WGBJ (102.3 FM) is a commercial radio station licensed to Auburn, Indiana, and serving the Fort Wayne metropolitan area.

The transmitter is on Quincy Street in Altona, Indiana, about 30 miles north of Fort Wayne.

Following a sale from Summit City Radio Group to Three Amigos Broadcasting, WXTW adopted a Spanish-language regional Mexican format as "Mega 102.3" at midnight on September 1, 2006.

On September 21, 2009, the station adopted the slogan "Power 102.3" and flipped from regional Mexican to a contemporary hit radio format.

On January 9, 2019, Sarkes Tarzian, Inc. acquired WGBJ—which by then had returned to regional Mexican as "La Unica 102.3"—for $515,000 and flipped it to a simulcast of WAJI-HD2 which was carrying an alternative rock format.
