A TrunkTracker is a special scanning receiver which has been programmed to decode, monitor, and track communications on a Trunked Radio System. TrunkTracker technology was developed by Uniden back in 1997 and was the biggest advancement in scanner technology in 20 years. Since it's arrival, trunking technology now spans four generations from the original TrunkTracker models to the current TrunkTracker IV models.

TrunkTracker - the first TrunkTracker scanners (BC235XLT, BC895XLT, PRO-90, PRO-91, PRO-2050 and PRO-2066), could only monitor Motorola systems in the 800MHz frequency band and only one system at a time.

TrunkTracker II - TrunkTracker II expanded monitoring capabilities of trunked systems to include Motorola Type I, Type II, Hybrid, SMARTNET, Privacy Plus, GE/Ericsson EDACS systems (which is now owned by M/A-Com) and systems located in the VHF/400/500/ 800/ 900 MHz frequency bands. Another major improvement was "Multi-Track", giving uses the ability to not only monitor both non-trunked conventional and trunked systems at the same time, but multiple trunk systems as well. The BC245XLT is the only TrunkTracker II scanner made.

TrunkTracker III - TrunkTracker III technology adds the ability to monitor EF Johnson LTR systems along with the ability to monitor EDACS 4800, 9600 and SCAT* analog systems. TrunkTracker III scanner include the BC780XLT, BC246T, BC898T, BC785D and BC250D - BCT-8?. *(EDACS SCAT is only available in the BC785D and BC250D).

TrunkTracker IV - TrunkTracker IV technology adds the ability to monitor APCO 25 Digital Trunking Systems including 3600 & 9600 Baud, C4FM, & CQPSK.------------->
