Hi Cecil,

So, a source exhibiting 200 Ohms Resistive feeding a 50 Ohm line that
is then terminated in a load of 200 Ohms Resistive exhibits what SWR?

The absence of a numeric answer is par for the course here. The
answer, of course, can be found in Chipman's text but that requires
the act of reading, not snipping (which would still be available to
the literate). Many here stumble when it comes to measuring SWR
employing (in this case) 2 resistors and a hank of line - how they
could imagine they respond faithfully to more elaborate enquiries is
quite amusing, especially when they argue the Source Z has nothing to
do with it.

My mental image of that assemblage of pundits is that of them crowded
on a small desert isle, each proclaiming it to be a vast, lush
continent. Another SWR Don added to that bunch will teeter someone
into the brine. ;-)

Do any of you know how to tread water? Seems to be the perfect
Darwinian thinning mechanism; but in fact most already tread water at
high tide.
