WLRN-FM is a class C1 FM station on 91.3 and is the main public radio station for South Florida and the Keys based in Miami. The station is owned by the Miami-Dade County Public Schools and is the area's NPR member station.
WLRN first signed on in 1948 as WTHS-FM, on 91.7 MHz. The station later moved to 91.3, changing the calls to WLRN-FM. It was a charter member of NPR in 1970, and is the longest running NPR member in Florida.
Its HD2 service was WLRN Xtra HD, "South Florida’s Alternative News and Talk Station", featuring talk programming by day and BBC World Service at night. Until December 2, 2007, HD2 carried " Classical 24", which offered classical music 24 hours per day. Classical 24 has since moved to another public radio station, WKCP 89.7 FM, after that station's acquisition by Classical 24's parent, American Public Media. But 89.7 was sold to K-LOVE On July 17. Classical music has returned to WLRN's HD-2 as of August 10, 2015. Employees are part of AFSCME union local 1187 contract .
The station also maintains its long-time radio reading service for the blind on an analog subcarrier.
The school board also owns WLRN-TV, the secondary PBS member for South Florida.
