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 is 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.

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.


Since the mid-1990s, the station has had five broadcast translator stations, evenly-spaced down the Florida Keys. Listed from northeast to southwest, they are:

These stations do not yet appear to carry HD Radio.

In late September 2008, WLRN launched a full-powered, class C3, 12 kW station, WKWM 91.5, in Marathon, Florida, which simulcasts WLRN programming for the southern Keys.


In June 2011, WLRN dropped ties with the Florida Public Radio Network, a statewide network of public radio stations designed to provide coverage of the Florida Legislature and other Florida-relevant issues, partly in response to its producer, WFSU-FM in Tallahassee, receiving $2.8 million in funding for various services related to Florida government, including $497,522 for "statewide government and cultural affairs programming", which includes the Florida Public Radio Network. This is despite the $4.8 million of funding to other public radio and television stations (including WLRN radio and television) vetoed by Governor Rick Scott in May 2011. In its place, WLRN will join the joint partnership between the St. Petersburg Times and The Miami Herald in coverage of state issues from the papers' Tallahassee bureau.[1]
