CHAPTER 1—Welcome to the OpenSky Network
OpenSky Overview
M/A-COM’s OpenSky is a suite of radio communications products implementing an integrated digital
voice and data system based on the Internet Protocol.
The OpenSky network is digital, but provides interoperability with analog radios, making it possible to
integrate existing (legacy) equipment alongside the
most sophisticated digital equipment available today.
If you’ve been issued an M-803 to replace a
conventional analog voice-only radio, you’ll
particularly appreciate the integrated voice and data
capabilities of the all-digital OpenSky mobile
equipment.
Even experienced digital subscribers recognize and
value the addressability precision and expanded
coverage strength of the end-to-end TCP/IP OpenSky
Intranet.
Internet Protocol (IP) Network
OpenSky’s Wireless Private Network is changing the
nature of real-time communications for large fleet
mobile businesses and public safety organizations
alike.
TCP / IP Backbone
Using Internet Protocol (IP) as a network backbone for
end-to-end user applications, OpenSky integrates
digital voice and packet data transmission over a single
network that provides significant performance
advantages over yesterday’s uneasy alliances of
independently-built radio networks trying
unsuccessfully to interact.
•
M-803 Operator Manual
Like tuning into a channel in a conventional FM
radio system, logging onto the OpenSky network
with your pre-configured user profile will place
you in contact with the members of a software-
Software Version OTP 5.07
Welcome to the OpenSky Network—CHAPTER 1
defined talk group consisting of the set of users
you need to talk with most.
•
Unlike your conventional FM radio, your M-803
mobile radio is a node on an Internet-Protocol (IP)
network with its own unique IP address.
Addressable Headers
Messages intended for you (whether voice or data) are
broken into packets with identifying headers, just like
World Wide Web internet communications, and
targeted to your specific IP address.
Like cell-phone calls,
messages are delivered
directly to your
equipment.
But, like radio calls, users
select which calls to
receive by “tuning in” or
“locking out” other user
groups.
You can travel anywhere within your network, even a
hundred miles or more from the sender, and messages
intended for your IP address will find their way across
the network, handed off from base station to base
station, until they are re-configured and delivered to
your personal receiving set.
This doesn’t mean your communications are traveling
across the World Wide Web. Far from it. OpenSky is a
private wireless Intranet that adopts the best features of
IP protocol for increased communications efficiency
and capacity.
System-Wide Voice Encryptability
Furthermore, your communications are packeted as
they travel the network, so they can only be deciphered
by networked equipment. Your sensitive conversations
and data transfers can even be encrypted end-to-end for
enhanced system-wide security.
Integrated Voice and Data
Your M-803 Gemini Series Mobile Radio is a
hardware component of the OpenSky network, an
integrated voice and data communications system that
delivers end-to-end digital voice and data transmissions
over a single wireless network to your dash-mounted or
trunk-mounted device.
Software Version OTP 5.07
M-803 Operator Manual
CHAPTER 1—Welcome to the OpenSky Network
Digitized Voice, Text and Graphics
By converting analog voice waves to digital code
before transmitting them over the network, OpenSky
technology makes it possible for mobile radio users to
send and receive voice transmissions at the same time
they receive and view data (via the radio’s serial port)
on an optional equipment Mobile Data Terminal.
For graphics, interface a
Mobile Data Terminal
(MDT) through your
radio’s RS-232 peripheral
port.
With an M-803 in your vehicle, you’ll be able to scroll
through complex instructions, driving directions, or
emergency warnings on an optional mobile computer
or terminal device while at the same time carrying on
conversations with dispatchers or other mobile
operators in your coverage area.
OpenSky and the M-803 eliminate the need to run
separate systems for voice communication and data
transmission. And, with OpenSky, you won’t even
have to switch between radio modes to do both
simultaneously.
RS-232 Interface
For data transfers or graphics, your M-803 is
constructed with an industry-standard RS-232 interface
serial port for connecting an optional equipment
Mobile Data Terminal (MDT), laptop PC or third-party
display or key-entry device.
OpenSky works seamlessly with equipment from
popular manufacturers and off-the-shelf applications
through a standard UDP/IP protocol, providing you
with simple “plug and play” connectivity.
Suddenly and simply, the same M-803 you’ve been
using for voice conversation and tuning radio
frequencies becomes the device you use to view
photographs, maps or driving directions, generate
reports, access databases, in short to share any digital
file your job requires.
M-803 Operator Manual
Software Version OTP 5.07
Welcome to the OpenSky Network—CHAPTER 1
Multi-Agency Coverage
OpenSky is scalable and designed to accommodate a
virtually unlimited number of mobile and portable
devices from a single fleet, or even a complex network
made up of several cooperating agencies.
Examples of how OpenSky improves cooperation:
•
Every truck in the FedEx fleet can share one large
national network.
•
Every cruiser in a state-wide police agency can
communicate with any other cruiser, from one end
of the state to the other.
•
Patrolmen with older analog equipment can
connect seamlessly with newer digital devices over
the same network.
•
Emergency response agencies share the same
network for improved communications during a
massive crisis.
•
With an M-803 at the heart of your trunk-mounted
VTac Vehicular Tactical Network, your vehicle
provides off-network user-to-user communications
at the scene of an emergency.
Promotes Interagency Cooperation
See full discussions of
Talk Group, User Group
and User Profile elsewhere in this manual.
In fact, the system is best suited to multi-agency public
safety networks over areas as large as an entire state:
every cruiser, ambulance and fire truck and all their
dispatchers and support personnel sharing voice, data,
even graphics over the same network.
Talk to Anyone on the Network
Each user needs only one radio to connect seamlessly
to many independent agencies or cooperating dispatch
networks.
•
Software Version OTP 5.07
There’s no need to monitor multiple frequencies on
several pieces of equipment to maintain contact.
M-803 Operator Manual
CHAPTER 1—Welcome to the OpenSky Network
•
User talk groups connect you at all times with
precisely the users you need to reach, no matter
who they work for, or where they’re located within
the network.
Connectivity with Legacy Equipment
The all-digital, end-to-end TCP/IP OpenSky Intranet
even provides support for legacy equipment and
protocols both digital and analog.
Along with supplying voice and data to your M-803
mobile radio, the network will also support existing (or
