Ahhhhhhhhhhhhhh well the easiest way would be to contact the communicatons director for the county or who ever programs the counties radios. They should be able to get them for you. The other way, which is time consumming and process of elimination, is to download ComTekk 2-Tone Decoder II and have that running on your computer while a scanner or radio is hooked up to it and when a tone goes out it will log it> at the end of the day if your station went on a call the tones will be logged and you can match it to the time of the call. In some areas, such as where i am, that would be hard to do beacuse we always dispatch multiple stations to calls so there is alot more involved in figuring out which one goes to what. But like i said the best way is to contact who ever it is that programs your radios.
