Chapter 1 Maintenance
1.0
Introduction
This chapter of the manual describes:
•
Preventive maintenance
•
Safe handling of CMOS devices
•
Repair procedures and techniques
NOTE
1.1
The Servicing of your Intrinsically Safe Radios.
In order to maintain compliance, radios that are FM Approved to intrinsically safe
standards MUST be repaired at FM audited service centers. See Further Assistance From
Motorola on page 1-2 for more information.
Preventive Maintenance
Periodic visual inspection and cleaning is recommended.
1.2
Inspection
Check that the external surfaces of the radio are clean, and that all external controls and switches
are functional. It is not recommended to inspect the interior electronic circuitry.
1.3
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
front cover, housing assembly, and battery case. These surfaces should be cleaned whenever a
periodic visual inspection reveals the presence of smudges, grease, and/or grime.
NOTE
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 (100% by volume).
CAUTION: 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.
1.
Cleaning External Plastic Surfaces
The detergent-water solution should be applied sparingly with a stiff, non-metallic, shortbristled brush to work all loose dirt away from the radio. A soft, absorbent, lintless 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.

Introduction
2.
NOTE
1.4
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. Make sure that
controls or tunable components are not soaked with alcohol. Do not use high-pressure
air to hasten the drying process since this could cause the liquid to collect in unwanted
places. Upon completion of the cleaning process, use a soft, absorbent, lintless cloth to
dry the area. Do not brush or apply any isopropyl alcohol to the frame, front cover, or
back cover.
Always use a fresh supply of alcohol and a clean container to prevent contamination by
dissolved material (from previous usage).
Safe Handling of CMOS and LDMOS
Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios.
CMOS characteristics make them susceptible to damage by electrostatic 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 CMOS circuits and are especially important in low
humidity conditions. DO NOT attempt to disassemble the radio without first referring to the CMOS
CAUTION paragraph in the Disassembly and Reassembly section of the manual.

Parts Replacement and Substitution
When damaged parts are replaced, identical parts should be used. If the identical replacement
component is not locally available, check the parts list for the proper Motorola part number and
order the component from the nearest Motorola Communications parts center listed in the “Piece
Parts” section of this manual.
Rigid Circuit Boards
The family of radios uses bonded, multi-layer, printed circuit boards. Since the inner layers are
not accessible, some special considerations are required when soldering and unsoldering
components. The through-plated holes may interconnect multiple layers of the printed circuit.
Therefore, care should be exercised to avoid pulling the plated circuit out of the hole.
When soldering near the connector pins:
•
Avoid accidentally getting solder in the connector.
•
Be careful not to form solder bridges between the connector pins
•
Closely examine your work for shorts due to solder bridges.
Chip Components
Use the RLN4062 Hot-Air Repair Station for chip component replacement. Adjust the
temperature control to 390 °C (735 °F), and adjust the airflow to a minimum setting. Airflow can
vary due to component density.
•
To remove a chip component:
1.
Use a hot-air hand piece and position the nozzle of the hand piece approximately 0.3 cm
(1/8") above the component to be removed.
2.
Begin applying the hot air. Once the solder reflows, remove the component using a pair
of tweezers.
3.
Using a solder wick and a soldering iron or a power desoldering station, remove the
excess solder from the pads.
1-4
Introduction
•
•
To replace a chip component using a soldering iron:
1.
Select the appropriate micro-tipped soldering iron and apply fresh solder to one of the
solder pads.
2.
Using a pair of tweezers, position the new chip component in place while heating the
fresh solder.
3.
Once solder wicks onto the new component, remove the heat from the solder.
4.
Heat the remaining pad with the soldering iron and apply solder until it wicks to the
component. If necessary, touch up the first side. All solder joints should be smooth and
shiny.
To replace a chip component using hot air:
1.
Use the hot-air hand piece and reflow the solder on the solder pads to smooth it.
2.
Apply a drop of solder paste flux to each pad.
3.
Using a pair of tweezers, position the new component in place.
4.
Position the hot-air hand piece approximately 0.3 cm (1/8”) above the component and
begin applying heat.
5.
Once the solder wicks to the component, remove the heat and inspect the repair. All
joints should be smooth and shiny.
Shields

BOSCH GHG 603 or equivalent.
•
•
To remove the shield:
1.
Place the circuit board in the circuit board holder.
2.
Add solder paste flux around the base of the shield.
3.
Position the heat-focus head onto the shield.
4.
Turn on the heater and wait until the shield lifts off the circuit board.
5.
Once the shield is off, turn off the heat, and grab the part with a pair of tweezers.
6.
Remove the circuit board from the circuit board holder.
To replace the shield:
1.
Add solder to the shield if necessary, using a micro-tipped soldering iron.
2.
Next, rub the soldering iron tip along the edge of the shield to smooth out any excess
solder. Use solder wick and a soldering iron to remove excess solder from the solder
pads on the circuit board.
3.
Place the circuit board back in the circuit board holder.
4.
Place the shield on the circuit board using a pair of tweezers.
5.
Position the heat-focus head over the shield.

