What Is AllStar?

AllStarLink is a network of Amateur Radio repeaters, remote base stations and home nodes accessible to each other via Voice over Internet Protocol (VoIP). AllStarLink can run on a dedicated computer (including the Raspberry Pi) that you host at your home or repeater site. It is based on the open source Asterisk PBX running the app_rpt application. App_rpt makes Asterisk a powerful system capable of controlling one or more radios. It provides linking of these radio “nodes” to other systems of similar construction anywhere in the world via VoIP.

AllStar is a busy network used worldwide. Many older 2m/70cm repeaters across the world are now connected to AllStar meaning that if you have a node you can connect to them.

The great thing about having an AllStar node at your QTH is it is an FM node, so you don’t need a digital radio to access it. In fact you most likely already have a radio that you can use.

Any FM radio with CTCSS that operates in the ham bands can access your node or an AllStar enabled repeater.

Audio quality is generally extremely good because it’s FM so it doesn’t sound “digitised” like other digital voice modes.

An AllStar RF Node such as the DuraNode is similar to the traditional “hotspot” in that it runs on a Raspberry Pi with an RF hat, and is connected to the AllStarlink network via the internet. The only difference is that the hat uses an FM radio chip, hence no need for a digital radio.

You can control your node 3 ways.

1) Via “Supermon” which is a dashboard that you can add into the node’s software and can come up on any web browser that on the same WiFi network as your node.

2) Via an App called Node Remote which is available on Android and iOS .

3) Via DTMF tones from your radio.

There are many repeater networks connected to each other using AllStar.

The VK3RBA Hub is a fine example of this.

There are also many international Hubs. These are mostly large interconnected networks.

Hubnet UK:

Founded in May 2016 by Steve M0HOY with the mandate of increasing radio activity through coordinating the linking of Repeaters and Simplex Gateways across the UK that in recent years had fallen into disuse.

Heading into its 6th year in May 2023, HUBNet has pushed the boundaries of multimode Amateur Radio communications; with a great deal of work by Peter G7RPG and the support of many others, HUBNet has rapidly become the largest multimode AllStar communications platform based in the UK. 

The East Coast Reflector network is another example.
