If you're monitoring a trunked system, such as Tulsa Fire for example, you only need to program in the control channels, which are listed in the RR database. Then you set up the talkgroup ID's for the agencies you wish to monitor and listen to that bank on Closed mode to hear only those ID's. If you listen to it on Open mode for that bank, you will hear everything on the system, including some you may not want to hear, such as public works, etc. Hope this helps you out.
Like OkRob said, you need the freqs for Tulsa and then put in the talkgroup IDs you want to hear. Example.
For the City of Tulsa Fire Department
You need to program into your scanner the following (check your manual to see how/if you need to do the following):
Set a bank to the type of 800MHz trunked system. For Tulsa it is a Motorola Type II SmartZone.
Next, put in your frequencies for that system. For Tulsa, you need to put in the following:
856.46250, 856.76250, 856.93750, 856.96250, 856.98750, 857.46250, 857.76250, 857.93750, 857.96250, 857.98750, 858.46250, 858.73750, 858.76250, 858.93750, 858.96250, 858.98750, 859.46250, 859.73750 , 859.76250, 859.93750, 859.96250, 859.98750, 860.46250, 860.73750, 860.76250, 860.93750, 860.96250, 860.98750
Afterwards, you need to program in the talkgroup IDs you want to hear. For Tulsa Fire, you probably want their dispatch, plus at least each fire district. So in you scanner (again, refer to the manual if need be), put in the following talkgroup IDs. If you have the ability to use alpha numerics on the label, I would suggesting tagging on the name of each talkgroup.
Talkgroup - Name Tag
35856 - TFD 6A MAIN
35920 - TFD 6C D1
35952 - TFD 6D D2
35984 - TFD 6E D3
36016 - TFD 6F D4
36048 - TFD 6G D5
Finally, refer to the manual on how to set than bank on the scanner to open or closed mode. Open mode will scan all of Tulsa's freqs and pick up any talkgroup that is keyed up (in turn, it should display the talkgroup ID). In closed mode, the scanner should only pick up talkgroup IDs you have programmed in (such as TFD). You can usually also lock out a talkgroup ID in case you want to program it in but not listen to it all the time.
I have all of TPD programmed into my scanner but I keep most of their side channels locked out since I don't really need to hear anything but their dispatch, but I can unlock one of those channels if they switch over to it (i.e. if they switch to a tactical).
Hope that made some sense.
