EDACS Tracking

TrunkTracker II 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 II listening to EDACS 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 II automatically

follows it.

This graph depicts a 30 second sample of transmission in

an EDACS trunked system, showing the frequency

transitions that a particular radio conversation might use.

Note: Many 900 MHz EDACS

trunking systems (such

as those used by some utilities) utilize a control

channel that cannot be tracked with

the BC 245XLT.
