## What is JACK 103.1?

Jack FM 103.1 is simply about the music that appeals to adults who are burned out on the repetition of traditional radio formats.  We play great songs that you haven't heard in a while, and have a lot of good-natured fun in between.  Jack FM is home to Missouri's best  local, college, and professional sports.
