Licensed to Bay City, Michigan, it first began broadcasting in 1925 as WSKC at 1150 kHz, with its call sign reflecting its ownership by the World's Star Knitting Co.

WBCM-FM was located at 96.1 mHz and broadcast from an over 300 foot (90m) Blaw-Knox tower at the station's Bay City east side studio on Tuscola Rd, initially signing on in 1947.

Purchased by Liggett Communications earlier in 1973, on August 27, 1973 the FM calls were changed to WHNN and the station adopted a Top 40 format as "Super Win".

Later, Liggett built a new FM tower location in Quanicassee to alleviate a short spaced situation with WHTC-FM Holland, and the power was upped to a legal maximum of 100,000 watts.

In February 1978, Liggett changed the AM format to country, and the call letters to WRDD (Big Red Radio),[2] and also built a new 5 KW AM directional transmitter site for the station along M-84 in southern Frankenlust Township, Michigan.
