WTHS-FM maintained a long-time radio reading service for the blind on an analog subcarrier.
[10] In the late 1970s, WLRN-FM was given permission by the Federal Communications Commission to boost its power to 92,000 watts on its 400 foot tower.
But 89.7 was sold to the Educational Media Foundation (EMF) for its "K-LOVE" Christian Contemporary music network on July 17, 2015.
On October 16, 2015, WLRN-FM announced it would lease the HD2 subchannel of WFLV in West Palm Beach and its FM translator 101.9 W270AD from the Educational Media Foundation (EMF).
Until then, listeners in the Palm Beach area had to try pulling in 91.3 WLRN-FM from its main transmitter in Pembroke Pines, quite distant for an FM signal to reach.
In 1982, a new NPR station signed on in Fort Pierce, WQCS 88.9 FM, owned by Indian River State College.
In June 2011, WLRN dropped ties with the Florida Public Radio Network.
That is a statewide network of public radio stations designed to provide coverage of the Florida Legislature and other Florida-relevant issues.
This was 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.
In its place, WLRN-FM signed on to a joint partnership between the Tampa Bay Times and The Miami Herald in coverage of state issues from the papers' Tallahassee bureau.
