I could use a little clarification on the difference between SSB and AM as far as frequency shift is concerned.

As I understand it the reason you have a clarifier for SSB but not on most AM only radios is because on SSB the "carrier" is provided by the receiver, as such the carrier frequency and the received signal are from two different sources and need to be matched together to properly demodulate the signal. With AM though the carrier comes in with the signal so both the carrier frequency and the sidebands are from the same source, as such as long as the signal is within the passband of the filters the receiver can demodulate it. If this is true it would seem to me as though small shifts/drifts in frequency shouldn't really effect AM at all.

Am I off base in thinking that the OP has nothing to worry about on AM or do I need to go back to school myself?

PS: a couple of the posts above mine seemed to indirectly touch on this so I thought this question would be relevant to the topic and probably helpful to the OP.
