KYYS (1250 AM) is a radio station broadcasting a Regional Mexican format. The station, licensed to Kansas City, Kansas, USA, has had two prior call signs since adopting this format in 2001: KWSJ and KKHK. The station is currently owned by Entercom and operations are under a LMA with Reyes Media Group.
KYYS was the longtime call-sign for a rock format station, first located at 102.1 MHz (now KCKC-FM) and, until January 2008, at 99.7 MHz (now KZPT). The calls were transferred to retain presence within the media market, yet has no ties to either of its predecessors. On February 14, 2008, the previous call sign " KKHK" was temporarily assigned to a classical music station in Monterey, California known as "K-Bach" as part of a frequency switch. On February 26, 2008 the frequency swap was complete when the KBOQ call sign was reunited with the "K-Bach" format and the "KKHK" call sign was moved to K-Bach's old frequency which had become a Hank FM station.
