Limit Search Object (LMIT)
A Limit Search Object (LMIT) is a search object that stores the parameters
necessary for the radio to search each frequency within a lower and an
upper limit for activity. A LMIT object can be used for standalone searching
- the radio just searches and stops when activity is detected on a frequency,
or for searching that is performed while the radio is scanning. The radio
treats LMIT objects just like any other Scannable Object when in Scan
Mode. If you create a LMIT object, assign it to a Scan List and press the
SCAN key, the radio will check for activity on all the Scannable Objects
- TGRP objects, CONV objects, and even LMIT objects. An example of
when this might be handy would be when you want to scan for activity
on a collection of TGRP and CONV objects, then run through a range of
frequencies to look for activity there, such as the entire 2 meter amateur
radio band or the entire VHF marine radio band. When used in Scan Mode,
this capability is best suited for small ranges of frequencies that contain
more frequencies than practical to program as individual channels. Any
size range can be used, but larger ranges that take more time to search will
increase the chances of missed activity on other object types.
Essential Limit Search parameters
Much like the other object types, there are only a few parameters that are
essential in order for a search range to function correctly. The
FrLO:
and
FrHi:
lower and upper frequency limits must be specified, so the
scanner will know where to begin the search, and where to end the search
and start again. The
Mode:
must be set properly, although by default the
scanner will automatically choose the receive mode that most likely applies
to the active frequency as the search proceeds. And again, we recommend
that you give the LMIT object a name in the
Tag:
field so that you can
easily find or identify it later.
To create a new LMIT object, press PROG to place your scanner into
Program Mode, then press the
NEW
softkey, then press the
SRCH
softkey
to view the available Search types, then press the
LMIT
softkey. Use the
data entry methods you have already learned for CONV and TGRP object
setup to specify the
FrLO:
and
FrHi:
limits, and provide a name for
your search in the
Tag:
field. When finished, press the
Save
softkey to
store your LMIT search as a new object.
Once your LMIT object is saved, you can use it while scanning, or launch
the LMIT search by itself by pressing the
SRCH
softkey (note that we are
referring to the
SRCH
softkey, and not the SRCH key on the keypad) after
navigating to the LMIT object in Manual Mode.
