Not being particularly knowledgeable, and taking your advice about the
information's availability (seeing that I provided the link, not you):
"Each module is conservatively rated to produce
850W of power into a system VSWR of 1.5:11"

And so it is when operating as a PA output module, when both sides of the
module are active. In IPA service only one side is active. The words on
the website say so.

Let's see, I have offered an analysis that supports your thesis that
the efficiency of this transmitters elements are ballpark 80% and you
say I am WRONG? What a hoot!

Only by an absurd conclusion that to get there "the IPA (an identical 80%
efficiency module) and control circuitry to absorb 3.5KW to deliver the
drive of .845KW." Note also your incorrect value for IPA output power. It
is never more than 425W per 5kW (or less) block of PAs. If more PAs are
used in that power level tx, another IPA and PA block are added. Of course,
you would know that if you took the time to read and absorb the website
data.

I can only wonder why you can't offer your own numbers to show my
error. :-) I originally wondered why you couldn't offer your own
numbers and carry your own water. Go figure....

Honestly, given your penchant to ridicule and intimidate people in this
newsgroup, I have little motivation to carry your water. There is much data
about these txs on the Harris website, free for the reading. I am through
trying to set you straight.

It is incredible how you, as someone with barely a perfunctory understanding
of this transmitter system, feels qualified to argue about it here with
someone who has been part of its development team. "Go figure..."