(SW/VOL1) and is amplified by U601BTL audio amplifier to a sufficient level to drive a loud speaker.
U601 has mute/un-mute function controlled by audio-mute control (Pin 83) of CPU. When U601
Pin 1 is low, the audio amp goes to active (un-mute) mode. When U601 Pin 1 is high, the audio amp
goes to mute mode.
4.1.3
Internal and External Speaker
When no external speaker is plugged into J601, the RX audio is passed through to the internal
speaker. When an external speaker is plugged into J601, the internal speaker is cut-off from the
rest of the circuit and RX audio is passed through the external speaker.

Memory Usage
Radio operation is controlled by software that is stored in internal Flash ROM memory. Radio
parameters and customer specific information is stored in External EEPROM (U104). The operating
status of the radio is maintained in RAM located within the microprocessor. When the radio is turned
off, the operating status of the radio is written to EEPROM before operating voltage is removed from
the microprocessor.
4.3.2
Control and Indicator Interface
Ports Pin 35 and 36 are outputs which control the Sub-PCB mounted LED indicator. When Pin 35 is
high, the indicator is green. When Pin 36 is high, the indicator is red. When both are high, the
indicator is amber. When both are low, the indicator id is off.
Pressing the side-mounted PTT button (PB501) provides a low to port Pin 44, which indicates PTT is
asserted. Side-mounted function buttons 1 & 2 (PB502 and PB503) are connected to port Pin 21 and
Pin 32, respectively.
4.3.3
Interface to USB programming
The radio can be programmed, or the programmed information can be read, using a computer with
CPS (Customer Programming Software) connected to the radio via a USB Programming cable
(PMDN4077A). Connection to the radio is made via the microphone connector (part of accessory
connector J601). The line connects the programming connect (J601 Pin 6) to port PRG/CLONE_RX
(data into uP, Pin 34) and PRG/CLONE_TX(data out of uP, Pin 33).
4.3.4
Storage of Customer-Specific Information
Information that has been programmed using CPS, such as channel frequencies or selective
signaling codes, etc, are stored in the external EEPROM, where it is retained permanently (unless
reprogrammed) without needing DC power applied to the microprocessor.

C426, C427, C428, C429, C445, C446) and antenna switch (CR301), part of the transmitter circuitry,
before being applied to the receiver front end. The receiver front end consists of preselector filter,
RF amplifier, post-selector filter and a single-balanced mixer.
The preselector filter is a varactor-tuned 2-pole design using discrete elements (L320, L324, C351,
C352, C353, C354, C355, C356, C357, C358, C359, C360, C361) in a series/shunt resonator
configuration. It is a band-shift filter and the frequency shift is controlled by varactor diodes CR314
and CR307, which are connected to the microprocessor. It is configured to provide steeper
attenuation above the passband for improved spurious rejection when low-side local injection is used.
The frequency is separated into 8 steps and controlled by CPU (435 – 480 MHz).
The output of this filter is matched to the base of RF amplifier Q301 which provides 13dB of gain.
The output of the RF amplifier is applied to the post-selector filter. The post-selector filter designed
using discrete elements (L322, L323, L328, C379, C354, C355) in a series/shunt resonator
configuration. It is a band-shift filter and the frequency shift is controlled by varactor diodes CR313,
CR304 and CR305, which are connected to the microprocessor. It is configured to provide steeper
attenuation above the passband for improved spurious rejection when low-side local injection is used.
The frequency is separated into 8 steps and controlled by CPU (435 – 480 MHz).
The output of the post selector is connected to the single-balanced mixer consisting of components
L329, L333, Q306 and Q307. 1st local signal generated from VCO is filtered by injection filter (L310,
L331, C325, C326, C327) to remove second harmonics. The converted 1st IF frequency at mixer
passes through L331 and matches the 45.1 MHz IF signal to pair crystal filter (FL301).
5.2.2
Receiver Back End
The 1st IF signal is amplified about 15 dB by IF amp Q303. The output of the IF amp is connected to
IF IC (U201). 1st IF frequency (45.1 MHz) and 2nd LO frequency (44.645 MHz) are mixed in U201.
The second mixer converts the 45.1 MHz high IF frequency to 2nd IF frequency (455 kHz).
Additional IF selectivity is provided by two ceramic filters (CF1, CF2). The wider filter 455 FW is used
for 25 kHz channel spacing, and the narrower filter 455 HW is used for 12.5 kHz channel spacing.
These two ceramic filters may eliminate undesired signal and demodulated by demodulator in U201.
N/S_SW which connected to microprocessor is used to select the wide and narrow band.
The mute (squelch) circuit switches off the audio amplifier when no audio is present. The squelch
circuit consists of U201 and U202 and their associated components. The noise signal from Pin 9 of
U201 is used to control the squelch circuit sensitivity of U202. The noise passes through filter, and is
amplified by internal amp of U201. The amplified noise act as a DC voltage to control the mute
system. So if the noise level is under the threshold voltage, the microprocessor (U101) un-mutes the
radio. If the noise level is over the threshold voltage, the microprocessor mutes the radio.
The squelch level is tuned in the factory. When a component or a part in the RX system is replaced,
the squelch must be re-tuned using the Tuner.

UHF2 Transmitter
The UHF2 transmitter covers the range of 435 – 480 MHz. Depending on model, the output power of
the transmitter is switchable on a per-channel basis between high power (4 Watts) and low
power (1 Watt). The transmitter is divided into four major blocks as shown in Figure 5-2.

