The disagreement is entirely about the interpretation - in other words,
it's about the theory about standing and travelling waves. Richard
habitually misses out this step, which makes it look as if the Bird
wattmeter "proves" the physical existence of forward and reverse
travelling waves of power.

It doesn't. Everything that you see printed on the Bird's meter scale,
and in the Bird literature, represents that company's particular
interpretation of theory about waves on transmission lines. The details
of that theory are *not* agreed within this newsgroup, which means that
- to some people - the two halves of Richard's claim do not join up.


Ian, I've not detected this particular disagreement about waves on
transmission lines in the group. I would be most grateful to see a brief
statement of where and how Bird's interpretation of theory is found infirm.
