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 specic 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.
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.
