I asked a couple of weeks ago (and never got a reply) what the key-down
rating for the K3/10 is. I know it's 10 minutes at 100W for the K3/100, but
the 10W PA doesn't necessarily have to be developing full power at 100W out,
so it seems incorrect to just assume that 10W is okay.

I never liked to use more than 5W out of my K2/10 for continuous duty modes
as even at that power it got pretty warm underneath after 3 or 4 minutes,
and the K3 doesn't seem to be much different in that department. With the FM
capability it would be nice to be confident what power level is OK.