5.3.1
Power Amplifier
The transmitter power amplifier has three stages of amplification – Pre Driver (Q401), Driver
Amp (Q402) and Final Amp (Q403). Signal from TX VCO is applied to the pre driver via an attenuator
circuit. The attenuator is pie style resistor attenuator, and is used as isolation between VCO and the
power amps. The -4dBm TX RF signal from attenuator is then amplified by pre driver and driver amp
to around +25dBm and is applied to the final amp. The final amp (Q403) is an enhancement-mode
N-channel MOSFET device providing a gain of 12dB. The device drain current is drawn directly from
the DC battery supply voltage input via L413. A matching network consisting of C416 to C420 and a
strip line, transforms the impedance to approximately 50 Ohm.
5.3.2
Antenna Switch
An antenna switch works mainly as a switching device between transmit and receive paths. In
transmit mode (PTT), Q407 is turned on and both PIN diodes (CR401, CR301) are forward biased
into conduction. This enables the RF signal to pass to the harmonic filter and then to the antenna. In
the receiver mode, both diodes are off. Signals applied to the antenna jack are routed via the LPF
(harmonic filter), through network L409 to L411, to the receiver input.
5.3.3
Harmonic Filter
The harmonic filter consists of components L409, L410, L411, C426, C427, C428, C429, C430, C445
and C446. The harmonic filter is a seven-pole Chebychev filter.

5.3.4
435 – 480 MHz UHF2 Theory Of Operation: UHF2 Frequency Generation Circuitry
Auto Power Control
The APC keeps the current supply constant to the final amp (Q403). The drain current of Q403 (final
amp) is sensed across resistor R417. The voltage difference across R417 is amplified through U401
by the ratio of R423 to R417. The differential signal at the output of U401 (Pin 7) is passed to Q404
and Q405 that produces a constant power output to the antenna. If the current is changed due to
change of battery voltage or load, APC controls gate voltage of Q403 and collector voltage of Q401
and drain voltage of Q402 to keep TX power stable. This circuit stabilizes TX power at a
pre-determined level adjusted by U402. This bias voltage is tuned in the factory. If the transistor
(Q403) is replaced, the RF Output Power must be tuned. By tuning the RF output power, the bias
voltage will be tuned through U402. Extra care has to be taken during the tuning process. Do not
exceed the maximum allowed bias voltage.

Reference Oscillator (12.8 MHz VCTCXO)
The reference oscillator is powered by regulated 5V provided by U505. The reference frequency
12.8 MHz VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) is applied to
the PLL IC (U701) via Pin 1. Main frequency can be adjusted by chip trimmer of VCTCXO. This
frequency provides reference to the PLL IC and has a frequency stability of +/-2.5PPM (max) at the
temperature ranging from -30 to +60 Degree Celsius.
435 – 480 MHz UHF2 Theory Of Operation: UHF2 Frequency Generation Circuitry
5.4.2
5-5
PLL IC Prescaler and Comparator
The reference frequency from VCTCXO is divided to 6.25 kHz or 5 kHz by reference counter, R. The
RF signal input from the VCO is divided to by prescaler (1/64), divided by N and A counters in PLL IC
to determine frequency steps and then supplied to the comparator. The comparison frequency is
6.25/5 kHz. The internal phase comparator compares the phase difference between the reference
and VCO signal. When the phase of the reference frequency is leading, Pin15 (R) is the output.
When VCO frequency is leading, Pin 16 (P) is the output. When P=R, small pulses are the output of
the phase detector.
5.4.3
Voltage Doubler and Charge Pump
The voltage doubler (U507) converts 5V to 10V and is applied to the charge pump circuitry. The
charge pump is used for charging output signals P, R supplied by PLL IC from 0-3.3V to 0-10V. This
voltage is used to drive the VCO.
5.4.4
Loop Filter
The loop filter contains C751, C752, C753, C754, R726, R727, R728. It reduces the residual sideband noise to get the best signal-to-noise ratio. The output signal from loop filter is applied to VCO.
5.4.5
Dual VCO
The dual VCO module contains a RX VCO and a TX VCO. They are configured as colpitts oscillators
and connected to power up through transistor switches. Only one VCO is selected at a time. A
steering line voltage between 0.35V and 9.7V at varactor CR701 tunes the full RX frequency range
from 389.9MHz to 434.9MHz, and varactor CR702 tunes the full TX frequency range from 435MHz
to 480MHz.
In Receiver mode, high signal of RX_EN from Pin 71, U101 activates Q305. When Q305 is activated,
current flows through the base of Q304 and thus activates the Q705. The varactor CR701 sets the
resonance frequency. When there is a change in voltage supplied by loop filter, there is a change in
the resonance frequency. L703 is the resonating coil, which forms the tank circuit together with
variable cap C710.
In Transmit mode, high signal of TX_EN1 from Pin 84, U101 enables current flows through collector
of Q503 and thus activates Q706. The varactor CR702 sets the resonance frequency. When there is
a change in voltage supplied by loop filter, there is a change in the resonance frequency. L706 is the
resonating tuning coil, which forms the tank circuit together with variable cap C722.

