ˆ How to use this guide<br />
The data in this guide is listed alphabetically by state. The<br />
example below of a trunked system in Alabama shows:<br />
The Agency name (often local agencies, such as municipal<br />
police and fire departments, share space on one system).<br />
The system’s call sign. Then, the transmitter sites. Finally,<br />
the frequencies used by the system.<br />
MOBILE COUNTY OF WNUX634 BAYOU LA BATRE, CITRONELLE,<br />
MOBILE, WILMER 856.2625-1, 857.2625-2, 858.2625-3, 859.2625-4,<br />
860.2625-5, 854.9625-6, 855.2375-7<br />
In this example, the numbers following the frequencies<br />
indicate this is an EDACS ® system and the frequencies<br />
must be entered into the scanner in the sequence shown.<br />
Systems not marked as EDACS should be assumed to be<br />
Motorola, although this may not always be the case.<br />
“Fill-in” sites have generally been removed from the list.<br />
Refer to POLICE CALL for details. Digital (unmonitorable)<br />
systems are either marked as such or have been removed.<br />
Many systems may be licensed but not yet on the air. Also,<br />
some agencies use private trunked radio systems (known<br />
as SMRs). These are listed when known.<br />
The most important information you will need once you<br />
program system frequencies is talk group IDs. Thousands<br />
of talk group IDs can be found in the Police Call frequency<br />
and trunking guide, available at <strong>Radio</strong> <strong>Shack</strong> stores nationwide.<br />
Also ask about the new Police Call CD-ROM!<br />
Large multi-transmitter site trunking systems use several<br />
control channels. Generally, because this guide breaks<br />
down systems by transmitter site, you should program your<br />
scanner with all frequencies licensed to a site (and call sign<br />
as shown). Some systems are simulcast, meaning the<br />
same frequencies (or a subset of frequencies) are used<br />
over a wide area. You only need to program these frequencies<br />
once to hear all communications on such a system.<br />
Occasionally, system managers swap around frequencies<br />
between sites to provide the best system performance.<br />
