Uniden Scanner GPS Features

From The RadioReference Wiki

Some Uniden scanners include the ability to automatically change settings and display information when connected to an external GPS receiver.

Location-Based Scanning

The scanner will automatically lock or unlock sites based on the geographic information provided by a GPS receiver.

This features requires the site or system to include the center latitude and longitude, and the range (distance) of coverage.

When the scanner is within the "circle of coverage" defined for a site or system, the scanner will automatically unlock and scan the site or system. When the scanner moves outside the "circle of coverage", the site or system will automatically be locked.

Frequently Asked Questions

How do I decipher coordinates that look like 445812.79N?

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. The BCD996T UASD uses this format, but discards the symbols. So, this same coordinate would be entered as 445812.79

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 + You would perform the reverse calculation to convert Deg to DMS.

To more easily convert Decimal Degrees to the DDDMMSS.sss format or vice versa, see the converter at this link:
