of Sullivan is Agency 03. Adams Hill and Matthew Junction 
share Agency  08. 
Your scanner shows EDACS talkgroups in AFS (Agency- 
Fleet-Subfleet) format. This helps you see, at a glance, 
who you are monitoring. And with the partial-entry feature 
you can easily include nearby, related channels in the 
same Fleet or Agency. You can just as easily exclude 
entire unwanted Fleets and Agencies. 
When in Search mode, with the system frequencies 
programmed, and your scanner locked to the control 
channel,...

talkgroups, or a single talkgroup. 
For example, you could program every talkgroup in a police 
department with just 4 key presses. You can use the AFS 
Partial Entry feature anywhere you need to specify EDACS 
talkgroup. 
Your 20-426 can also enter or display EDACS talkgroups in decimal format \
(0-2047).

LTRR Reception 
LTRR Tracking 
LTRR (Logic Trunked Radio) systems ar e trunking systems used primarily by 
business or 
private communications service providers, such as taxicabs, delivery trucks, 
and repair 
services. These systems encode all trunk ing information as digital subaudible 
data that 
accompanies each transmission. Users  on an LTR system are assigned to 
specific 
talkgroups, which are identified by  the...

and Type II systems place radios (or radio users) into groups, called talkgroups, 
and these 
talkgroups are also assigned unique IDs.  Some radios have access to only one 
talkgroup, 
while others have access to many talkgroups. The talkgroup(s) each radio can 
access is 
called the radio’s affiliation(s). 
In a Type II system, when someone uses  their radio, only the radio ID is 
transmitted when 
PTT is pressed, whereas in a Type I system the radio ID and its current 
affiliation are both 
transmitted...

Even though there are many Type II systems, Type I systems are still in use. 
There are also 
Hybrid systems which are a combination of both Type I and Type II. Your 
scanner defaults 
to monitor Type II systems, but its possible to select a Preprogrammed Fleet 
Map or create 
a Custom Fleet Map for your area. 
For VHF and UHF Type II trunking system s, you will need to know the base, 
spacing 
frequencies and offset channels. See page 45 for details. 
Fleet Map Programming

Note: You will now begin to see Type I Fleet-Subfleet IDs. For 
example, 100-12, 100-9, 000-12, 400-8, etc. 
See User Defined Fleet Maps in the Appendix for 
more information about Type I IDs. 
How do you know if the preset map is correct? You will have to listen to see if 
youre 
following complete conversations. If not, you should try another preset map.

VHF/UHF Trunked Systems 
To properly track Motorola VHF and UHF trunked systems, you must enter 
what is known as 
the Base, Spacing Frequencies and Offset Channels for each system. 
To find these out, check the scanner.Radio Shack.com or www.trunktracker.com 
and other 
web sites and frequency resources. 
To enter the Base, Spacing Frequencies an d Offset Channel: (You can set up to 
three sets 
of these, but almost all  systems only use one set)

mode, you 
never need to worry about missing these transmissions. If you have 
programmed talkgroup 
33264 into Scan List memory, for example, and there is an emergency call 
within the group, 
you will hear it on 33264. 
The only time you may wish to turn Status Bits OFF is if youre trying to figure 
out the proper 
Fleet Map of a Type I trunking system.
