If you don't believe there's a solution to the example Keith posted,
you have no right to believe in the results of a measurement with a
vector network analyzer, and you should certainly not trust the
indicated output level of any signal generator.

Methinks you have missed the context of the discussion.
If the model doesn't work for an IC-706 it is not much
use to amateur radio operators. I have already said that
a valid model can be had for a signal generator equipped
with a circulator load.

The only problem with this statement is the assumption that
the result can only be achieved with a circulator. It only
takes a 10 cent resistor. You really should put down your
optics books for a few hours and crack open a basic circuit
theory or transmission line text. Or google, "'lattice
diagrams' reflection". For matching at the source,
only 10 cent resistors are used.
