But the goal of such "fights" should be altering other's opinions. How's that been working out for you? ;-) That's not my goal at all, John. My goal is to discuss the technical facts. I really don't care if anyone "alters their opinions" or not. That has been a personality characteristic since my early days. My sister just remarked on that same fact a few days ago. She said, "You have never cared what other people think about you." It wasn't a criticism, just an observation. We may understand the results of Tom's latest measurement by considering the following: 50 ohm source===1 WL 50 ohm lossless coax===8+j2500 load Since the transmission line is lossless, this doesn't change anything except for the additional one cycle delay through the line. What's the system SWR? I get 16000:1. I asked Tom to measure the currents in the absence of a high SWR and he takes his measurements in a 16000:1 SWR environment. How well do you think he honored my request for an SWR of 1:1? Shucks, he only missed it by 1,600,000%. :-) There is essentially no net energy flow in the above network. Why are we suprised to measure equal standing wave currents on each side of the coil? It wouldn't have surprised me if Tom had measured *zero* phase shift just like the lumped-circuit model predicts. The traveling- wave delay through a coil simply cannot be measured using Tom's methods. -- 73, Cecil http://www.qsl.net/w5dxp |
