VI. Patent And Software Provisions
MOTOROLA will defend, at its own expense, any suit brought against the end user purchaser to the
extent that it is based on a claim that the Product or parts infringe a United States patent, and
MOTOROLA will pay those costs and damages finally awarded against the end user purchaser in
any such suit which are attributable to any such claim, but such defense and payments are
conditioned on the following:
A. that MOTOROLA will be notified promptly in writing by such purchaser of any notice of such
claim;
B. that MOTOROLA will have sole control of the defense of such suit and all negotiations for its
settlement or compromise; and
C. should the Product or parts become, or in MOTOROLA’s opinion be likely to become, the
subject of a claim of infringement of a United States patent, that such purchaser will permit
MOTOROLA, at its option and expense, either to procure for such purchaser the right to con-
tinue using the Product or parts or to replace or modify the same so that it becomes nonin-
fringing or to grant such purchaser a credit for the Product or parts as depreciated and accept
its return. The depreciation will be an equal amount per year over the lifetime of the Product
or parts as established by MOTOROLA.
MOTOROLA will have no liability with respect to any claim of patent infringement which is based
upon the combination of the Product or parts furnished hereunder with software, apparatus or
devices not furnished by MOTOROLA, nor will MOTOROLA have any liability for the use of ancillary
equipment or software not furnished by MOTOROLA which is attached to or used in connection with
the Product. The foregoing states the entire liability of MOTOROLA with respect to infringement of
patents by the Product or any parts thereof.
Laws in the United States and other countries preserve for MOTOROLA certain exclusive rights for
copyrighted MOTOROLA software such as the exclusive rights to reproduce in copies and distribute
copies of such Motorola software. MOTOROLA software may be used in only the Product in which
the software was originally embodied and such software in such Product may not be replaced,
copied, distributed, modified in any way, or used to produce any derivative thereof. No other use
including, without limitation, alteration, modification, reproduction, distribution, or reverse
engineering of such MOTOROLA software or exercise of rights in such MOTOROLA software is
permitted. No license is granted by implication, estoppel or otherwise under MOTOROLA patent
rights or copyrights.

1-2 Introduction: Control Head Descriptions
ASTRO Digital Spectra and Digital Spectra Plus radios are available in five models. Table 1-1
provides a description of basic features for the five models covered in this manual.
1.2.1 FLASHport®
The ASTRO Digital Spectra and Digital Spectra Plus radios utilize Motorola’s revolutionary
FLASHport technology. FLASHport makes it possible to add software that drives the radio’s
capabilities both at the time of purchase and later on. Previously, changing a radio’s features and
capabilities meant significant modifications, or buying a new radio. But now, the radio’s features and
capabilities can be upgraded with FLASHport software, similar to the way a computer can be loaded
with different software.
1.3 Control Head Descriptions
1.3.1 General
The control heads used with ASTRO Digital Spectra and Digital Spectra Plus radios have
microprocessor circuitry that operates the standard and optional features built into the system. The
control head design allows installation in even the smallest of vehicles. Systems that have many
options require more control head buttons, not larger control heads.
The control heads may be field-programmed to add options or alter the information stored in certain
areas of its electronic memory.
The following illustrations show some typical ASTRO Digital Spectra and Digital Spectra Plus control

Introduction: Control Head Descriptions 1-5
Figure 1-5. Typical W9 Pushbutton Control Head
1.3.1.4 Models W4, W5, W7, and W9 Controls
Power Switch — The power (PWR) switch turns the radio and its accessories on or off. The
power switch is part of the rotary volume knob on the W4 model, a push-type switch on the W5
and W7 models, and a slide switch on the right-hand bottom surface of the W9 model.
Mode Switch — The Mode switch is used for selecting modes and programming menus. The
Mode switch is a rotary switch on the W4 model and a rocker switch on the W5, W7, and W9
models. Pressing the right side of this rocker switch increases the mode number. Pressing the
left side decreases the mode number. If you press and hold the switch, it scrolls the mode
number up or down. The mode names appear in the display window.
Volume Switch — The Volume switch is used for selecting the volume level, editing names, and
making certain radio adjustments. The Volume switch is a rotary switch on the W4 model and a
rocker switch on the W5, W7, and W9 models. On the pushbutton models, pressing and
releasing the volume switch checks the volume setting. Your display will show “VOLUME_ _”
and a number value (0-15). Press and hold the left side to decrease the volume. The number
value scrolls up or down to your desired level. The Volume rocker switch also controls the
volume level of the public address (PA) and external radio speaker (Ex Rd) options when they
are enabled. The display window shows “PA VOL _ _” when public address is on and the
Volume rocker switch is pressed.
Dim Button — The DIM button is used to control the brightness of the display and button
backlighting. When you turn on the system, the display comes on at the brightness level it was
on before the system was last turned off. Press the DIM button once to reduce the brightness of
the display to medium level and twice for low brightness level. Press the DIM button a third time
to turn the display and button backlighting off. This is called the “surveillance” mode.
Home Button — The Home button is used for restoring preprogrammed mode, establishing
programmed mode, selecting programming entries, etc. Press the Home button to go to the
radio’s preprogrammed “home” mode. On the W7 models, you may use the Home button
instead of Mode switch to change modes. Hold the Home button until a beep sounds to enter
the configuration state. The display shows an entry prompt. Use the keypad to enter your new
mode choice and press the Home button again. Your mode is now changed without scrolling.
Select Button — The Sel button is used to configure radio options.

Option Buttons — The option buttons are used for turning options on and off, such as Phone,
Scan, Emergency Call, and Secure.
Display — The vacuum fluorescent (VF) display’s primary function is to display mode numbers,
mode names, volume level, and the status of options. It also functions as an on-off indicator for
the entire system and plays an integral role in the operator’s reconfiguration of options. The
display is 8 characters on W4, W5, and W7 models; 11 characters on the W9 model.
XMIT and BUSY Indicators — The XMIT indicator lights when the radio is transmitting. The
BUSY indicator lights when the selected channel is busy.
Scan Indicators — When scan operation detects activity on a non-priority (NON-PRI) channel,
the NON-PRI indicator light comes on. Activity on a second priority channel causes the priority
(PRI) indicator to light. First priority channel activity causes PRI to flash.
12-Button Keypad (W7 and W9) — The keypad is used to change the status of options and for
entering numbers. Several keys serve multiple functions. See the ASTRO Digital Spectra or
Digital Spectra Plus Users Guide for a complete description of keypad operation.

