Grandfathered Super-power FM Stations

The following long-established stations have grandfathered licenses to operate at a higher power than the usual limit of 100 kW. (Note that this is distinct from stations which cover a large area by virtue of being up high; these stations actually operate at the listed powers.) The format is the same as for regular FM stations.

(*)CKOI actually is not a grandfathered station, but the result of a typographical error at the CRTC.
(**)We think at least one of these is a data-entry error in the FCC database, and does not represent a real station.
