from the coverage of one site, their radio will search other control channel
frequencies for a better site to use.
Your PSR-410 includes a Multi-site feature that can enhance the operation of
the scanner when monitoring Multi-site systems. Multi-site can be enabled
by editing the trunking system (TSYS) parameters for a Motorola system.
Multi-site can be set to Off, Stat (Stationary) or Roam. By default, Multi-site
is set to OFF.
The Roam setting is ideal for those times when you are driving around in
the service area of a networked trunked radio system, as it allows the radio
to find and use the best tower sites as you move in and out of the coverage
footprints of different sites. The Stat(ionary) setting is ideal for those times
when you are not moving and are within range of more than one tower site,
as it will allow you to monitor traffic from any tower that you are within range
of.
To activate Multi-site mode on a Motorola system, follow these steps:
Press PROG, then navigate to a talkgroup on the networked multi-site
system using the 3456 keys.
Press the EDIT softkey, then press the CURR softkey.
Scroll down to the TSYS item and press the SEL key to edit the TSYS
parameters.
Scroll to Multi-Site . Use the 34 keys to select Off,
Stat
or Roam . When set to Off , the scanner will find the first usable control
channel in the control channel list and use it until it is no longer usable.
When set to Stat (ionary), the scanner will track the system using any
control channel in the list that is usable. When set to Roam , the scanner
will attempt to locate and use the best possible control channel and ignore
others, until the control channel is no longer usable, then it will locate a
new "best control channel" to use. When Multi-Site=ROAM , the
scanner will always attempt to lock on to control channels where the
decoding quality is greater than the Threshold Hi setting, and will search
for new control channels when the decoding quality of a control channel
drops below Threshold Lo setting, and, if no new 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. When Multisite=STAT is
selected, the Check All CC TSYS parameter controls whether the scanner
