Longtime “Mix 107.3” WRQX Washington D.C. morning host Jack Diamond is taking his talents to South Beach. Diamond, who departed Cumulus’ WRQX in April and was subsequently replaced by the syndicated Bert Show, will join Lincoln Financial Media AC “101.5 Lite-FM” WLYF for mornings. Diamond will be joined by former “97.3 The Coast” WFLC morning host Julie Guy. Incumbent morning host Ellen Jaffe will shift to afternoons. Before exiting in April, Diamond had been with WRQX for 24 years.
