Notes/History:
- Late 1990s: Format evolves from rock hits to mainstream rock.
- 1991: Station drops the 'Magic' positioner and returns to the 'Rock 107 WIRX' moniker.
- 1985: WIRX adds live jocks and repositions as 'Magic 107 WIRX'.
- May 1979: Country format is changed to rock-based top-40 as 'Rock 107 WIRX, The Music Works'. The station's name is a take off on its call sign, which when spoken as a word sounds similar to 'Works'. The station's programming remains primarily automated.
- 1969: Format change to country as WIRX. Much of the programming is automated.
- 1965: WSJM-FM signs on so listeners could "discover the new adult world of fine music on WSJM-FM. No announcers shouting at you...featuring the light jazz, show tunes and semi-classical music that has been noticeably missing lately..." (from a newspaper ad, March 29, 1967)
- 1963: Construction permit granted to Mid-West Family Broadcast Group, owners of WSJM AM 1400 for new FM station at 107.1 to be licensed to St. Joseph. Mid-West Family is owned by Bill Walker and Charlie Dickoff.
