In this latest installment of our Lost and Found Sound series, NPR's Don Gonyea remembers the heyday of powerhouse AM radio. Gonyea grew up in Detroit, where the big station in the 60's and 70's was CKLW. It broadcast from across the Detroit River in Windsor, Ontario. It was a loud, glitzy noise-making enterprise. Everything was shouted — even the news. The 50,000-watt giant spewed rock and roll and hyped-news across 28 states and mid-Canada. Gonyea describes the formula that made CKLW and its imitators successful.
