About B103.9

Southwest Florida's hit music station on 103.9 FM

B103.9 is a contemporary hit radio station on 103.9 FM serving the Fort Myers and Naples area. Its FCC licence is for WXKB, licensed to Cape Coral, Florida, and held by Sun Broadcasting, Inc. Sun bought it from Beasley Media Group in 2026.

The station signed on in 1975 as WRCC with a classical format and has since grown from 3,000 to 100,000 watts. Afternoons carry the syndicated On Air with Ryan Seacrest. WXKB's HD2 digital channel feeds FM translators on 96.5, 101.5 and 105.1. The station's website promotes upcoming Southwest Florida concerts and comedy shows, and its contest line is 239-948-1039.

RADIO JOX plays the station's StreamTheWorld (Triton Digital) stream, the same service behind its official web player. The site's player configuration names the Triton station WXKBFM. RADIO JOX built the address from StreamTheWorld's public stream pattern, and the stream identifies itself as WXKBFM.
