Without switching personalities, format or any of the other essentials that normally go with such things, KMPC-FM (101.9) will cease to exist today and reemerge as KEDG-FM. “Nothing will change except for the advertising and promotion,” says Denise Maynard, programming assistant for “The Edge” (as the station now calls itself). She said the call letter change came about because station management believed listeners confused KMPC-FM, an album rock format, with its AM sister station which programs big band and easy listening music along with the California Angels baseball games.
