 WSFP-FM changed its calls to WGCU-FM on June 13, 1997, two months before FGCU opened.Despite operating at a full 100,000 watts, the main WGCU-FM signal is barely listenable in parts of Collier County.This is because its transmitter is located in southern Charlotte County; however, its grade B signal reaches much of northern Collier County, including much of Naples itself.
