9. Examples of how you might use AFS are shown above in the description of an EDACS trunked system and elsewhere in this manual It is very easy to use Be sure to become familiar with AFS Partial Entry and your scanning will become far more flexible and efficient Emergency Call Alert Your BC250D alerts you when an EDACS Emergency transmission occurs 66 EDACS systems often provide users with an Emergency mode on their radios Users in trouble can alert the dispatcher and other units and get priority access to e XE When a user activates Emergency mode i i flash the display during the entire transmission At the beginning of each transmission it will sound a distinctive emergency alert tone three times To turn Alert ON OFF enter into the Menu mode Select VFO and pressing E Patch Tracking The BC250D can follow EDACS patched talkgroups EDACS systems sometimes bring several talkgroups together in a Patch A patch might be used by a police agency at night to provide a single channel with a single dispatcher for a wide area A patch is created when a single temporary talkgroup substitutes for the original talkgroups While the patch is running which may be for hours or days the original talkgroups cease to be used If you were monitoring one of these talkgroups you might think there was no traffic but in fact the talkgroup was operating at the different temporary number If a talkgroup in your

12. 30 EDACS systems are organized in a logical way that keeps related talkgroups together Your scanner is designed to take maximum advantage of this organization to make your scanning easy It lets you zero in on just the part of the system you want to hear whether it is an individual channel or an entire department or city Programming EDACS System Frequencies When you program EDACS frequencies it is critical that you store each one in the CORRECT LOCATION By the nature of EDACS systems this is necessary for tracking This often is not the frequency order so you must be sure you have the right sequence Sources for this information can be found at scanner uniden com 64 An EDACS Trunked system This chart shows how talkgroups are Abs organized within EDACS system 00 at the Agency level The individual 4 talkgroups cannot be shown at this 01 COUNTY SHERFE 200 scale because there are over 2000 ESTAS 300 However the chart can show the 16 92 _ AMBULANCE Agencies in this example The system is suva mi logical and easy to understand EDACS systems are typically arranged u outline structure Imm 05 RANORA FORD 700 TROUBLE CREEK The system users are given blocks of J F 800 talkgroups Sizes vary but most large 06 cities and other agencies have blocks _ 128 channels Smaller cities have only j 1000 64 or 32 channels E

106. talkgroups are assigned specific IDs When someone in a talkgroup uses their radio a brief burst of data is broadcasted before each transmission The trunking system computer uses this data to temporarily assign each radio in a talkgroup to an available frequency If the group using a frequency stops broadcasting or pauses between replies for a few seconds they are removed from the 7 frequency so another talkgroup can use it Sharing of the available public service frequencies or trunking allows cities counties or other agencies to accommodate hundreds of users with relatively few frequencies Following a conversation on a trunked system using a scanner is difficult if not impossible Because when there s a short break during the conversation you re monitoring it s possible that the talkgroup will be assigned to a completely different frequency in the trunked system This type of scanning is difficult and frustrating TrunkTracker III changes this Not only does your new BC250D scan channels like a conventional scanner it actually follows the users of a trunked radio system Once you know a talkgroups ID you won t miss any of the action If you re a new scanner enthusiast you may want to read the first part of this manual and use your scanner in conventional mode before you begin trunk tracking Understanding scanning fundamentals and its terminology will make trunk tracking much easier A glossary of other commonly used te
