of the radio industry, most notably improvements to the quadraphonic FM stereo system invented in 1969 by Louis Dorren and improved upon by station chief engineer Brian Brown. The station participated in the National Quadraphonic Radio Committee field trials for the Federal Communications Commission (FCC). WNRZ-FM was actually the first FM station to transmit program audio in quadraphonic sound. Brown also designed and built one of the first combination audio equalizer/compressors, which was used to enhance the poor audio quality of the Collins (now Rockwell Collins) AM radio transmitter at WNRZ. A second device was installed to process the quadraphonic FM program audio. These units gave the effect of the audio to "leap out" of the radio. Community Music Services took over control of WNRZ in December 1974 and four months later, there was a brief stunting period proclaiming "Something BIG is coming to 103 FM." The station's format was returned to as a AR format. This time however without the freeform elements and with an approved station playlist, the new call letters was WIQB. The call letters I-Q-B were chosen because of their resemblance to the station's frequency numbers 1-0-3. The first record played on the new W-103 was "You Can't Always Get What You Want" by the Rolling Stones. WIQB heavily promoted its quadraphonic sound, identifying on-air as WIQB The New QuadRockRadio FM 103 during the 1970's. In 1979, the DJ lineup consisted of Johnny Christian, Randy Z., Jimmy Dulzo, and Chuck Horn, among others. As the 1980s dawned, WIQB, under new owner Ernie Winn, modified its format from a AR format into a Top 40/AOR hybrid A.K.A. Rock 40 format, under their brand new moniker and name Rock 103 WIQB. During the '80's WIQB was usually the highest rated local station in the Ann Arbor market, the jingles touted the fact that WIQB was "Ann Arbor's Number One!" In 1987, the station boosted power to 50,000 watts, dramatically increasing its coverage area to the west (toward Jackson) and north (toward Fenton), although the station's eastward signal remained impeded in the Detroit area by 102.7 FM WKSG (now WDKL). The station went through numerous ownership changes from 1974 onward. During the mid-1990s, WIQB became an AAA station under the ownership of Arbor Radio, LP. In late 1997, Cumulus Broadcasting took control of the station and switched WIQB's format to active rock. WIQB subsequently crashed in the ratings and
