Jim & Richard,

I guess I'll retire gracefully because I'm not privy to the "history"
between individuals on this Forum and I'm now not even sure when
answers are to be taken seriously or as a joke.

Jim's most recent posting is a good example. We were talking about
measuring current along a dipole. I assumed that would mean measuring
the standing-wave current, but Jim introduced the notion of measuring
travelling wave currents.

A point of correction here. I believe you will find the notion detailed
on Cecil's web page.

When challenged as to how we might do that,
we got a URL pointing us to a simple standing wave meter - it
certainly can't discriminate Forward and Reverse.

Please let me apologize for my error about the nature of the article.
You are correct. The 'calibration fixture' featured in the 2nd
photograph is directional. An examination of its inner workings would of
course reveal circuits which measure currents and voltages in traveling
waves. It is to circuits such as those that I have referred.

From other postings I've read I take Jim to be a pretty knowledgeable
guy - so this has to be a wind-up, right?

He's a guy with a limited amount of time and patience honestly
attempting to subvert the ridiculous by stating the obvious. Most
everyone here has already given up trying. Good luck to you, should you
decide to try it.
