Chapter 2 Maintenance

2.1 Introduction

This chapter provides details about the following:
• Preventive Maintenance
• Safe Handling of CMOS and LDMOS Devices
• General Repair Procedures and Techniques
• Disassembling and Reassembling the Radio

2.2 Preventive Maintenance

The radio does not require a scheduled preventive maintenance program; however, periodic visual inspection and cleaning is recommended.

2.2.1 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.

2.2.2 Cleaning Procedures

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 service or repair.
The only recommended agent for cleaning external radio surfaces is a 0.5% solution of a mild dishwashing detergent in water. The only factory recommended liquid for cleaning printed circuit boards and their components is isopropyl alcohol (70% by volume).
CAUTION: The effects of certain chemicals and their vapors can have harmful results on certain
plastics. Avoid using aerosol sprays, tuner cleaners, and other chemicals.
2.2.2.1 Cleaning External Plastic Surfaces
Apply the 0.5% detergent-water solution sparingly with a stiff, non-metallic, short-bristled brush to work all loose dirt away from the radio. Use a soft, absorbent, lintless cloth or tissue to remove the solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks, or crevices.
2.2.2.2 Cleaning Internal Circuit Boards and Components
Apply Isopropyl alcohol (70%) 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. After completing 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.
Page 16
2-2
Maintenance
NOTE: 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 Devices

2.3 Safe Handling of CMOS and LDMOS Devices

Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios, and are 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 following CAUTION statement.
CAUTION: This radio contains static-sensitive devices. Do not open the radio unless you are
properly grounded. Take the following precautions when working on this unit:
• Store and transport all CMOS devices in conductive material so that all exposed leads are shorted together. Do not insert CMOS devices into conventional plastic “snow” trays used for storage and transportation of other semiconductor devices.
• Ground the working surface of the service bench to protect the CMOS device. We recommend using the Motorola Static Protection Assembly (part number 0180386A82), which includes a wrist strap, two ground cords, a table mat, and a floor mat.
• Wear a conductive wrist strap in series with a 100k resistor to ground. (Replacement wrist straps that connect to the bench top covering are Motorola part number RSX-
4015.)
• Do not wear nylon clothing while handling CMOS devices.
• Do not insert or remove CMOS devices with power applied. Check all power supplies used for testing CMOS devices to be certain that there are no voltage transients present.
• When straightening CMOS pins, provide ground straps for the apparatus used.
• When soldering, use a grounded soldering iron.
• If at all possible, handle CMOS devices by the package and not by the leads. Prior to touching the unit, touch an electrical ground to remove any static charge that you may have accumulated. The package and substrate may be electrically common. If so, the reaction of a discharge to the case would cause the same damage as touching the leads.

2.4 Repair Procedures and Techniques — General

2.4.1 Parts Replacement and Substitution

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 and order the part from the nearest Motorola Communications parts center listed in the Piece Parts section of this manual.

2.4.2 Rigid Circuit Boards

This radio 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 printed­through holes may interconnect multiple layers of the printed circuit. Therefore, exercise care to avoid pulling the plated circuit out of the hole.
August 30, 2002 99R85452E01-O
Page 17
Maintenance
: Repair Procedures and Techniques — General 2-3
When soldering near the 20-pin and 40-pin connectors:
• Avoid accidentally getting solder in the connector.
• Be careful not to form solder bridges between the connector pins.
• Examine your work closely for shorts due to solder bridges.

2.4.3 Flexible Circuits

The flexible circuits are made from a different material than the rigid boards, and require different soldering techniques. Excessive prolonged heat on a flexible circuit can damage the material. Therefore, avoid excessive heat and excessive bending.
For parts replacement, use the ST-1087 Temperature-Controlled Solder Station with a 600-700 degree F tip, and use small diameter solder such as ST-633. The smaller size solder will melt faster and require less heat to be applied to the circuit.
To replace a component on a flexible circuit:
1. Grasp with seizers (hemostats) the edge of the flexible circuit near the part to be removed.
2. Pull gently.
3. Apply the tip of the soldering iron to the component connections while pulling with the seizers.
NOTE: Do not attempt to puddle-out components. Prolonged application of heat may damage the
flexible circuit.

