Uniden Multi-Site Trunking
From The RadioReference Wiki
This feature is implemented in some Uniden scanners.
Some wide coverage systems use multiple system sites that are linked together to provide extended area coverage. Each site operates on its own set of frequencies, but share talk group channels with all other sites in the system.
Normally, a site will only carry traffic for talk groups that have at least one subscriber unit (mobile radio) affiliated with it.
With the initial implementation of dynamic memory, each site needed to be entered as its own system, and all talk group channels had to be duplicated. This resulted in more complexity in programming as well as more memory usage.
Multi-Site Trunking is available for Motorola and EDACS system. With this method, you define a system, one or more sites for the system, and then the channels for the system. All channels are shared among all sites.
Here’s an outline of a Multi-Site System:
System System Attributes Site Frequencies Other Attributes Site Frequencies Other Attributes Channel Group Channel Group Attributes Channel Channel Attributes Channel Channel Attributes Channel Group Channel Group Attributes Channel Channel Attributes Channel Channel Attributes
The only System attribute is the system name. This tag is never displayed, but makes the system easy to find for programming updates.
Site attributes include:
- Site Quick Key: Equivalent to the System Quick Key; turns the site on/off for scanning.
- Site Name
- Site Location
