KFXN HD2
By February 2005, the station was one of a handful of stations in Minnesota to use iBiquity's HD Radio system for digital radio broadcasts. On April 25, 2006, Clear Channel announced that KTLK's HD2 subchannel will carry a format focusing on classic country hits from their Format Lab. In August 2009, the format was changed to classic rock.
On August 22, 2010, the HD2 channel began instead carrying the audio of KFAN (1130), mainly in order to allow KFAN's signal to be relayed to K279AZ, an analog translator station at 103.7 FM atop the IDS Center; HD Radio subchannels are allowed to be carried via translator stations.
