Actually, what I am attempting to do is discourage your lumped-circuit
religion, where a 100 uH, 10" long coil, can propagate an RF signal in
3 ns, and move you guys closer to the reality of Maxwell's equations.

Hello Cecil,

I am not addicted to "lumped circuits", I just use the appropriate
model. Many amateurs built and / or designed their own HF PA (and
other circuitry relevant to the hobby). Do you really think that they
all considered every component to be a transmission line?

Transmission lines in general.
I agree with Tom, "Transmission line approach" is also just a model
with limited validity. It all depends on the Engineer/Designer whether
to use it or misuse it.
