The station signed on 1050 kHz in 1979 as WCGA. The format was a locally produced and formatted CHR. It became automated as WTPO in 1986. The format then became gospel as WPBE ("Praise 1050") in 1989. In September 2003, the station changed operating frequency from its original 1050 kHz to its current dial position on 1040 kHz. In May 2005, the station changed its programming format from gospel music to the "Planeta X" Spanishtalk radio format (which moved from 1310 WPBC).
In early 2008, it changed formats to "Spice Radio Atlanta" broadcasting with Desi/Hindi music and talk.
By mid-2009, the station was simulcasting with 1080 WFTD's "Atlanta Radio Korea" programming. The Korean programming of "Atlanta Radio Korea" was then heard exclusively on WPBS and dropped from WFTD, which then started carrying Spanish-language programming.
When Atlanta Radio Korea, owners of WPBS, purchased WQXI from Entercom and flipped it to from its simulcast of WSTR on December 15, Vietsong Media, owners of WFTD, purchased WPBS and has flipped the format to Vietnamese radio, as of January 1, 2017.
