KZSN (102.1 FM, "102.1 The Bull") is a radio station broadcasting a country music format.

In 1983-84, KSKU upgraded its signal for better coverage over Wichita to compete against then Top 40 stations KEYN (Now Oldies) and KKRD (now Alternative Rock KTHR) in three-way Top-40 battle.

In early 1986, the station's studios were moved to Wichita, and on February 14, 1986, at 3 p.m., the station's call letters were changed to KZSN and flipped to a country music format as "Kissin' 102" to compete with longtime Wichita ratings leader KFDI AM/FM.

[5][6] The final two songs on "Kissin' Country" were "How Country Feels" by Randy Houser and "These Days" by Rascal Flatts, while the first three songs on "The Bull" were "Anywhere with You" by Jake Owen, "Even If It Breaks Your Heart" by Eli Young Band and "Pirate Flag" by Kenny Chesney.

The station is home to "The Bobby Bones Show" from 5-10am, Jim Dorman 10-3, and Michelle Buckles from 3-7pm.
