Cecil,

You saw my simulations of your example. I got an SWR of 66.3 for ZS=0 and
69.1 for ZS= j400. That is as close as I can resolve. I had thought that if
it was going to change, I would get an SWR of 1:1 for the conjugate matched
case. What I had neglected, and maybe you also, is the fact that when you
connect an SWR meter into the middle of a resonant series tuned circuit, the
current is 90 degrees out of phase with the voltage.

It seems fair to say that if the source impedance

has anything to do with rho.

Chipman seems to say that an SWR meter can be disturbed by a localized
energy
exchange between reactive values with opposite signs. The impedance of the
source has an effect upon where in the transmission line those localized
energy exchanges occur.
