Oh God...Earth to Len....harmonics *are* phase shifted. If you reduce the

I'm not sure where you get this "phase shift reduction to zero" but it
isn't quite like that. Sigh. Read following -

OK, let's get down to basics. From "Electronic Designers' Handbook,"
by Robert W. Landee, Donovan C. Davis, Albert P. Albrecht, 1957,
McGraw-Hill Book Co., Chapter 5, here's the instantaneous voltage
at any point in time of an AM RF waveform:

e(t) = E [1+M Cos(omega_m t)] Sin (omega_c t)

Rest deleted. Interesting refresher, but not related to Amater
Radio POLICY, a subject which you, Sir Putzmaster, have been pushing
down others throats lately.

Not that I expected anything different from you. You can't help
yourself.
