Keith's 70.7V/50 ohm source----50 ohm 1/4WL stub----short

A Bird wattmeter reads 100 watts forward and 100w reflected. The
current in the source is zero. The source is not only not sourcing any
forward power, it is also not sinking any reflected power.

What complete and utter Texas-size bullsh*t. It's obvious that the
source is sourcing the forward voltage wave, and it's sucking up
entire reverse voltage wave from the line.

But the propagating waves of average power envisioned by Cecil and some
others, which they measure with their Bird wattmeters, don't follow the
same rules as voltage waves. Unlike voltage waves, which are very well
known and subject to over a century of analysis using well established
mathematics and physical principles, the waves of average power follow
rules which constantly change to suit the needs of the moment. Watterson
fans will recognize the rules for propagating power waves as closely
resembling those of Calvinball.
