If that's not impedance matching, I don't know what it is! (Oh, "Load line"

And there's the catch. If the load line is the source
impedance, the load (not the designer) effects the source
impedance.

Apparently, I'm not following the same conversation here, because I
thought that the impedance matching network (in the instant example, the
pi-net output of the transmitter) was what translated the load impedance
to the source impedance, matching both in the process.

Maybe I inferred wrong. From your "load line equals
impedance" statement above, I inferred that you were
implying that the load line *is* the source impedance.
