I can't offer any confirmation that there is such a regulation, but I
can think of a possible rationale for it: AM radio is subject to
jamming, even by transmitters located outside the US, whereas FM is less
susceptible to intentional interference from distant sources.
Now, whether the national-security justification be legitimate or not, I
suspect that Washington's real purpose in instituting such a rule was to
promote the commercial development of FM radio.
