I'm not sure what this means. Modeling output networks is pretty
straightforward; even modeling the output amplifier is not terribly
difficult. Getting an idea about the spectral purity of a given
transmitter is not difficult.
Of course, a wavemeter (i.e., a tuned wattmeter) is extremely
valuable to investigate harmonic energy. DeMaw describes this
in Solid State Design, as I recall.
