It'd be a shame for them to move away from 620 AM, since their transmitter is so powerful. I'm not sure what reach WISN has, but I've always enjoyed being able to listen to 620 AM from most places in the state. I know there are issues with the statewide network, but truthfully, how many places in the state that are without an affiliate are able to get WTMJ? Otherwise, you can get the game through a local station and wouldn't need to rely on 620. As the article mentions, the power of the station is less important now a days than some of the other factors.
