Default Where does it go? (mismatched power)

OK. Thank you very much. This clarify so much the issue to me. Please,
another question: On the same system-example, who does not agree with
the notion that the reflected power is never dissipated in Thevenin
Rs? (I am referring to habitual posters in these threads, of course)


Thevenin's theorem says nothing of what happens inside the source (eg
dissipation), or how the source may be implemented.

It is the implementation of the source that provides the answer to your
question, and the word "never" is too strong for the general case.

In respect of typical HF ham transmitters, you may find my article
entitled "Does SWR damage HF ham transmitters?" at
http://vk1od.net/blog/?p=1081 of interest.
