Former Toledo talk radio veteran Denny Schaffer won't have to worry about Arbitron ratings for his latest gig. And that, he said, he won't mind a bit. Schaffer was expected to launch a round-the-clock Internet radio network June 15, nearly seven months after a station shakeup at Atlanta's WGST-AM 640, his former full-time employer, left him without a job. Schaffer, in a phone interview from his Atlanta home, said the network, “DennyRadio 24/7,” online at www.dennyradio.com, would include a live program every weekday from 10 a.m. to noon and replays of previous shows between live broadcasts and on weekends.
