Podcast covering amateur radio
Amateur Logic has been podcasting interesting projects including the active cantenna in episode 3. Their latest episode is straight from the Capital City Hamfest. There is an ARRL review of the amateur radio effort during Katrina, a presentation about Skywarn, and an inspiring amateur satellite radio demonstration. There is not much technical information, but it is a great introduction to what being a ham is about.