Introduction
This section provides schematic diagrams, overlays, and parts lists for the radio circuit boards and
interface connections.
7.1.1
Notes For All Schematics and Circuit Boards
* Component is frequency sensitive. Refer to the Electrical Parts List for value and usage.
1. Unless otherwise stated, resistance values are in Ohms (K = 1000), capacitance values are in
nanofarads (nF), picofarads (pF) or microfarads (µF), and inductance values are in
nanohenries (nH) or microhenries (µH).
2. DC voltages are measured from point indicated to chassis ground using a Motorola DC
multimeter or equivalent. If the board has been removed from the chassis, the transmitter
module mounting screws may be used for ground connection. (Note: The antenna nut
bracket is connected to ground.) Operating mode dependent voltages are followed by (RX)
for receive mode, (TX) for transmit mode, (UNSQ) for unsquelched mode, etc.
3. RF voltages on VHF models are measured with a Fluke model 85 RF probe. The indicated
voltages expressed in mV (RF) are DC level readings which correspond approximately 1:1 to
the RF voltage level in mV rms. RF voltages in the Receiver Front End and Receiver Back
End circuits are measured with an on-channel 1mV (-47dBm) RF signal applied to the
antenna jack ANT1/ANT.
4. RF voltages on UHF models are measured both with a high–impedance RF voltmeter having
a bandwidth in excess of 500 MHz (levels are expressed in dBm) and with a Fluke model 85
RF probe [levels are expressed in mV (RF)]. These indicated voltages are DC level readings
which correspond approximately 1:1 to the RF voltage level in mV rms, and are only
approximate for UHF frequency measurements. RF voltages in the Receiver Front End and
Receiver Back End circuits are measured with an on-channel 1mV (-47dBm) RF signal
applied to the antenna jack ANT1/ANT.
5. Audio voltages are measured with a high-impedance AC rms voltmeter. The indicated
voltages are expressed in mV rms. Receive mode voltages are followed by (RX) and are
measured with an on-channel signal with 1 kHz modulation at 60% deviation (3 kHz for 25
kHz channels, or 1.5 kHz for 12.5 kHz channels). Transmit mode voltages are followed by
(TX) and are measured with a 1 kHz, 10 mV rms signal present at the external microphone
input (accessory connector J601).

8.1
Introduction
This chapter provides a detailed theory of operation for the radio components. Schematic diagrams
for the circuits described in the following paragraphs are located in Chapter 10 of this manual.
8.2
VHF Receiver
The VHF receiver design covers the frequency range of 136 – 174 MHz and it is a double
conversion super heterodyne with 1st IF 45.1 MHz and 2nd IF 455 kHz. The receiver is divided into
two major blocks, Front End and Back End as shown in Figure 8-1.

8.2.1
136 – 174 MHz VHF Theory Of Operation: VHF Receiver
Receiver Front End
Incoming RF signals from antenna are first routed through the harmonic filter (L409, L410, L411,
C426, C427, C428, C429, C445, C446) and antenna switch (CR301), part of the transmitter circuitry,
before being applied to the receiver front end. The receiver front end consists of preselector filter, RF
amplifier, post-selector filter and a single-balanced mixer.
The preselector filter is a varactor-tuned 2-pole design using discrete elements (L301, L302, L303,
L304, C301, C304, C305, C307) in a shunt or series resonator configuration. It is a band-shift filter
and the frequency shift is controlled by varactor diodes CR302 and CR303, which are connected to
the microprocessor. It is configured to provide steeper attenuation above the passband for improved
spurious rejection when high-side local injection is used. The frequency is separated into 6 steps and
controlled by CPU (136 – 174 MHz).
The output of this filter is matched to the base of RF amplifier Q301 which provides 15dB of gain.
The output of the RF amplifier is applied to the post-selector filter. The post-selector filter designed
using discrete elements (L307, L308, L309, L311, C315 and C354) in a series/shunt resonator
configuration. It is a band-shift filter and the frequency shift is controlled by varactor diodes CR305
and CR307, which are connected to the microprocessor. It is configured to provide steeper
attenuation above the passband for improved spurious rejection when low-side local injection is used.
The frequency is separated into 6 steps and controlled by CPU (136 – 174 MHz).
The output of the post selector is connected to the single-balanced mixer consisting of components
L329, L333, Q306 and Q307. 1st local signal generated from VCO is filtered by injection
filter (L310, L331, C325, C326, C327, C333 and C365) to remove second harmonics. The converted
1st IF frequency at mixer passes through L331 and matches the 45.1 MHz IF signal to pair crystal
filter (FL301).
8.2.2
Receiver Back End
The 1st IF signal is amplified about 15 dB by IF amp Q303. The output of the IF amp is connected to
IF IC (U201). 1st IF frequency (45.1 MHz) and 2nd LO frequency (44.645 MHz) are mixed in U201.
The second mixer converts the 45.1 MHz high IF frequency to 2nd IF frequency (455 kHz).
Additional IF selectivity is provided by two ceramic filters (CF1, CF2). The wider filter 455 FW is used
for 25 kHz channel spacing, and the narrower filter 455 HW is used for 12.5 kHz channel spacing.
These two ceramic filters may eliminate undesired signal and demodulated by demodulator in U201.
N/S_SW which connected to microprocessor is used to select the wide and narrow band.
The mute (squelch) circuit switches off the audio amplifier when no audio is present. The squelch
circuit consists of U201 and U202 and their associated components. The noise signal from pin 9 of
U201 is used to control the squelch circuit sensitivity of U202. The noise passes through filter, and is
amplified by internal amp of U201. The amplified noise act as a DC voltage to control the mute
system. So if the noise level is under the threshold voltage, the microprocessor (U101) un-mutes the
radio. If the noise level is over the threshold voltage, the microprocessor mutes the radio. The
squelch level is tuned in the factory. When a component or a part in the RX system is replaced, the
squelch must be re-tuned using the Tuner.
136 – 174 MHz VHF Theory Of Operation: VHF Transmitter

