KPRO radio signs off ending 61-year run
RIVERSIDE – (INT) – Radio station KPRO (1570AM) has fallen silent and its owners say it will not return to the air.

The station debuted in 1957 with daytime-only broadcasts identifying itself as K-ACE with offices, studios and 4-tower transmitter site in the city’s Casa Blanca district.

The station changed formats and call letters several times eventually convincing the FCC in 1986 to use KPRO, the original station at 1440AM that signed on in 1941 and also went silent in the 1980’s only to come back under new ownership with Spanish-language programming and call letters of KDIF.

KPRO billed itself as 'Inspirational Radio' offering Christian programming for the past several years, and at one time, Dodger baseball.

In a 2015 license renewal application, the FCC cited debts owed to the Commission.

Owners of the reincarnated KPRO have sold the station’s site. Transmitter towers have fallen and the offices and studios will be bulldozed to make way for a condominium development. Its demise comes as AM radio struggles to survive a decline in ratings and revenue in the Riverside-San Bernardino-Ontario radio market. The real estate that many of the remaining AM stations occupy are worth more than their licenses and broadcast facilities.
