WPNN

The original call sign was WPFA, standing for Pensacola, Florida. Owner J. William O'Connor received a construction permit from the Federal Communications Commission (FCC) in 1955 for a new station at 790 kilocycles. O'Connor also had a construction permit to construct television station WPFA-TV.

WPFA signed on the air in October 1956. It was a daytimer, powered at 1,000 watts but required to go off the air at sunset. WPFA was a rare radio station in that era to have a female program director, Barbara Holt. O'Connor sold the station in 1958 to Edwin H. Estes but remained as the general manager.

For most of the 1960s, 70s and 80s, WPNN had a country music format. In 1990, the station switched its call letters to WSWL. As music listening moved to the FM dial, WSWL tried an all news radio format, largely provided by CNN Headline News, though it also would simulcast newscasts from WEAR-TV on weeknights. In 2002, it changed its call sign to WPNN and later switched to an all-talk format.

In February 2016 the station acquired a move-in FM translator from Carrabelle, Florida, as part of the AM Revitalization project approved by the FCC. It began transmitting on 103.7 MHz (W279CY) in early April 2016. (Taken from Alabama Broadcast Media Page)
