A two-terminal network is different from a four-terminal network. This appears to be an unusual definition. Not unusual at all, Gene. The two input terminals to the black box are on one side. The two output terminals from the black box are on the other side. The impedance discontinuity is inside the box. The black box is extremely small. Give me the four s-parameters, s11, s12, s21, and s22 and I can tell you virtually everything about what is inside the black box without even applying a signal. -- 73, Cecil http://www.w5dxp.com |

Nobody ever said anything about the "other side" of the black box. Everything has been referenced to "the point where two pieces of feedline are connected." Nobody is trying to suggest that what is inside one black box is identical to what is inside another black box. The only thing known is that the *two* accessible terminals to each of the black boxes show the same specific impedance at the given frequency. Nothing else. Yet by your models and math the black boxes don't behave the same in your test circuit. You still have not addressed the original question posed by Keith. 73, Gene W4SZ |

I see that the smudge pots have been lit and the hand waving,
misdirection, and desperate attempts at changing the subject begins. As they have so many times before. What a waste of all that alleged IQ. Roy Lewallen, W7EL |

Everyone on here with the exception of the gifted one has known for the last 3 days that Richard has been just pulling his bobber under. He finally picked up on it this morning and decided to stop wasting his time. Now if he would only make that a promise! W4ZCB |

As for your last sentence. The "he" is rather unspecific as two correspondents made a promise (perhaps not so well timed as to fit your observation here). However, I too will sit on the edge of my seat in wonderment to that outcome. 73's Richard Clark, KB7QHC |

BTW, did you just by any chance ever work for me at the PME Lab in Hawaii ? W4ZCB |

Did that fellow remind you of me? Well, to cut to the chase, I was SUBLANT, USS Holland AS-32, Nuclear Navy; and as far as I know, the closest point of approach would have been Guam (aside from our time in the yards at Bremerton, across the water from where I live now). 73's Richard Clark, KB7QHC |

I'm a simple trusting person who tries to see the good in everyone, even Richard C. Please pick a technical subject upon which we disagree and let's discuss it like technical gentlemen. -- 73, Cecil http://www.w5dxp.com |

What a waste of all that alleged IQ. Do you think that waving your hands and posting gobblegook like the above is any better? Please, please, make a technical statement with which you know I disagree and let's discuss it like mature individuals. -- 73, Cecil http://www.w5dxp.com |