2.4.4 Chip Components

Use either the RLN-4062 Hot-Air Repair Station or the Motorola 0180381B45 Repair Station for chip component replacement. When using the 0180381B45 Repair Station, select the TJ-65 mini­thermojet hand piece. On either unit, adjust the temperature control to 700 degrees F. (370 degrees C), and adjust the airflow to a minimum setting. Airflow can vary due to component density.
• To remove a chip component, select a hot-air hand piece and position the nozzle of the hand piece approximately 1/8” above the component to be removed. Begin applying hot air. Once the solder reflows, remove the component using a pair of tweezers. Using solder wick and a soldering iron or a power desoldering station, remove the excess solder from the pads.
• To replace a chip component using a soldering iron, select the appropriate micro-tipped soldering iron and apply fresh solder to one of the solder pads. Using a pair of tweezers, position the new chip component in place while heating the fresh solder. Once solder wicks onto the new component, remove the heat from the solder. 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, select the hot-air hand piece and reflow the solder on the solder pads to smooth it. Apply a drop of solder paste flux to each pad. using a pair of tweezers, position the new component in place. Position the hot-air hand piece approximately 1/8” above the component and begin applying heat. Once the solder wicks to the component, remove the heat and inspect the repair. All joints should be smooth and shiny.
Page 18
2-4

2.4.5 Shields

Removing and replacing shields will be done with the R-1070 station with the temperature control set to approximately 415°F (215°C); 445°F (230°C) max.
• To remove the shield, place the circuit board in the R-1070’s holder. Select the proper heat focus head and attach it to the heater chimney. Add solder paste flux around the base of the shield. Position the shield under the heat-focus head. Lower the vacuum tip and attach it to the shield by turning on the vacuum pump. Lower the focus head until it is approximately 1/8” (0.3cm) above the shield. Turn on the heater and wait until the shield lifts off the circuit board. Once the shield is off, turn off the heat, grab the part with a pair of tweezers, and turn off the vacuum pump. Remove the circuit board from the R-1070’s circuit board holder.
• To replace the shield, add solder to the shield if necessary, using a micro-tipped soldering iron. 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. Place the circuit board back in the R1070’s circuit board holder. Place the shield on the circuit board using a pair of tweezers. Position the heat-focus head over the shield and lower it to approximately 1/8” above the shield. Turn on the heater and wait for the solder to reflow. Once complete, turn off the heat, raise the heat-focus head and wait approximately one minute for the part to cool. Remove the circuit board and inspect the repair. No cleaning should be necessary.

Chapter 4 Radio Programming

4.1 Introduction

The PRO2150 Portable Radio can be programmed by using the Customer Programming Software (CPS).

4.2 Programming Your Radio

4.2.1 Overview of the Programming Process

To prepare properly programmed radios for your customers, you should:
1. Program one radio with all the necessary parameters, as required by your customers.
2. Clone these parameters over to all your customer’s radios.

4.2.2 Cloning Radio Parameters to User Radios

Cloning duplicates the contents of Radio 1 (master radio) into Radio 2 (slave radio). However, tuning and alignment information are not affected by cloning.

4.2.3 Parameters Which are Cloned

• Radio Wide parameters
• Channel settings
• VFO settings

4.2.4 Parameters Which are Not Cloned

• All hardware tuning and alignment parameters
• Unit Serial Number

4.2.5 To Clone a Radio

Cloning duplicates the contents of your radio (master radio) into your customer’s radio (slave radio). Tuning and alignment information are not affected by cloning.
1. Turn off both the master and slave radios (if any of them are turned on).
2. Connect both radios with the cloning cable through the Programming Port (lower port of the Accessory Connector).
3. Turn on the slave radio.
4. Press and hold the A button, and turn on the master radio.
5. The master radio displays CLONE if cloning can proceed, otherwise an error message is shown.
6. The slave radio displays PROG while it is being programmed.
7. When cloning is completed, the master radio displays END, and the slave radio resets automatically.
8. Disconnect radios from the cloning cable. They are now ready for operation.
Page 38

The above figure illustrates the DC distribution throughout the radio board. A battery supplies power directly to the electronic on/off control. Radio power supply is triggered by the Power Switch (On/ Off/Volume control) and +SW B is distributed as show in the figure. Regulator output 5V is supplied to the CPU. +SW B continues to support the Audio Power AMP, 5V Regulator, TX Regulator until the radio is turned off.

RX +5V
The radio can be turned off on two ways:
1. Power Switch turned-off
2. Low Battery
When a low battery level is detected by the CPU, it stores the radio personality data to EEPROM before turning off the radio.

