In the brief period of broadcast stereo before FM multiplex stereo,
often one channel is carried on AM and the other on FM. I borrowed
one of those receivers in my college days and the AM performance was
astounding. Brenda Ann is right: Most AM receiver designs today
simply ignore fidelity as an issue.
That's the FCC's fault. There are too many stations and the
bandwidths (both transmit and receive) have to be narrow or the
splatter would drive the few remaining nut jobs that still listen to
AM away.
