INTRODUCTION

SCOPE OF THIS MANUAL
This manual is intended for use by experienced techni­cians familiar with similar types of commercial grade com­munications equipment. It contains all required service in­formation for the equipment and is current as of this publica­tion date. Changes which may occur after publication are covered by either Service Bulletins or Manual Revisions, which are issued as required.

ORDERING REPLACEMENT PARTS

When ordering replacement parts or equipment informa­tion, the full part identification number should be included. This applies to all parts : components, kits, and chassis. If the part number is not known, include the chassis or kit number of which it is a part and a sufficient description of the required component, for proper identification.

PERSONAL SAFETY

The following precautions are recommended for personal safety :
•DONOT transmit if someone is within two feet (0.6
meter) of the antenna.
•DONOT transmit until all RF connectors are secure and
any open connectors are properly terminated.
• SHUT OFF this equipment when near electrical blasting
caps or while in an explosive atmosphere.
• All equipment should be properly grounded before
power-up for safe operation.
• This equipment should be serviced by only qualified
technicians.

PRE-INSTALLATION CONSIDERATIONS

1. UNPACKING
Unpack the radio from its shipping container and check for accessory items. If any item is missing, please contact KENWOOD immediately.
2. LICENSING REQUIREMENTS
Federal regulations require a station license for each radio installation (mobile or base) be obtained by the equipment owner. The licensee is responsible for ensuring transmitter power, frequency, and deviation are within the limits permitted by the station license.
Transmitter adjustments may be performed only by a licensed technician holding an FCC first, second or general class commercial radiotelephone operator’s license. There is no license required to install or operate the radio.
3. PRE-INSTALLATION CHECKOUT
3-1. Introduction
Each radio is adjusted and tested before shipment. However, it is recommended that receiver and transmitter operation be checked for proper operation before installation.
3-2. Testing
The radio should be tested complete with all cabling and accessories as they will be connected in the final installa­tion. Transmitter frequency, deviation, and power output should be checked, as should receiver sensitivity, squelch operation, and audio output. Signaling equipment operation should be verified.
4. PLANNING THE INSTALLATION
4-1. General
Inspect the vehicle and determine how and where the radio antenna and accessories will be mounted.
Plan cable runs for protection against pinching or crush­ing wiring, and radio installation to prevent overheating.
4-2. Antenna
The favored location for an antenna is in the center of a large, flat conductive area, usually at the roof center. The trunk lid is preferred, bond the trunk lid and vehicle chassis using ground straps to ensure the lid is at chassis ground.
2
GENERAL
4-3. Radio
The universal mount bracket allows the radio to be mounted in a variety of ways. Be sure the mounting surface is adequate to support the radio’s weight. Allow sufficient space around the radio for air cooling. Position the radio close enough to the vehicle operator to permit easy access to the controls when driving.
4-4. DC Power and wiring
1. This radio may be installed in negative ground electrical
systems only. Reverse polarity will cause the cable fuse
to blow. Check the vehicle ground polarity before
installation to prevent wasted time and effort.
2. Connect the positive power lead directly to the vehicle
battery positive terminal. Connecting the Positive lead to
any other positive voltage source in the vehicle is not
recommended.
3. Connect the ground lead directly to the battery negative
terminal.
4. The cable provided with the radio is sufficient to handle
the maximum radio current demand. If the cable must be
extended, be sure the additional wire is sufficient for the
current to be carried and length of the added lead.

5.
INSTALLATION PLANNING – CONTROL STATIONS
5-1. Antenna system
Control station. The antenna system selection depends on many factors and is beyond the scope of this manual. Your KENWOOD dealer can help you select an antenna system that will best serve your particular needs.
5-2. Radio location
Select a convenient location for your control station radio which is as close as practical to the antenna cable entry point. Secondly, use your system’s power supply (which supplies the voltage and current required for your system). Make sure sufficient air can flow around the radio and power supply to allow adequate cooling.

SERVICE

This radio is designed for easy servicing. Refer to the schematic diagrams, printed circuit board views, and alignment procedures contained in this manual.

3-1. Front-end RF Amplifier
The receive signal from the RX terminal (CN200) of the TX­RX unit (X57-703) is amplified by a transistor (Q200) and passes through the band-pass filter (L221, L222, L223) to remove unwanted signal.
The signal passing through the band-pass filter goes into the 1st mixer.
These band-pass filters are tuned to a desired frequency by variable capacitance diode (D200, D201, D202).

4. Transmitter System

4-1. Audio Band Circuit
The audio band circuit of the transmitter system consists of the following:
•Microphone mute switch (Q723)
• AGC (Automatic Gain Control) (Q715, Q716, IC719, D727, D728)
• Scrambler board switch (Q720)
The microphone mute switch (Q723) cuts off audio
signals from the external microphone.
The AGC (Q715, Q716, IC719, D727, D728) is an
amplifier that reduces gain automatically by greatly increasing the attenuation when the audio signal of a certain level or higher is present. It controls the gain so that the audio signal input to the CODEC IC (IC724) is not clipped.
If an optional scrambler board is installed, the switch
(Q720) adjusts the signal path so that the audio signal is fed to the CODEC IC through the scrambler board.
The audio signal is fed to the CODEC IC (base band
circuit) through the above path.
4-2. Base Band Circuit
The base band circuit of the transmitter system consists of the following:
• CODEC IC (IC724)
• DSP IC (IC715)
• LPF (Low-Pass Filter) (IC729)
• Summing amplifier (IC733)
• DAC (D/A Converter) (IC738)
• Amplifier (IC735)
The audio signal output from the base band circuit is converted to digital data of a sampling frequency of 48 kHz and a quantization resolution of 16 bits. This digital data is sent to the DSP IC (IC715), and voice signals of 300 Hz or lower and frequencies of 3 kHz or higher are cut off and an audio range 300 Hz to 3 kHz is extracted.
The audio signal is then pre-emphasized in FM mode and synthesized with the signals, such as QT and DQT, as required, and is then output from the CODEC IC. In APCO mode, the audio signal is converted to the C4FM base band signal and output from the CODEC IC. The DTMF and MSK base band signals are also generated by the DSP IC and output by the CODEC IC.
LPF (IC729) removes quantization noise from the base band signal output from the CODEC IC.
The summing amplifier (IC733) sets the base band signal level to the DAC input range.
The DAC (IC738) assigns the base band signal to the VCO (Q413, Q414, Q416) and VCXO (X400).
At this time, the level output according to the transmit carrier is fine-adjusted according to the modulation method of FM Wide, FM Narrow and APCO.

