iHeart has launched Black Information Network in Columbus on AM 1230 - Throwback 105.3 is now being fed via WZCB-HD2 instead of AM 1230. (which is interesting because the whole reason iHeart stated on moving 105.3 from PA to Columbus, OH in it's FCC filing was for 105.3 to be an AM revitalization translator for AM 1230 and now it's being fed from an HD-2 channel elsewhere with different content)