8-3
VHF Transmitter
The VHF transmitter covers the range of 136 – 174 MHz. Depending on model, the output power of
the transmitter is switchable on a per-channel basis between high power (5 Watts) and low
power (1 Watt). The transmitter is divided into four major blocks as shown in Figure 8-2.

8.3.1
Power Amplifier
The transmitter power amplifier has three stages of amplification – Pre Driver (Q401), Driver Amp
(Q402) and Final Amp (Q403). Signal from TX VCO is applied to the pre driver via an attenuator
circuit. The attenuator is pie style resistor attenuator, and is used as isolation between VCO and the
power amps. The -3dBm TX RF signal from attenuator is then amplified by pre driver and driver amp
to around +28dBm and is applied to the final amp. The final amp (Q403) is an enhancement-mode
N-channel MOSFET device providing a gain of 12dB. The device drain current is drawn directly from
the DC battery supply voltage input via L413. A matching network consisting of C417, C418, C419,
C420, C455 and a strip line, transforms the impedance to approximately 50 Ohm.
8.3.2
Antenna Switch
An antenna switch works mainly as a switching device between transmit and receive paths. In
transmit mode (PTT), Q407 is turned on and both PIN diodes (CR401, CR301) are forward biased
into conduction. This enables the RF signal to pass to the harmonic filter and then to the antenna. In
the receiver mode, both diodes are off. Signals applied to the antenna jack are routed via the LPF
(harmonic filter), through a TX Low Pass Filter (L409, L410, L411, C426, C427, C428, C429, C430,
C445 and C446), to the receiver input.
8.3.3
Harmonic Filter
The harmonic filter consists of components L409, L410, L411, C426, C427, C428, C429, C430, C445
and C446. The harmonic filter is a seven-pole Chebychev filter.

8.3.4
136 – 174 MHz VHF Theory Of Operation: VHF Frequency Generation Circuitry
Auto Power Control
The APC keeps the current supply constant to the final amp (Q403). The drain current of Q403 (final
amp) is sensed across resistor R417. The voltage difference across R417. The differential signal at
the output of U401 (pin 7) is passed to Q404 and Q405 that produces a constant power output to the
antenna. If the current is changed due to change of battery voltage or load, APC controls gate voltage
of Q403 and collector voltage of Q401 and drain voltage of Q402 to keep TX power stable. This circuit
stabilizes TX power at a pre-determined level adjusted by U402. This bias voltage is tuned in the
factory. If the transistor (Q403) is replaced, the RF Output Power must be tuned. By tuning the RF
output power, the bias voltage will be tuned through U402. Extra care has to be taken during the
tuning process. Do not exceed the maximum allowed bias voltage.

Reference Oscillator (12.8 MHz VCTCXO)
The reference oscillator is powered by regulated 5V provided by U505. The reference frequency
12.8 MHz VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) is applied to
the PLL IC (U701) via pin 1. Main frequency can be adjusted by chip trimmer of VCTCXO. This
frequency provides reference to the PLL IC and has a frequency stability of +/-2.5PPM (max) at the
temperature ranging from -30 to +60 Degree Celsius.

8.4.2
8-5
PLL IC Prescaler and Comparator
The reference frequency from VCTCXO is divided to 6.25 kHz or 5 kHz by reference counter, R. The
RF signal input from the VCO is divided to by prescaler (1/64), divided by N and A counters in PLL IC
to determine frequency steps and then supplied to the comparator. The comparison frequency is
6.25/5 kHz. The internal phase comparator compares the phase difference between the reference
and VCO signal. When the phase of the reference frequency is leading, Pin15 (R) is the output.
When VCO frequency is leading, Pin16 (P) is the output. When P=R, small pulses are the output of
the phase detector.
8.4.3
Voltage Doubler and Charge Pump
The voltage doubler (U507) converts 5V to 10V and is applied to the charge pump circuitry. The
charge pump is used for charging output signals P, R supplied by PLL IC from 0-3.3V to 0-10V. This
voltage is used to drive the VCO.
8.4.4
Loop Filter
The loop filter contains C751, C752, C753, C754, R726, R727, R728. It reduces the residual sideband noise to get the best signal-to-noise ratio. The output signal from loop filter is applied to VCO.
8.4.5
Dual VCO
The dual VCO module contains a RX VCO and a TX VCO. They are configured as colpitts oscillators
and connected to power up through transistor switches. Only one VCO is selected at a time. A
steering line voltage between 0.35V and 9.7V at varactor CR701 tunes the full RX frequency range
from 181.1 MHz to 219.1 MHz, and varactor CR703 tunes the full TX frequency range from 136 MHz
to 174 MHz.
In Receiver mode, high signal of RX_EN from pin 71, U101 activates Q305. When Q305 is activated,
current flows through the base of Q304 and thus activates the Q705. The varactor CR701 sets the
resonance frequency. When there is a change in voltage supplied by loop filter, there is a change in
the resonance frequency. L703 is the resonating coil, which forms the tank circuit together with
variable cap C710.
In Transmit mode, high signal of TX_EN1 from pin 84, U101 enables current flows through collector
of Q503 and thus activates Q706. The varactor CR703 sets the resonance frequency. When there is
a change in voltage supplied by loop filter, there is a change in the resonance frequency. L706 is the
resonating tuning coil, which forms the tank circuit together with variable cap C722.