7.3.3 Power up Sequence

1. Power supply is turned on by the On/Off/Volume Control (Power Switch).
2. Power from battery is supplied to the regulator through the switch.
3. Output (5V) from the regulator is directed to the CPU (Q101).
4. Q105 resets the CPU (Q101).
5. The CPU loads radio personality data from EEPROM after the reset.
6. This personality data is used to initialize the radio.
Page 50
7-4
7. The radio restores last power up state (i.e. state before the radio was turned-off).
8. Power is supplied to PLL circuitry.
9. Power is supplied to Rx and Rx VCO circuitry.
10. CPU sends data to PLL circuitry. If LOCK status is confirmed, radio continues the power-up sequence. Otherwise, PLL ERR is displayed.
11. If the Rx audio level is less than the pre-programmed squelch level, and other unmuting conditions are met, the radio will open squelch.

7.3.4 CPU / Control Section

When the radio is turned ON, the CPU (Q101) reads the radio status from the EEPROM Q114. It also monitors the keypad, the PTT line and other inputs such as the squelch detect, etc. continuously. When there is a channel change, the CPU sends the correct frequency information to the synthesizer via pins 1, 2 and 89. The CPU is clocked by the 8.388608MHz oscillator, which is composed of X101, C101, C106, and R158.

7.3.5 VCO / Synthesizer Section

This section consists of the Temperature-Compensated Crystal Oscillator (TCXO), Voltage Controlled Oscillator (VCO), Synthesizer and the Loop Filter. These circuits are found on the RF board.
VHF Band Information
: Theory of Operation
7.3.5.1 Temperature-Compensated Crystal Oscillator (TCXO)
The reference oscillator is a temperature compensated crystal-controlled, Pierce type circuit. It utilizes a logic gate within Q323 as a gain element. C335 is used to adjust the oscillator on frequency (14.4MHz) at room temperature (22°C). Temperature variations cause resistance changes in thermistor R330 and R567, which is on the base of Q320, thus varying the voltage applied to varactor Q322. This changes the impedance across crystal X301 in a manner complementary to the temperature drift characteristic of the crystal. In this way, the reference oscillator is held within the specified ±2.5 PPM from -30 to +60°C.
7.3.5.2 Voltage-Controlled Oscillators
Only one of the VCOs runs at a time, which is controlled by Q310 and Q101. The receive VCO consists of C344-C351, L302, L305, L306, L312-L314, Q311, and Q324. This VCO oscillates at 45.1 MHz above the programmed receive frequency. The VCO’s oscillating frequency is tuned by the varactor Q311. The tuning voltage is supplied from the output of the Loop Filter. The output of the VCO is AC coupled (C352) to the buffer Q308. The output of the VCO buffer Q308 is AC coupled (C308) to the synthesizer and the output buffer Q416 respectively.
When the PTT is pressed, Q101 pin36 goes low (approx. 0V) disabling the receive VCO by the Q310 and biases on Q309 to enable the transmitter VCO. The transmitter VCO consists of C353, C355, C357, C358, L315, L317, L318, Q325, Q326, and Q329. This VCO oscillates on the programmed transmit frequency. The VCO’s oscillating frequency is tuned by the varactor Q326. The tuning voltage is supplied from the output of the Loop Filter. The transmit voltage controlled oscillator is directly frequency-modulated and operates on the carrier frequency. The synthesizer is tuned in
5.00kHz or 6.25kHz steps.
7.3.5.3 Synthesizer
The frequency synthesizer is a large-scale monolithic synthesizer integrated circuit Q323. The synthesizer IC contains a dual modulus prescaler, programmable divide-by-N counter, prescale control (swallow) counter, reference oscillator, reference divider, phase detector, charge pump and lock detector. Also, included in Q323 are shift registers and control circuits for frequency controls and general device control.
August 30, 2002 99R85452E01-O
Page 51
VHF Band Information
RF output from the active VCO is AC coupled to the synthesizer Q323 prescaler input at Pin 8. The divide counter chain in Q323, consisting of the dual-modulus prescaler, swallow counter and programmable counter, divides the VCO signal down to a frequency very close to 5.00kHz or
6.25kHz which is applied to the phase detector. The phase comparator compares the phase with the
5.00kHz or 6.25kHz reference signal from the reference divider and drives the external charge pump (Q314, Q315 and Q316). The synthesizer unlock detector circuit prevents the operation of the transmitter and receiver, when the phase lock loop (PLL) is unlocked. The following discussion assumes the unit has been placed in the transmit mode. Q323 lock detector Pin 7 goes high when the PLL is locked. This high level is applied to Pin 25 of the CPU Q101. A software timing routing brings the RX/TX line low (Pin 36 of Q101). With the RX/TX line goes low, Q209 is cut off and Q208 is biased on passing +5VTX-B to Q202; it biases on Q201 to pass switched TX-B to the transmitter amplifier string which enables transmission.
When the PLL is unlocked, the lock detector at Q323 Pin 7 will begin pulsing low. A RC circuit converts this low pulse to a low level for the CPU. The CPU then changes the RX/TX line to a high, thus signaling the other transistor switches to drive Q201 into cutoff, which disables transmission. Therefore, the transmitter remains disabled while the loop remains out of lock, and “PLL ERR” is displayed.
7.3.5.4 Loop Filter
The Loop Filter, a passive lead-lag filter consisting of R314-R317, R356, C323, C369, and C371, integrates the charge pump output to produce the DC turning voltage for the VCO. One parasitic pole, consisting of RF chokes L306/L318, prevent modulation of the VCOs by the 5.00kHz or
6.25kHz reference energy remaining at the output of the loop filter. Direct FM is obtained for modulating frequencies outside the PLL bandwidth by applying the CTCSS/DCS signals and the pre­emphasized, limited microphone audio to the VCO modulation circuit. The modulation circuit consists of R347 and Q329.

