KCBQ uses a directional antenna at all times. KCBQ used a Top 40 format in the 1950s, 1960s and 1970s, later airing country music and oldies formats in the 1980s and 1990s, before switching to talk.

Edgemoor was part of a Spanish land grant to Maria Antonio Estudillo who married Miguel de Pedrorena, a native of Madrid. By the 1850s, through a variety of ways, individuals obtained portions of the grant and began to farm. Walter Hamlin Dupee purchased Edgemoor Farm in 1913 and built it into a national award-winning dairy farm, polo pony ranch and early tourist attraction. Such was his prominence that the Guernsey Breeders Association in 1921 called his place "the foremost authority and breeder in the U.S.", having given the most grand champions at this ranch founded by John and Walter Dupee. Dupee said, "I am interested in pure breeding stock, modern equipment, and scientific methods, which I place at the disposal of all dairymen". A series of personal setbacks and problems brought Dupee to sell Edgemoor to Godfrey L. Strobeck.
