What are the call letters of the radio station?

The radio station’s call letters are KACL. In Frasier, KACL is the fictional Seattle AM station where Frasier Crane hosts his call-in psychiatry program.

The station is central to the show’s workplace stories. Frasier broadcasts from KACL alongside producer Roz Doyle, while other station personalities include sports host Bob “Bulldog” Briscoe, restaurant critic Gil Chesterton, and station manager Kenny Daly. The fictional station’s frequency is identified in the series as 780 AM.

KACL is not the same as a real Seattle station, and its call letters are easy to confuse with the fictional or real-world call signs of other broadcasters. The name also has a behind-the-scenes connection: it is commonly explained as combining the initials of creators David Angell, Peter Casey, and David Lee, with “K” fitting the convention associated with stations west of the Mississippi River. The letters also resemble the word “cackle,” fitting the comedy setting.
