A journalist who came to Miami via Venezuela and New York with more than 30 years of experience, Julio Cesar Camacho never gets lost in the maze of this city's Spanish-language radioverse, prone to sensationalist noise and cheap jabs. Every day from 5 to 7 p.m. on Actualidad (WURN-AM, 1020), Camacho is just as likely to level hard-hitting questions at politicians across the ideological spectrum as to interview doctors working on important research, musicians performing across the globe, or local professors conducting sociological studies. He welcomes anyone and everyone to his show, maintains a cool and collected stance, and delves deep into far-ranging issues. And perhaps most important, he seems comfortable enough to understand the story isn't about him.
