The only really accurate watt meter, which won't help us totals at
all, is the Byrd.
This is especially true at vhf/uhf frequencies.
The Wave Node system may come close to the Byrd, but I don't know the
specs on it.
The RF Applications meter with the CW output isn't too bad, but it too
is not a Byrd meter.
The indication provided by all other watt meters, accessible or
otherwise, should be viewed as relative.
While this may be a bit disappointing, remember that a relative
reading can also tell you when you are having trouble such as Tom
recently experienced with his 590.
As for the readings from the meter inside the radio, this meter is
reading on the radio side of the tuner. Any external meter, when used
along with an antenna tuner that is internal to the radio, is reading
the natural SWR of the antenna, and the power after the insertion loss
of the tuner.
