WCSX is a Detroit-based FM radio station broadcasting a classic rock format. WCSX's transmitter is located in suburban Oakland County in Royal Oak Township near the intersection of 8 Mile Rd. and Wyoming Avenue. WCSX transmits its signal from an antenna 951 feet in height with an effective radiated power of 13,500 watts. 5 other Detroit radio stations transmit their signal from the same tower as WCSX. The station is owned by Greater Media and is licensed to the Detroit suburb of Birmingham. The studios are in Ferndale. Despite its call sign, it is not affiliated with the CSX Corporation.
94.7 FM was originally home to WHFI ("Whiffieland"), featuring a MOR/adult contemporary format with disc jockeys such as Lee Alan (formerly of WXYZ). The original FCC Construction Permit for WHFI was issued to Garvin H. Meadowcroft, President of Meadowcroft Broadcasting, Inc. on January 18, 1957 with an address of 1095 Badder Road in Troy, MI. Meadowcroft began broadcasting on WHFI September 1, 1958 with a power of 20 kW and an office address of 139 Maple in Birmingham. In 1972, WHFI shifted to a syndicated, automated oldies format provided by Draper-Blore called "Olde Golde," featuring hits of the 1950s and 1960s (similar to Drake-Chenault's "Solid Gold" format except without the AC/MOR currents that the Solid Gold format played). The "Olde Golde" format evolved the following year into all-oldies WHNE, "Honey Radio." Sister station WQTE changed its calls to WHND and began shadowcasting the format in 1974; it would continue as "Honey Radio" until 1994, by which time 94.7 FM had gone through several changes. Honey Radio was originally automated using Drake-Chenault's "Classic Gold" format, but transitioned to live personalities (on AM 560 only) around 1980, by which time 94.7 FM had changed format.
By 1987, the adult-contemporary format in Detroit had become quite crowded; in addition to WMJC, Detroit had four other AC stations, WNIC, WOMC, WLTI, and WNTM, with WNIC and the oldies-based WOMC dominating in the format. (The WMJC call letters would be picked for a Top-40/CHR station in Battle Creek, and now are used by a religious station in Kalamazoo. Greater Media would bring the "Magic" format and branding back to the Detroit market with WMGC-FM 105.1 from 2001 to 2011.)
In May 1987, WCSX was launched with Bob Seger's "Old Time Rock and Roll". It was one of the first Classic Rock stations in the United States, and is also one of very few nationwide to have endured with the classic rock format for over twenty-five years.
In August 2005, WCSX launched its digital HD2 sidechannel with a "Deep Trax" format. In January 2014, the "Deep Trax" format was replaced "Detroit's Oldies 94.7 HD2", playing an oldies format. Both WCSX-FM and "Detroit's Oldies 94.7 HD2" stream webcasts for internet listeners.
WCSX's most played bands are classic rock staples The Beatles, Led Zeppelin, Aerosmith, Pink Floyd and hometown classic rockers such as Bob Seger and Ted Nugent. WCSX generally takes a softer, older-sounding approach to classic rock reminiscent of progressive and album-oriented rock radio of the 1970s, since sister station WRIF includes a good deal of harder classic rock titles in its playlist, including 1980s glam metal, which WCSX generally does not play. WCSX competition includes classic rocker WDTW-FM, who returned to the format in November 2011.
WCSX did briefly expand its playlist to harder classic rock in 1996-97 (bands like Rush, Van Halen, Def Leppard, etc.) when the parent company bought then-recently defunct station WLLZ's library, but went back to its toned down approach when WWBR went to a harder classic-rock format.
