You can also toggle this setting by pressing

Narrow FM:
Use
Yes
when the system is known to use Narrow FM modulation. Most 900 MHz analog trunked radio systems utilize NFM modulation.
Default is
No

AudioBoost:
When set to '
On
', sets a 6 dB boost for all activity on the system. Default is
Off
.
Press

Off
.
Dwell:
Sets the amount of time the scanner dwells on a Motorola, P25, or EDACS system control channel for activity on programmed talkgroups. Use
(default)
0
for automatic mode, which uses control channel information to determine when all current talkgroup information has been broadcast by the
system.
Enter the amount of time,
0-200
(0 - 20 seconds), for the delay. Default is
0
.
DIG AGC:
When set to '
On
', instantly compensates for low user audio levels that are common on digital systems. '
G
' (
On
) or '
g
' (
Off
) will appear in the
right
of the display when a channel is active to indicate AGC status. Default is
On
.
Note:
If you program a channel as NFM that is transmitting in FM mode,
the audio will sound too loud. Similarly, if you program a channel as FM that is transmitting in NFM mode, the audio will sound too quiet. Incorrectly
matching the modulation setting to the actual modulation used is the biggest reason for unbalanced audio between channels.

AutoMove HRs (LTR only):

Invert Data (EDACS Narrow only):
For some EDACS Narrow systems, the control channel data may need to be inverted if you can't receive (hear) the
control channel. Default is
No

Yes

No

Multi-Site
(Motorola/P25 only):
Used with Motorola Networked and P25 trunked radio systems. The multi-site feature mainly concerns how the scanner
"looks" at the control channels you have programmed into a particular system object. Default is
Off
. [
Press

to select:

- the scanner will find the first usable control channel in the control channel list and use it to track the system.
Roam
- while (you are) moving, the scanner will attempt to lock on the best site it can find. The scanner will always attempt to lock on to control
channels where the decoding quality is greater than 'Threshold Hi', and will search for new control channels when the decoding quality of a control
channel drops below 'Threshold Lo' (see next entries below). If no control channels are available that meet the Threshold Hi criteria, the scanner will
seek the best control channel to use, and continue checking periodically for a new control channel that meets the Threshold Hi criteria.
Stat
- intended to allow you to scan through
all
decent quality control channels while stationary (say, at home or work) so that you can hear all of the
available traffic on all of the available receivable decent quality control channels depending on the
Check All CC
setting below. [
Threshold Hi
(Motorola/P25 only):
When
Multi-Site
is set to
Roam
, sets the control channel decode % threshold for a site to be considered good when
looking for a new site.
Enter the percentage (
1-99
) and press
SEL
/
ENT
. Default setting is
95
(%).
Threshold Lo
(Motorola/P25 only):
When
Multi-Site
is set to
Roam
, sets the control channel decode % threshold for a site to be considered out of range,
which will begin the process of looking for a new site.
Enter the percentage (
1-99
) and press
SEL
/
ENT
. Default setting is
75
(%).
Check All CC
(Motorola/P25 only):
When
Multi-Site
is set to
Stat
(stationary) This setting determines how the scanner scans the control channels.

- the scanner will check a new control channel on each pass, starting with the next frequency in line after the previous pass. It will check only one
control channel per pass. [
The scanner will park on a different
decent
quality control channel each time it scans that system. [
On
- the scanner will park on each
decent
control channel in the list successively looking for programmed talk groups BEFORE leaving that system
and moving on to other system's or conventional channels. [
T Tables
(Motorola/P25 only):
Allows you to select the default trunking table or to customize the tables for each type of system. Trunking tables are
for implicit and VHF/UHF systems. The
software will also allow you to select the tables needed for each type of
system.
For Splinter Systems
(analog 800Mhz systems with frequencies between 866-869 MHz [or rebanded 851-854 MHz] ending with 0 instead of 5 e.g.
852.1250, not 852.1375) select
Splintr
.
For Motorola/P25 Systems
there are two types of systems: Explicit mode and Implicit mode channel assignment. Explicit mode systems include all
information needed to determine voice frequencies on the control channel. For
Explicit
mode systems, leave this setting at
Default
. The system will
automatically detect the band plan and populate the table for the system. You must supply the system's band plan for
Implicit
systems for the scanner to
correctly determine voice frequencies.
For Rebanded Motorola Systems
you must select
Custom
and create a custom band plan. For Motorola 800 MHz rebanded table entries see
.
For VHF and UHF Systems
Custom
will be the only option. You must program the applicable lo channel, hi channel, offset, base frequency, and step for
the system. I have found an explanation at the
Trunked Radio Systems User’s Page
that describes how to find some of this information. Look for
'Determining Base and Offset Frequencies for the BC245xlt'
