If you have the room in your scanner, I would strongly suggest you program the entire conventional section for the Nassau Page located in the Database.
While some departments still tone out on 46.10, then on their low band battalion frequency (or personal UHF Frequency), there are MANY departments who are NOT using 46.10, or Firecom for that matter to dispatch and tone out.
If you don't have room in your scanner to load in the entire Nassau FD Section of the database, then just work on adding the Dispatch Frequencies, or the battalion you will find yourself in on your trip.
The Nassau EDACS system really only sees FD Activity from the HazMat and Fire Marshals. The battalion talk groups are VERY quiet.
