The station signed on the air in 1951. It was a 500-watt daytimer. On November 19, 1965, it added a sister station,
WKKB-FM at 92.1 MHz. In the 1960s and 70s, the two stations simulcast a popular
Top 40 format. Today, the FM station is a
country outlet as WLTU. The stations were purchased by Seehafer Broadcasting in 2018, the owners of its longtime rivals,
WOMT (1240) and
WQTC-FM (102.3), and merged into Seehafter's facility soon after. In early May 2020, WCUB started
simulcasting on
FM translator W246DY at 97.1 MHz, as a part of the
FCC's AM revitalization plan. ==Programming==
