Saving Trunking Channels
Trunking channels are dened using the
same procedure for non-trunking channels.
In each bank, you can mix channel modes,
including conventional, but you can scan only
one trunking mode at a time, either EDACS,
Motorola, or LTR.
Because Motorola control frequencies
change daily, you should save all the control
frequencies in the same bank. If you do not
know the control frequency, save all the
Motorola frequencies in the same bank.
EDACS frequencies are assigned Logical
Channel Numbers (LCN) and organized in a
specic order. To scan correctly, you must
program the frequencies in LCN order, starting
with Memory 01.
Trunked modes (MO, ED, and LT) can only
be selected for frequencies above 137
MHz that use trunking operations.
For information about adding text tags to
a channel, see “Text Tags” on Page 44.
Trunk Scanning
In each bank, you can mix conventional
channels and frequencies in a bank. However,
you can scan only one trunking mode at a time,
either EDACS, Motorola, or LTR.
To focus on trunk scanning, during a normal
scan, you turn off banks that contain only
conventional channels.
For Motorola channels, your scanner displays
the Talk Group ID memory location, received
frequency, voice channel (VC), and the Motorola
ID number.
To change the scanning direction, press  or
.
Your scanner automatically mutes the
audio while it decodes control channel
data. However, we recommend you turn
SQ clockwise and leave it set to a point
just after the hiss stops. This lets the
scanner quickly acquire the data channel.
For Motorola trunking systems, more
than one talk group can transmit at a
time. If you manually tune the scanner,
you will hear the talk group on that
channel, but the display will alternate
between all active Talk Group IDs.
