If you believe by your understanding of the clips you quoted from
Mendenhall that a conventional, single vacuum tube Class C r-f
amplifier provides a functional termination of 50+j0 ohms for energy
applied to the output connector of the transmitter, then please
explain why that termination allows such signals to reach the plate of
the PA tube -- whose non-linear characteristics created the
_measured_ r-f intermodulation products and other performance data
given in the Mendenhall paper I quoted.