4-6. Temperature Protection Circuit : TK-5710 (B)
To prevent thermal destruction of the power module (IC2), this circuit reduces APC voltage when temperature of the power module (IC2) rises.
The CPU (IC703) detects temperature with a thermistor (TH1) and controls reference voltage to the APC circuit.

5. PLL Frequency Synthesizer

The PLL Frequency Synthesizer consists of the following components:
• VCXO (X400)
• VCO (Q413, Q414,Q416)
• Rheostat IC (IC401)
• PLL IC (IC400)
• Local switch (D435, D436)
5-1. VCXO (X400)
VCXO (X400) generates a reference frequency of 16.8 MHz for the PLL frequency synthesizer. This reference frequency is applied to pin 10 of the PLL IC (IC400).
The VCXO oscillation frequency is fine-adjusted by controlling the voltage applied to pin 1 of the VCXO with DAC (IC738). It is also controlled with pin 1 of the VCXO if the output from VCXO is modulated.
4-7. Temperature Protection Circuit : TK-5710H (B)
To prevent thermal destruction of the power module (IC1) and final amplifier (Q1,Q2), this circuit reduces APC voltage when temperature of the power module (IC1) and final amplifier (Q1,Q2) rises.
The CPU (IC703) detects temperature with the thermistor (TH1,TH2) and controls reference voltage to the APC circuit.
5-2. VCO
There is two RX VCOs (RX VCO 1, RX VCO 2) and a TX
VCO.
The RX VCO 1 (Q413) and RX VCO 2 (Q414) generate a 1st
local receive signal. The RX VCO 1 oscillation frequency is
185.95 to 204.9475 MHz and the RX VCO 2 oscillation frequency is 204.95 to 223.95 MHz.
The TX VCO (Q416) generates a transmit carrier. The TX
VCO oscillation frequency is 136 to 174 MHz.
The VCO oscillation frequency is determined by two systems of operation switching terminals "STR" and "VCO1/2" and two systems of voltage control terminals "C/V" and "ASSIST".
The operation switching terminals, "STR" and "VCO1/2", are controlled by the control lines (STR, VCO1/2) output from the CPU (IC703). When the STR logic is high and the VCO1/2 logic is high, the RX VCO 1 output a 1st local receive signal. When the STR logic is high and the VCO1/2 logic is low, the
29
TK-5710(B)/5710H(B
CIRCUIT DESCRIPTION
)
RX VCO 2 output a 1st local receive signal. When the STR logic is low, the TX VCO output a transmit carrier.
The voltage control terminals, "CV" and "ASSIST", are controlled by the PLL IC (IC400) and rheostat IC (IC401) and the output frequency changes continuously according to the applied voltage. For the modulation input terminal, "MOD", the output frequency changes according to the applied voltage. This is used to modulate the VCO output. "MOD" works only when " STR" is low.
5-3. Rheostat IC (IC401)
The rheostat IC (IC401) is connected to the VCO voltage control terminal, "ASSIST", and quickly controls the VCO oscillation frequency. However, its accuracy is low and the VCO frequency cannot be matched accurately with the desired transmit carrier or the 1st local receive signal.
The rheostat IC is controlled by the CPU (IC703) through the 3-line "PCS", "DAT", "CLK" serial bus.
5-4. PLL IC (IC400)
PLL IC compares the differences in phases of the VCO oscillation frequency and the VCXO reference frequency, returns the difference to the VCO CV terminal and realizes the "Phase Locked Loop" for the return control. This allows the VCO oscillation frequency to accurately match (lock) the
desired frequency.
When the frequency is controlled by the PLL, the frequency convergence time increases as the frequency difference increases when the set frequency is changed. To supplement this, the rheostat IC is used before control by the PLL IC to bring the VCO oscillation frequency close to the desired frequency. As a result, the VCO CV voltage does not change and is always stable at approximately 2 V.
The desired frequency is set for the PLL IC by the CPU (IC703) through the 3-line "EP", "DAT", "CLK" serial bus. Whether the PLL IC is locked or not is monitored by the CPU through the “UL” signal line. If the VCO is not the desired frequency (unlock), the "UL" logic is low.
5-5. Local Switch (D435, D436)
The connection destination of the signal output from the amplifier (Q419) is changed with the diode switch (D435) that is controlled by the transmission power supply, 8T, and the diode switch (D436) that is controlled by the receive power supply, 8R.
If the 8T logic is high, it is connected to a transmit-side pre-pre-drive amplifier (Q150). If the 8R logic is high, it passes through the local amplifier (Q210) and then is connected to a receive-side mixer (A400).
