KCHAT is a celebrity talk radio station in GTA Vice City hosted by Amy Sheckenhausen (voiced by Leyna Weber).
Sheckenhausen is a ditzy girl with a cheery voice, who tends to gush over her famous guests while ignoring those she tends to find boring. She sometimes reads a book during interviews and forgets when there's a commercial playing. When a commercial finishes, she starts the show by saying "Hello, welcome back to KCHAT. I'm a woman!"
Of the nine radio stations in the game, KCHAT is one of the two stations not represented in the Grand Theft Auto: Vice City soundtrack CD.
