On the blog for my Get Wisdom podcast, I've uploaded a brief article - also linking to a short series I wrote a few months ago - about creating podcasts. You might find this helpful if you're thinking about creating an Orthodox podcast.
re/CALL is a podcast by Jason Barker for Orthodox Christian teens. Each episode of re/CALL looks at how your relationship with God and His Church can help you in every aspect of your life: dealing with family, friends, school, work, your spiritual life, and everything in-between! The program is a production of the Antiochian Orthodox Department of Youth Ministry and Ancient Faith Radio.