Chapter 2 Basic Maintenance
2.1 Introduction
This section of the manual describes preventive maintenance, handling precautions, and some basic
repair procedures and techniques. Each of these topics provides information vital to the successful
operation and maintenance of your radio.
2.2 Preventive Maintenance
Radios are shipped from the factory with a worst-case frequency error of ±200 Hz for VHF, ±300 Hz
for UHF, and ±500 Hz for 800 MHz. These specifications are tighter than the most stringent FCC-
required specifications of 2 ppm (parts per million) for both VHF and UHF, and 1.5 ppm for 800 kHz,
within which the radio will operate to specification.
2.2.1 Reference Oscillator
For radios that have been in storage for over six months from the factory ship date, the reference
oscillator should be checked when the radio is initially deployed to the field. It is strongly
recommended that the reference oscillator be checked every time the radio is serviced or at least
once a year, whichever comes first.
The crystal contained in the reference oscillator naturally drifts over time due to its aging
characteristic. Periodic (annual) adjustment of the reference oscillator is important for proper radio
operation.
Improper adjustment can result in both poor performance and interference with other users operating
on adjacent channels.
A recommended test setup and tuning procedure is detailed in Chapter 6. Radio Alignment
Procedure. The frequency counter used for this procedure must have a stability of 0.1 ppm or better.
2.2.2 Inspection
Check that the external surfaces of the radio are clean, and that all external controls and switches
are functional. A detailed inspection of the interior electronic circuitry is not needed.
2.2.3 Cleaning
The following procedures describe the recommended cleaning agents and the methods to be used
when cleaning the external and internal surfaces of the radio. External surfaces include the control
head and radio chassis. These surfaces should be cleaned whenever a periodic visual inspection
reveals the presence of smudges, grease, and/or grime. Internal surfaces should be cleaned only
when the radio is disassembled for servicing or repair.
The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild
dishwashing detergent in water. The only factory recommended liquid for cleaning the printed circuit
boards and their components is isopropyl alcohol (70% by volume).

2-2 Basic Maintenance: Handling Precautions
2.2.4 Cleaning External Plastic Surfaces
The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled
brush to work all loose dirt away from the radio. A soft, absorbent, lint-free cloth or tissue should be
used to remove the solution and dry the radio. Make sure that no water remains entrapped near the
connectors, cracks, or crevices.
2.2.5 Cleaning Internal Circuit Boards and Components
Isopropyl alcohol may be applied with a stiff, non-metallic, short-bristled brush to dislodge embedded
or caked materials located in hard-to-reach areas. The brush stroke should direct the dislodged
material out and away from the inside of the radio.
Alcohol is a high-wetting liquid and can carry contamination into unwanted places if an excessive
quantity is used. Make sure that controls or tunable components are not soaked with the liquid. Do
not use high-pressure air to hasten the drying process, since this could cause the liquid to puddle
and collect in unwanted places.
Upon completion of the cleaning process, use a soft, absorbent, lint-free cloth to dry the area. Do not
brush or apply any isopropyl alcohol to the frame, front cover, or back cover.
NOTE: Always use a fresh supply of alcohol and a clean container to prevent contamination by
dissolved material (from previous usage).
2.3 Handling Precautions
Complementary metal-oxide semiconductor (CMOS) devices, and other high-technology devices,
are used in this family of radios. While the attributes of these devices are many, their characteristics
make them susceptible to damage by electrostatic discharge (ESD) or high-voltage charges.
Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special
precautions must be taken to prevent device damage during disassembly, troubleshooting, and
repair. Handling precautions are mandatory for this radio, and are especially important in low-
humidity conditions. DO NOT attempt to disassemble the radio without observing the following
handling precautions:
Eliminate static generators (plastics, Styrofoam, etc.) in the work area.
Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back
loose-hanging neckties.
Store and transport all static-sensitive devices in ESD-protective containers.
Disconnect all power from the unit before ESD-sensitive components are removed or inserted
unless otherwise noted.
Use a static-safeguarded workstation, through the use of an anti-static kit (Motorola part
number 01-80386A82). This kit includes a wrist strap, two ground cords, a static-control table
mat and a static-control floor mat.
NOTE:Be sure that the table and floor mats are properly grounded.
When these items are not readily available, observing the following techniques will minimize the
chance of damage:
The effects of certain chemicals and their vapors can have
harmful results on certain plastics. Aerosol sprays, tuner
cleaners, and other chemicals should be avoided.

Basic Maintenance: Handling Precautions 2-3
If a static-sensitive device is to be temporarily set down, use a conductive surface for
placement of the device.
Make skin contact with a conductive work surface first and maintain this contact when the
device is set down or picked up.
Always wear a conductive wrist strap when servicing this equipment. The Motorola part number
for a replacement wrist strap that connects to the table mat is 42-80385A59.

