understand why it is REQUIRED. It would be NICE to be able to drive it
to rated power from a barefoot K3/10 (or K2/10), but that could push the
driver to the point where it produces a bit more IM and THD (that is,
splatter and harmonics). That's the main reason that firmware for the
K3/100 now limits output power to 110 watts.

The Elecraft design engineers are quite sharp, and have carefully
thought quite things like this. As a result of my own EE background and
ongoing conversations with one of them who is a neighbor (and a serious
contester), I'm firmly convinced that they have made a very intelligent
set of design decisions about these issues. The last thing our ham bands
need is more loud lids spewing trash.
