Mister howardm, the 540 frequency from Tijuana is now Spanish-language talk. The 1260 frequency, which is located in Mission Hills but licensed to the ritzier-sounding Beverly
Hills, is classical KMZT, "K-Mozart." On March 23, 2002, the old KGIL became KSUR, "The Surf," and aired an adult standards format, simulcasting with XESUR-540. (The first day was all Nat "King" Cole and the second day was all Frank Sinatra.) In 2004-05, the stations were known as "Oldies 1260 & 540" and had a 1500-song playlist covering 1954 through 1963. In 2006, the 1260 frequency became "Go Country" KKGO. A year later the country format was moved to 105.1 and the KMZT call letters and classical format were moved to 1260. For a short time in 2009, 1260 reverted to the original KGIL call letters and had a talk format, then switched to a mix of pop oldies and adult standards as "Retro 1260" before returning to the KMZT call letters and classical format. I trust all this is perfectly clear.
