Hey Whitey... last week this time, we were sitting at The Deerhead on Clinton Street having some Beef On Weck and trading classic radio stories about Ampex 440-C's, Gates turntables, formatics, WBBF, WAXC and radio Elmira-Corning, Rochester and Buffalo. Definitely good times.
"Sherlock" is way too modest to admit it, but you guys (and ladies) have an outstanding talent with his contributions to this board.
To address your question, the "non-com" band starts at 88.1 (Channel 201) and goes through 91.9 (Channel 220), according to the FCC
Table of Assignments.
Channels 201-220 are more aptly defined as "non-commercial" rather than "educational," which explains the interesting array of stations, from religious non-profits to colleges to community owned stations, that can be found operating in that part of the FM band.
Now, in Canada, the frequencies between Channels 201-220 are fair game to commercial operators, which makes the FM band pretty interesting in this neck of the woods with big ol' 50 kW flame throwers playing everything from commercial classical, commercial jazz and adult hits.
It's one of the most congested FM bands in the country, shared by two nations, which is why space is at a premium, and there are few, if any LPFM's for knuckleheads like me.
Hope this helps.
