no .. signal strength is a more significant problem with AM, the audio
signal is based on the amplitude envelope of the carrier signal, while
in FM the frequency of the carrier signal is varied according to the
audio, and the receiver follows that. That is of course a
simplification, but they are quite different.
Cool, thanks for clarifying that.
