The original KFWB studios and transmitter location were at the Warner Bros. Studios, which is now KTLA, at 5800 Sunset Boulevard. One of the two original towers still stands prominently out front. Due to RF interference getting into the movie studio's "talkies" sound equipment, the transmitter was moved in 1928 to the roof of the Warner Theater, now the Hollywood Pacific Theatre, at 6423 Hollywood Blvd. Eventually the studios were also moved to the Warner Theater. Those two towers are still standing.
