KPDQ first signed on the air on July 30, 1947; 77 years ago (1947-07-30).[4] It was owned by George W. Davis, who also served as president. For its first four decades on the air, KPDQ was a daytimer, powered at 1,000 watts but required to go off the air at sunset. The station specialized in religious programming.
In 1961, KPDQ added an FM station, KPDQ-FM, originally at 93.7 MHz.[5] At first, it was a simulcast of KPDQ, but began separate religious programming by the end of the 1960s. In the 1980s, Davis' son, George Davis II, became the president of the Inspirational Broadcasting Corporation, the new name for the company that owned both stations.
In August 1986, Inspirational Broadcasting sold KPDQ-AM-FM to Salem Media.[6] Shortly after the purchase, Salem Media got permission from the Federal Communications Commission (FCC) to broadcast around the clock on KPDQ, with reduced nighttime power at 500 watts.[7] Salem also added an FM translator in the mid-2010s, for listeners who prefer FM radio.
