[2] With its effective radiated power (ERP) of 100,000 watts[3] and 317 meters (1,040 ft) in height above average terrain (HAAT), KNXR can be heard through much of southern Minnesota, western Wisconsin and northern Iowa.

KNXR played quarter hour sweeps of mostly instrumental cover versions of popular songs, as well as Broadway and Hollywood show tunes.

On February 24, 2015, after a couple of hours of stunting with the local audio feed from NOAA Weather Radio, KNXR flipped to a Hot Adult Contemporary format, branded as "97.5 Pulse FM".

On March 4, 97.5 began stunting with a loop of "Tie Me Kangaroo Down, Sport" by Rolf Harris, along with recorded announcements that a "new radio station is coming to Rochester."
