SUPERLINK Repeater Linking System

SuperLINK is an operator controlled Amateur Radio repeater linking system connecting 2 meter repeaters located along Interstate 94 from the Western Border of North Dakota, through Minnesota and into Wisconsin. It also has links which go north to Winnipeg, Canada.

The SuperLINK linking system requires that the user turn on the linking system of their local 2 meter repeater and then select where the linked signal will come out of the system. This selection is done by the system user sending out two 3 digit DTMF codes. A voice announcement will tell you when you have successfully completed the linking.

Rules of Operation

  1. Remember the priority of traffic on the linking system. Emergency (#1), weather (#2), and general conversation.
  2. Be sure you turn off what you turn on. Turn off the links in the reverse order you turned them on, so that you can listen for the voice announcements to tell you when each has been cleared.
  3. Be sure you leave time (1 or 2 seconds), after keying your transmitter, for the system to come up before you start talking or sending DTMF node codes.
  1. Access the 2 meter repeater in you local area and ID.
  2. Indicate your intentions of accessing the SuperLINK.
  3. Enter the node code for your local repeater using your DTMF pad.
  4. Listen to hear the link acknowledge your access.
  5. Listen for anybody else using the SuperLINK.
  6. If the link is clear, enter the node code for the destination repeater.
  7. Listen to hear the link acknowledge your access to the destination repeater.
  8. Listen for anybody using the destination repeater.
  9. If the destination repeater is clear then make your call.
  10. Wait about 2 seconds before talking each time you key your mic. This will allow the link to connect all nodes used in your communication.
  1. Key in the number 1 and then the node code for the destination repeater.
  2. Listen to hear the destination repeater acknowledge your request.
  3. Key in the number 1 and then the node code for your repeater.
  4. Listen to hear your repeater acknowledge your request.

How to dial Node Codes

Node codes are dialed by transmitting the first three digits of that city using your transceiver’s DTMF keypad. For example: BISmarck = 247, ALExandria = 253.


The Barnesville Hotlink is a cluster of 3 permanently links repeaters connected to SuperLINK:

  • Barnsville
  • Fischer
  • Karlstad

The Barnesville Hotlink node code is 327, for FAR (Fargo). This is because BAR would conflict with CAR (Carrington) which is 227.


Winnipeg is not a traditional SuperLINK node, but rather a dial up extension of the Barnsville Hotlink. Winnipeg acts differently than the rest of the system.

  • From any of the Barnesville Hotlink systems enter 946 (WIN) to enable the Winnipeg link.

  • From any other SuperLINK node follow the standard connection procedure (documented below) to enable the link from your repeater to the Barnesville Hotlink, and then enter 946 (WIN) to enable the Winnipeg link.

Also note that the disconnect code for the Winnepeg link is 947 and
