Phil's comments about this recommendation being rig specific is right on the
money. That kind of general blanket statement is very
misleading, in the same way the PSK setting guidelines of no ALC = quality is
really rig specific.
Yaesu's official recommendation (at least what they publish in the manuals) is
to run at reduced power if the transmission lasts
"for more than a few minutes." I never could understand that - but since I
mostly contest or DX chase on RTTY, I don't send long
transmissions. Never had a problem with the 2K or 5K. Maybe I'm just living
lucky?

I guess that is a good general rule, but it does NOT apply to ALL radios!
When I used an IC756 and then an IC756Pro, I ran them at 100 watts in almost
all contests.
They never got hot, and never faltered at all. I believe they were designed
to run flat out on RTTY, so it was not a problem.
That is not the case for many Yaesu rigs though, which do need to be run at
half-power.
I now have an IC7800, and I run that at half-power, not because it can't
handle the full 200 watts, but mainly because I don't need to run it flat
out, but also because many contests have a low power section which is
limited to 100 watts.
