INTRODUCTION
1.1 GENERAL
This manual supplement is intended to be used in
conjunction with either the VHF or UHF
MCX1000 Radio service manuals described in
Section 1.3. It provides information specific to the
two printed circuit boards which provide the voice
encryption function.
While the MCX1000 Radio is available in both
digital and non-digital versions, only the digital
version of the MCX1000 supports the digital voice
encryption options.
The digital MCX1000 Radio with voice encryption
is similar both mechanically and electrically to the
digital MCX1000 Radio without encryption. The
mechnical and electrical differences are described
in Section 2 of this manual.
1.2 RADIO OPERATION WITH VOICE
ENCRYPTION
Refer to the MCX1000 Radio Service Manual for
instructions on transmitting with a voice
encrypted radio.
All switching necessary to receive an encrypted
signal is performed automatically by the radio. If
the radio receives an encrypted signal, the Coded
Signal Receive Indicator turns on. This indicator
is located to the right of the display and above the
Code 2 Select Indicator (see Figure 1-1).

2.1 MECHANICAL DESCRIPTION OF
THE VOICE ENCRYPTED MCX1000
RADIO
The mechanical description of the digital radio
may be found in the MCX1000 Radio Service
Manual.
The digital MCX1000 Radio with voice encryption
differs mechanically from a digital radio without
encryption by the addition of two printed circuit
boards (the Option Interconnect Board and the
Securenet Option Board). A mechnical extension
is made to the front of both the front mount and
remote mount radios to accommodate these two
new boards. See Figure 2-1 for the positions of the
voice encryption boards
The digital radio with voice encryption also differs
electrically from the digital radio without
encryption. In the non-encrypted dash mount
radio, the Front Panel Interconnect Board is
directly plugged into the Dash Mount Control
Head Microcomputer Board. In the voice
encrypted version of the radio, the Option
Interconnect Board is placed between the two
boards mentioned above. This Option Interconnect
Board provides the neccessary connectors to accept
SECTION 2.

CHARACTERISTICS
another board called the Securenet Option Board.
In the non-encrypted remote mount radio, the
Front Panel Interconnect Board is directly plugged
into the Remote Interface Board. In the voice
encrypted version of the radio, the Option
Interconnect Board is placed between the two
boards mentioned above. Again, the Option
Interconnect Board provides the neccessary
connectors to accept another board called the
Securenet Option Board.
2.2 ELECTRICAL DESCRIPTION OF THE
VOICE ENCRYPTED MCX1000 RADIO
The voice encrypted MCX1000 Radio is similar
electrically to the digital radio without encryption.
An electrical description of the non-encrypted radio
may be found in the MCX1000 Radio service
manual. The theory of operation for particular
boards is found at the beginning of the sections
pertaining to those boards.
The electrical descriptions of the two new boards
(Option Interconnect Board and Securenet Option
Board) are found in Section 3 of this manual
entitled Theory of Operation.

3.1 THEORY OF OPERATION - GENERAL
DESCRIPTION
The voice encryption circuits interact with a
number of other radio circuits. A description of the
characteristics of the various boards in the non-
encrypted MCX1000 Radio may be found in the
MCX1000 Radio service manual by referring to the
appropriate sections. Following is a description of
the voice encryption circuits. Figure 3-1,
Securenet Block Diagram, located at the end of this
section, supports the discussion below.
The voice encryption circuitry interfaces with the
radio audio circuits to add a high security
scrambled voice mode. Microphone audio is
digitized, transformed into cipher, and applied to
the transmitter circuits. Similarly, received cipher
is transformed into audio and applied to the
speaker. Logic circuits and audio switches allow
operation in either the private (coded) mode or the
standard (clear) mode.
The private mode employs a digital non-linear
coding scheme. Microphone audio is digitized by a
Continuously Variable Slope Delta modulator
(CVSD) whose output is applied to a non-linear
digital encryption circuit. The encrypted data is
then filtered and used to modulate the synthesizer.
In the receive mode, cipher from the discriminator
is applied to a decoder whose digital output is
converted to an analog signal by the CVSD.
