WSNX-FM (104.5 MHz "104-5 SNX") is a top 40 (CHR) radio station located in iHeartMedia's Grand Rapids, Michigan headquarters.

Goodrich Radio Marketing purchased the frequency in 1984, and quickly changed the beautiful music format to Top 40 and used the moniker "Sunny-FM" on-air.

WSNX moved to Grand Rapids (at 2610 28th Street) in 1996, where it was occupying the same offices of sister stations WODJ and WKWM.

In early 1997, Clear Channel purchased WAKX from Federated Media and flipped it to "Continuous Hit Music I-96" as WVTI.

The station identified itself as "Grand Rapids' Hottest Music, 104.5 WSNX" or just SNX in jingle form.

WSNX moved again to downtown Grand Rapids after it was purchased by Clear Channel Radio in September 1999, and took the "Continuous Hit Music" moniker and a slightly more mainstream, though still rhythmic-leaning, CHR format, as WAKX was retooled as a Hot AC to compete with WLHT.
