Hi Nate,

I think I get what you are saying, but reducing power will not change
the SWR (since it is a ratio). I think in reality that there is some
threshold for reflected power that the transmitter has and above that
level it will cut down on the output power to get the reflected power
below that level.

One thing which that article seems (in a quick skim) to fail to
address is that reflected power can damage a transmitter. This
aggressive power reduction MAY be necessary to protect the transmitter
output stage. It isn't intended to protect the stuff outside of the
transmitter (antenna, feedline, etc.) and so it would not be "better"
if the transmitter did not cut back. That being said, it could be that
some transmitters are too aggressive in doing so.
