The Basics

LTR mode

You can set your scanner so it decodes the talk group IDs used with LTR systems. This setting is called the LTR mode.

LTR frequencies are organized in a speciﬁc order. Each frequency is assigned a Home Repeater Number (HR). For the scanner to correctly switch to an active frequency, you must program the frequencies in HR order, starting with Memory X01 in the selected bank.

Your PRO-97 scanner features a new tool to help you determine the correct channel mapping for LTR system frequencies. The scanner’s LTR Repeater Finder displays the current Home Repeater when monitoring LTR transmissions in manual mode.

To determine the correct Home Repeater programming, enter the system channels of an LTR system in any order. Be sure to program the mode for each LTR channel to LT. Listen to each channel one at a time in manual mode and watch for the decoded LTR data at the bottom of the scanner’s display. When an LTR transmission occurs, you should see the LTR talkgroup information on the bottom line of the display, and a number preceded by “R” in the bottom right hand corner (i.e., R12). The “R” number is the Home Repeater number that the current transmission is occurring on. To correctly program this Home Repeater number into your scanner, be sure that the channel number in the bank is equal to the number that is displayed after the “R”. For example, if you see R12 displayed on a particular LTR frequency, that frequency needs to be programmed into Channel 12 of

the current bank in order to track the LTR system activity properly.

LTR 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
