Well Bob, I don't want you to not operate the amp based solely on my
ideas and the math.  A whole lot of folks run them all the time with
good results.  Besides some of the science in all this is not exact
anyway.  I would just limit TX times much more so than old buzzard
when running a linear amp...  Go for it Bob, it's just something to
consider...

73 & good luck,
Brian / wa5am
