Compressing the audio will not increase range
in an FM Xmiter, but it will make you sound louder.
FM Rock radio stations do it all the time.

They are not trying to fit their transmission within a
10KHz channel spacing, they have far more bandwidth
to play with.

Also, it's not the only trick used. Something much more
basic is used to extend the range of an FM broadcast.
