Understanding GPS Scanning
Programming based GPS scanning requires that the Systems, Sites, and Groups (or Favorites Lists) be programmed with GPS coordinates and ranges. The GPS sends the location to the radio and when the radio determines that you are within the circle drawn based on the location and range it turns on that item. When you leave the circle it turns it off.
If you use your scanner over a wide area a GPS can allow you to automatically turn on and off systems, sites, groups, and/or Favorites Lists automatically and without having to punch in a ZIP Code all the time. If you only use the scanner at home or around a small area a GPS wouldn’t help you but if you travel a lot (RV folk, truckers, etc.) it can be invaluable.
