IRLP (internet radio linking project) Is a system of linking radio stations and repeater stations anywhere in the world via the internet, using VOIP technology. This system was invented and developed by Canadian David Cameron. Initially (1997) using Windows and Vocaltecs i phone Voice over IP audio transceiver. This proved to be unstable and difficult to control and was replaced with a Linux platform using Speak Freely software. Originally running Red Hat 7.3 or 9 and later Fedora, then CentOS.
Participating stations (nodes) originally had a 3 digit number, later changed to a 4 digit number. These numbers entered via the DTMF keypad of the user (any station within range of a node) will connect the user to their chosen node, providing that node is activly connected to the system.
It is also possible to connect multiple nodes together (a little like a chat room) by connecting to a 'Reflector' enabling many nodes anywhere in the world to communicate simultaneously.

Construction of an IRLP node requires a PC (minimum 200Mhz clock pentium or AMD), an IRLP board and a transciever. The IRLP board will require access to the squelch and PTT (controller in the case of a repeater). The audio is connected to your PC sound card.

The network is designed so that the user is still required to use a radio (transciever) to operate through the node. Unlike echolink, where a user can join and use the network from a PC .
