. . . Do you think W7EL would ever make a prediction based on the meager amount of information provided? :-) A few years ago he provided some information but kept changing parameters daily until I got tired and withdrew my estimate. But it turned out in the end that I was pretty close. W7EL wrote: That's entirely untrue. The record is readily available via groups.google.com for anyone interested in seeing what really happened. The thread was "Current in antenna loading coils controversy (long)", in November 2003. Roy Lewallen, W7EL I'm also a victim of Cecil's twisted reality Roy. I offered to make a measurement if Cecil would even loosely predict results and tell everyone in advance what they would mean. When he didn't respond, I made the measurements anyway. Time delay measurements of current at each terminal of a "bug-catcher style" loading coil are now at: http://www.w8ji.com/inductor_current_time_delay.htm Cecil is also re-writing what I said on QRZ. If anyone reads back through his posts on this list, they will eventually find a post where he acknowledges a phase measurement I posted on QRZ was in voltage across the source compared to voltage across a load resistance. My response was on Mar 9 2006 at 10:03 PM When I measured CURRENT at each end of the inductor (in that case the inductor was a 1-1/4" long iron core 100uH choke), current had no detectable amplitude or phase shift. Voltage from the generator was not in phase with current because of the inductive reactance, but current had the same relationship at each end of the choke. Of course Cecil wrote that off as "measuring standing wave current that is current that doesn't flow", and then succeeded in driving off someone who was trying to straighten him out on that. All of that is also in this thread for anyone to read. The exact text is: Cecil, Good grief!!!! I said several times that the standing wave does not move. I also said the "wave" is not the same thing as the "current". The current is nonzero even though the wave is stationary. At this point it is obvious that you are just interested in causing a fuss, and not the slightest bit interested in reaching any sort of resolution of this item. Bye. 73, Gene W4SZ There really isn't anything anyone can do to resolve any disagreement with Cecil, because as soon as he frustrates them into giving up he will rewrite everything that was said. My only hope is that people who want to learn will look at the data and understand how an inductor really works. It would be comical to watch Cecil twist reality if it wasn't sad. The sad part is there will be some people out there who will accept his twisted logic. They won't take the time to read or ask hard questions. The good part is my understanding of what goes on in a loading coil has been improved, and I have more data for my web pages. Fortunately the very high traffic volume into that site keeps it at the top of search engines. If you or anyone else finds anything that will clarify inductor behavior, please let me know. I don't learn much from arguing with Cecil, but I do learn from other contributors to this thread. I'd like to thank everyone who has contributed. Even if it doesn't help everyone, it helps some people. 73 Tom W8JI |
