Setting the Delay Mode for Trunking Mode
A default delay of 2 seconds is automatically set for each talkgroup for ID Scan mode and ID
Search mode. To set the delay feature on or off, press 
DELAYwhile trunking, “DLY” will
appear or disappear depending on your setting.
Trunking Frequency Confirmation
You can check the frequency while a talkgroup ID is active.
Press the 
key ,and the active frequency on which the talk group is transmitting will flash on
the display. Or press and hold the 
key for 2...

Multi-Track
The BCT8 allows you to track more than one system at a time. Here are some highlights of
this feature:
❖You can actually track up to 5 trunking systems at one time.
❖You can trunk scan, or search and scan conventional frequencies at the same time.
❖You can program conventional frequencies in the same bank as trunking systems.
After the scanner finishes checking a trunked system for activity, it will conventionally
scan the other frequencies in the bank (remember, only trunking frequencies...

EDACS®Reception
EDACS®Tracking
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 systems frequencies,
your TrunkTracker III...

An EDACS®Trunked system
This chart shows how talkgroups are organized within an
EDACS system at the Agency level. The individual
talkgroups cannot be shown at this scale because there
are over 2000. However the chart can show the 16
Agencies in this example. The system is logical and easy
to understand. EDACS systems are typically arranged in
an  outline structure.
The system users are given blocks of talkgroups. Sizes
vary but most large cities and other agencies have blocks
of 128 channels. Smaller...

Special EDACS®Features
AFS Partial Entry Feature
AFS is Unidens method of encoding EDACS talkgroups. 
AFS stands for Agency-Fleet-Subfleet.
AFS talkgroups are used in all EDACS reception -- in ID Search, ID Lockout and ID Scan. The
powerful AFS Partial Entry feature designed into the BCT8 lets you use either a complete
talkgroup code, or just the most significant part.
This feature lets you expand or narrow searching and 
scanning to one of 4 levels. By entering only the desired part
of an AFS...

LT R®Reception
LT R®Tracking
LTR®(Logic Trunked Radio) systems are trunking systems used primarily by business or
private communications service providers, such as taxicabs, delivery trucks, and repair
services. These systems encode all trunking information as digital subaudible data that
accompanies each transmission. Users on an LTR system are assigned to specific
talkgroups, which are identified by the radio as six digit numbers. 
These numbers are in the form AHHUUU, where:
A= Area code (0 or 1)...

Motorola Reception
Motorola Tracking
There are really two types of Motorola trunking systems. These are usually referred to as
Type I and Type II systems. Type I only occurs on some 800 MHz systems. All VHF and
UHF trunking systems use Type II.
One important distinction between these two systems is the amount of data transmitted by
each radio when its push-to-talk button (
PTT) is pressed. Every radio in a trunked system is
assigned a unique ID so the central site computer can identify it when it’s...

Fleet Map Programming
If you have programmed a trunk tracking bank for Motorola, press TRUNKto start Multi-
Track, and you will see user IDs on the display. Since the BCT8 defaults to Type II systems,
all the IDs will appear as numbers. However, if you notice a mix of odd and even user IDs,
for example 6477, 2560, 6481, 6144, 1167, etc., then you are probably monitoring either a
Type I or Hybrid systems. 
You may also notice that you are missing responses when you hold on an active ID. Unlike
Type II,...

The next available block appears on the display.
6. Repeat step 5 until you have selected a size code for each
block.
For details about each size code, see Fleet Map Size Codes
in the Appendix.
Programming a Hybrid System
A Hybrid system is simply a Type I system with some blocks designated as Type II blocks.
To program a Hybrid system, follow the steps listed in Programming a User Fleet Map in
the previous section. However, if you want a block to be Type II, select Size Code  .
When you begin...

9.  Use the keypad to enter a new Offset Channel, then press E.
Note:•You can only input within a range of 380-759.
•If the system is not tracking properly, you may need to
try a new Base Frequency or Offset Channel, or you
may be missing frequencies from the system.
•You can set up to three Base, Spacing and Offsets for Motorola VHF/UHF trunked
systems.
Toggling the Status Bit
On Type II trunking systems there is a method by which specialized types of communications
utilize unique talkgroup numbers. An...
