KJZN (105.5 FM, "105.5 The Truth") is a commercial radio station located in San Joaquin, California, broadcasting to the Fresno, California area. KJZN aired a smooth jazz music format until April 28, 2009, and began stunting with Christmas music interspersed with Santa Claus-voiced liners which invited listners to tune in on Friday, May 1 at noon if they "could handle the truth." At noon on May 1, the station flipped to a conservative talk format called 105.5 The Truth, creating a fifth strong-signal conservative talk station in the region (a region which remains without an alternative progressive talk radio broadcaster).
This was the second station in Fresno to use the smooth jazz format, which was previously heard on KEZL (96.7 FM). That station has since been flipped to the Hot Adult Contemporary format (under the call letters KALZ), and is now known as "Alice 96.7".
