Understanding Your Scanners Modes
21 However, you cannot program
MOT (Motorola), or ED (EDACS)
mode in VHF. Each receive mode
affects how your scanner operates
when scanning and receiving
transmissions, and also affects
what transmissions you receive
when you set the scanner to the
closed mode. See “Changing the
Receive Mode” on Page 49.

AM MODE
The AM mode sets the scanner to
receive transmissions using
amplitude modulation (AM),
primarily used for aircraft, military,
some amateur radio, and some...

22Motorola systems are trunking
systems used primarily by
business and public safety groups
to efficiently allocate a small
number of frequencies (as few as
five) to many groups of users (as
many as several thousand). To do
this, each group of users in the
system is assigned to a specific
talk group. For example, the east
side patrol officers might all be
assigned to talk group 2160. One
channel in the system is
continuously transmitting data that
identifies which talk...

SS=Subfleet ID
Type I systems are usually
organized with different user
groups assigned to different fleets.
Ô
To properly map the raw Type I
data to the correct fleet-subfleet
format, you must program the
correct fleet map into the scanner.
Fleet map information is widely
available on the Internet for most
Type I systems in use.
Type II system talk groups are
identified by a 5-digit number.
Valid talk group IDs are divisible
by 16. If you try to enter an...

Number (LCN). For the scanner to
correctly switch to an active
frequency, you must program the
frequencies in LCN order, starting
with
Memory 01. EDACS talk group
IDs are entered as a 4-digit
decimal number from 0001 to
2047 or AFS (Agency Fleet
Subfleet) number from 00-001 to
15-157.
When there is activity on an
EDACS system, that information is
sent out on the control channel.
The scanner decodes the ID for
the active talk group. In the...

You can set your scanner to
change the way it receives
signals. These settings, called
open mode and closed mode,
affect how the scanner receives
signals from communications
systems that use some type of
closed squelch (such as Motorola
and EDACS systems).
