Hi James,
You're chasing your tail, me thinks ...
I'm a retired career two-way radio tech and a
fan of Bird meters, thought by many to be the
best in their price class, and they're rated at
+/- 5% of full scale ... if they're calibrated to a
lab standard ... which in itself isn't likely to be
much better. Even two "identical" elements will
differ in the readings they produce.
Accurate RF power measurement is difficult
under the best of circumstances.
I have several Birds, a Bird dummy load, a W1
and a W2 and I'm satisfied that the W1 and W2
are pretty good. "Pretty good" is about as good
as it gets for us ordinary folks. (:-)
73!
