KECR or Family Radio is the San Diego Family Radio affiliate. It has been on the AM band since the mid-1990s, at 910 kHz. It previously broadcast on 93.3 FM (now KHTS-FM). The studio and the transmitter site is near Moreno Avenue, north of Lakeside, California by Highway 67.
The transmitter site is also the broadcast home of KCBQ/1170. They share the seven-tower site.
During the October 2003 Cedar Fires, part of KECR's rural transmitter site was destroyed by flames. Only one antenna (out of a total of seven) and an 'electrical doghouse' were completely destroyed. The station has been fully upgraded and repaired.
In the 1960s the station was a Top 40 rocker known as KDEO, with the moniker "Radio Kay-dee-oh". The station was also the first in the world to broadcast the countdown program American Top 40, on July 3, 1970.
In the mid-1970s the station was KMJC, Magic 91, still playing Top 40. In 1980 KMJC flipped to Christian programming and changed their call's meaning to "King and Master, Jesus Christ". In 1995, KECR-FM and KMJC began simulcasting. This ended in 1996, when Jacor took control of the FM station.
