The source Z of a typical tx having a single-ended Class C PA is just a few
ohms. The exact value depends on circuit design and tuning adjustments.
Heavy loading of the output tuning network of the PA reduces the return loss
looking back into the tx, and lighter loading improves it.

Please read my post using the new subject line "Tx Source Impedance & Load
Reflections" that I started for this a few minutes ago. The paper I refer
to and quote there (not mine) is accepted in the broadcast industry as a
benchmark on this subject.

Hi Richard,

This quote above bears directly to one of my observations. You define
by negatives, and that is a shoddy technical discussion worthy of the
creationist argument.

Tell us what it IS instead.
