1.2 TRANSCEIVER DESCRIPTION
1.2.1 GENERAL
The 5300 series mobile transceivers can operate
on various types of channels and with various signaling
protocols (see following information). Models are
availablefor operation in the followingbands.Repeater
talk-around is also available with all bands.
VHF 136-174 MHz (35-watt models)
146-174 MHz (100-watt models)
UHF 380-470 MHz (Federal users only)
403-470 MHz
800 MHz 806-870 MHz (see following)
Power Output
Power output is user switchable for low and high
levels in the following ranges:
VHF 10-50W standard version,
50-100W high-power version
UHF 7-15W low power version*
10-40W med power version*
800 MHz 10-35W
*Version A and B models are available in the 15W configu-
ration only, and Version C models are available in the 40W
configuration only (see Section 1.12 for Version A/B/C
information).
1.2.2 ANALOG/DIGITAL OPERATION
The 5300 transceivers use a digital signal
processor (DSP) to provide IF and audio filtering and
signal modulation functions. This allows operation on
the following types of channels, backwards compati-
bility with existing equipment, and also the ability to
operate on various types of radio systems.
Narrow Band Analog - FM modulation is used with a
maximum deviation of 2.5 kHz. This mode is usually
used in systems with a channel spacing of 12.5 or
15 kHz.
Wideband Analog - FM modulation is used with a
maximum deviation of 5 kHz. This mode is usually
used in systems where the channel spacing is 25 kHz
or 30 kHz.
Project 25 Digital - Operates on Project 25 compatible
systems. The voice is digitized, error corrected,
optionally encrypted, and then transmitted using
C4FM modulation according to the Project 25 stan-
dard. This mode uses a channel spacing of 12.5 kHz.
1.2.3 OPERATING PROTOCOLS
The 5300 transceivers can be programmed for all
the following operating protocols. The conventional
analog protocol is standard and the others are optional
(available only if enabled by factory programming).
Refer to Section 3 for more operation information.
•APCO Project 25 (digital) conventional
•APCO Project 25 (digital) trunked

GENERAL INFORMATION
1-2
•SMARTNET®/SmartZone®trunked analog or
digital
•Analog conventional
NOTE: Multi-Net operation can be programmed with
Ascend models only.
1.2.4 AVAILABLE MOUNTING OPTIONS
Front Mount - The operating controls are on the front
on the radio, so the radio must be mounted within
reach of the user.
Remote Mount, Single Control Unit - The operating
controls are located on a remote mounted control unit.
The radio does not have operating controls.
Remote Mount, Dual Controls - A remote control
unit is connected to the front mount radio. This allows
control from the front panel and the remote control
unit.
Remote Mount, Dual Remote Control Units - Two
remote control units are connected to the remote
mount radio. This allows control from both remote
control units.
1.2.5 SYSTEMS, CHANNELS, AND ZONES
A zone and channel are selected to place and
receive calls. The following describes the relationship
between systems, channels, and zones.
Systems
A system is a collection of channels or talk
groups belonging to the same repeater site. It defines
all the parameters and protocol information required to
access a site. Up to 16 systems of any type can be
programmed. The maximum number of channels
assignable to a system is limited to approximately 256
(or the available memory space as described in the
following information).
Channels
A channel selects a radio channel or talk group in
a system as follows:
Conventional Analog Mode - A channel selects a
specific radio channel, Call Guard (CTCSS/DCS)
squelch coding, and other parameters unique to that
channel.
Conventional Project 25 Mode - A channel selects a
specific radio channel, NAC squelch coding, talk
group ID, and other parameters unique to that channel.
Trunked Project 25 Mode - A channel selects a
specific talk group ID and other parameters unique to
that talk group.
SmartNet/SmartZone and Project 25 Trunked
Operation - A channel selects a specific talk group,
announcement group, emergency group, and other
parameters unique to that talk group.
As previously described, a maximum of up to 256
channels can be programmed. Although it is theoreti-
cally possible to program any combination of systems
that produces up to 256 total channels, the maximum
number may be limited by the available memory. For
example, since more memory is required to program a
SMARTNET system than a conventional system, the
total number of channels decreases as the number of
SMARTNET systems increases. The programming
software displays a bar graph which shows the amount
of available memory space that is used by the current
data. Refer to Section 4 for more information.
Zones
A zone is a collection of up to 16 channels of any
type. For example, a zone could include 12 conven-
tional channels and 4 SMARTNET channels. One use
of zones may be to program the channels used for
operation in a specific geographical area. Up to 16
zones can be programmed.
1.2.6 PROGRAMMING
Transceiver programming is performed using a
PC-compatible computer and an EFJohnson RPI
(Remote Programming Interface) and PCConfigure
programming software (see Table 1-1). Programming
is described in a separate included manual. Refer to
Section 4 for more information.
1.2.7 ALIGNMENT
Transceiver alignment is performed using the
same computer and RPI used for programming (see

GENERAL INFORMATION
1-3
preceding section) and special PCTune™software. All
adjustments are made electronically using the software
(no manual adjustments are required). Alignment is
described in Section 6.