7.3.6 Transmitter Section

7.3.6.1 RF Power Amplifier
After the PTT is pressed, the +5VTX-B line switches to approximately 5V. Q309 is turned on, enabling transmit VCO. The VCO buffer, pre-driver, driver and power amplifier are biased on by Q201. Q201 is biased on by the +5VTX-B line switching to 5V. RF output from the transmit VCO(Q325) is applied to the VCO output buffer Q308. Output from Q308 feeds the buffer Q414. The output signal from Q414 feeds the pre-driver amplifier Q413, and feeds the driver amplifier Q412, whose output from the driver stage feeds the final RF power amplifier Q411 to produce the rated output power of 5 watts. The final output is feed to a low-pass filter (C446-C448, C451, C452, L418, and L419) and then to the transmit/receive switch Q410. RF power is then fed to the antenna via the output low-pass filter consisting of C440-C445, L415, and L416.
7.3.6.2 Antenna Switching
Switching of the antenna between the transmitter and the receiver is accomplished by the antenna transmit/receive switch consisting of diodes Q409 and Q410. In the transmit mode, switched TX B+ is applied through R419 and RF choke L417, hard forward biasing the two diodes on Q410, thus permitting the flow of RF power from the output of the low-pass filter. L414 and C445 isolate the receiver circuit from the transmitter power input.
Page 52
7-6
7.3.6.3 Power Control
Output power is controlled by the CPU (Q101), the D/A converter (Q121), the dual Op-Amp (Q419), which is used as a differential amplifier and comparator. Current is sensed by the voltage drop across R445. When the radio is in high power mode, this voltage is compared to the D/A converter voltage at 5-watt. When the radio is in low power mode, this voltage is compared to the D/A converter voltage at 1-watt. The power output is then reduced or increased by varying the applied voltage to the gate of the power amplifier Q411 and Q412.
7.3.6.4 Transmitter Audio Circuits
The transmitter audio circuits consist of the audio processing circuits, the CTCSS circuits and the DCS circuits.
7.3.6.4.1 Audio Processing
Transmit speech audio is provided by either the internal electric microphone M101 or the external microphone. The audio is pre-emphasized by 6dB per octave by C615 and R655, and then its signal is amplified. The microphone audio is directed to amplifier Q602B, Q602A and low-pass filter Q602C and Q602D. Q602A has limiting function. The modulation adjustment is done by Pot RV601, and directed to a four-pole active low-pass filter. The resulting signal is then limited, and is directed to a low pass filter (18dB per octave roll-off above 3KHz). The audio is then directed through the 25KHz/
12.5KHz channel spacing SW Q601 to varactor diode Q329 in transmit VCO. By varying the voltage on the varactor diode Q329 at an audio rate, VCO output is frequency-modulated.

: Theory of Operation
7.3.6.4.2 CTCSS Tone Encoder / Digital Code Squelch (DCS) Encoder
CTCSS signals and DCS signals are synthesized by CPU Q101 and appear as pulse waveform on I/ O line Pin 7. This I/O line is connected to a digital-to-analog converter network (consisting of C136, C173, R150, R177 and R182), which produces a pseudo-sine wave at its output. The waveform is smoothed by low pass filters Q610B to produce an acceptable sine wave output. The CTCSS tone signal is adjusted to the proper level by RV602.