“legacy”) radio equipment you may still need to use
during a hardware rollover.
This also means you’ll be able to make radio contact
with cooperating agencies on the same network,
whether or not they have made the conversion to
OpenSky equipment, as long as they use their radios to
network with OpenSky.
Voice and Data to a Single Device
For graphics, you’ll need
to remain connected to
your Mobile Data
Terminal (MDT).
With OpenSky, you won’t need independent system
architecture to receive voice and data communications.
And, with a Mobile Data Terminal connected through
the peripheral interface, you’ll have unprecedented
ability to send and receive forms, NCIC profiles, maps,
floorplans, all the complicated graphical data you need
to make informed on-the-job decisions.
Improved Coverage and Signal Strength
Part of OpenSky’s scalability is its ability to accommodate as many base stations as your coverage area
requires for robust voice and data transmissions,
wherever your route may extend within the network.
Vehicular Tactical Network
VTac devices (trunk-mounted M-803 radios arrayed
with a duplexer and a vehicular repeater) and OpenSky
cell sites automatically extend coverage into otherwise
hard-to-reach areas.
M-803 Operator Manual
Software Version OTP 5.07
Welcome to the OpenSky Network—CHAPTER 1
With a VTac device in your vehicle, you’ll enjoy
extended signal reach into buildings or behind barriers,
as well as repeater capability for off-network unit-tounit communications.
Background Roaming and Switching
Automated switching takes place in the background
with OpenSky, so you’ll no longer be required to scan
for an open channel, or wait for an available channel,
when you move through your coverage area.
Signal strength sensitivity
is user-modifiable to
reflect local conditions.
Instead of depending on choices from a central
switching station, your radio itself constantly monitors
signal strength and makes its own decision to roam to
another base site for a more robust connection.
Chances are you’ll never know your unit has been
“handed off” to a new base station and automatically
assigned to the best available channel.
Better Peak-Time Performance
OpenSky’s digital trunking architecture provides
enormous advantages over conventional FM operation.
Conversation capacity is effectively doubled by the
system’s ability to carry two voice-to-voice conversations over the same channel that was previously
dedicated to just one.
TDMA Technology
The M-803 uses TDMA technology to allow multiple
users to share a single RF channel. In addition, a single
25kHz RF channel can support simultaneous digital
voice and data communications.
By doubling the capacity of each channel, the OpenSky
TDMA network relieves the pressure of heavy use
without additional channels.
The M-803 supports multiple voice groups, multi-level
priorities, priority scanning, dynamic voice group
assignment, pre-emptive emergency calls and optional
encryption.
Software Version OTP 5.07
M-803 Operator Manual
CHAPTER 1—Welcome to the OpenSky Network
Optional GPS Tracking
GPS tracking uses a
small fraction of
system resources,
but eliminates verbal
location reporting for
huge overall
capability gains.
GPS tracking devices embedded in optionally-equipped
M-803 radios quickly and accurately locate users on a
visual display screen for dispatchers, virtually
eliminating the need for users to report their position.
With an overview of the locations of all vehicles,
dispatchers have the information they need to assign
the nearest vehicle to a developing emergency.
By eliminating the background chatter of constant
location reporting, OpenSky frees up system resources
for more critical communications, especially at peak
traffic times.
Software-Configured Device
Your M-803 is a “soft” radio. Its functions are determined by OpenSky software applications, in much the
same way computer hardware is configured for
different applications.
Unlike older analog radios you may have used, with
their hardware-based proprietary functions, your
M-803 converts voice waves into digital information
before it transmits to the network, providing noise-free
audio transmission and reception.
Make any radio in the
system “your radio” by
logging on with your
identity code.
What’s more, because each user in the network has a
unique identity code, you can activate your identity
from any radio connected to the network. Any radio
from your agency’s hardware stockpile can become
“your” radio and log on with your profile.
Multi-Mode Functionality
Finally, if you need to be multi-mode, your M-803
supports several (even several applications simultaneously) providing capability with the needs of
different user groups.
You can operate under the OpenSky digital protocol or
use the same device to access Conventional FM with
CTCSS analog FM or APCO Project 25 Phase 1
operations, depending on the user configuration of your
network or agency.
M-803 Operator Manual
Software Version OTP 5.07
Welcome to the OpenSky Network—CHAPTER 1
Analog-to-Digital Rollover
The M-803 can work with existing analog infrastructure to enable an essentially seamless transition to
fully digital communications
If your user group or another user group with whom
you communicate is making the transition from analog
to digital service over time, you’ll be able to use your
M-803 throughout the rollover by selecting the correct
mode.
What’s more, the M-803 is field re-programmable over
the radio channel to allow for future capabilities
without replacing the existing subscriber equipment.
•
The principle operating mode currently in use is
the OpenSky Trunked Protocol (OTP).
•
From the Mode Selection Menu, you can also
access OpenSky Conventional FM (OCF) with
Continuous Tone Coded Squelch System
(CTCSS).
•
From the Mode Selection Menu, you can also
access OpenSky Conventional (OCF) mode using
APCO Project 25 Common Air Interface.
Software Upgradeable
As with computer hardware, your mobile radio
equipment is upgradeable each time the OpenSky
software enables a new feature or operational
enhancement.
Communications protocols, radio features, and
protocols can be changed easily and transparently to
the user, during a shift or during “sign-on” at the
beginning of a new shift.
Enhanced Digital Features
See full discussions of
Talk Group, User
Group and profiles in
Chapter 2 of this
manual.
The all-digital network and OpenSky’s digital trunking
features also enable a rich array of network enhancements unthinkable over historical FM broadcast
systems.
Software Version OTP 5.07
M-803 Operator Manual
CHAPTER 1—Welcome to the OpenSky Network
Voice grouping (into talk groups, user groups, and
profiles) is probably the most obvious advantage to
individual users, but the interconnectivity of the
OpenSky network also enables a variety of essential
enhancements including:
•
Priority scanning
•
Multiple priority levels
•
Pre-emptive emergency calls
•
Selective calls directly to User ID
•
Late-entry calls
•
Autonomous roaming for wide area applications.
You’ll benefit from high-quality, noise-free voice
communications with enhanced speech clarity
compared to analog, especially in noisy environments.