2-4 Basic Maintenance: Handling Precautions
Chapter 3 Basic Theory of Operation
3.1 Introduction
The following theory will help isolate the problem to a particular board. Using circuit board
replacement as the basic service approach maximizes the working time of the radio.
3.2 General Overview
The ASTRO Digital Spectra and Digital Spectra Plus radios are wideband, synthesized, fixed-tuned
radios. The ASTRO Digital Spectra is available with VHF, UHF, and 800 MHz bands. The ASTRO
Digital Spectra Plus is available with VHF and 800 MHz bands only. All ASTRO Digital Spectra radios
are capable of both analog operation and ASTRO mode (digital) in 12.5 kHz, 20 kHz, 25 kHz, or 30
kHz bandwidths.
The ASTRO Digital Spectra and Digital Spectra Plus radios consist of seven major assemblies, six of
which are in the main radio chassis. They are:
Control Head Assembly (Dash- or Remote-Mount) — is connected, directly or remotely, to the
front of the transceiver by the interconnect board or remote interconnect board and control
cable. This assembly contains a vacuum fluorescent (VF) display, VF driver, microprocessor
and serial bus interface.
Power Amplifier (PA) — contains antenna switch, directional coupler/detector, and amplifier(s).
Front-End Receiver Assembly — contains pre-amplifier, preselector, mixer, and injection filter.
Radio-Frequency (RF) Board — contains receiver IF amplifier, demodulator, synthesizer logic
and filtering circuitry, and digital receiver back-end integrated circuit (IC).
VCO/Buffer/Divider Board — contains voltage-controlled oscillator (VCO), divider, receive and
transmit buffers.
Command Board — contains power control/regulator, digital-to-analog (D/A) IC, serial bus inter-
face, and audio power amplifier (PA).
VOCON (Vocoder/Controller) Board (Digital Spectra radio) — contains the microcomputer unit
(MCU), its associated memory and memory management integrated circuit, and the digital-sig-
nal processor (DSP) and its associated memories and support IC.
For the ASTRO Digital Spectra Plus radio, the VOCON board architecture is based on a Dual-Core
processor, which contains a DSP Core, an MCORE 210 Microcontroller Core, and custom
peripherals. The board also contains memory ICs and DSP-support ICs.
February 3, 2003 6881076C20-E
3-2 Basic Theory of Operation: Analog Mode of Operation
3.3 Analog Mode of Operation
3.3.1 Receive Operation
When the radio is receiving, the signal comes from the antenna/antenna-switch on the power
amplifier board to the front-end receiver assembly. The signal is then filtered, amplified, and mixed
with the first local-oscillator signal generated by the voltage-controlled oscillator (VCO). The resulting
intermediate frequency (IF) signal is fed to the IF circuitry on the RF board, where it is again filtered
and amplified. This amplified signal is passed to the digital back-end IC, where it is mixed with the
second local oscillator to create the second IF at 450 kHz. The analog IF is processed by an analog-
to-digital (A/D) converter, where it is converted to a digital bit stream and divided down to a baseband
signal, producing digital samples. These samples are converted to current signals and sent to the
digital-signal processor (DSP)-support IC. The DSP-support IC digitally filters and discriminates the
signal, and passes it to the DSP. The DSP decodes the information in the signal and identifies the
appropriate destination for it. For a voice signal, the DSP routes the digital voice data to the DSP-
support IC for conversion to an analog signal. The DSP-support IC then presents the signal to the
audio power amplifier on the command board, which drives the speaker. For signaling information,
the DSP decodes the message and passes it to the microcomputer.
3.3.2 Transmit Operation
When the radio is transmitting, microphone audio is passed to the command board limiter, then to
the DSP-support IC where the signal is digitized. The DSP-support IC passes digital data to the DSP
where pre-emphasis and low-pass (splatter) filtering are done. The DSP returns this signal to the
DSP-support IC where it is reconverted into an analog signal and scaled for application to the
voltage-controlled oscillator as a modulation signal. Transmitted signaling information is accepted by
the DSP from the microcomputer, coded appropriately, and passed to the DSP-support IC, which
handles it the same as a voice signal. Modulation information is passed to the synthesizer along the
modulation line. A modulated carrier is provided to the power amplifier (PA) board, which transmits
the signal under dynamic power control.
3.4 ASTRO Mode of Operation
In the ASTRO mode (digital mode) of operation, the transmitted or received signal is limited to a
discrete set of deviation levels, instead of continuously varying. The receiver handles an ASTRO-
mode signal identically to an analog-mode signal up to the point where the DSP decodes the
received data.
In the ASTRO receive mode, the DSP uses a specifically defined algorithm to recover information.
In the ASTRO transmit mode, microphone audio is processed the same as an analog mode with the
exception of the algorithm the DSP uses to encode the information. This algorithm will result in
deviation levels that are limited to discrete levels.
3.5 Control Head Assembly
3.5.1 Display (W4, W5, and W7 Models)
The control head assembly for W4, W5, and W7 models has an 8-character, alphanumeric, vacuum
fluorescent display. The anodes and the grids operate at approximately 34 Vdc when on and 0 Vdc
when off. The filament operates at approximately 24 Vrms. The voltage for the display is generated
by a fixed-frequency, variable duty-cycle controlled “flyback” voltage converter. The switching
frequency is approximately 210 kHz. The internal microprocessor controls the voltage converter,
which provides approximately 3.7 Vdc to the vacuum fluorescent (VF) driver and approximately 2.4
Vrms to the VF display.
6881076C20-E February 3, 2003
Basic Theory of Operation: Control Head Assembly 3-3
3.5.2 Display (W9 Model)
The control head assembly for a W9 model has an 11-character, alphanumeric, vacuum fluorescent
display. It needs three separate voltages to operate: the cathode needs 35V to accelerate electrons
to the anode; the grid needs 40V to totally shut off current flow; the filament needs 3.8 Vrms at 80
mA. These voltages are obtained from the transformer on the display controller board.
3.5.3 Vacuum Fluorescent (VF) Display Driver
This VF display driver receives ASCII data from the VOCON board, decodes it into display data, and
then scans the display with the data. Once properly loaded into the display, data is refreshed without
any further processor action. The display driver is periodically reset by the actions of transistors that
watch the clock line from the microprocessor to the display driver. When the clock line is held low for
more than 600 milliseconds, the display driver resets and new display data follows.
3.5.4 Vacuum Fluorescent (VF) Voltage Source (W9 Model)
Voltage for the VF display is generated by a fixed frequency, variable-duty cycle driven, flyback
voltage converter. An emitter-coupled astable multivibrator runs at approximately 150 kHz. The
square wave output from this circuit is integrated to form a triangle that is applied to the non-inverting
input of half an integrated circuit (IC).
During start up, the inverting input is biased at 3.7V. A transistor is on while the non-inverting input
voltage is below 3.7V. This allows current to flow in a transformer, building a magnetic field. When
the triangle wave exceeds 3.7V, the transistor turns off and the magnetic field collapses, inducing
negative current in the transformer.
This current flow charges two capacitors. As the voltage on one of the capacitors increases beyond
35V, a diode begins to conduct, pulling the integrated circuit’s inverting input below 3.7V. This
decreases the cycle time to produce the 35V. The 41V supply is not regulated, but it tracks the 35V
supply.
Similarly, the ac supply for VF filament is not regulated, but is controlled to within one volt by an
inductor on the display board.
3.5.5 Controls and Indicators
The control head assembly processes all the keypad (button) inputs and visual indicators through
the microprocessor. Some of the buttons double as function keys for radio options. All buttons are
backlit to allow operation in low light. Refer to Chapter 1. Introduction (page 1-3 and page 1-5) for a
functional description of each control switch, button, or indicator.
3.5.6 Status LEDs
These LEDs are driven by the display driver as though they were decimal points on the VF display.
Level shifting transistors are required for this since the display driver uses 39 Vdc for control signals.
3.5.7 Backlight LEDs
The microprocessor operates the backlight LEDs. A transistor supplies base current to the individual
LED driver transistors. The driver transistors act as constant current sources to the LEDs. Some
backlight LEDs are connected to a thermistor. This circuit allows more current to flow through these
LEDs at room temperature and reduces current as the temperature rises.
February 3, 2003 6881076C20-E
3-4 Basic Theory of Operation: Power Amplifier
3.5.8 Vehicle Interface Port (VIP)
3.5.8.1 Remote-Mount
The VIPs allow the control head to operate outside circuits and to receive inputs from outside the
control head. There are three VIP outputs that are used for relay control. There are also three VIP
inputs that accept inputs from switches. See the cable kit section for typical connections of VIP input
switches and VIP output relays.
The VIP output pins are located on the back of the control head below the area labeled “VIP.” These
connections are used to control relays. One end of the relay should be connected to switched B+,
while the other side is connected to a software-controlled on/off switch inside the control head. The
relay can be normally on or normally off depending on how the VIP outputs are configured. The
function of these VIP outputs can be defined by field programming the radio. Typical applications for
VIP outputs are external horn/lights alarm and horn ring transfer relay control.
3.5.8.2 Dash-Mount
The VIP outputs are driven by a serial-to-parallel shift register. The output transistors are capable of
sourcing 300mA current. Primarily, these transistors control external relays. The relay is connected
between the collector and switched B+.
Each VIP input transistor is connected to a dedicated input port through transistors used for input
protection. These VIP inputs are connected to ground with either normally open or normally closed
switches.
3.5.9 Power Supplies
The +5V supply is a three-terminal regulator IC to regulate the 12V SWB+ down for the digital logic
hardware.
3.5.10 Ignition Sense Circuits
A transistor senses the vehicle ignition’s state, disabling the radio when the ignition is off. For
negative-ground systems, the orange lead is typically connected to the fuse box (+12V).
3.6 Power Amplifier
The power amplifier (PA) is a multi-stage, discrete-transistor RF amplifier consisting of the following:
Low-level power controlling stage
•Drivers
Final amplifier
Directional coupler
Antenna switch
Harmonic filter
3.6.1 Gain Stages
The first stage buffers the RF signal, filters harmonics, and acts as a variable amplifier. All of the
amplifying stages are matched using transmission lines, capacitors, and inductors and are supplied
with dc from either A+, keyed 9.4V, or 9.6V sources. Following the last gain stage, PIN diodes switch
the signal flow either from the antenna to the receiver, or from the last gain stage to the antenna.
6881076C20-E February 3, 2003
Basic Theory of Operation: Front-End Receiver Assembly 3-5
3.6.2 Power Control
A directional coupler and detector network controls power. It senses the forward power from the last
gain stage and feeds the detected voltage back to the command board control circuitry, where it is
compared to a reference voltage set during power-set procedures. The dc feed voltage is corrected
and supplied to the “controlled” stage of the power amplifier. Circuitry on the power amplifier board
controls the gain of the first stage and is proportional to the dc control voltage.
3.6.3 Circuit Protection
Current and temperature sensing circuitry on the power amplifier board feed sensed voltages to the
command board for comparison. If the command board suspects a fault condition, it overrides the
power control function and cuts the power back to a level that is safe for the conditions.
3.6.4 DC Interconnect
The ribbon cable connector carries sensed voltages for power and protection to the command board.
It also carries A+ feed to the command board for distribution throughout the internal transceiver
chassis and carries control voltage from the command board to the power amplifier board.
The rear battery connector carries A+ from the battery to the power amplifier board. The red lead
goes directly to the A+ terminal on the PA board. The black lead from the battery connector ties to
the chassis, and connection to the power amplifier board is made through the board mounting
screws.
A+ ground connection for the internal transceiver chassis is through the RF coax ground connectors
and through the mechanical connection of the power amplifier heatsink to the rest of the radio.
During test conditions in which the power amplifier assembly (board and heatsink) is physically
disconnected from the rest of the radio, it is acceptable to rely on the coax cable connections to carry
ground to the internal chassis.
3.7 Front-End Receiver Assembly
The receiver front-end consists of a preselector, a mixer circuit, and an injection filter. The receiver
injection (1st local oscillator) comes from the VCO assembly through a coax cable. The injection filter
is either fixed-tuned or tuned at the factory depending upon the bandsplit. The output of the filter is
connected to the mixer.
The preselector is a fixed-tuned filter. The receiver signal is fed to the preselector from the antenna
switch in the PA for the 800 MHz radios, or the preamp output for VHF and UHF. The signal is then
sent to the mixer integrated circuit where it is connected to the mixer transistor. The receiver injection
is also fed to this point. The mixer output is at the 1st IF center frequency of 109.65MHz. This signal
is sent to the 1st IF on the RF board through a coaxial cable.
3.8 Radio Frequency (RF) Board
The RF board contains the common synthesizer circuits and dual IF receiver and demodulation
circuits. A 4-pole crystal filter at 109.65MHz provides first IF selectivity. For HRN6014D, HRN6020C,
HRN6019C, HRN4009D, HRN4010C, and later RF board kits, two 2-pole crystal filters provide first
IF selectivity at 109.65MHz. The output of the filter circuit is fed directly to the custom digital back-
end circuit module. An amplifier (at 109.65MHz), the second mixer, the second IF amplifiers (at 450
kHz), the IF digital-to-analog converter, and the baseband down-converter are part of the digital
backend circuit module. The digital backend circuit module also converts a 2.1MHz reference to a
2.4MHz clock for the DSP support circuit module.
February 3, 2003 6881076C20-E
3-6 Basic Theory of Operation: Voltage-Controlled Oscillator (VCO)
Synthesizing for the first and second VCO is performed by the prescaler and synthesizer ICs. These
ICs are programmed through a serial data bus from signals generated on the VOCON board. A dc
voltage, generated on the command board, sets the synthesizer’s reference oscillator frequency of
16.8MHz. This voltage is controlled by the digital-to-analog converter (D/A), and is the only element
of the RF board requiring alignment.
The second local oscillator runs at 109.2MHz (low-side injection), and consists of a VCO that is
frequency-locked to the reference oscillator. Part of the local oscillator’s circuitry is in the prescaler
IC.
A clamp and rectifier circuit on the RF board generates a negative dc voltage of 4 volts (nominal) for
increasing the total voltage available to the first VCO and second local oscillators VCO. The circuit
receives a 300 kHz square wave output from the prescaler IC, then clamps, rectifies, and filters the
signal for use as the negative steering line for the two VCOs.
3.9 Voltage-Controlled Oscillator (VCO)
3.9.1 VHF Radios
The voltage-controlled oscillator (VCO) assembly utilizes a common-gate FET in a Colpitts
