This might be a case of a station that suffered by not moving to FM. Now it’s too late. KFI might not be around in a few (2 or 3 years). It was nothing for Audacy to axe WCBS.
What IHeart could do with KFI is put BIN (the Black Information Network) on it. If I remember correctly, Los Angeles has a fairly good-sized African-american population and KFI's signal reach could take in the same base from San Diego to Palm Springs...
The only real problem I see with that is Riverside's KPRO which already carries the format for the Riverside and San Bernardino areas. If KFI were to take up this format, IHeart would have to 1) find another format for KPRO; 2) sell KPRO; or 3) cancel KPRO's license.
