Programming EDACS System Frequencies

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
UBCT8 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, an entire department or city.
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.
