I cannot find my reference just now, and perhaps the radio buffs out
there can clarify.  Although FM broadcast channels are spaced 200KHz
apart(which is obvious just looking at the dial)  there exist in that
channel guard bands, pilot signals, and subbands.  I believe(and if anyone
out there knows differently they are welcome to correct me) that the
actual audio portion of the main FM band takes up around 160 KHz.