NOTE: Refer to Section 11 of the 5300 Operating
Manual for more information on secure communica-
tion. A link to the operating manual is located in
Section 3 of this manual.
1.11.1 GENERAL
SecureNet™ and AES voice encryption are used
to provide secure communication with this transceiver.
These protocols digitize the voice and then encrypt it
using a DES or AES algorithm. The following types of
encryption are available on analog and digital
channels:
Analog Conventional and SMARTNET/Smart-
Zone Analog Channels
•DES
•DES-XL (5300 versions with UCM module
only; see Section 1.12.2)
Digital Project 25 and SMARTNET/SmartZone
Channels
•DES-OFB (Output Feedback)
•AES (Advanced Encryption Standard). Later
5300 models only. Refer to Section 11 of the
5300 OperatingManual for more information (a
link is located in Section 3).
1.11.2 FIPS 140-2 APPROVED ENCRYPTION
All encrypted 5300 models are FIPS certified for
the DES-OFB and AES encryption modes. Encryp-
tion on analog channels is not FIPS certified. FIPS
140-02 is a Federal Information Processing Standard
recently approved by the United States Secretary of
Commerce. This standard specifies Federal security
requirements for cryptographic modules for a wide
range of applications and environments.
1.11.3 OVER-THE-AIR-REKEYING (OTAR)
Encryption keys are loaded into the radio by
OTAR (Over-The-Air-Rekeying) using a KMF (Key
Management Facility) and/or a handheld keyloader
such as the EFJohnson SMA (Subscriber Manage-
ment Assistant) or Motorola KVL 3000 Plus with the
AES option.
The keyloader is connected directly to the radio
using an interconnect cable, and it loads DES, DES-
OFB, and AES keys. Currently, OTAR can be used to
load DES-OFB keys on Project 25 conventional chan-
nels. Future OTAR of AES keys and on Project 25
trunked channels is planned. Refer to Section 11 of the
5300 Operating Manual for more OTAR information.
A link to this manual is located in Section 3 of this
manual.
1.11.4 KEY RETENTION
NOTE: The 5300 radio has a security feature (push-
button switch S1 on the logic board) that automati-
cally erases the encryption keys when the bottom cover
is removed (except when Infinite Key Retention is
programmed as follows).
If Infinite Key Retention Infinite Key Retention
is programmed, the keys are maintained in memory
indefinitely, even without power applied. If it is not
programmed, the transceiver must be connected to an
unswitched power source to preserve the encryption
keys in memory. However, a storage capacitor (C173,
0.22 F) maintains the 5-volt supply (and the encryp-
tion keys) for approximately 8 hours if power is
temporarily lost.

1.12 RADIO HARDWARE CHANGES
NOTE: Version A/B/C references in the following
information are for descriptive purposes in this
manual only and do not correspond to any radio
revision letters or letters on the boards.
1.12.1 RF MODULE CHANGES
As shown in Figure 1-1, there have been three
significant changes to the 5300 RF module. More
information on each of these versions follows.
Version A - This is the original version that was used
until approximately late 2003. All versions of PCTune
can be used to tune radios with these modules. The
schematic diagrams and board layout for this version
of the VHF board are located in the Early_Bds folder
and the other boards are located in Section 8.
Version B - The changeover to this version occurred
starting in late 2003. This change was made because of
parts obsolescence. Significant changes occurred to
only the VHF board, so this is the only board with
revised schematics and layouts in this manual. With
the UHF and 800 MHz boards, only minor layout and
value changes occurred. The Version B boards are
being replaced by the following Version C boards as
they become available.
NOTE: PCTune, Version 1.10.0 or later must be used
to tune VHF radios with this board (see following).
PCTune Version 1.10.0 or later must be used to
adjust radios with this version VHF board because of
changes made in the front end. The earlier PCTune
version (1.0.8.9) can still be used to tune all other
Version B and all Version A boards.
The Revision Letter in the radio identification
number (see Section 1.5) can be used to determine if a
VHF radio has this new Version B board. Radios with
a revision letter of “H” or later have the new board and
PCTune 1.10.0 or later must be used.

