How to use the KI5TLZ Allstar Repeater in Rexburg

447.500 MHz, -5 MHz offset, 100.0 Hz CTCSS Tone

If you are near the Rexburg Idaho area, please feel free to use my repeater. BYU Idaho students have priority use.

For more information about the construction of the node, please refer to my short AllstarLink Node Construction write-up.

Current Connections

Node Bubble Chart

Basic commands

  • *70 -- To check the status of the node (See if the node is connected to other nodes)
  • *806 -- Disconnects connected nodes. Do this before connecting a new node.
  • *1 [node number] -- Disconnects a specific node number
  • *3 [node number] -- Connects to a node number (DO NOT CONNECT TO A NODE WITHOUT DISCONNECTING FROM ALL OTHER CONNECTED NODES)

A Few Common nodes

Before you connect to the nodes bellow, Don't forget to disconnect from other nodes (*806).

To connect to BYU Provo, you would hold your PTT button and then type " *3536263 ". When you let go of the PTT, you should hear a beep and then a voice that says "Node 536263 Connected!".

Rules of Use

  1. Be courteous to other users of the system -- If it seems like it could be a bad idea or would interfere with others, DO NOT DO IT.
  2. Do not make more than one connection at a time
  3. Listen before you call.
  4. Enjoy and share the system. It is open to anyone!
  5. Refrain from connecting to long nets without prior permission from KI5TLZ.
  6. THIS IS THE MOST IMPORTANT RULE: Use common sense!

Why only one node connection at a time?

Many other allstar networks prohibit multiple connections from connected nodes. We could unintentionally connect 2 repeaters and be broadcasting a net from a small Alabama repeater out to the entire state of New Mexico (Yes, I speak from experience). The owners of the other nodes can BAN our node from connecting to theirs if we cause too much of a ruckus.

To check the status of the node, click the picture at the top of the page. It should show the current connections in the node.
