CKKW-FM is a Canadian radio station licensed to Kitchener, Ontario, with studios located in Waterloo broadcasting at 99.5 FM. The station is owned by Bell Media and airs a classic hits format branded on-air as KFUN 99.5.
The station originally began broadcasting in 1959 at 1320 AM, until it moved to 1090 AM in 1975.
In February 1984, CKKW began AM-stereo broadcasting with a Motorola C-Quam format.
Originally owned by Carl Pollock and later becoming a subsidiary of his company Electrohome, CHUM Limited acquired CKKW in 1993, and shortly thereafter instated the oldies format and "Oldies 1090" branding. This was maintained until 2009, except for a brief period from 2001 to 2002 when it was part of CHUM's short-lived sports radio network, The Team.
On April 10, 2008, CKKW applied to the Canadian Radio-television and Telecommunications Commission to convert the station from the AM band to the FM band at 99.5 MHz. The application indicated that CKKW will keep its present oldies format on FM. The application was approved on October 3, 2008.