CHAPTER 2—Network Organization
Your Voice Feature Personality
When you activate your radio at the beginning of a
shift and sign on with your unique identity code, your
radio is assigned its IP address and “provisioned” with
a radio personality that identifies the other users on the
network with whom you are most likely to need to
communicate.
Some users you’ll only monitor, others you’ll want to
talk with during the course of your shift, just as with
older analog equipment you talked over one frequency
and monitored others to keep informed about the
activities of users in your agency, workgroup, task
force, fleet or geographic area.
Profiles are assigned by
your network administrator to match your
communication needs.
You’ll have access only
to those users who fall
within your profile.
Your overall radio personality is organized into User
Groups (talk groups and listen groups), similar to a
channel in a conventional FM radio system. These user
groups are then organized into Profiles (collections of
up to 16 user groups), similar to banks of channels.
Finally, as many as 16 profiles make up your radio
Personality.
Only one profile is active at any time. Within that
profile, only one user group is your Talk Group; the
others are Listen Groups. So, while you have
tremendous capability to establish contact with a very
large number of users, you’ll need to select the profile
that puts you into voice contact with the talk group you
need at any time.

M-803 Operator Manual
Software Version OTP 5.07
Network Organization—CHAPTER 2
User Groups
A user group is a set of users who regularly need to
communicate (all the officers in a state police barracks,
for instance, or all the drivers who work a particular
shift).
•
In conventional FM radio broadcast systems,
these users work together by tuning to the same
channel.
•
In the IP-backbone OpenSky digital network,
subscribers in a user group are connected by a bit
of data in the header of every voice or data packet
addressed to the members of the group.
With OpenSky, members of the same user group can
stay in contact regardless of where they roam within
the network, whether the network incorporates a single
county, a state, even the entire nation.
Network capacity is the
only limitation on the
number of users that can
make up a group.
Dispatchers maintain contact with all members of the
group, and each user can stay in “push-to-talk” contact
with the dispatcher and all the users in their talk group,
even if those users are from different, inter-networked
agencies.
The Figure below illustrates a small user group of four
M-803 mobile radios.
Figure 1 User Group
Sample Configuration
Each radio assigned
to an individual user
Nothing about this user group so far defines it as a Talk
Group or a Listen Group. That determination is made
when user groups are gathered together by the network
administrator into the larger groups called profiles.
Software Version OTP 5.07
M-803 Operator Manual

CHAPTER 2—Network Organization
Profiles
A profile is a set of up to 16 user groups. All sorts of
configurations are possible within this simple
architecture. Police officers on the same shift might
make up a profile, for instance. Within this profile,
each police station on the network might be assigned a
user group. So the profile would connect all the
cruisers from 16 stations for an entire shift.
Officers from each station would most likely be in
“push-to-talk” contact with one another; all other
officers on the same shift would most likely monitor
the other groups for “listen-only” access to all other
calls within the profile. But this is only one possible
configuration.
Members of a talk group
are not necessarily
scanning the calls of the
same listen groups.
Of the 16 available
profiles, Network
Administrators will often
reserve one for Dynamic
Regroup use.
14
A user group might just as easily include officers from
several stations: a SWAT team, for example, or a
special emergency task force might require the
collaboration of special personnel or equipment from
different police stations, or even other agencies.

