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). At night it operates with a mere 3 watts, but still manages to cover much of Clinton County.
In the summer of 2010, WWSJ began to simulcast on translator W262BD 100.3 FM licensed to Dimondale, Michigan, enabling it to get clearer FM coverage of the Lansing area day and night. W262BD operates with 22 watts from a transmitter in the heart of Lansing; despite being licensed to Dimondale, its primary signal contour does not actually reach Dimondale. W262BD is owned by Educational Media Foundation and had previously operated using EMF's Air 1 format; although EMF continues to own the translator, it is being programmed by the owners of WWSJ.
