The mythical lurkers should note all the effort that goes into a
perversion of a vastly simpler exercise that could be conducted easily
at the bench; and the reason for not going to the bench? Some infer
too hard (by lack of effort); others explicitly state it doesn't
matter (through reams of virtual pages gusting on about its
inconsequence); and yet others deferring it with excuses it demands
too much time for the effort.


Richard,

A simulation of a circuit is better than the "bench". I have components with
0% tolerance, 0 length leads, no parasitic components, and no power limits.
It does precisely what a physical meter is a compromise of.

It does not care whether there is a piece of coax connected to the circuit
or not. Neither does the physical meter. Both find SWR by calculating the
deviation of the load impedance from 50 Ohms.

And, consequently, the results you get should be exactly the same as
those of us using equations rather than modeling simulations get. I
don't see any reason why people who don't believe the equations would
believe simulation results.
