Joel,
Then that puzzles me even more !
If you made a change to the line and then adjusted the single tuner at
the load end, the impedance terminating the line changed. If the
terminating impedance changed and the line remained matched, the load
seen by the generator changed. If the load seen by the generator changed
then so did the power it delivered to the system.
That suggests that some of the level change measured on the
microvoltmeter might have been due to variation in generator output
rather than changes in line loss. It seems to me that another tuner at
the source end would be essential to ensure that the generator always
"sees" 50Ohms, and always delivers the same power to the line.
Or did I misunderstand something?

Steve,
I stand corrected, my memory is good but short<g>. I went back and looked
at the article. The single tuner was at the far end. That did make it easier
to adjust it while looking at the uW meter. At maximum output, it still
reflected an impedance back to the generator that provided maximum output.
