History
WSOY first received a construction permit for a new FM station on October 7, 1946. The original frequency was 98.7 MHz, and later as 102.1 MHz. It received its full license on February 2, 1949, powered at 31,200 watts, broadcasting on 102.1 MHz.[2] The switch to 102.9 MHz received a construction permit in August 1959 and license on May 31, 1960. The increase to the current 54,000 watts received its construction permit in May 1961 and license on September 7, 1961.[2]
At first, WSOY-FM largely simulcast the programming of WSOY (1340 AM). By the late 1960s, it tried an automatedcountry music format, separate from the AM station. It later switched to beautiful music, playing quarter hour sweeps of mostly soft instrumental cover versions of popular songs.[8]
In the early 1980s, WSOY-FM adopted a Top 40 format and the name "Y-103" to distinguish itself from its AM partner, though it remained mostly on automation until 2000.[8] At that point, disc jockeys were hired.
On February 1, 2024, Neuhoff Media sold radio stations in Danville and Decatur IL to Champaign Multimedia Group for $2 million and has since closed in May 2024.[9]
