agency is then subdivided up to 16 times to provide fleet identification, and then 8
more times to identify subfleets.
For example, the complete AFS for the Police Department West District’s dispatch
channel might be 01-062. 01 identifies the agency as the police department, 06
identifies the fleet as the West district, and 2 identifies the subfleet as the dispatch
channel. While these assignments are somewhat arbitrary and vary from system to
system, there are many resources on the web for finding the assignments for most
systems. Because of the logical hierarchy of the AFS system, your UBCD996T lets
you assign wildcard ID’s that let you, for example, use only one ID memory to
identify all units in either an agency or a fleet.
— (Single Channel Autonomous Trunking) systems operate on a
single channel and alternate control data with analog voice traffic. While your
UBCD996T cannot track ID’s in this system, it can eliminate the control data so that
all you hear is the voice transmissions when you monitor this type of system.
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 control information as digital
sub audible data that accompanies each transmission, so there is no separate
control channel. Users on an LTR system are assigned to specific talk groups, which
are identified by the radio as six digit numbers.
These numbers are in the form AHHUUU, where:
A = Area code (0 or 1)
H = Home repeater (01 through 20)
U = User ID (000 through 254)
When the scanner receives a transmission on a channel set to the LTR mode, it first
decodes the LTR data included with the transmission. In the ID search mode, the
scanner stops on the transmission and displays the talk group ID on the display. In
the ID scan mode, the scanner only stops on the transmission if the LTR data
matches a talk group ID that you have stored in the talk group ID list and have not
locked out. LTR systems are frequently programmed so that each radio has a
unique user ID.