In conventional FM radio broadcast systems,
users with this sort of relationship would create an
“ad hoc” profile by tuning to one channel for talkgroup privileges and scanning an entire bank of
channels to monitor the conversations of other
groups.
•
In the IP-backbone OpenSky digital network,
members of the same talk group automatically
receive every voice message addressed to the
group, and monitor the voice messages of every
other user group in the profile.
Each user in the OpenSky network can be assigned as
many as 16 profiles by the network administrator. At
any time during a network session, users can select the
profile that suits their needs by using the front control
keypad to access the Profile Menu. If selected for
Dwell Display, the Current Profile selection will be
visible in the radio’s front panel display area.

Talk Groups
While your active profile can contain up to 16 user
groups, only the primary group in any profile is your
Talk Group. All the other user groups in your profile
are listen-only groups. You’ll hear the calls from these
groups but they will not hear your voice unless your
user group is part of their profile.
To initiate voice-to-voice contact with a particular user,
you’ll have to select the profile that makes that user
part of your talk group. This is only possible if your
network administrator has configured a talk group that
contains both you and the other user.
If each of you has a profile that includes the other in a
talk group, you can each select the profile that puts you
into “push-to-talk” contact with the other. (Or one of
you can reply to the other in Talkback Mode.)
Listen Groups
All the other user groups in each of your up to 16
profiles are “listen groups”. See the User Profile
Figure above for an illustration of how user groups are
related in a profile.
By adding different listen groups to your several
profiles, your network administrator can change the
configuration of the user groups you can monitor at any
time by making the appropriate choice from the Profile
menu.

CHAPTER 2—Network Organization
You may only have one talk group, but that doesn’t
keep you from tuning in different profiles to monitor a
different “bank of channels.”
Talkback Scanning
While you cannot initiate contact with users in your
“listen groups,” you can reply to their incoming calls
using Talkback Scan mode.
With your radio in Talkback Mode, your display screen
will show the identity of your most recent incoming
caller. Press the Push-to-Talk button on your handset
and send your voice reply.
Radio Personality
Your radio personality is a collection of up to 16
profiles. The entire personality is organized by your
network administrator and is unique to your
communication needs.
If an emergency prompts
your Network
Administrator to enact a
Dynamic Regrouping of
user groups, you’ll be
prompted to conduct a
mid-shift log-on to reprovision your radio with
an updated personality that
includes a preprogrammed or ad hoc
emergency user profile.
16
When you activate your radio at the beginning of a
shift and sign on with your unique identity code, your
radio is assigned its IP address and “provisioned” with
a radio personality that identifies the other users on the
network with whom you are most likely to need to
communicate by voice.
Your overall radio personality is organized into User
Groups (talk groups and listen groups), similar to a
channel in a conventional FM radio system. These user
groups are then organized into Profiles (collections of
up to 16 user groups), similar to banks of channels.
Finally, as many as 16 profiles make up your
personality.

Radio personality architecture gives you tremendous
flexibility to organize your communications needs,
even as conditions change. Network administrators can
even create ad hoc work groups and profiles to respond
to emergent conditions, then prompt the affected users
to re-provision their equipment while the emergency
unfolds.
With 16 profiles you can participate in as many as 16
talk groups. Or, if you only need one talk group, you
can still have up to 16 different profiles that can add
more than 200 other user groups to your listen group
pool, each with an almost unlimited number of
subscribers.
Of course, with potentially hundreds of voice calls in
your profile at any time, you’ll appreciate the ability to
establish Priority Scan groups, or even Lock Out others
to help focus your incoming calls.

CHAPTER 3—Controls and Indicators
Before Your First Shift
Don’t read this manual
cover-to-cover.
Most information in this
manual is repeated in
several places.
You’ll probably learn most
of what you need to know
by browsing sections that
interest you most.
If you’re already familiar with mobile radio functions
and the “profile and personality” architecture of an alldigital network, you’ll find the features and controls of
your new M-803 to be logically arranged and easy to
understand.
But if you’re new to cellular radio service, and
especially if you’re migrating to OpenSky from an
analog radio environment, take some time to review the
Network Organization chapter of this manual before
operating your radio.
In either situation you’ll want to completely familiarize
yourself with the controls and indicators of your new
radio before you start trying to use it on the job. In
particular, you’ll want to be able to scroll your way
through menu display choices and quickly select the
appropriate radio profile for the changing conditions of
your work day.
Radio Controls
Examine your radio thoroughly and familiarize
yourself with the location and operation of its controls
and indicators before studying their functions. Except
for the rear-panel peripheral interface, all the
operational controls for the M-803 are located on the
control panel or handset.
Whether your passenger compartment is equipped with
a dash-mount Mobile Radio Unit (MRU) or a
subsidiary Control Head Unit (CHU), the following
section will introduce you to all the controls and
indicators of your radio’s front panel.
20

