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.
Where To Get More Information
By itself, this manual really only provides part of what you need to know to have fun scanning – how to program and use the scanner. The two included conventional and trunking frequency guides will give you a good head start on the other part of what you need to know – what fre- quencies have interesting content.
Information On The Internet
The Internet is a great source for current frequencies and information about scanning. Many web sites have lists of frequencies for your area. You can use a search engine to find and use them.
Make a list of the agencies you want to listen to, then look up the frequencies and systems used by those agencies. Here are a few useful sites:
