Understanding Scanning
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.
I-Call (Motorola/EDACS)
I-calls are direct unit-to-unit transmissions that are not
heard by other system users. Your BC246T can receive
I-call transmissions. See “Setting I-Call (Motorola and
EDACS Systems Only)” on Page 68 for more
information about monitoring I-call transmissions.
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. TheInternet 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:
• http://www.scannermaster.com * - frequency
resources and home of Police Call.
You can also call them at 1 800 SCANNER (hours are
from 10:00 a.m. to 5:00 p.m. Eastern Time Monday
through Friday).