A filter shapes the received audio before it is
applied to the speaker amplifier circuit.
All Motorola encryption system components (base
stations, mobiles, and portables) utilize a self
synchronizing non-linear digital voice scrambling
scheme with an extremely large capacity of
SECTION 3.
THEORY OF OPERATION
unique orthogonal codes. Once loaded, the chosen
code is internally stored and completely
unreadable. A single electronic key inserter (with
appropriate interconnect cable) allows easy code
insertion on any desired schedule. Selection of
either private or standard transmissions may be
made at the front panel by the operator.
Additional features included to ensure operator
convenience and flexibility are:
@ fully automatic selection and front panel
indication of private receive mode
@ audible alert to remind the operator
when he is initiating a non-encrypted
transmission
Options associated with voice encryption are
available to expand the performance of the
MCX1000 Radio. These are listed below.
Dual Code Select
-provides a second key selection capability
(availability restricted to a specific |
encryption type).
Proper Code Detect
-enables the radio to remain muted unless
the proper encryption code is received.
Security Housing
-_described in Section 5. of this manual.
Code Storage Battery
-provides a memory retention battery to
enable code key retention in the event that
radio power is removed. This option is
described in Section 3.2 of this manual under
the heading Option Interconnect Board.
3.2 THEORY OF OPERATION-FUNCTIONAL DESCRIPTION
Voice Encryption Definitions
Figure 3-2 below contains the definitions of terms used in the explanation of voice encryption
operation and circuitry.
TERM DEFINITION
Alert Tone Sounded at the speaker when the operator transmits in the standard mode.
The tone alerts the operator that the transmission is not encrypted. The alert
consists of a 800 Hz. tone for about 80 milliseconds.
Cipher Text Refers to the digital waveform which represents the encrypted audio.
Code The word sometimes used in place of the correct term which is key (see
key).
Code Inserter An electronic device used to load an electronic encryption key into encryption
capable radios.
Code Storage (Option MBB268) Allows the SECURENET encryption IC to retain the code if
Battery the power supply red lead to the radio is disconnected.
Crossover Jitter The ratio of crossover time (X) to whole bit time (T). See Figure 3-3. For
example, with X equal to 0.55 cm and T equal to 3.5 cm, the crossover jitter
is 15.7%.
CVSD Continuously Variable Slope Delta. The continuously variable slope delta
modulator is the IC U6102 on the Securenet Option Board schematic
diagram. Its function is to convert the digital signal to an audio signal in
receive mode and convert the audio signal to a digital signal in transmit
mode.
Decryption The conversion of cipher text to plain text.
Dual Code A second key capability. The key is stored in the Code 1 position. The
Code 2 position electronically alters the stored key. An operator control
selects either Code 1 or Code 2.
Figure 3-2 Voice Encryption Term Definitions (Sheet 1 of 3)
3-2
TERM DEFINITION
Encrypted Voice Called private mode, secure mode, cipher, or cipher text depending on the
Communication context in which the term is used. In this mode, the audio signal is converted
to a digital signal and encrypted before transmission. At the receiver, the
receiver signal is decrypted, and the resulting digital signal is used to
reconstruct the audio waveform.
Encryption The conversion of plain text to cipher text.
End-Of-Message A short burst signal of 6 kHz sine wave transmitted at the end of a private
(EOM) mode message by a voice encrypted radio. EOM lasts for the interval usually
used for the PL reverse burst signal which is about 180 milliseconds. The
EOM signal functions as a squelch closure.
Eye Opening The ratio of the minimum sample value to the overall eye amplitude
expressed as a percentage. See Figure 3-3. For example, with Y equal to
1.0 cm and Z equal to 2.5 cm, the eye opening is 40.0%.
Eye Pattern A visual representation of transmit cipher text converted by the splatter filter.
See Figure 3-3. The term eye pattern is used because the oscilloscope
trace vaguely resembles the shape of the human eye.
Idle Pattern The Signal generated by the CVSD modulator when no sound is entering the
microphone. This signal is a 6-kHz square wave.
Consists of a sequence of bits that are electronically stored in the encryption
module. The key is sometimes referred to as the electronic key to
distinguish it from a physical key such as a car key. The key is sometimes
casually referred to as a code.
