Yes, as a matter of fact, I have. It tends to support my argument
with Jeff Anderson, wa6ahl, on this newsgroup from about a decade
ago, but is much more thorough and eloquent than I ever could be.

I can`t read pdf.

I learned about maximum power transfer in the 1940`s and it hasn`t
changed.

Terman says in his 1955 edition on page 76:

"Alternatively, a load impedance may be matched to a source of power in
such a way as to make the power delivered to the load a maximum. The
power delivered to the load under these conditions is termed "available
power" of a power source.

This is accomplished by making the load impedance the conjugate of the
generator impedance as defined by Thevenin`s theorem."

Anything else I need to know is likely also clearly explained by Terman.

What a load of crap!

The only difficulty in the MPTT occurs when some folks create new
definitions and new constraints that are not shared by others in the
discussion. Allowing the problem to float at will means that the
solutions will float as well.

The longstanding MPTT argument in amateur radio circles is not really
about power transfer and conjugate matching. The argument is typically
about what happens to the source impedance under varying load conditions.

Steam engines? Gear boxes? Yeah, sure, they help a lot.

That's a fair question, Gene - what does happen to the source
impedance under varying load conditions?

While you're at it, could you please explain how you would separate
the issues of maximum power transfer and conjugate matching from the
question of what happens to the source impedance under varying load
conditions?

I have no problem in supplying copies of the article to anyone who
requests a particular format by e-mail - available choices are pdf,
html, or Word for Windows 97 or 2003. The complete file is
approximately 1 MB in any of the formats.
