But only if you are measuring peak envelope power. Other wise, the other means of measuring power have just as much validity. If you like 'big numbers', using Pep is sure the way to do it. If you don't know what those numbers mean, you really aren't saying anything important or significant at all. What's the difference between about 700 watts Avg/RMS, and 1000 watts Pep? Absolutely nothing.

(Ask him, he'll say the same thing if he's honest about it.) I doubt that very much.Seeing as bob is well aware of what AVG power actually means and how it is measured.
There is no such thing as RMS power.
For Amplitude Modulated signals at 100% modulation:
PEP is 2.66 times AVG 100% modulated power or 4 times unmodulated carrier power.
therefore a signal of 1000w PEP would be equivalent to a 250w AVG power unmodulated carrier or a 375 watt AVG 100% modulated signal.
A huge difference between either modulated or unmodulated AVG power and your 700w AVG/RMS power.
