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.

Roy,
I'm also a victim of Cecil's twicted reality now.
I offered to make a measurement if he would even loosely predict
results and tell us 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
syle" loading coil are now at:

Cecils is also writing what I said on QRZ. If anyone reads back through
his dozens and dozens of waffling posts, eventually they will find a
post where he acknowledges a phase delay I posed on QRZ was in voltage
across the source compared to voltage across a load resistance.
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 suceeded 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.
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.