7.3.7 Receiver Section

7.3.7.1 Receiver Front End
In the receive mode, the RF signal enters thorough the antenna, then through the low-pass filter C439-C445, and L414-L416. The diodes Q409 and Q410 are biased off, so that the output of the low-pass filter is coupled (C437, C438, L413 and R418) to the first band-pass filter C401-C406, C408-C410, L401, L402, PCB_L1, Q401, R401, and to the Front End RF overload protection diode pair Q403. The signal from the band-pass filter is directed to the input of the RF amplifier Q404. The output of the RF amplifier is sent to three stages of band-pass filters, consisting of C415-C429,
C486, L404-L406, Q405 and R410. The output from the band-pass filter is directed to the mixer’s Q407/L407.
7.3.7.2 Local Oscillator (LO)
The Receive VCO (C344-C351, L302, L305, L306, L312-L314, Q311, and Q324) provides the LO signal. The VCO is running at 45.1 MHz above the desired receive frequency and is applied to output Buffer Q308/Q416. The output of the buffer is sent through the low-pass filter C430, C431, L409, and to the mixer Q407/L408.
August 30, 2002 99R85452E01-O
Page 53
VHF Band Information
: Theory of Operation 7-7
7.3.7.3 Mixer
The mixer is a DBM type (L407, Q407, L408). The mixer LO frequency is 45.1 MHz above the desired receiver frequency. When the receiver frequency is present, the mixer output will be a
45.1MHz signal. The mixer output is peaked for 45.1MHz at L410, C432 and R413, and the signal is filtered by crystal filter F402 and amplified by Q408 before being sent to IF IC Q506. The 45.1MHz IF signal and LO frequency of 44.645 MHz (X501) are mixed in Q506. The 455kHz ceramic filter, F501 or F502, filters the second mixer’s output. The resulting signal is the second IF signal. The mixer’s output is then fed to the internal limiting amplifier, and consequently to the FM decoder.
7.3.7.4 FM Detector and Squelch
The FM detector output is used for squelch, decoding tones and audio output. The squelch amplifier is inside of Q506, and its output is fed to an internal rectifier and squelch detector. The output on Q506 Pin 14 signals the CPU Q101 with a low (~0V) to unmute the radio. The audio is unmuted by the CPU Q101 Pin 41 switching to a high (5V), thus biasing on Q503. The audio is then routed to the audio amplifier Q702 via the volume control SW201.
7.3.7.5 Receiver Audio Circuit
The detector’s audio output also is fed to the tone (CTCSS and DCS) low-pass filter Q505A. Then the output of the low-pass filter is routed to the second stage filter Q505B. The output of Q505B is passed to Q505C. The output of Q505C is directed to the squaring circuit Q505D, and finally to the CPU Q101 Pin22 for decoding.
The detector output feeds the audio high-pass filter Q502. The output of the audio high-pass filter feeds the Volume Control SW201 (VOL). From the wiper arm on the Volume Control, the audio is routed to Pin 4, which is the input to the audio power amplifier Q702. The output of the audio power amplifier is routed through the earphone jack J701 to the internal speaker SP701.

7.3.8 Battery Section

The battery connects to the contact (CN201). The positive terminal of the battery connects to the ON/OFF Volume control switch (SW201), and the negative terminal connects to PWB ground. Low battery is detected by R127/R128 and voltage regulator Q204.
Battery voltage status is monitored by Pin 19 of the CPU Q101 through R127/R128. When the battery voltage goes below the threshold voltage, “LOW BATT" is displayed on LCD LC101. In the BATTERY SAVER Mode, the CPU Q101 generates a square wave signal on Pin 37. The signal’s duty cycle varies according to what the BATTERY SAVE TIMER is set. When the signal goes high (approximately 5 V), Q210 is biased off, and Q211 is cut off, thus turning the supply off to IF IC Q506.

8.3 Theory of Operation

8.3.1 General Information

Your radio has two printed circuit boards: the Controller board, and the Radio Frequency (RF) board. The Controller board contains the CPU/Control section. The RF board contains the VCO/Synthesizer section, Transmitter section, Receiver section, Transmitter Audio circuitry, Receiver Audio circuitry, and Battery section.

