"Henry Kolesnik"
HiFi AM is stretching the definition of HiFi!
** Not in the slightest - at least as as far as the receiver is
concerned. A flat response from 20Hz to 15 kHz +/- 1 dB with low THD (
0.5% or less) and low background noise is a genuine "hi-fi" signal -
better by far than the reproduction from a typical cassette deck which is
riddled with audible defects AM does not have.
Designing and building a good receiver is not a trivial task.
** A receiver capable of recovering the transmitted audio signal faithfully
is not very difficult - many amateurs have successfully built them.
The inhibitions to hi-fi that most associate with the AM band are not
inherent in AM as a technique.
