KBBL radio is a local radio station in Springfield. It broadcasts on 102.5 FM. It serves the area with a male-targeted AC format. The radio station was owned once by Mr. Burns as well as others. Per FCC regulations, the prefix of K represents broadcasting facilities west of the Mississippi, meaning that Springfield must be located somewhere west of that river. However, if the station started broadcasting with the abbreviation before 1912 (when the FCC regulation went into effect), it legally could have been grandfathered in. Regardless, the station is still one of the strongest, yet sadly one of the least specific, definite clues as to Springfield's location in the United States.