Figure 8-1.
The above figure illustrates the DC distribution throughout the radio board. A battery supplies power directly to the electronic on/off control. Radio power supply is triggered by the Power Switch (On/ Off/Volume control) and +SW B is distributed as show in the figure. Regulator output 5V is supplied to the CPU. +SW B continues to support the Audio Power AMP, 5V Regulator, TX Regulator until the radio is turned off.
The radio can be turned off on two ways:
1. Power Switch turned-off
2. Low Battery
When a low battery level is detected by the CPU, it stores the radio personality data to EEPROM before turning off the radio.

8.3.3 Power up Sequence

1. Power supply is turned on by the On/Off/Volume Control (Power Switch).
2. Power from battery is supplied to the regulator through the switch.
3. Output (5V) from the regulator is directed to the CPU (Q101).
4. Q105 resets the CPU (Q101).
5. The CPU loads radio personality data from EEPROM after the reset.

UHF Band Information
6. This personality data is used to initialize the radio.
7. The radio restores last power up state (i.e. state before the radio was turned-off).
8. Power is supplied to PLL circuitry.
9. Power is supplied to Rx and Rx VCO circuitry.
10. CPU sends data to PLL circuitry. If LOCK status is confirmed, radio continues the power-up
11. If the Rx audio level is less than the pre-programmed squelch level, and other unmuting

sequence. Otherwise, PLL ERR is displayed.
conditions are met, the radio will open squelch.

8.3.4 CPU / Control Section

When the radio is turned ON, the CPU (Q101) reads the radio status from the EEPROM Q114. It also monitors the keypad, the PTT line and other inputs such as the squelch detect, etc. continuously. When there is a channel change, the CPU sends the correct frequency information to the synthesizer via pins 1, 2 and 89. The CPU is clocked by the 8.388608MHz oscillator, which is composed of X101, C101, C106, and R158.

8.3.5 VCO / Synthesizer Section

This section consists of the Temperature-Compensated Crystal Oscillator(TCXO), Voltage Controlled Oscillator(VCO), Synthesizer and the Loop Filter. These circuits are found on the RF board.
8.3.5.1 Temperature-Compensated Crystal Oscillator (TCXO)
The reference oscillator is a temperature compensated crystal-controlled, Pierce type circuit. It utilizes a logic gate within Q323 as a gain element. C335 is used to adjust the oscillator on frequency (14.4MHz) at room temperature (22°C). Temperature variations cause resistance changes in thermistor R330 and R567, which is on the base of Q320, thus varying the voltage applied to varactor Q322. This changes the impedance across crystal X301 in a manner complementary to the temperature drift characteristic of the crystal. In this way, the reference oscillator is held within the specified ±2.5 PPM from -30 to +60°C.
8.3.5.2 Voltage-Controlled Oscillators
Only one of the VCOs runs at a time, which is controlled by Q317 and Q101. The receive VCO consists of C311, C314-C316, C913, C940, L302-L306, Q311 and Q302. This VCO oscillates at 45.1 MHz above the programmed receive frequency. The VCO’s oscillating frequency is tuned by the varactor Q311. The tuning voltage is supplied from the output of the Loop Filter. The output of the VCO is AC coupled (C311) to the buffer Q308. The output of the VCO buffer Q308 is AC coupled (C308) to the synthesizer and the output buffer Q416 respectively.
When the PTT is pressed, Q101 pin36 goes low (approx. 0V) disabling the receive VCO by the Q317 and biases on Q916 to enable the transmitter VCO. The transmitter VCO consists of C340, C935- C937, L308-L310, Q303, Q921 and Q922. This VCO oscillates on the programmed transmit frequency. The VCO’s oscillating frequency is tuned by the varactor Q922. The tuning voltage is supplied from the output of the Loop Filter. The transmit voltage controlled oscillator is directly frequency-modulated and operates on the carrier frequency. The synthesizer is tuned in 5.00kHz or
6.25kHz steps.

