			== Using IRLP with a radio ==

			'''Step by step process'''

			* Look either [http://status.irlp.net/ here] or [http://irlp.g4eid.co.uk/status/ here] to find out which node numbers are available and where they are located. Both these lists are updated regularly, and give information about which nodes are connected to each other. If you use [http://earth.google.com/ Google Earth], this [http://www.irlp.net/setup-irlp.kml kmz file] will show you the connections between IRLP nodes.

			* Locate a node close to you and one that you would like to contact. Repeater listings such as [http://ham.longlandclan.yi.org/ this one] for Australia, will provide useful information in your search.

			* Use a DTMF microphone and dial in the node number that you wish to contact. A message will tell you if you either are successful or unsuccessful.

			* There will be a delay between sending and receiving when using IRLP or [[Echolink]]. Best protocol is to wait a couple of seconds between hearing the other person and starting to talk yourself.

			* When you have finished talking, use the DTMF buttons and dial in 73. This will disconnect the nodes.

There are a number of radios that are suitable for this purpose. Information on some of these and how to connect them to the node computer can be found on [http://www.irlp.net the IRLP website.]

			Most nodes operate in either the 2m or 70cm bands. IRLP can be run either in simplex or with split frequencies. Club owned nodes are usually attached to a repeater, whereas privately owned nodes usually are not, so run as simplex operations.

			== How does it work ==

			IRLP uses a Voice-Over-IP (VoIP) software called [http://speak-freely.sourceforge.net/userguide/ar01s03.html Speak Freely]. Speak Freely runs on
			[http://www.linux.org/Linux].

			The operator connects to an IRLP node with a standard FM transceiver. Voice from the node radio is sampled using the A/D converter at the input of the node computer soundcard. The digital stream created is at 120kbs.

			The data stream is compressed by a factor of 4 to 32kbs. This data is then broken into packets which are transmitted along a DSL connection to a remote node (using VOIP). The packets are re-joined to a data stram at 32kbs, and then decompressed back to 120kbs.

			Finally the data stream is converted back to audio and transmitted by the remote node radio. A user at the remote end receives the audio into a standard FM transceiver.

			A more detailed description is available at the [http://www.irlp.net IRLP site.]

The key philosophy behind the project was and remains for it to provide these links so that amateurs with inexpensive transceivers, or licence classes with low power limits, had access to a worldwide network.
