KNSN (1240 kHz, "K-Brite") is an AM radio station licensed to San Diego, California, United States. The station is owned by Donald Crawford's Crawford Broadcasting, through licensee Kiertron, Inc. It airs a brokered Christian radio format, mostly simulcast with co-owned AM 740 KBRT in Costa Mesa. Programs include half-hour weekday shows from Charles Stanley, Joyce Meyer and David Jeremiah. Studios for KBRT and KNSN are on Airway Avenue in Costa Mesa.[2]

KNSN is powered at 550 watts, day and night, with its transmitter off Newton Avenue in San Diego, at the intersection of Route 15 and Interstate 5.[3] It shares that tower with AM 1040 KURS. Programming on KNSN is also heard on 15 watt FM translator station K277DG at 103.3 MHz in San Diego.[4]

The station signed on in 1947 as KSON.[5] KSON used a 250-watt RCA transmitter with a tower that was 250 feet tall. The station was owned and operated by Fred Rebal.

Through the 1960s, 70s and 80s, KSON was a country music station, mostly simulcast with 97.3 KSON-FM, now heard on 103.7 MHz. In 1985, KSON-AM-FM were acquired by Jefferson Pilot Broadcasting. On July 24, 1996, the AM station's format was changed to children's radio, as KDDZ, with the call sign standing for "Kids."[6] It started as a KidStar Radio Network affiliate. But that network was short-lived and merged with Radio Disney.

During a heavy rain and wind storm near the end of December 2004, approximately half of the radio antenna tower collapsed and fell, leaving the tower at a height of about 200 feet. It had been 442 feet tall.

Later, KNSN was a gospel music radio station, having that format from January 2007 until July 2007. The station was sold to Multicultural Broadcasting Inc., owned by Arthur Liu, on June 1, 2009.[7][8] In the early 2000s, it shifted to a Spanish-language Christian radio format.

On May 22, 2014, Crawford Broadcasting announced it would acquire KNSN for $1.5 million through licensee Kiertron, Inc.[9] The sale was consummated on July 25, 2014, with the Spanish Christian programming shifting to 1040 KURS.[10] KNSN went silent in late-July 2014 in preparation for a new format under Crawford Broadcasting ownership. KNSN signed on again on September 29, 2014, largely as a simulcast of co-owned AM 740 KBRT in Costa Mesa, California.

In 2017, a 15 watt FM translator station was added, 103.3 MHz K277DG. It shares the same broadcast tower as the AM signal.