1. All voltages are measured with a high-impedance digital voltmeter and expressed in volts DC relative to ground (0V).
2. Voltages are measured with a DC input voltage of 7.50 + .02 volts DC applied to the battery connector (J602).
3. All voltages are measured in the squelched receive mode, unless otherwise indicated.
4. Voltages are identical for VHF and UHF models unless otherwise indicated.
Chapter 10 VHF Schematic Diagrams, Overlays, and
Parts Lists
10.1 Introduction
This section provides schematic diagrams, overlays, and parts lists for the radio circuit boards and
interface connections.
10.1.1 Notes For All Schematics and Circuit Boards
* Component is frequency sensitive. Refer to the Electrical Parts List for value and usage.
1. Unless otherwise stated, resistance values are in Ohms (K = 1000), capacitance values are in
nanofarads (nF), picofarads (pF) or microfarads (µF), and inductance values are in
nanohenries (nH) or microhenries (µH).
2. DC voltages are measured from point indicated to chassis ground using a Motorola DC
multimeter or equivalent. If the board has been removed from the chassis, the transmitter
module mounting screws may be used for ground connection. (Note: The antenna nut
bracket is connected to ground.) Operating mode dependent voltages are followed by (RX)
for receive mode, (TX) for transmit mode, (UNSQ) for unsquelched mode, etc.
3. RF voltages on VHF models are measured with a Fluke model 85 RF probe. The indicated
voltages expressed in mV (RF) are DC level readings which correspond approximately 1:1 to
the RF voltage level in mV rms. RF voltages in the Receiver Front End and Receiver Back
End circuits are measured with an on-channel 1mV (-47dBm) RF signal applied to the
antenna jack ANT1/ANT.
4. RF voltages on UHF models are measured both with a high–impedance RF voltmeter having
a bandwidth in excess of 500 MHz (levels are expressed in dBm) and with a Fluke model 85
RF probe [levels are expressed in mV (RF)]. These indicated voltages are DC level readings
which correspond approximately 1:1 to the RF voltage level in mV rms, and are only
approximate for UHF frequency measurements. RF voltages in the Receiver Front End and
Receiver Back End circuits are measured with an on-channel 1mV (-47dBm) RF signal
applied to the antenna jack ANT1/ANT.
5. Audio voltages are measured with a high-impedance AC rms voltmeter. The indicated
voltages are expressed in mV rms. Receive mode voltages are followed by (RX) and are
measured with an on-channel signal with 1 kHz modulation at 60% deviation (3 kHz for 25
kHz channels, or 1.5 kHz for 12.5 kHz channels). Transmit mode voltages are followed by
(TX) and are measured with a 1 kHz, 10 mV rms signal present at the external microphone
input (accessory connector J601).

Chapter 11 403 – 447 MHz UHF1 Theory Of Operation
11.1 Introduction
This chapter provides a detailed theory of operation for the radio components. Schematic diagrams
for the circuits described in the following paragraphs are located in Chapter 14 of this manual.
11.2 UHF1 Receiver
The UHF1 receiver design covers the frequency range of 403 – 447MHz and it is a double
conversion super heterodyne with 1st IF 45.1MHz and 2nd IF 455kHz. The receiver is divided into
two major blocks, Front End and Back End as shown in Figure 11-1.

