Set LocationInfo
Use this menu to configure geographic information for each system or site. With this
information and a standard NMEA GPS input, the scanner can automatically change
which systems, sites and channel groups it scans as you change location. You must set
the location information if you want to use Location-based Scanning.
Set Latitude and Set Longitude
Enter the latitude and longitude of the center of this system or site. You can use any
geographical coordinates as the center, but most often it will be the physical location of
the antenna, the center of a city, county, or other geopolitical territory, or some
combination of the two.
Geographical coordinates can be represented in a few different ways. The two most
common representations are DMS and Deg.
DMS breaks the coordinate into Degrees, Minutes, and Seconds. This is typically
represented like: 44° 58' 12.79" N. Your scanner uses this format.
Decimal degrees simply use the degrees expressed as a decimal number. 44° 59' 12"
equates to 44.97381 Degrees. Mathematically, you can change DMS to Deg using the
formula DDD + MM/60 + SS.ss/3600. You would perform the reverse calculation to
convert Deg to DMS.
To more easily convert Decimal Degrees to the DDD° MM' SS.sss" format or vice versa,
see the converter at this link.
Set Range
Enter the maximum distance from the center that this site or channel will be active. As
long as your position is within the radius you enter here, the scanner monitors this site or
channel; when you leave the channel range, the scanner locks out this site or channel.
The scanner treats the number you enter here as miles or kilometers depending on the
value you selected in the Set Unit field in the Set GPS Format menu (under the main
Settings menu). Enter a range from 0.5 through 125.0 mi/km, in 0.5 mi/km steps.
