KNSN transmits with a power of 550 watts, day and night, with its transmitter off Newton Avenue in San Diego, at the intersection of Route 15 and Interstate 5.[4] KNSN shares the tower with KURS (1040 AM). Programming on KNSN is also heard on 15-watt FMtranslator stationK277DG at 103.3 MHz in San Diego.[5]
History
The station signed on in 1947 as KSON.[6]
KSON used a 250-watt RCA transmitter with a tower that was 250 feet tall. The station was owned and operated by Fred Rebal.
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.
On May 22, 2014, Crawford Broadcasting announced it would acquire KNSN for $1.5 million through licensee Kiertron, Inc.[10] The sale was consummated on July 25, 2014, with the Spanish
Christian programming shifting to 1040 KURS.[11] KNSN went silent in late July 2014 in preparation for a new format under Crawford Broadcasting ownership. KNSN returned to air on September 29, 2014. The format ended up being the previous religious format, this time in English. It is mostly a simulcast of co-owned KBRT in Costa Mesa.
In 2017, a 15-watt FMtranslator station was added, 103.3 MHz K277DG. It shares the same broadcast tower as the AM signal. The translator is often cut off as distant station KRUZ in Santa Barbara, the dominant station at 103.3, often hashes out K277DG's signal in tropospheric ducting.
