Tracking
TrunkTracker III now allows tracking of EDACS
®
trunked
systems. Until now these widely used systems have been
almost impossible to monitor with a conventional scanner.
With your TrunkTracker III listening to EDACS(s) is
remarkably easy, and perhaps even easier than conventional
scanning.
EDACS systems use 'Transmission Trunking', which means
that each transmission is assigned a new frequency. As the
conversation moves through the system's frequencies, your
TrunkTracker III automatically follows it.
This chart shows a 30 second sample of EDACS
transmissions. Eight different talkgroups are using the system
as their transmissions switch between the thirteen system
frequencies.
Notice how the dotted line shows talkgroup 02-023 moving
from channel to channel. Your BC250D can clearly and
automatically follow this talkgroup, or any other, as you select.
EDACS systems are organized in a logical way that keeps
related talkgroups together. Your scanner is designed to take
maximum advantage of this organization to make your
scanning easy. It lets you zero in on just the part of the
system you want to hear, whether it is an individual channel
or an entire department or city.
Programming EDACS System Frequencies
When you program EDACS frequencies, it is critical that you
store each one in the CORRECT LOCATION. By the nature
of EDACS systems this is necessary for tracking. This often is
not the frequency order, so you must be sure you have the
right sequence. Sources for this information can be found at
