Two, if you use asymmetrical modulation you will sound like a R&R
radio station (audible distortion) and you will be supplying more than
1 kW of input power to the final amplifier.

I have heard much about new peak reading power meters manufactured
for HAM radio use that are very accurate with any modulation if any
and the very good scope is still accurate. That is way I bought mine.
