Internet Relay Chat
Many pirate and other radio enthusiasts hang out on the #PirateRadio and #WUNClub IRC (Internet Relay Chat) channels on the StarChat network. This is a place where you can chat with fellow listeners, as well as share monitoring catches in real time.
Joining the chat is fairly easy. You can use the online chat below until you get an IRC client. The Java chat requires a browser with Java enabled.
