Ken,
Thanks, appreciate the link. This document adds a few details to what I had on
hand. Good to know the high-split Mitreks weren't prone to the spurs when
duplexed.
Also encouraging to read that the 30w radios will run 100% at 20w with the
smaller heatsink. That's probably all the power I'd need in my application.
73,
Paul, AE4KR

Ken,
Correct, of course, but I'm assuming that in a 30w PA, smaller components
not somehow directly sunk to the main chassis heatsink will reach their max
operating temps in a very few seconds of key-down, and therefore have to be
spec'd the same for intermittent duty PAs as if they would if they were in
continuous duty.
<---There are several components that are "common failures" in Mitreks used
in duty cycle apps greater than it was designed for.
