ALL-CALL TALKGROUPS

EDACS talkgroups are carefully planned when the system is being set up. They are organized into an outline structure, with AGENCIES being the major groups, and FLEETS being the sub-groups. The very FIRST talkgroup in each level is reserved by EDACS for a very special purpose.

(1) SYSTEM ALL-CALL -- The very first talkgroup in the whole SYSTEM is always 00-000. Any transmission on that talkgroup will be heard by EVERY RADIO IN THE SYSTEM.
(2) AGENCY ALL-CALL -- The first talkgroup in each AGENCY transmits to every radio in that Agency.
(3) FLEET ALL-CALL -- The first talkgroup in a FLEET calls every radio in that Fleet.

It seems strange, but we DON'T LIST these unique talkgroup codes in the EDACS GUIDE. Why? Because they are SO SPECIAL that they are almost NEVER USED. Because they LOOK so special, users may think that they can store them to hear everything. In fact they will hear almost nothing. To help prevent this mistake, we have changed the way we show them. We now show them in RED, without the talkgroup number. Agencies are shown with " = = = " and Fleets are shown with " - - - ". This format lets you clearly see the logical outline structure of the system without being distracted by codes you may not want to use. (Of course these special talkgroups ARE used in some systems, and in some situations, so you can program them as desired. Although the talkgroup listings don't currently show the values you should be easily able to figure them out from context.)