Refers to the digital waveform which represents the non-encrypted audio or
decrypted audio.
Plain Text
Quality Of Received Expressed by an error rate or probability of error. This number expresses
Signal the probability that any bit that is recovered by the receiver is in error. The
error rate measures the quality of a private mode signal in much the same
way that quieting or SINAD measure the quality of a standard mode signal.
For voice encrypted radios, the error rate is usually measured for plain text
rather than cipher text since it is easier to measure. For plain text messages
to be intelligible in the voice encrypted MCX1000, the error rate should be
less than 5%.

See Figure 3-3.
Splatter Filter Converts the transmit cipher text signal to an eye pattern signal.
Also called standard mode, clear mode, bypass mode, or plain text depending on
the context in which the term is used. In this mode of operation, the audio signal
is transmitted exactly like an FM two-way radio normally transmits an audio signal.
The term sometimes used instead of end-of message (EOM).
Corresponds to the transition point between bits.
DEFINITION
Figure 3-2 Voice Encryption Term Definitions (Sheet 3 of 3)
General
The voice encryption circuitry is contained on two
boards located within the radio housing just behind
the front panel circuitry as described in Section 2.1
of this manual. The boards use CMOS integrated
circuits to perform the audio switching and control
functions which are necessary to control the
MCX1000 radio. A five pin connector at the side of
the radio allows loading of an electronic encryption
key into the voice encryption circuitry. Switches
and indicators necessary to control the voice
encryption circuitry are conveniently located on
the radio front panel.

Most of the voice encryption circuitry is contained
on the Securenet Option Board. However, the
Option Interconnect Board provides the functions
described below.
@ Battery BT6000 (see Figure 4-3 for part
number) which supplies continuous voltage
to encryption hybrid U6103 (U6103-3) on
the Securenet Option Board to retain the
code key if radio power is removed. This
battery is shown in Figure 4-1 (component
side) and Figure 4-2 (schematic).
@ U6002B amplifier circuit receives RX BUS
AUDIO from the Securenet Option Board,
amplifies it and sends it through the Front
Panel Interconnect Board (as RX OPTION
SUMMER), through the Analog Interface
Board and further on to audio circuits on
the Main Board.
@ U6001, U6003 and associated circuitry
constitutes a series of cascaded amplifiers
and band-limiting filters which pass
microphone audio (MIC AUDIO) from
J366A-6 to the Securenet Option Board via
P6003-3. The primary signal gain occurs in
the first stage (U6001A).
@ U6000A amplifies discriminator audio
(DISC AUDIO) from J366A-17 and sends it
to the Securenet Option Board as AMP
DISC AUDIO via P6002/P6003-4.
Voice Encrypted Signal Routing
In the discussion following, reference is made to
Figure 3-1 (Securenet Block Diagram) and Figure
4-5 (Securenet Option Board Schematic Diagram).
The voice encryption circuitry controls both the
receive and transmit portions of the MCX1000
radio. When the radio is receiving, the voice
encryption circuitry checks the signal. If the signal
is coded, decrypted audio is routed to the radio
speaker. If the signal is not coded, discriminator
audio is routed to the radio speaker. When the
radio is transmitting, the voice encryption circuitry
routes either IDC audio or encrypted cipher to the
radio modulating circuitry, depending upon the
front panel mode setting.
