History

KRDU signed on the air on December 26, 1948, at 1130 kilocycles.^[2] It was owned by the Radio Dinuba Company with studios on L Street. The call sign represents Radio DinUba. At first it was a daytimer, required to go off the air at night and powered at only 250 watts. In 1949, it moved to 1240 kHz with 250 watts full-time.

In 1961, it moved back to 1130 kHz with full-time authorization, powered at 1,000 watts around the clock.^[3] In 1975, it added an FM station, KLTA (now KSOF, still co-owned with KRDU).

In the 1990s, the power was increased to its current 5,000 watts days and 6,200 watts nights. In 1999, KRDU was acquired by AMFM, Inc.^[4] AMFM was acquired by Clear Channel Communications, which later changed its name to iHeartMedia.
