Uniden BC 245XLT - Manual (Page 38)

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.
