IRLP Node 6110

Canberra Region Amateur Radio Club

The Internet Repeater Linking Project aims to reliably and inexpensively link amateur radio systems without the use of RF links, leased lines, or satellites. 

The IRLP uses Voice-Over-IP (VoIP) custom software and hardware. 

IRLP operates a worldwide network of dedicated servers and nodes offering very stable worldwide voice communications between hundreds of towns and cities. All this with unsurpassed uptimes and the full dynamic range of telephone quality audio. 

Excerpt from the IRLP website.

Node 6110 is sponsored by CRARC and is currently operational on the 439.950 Mhz repeater on Isaacs Ridge.

Operational Codes


Node 6110 responds to the standard IRLP DTMF code set. To connect the node to another node you simply key up and transmit the destination node number via DTMF. A list of destinations may be found on the IRLP Website and also on the G4EID-KM8H Status Pages.

The node may also be connected to a reflector. A reflector allows multiple nodes to connect to it simultaneously and retransmits what it receives from any one node to all others connected. All reflector node numbers start with a ‘9’ with the last digit of the number being a channel on that reflector. For example node 9509 refers to reflector 9500 channel 9. There are ten channels on each reflector, numbered 0 to 9 and nodes connected to different channels do not hear each other. To hear another node connected to the reflector you must be connected to the same channel.


Node 6110 also supports the EchoLink network as ‘VK1RBM-R’ (Node 150524).

To connect to an EchoLink station via the node you send via DTMF the station number prefixed with a ‘*’ (star). For example, to connect to the *AUSSIE* EchoLink conference server you would send, via DTMF, *95092.

A list of EchoLink stations and conferences can be obtained from your favourite EchoLink client, or from the G4EID-KM8H Status Pages.


To disconnect an IRLP or EchoLink connection simply send 73 via DTMF.

Feature Codes

The node supports a number of features other than just linking two repeaters. 

Active Features

Active features are activated by sending a ‘#’ then the feature number via DTMF. Currently the following features are supported;

#0 (or 0000)Node Id
#1Node Status
#2Local Time
#3UTC Time
#4Last Node Connected
#50The current temperature at the Canberra Airport (via BOM Website)
#51The current weather at the Canberra Airport (via the BOM Website)
#60The current temperature at the Tuggeranong AWS (via the BOM Website)
#61The current weather at the Tuggeranong AWS (via the BOM Website)
#***Connect to a random IRLP node
#6**Connect to a random VK/ZL node

Passive Features

Passive features happen automatically or in the background, ie without you actively triggering them.

The following passive features are enabled;

  • APRS node broadcast – The status and location of the IRLP node is broadcast every hour and at the beginning and end of every connection via an APRS object labelled “IRLP-6110”. The object icon is a circle containing the status of the node, I for idle, C for connected, B for busy. By looking at your APRS display you can instantly see the status of the node and if it is connected, by looking at the object information you can see who it is connected to.
