Sorry, that statement is theoretical and has been proved
untrue for real-world generators unless heroic measures
are taken, e.g. circulators.

With regards to Icom equipment, there is no dispute of the above
fact, but rather, there is dispute about whether the output
impedance of the transmitter can be characterized.

Yes, real world generators have a habit of not abiding
by theory.

Ramo and Whinnery's warning must be taken seriously but applies
only with reference to an equivalent circuit. If the actual
circuit is as described, then the caution does not apply.

But Keith, you have *never* described an actual circuit. All
you have described are equivalent circuits. What tube do
you use? What transistor do you use? What tank circuit do
you use? What load line do you use? Where the heck is your
schematic?

It is well understood in all the literature how the generator
described above handles reflections.

Please give us a schematic of the described generator.

So sad.
