Broadcast Your Podcast (BYP) could allow Africans the ability to broacast their messages on a local FM channel. This technology allows podcasters the ability to reach the millions of listeners that don’t have access to the web. The BYP can broadcast up to 100 meters, is made to be rugged and portable, and takes easy-to-find 9 volt batteries.
