WSMC-FM (90.5 MHz) is a non-commercial FM radio station licensed to Collegedale, Tennessee, and serving the Chattanooga metropolitan area.

The call sign stands for Southern Missionary College, SAU's name at the time the station began operations.

The groups complained that it was inappropriate for WSMC to receive federal funding, since it aired more religious programming each week than could be considered a public service.

A few NPR music programs and news briefs remain on WSMC's schedule (purchased separately without a network discount).

The playlist is less diverse than a typical classical public radio station, targeting an older, more conservative listenership.

By contrast, 88.1 WUTC carries mostly news and talk programs furnished by NPR and other public radio suppliers with jazz heard nights and weekends.

On weekends, some national classical shows from NPR and other public radio sources include Performance Today, From the Top, With Heart and Voice, Pipedreams and Sunday Baroque.

Inspirational classical music and Christian radio shows are heard on Friday evenings and nights, as well as in the daytime on Saturdays (the 24-hour period of observance for Seventh-day Adventists).