Controls and Indicators—CHAPTER 3
Front Panel Components
The front panel of your M-803 (or CH-103) includes
the Power Button/Speaker Volume Dial, the Microphone/Speaker I/O Port, a 5-key “soft-button” keypad
for making menu selections, a 19-character vacuum
fluorescent Display Panel, 3 Mode Selector buttons, an
Emergency Button and an Ambient Light sensor.
Up to five Control Head
Units (CHU) can be
supported by a single
Mobile Radio Unit (MRU).
The most typical multiple
CHU configuration would
be a large fire truck or
other vehicle with a dashor trunk-mounted M-803
and auxiliary control heads
positioned elsewhere on
the vehicle.
Your Push-to-Talk button is located on your hand-held
detachable microphone or hands-free speaker box (not
shown here).
Because an M-803 mobile radio can support as many
as five Control Heads, your installation may or may
not include the hardware “box” behind the front panel.
The figure below shows the complete dash-mounted
configuration of an M-803 mobile radio complete with
front control panel.
Peripheral equipment such as a mobile computer or
data terminal connect to the M-803 through the rearpanel peripheral interface.

Peripheral Interface
The M-803 supports a variety of interfaces with its
flexible interconnect. The rear panel provides power
supply connectors and interfaces for both analog and
digital peripherals.
RS-232 Port
The serial RS-232 port operates in asynchronous
ASCII mode for configuration and control and switches
to Serial Line Internet Protocol (SLIP) mode for data
communication between the fixed network and a
mobile computer or terminal device.
I/O Connector
The I/O connector provides interfaces for an external
10 Watt speaker.
CAN 2.0 Bus
The rear panel also provides access to an industry
standard Control Area Network (CAN) 2.0 Bus for
reconfigurability and peripheral support.
Through the CAN port the M-803 in either dash- or
trunk-mounted installations can connect to as many as
5 Control Head Units (CH-103) or other CAN
peripherals such as public address. A terminator is used
if no CAN devices are used. The maximum length of
the CAN bus is 40 meters.
Hardware Connections
While day-to-day operations are conducted from the
front panel controls, the rear panel connectors will be
useful during installation, troubleshooting and
hardware upgrades.

Talkgroup. The bottom line shows the user’s
choice of the current Profile, Channel, Caller or
Received Talkgroup.
Users who fail to select a
dwell display will not
track channels, calls, or

Display Panel Functions—CHAPTER 4
operate your radio as a fully-networked component of
the OpenSky digital network and carry on rich-featured
communications with similarly networked agencies or
subscribers.
At startup, your M-803 automatically selects the
OpenSky Trunked Protocol (OTP) to provide the full
range of features available on your digital voice and
data network.
Your only indication
that you have logged
on to the network is
the name of your
Talkgroup in the Dwell
Display.
On the other hand, if your agency cooperates with
several others in a multi-agency network supported by
OpenSky’s IP backbone, all agencies benefit from the
advantages of the network architecture whether or not
they’ve migrated from older analog equipment to
digital OpenSky radios.
For those occasions when you need to communicate
with radios using older protocols (such as conventional
FM), you can manually change your radio’s operating
mode.
Universal Connectivity
When conditions require it, you can re-configure your
M-803, with a simple menu selection, to access
conventional CTCSS analog FM or APCO Project 25
CAI operations. This is especially helpful when you
need to communicate with users from other agencies or
fleets not completely integrated with OpenSky.
•
The principle operating mode currently in use is
the OpenSky Trunked Protocol (OTP). Choose
OTP for full-featured communications with other
digital equipment connected to the OpenSky
network.
•
From the Mode Selection Menu, you can also
access OpenSky Conventional FM (OCF) with
Continuous Tone Coded Squelch System
(CTCSS).

When your Network Administrator initiates a midshift Personality Upgrade or Dynamic Regrouping,
you’ll engage the Over-the-Air Download mode.

If you stray outside the network’s strong coverage
area and require an off-network conventional radio
connection, select Coverage mode to temporarily
improve your capabilities.
To protect against inadvertent or too-hasty mode
changes, the M-803 software will force a confirmation
sequence before accepting your new selection.
Ø How to set your Operational Mode
1.) Use the Up and Down buttons to cycle through
the menu choices until Mode Menu appears.
2.) Use the Left and Right buttons to cycle through
the Mode Menu options: Trunked, Conventional,

radio personality composed of as many as 16 profiles,
one of which your network administrator has
designated as your Active Profile by default.
Your default profile will contain your most common
talk group and as many as 16 other user groups the
radio treats as “listen groups.”
Software Version OTP 5.07
M-803 Operator Manual

CHAPTER 4—Display Panel Functions
Each of your other profiles, if any, is another group of
as many as 16 more user groups, one of which is
always the default Talkgroup. See the Getting Started
chapter for a full discussion of user groups, profiles,
listen groups, talkgroups and radio personality.
It’s a good idea to
know the default
Talkgroup for each
Profile in your
Personality so you can
access it easily from
the Profile Menu.
If you need access to groups not part of your active
profile, you can use the Menu Selector Buttons to
access the Profile menu and switch to any other pre-set
menu that is part of your radio personality.
You’ll have to be familiar enough with your profiles to
know which user groups are organized under each
name. Or, if just want to access a new talkgroup, you
can tune in the profile for which the talkgroup you
want to access is the default.
Check or Change Active Profile Status
If your Dwell Display is set to Profile, your screen will
display your active profile at all times. Otherwise, to
see your current selection, use the Menu Selector
keypad to access the Profile Menu.
To switch to a new active Profile during your work
shift, access the Profile Menu from the Menu Selector
keypad and make a new selection from the options.
Ø How to set your Active Profile
1.) Use the Up and Down buttons to cycle through
the Menu choices until ProfileMenu appears.
2.) Use the Left and Right buttons to cycle through
the Profile Menu options established by your
Network Administrator.
3.) Press the Select button to lock in your choice.
Your selected Dwell Display will appear as soon as the
M-803 accepts your choice.

