and everything seemed ok. After dinner I turned the K3 on and it would not

Mike,
The K2 maximum output power on 10 meters varies due to component
tolerances and care taken during construction. Since you have
apparently done the normal things to improve it, and the power is still
low, it may be time to consider component tolerances - primarily for the
Q5 and Q6
Nice !!! Ditto.

I can't think of an easy answer - mainly because many or the parameters

Please explain what you mean by waterfall display is super messed up -
the K3 defaults to a 400 Hz width for DATA A and that would show a

No.
Since the regulator is a low drop out, the ideal voltage would be about a volt
over the minimum input for the regulator. That keeps the dissipation at the
lowest level inside the radio. Of course the Tx is another issue.
