The Internet Radio Linking Project (IRLP) revolutionized amateur radio communication by linking repeaters worldwide using the internet. Initially launched in 1997 to connect repeaters across Canada, IRLP overcame early challenges and now operates as a robust global system.

The software operates on a Linux operating system and uses specialized hardware and software to deliver high-quality audio through its links.

The primary goal of IRLP is to provide reliable and cost-effective linking of amateur radio systems without relying on RF links, leased lines, or satellites. IRLP maintains a global network of dedicated servers and nodes, enabling stable worldwide voice communications between hundreds of towns and cities.

IRLP integrates seamlessly with RepeaterBook, providing users with up-to-date information about active nodes. IRLP nodes are identified on RepeaterBook by their unique 4-digit node numbers. On the details page for a repeater hosting an IRLP node, the node's status is fetched in real-time from status.irlp.net.

IRLP uses dedicated servers to relay voice communication over the internet. Each repeater connects to an IRLP node via specialized hardware and software, ensuring consistent audio quality and reliability. Unlike traditional RF-based linking, IRLP minimizes interference and reduces costs.
