As FM radio was still burgeoning and not very popular, it served as a simulcast outlet of its AM sister. This arrangement continued until the stations were sold in 1971 to the Jonel Construction Company (dba Cover Broadcasting). Shortly afterwards, the call letters for the AM station and the TV station were changed to WJNL, and the new owners were granted a construction permit to move WARD-FM to 96.5, which allowed a power increase to 50,000 watts. For this to happen, WARD-FM at 92.1 had to be closed with a dark license until a new owner could be found, as licensees at that time were forbidden to own more than a single AM and a single FM in one market. WJNL-FM 96.5 then signed on the air in 1973, and 92.1 went silent in 1972. The license for 92.1 was acquired in 1973 by Community Broadcasters, which signed the station back on in September of the following year under the call letters WAAT, and under a religion-based format. The station's facilities moved from Franklin Street to Locust Street in Johnstown. Ronald Smith served as the company's president. This incarnation of the station lasted less than two years. WAAT was sold August 23, 1976 to William C. Bland, owner of the Bland Group, which also owned WNCC in Barnesboro, about a half hour north of Johnstown. The call letters were switched to WFMM and the studios moved to 634 Main Street, and an easy listening format was adopted. Ownership would change again by the end of the decade. WFMM was sold again on August 29, 1980 to Conemaugh Communications Corporation, a local company headed by Fred Glosser, whose family owned the Gee Bee discount department store chain. The studios were moved to 516 Main Street, and the call letters were switched to WGLU, with the format moving from easy listening to album rock. The station began to call itself "Glu 92", increased its power and embarked on a heavy advertising campaign. Towards the mid-’80s, WGLU started including more Top 40 tracks in its music rotation. In August 1987, WGLU was sold to PAC Media, a company headed by Warren S. Diggins. One month later, the rock format was abandoned. Targeting younger listeners, WGLU became "Power 92", keeping the same call letters for the newly created Top 40 format. On July 31, 2000, WGLU and sister station WQWK licensed out of Ebensburg, Pennsylvania swapped frequencies.
