With the help of several people here I am learning the differences between my SDS and the 352P2 and using Proscan to practice programing a 352 before I decide to purchase one. One thing I could not figure out was if more then one GPS location can be created for one group. One particular group I want to create has a GPS location that spans my entire state when I would only be able to hear them in a small potion. They only way I could figure this out was to create multiple groups of the same and adjust the GPS.
