810 AM is a United States clear-channel frequency, on which KGO in San Francisco, California and WGY in Schenectady, New York share Class A status.
In 1969, the station was bought by Southwestern Broadcasters, which switched the call sign to KBRN and the format to Christian radio.
[4] In 1982, the station was acquired by Interstate Broadcasting Systems (who owned KYMS in Santa Ana at the time), which changed the call letters to KLTT (coupled with adopting the 80 K-Light moniker) but continued the religious format.
[5] Crawford moved the KLTT call sign and religious format to AM 670, a station which transmits with 50,000 watts in the daytime, compared to AM 800's 1,000-watt signal.
[7] In October 2016, KLVZ, whose gospel format had moved to AM 1220 KLDC in April, returned to the air with Pop Classics, a mixture of adult standards and oldies from the 50's, 60's and 70's.
[8] On April 13, 2020, KLVZ added a new simulcast translator on 95.3 FM (K237GG) to help boost the station's signal into downtown Denver.
