Hint: While searching, you may not know exactly to whom the talk group IDs are assigned until you listen
awhile. To locate talk group ID lists for your local police, fire, and other agencies, refer to frequency guides
available at your local RadioShack store or on internet sites such as www.trunkscanner.com. You can also
determine the type of agency you are listening to after a short while, be it a police, fire, or emergency medical
2-way radio user. Once you have identified the type of service, note the associated talk group ID of that unit
for future programming. See "Identifying a Trunked Frequency" on Page XX. Determining the service
associated with a talk group ID might take awhile, but discovering the ID owner of each signal is half the fun of
trunk scanning!
