The station transmits its signal from an antenna 1,018 feet in height atop a hill located northwest of Marquette and broadcasts with an effective radiated power of 2,600 watts.

WRUP's transmitter was moved in October 2008 to Marquette County from Munising where it had been located since the station first went on the air in 1974.

As WQXO-FM, the station in the early 1970s simulcast the MOR/adult contemporary format of AM sister WGON (later and now WQXO) during the day, and aired beautiful music during non-simulcast dayparts.

The WRUP calls were previously used in Marquette, Michigan in the 1980s on 103.3 FM as "UP 103"; the station is now WFXD.

WRUP is the home and official broadcaster of the Michigan state champion of the Ishpeming Hematites.
