Hi Don and everyone.
It does seem that calibrating a wattmeter is a hard thing to do if you don't
have an office at NIST! When I care about accuracy, I measure RF voltage
with the Elecraft DL1 and hope for the best.
Suppose you have a good DC standard, such as Don's or Joe Geller's designs.
Is there anyway to bootstrap accurate RF voltage measurements from accurate
DC measurements?
It's true that measuring power at +/- 20% is plenty good if what we care
about is signal strength on the other end of a QSO. Still, it would be
useful and satisfying to be able to measure RF voltages more accurately when
doing experiments.
Thanks and 73,
Ken