403 – 447 MHz UHF1 Theory Of Operation: UHF1 Receiver
11.2.1 Receiver Front End
Incoming RF signals from antenna are first routed through the harmonic filter (L409 – L411, C426 –
C429, C445, C446) and antenna switch (CR301), part of the transmitter circuitry, before being applied
to the receiver front end. The receiver front end consists of preselector filter, RF amplifier, postselector filter and a double-balanced mixer.
The preselector filter is a varactor-tuned 2-pole design using discrete elements (L320, L324, C351,
C361, CR307 and CR314) in series/shunt resonator configuration. It is a band-shift filter and the
frequency shift is controlled by varactor diodes CR307 and CR314, which are connected to the
microprocessor. It is configured to provide steeper attenuation above the pass band for improved
spurious rejection when high-side local injection is used. The frequency is separated into 8 steps and
controlled by CPU (403 – 447MHz).
The output of this filter is matched to the base of RF amplifier Q301 which provides 13dB of gain. The
output of the RF amplifier is applied to the post-selector filter. The post-selector filter designed using
discrete elements (L323, L328, C379, C363 and C355) in a series/shunt resonator configuration. It is
a band-shift filter and the frequency shift is controlled by varactor diodes CR305 and CR313, which
are connected to the microprocessor. It is configured to provide steeper attenuation above the
passband for improved spurious rejection when high-side local injection is used. The frequency is
separated into 8 steps and controlled by CPU (403 – 447MHz).
The output of the post selector is connected to the double-balanced mixer consisting of components
L329, L333, CR316. 1st local signal generated from VCO is filtered by injection filter (L310, L331,
C325, C326, C388, C386, C365 and C387) to remove harmonics. The converted 1st IF frequency at
mixer passes through L333 and matches the 45.1MHz IF signal to crystal filter (FL301).
11.2.2 Receiver Back End
The 1st IF signal is amplified about 15dB by IF amp Q303. The output of the IF amp is connected to
IF IC (U201).
1st IF frequency (45.1MHz) and 2nd LO frequency (44.645MHz) are mixed in U201. The second
mixer converts the 45.1MHz high IF frequency to 2nd IF frequency (455kHz).
Additional IF selectivity is provided by two ceramic filters (CF1, CF2). The wider filter 455FW is used
for 25kHz channel spacing, and the narrower filter 455HW is used for 12.5kHz channel spacing.
These two ceramic filters may eliminate undesired signal and demodulated by demodulator in U201.
N/S_SW which connected to microprocessor is used to select the side and narrow band.
The mute (squelch) circuit switches off the audio amplifier when no audio is present. The squelch
circuit consists of U201 and U202 and their associated components. The noise signal from Pin 9 of
U201 is used to control the squelch circuit sensitivity of U202. The noise passes through filter, and is
amplified by internal amp of U201. The amplified noise acts as a DC voltage to control the mute
system. So if the noise level is under the threshold voltage, the microprocessor (U101) un-mutes the
radio. If the noise level is over the threshold voltage, the microprocessor mutes the radio. The
squelch level is tuned in the factory. When a component or a part in the RX system is replaced, the
squelch must be re-tuned using the Tuner.

11.3 UHF1 Transmitter
The UHF1 transmitter covers the range of 403 – 447MHz. Depending on model, the output power of
the transmitter is switchable on a per-channel basis between high power (4 Watt) and low power (1
Watt). The transmitter is divided into four major blocks as shown in Figure 11-2.

11.3.1 Power Amplifier
The transmitter power amplifier has three stages of amplification – Pre Driver (Q401), Driver Amp
(Q402) and Final Amp (Q403). Signal from TX VCO is applied to the pre driver via an attenuator
circuit. The attenuator is pie style resistor attenuator, and is used as isolation between VCO and the
power amps. The -4dBm TX RF signal from attenuator is then amplified by pre driver and driver amp
to around +25dBm and is applied to the final amp. The final amp (Q403) is an enhancement-mode
N-channel MOSFET device providing a gain of 12dB. The device drain current is drawn directly from
the DC battery supply voltage input via L413. A matching network consisting of C416, C417, C418,
C419, C420, C451, C422, C452 and a strip line, transforms the impedance to approximately 50Ohm.
11.3.2 Antenna Switch
An antenna switch works mainly as a switching device between transmit and receive paths. In
transmit mode (PTT), Q407 is turned on and both PIN diodes (CR401, CR301) are forward biased
into conduction. This enables the RF signal to pass to the harmonic filter and then to the antenna. In
the receiver mode, both diodes are off. Signals applied to the antenna jack are routed via the LPF
(harmonic filter), through network L409, L410, L411, C426, C427, C428, C429, C430, C445, C446 to
the receiver input.
11.3.3 Harmonic Filter
The harmonic filter consists of components L409, L410, L411, C426, C427, C428, C429, C430, C445
and C446. The harmonic filter is a seven-pole Chebychev filter.

403 – 447 MHz UHF1 Theory Of Operation: UHF1 Frequency Generation Circuitry
11.3.4 Auto Power Control
The APC keeps the current supply constant to the final amp (Q403). The drain current of Q403 (final
amp) is sensed across resistor R417. The differential signal at the output of U401 (Pin 7) is passed to
Q404 and Q405 that produces a constant power output to the antenna. If the current is changed due
to change of battery voltage or load, APC controls gate voltage of Q403 and collector voltage of Q401
and drain voltage of Q402 to keep TX power stable. This circuit stabilizes TX power at a predetermined level adjusted by U402. This bias voltage is tuned in the factory. If the transistor (Q403) is
replaced, the RF Output Power must be tuned. By tuning the RF output power, the bias voltage will be
tuned through U402. Extra care has to be taken during the tuning process. Do not exceed the
maximum allowed bias voltage.

