I've had a lot of complaints about the fact that it's hard to listen to radio live on PFA, due to the players being antiquated.
Among the complaints:
1) The main player requires Flash, which most people don't have anymore, and which is completely ending support in January 2021
2) You need to click a separate link to listen on a mobile device
3) Those links stopped working anyway
Please try to go to the Radio tab now, and see if you can listen to the streaming reruns of the show. Make sure to press the "play" button.
Let me know if it doesn't work for you. No Flash required anymore.
