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.
EDACSÆsystems 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 EDACSÆtrunking systems (such as those used by some utilities) utilize a control channel that cannot be tracked with
the UBC 245XLT.
