 Cumulus purchased WIXO and its sister stations from Townsquare Media.Originally on 99.9 MHz before 2006, it moved to 105.7, a much higher-power license that reaches a large portion of Central Illinois.The name is based on several factors, one being the frequency (105.7) and the other being the fact that it recently relocated from 99.9 having been under the name 99X, and the "X" in the name had become an inherent part of the station.
