Uniden Multi-Site Trunking

Introduction

This feature is implemented in the BCT15, BCT15X, BCD996T, BCDx96XT, and P2, branded Uniden trunking scanners.

Some Motorola and EDACS 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 common talk group channels with all other sites in the system.

With the initial implementation of dynamic memory, each site needed to be entered as its own system, so all talk group channels had to be duplicated for each site. This resulted in more complexity in programming as well as more memory usage.

With this method, you define a system, one or more sites for the system with its respective frequencies, and then the talk group IDs for the system. All IDs are shared among all sites.

Normally, a site will only carry traffic for talk groups that have at least one subscriber unit (mobile radio) affiliated with it.

Here’s an outline of a Multi-Site System:

• The System tag is never displayed, but makes the system easy to find for programming updates.

Primary Site attributes include:

• Site Name
• Site Quick Key: Equivalent to the System Quick Key; turns the site on/off for scanning.
• Site Startup Key: Allows you to turn on the scanner with certain sites enabled to scan different areas.
• Site Frequencies
• Site Hold Time: Sets how long the scanner will monitor the site.
• Site Location: Allows you to set the scanner to scan by location and range if you use the scanner with a GPS unit attached.
