In 1971, WRNW changed to an easy listening format, and then to Top 40. In 1972, the station transitioned to a progressive rock format. On Monday, July 9, 1973, WRNW inaugurated transmissions from its new Briarcliff Manor studio on the second floor of a small house at 55 Woodside Avenue. The new transmitter was in Irvington, blanketing White Plains, Yonkers and lower Westchester. It was there, in 1976 that Howard Stern obtained his first paying radio job as a DJ and program director. Meg Griffin, later of WNEW-FM, WPIX, WXRK, WFUV, and Sirius Satellite Radio, was also music director of the station during the mid-70s. Ted Utz also began his professional career at the station in 1976 and went on to program and manage pioneering stations like WMMR in Philadelphia and WNEW FM. Earle Bailey (WLIR, WNEW-FM, WMMR Philadelphia, Sirius XM Radio's "Deep Tracks") manned a shift at the station during the progressive rock era as did Doug Berman, now producer of National Public Radio programs "Car Talk" and "Wait Wait... Don't Tell Me!".