DES DES-XL DES-OFB AES
Version 1 (Uses early Motorola UCM module)
This is the ARM logic version which uses a differ-
ent UCM module than is used in Version 3 which
follows. This version is no longer available and uses
the 035-1800-4xx Version C logic board.
1.xx (both
DSP and
ARM code
required)
Yes Yes Yes Yes
Version 2 (uses EFJ SEM module)
Current version which has the EFJohnson SEM
(Subscriber Encryption Module) on the logic board.
This version uses the 035-5300-600 Version B logic
board. All radios include the SEM, and the desired
encryption options (if any) are enabled by factory
programming. FIPS approved.
2.xx Yes No Yes Yes
Version 3 (uses Motorola UCM module)
Current version (B) which has the Motorola UCM
(Universal Crypto Module) on the logic board. This
version also uses the uses the 035-5300-600 Version
B logic board with the addition of a few parts. This
version is ordered when DES-XL encryption is
required. FIPS approved.
3.xx Yes Yes Yes Yes
Version 4 (uses EFJ SEM module)
New version (C) designed for use with new RF
modules. It uses the same EFJohnson SEM (Sub-
scriber Encryption Module) as Version 2 boards
above. This version uses the 035-5500-600 Version
C logic board. All radios include the SEM, and the
desired encryption options (if any) are enabled by
factory programming. FIPS approved.
4.xx Yes No Yes Yes
Version C - These boards are a completely new
design. Highlights of this board version are as follows:
•Becauseofdifferentinterfacerequirements,thenew
Version C logic board described in the next section
must be used with these RF boards.
•A new version of the PCTune software (2.0 or later)
is required to tune radios with these boards.
•The new 800 MHz version of this board (not
currently available with 53xx) operates on both 700
and 800 MHz channels instead of only 800 MHz
channels like the A and B versions. Therefore,
radios with the Version C board can operate on
channels from 762-870 MHz, while radios with the
earlier Version A and B boards can operate only on
channels from 806-870 MHz.
Radios with this new 700/800 MHz RF board have
a “7” as the “F” character of the radio part number
(see Section 1.4), while radios with the older A and
B versions have an “8” for this character.
1.12.2 LOGIC BOARD CHANGES
As shown in Figure 1-1 and Table 1-2, there have
been three significant changes to the control logic used
in 53xx series radios. More information on these
changes follows.
NOTE: The firmware version number (1.x/2.x/3.x) is
the second number briefly displayed when radio power
is turned on (the first number is for the control unit).
Version A - This version uses ARM processor-based
control logic, and the PC board is Part No.

GENERAL INFORMATION

035-1800-42x. This board has a jack for plugging in
various Motorola encryption modules that provide
DES/DES-XL/DES-OFB and AES encryption. It does
not use the SEM module. This service manual includes
schematic, board layout, and parts information for this
and an even earlier -40x version of this board. This
board is no longer shipping in new radios and has been
replaced by the following PPC versions.
Radios with this logic board have Version 1.x
firmware (see Table 1-2). Both DSP and ARM code
files may be required to update the firmware.
Version B
Beginning in November 2003, a revised logic
board began shipping in 53xx models. This board
utilizes a Power PC (PPC) control logic design similar
to that used in the 51xx portable. This board is avail-
able in the following configurations:
SEM Version - This version has the EFJohnson
SEM (Security Encryption Module) soldered to the
board. It is used whenever DES, DES-OFB, or
AES encryption is required. DES-XL encryption is
not available with this version. Radios with this
logic board have Version 2.x firmware (see
Table 1-2).
UCM Version - This version includes a plug-in
Motorola UCM encryption module instead of the
SEM. It is used whenever DES-XL Motorola
proprietary encryption is required. It also provides
DES, DES-OFB, or AES encryption. Other differ-
ences between this board and the SEM version are
that it has a jack for plugging in the module (J2)
and an additional PLC IC (U82). Radios with this
logic board have Version 3.x firmware (see
Table 1-2).
The part number of the Version B logic board is
035-5300-600. The same PC board is used for both of
the preceding configurations (each version is popu-
lated differently). This service manual includes sche-
matic, board layout, and parts list information for this
new logic board.
Radios with the new PPC revised logic board
have a Revision Letter of “G” or higher in the serial
number. Radios with the early -400/-410 ARM logic
board have a A-F Revision letter. Refer to the radio
Serial Number on the label on the bottom cover to
determine the Revision Letter (see Section 1.5).
Version C - This version of the logic and UI boards is
a new design that is required to interface with the new
Version C RF module. Only a SEM version is being
offered (similar to Version 2 in Table 1-2). This
version of board has more Flash and RAM memory to
allow additional features to be added if necessary.
Radios with this logic board have Version 4.x.x firm-
ware (see Table 1-2).