8.3.5.3 Synthesizer
The frequency synthesizer is a large-scale monolithic synthesizer integrated circuit Q323. The synthesizer IC contains a dual modulus prescaler, programmable divide-by-N counter, prescale control (swallow) counter, reference oscillator, reference divider, phase detector, charge pump and lock detector. Also, included in Q323 are shift registers and control circuits for frequency controls and general device control.
RF output from the active VCO is AC coupled to the synthesizer Q323 prescaler input at Pin 8. The divide counter chain in Q323, consisting of the dual-modulus prescaler, swallow counter and programmable counter, divides the VCO signal down to a frequency very close to 5.00kHz or
6.25kHz which is applied to the phase detector. The phase comparator compares the phase with the
5.00kHz or 6.25kHz reference signal from the reference divider and drives the external charge pump (Q314, Q315 and Q316). The synthesizer unlock detector circuit prevents the operation of the transmitter and receiver, when the phase lock loop (PLL) is unlocked. The following discussion assumes the unit has been placed in the transmit mode. Q323 lock detector Pin 7 goes high when the PLL is locked. This high level is applied to Pin 25 of the CPU Q101. A software timing routing brings the RX/TX line low (Pin 36 of Q101). With the RX/TX line goes low, Q209 is cut off and Q208 is biased on passing +5VTX-B to Q202; it biases on Q201 to pass switched TX-B to the transmitter amplifier string which enables transmission.
When the PLL is unlocked, the lock detector at Q323 Pin 7 will begin pulsing low. A RC circuit converts this low pulse to a low level for the CPU. The CPU then changes the RX/TX line to a high, thus signaling the other transistor switches to drive Q201 into cutoff, which disables transmission. Therefore, the transmitter remains disabled while the loop remains out of lock, and “PLL ERR” is displayed.

8.3.5.4 Loop Filter
The Loop Filter, a passive lead-lag filter consisting of R314-R317, R356, C323, C369, and C371, integrates the charge pump output to produce the DC turning voltage for the VCO. One parasitic pole, consisting of RF chokes L306 and L310, prevent modulation of the VCOs by the 5.00kHz or
6.25kHz reference energy remaining at the output of the loop filter. Direct FM is obtained for modulating frequencies outside the PLL bandwidth by applying the CTCSS/DCS signals and the pre­emphasized, limited microphone audio to the VCO modulation circuit. The modulation circuit consists of R929 and Q921.

8.3.6 Transmitter Section

8.3.6.1 RF Power Amplifier
After the PTT is pressed, the +5VTX-B line switches to approximately 5V. Q916 is turned on, enabling transmit VCO. The VCO buffer, pre-driver, driver and power amplifier are biased on by Q201. Q201 is biased on by the +5VTX-B line switching to 5V. RF output from the transmit VCO(Q303) is applied to the VCO output buffer Q308. Output from Q308 feeds the buffer Q414. The output signal from Q414 feeds the pre-driver amplifier Q413, and feeds the driver amplifier Q412, whose output from the driver stage feeds the final RF power amplifier Q411 to produce the rated output power of 5 watts. The final output is feed to a low-pass filter (C435-438, C491-C493, L418, and L430) and then to the transmit/receive switch Q410. RF power is then fed to the antenna via the output low-pass filter consisting of C439-C444, C475, L414, L415 and L416.
8.3.6.2 Antenna Switching
Switching of the antenna between the transmitter and the receiver is accomplished by the antenna transmit/receive switch consisting of diodes Q409 and Q410. In the transmit mode, switched TX B+ is applied through R417 and RF choke L417, hard forward biasing the two diodes on Q410, thus permitting the flow of RF power from the output of the low-pass filter. L419 and C433 isolate the receiver circuit from the transmitter power input.

Page 85
UHF Band Information
: Theory of Operation 8-7
8.3.6.3 Power Control
Output power is controlled by the CPU (Q101), the D/A converter (Q121), the dual Op-Amp (Q419), which is used as a differential amplifier and comparator. Current is sensed by the voltage drop across R442. When the radio is in high power mode, this voltage is compared to the D/A converter voltage at 5-watt. When the radio is in low power mode, this voltage is compared to the D/A converter voltage at 1-watt. The power output is then reduced or increased by varying the applied voltage to the gate of the power amplifier Q411 and Q412.
8.3.6.4 Transmitter Audio Circuits
The transmitter audio circuits consist of the audio processing circuits, the CTCSS circuits and the DCS circuits.
8.3.6.4.1 Audio Processing
Transmit speech audio is provided by either the internal electric microphone M101 or the external microphone. The audio is pre-emphasized by 6dB per octave by C615 and R655, and then its signal is amplified. The microphone audio is directed to amplifier Q602B, Q602A and low-pass filter Q602C and Q602D. Q602A has limiting function. The modulation adjustment is done by Pot RV601, and directed to a four-pole active low-pass filter. The resulting signal is then limited, and is directed to a low pass filter (18dB per octave roll-off above 3KHz). The audio is then directed through the 25KHz/
12.5KHz channel spacing SW Q601 to varactor diode Q329 in transmit VCO. By varying the voltage on the varactor diode Q329 at an audio rate, VCO output is frequency-modulated.
8.3.6.4.2 CTCSS Tone Encoder / Digital Code Squelch (DCS) Encoder
CTCSS signals and DCS signals are synthesized by CPU Q101 and appear as pulse waveform on I/ O line Pin 7. This I/O line is connected to a digital-to-analog converter network (consisting of C136, C173, R150 and R182), which produces a pseudo-sine wave at its output. The waveform is smoothed by low pass filters Q610B to produce an acceptable sine wave output. The CTCSS tone signal is adjusted to the proper level by RV602.

