WJBQ debuted on July 15, 1974, as a 3,000 watt Top 40 station at 106.3 FM licensed to Scarborough, Maine, just outside Portland. It was simulcast with 1440 AM in nearby Westbrook, Maine. The main competition for WJBQ-AM-FM was then Top 40 AM Station 1310 AM WLOB, which was one of the highest rated Contemporary Hits stations in the country for a market the size of Portland. In its first Arbitron ratings, WJBQ-AM-FM edged WLOB by about three points. As the audience shifted to FM from AM, it meant a gradual decline for WLOB.