Prioritizing a Talkgroup
Priority Scan is
different from
Talkgroup status.
Even if you give a
user group Priority
Scan status, your
Talkgroup is still your
Talkgroup.
At different times during your shift you may want to
improve your radio’s sensitivity to incoming calls from
a particular user group. If you make no such changes
during a radio use session, the Default Talkgroup for
each profile will maintain automatic scanning priority
over all other user groups in the profile.
Increasing the scanning priority of a group other than
the Default Talkgroup improves your receptiveness to
that group’s calls compared to all the other groups in
your active profile, including the Default Talkgroup.
You may use the procedure below to establish one new
priority scanning group for every profile in your radio
personality. There’s no ranking order in scanning
priority: one group per profile is the priority group; all
other groups in the same profile are “non-priority.”
Ø How to Assign Priority to a
Talkgroup
1.) Use the Up and Down buttons to cycle through
the Menu choices until PriTGMenu appears.
2.) Your display screen shows PriTGMenu in the
bottom line and the current Priority Scan group in
the top line.
3.) Use the Left and Right buttons to cycle through
the list of user groups in your selected Profile,
until the group you want to assign Priority
Talkgroup status appears onscreen.
4.) Press the Select button to lock in your choice.
Your selected Dwell Display will appear as soon as the

Duration of Priority Assignments
If you make no priority assignments during your shift,
each profile selects the Default Talkgroup as the
priority scan group. When you use the Priority Scan
menu to assign scanning priority to a new group, your
assignment stays in effect until you change it or turn
your radio off. Powering Off erases all scanning
priority assignments and resets your radio to the
defaults.
Lock Out Talkgroup
There are at least two ways to focus your voice
communications by suppressing calls from user groups
in your active profile.
•
44
No Scan. By changing your Scanning Mode to
NOSCAN you can block all non-emergency voice
calls from the “listen groups” in your profile,
M-803 Operator Manual
Software Version OTP 5.07
Display Panel Functions—CHAPTER 4
concentrating your attention entirely on your
Default, Selected or Priority Talkgroup.
•
Lock Out. By locking out selected Talkgroups,
you can eliminate just the background “noise” you
select, focusing your scanning resources on just the
groups whose calls you wish to track.
Emergency calls will cut through your lock-out
command, but you won’t be distracted by the other
voice call activity from user groups you’ve locked out,
until you elect to run the menu again and remove the
lock.
Groups You Can Lock Out
•
Active Profile. It stands to reason that only groups
in your active profile can be locked out, since
they’re the only groups whose voice calls you’ll
hear. The Lockout menu responds to incoming
voice call activity, loading the names of calling
groups into the menu as the calls are received.
•
Received Call Menu. If you don’t find a name
you’re looking for in the Lockout menu, either it’s
not in your active profile, or you haven’t received
a call from that group yet in this radio session.
Until you do take a call from that group, you can’t
lock them out.
To protect against inadvertent or too-hasty Lockout
procedures, the M-803 software will force a
confirmation sequence before accepting your new
selection.
Ø How to Lock Out a Listen Group
1.) Use the Up and Down buttons to cycle through
the Menu choices until LockOutMenu appears.
2.) Your display screen shows LockOutMenu in the
bottom line and, in the top line, the name of a user
group from your active profile you’ve received a
voice call from since Powering Up.

3.) If the word NONE appears in the top line, you
haven’t received any voice calls from user groups
in this profile, so Lock Out is not an option.
4.) Use the Left and Right buttons to cycle through
the list of candidates, if any, until the user group
you want to Lock Out appears onscreen.
5.) Press the Select button to activate the fail-safe
Confirmation process.
6.) Use the Left or Right button to cycle through the

bottom line and, in the top line, the name of a user
group from your active profile you’ve received a

Caution Regarding Profile Changes
Talkgroup Lockout status does not survive a change of
Profile. If you need to select a new Profile after taking
the time to Lockout several talkgroups from your
current profile, understand that making the change will
Unlock all groups.
Compare your options before changing your profile. If
you can achieve your goal by temporarily assigning
Priority Talkgroup status to a user group, you may be
able to avoid having to lock out the same groups twice.
Select Scan Mode
Three scanning modes are available for the M-803, but
only one can be active at any time. Changing your
scanning mode changes the way your radio scans voice
calls for all of the profiles in your radio personality, no
matter which profile is or becomes active.
Your choice of scanning mode will broaden or narrow
the span of your communications with all the listen
groups in your profiles, but does not affect your
interaction with your talk groups.
Your scanning mode choice will stay in effect until you
change it again; even if you turn off your radio, your
current selection will be saved until your next use.

