sentences:  The KWWV call letters originally were used on the 99.7 FM frequency, which carried a smooth jazz format called "K-Wave".In 1997, smooth jazz was dropped in favor of rhythmic contemporary hit radio (CHR) as "Kiss 99.7".In the fall of 1999, station owner American General Media moved the format and the KWWV call sign to 106.1 FM to provide better signal coverage throughout San Luis Obispo County.
