I strongly recommend that you tune in to Catholics Answers Live on Mondays-Fridays from 6-8pm ET (4-6pm CST). You can listen live during those hours or listen to the free podcasts. Click here for the link.
Another live radio show (and free podcast) I heartily recommend is Right Here Right Now With Patrick Madrid. This show plays live on Mondays-Fridays from 4-5 pm ET (2-3pm CST). Click here for the link.
