SETTING SQUELCH FOR THE
TRUNK TRACKING MODE
Your scanner’s squelch setting is automatically adjusted
in the trunking mode, which means it is not necessary to
manually adjust squelch while tracking trunked transmis-
sions. However, the squelch setting can affect how fast
your scanner acquires the data channel, and, in some in-
stances, can prevent your scanner from acquiring the
data channel at all.
We recommend you set
SQUELCH
to this position before
selecting a trunked bank.
Note:
You can change this setting, if necessary, to pro-
vide better performance in your area.
PROGRAMMING TRUNKED
FREQUENCIES
Before you program your scanner to track a trunked sys-
tem, consider the following:
• Valid trunked system frequencies range from
851.0125–868.9875 in 12.5 kHz steps.
• You can use any of your scanner’s banks as either a
trunk tracking bank or conventional scanning bank,
but you cannot mix the two.
• The scanner only scans one trunked system at a
time. Although you can store frequencies for more
than one trunked system in one of your scanner’s
banks, the scanner only scans the frequencies
associated with the first data channel it finds.
Before scanning a trunked system’s transmissions, you
must store the trunked system’s frequencies in one of
the banks in your scanner by following these steps.
