A few years ago, Citadel(when they owned 105.9) attempted to go nearly H2H with Regent alternative KFTE when they branded 105.9 "Extreme Rock".
KFTE is fairly close to active rock for employing an "alternative" format designation.
Interesting that KRDJ would steer more toward active rock, but not that surprising. Their attempt at CR made me want to listen to ZMZ more. There were times when RDJ's flow was whacked. So now, when a listener gets tired of Planet they have another button in 93.7. They may have a better time on the street selling this format versus trying to go against Eagle 98.1...
