However a PA is not a 50 Ohms source

Hi Wimpie,

You say this like others, with the air of "knowing." However, when I
ask in response of those who "know" what the PA is NOT, what IS it?

Give me the Z value of your transmitter. Specify all initial
conditions.

We have had lengthy correspondence with Walt Maxwell's very rigorously
measured Kenwood TS830s that demonstrates a Z of 50 Ohms, or nearly
that as is practicable (say +/- 20%); and yet your voice was missing
from this discussion with evidence to the contrary.
