Just about all of Suffolk County NY Public services are on Motorola Type II. Easist way is to set it up is download Freescan and get it working on your computer. So you can talk to your radio. Then get a premium membership to radio reference. Then go to their web site Radio Reference Database and download the Suffolk County Public SMARTZONE system to your software and load it up to your radio.
Give yourself sometime to set up. When you have problems trying to connect to the radio using freescan use wiki reference - has lots of info to help you. If your computer does not have rs232 then you need to puchase special cable USB for you radio. Cna buy on internet about 30 bucks
There must be over 100 talk groups. Each group represents a different agency. The Database has all the talk groups and text tags. I would not want to enter all of them manually.
Once set up. When scanning and scanner is trunking in ID scan Mode when 7th precinct shows up press hold and your radio will stop and trunk on this ID alone.
Also Suffolk is supposed to reband very soon and when it does You will need to download again from Radio Reference after the changes are in. Or make changes manually.
Most important if you wish to do it manually you need the Trunking setup information
