would be when you want to scan for activity on a collection of
TGRP and CONV objects, then do a quick sweep for
transmissions from nearby transmitters.
Essential Spectrum Sweeper parameters
Like every other object type, there are certain parameters in a
SWPR record that are essential in order for the SWPR object to
function correctly. By default, a newly created SWPR object is
ready to go without any changes. In its default configuration, the
SWPR object will sweep through all of the important land mobile
radio bands and look for strong signal activity from nearby
transmitters. As you become more familiar with SWPR operation,
you may wish to include or exclude some bands in your sweeps
to check other frequency ranges or to limit the amount of time the
scanner spends sweeping frequency ranges where local
transmitter activity is less likely. This will speed up operation, and
when used while scanning, will allow the radio to return to
scanning for activity on CONV, TGRP and other enabled objects.
To create a new SWPR object, press
PGM
to place your scanner
into Program Mode, then press the
SRCH
softkey to view the
available Search types, then press the
SWPR
softkey. By default
the SWPR parameters are set for a general purpose sweep of all
important land mobile radio bands. Optionally, you may wish to
toggle the
Type:
field from All Bands to Public Safety by
pressing
"
on the 5-way pushbutton pad. When Public Safety is
selected, the frequency sweep will be limited to those frequency
ranges typically used for Public Safety communications. Note
that other radio services also use these ranges, so don
!
t be
surprised if you occasionally hear activity that is not Public Safety
related. Be sure to provide a name for your SWPR object in the
Tag:
field. When finished, press the
Save
softkey to store your
SWPR search as a new object.
Once your SWPR object is saved, you can use it while scanning,
or launch the the Spectrum Sweeper object by itself by pressing
the
SWPR
softkey after navigating to the SWPR object in Manual
Mode.
When the SWPR object stops on an active frequency, the display
will appear as follows:
