Hi Hank,

This again points out the fallacy of treating different matches as
having equal outcomes.

A simple, intuitive test of your statement about would ask the
question:
"Who needs a tuner for mismatches then?"

No doubt the thread will enlarge with discourse on the theory of
Thevenin (Norton by implication), Conjugation, Efficiency, Max
available power, Max power transfer, and any number of other mantras
dear to the heart. And yet none of them will explain that if we have:
transmitter cannot absorb power it reflects it to the antenna ad infinitum.

"Who needs a tuner for mismatches then?"

Saving a few hundred rounds of such non-answers, and suspecting if I
held feet to the fire, the discussion would then turn to answering
"Who needs a tuner for mismatches then?"
in terms of psychology:
"A tuner makes the transmitter happy."

A such, it reduces to the economy of time. If you are in this hobby
long enough, the investment in a tuner will yield that same level of
transmitter happiness at a lesser expense than would monthly visits to
the pharmacist for Prozac.