Buffered discriminator output is routed to the voice
encryption circuitry for code detection and audio
reconstruction. The discriminator audio enters the
board at J6003-4 as AMP DISC AUDIO. It first
passes through an analog gate (U6105B), an
equalizer (U6104B), and is then applied to U6100,
where the signal is processed to recover the receive
cipher and synchronize the clock. This IC also
detects whether or not the discriminator signal is
actually an eye pattern so that it can control the
receive audio gates. Cipher text then goes to pin 9
of the encryption hybrid (U6103) via the RX
CIPHER line where it is decrypted to produce the
plain text. The plain text is routed (via the RX
DATA line) to the CVSD modulator U6102, where
the plain text is converted to an audio signal. This
reconstructed audio is output from the CVSD
modulator (via U6102-15) and routed back into the
radio low level audio path by passing through
analog switch U6105D to J6003-6 as RX BUS
AUDIO. Microcomputer U6101 controls analog
switch U6105D by the DECODE AUD ENABLE
line (U6101-29). RX BUS AUDIO enters the
Option Interconnect Board through P6003-6, where
the signal proceeds to op amp U6002A and on to
J366A-16 (RX OPTION SUMMER) to the Front
Panel Interconnect Board. From this board the
signal is routed to the Analog Interface Board and
on to the OPT PLAY DE-EMPH GATE which is
“on” for a coded signal. From this point on the
Analog Interface Board, the signal passes through
the PL high pass filter and then on to the de-
emphasis amplifier on the Main Board.
If the incoming signal is not encrypted, the signal
path may be traced by referring to the Receiver
Audio Block Diagram in the MCX1000 Radio
service manual. After leaving the detector buffer
on the Main Board, the discriminator audio (DISC
AUDIO) passes through the DISC AUDIO MUTE
GATE (on the Analog Interface Board). The signal
then enters the PL high pass filter on the Analog
Interface Board and proceeds to the De-emphasis
amplifier on the Main Board.
When transmitting in the encryption mode, the
MIC AUDIO MUTE GATE on the Main Board is
turned off. Mic audio is routed through J6003-3,
(MIC AUDIO) to U6104A where it is pre-
emphasized, limited and filtered and then to the
encryption circuitry to be digitized by the CVSD
modulator (U6102). The CVSD modulator converts
the audio waveform to a 12-kbps digital signal.
This digital signal (the plain text) then goes to the
encryption hybrid (U6103) by means of the TX
DATA line (U6103-17). The hybrid encrypts the
plain text to produce cipher text which enters the
Control and Interface IC on the TX CIPHER line
(U6100-25). The cipher text passes through a
splatter filter within U6100 and exits through pin
2.
U6101-28, TX AUD ENABLE, controls the analog
gate, U6105C, and allows the encrypted signal to
pass through the deviation adjustment potentio-
meter, R6109. From potentiometer R6109, the
encrypted signal passes through J6003-10 as TX
BUS AUDIO. From this point, the signal crosses
the Option Interconnect Board and enters the Front
Panel Interconnect Board. After passing through a
summing amplifier (U350B) on the Front Panel
Interconnect Board, the signal proceeds to the
Analog Interface Board. On the Analog Interface
Board, the signal passes through the OPT TX
FLAT GATE, then through an op amp before
leaving the Analog Interface Board on the VCO IN
line.
When transmitting in clear mode, refer to the
Transmitter Audio Block Diagram in the
MCX1000 Radio Service Manual for the audio
path. Also, reference is made to the clear mode
audio path in the appropriate board theory notes
found in the MCX1000 Radio Service Manual.

Key Insert Circuit
The key insert circuit allows an electronic key to be
inserted into the encryption IC. The circuit is
composed of three signal lines that are routed from
the cable connector on the side of the radio to the
Option Interconnect Board. The WE signal (P6100-
7) goes directly to the encryption hybrid U6103 (pin
4) through R6166; WE goes low when a key is being
loaded. The KEY signal (P6100-6) goes to the
microprocessor and to the encryption hybrid,
U6103. The microprocessor uses this line to
determine when a key is being loaded in order to
gate the verification tone to the RX AUDIO path.
The KID signal (P6100-8) goes to the control and
interface IC, U6100, to synchronize the clock with
3-6
the bits of the key insert signals. After the key is
transferred to the radio, the key inserter sends an
encrypted tone (verification tone) on the KID line
to signal that a key has been transferred
sucessfully.
If the radio is keyed in the encrypted mode, and if
the encryption hybrid does not contain a valid key,
no transmission takes place. In addition,
depending on the type of encryption hybrid
installed in the radio, there may be another
indication of key loss. This indication consists of
pulses of a 750 Hz. tone (100ms on, 100ms off) while
the PTT button is activated, as well as the radio
front panel display showing the phrase “NO KEY”
for approximately 3 seconds after key-up.

