INTRODUCTION
SCOPE OF THIS MANUALThis manual is intended for use by experienced techni-
cians familiar with similar types of commercial grade com-munications equipment. It contains all required service information for the equipment and is current as of this pub-lication 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 informa-tion, the full part identifi cation 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 suffi cient description of the required component for proper identifi cation.
PERSONNEL SAFETY
The following precautions are recommended for person-nel safety :• DO NOT transmit if someone is within two feet (0.6 me-
ter) of the antenna.• DO NOT 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 pow-
er-up for safe operation.• This equipment should be serviced by only qualified
technicians.
PRE-INSTALLATION CONSIDERATIONS
1. UNPACKINGUnpack the radio from its shipping container and check
for accessory items. If any item is missing, please contact KENWOOD immediately.
2. LICENSING REQUIREMENTSFederal regulations require a station license for each
radio installation (mobile or base) be obtained by the equip-ment owner. The licensee is responsible for ensuring trans-mitter 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 fi rst, 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. IntroductionEach radio is adjusted and tested before shipment. How-
ever, it is recommended that receiver and transmitter opera-tion be checked for proper operation before installation.
3-2. TestingThe radio should be tested complete with all cabling and
accessories as they will be connected in the fi nal installa-tion. Transmitter frequency, deviation, and power output should be checked, as should receiver sensitivity, squelch operation, and audio output. Signalling equipment operation should be verifi ed.

4. PLANNING THE INSTALLATION
4-1. GeneralInspect the vehicle and determine how and where the
radio antenna and accessories will be mounted.Plan cable runs for protection against pinching or crush-
ing wiring, and radio installation to prevent overheating.
4-2. AntennaThe 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.
4-3. RadioThe 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 suffi cient 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 wiring1. 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 instal-lation 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 suffi cient to handle the maximum radio current demand. If the cable must be extended, be sure the additional wire is suffi cient for the current to be carried and length of the added lead.
5. INSTALLATION PLANNING – CONTROL STATIONS
5-1. Antenna systemControl 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 sys-tem that will best serve your particular needs.
5-2. Radio locationSelect 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 suffi cient air can fl ow around the radio and pow-er supply to allow adequate cooling.
SERVICE
This radio is designed for easy servicing. Refer to the schematic diagrams, printed circuit board views, and align-ment procedures contained in this manual.

2. Receiver System
The receiver is a double conversion superheterodyne.The frequency confi guration is shown in Figure 1.
2-1. Front-end RF Amplifi er An incoming signal from the antenna is applied to an RF
amplifier (Q506) after passing through a transmit/receive switch circuit (D302, D303, D304 and D305), BPF (L517, L518 and varactor diodes: D509, D510) and the Notch fi lter (L519 and varactor diode: D511). The Notch fi lter function is eliminate the image frequency.
After the signal is amplifi ed (Q506), the signal is fi ltered by a BPF (L511, L512, L513 and varactor diodes : D505, D506, D508) to eliminate unwanted signals before it is passed to the fi rst mixer.
The voltage of these diodes are controlled by tracking the MCU (IC702) center frequency of the bandpass filter. (See Figure 2)
2-2. First Mixer The signal from the RF amplifi er is heterodyned with the
fi rst local oscillator signal from the PLL frequency synthe-sizer circuit at the fi rst mixer (Q504) to create a 38.85MHz fi rst intermediate frequency (1st IF) signal. The fi rst IF signal is then fed through one pair of monolithic crystal fi lters (MCF: XF500) to further remove spurious signals.

IC500 (FM processing IC). The signal is heterodyned again with a second local oscillator signal within IC500 to create a 450kHz second IF signal. The second IF signal is then fed through a 450kHz ceramic fi lter (Wide: CF500, Narrow: CF501) to further eliminate unwanted signals before it is amplifi ed and demodulatedby the quadrature detector with the ceramic discriminator (CD500).

3. Transmitter System
3-1. OutlineThe transmitter circuit produces and amplifies the de-
sired frequency directly. It FM-modulates the carrier signal by means of a varicap diode.
3-2. Power Amplifi er CircuitThe transmit output signal from the VCO passes through
the transmission/reception selection diode (D719) and am-plifi ed by Q300. The amplifi ed signal goes to the RF power module (IC301) through a low-pass fi lter. The low-pass fi lter removes unwanted high-frequency harmonic components, and the resulting signal goes through the antenna terminal.
3-3. APC CircuitThe automatic transmission power control (APC) circuit
detects part of a fi nal amplifi er output with a coupler circuit and applies a voltage to IC300. IC300 compares the APC control voltage (PC) generated by the baseband IC (IC701) and DC amplifi er (IC501) with the detection output voltage. IC300 generates the voltage to control IC301 and stabilizes transmission output.
The APC circuit is confi gured to protect over current of Q300 and IC301 due to fl uctuations of the load at the anten-na end and to stabilize transmission output at voltage and temperature variations.