11.4.1 Reference Oscillator (12.8 MHz VCTCXO)
The reference oscillator is powered by regulated 5V provided by U505. The reference frequency
12.8MHz VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) is applied to
the PLL IC (U701) via Pin 1. Min frequency can be adjusted by chip trimmer of VCTCXO. This
frequency provides reference to the PLL IC and has a frequency stability of +/-2.5PPM (max) at the
temperature ranging from -30 to +60 Degree Celsius.
403 – 447 MHz UHF1 Theory Of Operation: UHF1 Frequency Generation Circuitry
11-5
11.4.2 PLL IC Prescaler and Comparator
The reference frequency from VCTCXO is divided to 6.25kHz or 5kHz by reference counter, R. The
RF signal input from the VCO is divided to by prescaler (1/64), divided by N and A counters in PLL IC
to determine frequency steps and then supplied to the comparator. The comparison frequency is
6.25/5kHz. The internal phase comparator compares the phase difference between the reference
and VCO signal. When the phase of the reference frequency is leading, Pin 15(R) is the output.
When VCO frequency is leading, Pin 16 (P) is the output. When P=R, small pulses are the output of
the phase detector.
11.4.3 Voltage Doubler and Charge Pump
The voltage doubler (U507) converts 5V to 10V and is applied to the charge pump circuitry. The
charge pump is used for charging output signals P, R supplied by PLL IC from 0-3.3v to 0-10v. This
voltage is used to drive the VCO.
11.4.4 Loop Filter
The loop filter contains C751 – C754, R726 – R728. It reduces the residual side-band noise to get
the best signal-to noise ratio. The output signal from loop filter is applied to VCO.
11.4.5 Dual VCO
The dual VCO module contains a RX VCO and a TX VCO. They are configured as colpitts oscillators
and connected to power up through transistor switches. Only one VCO is selected at a time. A
steering line voltage between 0.35V and 9.7V at varactor CR701 tunes the fill RX frequency range
from 357.9MHz to 401.9MHz and varactor CR703 tunes the full TX frequency range from 403MHz to
447MHz.
In Receiver mode, high signal of RX_EN from Pin 71, U101 activates Q305. When Q305 is activated,
current flows through the base of Q304 and thus activates the Q705. The varactor CR701 sets the
resonance frequency. When there is a change in voltage supplied by loop filter, there is a change in
the resonance frequency. L703 is the resonating coil, which forms the tank circuit together with
variable cap C710.
In Transmit mode, high signal of TX_EN1 from Pin 84, U101 enables current flows through collector
of Q503 and thus activates Q706. The varactor CR703 sets the resonance frequency. When there is
a change in voltage supplied by loop filter, there is a change in the resonance frequency. L706 is the
resonating tuning coil, which forms the tank circuit together with variable cap C722.

Chapter 13 UHF1 Schematic Diagrams, Overlays, and
Parts Lists
13.1 Introduction
This section provides schematic diagrams, overlays, and parts lists for the radio circuit boards and
interface connections.
13.1.1 Notes For All Schematics and Circuit Boards
* Component is frequency sensitive. Refer to the Electrical Parts List for value and usage.
1. Unless otherwise stated, resistance values are in Ohms (K = 1000), capacitance values are in
nanofarads (nF), picofarads (pF) or microfarads (µF), and inductance values are in
nanohenries (nH) or microhenries (µH).
2. DC voltages are measured from point indicated to chassis ground using a Motorola DC
multimeter or equivalent. If the board has been removed from the chassis, the transmitter
module mounting screws may be used for ground connection. (Note: The antenna nut
bracket is connected to ground.) Operating mode dependent voltages are followed by (RX)
for receive mode, (TX) for transmit mode, (UNSQ) for unsquelched mode, etc.
3. RF voltages on VHF models are measured with a Fluke model 85 RF probe. The indicated
voltages expressed in mV (RF) are DC level readings which correspond approximately 1:1 to
the RF voltage level in mV rms. RF voltages in the Receiver Front End and Receiver Back
End circuits are measured with an on-channel 1mV (-47dBm) RF signal applied to the
antenna jack ANT1/ANT.
4. RF voltages on UHF models are measured both with a high–impedance RF voltmeter having
a bandwidth in excess of 500 MHz (levels are expressed in dBm) and with a Fluke model 85
RF probe [levels are expressed in mV (RF)]. These indicated voltages are DC level readings
which correspond approximately 1:1 to the RF voltage level in mV rms, and are only
approximate for UHF frequency measurements. RF voltages in the Receiver Front End and
Receiver Back End circuits are measured with an on-channel 1mV (-47dBm) RF signal
applied to the antenna jack ANT1/ANT.
5. Audio voltages are measured with a high-impedance AC rms voltmeter. The indicated
voltages are expressed in mV rms. Receive mode voltages are followed by (RX) and are
measured with an on-channel signal with 1 kHz modulation at 60% deviation (3 kHz for 25
kHz channels, or 1.5 kHz for 12.5 kHz channels). Transmit mode voltages are followed by
(TX) and are measured with a 1 kHz, 10 mV rms signal present at the external microphone
input (accessory connector J601).

Warranty, Service Support, and Replacement Parts: Warranty
A.2.6 Piece Parts
Some replacement parts, spare parts, and/or product information can be ordered directly. If a
complete Motorola part number is assigned to the part, it is available from Motorola’s Managed
Technical Services (MTS). If no part number is assigned, the part is not normally available from
Motorola. If the part number is appended with an asterisk, the part is serviceable by Motorola Depot
only. If a parts list is not included, this generally means that no user-serviceable parts are available
for that kit or assembly.
All orders for parts/information should include the complete Motorola identification number. Request
for help in identification of non-referenced spare parts should be directed to the Motorola’s local area
representation. When damaged parts are replaced, identical parts should be used. If the identical
replacement part is not locally available, check the parts list for the proper Motorola part number.
Orders for replacement parts which are listed in the “Parts List” section of this manual, should be
placed directly on Motorola’s local distribution organization or via Motorola Online (Extranet).
