Cecil,

Are you suggesting that a steam engine is needed in addition to "obvious
and elementary notions"?

Let's see, how about a nice triple expansion engine fed from a Scotch
boiler fueled with the finest Welsh coal. Don't forget to raise steam
slowly, and make sure you don't tie down the safety valve.

Why the vast amount of palaver and bickering about such an obvious and
elementary notion defeats the imagination.


Reg, you are in a room with a transmission line passing through it.
You measure all voltages, currents, and powers. How do use your "obvious
and elementary notions" to tell if the transmission line is conjugately
matched or not? How do you measure the impedance looking toward a typical
amateur radio transmitter without changing the very thing you are trying
to measure? Many have tried and many have failed.