SECURITY HOUSING
INFORMATION
5.1 GENERAL
The MCX1000 Security Housing may be used with
any MCX1000 Digital Capable Radio with voice
encryption, including units equipped for Base
Station operation. The security housing provides
the following features:
e An anti-tamper switch which erases the key
variable stored in the encryption hybrid if an
attempt is made to disassemble the housing.
e An erase button so that the same erase
procedure mentioned above may be carried out
manually by the radio operator.
e A key operated switch (called the keyload
switch) which prevents unauthorized loading
of a new key variable into the encryption
hybrid.
e A key operated switch (called the
operate/standby switch) which prevents
unauthorized use of the voice encryption
capability while allowing normal operation in
the clear (non-encrypted) mode.
e A mechanical enclosure around the MCX1000
Radio which resists attempts to either remove
the top and bottom covers of the main radio
chassis or remove the radio from its location.
5.2 JUMPERING INFORMATION
When a security housing is used, jumper JU6104 on
the Securenet Option Board is removed. This allows
the operate/standby switch on the security housing
to operate properly. JU6104 is located near plug
P6100.
5.3 INSTALLATION
MOBILE APPLICATIONS
Refer to Figure 5-1 when mounting the security
housing and the radio in a vehicle. This figure
shows an exploded view of the mounting hardware
required, which is contained in MBTRN4675A,
Standard Mounting Hardware Kit. The security
housing hardware for mobile applications is
contained in VLN4141A.
Perform the steps below to mount the radio and
security housing into the vehicle.
1. Position the bottom tray of the security
housing (part # 0782633P01) with the radio
mounting tray so that the four screw holes are
aligned. Make sure the security housing
bottom tray is placed underneath the radio
mounting tray. Secure both trays to the
desired location, using the four 10-16 screws,
flat washers, and lock washers provided.
2. Position the radio into the mounting tray,
aligning the four radio mounting holes with
the holes in the sides of the tray.
3. Position the main security housing (part #
1582632P01) so that one side fits snugly into
the security housing bottom tray. Make sure
that the ground strap from the security
housing makes direct contact with the radio
chassis, as illustrated in Figure 5-1.
4. Fasten the four mounting tray screws into the
sides of the radio.
5. Take the key loading cable (located on the side
of the radio) and plug it into the 10 contact
receptacle located inside the main security
housing.

SECTION 5.
SECURITY HOUSING
INFORMATION
5.1 GENERAL
The MCX1000 Security Housing may be used with
any MCX1000 Digital Capable Radio with voice
encryption, including units equipped for Base
Station operation. The security housing provides
the following features:
e An anti-tamper switch which erases the key
variable stored in the encryption hybrid if an
attempt is made to disassemble the housing.
e An erase button so that the same erase
procedure mentioned above may be carried out
manually by the radio operator.
e A key operated switch (called the keyload
switch) which prevents unauthorized loading
of a new key variable into the encryption
hybrid.
e A key operated switch (called the
operate/standby switch) which prevents
unauthorized use of the voice encryption
capability while allowing normal operation in
the clear (non-encrypted) mode.
e A mechanical enclosure around the MCX1000
Radio which resists attempts to either remove
the top and bottom covers of the main radio
chassis or remove the radio from its location.
5.2 JUMPERING INFORMATION
When a security housing is used, jumper JU6104 on
the Securenet Option Board is removed. This allows
the operate/standby switch on the security housing
to operate properly. JU6104 is located near plug
P6100.
5.3 INSTALLATION
MOBILE APPLICATIONS
Refer to Figure 5-1 when mounting the security
housing and the radio in a vehicle. This figure
shows an exploded view of the mounting hardware
required, which is contained in MBTRN4675A,
Standard Mounting Hardware Kit. The security
housing hardware for mobile applications is
contained in VLN4141A.
Perform the steps below to mount the radio and
security housing into the vehicle.
1. Position the bottom tray of the security
housing (part # 0782633P01) with the radio
mounting tray so that the four screw holes are
aligned. Make sure the security housing
bottom tray is placed underneath the radio
mounting tray. Secure both trays to the
desired location, using the four 10-16 screws,
flat washers, and lock washers provided.
