Ok y'all made me fess up. I'm a radio geek and here's a page that allows you to control online radios in a variety of locations across the country (world actually.) There's no blackouts and no blockages other than the vagaries of AM radio reception.
Find the closest radio to Mpls, click on it, and set the frequency 830 khz (MW or medium wave is AM) You can pick up other feeds as well, KMOX and 670 in Chicago will give you Cardinal and Sox games.
It's techy but it works. You're welcome.