Enable/Disable Side Tones
Your radio sounds confirming tones when you press
the Menu or Selector buttons. Most users find this
audible confirmation helpful in navigating the menus in
the Display Panel.
Turning off your radio
does not affect your Side
Tone setting, which will
be saved for your next
use.
You can disable the side tones, if you wish, by
navigating to the Side Tone menu, and selecting Off.
To re-enable the tones, you’ll need to navigate back to
the same menu (without the benefit of side tones) and
this time select On.
For covert operations, it is important to be able to turn
off the audible side tones that occur when you press a
Menu or Selector button. For safety’s sake, though, you
probably won’t want to shut your radio down for the
time you’re planning to go covert.
To temporarily disable the tones that could expose your
presence and position, use the Menu Selector buttons to
access the Side Tone Menu. There are only two choices
in the Side Tone Menu (On, Off).
If your radio is operating properly but you don’t hear
tones when you press the Menu or Select buttons, your
side tones are probably disabled. Access the Side Tone
menu and reset your Tones to On.

Fine-Tuning Your Personality
Access to as many as 16 profiles within your predetermined radio personality gives you tremendous
responsiveness to the changing needs of your workday.
What’s more, within each profile, the flexibility of the
IP-protocol OpenSky network makes it possible to
fine-tune your radio’s sensitivity to incoming voice
calls by changing the Scanning Priority of specific user
groups, changing radio scanning modes and channels,
even locking out the incoming voice calls of entire user
groups.
In some ways, these sensitivity tunings are analogous
to operations familiar to users of analog equipment.
Dynamic Regrouping
In the event of an emergency, the network administrator will determine what radio users should be
formed into an ad hoc talk group to respond to the
emergent conditions.
The administrator will edit the personalities of the
affected users to include an emergency profile, then
direct the affected users to re-register with the network
to receive their edited personalities.
66
•
In response, affected users Log-On with their User
ID numbers to receive their edited personalities.
•
During Log-on, subscriber equipment will default
to the dynamically regrouped profile.
•
In all likelihood, one profile per personality will be
reserved for Dynamic Regrouping use.

Ø How to Re-Provision for an
Emergency
1.) “Punch In” your User ID when directed by the
Network Administrator.
2.) Re-registration will default to DynamicallyRegrouped Emergency Profile.
Talkaround Mode
In the absence of a nearby Base Station, in deep woods
or valleys, or in other weak coverage areas, it is
possible to work “off-network” by selecting
Talkaround Mode and placing radio-to-radio calls in
conventional FM or Project 25 Digital Common Air

