BhamRadio.com WPSB Returns to Historic WENN Calls; Adds Urban Talk Programming WPSB-AM 1320 "Radio Centro" has ended its LMA with KPI Latino and returned to its previous call letters of WENN, ones the station last used more than 26 years ago. The WENN calls were last seen on AM 1320 in January, 1983, when the station became gospel WAGG. Since that time, the WENN calls have continued to be part of the Birmingham radio landscape, most recently at the current WVVB (105.5 FM). AM 1320's regional mexican format, "Radio Centro", previously heard on the station since January, 2007, ended on March 24. The following day, WENN began a simulcast of co-owned urban adult contemporary WBHK "98.7, Kiss-FM". In late April, WENN began offering blocks of talk programming (urban talk) during the day.
