From the 1975 NAB Engineering Handbook (which in turn directly excerpted it from the FCC regulations)..
In Hawaii, the 98-108MHz band is allocated for nonbroadcast use. The FM band is 88.1-97.9.
In Alaska, the 88-100MHz band is allocated to government radio services and non-government fixed service. The FM band is 100.1-107.9.
In Alaska and Hawaii, 76-88MHz are allocated for non-broadcast use. Channels 5 and 6 are not available for use by TV stations.
Obviously all of those restrictions have long since been eliminated. As was an adjacent footnote reserving 89.1 in NYC for use by the United Nations.
