Notes: This station signed on as a rock station in September 1976. Many challengers have come and gone over the years, challenging KATT in the classic rock arena and in modern/alternative rock. However, KATT-FM has endured each challenge. Initially, Rock 100 The KATT, the station added the “.5” in the early 1990s.
In 1980, KATT (AM) (1140 AM; now KRMP) was added to simulcast, giving the station an FM suffix to its call letters (KATT-FM) In 2007, the station downgraded from a Class C FM station to Class C1, going from 97 kw to 29 kw, part of a series of moves by multiple stations in the state to help sister station WWLS-FM change frequencies (from 97.9 to 98.1) and upgrade it signal. Despite the lower power, the station covers the metro without any difficulty.
The station’s iconic “cat” logo has also proved to popular, making bumper stickers and apparel with the logo sought-after collectibles.
