WLRN-TV, virtual channel 17 (UHF digital channel 20), is a PBS member television station located in Miami, Florida, United States. The station is owned by the Miami-Dade County Public Schools district, alongside NPR member radio station WLRN-FM (91.3). WLRN maintains studio facilities located on Northeast 15th Street and Northeast 1st Avenue in Miami, and its transmitter is located at McTyre Park in Miami Gardens. WLRN operates twenty closed-circuit educational channels for use by public schools within Miami-Dade County.
Prior to the station's sign-on, the UHF channel 17 allocation in the Miami-Fort Lauderdale market was occupied by ABC affiliate WITV (channel 17), which ceased operations shortly after losing the ABC affiliation once WPST-TV (channel 10, now WPLG) signed on in August 1957. WLRN-TV first signed on the air on September 7, 1962 as WSEC-TV; it was the second non-commercial educational television station in the market. Operating an a member station of National Educational Television (NET), WSEC was originally owned by the Dade County School Board.
The Dade County School Board had previously owned a portion of the VHF channel 2 allocation in the market (which was licensed for educational use), as part of a shared-time agreement with Community Television Foundation of South Florida, owners of WPBT. Under the arrangement, the School Board operated the channel 2 frequency for five hours each day as WTHS-TV, carrying instructional television during the daytime hours, while the Community Television Foundation would take over the channel for two hours each evening to broadcast WPBT. This arrangement continued even as the 1970 formation of the Public Broadcasting Service (PBS) brought an increase in WPBT's broadcasting hours. Eventually, the School Board and the Community Television Foundation decided to end the split-station arrangement, with the Dade County School Board turning over the WTHS license to the Federal Communications Commission (FCC) in 1978, while WPBT took over channel 2 full-time. WSEC-TV's call letters were changed to WLRN-TV in 1979, to match its sister public radio station.
The station's digital channel is multiplexed:
|Channel||Video||Aspect||PSIP Short Name||Programming|
|17.1||1080i||16:9||WLRN-HD||Main WLRN-TV programing / PBS HD|
WLRN Learn, broadcasting on digital subchannel 17.2, features educational, lifestyle and best-of programming, along with selected programs from MHz Worldview.
WLRN-TV terminated its analog signal, on UHF channel 17, on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal remained on its pre-transition UHF channel 20. Through the use of PSIP, digital television receivers display WLRN-TV's virtual channel as 17.
