Dick,
It is easier on the K3 to tune at 15 or 20 watts.
Reason -- at 10 watts, only the low power PA is active and it will be
operating near the upper end of its range.
Increasing the power activates the 100 watt amp and at 15 or 20 watts,
everything is loafing along at much less than its full output.

I want to verify my understanding. In the interest of protecting the output
transistor(s) against a mishap in one's antenna system, would it be better to
tune at 10 watts (finals off) or at 15 watts (finals on)?
Or is the driver so well protected that it doesn't matter?
