AM can have as good a fidelity as FM and in narrower occupied bandwidth. Consider the requirements for FM stereo and the fact that the L-R channel is AM. Yes, it's DSSBSC, but AM non the less. I will agree with the (unfortunate) AM noise issues in the real world when it comes to AM reception, but that doesn't alter the facts. As far as AM transmitters - Have you ever proofed an old Raytheon RA 250 or 1000? Amazing transmitters. RCA BTA-5F's were also pretty good, once you remove the splatter filter, which wasn't necessary with a decent processors.