4. PLL Frequency Synthesizer
The PLL circuit generates the fi rst local oscillator signal for reception and the RF signal for transmission.
4-1. PLL CircuitThe frequency step of the PLL circuit is 5 or 6.25kHz.A 19.2MHz reference oscillator signal is divided at IC1 by
a fi xed counter to produce the 5 or 6.25kHz reference fre-quency. The voltage controlled oscillator (VCO) output signal is buffer amplifi ed by Q9, then divided by a programmable counter in IC1.
The divided signal is compared in phase with the 5 or 6.25kHz reference signal in the phase comparator in IC1. The output signal from the phase comparator is filtered
through a low-pass fi lter and passed to the VCO to control the oscillator frequency.
4-2. VCO CircuitThe operating frequency is generated by Q6 in transmit
mode and Q4 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator to the varactor diodes (D4 in transmit mode and D5 in receive mode) and assist voltage to the (D6, D8 and D9 in transmit mode and D7, D10 and D11 in receive mode).
The TX/RX pin is set high in receive mode causing Q5 to turn off, and turn Q7 on. The TX/RX pin is set low in trans-mit mode. The outputs from Q4 and Q6 are amplifi ed by Q9 and sent to the RF amplifi ers.

4-3. Unlock CircuitDuring reception, the 9RC signal goes high, the 9TC sig-
nal goes low, and Q711 turns on. Q713 turns on and a volt-age is applied to the collector (9R). During transmission, the 9RC signal goes low, the 9TC signal goes high and Q712 turns on. Q714 turns on and a voltage is applied to 9T.
The MCU in the control unit monitors the PLL (IC1) LD signal directly. When the PLL is unlocked during transmis-sion, the PLL LD signal goes low. The MCU detects this signal and makes the 9TC signal low. When the 9TC signal goes low, no voltage is applied to 9T, and no signal is trans-mitted.

5-2. Display CircuitThe MCU (IC702) controls the 7-segment LED Display
and LEDs. When power is on, the MCU will use the MBL line to
control the key backlight LEDs.When the transceiver is busy, the GLED line goes high,
Q1 turns on and the green LED (D23) lights after Q4 turns on. In transmit mode, the RLED line goes high, Q2and Q8 turn on and the red LED (D23) lights.
BLED will be set high when the function select (FPU set-ting) is on, Q6 turns on and the blue LED (D22) lights.
The dimmer function is controlled by the switch (Q5). The LED driver (IC1) controls the functions of the 7-segment LED through the LEDI, LECE, LECL, LELH lines from the MCU.

5-3. Key Matrix CircuitThe TK-8302 front panel has function keys. Each of them
is connected to a cross point of a matrix of the KMI1 to KMO3 ports of the MCU. The KMO1 to KMO3 ports are al-ways high, while the KMI1 to KMI3 ports are always low.
The MCU monitors the status of the KMI1 to KMO3 ports. If the state of one of the ports changes, the MCU as-sumes that the key at the matrix point corresponding to that port has been pressed.

6. Signaling Circuit
6-1. Encode
■ Low-speed data (QT, DQT)Low -speed data is output from pin 1 (LSDO) of the MCU
(IC702). The signal passes through a low-pass CR fi lter. The signal is mixed with the audio signal and goes to the VCO and TCXO (X1) modulation input after signal processing in the baseband IC (IC701).
■ High-speed data (2-tone)High-speed data (HSD) is output from pin 2 (HSDO) of
the MCU. The signal passes through a low-pass CR fi lter. TX devia-
tion making an adjustment by MCU is applied to the base-band IC (IC701). The signal is mixed with the audio signal and goes to the VCO and TCXO.
The RX tone is audio output of the baseband IC (IC701) at the same time to audio power amplifi er and then to the speaker.

■ MSK / DTMFMSK and DTMF signal is self generated by the baseband
IC (IC701). The TX deviation adjustment is done by the output gain
of the baseband IC (IC701), and is routed to the VCO. When encoding MSK/DTMF, the microphone-input signal is muted.
6-2. Decode
■ Low-speed data (QT, DQT)The demodulated signal from the FM IC (IC500) will input
to the baseband IC (IC701) to remove frequencies of 300Hz or more.
The signal is input to pin 88 (LSDI) of the MCU. The MCU digitizes this signal, performs processing such as DC restoration, and decodes the signal.

■ High-speed data (2-tone)The demodulated signal from the FM IC (IC500) is am-
plifi ed by the baseband IC and passes through a high-pass fi lter to remove frequencies of 3kHz or more. The MCU digi-tizes this signal and decodes the signal after receiving the signal at pin 87 (HSDI).
■ MSK/ DTMFThe demodulated signal from the FM IC (IC500) will in-
put to the baseband IC (IC701), then the baseband IC will decode and send the decoded information to MCU by the data line.
The MCU then processes the decoded information.

7. Power Supply Circuit
When the power switch on the display unit is pressed, the power port on the display unit which is connected to port 17 (POWER), goes low, then port 52 (SBC) goes high, Q719 turns on, SB switch (Q720) turns on and power (SB) is supplied to the transceiver.
When the DC power is supplied to the transceiver, the voltage regulator IC (IC707, IC706) and supply into the MCU VDD and reset the voltage detect IC (IC709). IC709 will generate signal (RESET) into the reset terminal on the MCU (IC702) to carry out a power ON reset. Also, MCU (IC702) is checking on port 91 (BATT). If DC power is less than about 8.5V, the transceiver is unable to power on.
When the DC power voltage deceases from normal volt-age, the INT voltage detector IC (IC708) will set to high on MCU port 18 (INT). If B line becomes less than about 8.5V, MCU will send the backup data to EEPROM (IC703) and go into STOP mode.
This circuit has an overvoltage protection circuit. If a DC voltage of 16V or higher is applied to the base of Q710, this voltage turns Q710 on and sets port 18 (INT) to low. As a re-sult port 78 (SBC) is low, and turns Q719 and Q720 (SB) off.
