Yes, at least three of them:
1. Is the operation as I described legal?
Or, how much power is actually being radiated,
about 1500 watts or about 1800 watts?
2. Where does the reflected power go, back up the line and radiated,
as when a tuner is used to "match" impedances, or to be
dissipated in the amp's apparent "generating" resistance?
Which condition is true?
3. Are the indicated numbers I read valid? Since the 50 ohm
measuring tool is not in a matched 50 ohm system. Both Bird
and RF Applications state their units are to be used in 50 ohm
systems. Or, if the indicated vswr is greatly different than 1:1,
are the power, voltage, etc. numbers measured by the device
accurate? The indicated impedance at my measurement
insertion line point (per the MFJ-259B) is R=20 or 21, X=10 or 11,
swr = 2.3 indicated, same as read by the P-3000 at linear power,
see earlier post.
Those are the questions, directly or implied in my post.
