Introduction
Some Motorola, EDACS wide coverage systems, Project 25 both Phase I FDMA and Project 25 Phase II TDMA use multiple System Sites that are linked together to provide extended area coverage. Each Site operates on its own set of frequencies, but all Sites share common Talkgroup IDs (TGIDs/channels) with all the other Sites in the System.
With the initial implementation of Dynamic Memory Architecture (DMA), each site needed to be entered as its own System (BCD296D and BCD396T), so all TGID had to be duplicated for each site. This resulted in more complexity as well as higher scanner memory usage in programming multiple Systems with multiple different System Quick Keys.
With this newer method, you define a System, one or more Sites for the System with its respective frequencies, and then the TGIDs for the System. All TGIDs are shared among all Sites.
Normally, a Site will only carry traffic for a Talkgroup that has at least one subscriber unit (Mobile/Handheld transmitting radio) affiliated with it.

- The System name is never displayed, but makes the System easy to find for programming or updates. BCT15, BCT15X, BCD996T, BCD396XT, BCD996XT
- The System and Site names are toggled between on the display for the BCD325P2, BCD996P2, and both are shown on the BCD436HP, and BCD536HP models, with Favorites simply a file layer above Systems.
Primarily attributes of a Site include:
- Site Name (if only 1 you can name it the same as the System Name, if more than 1 it's up to the user whether the Site Name includes part of the system or jurisdiction or location name)
- Site Startup Key: Allows you to turn on the scanner with certain sites preemptively enabled (used to start scanner in different quick key configurations under one Favorite List or Multiple Favorite Lists; like from Home to Work and then another start-up key for Work to Home)(not necessary for all users)
- Site Frequencies: All or Control Channel and Alternate Control Channels Only
- BCT15, BCT15X, BCD996T, BCD396XT, BCD996XT, BCD325P2, BCD996P2 only
- Site Quick Key: Equivalent to the System Quick Key (SQK); turns the site on/off for scanning. (All Sites Can be on 1 SQK or utilize many) (best practice)
- Site Location: Allows you to set the scanner to scan by location and range (if you use the scanner with a GPS unit attached.)(not necessary for all users)
- Site Hold Time: Sets how long the scanner will monitor the site.
- BCD436HP, BCD536HP only
- Site Quick Key: Equivalent to the Department Quick Key(DQK); turns the site on/off for scanning.(best practice)
- All Sites Can be on 1 DQK or utilize many DQKs (Don't use the exact same DQK for Departments and Sites (unless Anytown's TGIDs only ever utilize the Anytown Site)
- DEPARTMENT is the new name for GROUP (100 DQK's) vs (10 GQK's)
- Site Location: Allows you to set the scanner to scan by location and range w a GPS, turn on Location Control and enter Range Note: Site range + Location Control range = possible listening distance sr+LCr= pld (NOT ZIPCODE that is different)(not necessary for all users)
- Hold is on the System level and not at the Department level may need each site to be in it's on system with duplicate tgids
