Just to be clear, this is NOT all my own work. I have modified the radio example that came with the pifacecad library. It was modifed to use pulse audio for output, with different stations. I have also added a suspend function instead of being able to kill the python process, and a lcd ticker to display longer messages, among other small changes. I've posted it here incase someone finds it useful.
