Something you're missing, Wes. The 100W amp doesn't kick in until you
ask for more than about 14W. So at 11-12W, you're seeing the IMD of the
QRP exciter stage running near it's maximum power.
I'm wondering if it might be practical to modify the control software so
that the 100W amp kicks in at lower power levels. Are there other
consequences? Wayne?

Something else to note, even at 14V, running a K3 at 11-12 watts is a
disaster.