8.3.7 Receiver Section

8.3.7.1 Receiver Front End
In the receive mode, the RF signal enters thorough the antenna, then through the low-pass filter C439-C445, and L414-L416. The diodes Q409 and Q410 are biased off, so that the output of the low-pass filter is coupled to the first band-pass filter C401-C409, L401, L402, Q401, Q402, R401, R402 and to the Front End RF overload protection diode pair Q403. The signal from the band-pass filter is directed to the input of the RF amplifier Q404. The output of the RF amplifier is sent to three stages of band-pass filters, consisting of C413-C417, C419-C422, C487, L405-L407, Q405, Q406 and R408-R410. The output from the band-pass filter is directed to the mixer’s Q407, L408 and L409.
8.3.7.2 Local Oscillator (LO)
The Receive VCO (C311, C314 -C316, C913, C940, L302- L306, L312-L314, Q311, and Q302) provides the LO signal. The VCO is running at 45.1 MHz above the desired receive frequency and is applied to output Buffer Q308 and Q416. The output of the buffer is sent through the low-pass filter C424, C425, L410, L411 and to the mixer Q407, L408 and L409.
Page 86
8-8
8.3.7.3 Mixer
The mixer is a DBM type (L408, L409, Q407). The mixer LO frequency is 45.1 MHz above the desired receiver frequency. When the receiver frequency is present, the mixer output will be a
45.1MHz signal. The mixer output is peaked for 45.1MHz at L412, C426 and R412, and the signal is filtered by crystal filter F402 and amplified by Q408 before being sent to IF IC Q506. The 45.1MHz IF signal and LO frequency of 44.645 MHz (X501) are mixed in Q506. The 455kHz ceramic filter, F501 or F502, filters the second mixer’s output. The resulting signal is the second IF signal. The mixer’s output is then fed to the internal limiting amplifier, and consequently to the FM decoder.
8.3.7.4 FM Detector and Squelch
The FM detector output is used for squelch, decoding tones and audio output. The squelch amplifier is inside of Q506, and its output is fed to an internal rectifier and squelch detector. The output on Q506 Pin 14 signals the CPU Q101 with a low (~0V) to unmute the radio. The audio is unmuted by the CPU Q101 Pin 41 switching to a high (5V), thus biasing on Q503. The audio is then routed to the audio amplifier Q702 via the volume control SW201.
8.3.7.5 Receiver Audio Circuit
The detector’s audio output also is fed to the tone (CTCSS and DCS) low-pass filter Q505A. Then the output of the low-pass filter is routed to the second stage filter Q505B. The output of Q505B is passed to Q505C. The output of Q505C is directed to the squaring circuit Q505D, and finally to the CPU Q101 Pin22 for decoding.
UHF Band Information
: Theory of Operation
The detector output feeds the audio high-pass filter Q502. The output of the audio high-pass filter feeds the Volume Control SW201 (VOL). From the wiper arm on the Volume Control, the audio is routed to Pin 4, which is the input to the audio power amplifier Q702. The output of the audio power amplifier is routed through the earphone jack J701 to the internal speaker SP701.

8.3.8 Battery Section

The battery connects to the contact (CN201). The positive terminal of the battery connects to the ON/OFF Volume control switch (SW201), and the negative terminal connects to PWB ground. Low battery is detected by R127/R128 and voltage regulator Q204.
Battery voltage status is monitored by Pin 19 of the CPU Q101 through R127/R128. When the battery voltage goes below the threshold voltage, “LOW BATT” is displayed on LCD LC101. In the BATTERY SAVER Mode, the CPU Q101 generates a square wave signal on Pin 37. The signal’s duty cycle varies according to what the BATTERY SAVE TIMER is set. When the signal goes high (approximately 5 V), Q210 is biased off, and Q211 is cut off, thus turning the supply off to IF IC Q506.
