(You seemed to miss the single smiley on my previous message, so I
though I would try a few more.)


The "proof" of something when one does not have adequate information is
often called "faith".


More to the point, there are several possible answers.

1. Who cares? If you can't measure it and you can't adjust it, just
forget about it. Lack of maximum power transfer is rarely fatal.

2. If you are operating an amateur radio station just twist the knobs on
the tuner until the transmitter is happy.

3. If you are designing a system to be sent into space then analyze and
test the heck out of it.

I didn't say anything about a steam engine, Gene. The question is:
How do you prove a conjugate match exists through measurements when
you are completely ignorant of the source impedance?
