The basics

What it is
AllStarLink is a free network that links radio nodes over the internet. A node is a radio connected to a small computer running the AllStar software.
Node number
Every node has its own number. You use that number to connect your node to another one.
Hub
A hub is a node that many others connect to, so a group can share one conversation.
Simplex node
A node that uses one frequency, radio to radio. Local radios talk to the node, and the node passes the audio over the internet.
Repeater link
A repeater with a node attached. Everyone on the repeater can then reach the linked nodes.
Private or public
Some nodes accept connections from anyone. Others are limited to their own group. Ask the owner first.

How a call travels

  1. 1You key your radio on the node's frequency.
  2. 2The node hears you and sends your audio to the AllStar network over the internet.
  3. 3Any node linked to yours plays your audio out on its own radio.
  4. 4Replies travel back the same way to your radio.

Ways to connect

Transceive
Both sides can talk and listen. This is the usual choice for a chat.
Monitor only
You hear the other node but cannot talk into it. Good for listening in on a net.
Local monitor
Lets you hear local activity on your own node without sending it out.

Command codes are set by each node's owner. See the common ones on the commands list and confirm with the node owner.

Running a good node

Always on
A node is only useful if it stays on. Use steady power and wired internet if you can.
Voice ID
Nodes announce their call sign on a timer. Make sure it is set to your license.
Timers
A time-out timer stops a stuck radio from hogging the network.
Updates
Keep the computer updated and use a strong password.
Backups
Save your settings so a new card or computer is quick to restore.

Questions about nodes

  • No. You can use a friend's node or a repeater link. Having your own node lets you connect when you want.
