 In 1980, the FM band was still new territory for Top-40 radio.Boston's Kiss 108 had only started one year prior and was very popular, routinely beating Top 40 AM station WRKO in the ratings.Cape Cod needed its own similar station to compete in its own market, and in May 1980, 104.7 changed its call letters to WKZE-FM and began its own programming, branding itself ""KZ 104 FM"".
