What is IRLP?

The Internet Radio Linking Project, also called IRLP, is a closed-source project that links amateur radio stations around the world by using Voice over IP (VoIP). Each gateway consists of a dedicated computer running custom software that is connected to both a radio and the Internet. This arrangement forms what is known as an IRLP Node.
