WLRN-FM is a class C1 FM station on 91.3 MHz, 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 flagship NPR member station, therefore carries Morning Edition, All Things Considered, Weekend Edition, and Wait Wait...Don't Tell Me!. It is also affiliated with Public Radio International and carries The Takeaway and The World, among others. It airs its own locally-produced music programs Evenin' Jazz with Tracy Fields on weeknights, and Night Train on Sundays, before being taken over by the BBC World Service during the overnights.
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.[1] 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 HD2 as of August 10, 2015 under the Classical 24 service once again but is now referred to as WLRN Classical HD2. 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 on Channel 17.
