Programming EDACS System Frequencies
®
TrunkTrackerIII now allows tracking of EDACS® trunked systems. Until now these widely
used systems have been almost impossible to monitor with a conventional scanner.With
yourTrunkTracker III listening to EDACS(s) is remarkably easy, and perhaps even easier
than conventional scanning.
EDACS systems use 'TransmissionTrunking', which means that each transmission is
assigned a new frequency.As the conversation moves through the system's frequencies,
yourTrunkTracker III automatically follows it.
This chart shows a 30 second sample of EDACS transmissions. Eight differenttalkgroups
are using the system as their transmissions switch between the thirteen system frequencies.
Notice how the dotted line shows talkgroup02-023 moving from channel to channel. Your
UBCT8 can clearly and automatically follow this talkgroup,or any other, as you select.
EDACS systems are organized in a logical way that keepsrelated talkgroups together. Your
scanner is designed to takemaximum 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, an entire departmentor city.
When you program EDACS frequencies, it is critical that you store each one in the
CORRECTLOCATION. By the nature of EDACS systems this is necessary for tracking. This
oftenis not the frequency order, so you must be sure you have the right sequence.
