleas are often couched with conjugate basis and you attempt to prove them with image-Z basis. They should not be intermingled. If the impedances in both direction contain equal reactances (not opposite), then delivery of maximum available power cannot be delivered. For the maximum power to be delivered the reactances looking in opposite directions MUST also be OPPOSITE, describing a conjugate relationship, not an image relationship. Unfortunately, my editions of Terman must be different from yours, You do not have "Electronic and Radio Engineering?" So Richard, let me get this straight--are you agreeing with my position or disagreeing? I take no position beyond your data clearly exhibiting the nature of what Terman describes in pages I have referenced. My professional experience has been invested with measuring real resistance to NBS precision and accuracy - this includes plate and collector resistances (albeit at vastly less resolution than standard resistors and such). Energy creates heat in real resistors. The combination of phases and energies in a resistance still gives rise to heat, if by different degrees that follow phase relationships of all perceived sources. Heat can increase through soaking (a steady elevated current) or through breakdown (the quick flash of an intense voltage arc). These two are very common (even if only on rare occasions) experiences of EVERY correspodent with their own equipment. It is exceptional to deny this. We have exceptional threads. Your data does not contradict any of my points - the question is: does your position contradict Terman's discussion and my experience? I have trouble with your mixed basis discussion that clouds my ability to resolve where you stand. Other writers seem to go both ways without any data of their own measurements to inform me about their judgment having authority. Yours is the only data (aside from my own offered earlier in separate discussion) on the table - and it suits me fine. 73's Richard Clark, KB7QHC |
