JJ,
500 / 1000 = 50%

That is not correct. To 100% modulate an rf carrier the audio
power must equal 50% of the unmodulated carrier power. It takes 50
watts of audio to 100% modulate 100 watts of carrier. This is
assuming high level modulation where the audio is applied to the
output stage. At 100% modulation power is increased 1.5 times the
unmodulated carrier power. So for 100 watts with 100% modulation,
the output would be 150 watts, with 100 watts in the carrier and
25 watts in each sideband. Get a book and look it up.
