Location-based Scanning
Location-based scanning allows you to control which systems/sites and channel groups are scanned based
on your exact location. This frees you from having to manually enable and disable systems or channel
groups as you change location.
To use Location-Based scanning, you need to have the following:
the location for the center point for each system/site or channel group you want to control
the radius or distance from the center point you want to set as the range for each system/site or
channel group
if you are scanning while traveling, you may want to include the heading (direction) of travel
some type of mapping method. If you don't want to use paper maps, you might try a mapping
software (such as Microsoft® Streets and Trips or Delorme® Street Atlas) that allows you to draw
markings and overlays on maps.
a GPS receiver with a serial data output (NMEA)
There are many different approaches you can use to determine where to place a center point for a system/
site or channel group. The two most common are the geopolitical approach and the antenna-centric
approach. For large trunked systems, you may find that a combination of these two approaches works best.
