How about frequency respoonse?


Of what? AMS radios have nearly identical freqeuncy response to FM radios.
Noise being the primary drawback... and even that isn't an issue in a high
signal area such as a large city. Back in the heyday of AMS, I used to
actually prefer to listen to KGW-AM over any of our local FM stations
because the signal was strong and clean and every bit as good sounding as
FMS, with the added advantage of not having to deal with multipath or picket
fencing. FM does have the advantage in distance over AMS for clean signal,
but only because of the reason William brought up.. limiting. You can
amplify an FM signal far beyond clipping without affecting the intelligence
contained therein. I don't believe early FM receivers had any designed-in
limiting, they just didn't have any gain.
