An EDACS® Trunked system

This chart shows how talkgroups are organized within an

EDACS system at the Agency level. The individual

talkgroups cannot be shown at this scale because there

are over 2000. However the chart can show the 16

Agencies in this example. The system is logical and easy

to understand. EDACS systems are typically arranged in

an outline structure.

The system users are given blocks of talkgroups. Sizes

vary but most large cities and other agencies have blocks

of 128 channels. Smaller cities have only 64 or 32

channels.

In this example, the County Sheriff is agency 01. The city

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, you can select a desired city by keying in the

Agency part of the AFS talkgroup. For example, in Hold

mode you can select the entire city of Sullivan with 4 key

presses , ,

(decimal key),

When you hear an interesting talkgroup, in Hold mode

capture it to your Scan List by pressing E during the

transmission.

Or hold on it by pressing

If you want to monitor the Sullivan Police Dispatch channel

(which is talk group 03-062), press , ,

(decimal key)

, , , the key. Your scanner can also work in decimal

format.

Talkgroup 03-62 in decimal format is 402. But decimal format

does not give you any information about the system

hierarchy.

For example Sullivan, in decimal, uses channels from 384 to

511. This is not as easy to remember as Agency 03. But

decimal is useful if you need to work from decimal talkgroup

lists.