changes that were included in the -004 5300 Service
Manual with a printing date of March 2002. That manual
replaced the -003 manual which had a printing date of
March 2000.
PCConfigure Programming Software
The PCTrunk programming software has been
replaced with PCConfigure. This software has an
entirely new user interface (programming screens)
although the information programmed is basically the
same. PCConfigure is required to program many of the
features in current models, so it is recommended that
you upgrade to PCConfigure. Refer to Section 4 for
more information on the PCConfigure software.
New Logic Board
The logic board is a new design with different
parts and layout. The schematic and board layout in
this manual have been updated with this new board.
Information for the earlier boards is included in the
Early_Bds folder on the CD-ROM.
This new logic board is Revision 5 or later, and it
provides a new optional enhanced “Over The Air Re-
Keying” (OTAR) feature for use with SecureNet
encryption. The Revision 6 or later board is required to
use the currently available UCM encryption module
(see Section 1.6).
Models with the Revision 6 or later logic board
have a revision later of “G” or higher (standard power
models) or “B” or higher (100W VHF models). Refer
to Section 1.5 for more revision letter information.
New RF Boards
A new VHF RF board is being used and a new
800 MHz RF board is being phased in. These boards
have a new pin out arrangement that requires a short
ribbon cable and new interconnect board design.
Section 8 includes the schematics and layouts for the
revised boards, and Early_Bds folder on the CD-ROM
includes this information for the unrevised boards.
Models with the new RF board have a revision
later of “H” or higher (standard power models) or “C”
or higher (100W VHF models). Refer to Section 1.5
for more revision letter information.
New VHF (50W) PA Board
A newly designed PA board is now being used.
The main change to this board was converting several
mini mica capacitors to ceramic type. Tap points were
also added for the cables to the 100W PA board when
it is used. The schematic and layout for this new board
is included in this manual, and the earlier board is
included in the Early_Bds folder on the CD-ROM.
New VHF 100W Models
This manual includes installation and servicing
information for the new 100W VHF transceiver. This

GENERAL INFORMATION
1-14
transceiver includes an additional PA deck on the back
which contains a new 100W PA board.
New Display Controller Board
A running change is being made to a new display
controller board. The new board uses a different
microcontroller and allows the control head operating
software to be re-Flashed through the front panel
microphone jack. Information for the earlier board is
included in the Early_Bds folder on the CD-ROM.
Handheld Control Unit
A Handheld Control Unit is now available. This
control unit has all user controls and the display in a
compact unit similar in size to a microphone. It
replaces the standard remote control unit in remote
mount applications. An external speaker is required
because it does not have an internal speaker. An
optional junction box is available that has jacks for
earphone/microphone, line out, speaker out, and trans-
ceiver programming. Installation, operation, and
servicing information for this control unit are included
in this manual.
Siren
A siren option is now available that operates with
the 5300 transceiver. The transceiver microphone is
used for the siren PA function, and receive audio can
be routed through the siren loudspeaker and the
volume controlled by the transceiver volume switch.
In addition, the siren controller backlight is controlled
by the transceiver.
To provide siren control, a siren control pigtail
cable must be installed in the transceiver. To accom-
modate this cable, J6 has been added to the logic board
(Revision 6 or later) and J201 has been added to the
interface board. Installation information for the siren
controller is included in this manual.
New Features (see Section 3)
•A Selective Squelch option switch can now be
programmed with conventional analog and digital
(P25) operation. This switch allows the CTCSS/
DCS/NAC code to be selected from a prepro-
grammed list.
•A Hardware Key Select option switch in now
programmable with SecureNet encryption. This
switch allows the hardware keys to be manually
selected.
•The transceiver can now be programmed so that a
password must be entered at power-up to make the
transceiveroperational.Thispreventsunauthorized
use.
