Bill,
That is EXACTLY the point and why the purists prefer "true" FSK. True
FSK will not give you the "unwanted sidebands" and bogus signals all up
and down the band you refer to above. If you do hear these ghost
signals, you can bet the farm they are NOT running true FSK, but rather
are running maladjusted AFSK...

P.S.
Another way to tell someone is running AFSK without a clue is when they
plug the AFSK tones into an auxiliary jack and forget to disable the
mike. You them hear over the air, "Mabel, bring me another coffee..."
