WWSJ ("Joy 1580 & 100.3") is an AM radio station broadcasting from St. Johns, Michigan on 1580 kHz, featuring a black gospel format.

The station transmits with 1,000 watts during the day using a directional antenna that sends the signal primarily to the north and south (including Lansing, Michigan).

McLravy changed the call letters of WRBJ-AM-FM to WQTK-AM-FM, and implemented a country music format which was simulcast on both stations.

AM 1580 changed calls again in November 1982, this time to WKZY, when the station switched to an MOR format as "Cozy 16".

McLravy sold WKLH-AM-FM, to Lansing Broadcasting Associates in July 1985, and on Labor Day 1985, the format of FM 92.1 was flipped to Album Oriented Rock.

The station featured country music, talk, local news and high school sports.

During a portion of this time it went by News Radio 1580 and featured syndicated talkers Phil Donahue, Church Harder and Jack Ellery.

The station dropped the country music portion of its format in favor of Oldies on Labor Day 1995, and was rebranded as AM-16 The Mint.

Dan Drolett announced the sale of the internet station and its assets to Tony Clark of Rosebush, Michigan in early September 2007.
