Can someone explain the math behind the "375" watts AM being 1500 watts pep ( pep = 4x am power)? I know it been a while since I was in engineering school but, as I remember it... at 100% modulation, sidebands were 25% of the carrier power each for a total of 50% peak. so at 100% modulation, with 1000W carrier + 500W peak for the sidebands = 1500W Also, AM isn't measured in PEP anyway... where am i wrong? How is the carrier different from CW power, and how are the sidebands different from SSB peak power? I just don't get this 4X thing at all. I know there's something I am missing, there must be.