configuration as the gain device. The LC tank circuit’s capacitive portion consists of a varactor bank
and a laser-trimmed stub capacitor. The inductive portion consists of microstrip transmission line
resonators. The stub capacitor serves to tune out build variations. Tuning is performed at the factory
and is not field adjustable. The varactor network changes the oscillator frequency when the dc
voltage of the steering line changes. The microstrip transmission lines are shifted in and out of the
tank by PIN diodes for coarse frequency jumps. A third varactor is used in a modulation circuit to
modulate the oscillator during transmit.
The VCO output is coupled to a transistor for amplification and for impedance buffering. The output
of this stage passes through a low-pass filter where the signal is split into three paths. One path
feeds back to the synthesizer prescaler; the other two provide injection for the RX and TX
amplification strings. The receive injection signal is further amplified and passed to the RX front-end
injection filter. The transmit signal goes to an ECL divider, which divides the signal by two. The signal
is amplified and buffered and then injected into the transmitter’s low-level amplifier.
A 5V regulator provides power to the divider. All transmit circuitry operates from keyed 9.4 volts to
conserve current drain while the radio is receiving. A transistor/resistor network drives the PIN
diodes in the VCO tank. These driver networks provide forward bias current to turn diodes on and
reverse the bias voltage to turn the diodes off. AUX 1 AND AUX 2 lines control the PIN diode driver
networks.
3.9.2 UHF and 800 MHz Radios
The VCO assembly generates variable frequency output signals controlled by the two steering lines.
The negative steering line increases the tuning range of the VCO, while the positive steering line
affects the synthesizer control loop to incrementally change the frequency.
The VCO generates a signal in the required frequency range. For UHF and 800 MHz radios, this
signal is fed to the doubler/buffer circuit which, in turn, doubles the VCO output frequency and
amplifies it to the power level required by the TX buffer and RX mixer. A PIN diode switch routes the
signal to the TX port when the keyed 9.4V is high. Otherwise, the signal is routed to the RX port. The
VCO assembly’s synthesizer feedback output is the same as the doubler output frequency.
3.10 Command Board
The serial input/output IC provides command board functions including buffers for PTT, channel
active, squelch mute, busy, and data transmission, and logic functions for switched B+, emergency,
reset, and power control.
6881076C20-E February 3, 2003
Basic Theory of Operation: VOCON (Vocoder/Controller) Board 3-7
The regulator and power control circuits include an unswitched +5V discrete circuit and the regulator/
power control IC, which produces both switched +5V and 9.6V. The unswitched +5V source is used
as a reference for its switched +5V source. Filtered unswitched +5V is used for the microcontrol
circuits. Switched +5V and 9.6V are controlled by a digital transistor from the serial input/output IC.
The power control circuitry receives power set and limit inputs from the digital-to-analog IC, and
feedback from the RF power amplifier. Based on those inputs, the power control circuitry produces a
control voltage to maintain a constant RF power level to the antenna.
The reset circuits consist of the power-on reset, high/low battery voltage reset, and the external bus
system reset. The reset circuits allow the microcomputer to recover from an unstable situation; for
example, no battery on the radio, battery voltage too high or too low, and remote devices on the
external bus not communicating. Communication in RS-232 protocol is provided by an IC which
interfaces to the rear accessory connector (J2).
3.11 VOCON (Vocoder/Controller) Board
The VOCON board, located on the top side of the radio chassis, contains a microcontrol unit (MCU)
with its flash memory, DSP, and DSP-support ICs. The VOCON board controls receive/transmit
frequencies, the display, and various radio functions, using either direct logic control or serial
communication to external devices. The connector J801 provides interface between the encryption
module and the VOCON board for encrypting voice messages.
3.11.1 ASTRO Digital Spectra
The VOCON board executes a stored program located in the FLASH ROM. Data is transferred to
and from memory by the microcontrol unit data bus. The memory location from which data is read, or
to which data is written, is selected by the address lines.
The support-logic IC acts as an extension of the microcontrol unit by providing logic functions such
as lower address latch, reset, memory address decoding, and additional control lines for the radio.
The VOCON board controls a crystal-pull circuit to adjust the crystal oscillator frequency on the
microcontrol unit, so that the E-clock harmonics do not cause interference with the receive channel.
The vocoder circuitry on the VOCON board is powered by a switched +5 volt regulator located on the
command board. This voltage is removed from the board when the radio is turned off by the control
head switch.
The DSP IC performs signaling, voice encoding/decoding, audio filtering, and volume control
functions. This IC performs Private-Line/Digital Private-Line (PL/DPL) encode and alert-tone
generation. The DSP IC transmits pre-emphasize analog signals and applies a low-pass (splatter)
filter to all transmitted signals. It requires a 33MHz crystal to function. An 8 kHz interrupt signal
generated by the DSP-support IC is also required for functionality. This device is programmed using
parallel programming from the microcontrol unit and the DSP-support IC.
The DSP-support IC performs analog-to-digital and digital-to-analog conversions on audio signals. It
contains attenuators for volume, squelch, deviation, and compensation, and it executes receiver
filtering and discrimination. The IC requires a 2.4MHz clock to function (generated by the digital
back-end IC) and is programmed by the microcontrol unit’s SPI bus.
3.11.2 ASTRO Digital Spectra Plus
The VOCON board, located on the top-side of the chassis, contains a Dual-Core processor, which, in
turn, contains a DSP Core, an MCORE Microcontroller Core, and custom peripherals. The board
also contains memory ICs and DSP support ICs.
February 3, 2003 6881076C20-E
3-8 Basic Theory of Operation: VOCON (Vocoder/Controller) Board
The VOCON board controls receive/transmit frequencies, the display, and various radio functions,
using either direct logic control or serial communication to external devices. The connector J801
provides an interface between the encryption module and the VOCON board for encrypting voice
messages.
The VOCON board executes a stored program located in the FLASH ROM. Data is transferred to
and from memory by the microcontroller unit data bus. The memory location from which data is read,
or to which data is written, is selected by the address lines.
The vocoder circuitry on the VOCON board is powered by two regulated voltage supplies: 3.0 Vdc
and 1.8 Vdc. These regulated supplies are powered by a switched 5 Vdc regulator located on the
command board. This 5 Vdc supply also powers some vocoder circuitry. This voltage is removed
from the board when the radio is turned off by the control head switch.
The DSP Core inside the Dual-Core processor performs signaling, voice encoding/decoding, audio
filtering, and volume control functions. This core performs Private-Line/Digital Private-Line (PL/DPL)
encode and alert-tone generation. The DSP Core transmits pre-emphasized analog signals and
applies a low-pass (splatter) filter to all transmitted signals. The Dual-Core processor requires a
16.8MHz and a 32 kHz clock to function.
The DSP-support ICs perform analog-to-digital and digital-to-analog conversions on audio signals.
They contain attenuators for volume, squelch, deviation, and compensation. The receiver interface
IC requires a 2.4MHz clock to function (generated by the digital back-end IC) and is programmed by
the microcontroller unit’s SPI bus.

