Another Expert Menu item is AudioBoost. This pumps up the audio on that channel by 6dB. Since some
systems use lower modulation levels than others, this will allow you to adjust weaker audio to match the
rest of the channels.
Lastly there is a Hit Count item in the Expert Menu. This allows you to keep track of how many times that
particular channel received traffic.
Similar methods are used to program
Trunked Talkgroups
. First however you need to program the actual
T
runked System
unless you already have it programmed and stored in the radio. When you select TGRP
(Talkgroup) the next menu allows you to select an existing Trunked System or create a new one. Select
New and you will be able to scroll thru the various trunked types until you come across the type you want.
Scroll down once more and you can label the system with a descriptive name. One more scroll down and
you can start entering frequencies used by that system. Remember that on standard 800 and 900 MHz.
Motorola systems and P25 systems you usually only need to enter the Control Channels. EDACS and LTR
systems not only need all the channels used by the system but they have to be in the correct order or
position number.
The Expert Menu for trunked systems have a few different options, such as “Narrow FM” in case your
system uses NFM on a band that is defaulted to regular FM, “Dwell” which controls how long the scanner
waits for activity, the “MultiSite” feature for networked trunked systems and the ability to set custom tables
and fleet maps as needed.
Trunked Systems can also be programmed with a “
Wildcard
”. This allows you to search the trunked system
and hear any traffic on the system even if the talkgroups are not programmed specifically. Otherwise you
would hear only traffic specified in your Scan Lists.
When programming
Search
events (SRCH) you can then select one of 3 options, Limit, Service and
Sweeper.
When you select
Limit Search
you enter the lower and upper limits of your desired search along with a
name (Tag). You can then enter more detailed specifications, such as the LED, Alarm and backlight
settings and Expert Menu items like the modulation type (if different than the default), attenuator, delays,
Zeromatic setting, hit count and the direction you want to search.
If you select
Service Search
you can choose the Service you want to search from the options presented
(such as Public Safety, CB, Railroad Aircraft etc.) as well as the LED, Alarm and backlight options and
other parameters.
For
Spectrum Sweeper
searches you can select to search all bands or just the Public Safety allocations. You
can also turn on and off specific band segments, called Sub Bands. The LED, Alarm and Backlight
parameters and other options work the same as with other searches.
If you want to store a Search Hit look for the “Stor” (
Store
) soft key when the radio stops. This will send
that hit’s information to memory as a separate Scannable Object that can then be assigned to any of the
Scan Lists in the radio.
While searching you can press the PSE (
Pause
) key to stop the search and stay on that channel until you
want to move on.
Special Programming Features
The GRE has several unique features that you can use to make programming easier once you learn how to
use them. One of these is the “
Dupe
” (“Duplicate”) option. This works like a Cut & Past operation on a
computer, you copy a channel, talkgroup etc. to a clipboard and paste it where needed. This is useful when
you have a lot of similar objects to program.
