I just discovered a resource that you may know about, but thought it worth mentioning. This is not an endorsement-- if you know of other services like this, let me know.
www.ontheradio.net provides contact info for all radio stations.
I did a quick search for stations with a talk/news format within 40 miles of my zip code. Instantly, I got a list of 7 stations with their websites.
I figure that most stations with this format spin for Republicans, but it might be worthwhile to call in or email with other points of view. On a story like the one about Allen's racially charged comments to Sidarth in Break, VA, they need to hear the other side.
