OK, Richard, is impedance 18 - j8 ohms sufficient?

Hi Walt,

It is more direct and responsive to every request I've made for
anything from anyone else so far. However, I presume it is the value
at the antenna connections of the amplifier that transforms through
the plate tuning toward the plate itself to render something more like
Rp (several KOhms?). Is it from a direct measurement, or by inference
to the load and tuning adjustments?
