You are hearing the effects of the sidebands, not the Carrier.


DUH! And, you only have the sidebands as a result of the
carrier/modulation ...


So what? You implied or inferred that what was heard from the FM radio was
caused by the AM Carrier. Leave out the Carrier and you will hear the same
thing.


In a properly designed transmitter the Carrier amplitude does not change
with modulation. I have better tools than FM receivers to prove that fact
and theory agree for AM.


And the time to argue the insignificant ... sharpen that razor blade,
you can then successfully split much narrower hairs ...


It is important that we not confuse a person new to electronics by the type
of inane points you make. It doesn't matter a whit if someone's AM
transmitter Carrier shifts on power peaks due to poor regulation. It has
nothing to do with "AM" and everything to do with poor design.

Side issues don't help the new folks.
