LTR Trunking Setup
LTR systems assign each frequency a Home Repeater (HR) number
and are frequently programmed with unique ID codes for each
radio. LTR Talk Group IDs are organized in a specific order, and to
scan, you must program the frequencies in HR order. LTR systems
are used primarily by businesses, such as taxicabs, delivery trucks,
and repair services.
LTR systems use a Home Repeater as part of their Talk Group ID.
Note: For information about saving frequencies into
channels, refer to “Defining a Channel” on page 17.
To save a correct Home Repeater:
1. Save the LTR channels in any order.
2. Set the bank to Open mode.
3. Manually select LT channels and watch the LTR data on the display.
Your scanner displays the LTR Talk Group ID and a number
preceded by
“R.”
The
“R”
number is the Home Repeater number
for the transmission.
4. The assigned Home Repeater channel must equal the Home
Repeater number. For example, R12 must be programmed into
Channel 12.
Searching for Talk Group IDs
If you tune the scanner to an active Motorola control channel, the
Motorola System ID and the approximate control channel message
decode success rate appears. This helps you identify the system
and the reception quality. When the scanner decodes control
channel data from a Motorola system, COTRL appears on the
display.
To search for Talk Group IDs:
1. Set the bank to Open mode.
2. Press SCAN. The scanner scans through all unlocked channels
in the active banks.
3. When the scanner stops on a transmission, press TRUNK. The
scanner displays the ID location:
Sub-bank. ID Location
0-4 00-29
Example: 2-01
Note: If the ID has already been saved,
“ID was saved”
appears. If you try to store more than 150 talk group IDs in
a bank,
“Memory Full!”
appears.
Saving a Talk Group ID
Each of the 10 banks contains 5 sub-banks that each hold 30 Talk
Group IDs. (You can save up to 1,500 Talk Group IDs.) When the
scanner receives a trunked transmission, it searches the associated
sub-bank for the Talk Group ID to decode data for Motorola,
EDACS, and LTR systems.
To define a Talk Group ID:
1. Press PROG, then press TRUNK to enter the ID program mode.
2. Press FUNC, then use S or T to select a bank.
3. Repeatedly press MODE to select a trunking mode (Motorola,
EDACS, or LTR).
4. Repeatedly press TRUNK to select the sub-bank.
5. Press S or T to select the location where to store the Talk
Group ID.
