Southern Radio Shows

Hi All, this might seem a little off topic but I'm wondering if you could help me.

I’m currently working on a documentary project and am looking for recommendations for a male presented US radio show. Preferably the character will host a local talk show - would prefer to stay clear of the bigger commercial stations. He has to be a good listener and a gentle type of interviewer. Just thought some of you guys may have some suggestions to offer or favoured shows to listen to? As I'm based in Dublin, Ireland I'm having to research online and ask for help!

Any advice would be appreciated. Many Thanks, Shane
