Trunk Scanning
Trunk Scanning
The scanner tracks transmissions that use the
Motorola Type I, Type II, hybrid, EDACS, and LTR
analog trunking systems.
Simultaneous Trunking
The scanner allows you to track up to 20 systems
at a time. You can trunk scan or search and scan
conventional frequencies at the same time. You
can program conventional frequencies in the
same bank as trunking systems, but only one
trunking system per bank.
After the scanner is finished checking activity in
the trunked system, it scans other conventional
frequencies in the bank. (Only trunking
frequencies are programmed in Trunk Mode.)
If a system is inactive for 1 second and there are
no conventional channels in the bank, the scanner
starts scanning the next selected trunk bank. If
you turned DELAY on, the scanner starts scanning
the next trunk bank after about 2 seconds.
Setting Squelch for the Trunking Mode
For trunked reception, a good squelch setting is
in the center of the range with the white marker
pointing to the rear of the scanner. If it is set too
high, it could prevent your scanner from locking on
the control channel reliably. If it is set too low, it will
slightly delay finding the control channel. The best
setting is the same as for conventional reception
and is critical for monitoring trunked systems.
Trunk Operation
Programming Trunked Frequencies
Programming trunking frequencies is the same as
non-trunked frequencies, except that you must
store the appropriate mode (MO, ED, or LT) with
each frequency.
