How To Join K-Link
Do you (or your club) have a repeater that you would like to link to our network?
The K-Link Repeater Network is accepting applications from interested individuals or clubs who maintain repeaters that meet the following criteria:
- Repeater is established, well-engineered, maintained and fully operational
- Has a useful coverage area for Skywarn operations, and is of value to travelers
- Does not substantially overlap existing K-Link repeaters
- Broadband internet available at the site (no dialup or satellite)
- Willing to use CTCSS or DCS access
- Is path-balanced (not an alligator)
- Users agree to abide by the Use Policy.
Prospective applicants should consider how often the repeater would be connected to K-Link.
If your repeater does not already have IRLP or Allstar, we can help you setup one of those services for the purpose of linking. While IRLP and Allstar are both Linux-based, and they are used to link repeaters over IP, they differ in some ways.
- IRLP and Allstar can take the place of a repeater controller, but Allstar does it better.
- IRLP is half-duplex when used through a reflector. Allstar can be full duplex any time as needed.
- IRLP can interpret any DTMF digit sequence (sans ‘D’) and run a bash! script upon receipt of that sequence.
- Allstar requires all commands begin with * (star). Bash! scripts can be called with DTMF.
- IRLP uses a hardware DTMF decoder so digit decoding is more robust than Allstar’s software-based decoding.
- IRLP nodes must connect to an IRLP reflector to talk to more than one node at a time. Allstar nodes can connect to any number of nodes simultaneously.
- IRLP and Allstar nodes can be controlled via web page interface.
- IRLP and Allstar nodes offer very high audio quality.
- Allstar nodes can stream to Broadcastify with no additional hardware. IRLP requires an extra USB sound fob.
- Allstar has a NWS watch/warning script to notify users of weather conditions.
- IRLP can run on the original Raspberry Pi B. Allstar requires a Pi 2 or higher.
- Allstar can interface more than one radio per server. A Raspberry Pi 2 can handle 2 radios.
- Allstar nodes can be setup as completely private, unlisted public, or public. IRLP nodes are required to be public.
For short duration or infrequent linking, we remind you that K-Link accepts connections from properly configured IRLP or Allstar-equipped repeaters and simplex nodes. In these cases we require that your node/repeater be monitored locally at all times while the link is active. This means somebody must be able to monitor what your node receiver is hearing. This is an IRLP and K-Link requirement and is non-negotiable. We can help you configure and maintain an IRLP or Allstar node if you need assistance.
- IRLP users should connect to reflector 9335.
- Allstar users should connect to our public hub 42640
Entities who would like to be linked most of the time and not be required to monitor the connection continuously, please fill out the application below.
