Roy, to cut things short, why don't you just say SWR meters don't
measure SWR on anything.


He did, he just felt compelled to add a page or so of explaination.

All they do is indicate whether or not the
transmitter is terminated with its correct load resistance. So they
are quite useful.


Well, to be picky all they do is indicate the divergence from the Zo of
the meter, in a certain way. If the TX is designed for that Zo then
they do what you say, and they're quite useful.

They won't even tell you what the load resistance actually is unless
the load is exactly correct.


Yes

Stop fooling and confusing yourselves. The solution to everybody's
problems is simple - just change the name of the thing to TLI.
(Transmitter Loading Indicator).


Hmm. I'll stick with SWR meter -- which it is if it's used properly.