CHAPTER 8—VTac Vehicular Tactical Network
Vehicular Tactical Network
The Vehicular Tactical Network (VTac-803) is an 800
MHz software-based digital mobile network repeater
for extending network coverage to portable radios,
providing scene-of-incident capability and the full
feature set of an M-803 mobile radio.
VTac supports the OpenSky communication protocol
in the 800 MHz SMR and NPSPAC frequency bands
with a high performance data modem that gateways
both voice and data to the OpenSky wide area wireless
data network.
More capable than a stand-alone M-803, the VTac-803
is a hybrid product that combines several hardware
components into a multi-use communications device to
extend the capabilities of a movable Base Station
wherever you position your vehicle.
Backward and Forward Compatibility
The software-based architecture allows the VTac-803
to be programmed for a variety of modulation
techniques, providing legacy support and guarding
against obsolescence.
VTac can host several applications simultaneously to
support users running the OpenSky digital protocol,
Conventional FM with CTCSS, or Project 25 Phase 1.
Over-the-Air Programmability
For agencies engaged in an analog-to-digital transition,
The VTac-803 can function with existing analog
infrastructure today and, when the time is right, receive
over-the-air field reprogramming for a virtually
seamless transition to fully digital communications
without replacing equipment.
82
M-803 Operator Manual
Software Version OTP 5.07
VTac Vehicular Tactical Network —CHAPTER 8
Operational Modes
By combining the functions of several components, the
VTac-803 operates in a variety of modes:
•
Mobile Radio. This is the default mode of
operation activated at Power-Up. Under ordinary
conditions, the VTac-803 is a fully-functioning
subscriber device performing all the functions of
an M-803 radio on the OpenSky network;
•
Extended Coverage. In weak coverage areas, the
VTac Base Station can be activated to act as a
mobile base station, extending OpenSky network
connectivity to portable radios in the vicinity. The
VTac continues to provide normal mobile radio
functions in Extended Coverage mode;
•
Scene-of-Incident. For radios on the OpenSky
network, VTac acts as a voice repeater in OpenSky
Trunked mode, supporting two concurrent voice
calls between subscribers at the scene;
•
Mutual Aid. For radios not on the OpenSky
network, VTac can still provide a limited set of
communication capabilities, acting in Scene-ofIncident mode as a public safety “micro-cell” to
connect users in a conventional FM Mutual Aid
network.
“A Base Station in a Trunk”
Most commonly, VTac is a trunk-mounted installation
of components that adds the most important functions
of a single-channel OpenSky Base Station to the radio
functions of an M-803 Mobile.
The VTac-803 is designed specifically with the Public
Safety user in mind. Its digital interface easily connects
to peripheral devices including the Control Head and
CAN Peripherals that are often used to support the
Public Safety mission.
Software Version OTP 5.07
M-803 Operator Manual
83
CHAPTER 8—VTac Vehicular Tactical Network
Hardware Components
The VTac-803 is a 4-piece array of hardware
components consisting of:
•
An M-803 Full Duplex Trunk Mounted Mobile
Radio Unit (MRU), also known in this
configuration as the VTac Mobile;
•
A VTac Base Unit. This component brings the
communications interface and transceiver
functionalities of an OpenSky Base Station DCX
to the trunk of a patrol car;
•
An RF combiner;
•
A CH-103 Control Head located in the passenger
compartment of the vehicle controls the three
trunk-mounted components.
Additional Control Head units may be located
elsewhere in larger vehicles for user convenience.
VTac Mobile Unit
The VTac Mobile provides the connection between the
OpenSky network, operator, mobile data terminal, and
the VTac Base Unit.
As a mobile radio, it operates like a standardinstallation M-803, providing network communications
for a single vehicle through one or more CH-103
Control Head Units.
In a VTac installation, the VTac Mobile is connected to
the VTac Base Unit by a serial cable that conducts
voice and data between the two components.
One-Button Activation
Powering Up the VTac Mobile automatically enables
all the connected hardware components of the VTac
array. Unless they’re needed, though, the RF Combiner
and VTac Base Unit stand by in a quiescent state until
called on for use.
84
M-803 Operator Manual
Software Version OTP 5.07
VTac Vehicular Tactical Network —CHAPTER 8
VTac Base Unit
The VTac Base Unit has the same transceiver and
digital controller components as the OpenSky Base
Station DCX, but in a VTac installation these
components only operate as needed, when enabled by
the subscriber.
When Extended Coverage is required, the VTac Base
Unit provides the extended connection between the
network and portable radios in the vicinity.
When Scene-of-Incident coverage is required, the
VTac Base Unit provides communication between
subscriber devices at the scene.
RF Combiner
The RF Combiner provides the VTac Network with the
ability to create an ad hoc talk group for Scene-ofIncident emergency communications.
Extended Coverage
The VTac-803 can be used as a mobile base station to
ensure that portable radios are connected to the
network at all times, in-building, or out.
Subscribers with VTac equipment can enable Extended
Coverage mode before leaving their vehicles to enter
buildings or spotty coverage areas, thereby assuring
signal strength to networked portables.
User Interaction
Extended Coverage requires subscriber activation.
Without interaction the subscriber’s mobile and
portable radios are served by the nearest network cell.
By selecting Extended Coverage mode, the subscriber
activates the VTac Base Unit as a local cell on the
OpenSky network.
Software Version OTP 5.07
M-803 Operator Manual
85
CHAPTER 8—VTac Vehicular Tactical Network
Scene of Incident
The VTac-803 can also be a vital link at the scene of an
incident, providing a repeater among OpenSky subscriber radios, or alternatively, among radios in a
Mutual Aid network that connects different radio types,
whether they subscribe to OpenSky or not.
In Scene-of-Incident (SOI) Mode, OpenSky Network
communications are sacrificed to enable full emergency connectivity between cooperating agencies at the
scene. The tradeoff of network isolation provides
increased channel capacity while relieving traffic for
other subscribers on the network.
In Scene of Incident mode with OpenSky Trunking,
VTac supports multiple talk groups. Like a tower site
base station, it continues to support agency-specific
talk groups while at the same time creating an ad hoc
talkgroup for units at the scene.
User Interaction
Scene-of-Incident coverage is not automatic. The
VTac-equipped subscriber will make an on-scene
command decision to manually activate SOI mode and
become the local cell for all calls on an ad hoc
network.
In addition, all portable radio users must select SOI
mode and tune to the VTac frequency to join the
emergency network.
Public Safety Hardened
The VTac-803 is designed specifically with the Public
Safety user in mind.
The case is manufactured with enhanced environmental
hardening making the VTac compliant with
MIL-STD-810 for temperature, altitude, solar
radiation, rain, humidity, salt, fog, sand, dust, vibration,
and shock, ensuring that it will perform under the wide
range of public safety environmental conditions.

VTac Vehicular Tactical Network —CHAPTER 8
GPS Option
The OpenSky VTac-803 can be supplied with an
optional embedded GPS receiver. GPS data can be
reported either over-the-air to remote dispatch
positions or to a local terminal connected directly to the
mobile radio.
Additionally the I/O connector provides a serial GPS
port which outputs GPS NEMA messages. Reporting
characteristics can be configured remotely and can be
event driven.
GPS functions are transparent to the subscriber and
require no user interaction.
Connectivity Interface
The VR-803 supports a variety of interfaces with its
flexible interconnect. The M-803 and VRB connect to
the RF Combiner via the antenna ports located on the
rear panel.
Peripheral Support
The rear panel also provides interfaces for both analog
and digital peripherals.
The serial RS-232 port operates in asynchronous
ASCII mode for configuration and control and switches
to Serial Line Internet Protocol (SLIP) mode for data
communication between the fixed network and a
mobile computer or terminal device.
