Atten On or Off
When on, applies 20 dB of attenuation
to all transmissions on this TSYS. Use-
ful in areas where interference from
nearby strong signals is present.
Narrow FM Yes or No
Use Yes when the system is known to
use Narrow FM modulation. Most 900
MHz analog trunked radio systems uti-
lize NFM modulation.
AudioBoost On or Off
Activates 6 dB audio level boost for all
activity on this TSYS
Dwell 0-200 x 100 mS
Sets the amount of time the scan-
ner dwells on a Motorola, or EDACS
system control channel for activity on
programmed talkgroups. Use 0 for
automatic mode, which uses control
channel information to determine
when all current talkgroup information
has been broadcast by the system.
Multi-Site
Off, Roam or Stat
(Stationary)
Used with networked Motorola trunked
radio systems. When
M u l t i -
Site=Off
, the scanner will find
the first usable control channel in
the control channel list and use it to
track the system. When
M u l t i -
S i t e = R O A M
, 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 chan-
nel drops below Threshold Lo, and,
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.
When
Multi-Site=STAT
, the
scanner will track the system using
every usable control channel in the
control channel list.
