I don’t listen to a lot of live radio anymore. Instead, I tend to listen to a lot of podcasts. I can find content specific to my area and take it with me on the go. Here is a great list of podcasts for Educators (all for free and in no particular order):
Edutopia Webinars - Edutopia presents engaging webinars hosted exclusively for our audience of educators, parents, and administrators throughout the year. These interactive events are free and universally accessible thanks to support from foundations, advertisers, and donors. Each webinar is designed to connect our valued audience with thought leaders in the movement for educational reform, providing opportunities to learn about the latest research, tools, and ideas from experts in the field. Note: Most Edutopia Webinars are large files, approximately an hour long.
Education & Teaching from Yale - Yale Professors and special guests speak on teaching, education and the important role education plays in our lives.
Great Teachers by Harvard University - Harvard’s Great Teachers invites you to discover our faculty sharing their ideas, very much as they do every day with undergraduates at Harvard College.
Center for Teaching and Learning at Stanford University - The Stanford Center for Teaching and Learning supports the effective communication of knowledge and the love of learning by faculty inside and outside the classroom, by graduate students in their roles as apprentice scholar/teachers, and by undergraduates as they take their place in the community of scholars.
Google Tools - Google is much more than a search engine. It is a suite of free software and services that can enhance learning, engage students, and make the work of teachers easier. This series of podcasts demonstrates the usefulness and applications for some of Google’s most innovative products including custom search engines, Google earth, iGoogle, Google Calendar and Google Docs. Each podcast will consist of a screencast demonstrating the product in action and suggesting applications for use in the classroom.
Department of Education Public Seminars at Oxford University - Public seminars from the Department of Education. Oxford has been making a major contribution to the field of education for over 100 years and today this Department has a world class reputation for research, for teacher education and for its Masters and doctoral programmes. Our aim is to provide an intellectually rich but supportive environment in which to study, to research and to teach and, through our work, to contribute to the improvement of all phases of public education, both in the UK and internationally.
Technology Integration by Edutopia - Integrating technology into classroom instruction means more than teaching basic computer skills and software programs in a separate computer class. Effective tech integration must happen across the curriculum in ways that research shows deepen and enhance the learning process. In particular, it must support four key components of learning: active engagement, participation in groups, frequent interaction and feedback, and connection to real-world experts. Effective technology integration is achieved when the use of technology is routine and transparent and when technology supports curricular goals.
Harvard EdCast - The Harvard EdCast is a weekly series that features a 15-20 minute conversation with thought leaders in the field of education from across the country and around the world. Hosted by Matt Weber, the Harvard EdCast will 
serve as a space for educational discourse and openness, focusing on the myriad issues and current events related to the field.
NPR Education - From NPR: perspectives on great teachers, the science of learning, classroom dynamics and more. The best of Morning Edition, All Things Considered and other award-winning NPR programs.
