Cumulus Media has announced that Modern Rock stalwart “99X” will return to the Atlanta airwaves on Friday, April 17 at 9:09am via the 97.9 translator that Cumulus recently acquired. W250BC Riverdale, GA will duplicate the 99X programming that has continued to air on 99.7-HD2 since WNNX gave way to CHR Q100 in January 2008. The 250 watt translator covers much of Atlanta proper.
