WUPK

WUPK (94.1 FM) and WIMK (93.1 FM) are a pair of radio stations based in the Upper Peninsula of Michigan (licensed to Marquette and Iron Mountain, respectively). The stations broadcast an active rock format branded as 93 Rock and 94 Rock (not simulcast), and are currently owned by Sovereign Communications.

WIMK is the older of the two stations, beginning life as a beautiful music station before switching to country music by the early 1980s. In 1985, the station adopted a Top 40 (CHR) format as "K93," and then evolved to an album-oriented rock format later in the decade, originally branded as "K-Rock." WUPK signed on as a simulcast in the 1990s, and by the 2000s, the stations adopted the name "Classic Rock: The Bear", joining Northern Star's existing group of Northern Michigan stations with this branding, though their programming was not part of that specific network of stations, and aired its own music rotation.

Following the stations' sale from Northern Star Broadcasting to Sovereign Communications in 2010, WUPK & WIMK broke their simulcast and re-imaged as "93 Rock" and "94 Rock" accordingly, adopting similar identities, logos, and playlists as Rock 101, Sovereign's existing active rock station in Sault Ste. Marie, Michigan at WSUE 101.3 FM. WUPK/WIMK DJ Nikki "At Night" Peterson currently provides pre-recorded station bumpers for WSUE's nighttime music rotation.