Figure 6-2. RSS Service Menu Layout
All SERVICE screens read and program the radio codeplug directly; you do NOT have to use the
RSS GET/SAVE functions to use the SERVICE menus.
6.2.2 Softpot
The SERVICE screens introduce the concept of the softpot, an analog SOFTware-controlled
POTentiometer used for adjusting all transceiver alignment controls.
Each SERVICE screen provides the capability to increase or decrease the softpot value with the
keyboard UP/DOWN arrow keys respectively. A graphical scale is displayed indicating the minimum,
maximum, and proposed value of the softpot, as shown in Figure 6-3.
Figure 6-3. Softpot Concept
Adjusting the softpot value sends information to the radio to increase (or decrease) dc voltage in the
corresponding circuit. For example, pressing the UP arrow key at the Reference Oscillator screen
instructs the radio’s microcomputer to increase the voltage across a varactor in the reference
oscillator, which increases the frequency.
In ALL cases, the softpot value is just a relative number corresponding to a digital-to-analog (D/A)
generated voltage in the radio.
Perform the following alignment procedures in the sequence indicated.
NOTE: Some of the following screens may vary depending upon the radio under test and the version
of radio service software you are using. Refer to your radio service software user’s guide.

Radio Alignment Procedure: RSS 6-3
6.2.3 Reference Oscillator Alignment
Radios are shipped from the factory with a worst-case frequency error of ±200 Hz for VHF, ±300 Hz
for UHF, and ±500 Hz for 800 MHz. These specifications are tighter than the more stringent FCC
requirement of 1.5 ppm for all bands.
For radios that have been in storage for over six months from the factory ship date, the reference
oscillator should be checked when the radio is initially deployed to the field. It is strongly
recommended that the reference oscillator be checked every time the radio is serviced or at least
once a year, whichever comes first.
The crystal contained in the reference oscillator naturally drifts over time due to its aging
characteristic. Periodic (annual) adjustment of the reference oscillator is important for proper radio
operation.
Improper adjustment can result in both poor performance and interference with other users operating
on adjacent channels.
This test can be done with either the R-2670 Communication Analyzer or the 8901_ Modulation
Analyzer.
1. Initial set up using the R-2670 Communication Analyzer:
- RF Control: MONITOR
- B/W: WB
- Freq: RSS frequency under test
- Attenuation: 20dB
- Mon RF in: RF I/O
- Meter: RF Display
- Mode: STD
- Input Level: uV or W
- Display: Bar Graphs
- Squelch: Mid-range or adjust as necessary
2. Initial set up using the 8901_ Series Modulation Analyzer:
- Press the green Automatic Operation button on the analyzer.
- Press the FREQ key.
- Type 7.1 followed by the SPCL button to set the 8901_ modulation analyzer for maximum
accuracy.
3. Read the radio using the RSS.
4. From the SERVICE MENU, press F2 to select the TRANSMITTER ALIGNMENT MENU.
5. Press F2 again to select the REFERENCE OSCILLATOR alignment screen (Figure 6-4).