2. Position the radio into the mounting tray,
aligning the four radio mounting holes with
the holes in the sides of the tray.
3. Position the main security housing (part #
1582632P01) so that one side fits snugly into
the security housing bottom tray. Make sure
that the ground strap from the security
housing makes direct contact with the radio
chassis, as illustrated in Figure 5-1.
4. Fasten the four mounting tray screws into the
sides of the radio.
5. Take the key loading cable (located on the side
of the radio) and plug it into the 10 contact
receptacle located inside the main security
housing.
6. Place the angled end of the side plate (part #
1582631P01) into the security housing bottom
tray. Close the side plate and fasten it to the
housing by means of the two 6-32 X 4” screws
and #6 lock washers provided. This completes
the installation of the security housing.
BASE STATION APPLICATIONS
Figure 5-2 gives an exploded view and parts list for
VLN5190A which is a part of the Security Base
Station Tray Kit, VLN1156B. VLN5190A is
assembled prior to shipping and is illustrated for
reference only. If desired, the security housing
assembly may be secured to a suitable mounting
surface by placing two #10 X 32” screws (reference
#2 of Figure 5-2) through the mounting
tray/speaker housing assembly and into pre-drilled
holes in the mounting surface. To mount the base
station radio into the security housing and
mounting tray, perform the above steps describing
mobile installations, beginning with step #2.
5.4 OPERATING INSTRUCTIONS
Radio operation depends in some ways on the type of
encryption being used in the radio. Also, differences
in operation occur with radios equipped with the
security housing. These differences are described in
the following paragraphs.
KEY INSERTION INFORMATION
To load a key variable into a radio equipped with the
security housing, the Keyload Switch must be in the
“Keyload” position. Also, the Operate/ Standby
Switch must be in the “Operate” position.
Instructions for loading a key variable into an
MCX1000 Radio are provided in separate
instruction manuals specific to the Key Code
Inserter being used.
TRANSMIT AND RECEIVE OPERATION
For radios equipped with the security housing, the
Operate/Standby Switch must be in the “Operate”
position in order to transmit or receive messages in
the encrypted mode. Standard messages (non-
encrypted) may be transmitted and received with
the switch in either position.
KEY LOSS INDICATION
Refer to Section 3.2 (under the heading Key Insert
Circuit) for information regarding indications of loss
5-2
of the key code in the voice encrypted MCX1000
Radio.
ERASE BUTTON
For radios equipped with the security housing, an
Erase Button is provided on the security housing so
that the radio operator may set the key variable in
the radio to zero. Erasing occurs regardless of the
position of any other switch, including the ON/OFF
switch. The radio does not transmit or receive
encrypted messages until another key has been
transferred to the radio.
5.5 SECURITY HOUSING
EXPLODED VIEW
Figure 5-3 shows the Security Housing Exploded
View and gives a parts list for the VLN5189A (Base
Station) and VLN4141A (Standard) Security
Housings. VLN5189A is identical in content to
VLN4141A except that part # 0782633P01 has been
moved to VLN5190A, Security Base Station
Mounting Tray Kit to facilitate assembly of the
mounting tray kit prior to shipment. Both
VLN5189A and VLN5190A are contained within
VLN1156B, Security Base Station Tray Kit.
SECURITY HOUSING WIRING DIAGRAM
Figure 5-4 shows the security housing wiring
diagram, which is a part of VLN4141A/VLN5189A .
5.6 SERVICING
Special procedures are required for servicing radios
equipped with the security housing. These
procedures must be used, and are required if the
radio is to be operated in the encrypted mode while
the security housing is removed.
To operate the radio in the encrypted mode with the
security housing removed, first reconnect the
keyload cable. Then, with the security housing
removed, secure the side security housing plate to
the main radio housing with the supplied screws.
With the side security housing plate in place, the
anti-tamper switch is depressed. This allows for
encrypted mode operation of the radio as if the
security housing was in place around the radio.
To reassemble the radio, it is necessary to remove
the side security housing plate. This action
activates the anti-tamper switch which erases the
key variable used during servicing or testing.
