What is the radio frequency of KACL?

The fictional radio station KACL in Frasier broadcasts at 780 AM.

KACL is the Seattle station where Frasier Crane hosts The Dr. Frasier Crane Show. The station is one of the series' most important recurring locations, even though viewers usually experience it through the studio and the characters' conversations rather than through exterior scenes. Frasier's job at KACL drives many storylines involving callers, coworkers, ratings, and station management.

The station's staff includes producer Roz Doyle, sports broadcaster Bob "Bulldog" Briscoe, restaurant critic Gil Chesterton, and station manager Kenny Daly. Their contrasting personalities create a workplace ensemble that complements the Crane family's stories at home.

KACL is fictional, but its call-sign-and-frequency presentation follows the conventions of American radio. The number is commonly spoken in the series as "KACL 780," while the quiz answer is conventionally written as 780 AM. It should not be confused with real-world stations that may use similar call letters or with nearby AM frequencies such as 770, 790, or 810.