6. If you are using the R-2670 Communication Analyzer, enter the frequency displayed on the
RSS screen in the “RF control” section of the R-2670. Under the “Meter” section of the
display, choose RF DISPLAY.
7. Press F6 to key the radio. The screen will indicate that the radio is transmitting.
8. Wait 5 seconds until the analyzer reading settles. Record the transmitter frequency (or note
the frequency error reading on the screen).
9. Use the Up and Down arrow keys on your computer keyboard to adjust the reference
oscillator softpot value. Allow approximately five seconds for the analyzer frequency reading
to stabilize after each change.
10. Adjust the frequency error, as indicated in Table 6-1.
11. Press F6 again to dekey the radio.
12. Press F8 to program the new softpot value.

6.2.6 Transmit Deviation Balance (Compensation) Alignment
NOTE: Compensation alignment is only required after replacing (or servicing) the command board,
VOCON (vocoder/controller) board, RF board, or the VCO board.
Compensation alignment balances the modulation sensitivity of the VCO and reference modulation
(synthesizer low-frequency port) lines. The compensation algorithm is critical to the operation of
signaling schemes that have very-low-frequency components (for example, DPL) and could result in
distorted waveforms if improperly adjusted.
Compensation values are adjusted at the different test frequencies to achieve a flat VCO modulation
sensitivity with respect to the RF frequency and with respect to the low frequency response of the
synthesizer.
This test can be done with either the R-2670 Communication Analyzer or the 8901_ Series
Modulation Analyzer. The R-2670 analyzer is recommended.
1. Initial set up using the R-2670 Communication Analyzer:
- Connect a BNC cable between the “DEMOD OUT” port and the “VERT/SINAD DIST/DMM
COUNTER IN” port on the R-2670.
-Press the SPF key on the R-2670 to display the “SPECIAL FUNCTIONS MENU.” Move the
cursor to “High Pass,”and select 5 Hz via the soft key menu. Select 20 kHz for the “Low
Pass” setting.
- In the “RF Control” section of the R-2670, enter the frequency displayed on the RSS screen
(choose a test frequency from the list of frequencies displayed under Transmit Deviation
Balance [Compensation] in RSS). Move the cursor to the “B/W” setting and select “WIDE
+/- 100 kHz” via the soft key menu.
- Place the R-2670 cursor in the “Display” zone. Select “AC VOLTS” on the soft key menu.
Move the cursor to the “Range” setting and select “AUTO.”
2. Initial set up using the 8901_ Series Modulation Analyzer:
- Press the FM MEASUREMENT button. (The “Error 03-input level too low” indication is
normal until an input signal is applied.)

6.2.8 Bit Error Rate (BER) Performance Check
This check tests the Bit Error Rate (BER) of the radio’s receiver at a desired frequency.
Required equipment and software: R-2670 system analyzer, with P25 option; IBM PC-compatible
computer, RSS
In Generate mode, the R-2670 system analyzer modulates the RF carrier with a 1011Hz tone test
pattern to test the Unit Under Test (UUT) receiver. The test pattern received by the UUT is compared
in the UUT with a stored version of the test pattern to compute a BER.
1. Connect the RF Input port of the UUT to the RF IN/OUT port of the analyzer.
2. Set up the R-2670 as follows:
- Place the cursor in the RF Zone, and configure the analyzer as follows:
RF control: Generate
Preset: B/W: NB
Freq: Desired test frequency; for example, 851.0625MHz
Output Level: -50.0 dBm
Gen RF Out: RF I/O
- Place the cursor on the Mode field in the Display Zone.
- Select PROJECT 25 STD.
- Set the METER field to RF DISPLAY.
- Place the cursor on the CODE field in the Audio Zone.
- Select the 1011 Hz PAT softkey.
This generates a 1011Hz tone test pattern. If this pattern is received correctly by the UUT,
the measured BER should be zero.
- Set the deviation in the Audio Zone as PROJ25Dev: 2.83 kHz ~.
3. Using the RSS, configure the UUT as follows:
- In the RSS Main Menu, press F2 to select SERVICE: Alignment.
-Press F5 to select Performance Testing.
-Press F2 to select Bit Error Rate.
- Enter the desired test frequency in the Rx Frequency (MHz) field; for example,
851.0625MHz.
- Set the Modulation Type to 12.5 kHz/C4FM.
- Set the BER Integration Time (sec) to not less than 7.200.
-Press F6 (Start/Stop) to begin the test.
4. Monitor the radio’s received BER (%) results on the computer.
5. Reduce the analyzer output level to achieve a standard Bit Error Rate of 5%. The analyzer
RF output level should be within the SINAD specification of the UUT.
6.3 ASTRO Digital Spectra and Digital Spectra Plus Tuner Software
A personal computer (PC) and Tuner Software are required to align the radio. Please refer to the
CPS Programming Installation Guide (Motorola part number 6881095C44) for installation and setup
procedures for the software. To perform the alignment procedures, the radio must be connected to
the computer and to a universal test set, as shown in the following figure.

6.3.3 Transmit Power Alignment
Transmit Power alignment is required after replacing (or servicing) the transceiver board.
This alignment procedure adjusts the transmit power of the radio and must be performed for two
different power levels, at multiple frequencies for each power level, to allow for proper alignment
across the entire RF band. The RF band is divided into frequency zones with a calibration point
(value) in each zone.
Notes
The same softpot attenuation value will result in DIFFERENT radio output power levels at
different frequencies.
All power measurements are to be made at the antenna port.
1. Select the TX Power (High, Mid, or Low) alignment screen. The screen will indicate the
transmit frequencies to be used. See Figure 6-14.

6.3.5 Transmit Deviation Balance (Compensation) Alignment
This alignment is required after replacing (or servicing) the VOCON board or the transceiver board.
This alignment procedure balances the modulation contributions of the low- and high-frequency
portions of a baseband signal. Proper alignment is critical to the operation of signaling schemes that
have very low frequency components (for example, DPL) and could result in distorted waveforms if
improperly adjusted.
6881076C20-E February 3, 2003
Radio Alignment Procedure: ASTRO Digital Spectra and Digital Spectra Plus Tuner Software 6-19
This procedure needs to be performed at multiple frequencies to allow for proper alignment across
the entire RF band. The RF band is divided into frequency zones with a calibration point (value) in
each zone.
Proper alignment requires a modulation analyzer or meter with a frequency response to less than
10Hz modulating frequency. The modulation analyzer settings during this test should be set for
average deviation, a 15 kHz low-pass filter, no de-emphasis, and no high-pass filter, if these settings
are supported.
This test can be done with either the R-2670 Communication Analyzer or the 8901_ Series
Modulation Analyzer. The method of choice is the R-2670 analyzer.
1. Initial set up using the R-2670 Communication Analyzer:

7-2 Encryption: Load an Encryption Key
The secure status annunciator not lit (OFF) indicates that the transmitted signal is non-
encrypted.
Whether the current personality is strapped for secure or clear, the secure status annunciator
correctly displays the transmit operation as being either secure (encrypted) or clear (non-encrypted).
NOTE: You cannot change from secure to clear while the PTT button is pressed. The radio will
generate an illegal tone and the transmission will be terminated.
Secure-equipped radios automatically determine whether a secure or clear voice message is being
received. This allows you to receive either type of message without having to reset the
programmable secure button.
7.1.4 Secure Emergency Operation
Clear or secure emergency-call operation is determined by the programming of the selected mode
(or talkgroup) or the default emergency mode, if set up. Otherwise, transmit operation is controlled
by the setting of the secure, programmable button. You will not be able to change from secure to
clear, or from clear to secure, operation during an emergency call.
7.2 Load an Encryption Key
7.2.1 Model W3
To load an encryption key into a Model W3 radio:
1. Ensure that an encryption module is installed in the radio.
2. Load an encryption key into the radio’s memory from a key-

encryption type.
To load the key, attach the keyloader cable to the front of the
radio. (Refer to the KVL instruction manual for loading.)
3. KEYLOADING is
displayed on your
radio while the key
transfer is in progress.
For single-key radios, a short tone sounds when a key is
successfully loaded.
For multikey radios, an alternating tone sounds for a few
seconds after keys are successfully loaded.
NOTE:An invalid encryption key aborts a secure
transmission. KEYFAIL is displayed and a keyfail tone
(consecutive medium-pitched beeps) sounds until
you release the PTT button.
4. If a mode is not programmed for either secure or clear-only
operation, use the secure programmable button to select
secure or clear transmission.
NOTE:You cannot change from secure to clear, or from clear
to secure, while pressing the PTT button.

7-10 Encryption: Advanced Secure Operation
7.7 Advanced Secure Operation
NOTE: The Advanced Secure feature is available only on radios that have been equipped by the
factory to support it. The radio must also be equipped with an encryption module.
Advanced Secure incorporates the Multikey feature and a dual-encryption feature into the existing
secure system. Multikey allows a radio to be equipped with multiple encryption keys. A default key is
included and is associated with the current mode. The keys are strapped to a given mode or are
operator-selectable and can be indexed into groups of keys (for example, 16 keys can be indexed
into two groups of eight keys). The keys are loaded using a manual keyloader.
In addition, your radio can support up to eight different encryption algorithms simultaneously.
7.7.1 Multikey Operation
The multikey feature can be used in both conventional and trunked applications.
Conventional Multikey - The encryption keys can be selectively strapped, one per each chan-
nel, by a qualified radio technician. In addition, you can have operator-selectable keys, opera-
tor-selectable indices, and operator-selectable key erasure. Encryption keys are loaded into the
radio through a KVL.
Trunked Multikey - If you use your radio for both conventional and trunked applications, the
encryption keys have to be strapped for trunking on a per talkgroup, or announcement group,
basis. In addition, a different encryption key can be strapped to other features such as private
call, dynamic regrouping, failsoft, interconnect, system wide, or emergency talkgroup.
5. One of the following occurs:
If the radio receives an acknowledgment from the dispatcher,
five tones sound.
If the radio does not receive an acknowledgment from the
dispatcher, the display shows NO ACK.
After the radio is rekeyed, it displays REKEYED and returns to
dispatch mode.
If the dispatcher does not allow it to be rekeyed, the radio
displays DENIED and returns to dispatch mode after three
seconds.
6. Press to exit and return to normal operation.
Chapter 8 Disassembly/Reassembly Procedures
8.1 Introduction
This section details the procedures necessary to remove and replace the printed circuit boards in the
ASTRO Digital Spectra and Digital Spectra Plus radios. After troubleshooting and determining which
board needs to be replaced, disconnect the test equipment, the antenna cable, and unhook the dc
power.
Locate the exploded view drawing of the radio in Chapter 11: Exploded Views and Parts Lists. Keep
it handy for reference when disassembling and reassembling the radio.
When installing a new circuit board, all mounting screws should be started before any are torqued.
This helps assure proper board alignment with the chassis.
After installing a new board, refer to Table 8-1 and perform the alignment procedures indicated for
the replaced board.
8.2 Replacement Procedures
NOTE: After performing alignment procedures, always exit the SERVICE menu entirely (to the MAIN
MENU) to save all changes properly. Failure to do so can result in a alignment (or other)
failure.
Disconnect all dc power to the radio before removing any
boards from the radio. Failure to remove power can result
in unit damage caused by transients or accidental shorts,
as well as a shock hazard.

Chapter 9 Basic Troubleshooting
9.1 Introduction
This section of the manual contains troubleshooting charts, error codes, a functional block diagram,
interconnect diagrams, and flexible circuit information. This section can help you isolate a problem to
the board level. Board-level troubleshooting does not attempt to isolate problems to the component
level. Component-level service information can be found in the ASTRO Digital Spectra and Digital
Spectra Plus Mobile Radios Detailed Service Manual. (Refer to the “Related Publications” section of
this manual on page xii for the specific manual number.)
NOTE: To access the various connector pins, use the housing eliminator/test fixture along with the
diagrams found in this section of the manual. (Refer to the section, “Service Aids and
Recommended Tools,” on page 4-2 for the appropriate Motorola service aids and tools parts
numbers.)
9.2 Replacement Board Procedures
Once a problem has been isolated to a specific board, use one of the following recommended repair
procedures:
Install a good board from your inventory into the radio.
Order a replacement board from Customer Care and Services Division at 1-800-422-4210.
Troubleshoot the defective board using the ASTRO Digital Spectra and Digital Spectra Plus
Mobile Radios Detailed Service Manual. (Refer to the “Related Publications” section of this
manual on page xii for the specific manual number.)
9.3 Power-Up Error Codes
When the radio is turned on (power-up), the radio performs cursory tests to determine if its basic
electronics and software are in working order. Problems detected during these tests are presented
as error codes on the radio’s display. The presence of an error should prompt the user that a
problem exists and that a service technician should be contacted.
Self-test errors are classified as either fatal or non-fatal. Fatal errors inhibit user operation; non-fatal
errors do not. Use the following tables to aid in understanding particular power-up error code
displays.
