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. Signalling equipment operation should be verified.
TK-7302/7302(V)/7302H/7302H(V) GENERAL 4. PLANNING THE INSTALLATION 4-1. General
5. INSTALLATION PLANNING – CONTROL STATIONS 5-1. Antenna system
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.
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.
4-2. Antenna
5-2. Radio location
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.
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.
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.
SERVICE This radio is designed for easy servicing. Refer to the schematic diagrams, printed circuit board views, and alignment procedures contained in this manual.
NOTE If you do not intend to use the 3.5-mm jack for the external speaker, fit the supplied speaker-jack cap to stop dust and sand from getting in.

2-4. Wide/Narrow Switching Circuit The Wide port (pin 99) and Narrow port (pin 98) of the MCU is used to switch between ceramic filters. When the Wide port is high, the ceramic filter switch diodes (D500, D501) cause CF500 to turn on to receive a Wide signal. When the Narrow port is high, the ceramic filter switch diodes (D500, D501) cause CF501 to turn on to receive a Narrow signal.

3-2. Power Amplifier Circuit CF501 (Narrow)
The transmit output signal from the VCO passes through the transmission/reception selection diode (D719) and amplified by Q300. The amplified signal goes to the RF power module (IC301) through a low-pass filter. The lowpass filter removes unwanted high-frequency harmonic components, and the resulting signal goes through the antenna terminal.

The automatic transmission power control (APC) circuit detects part of a final amplifier 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 amplifier (IC501) with the detection output voltage. IC300 generates the voltage to control IC301 and stabilizes transmission output. The APC circuit is configured to protect over current of Q300 and IC301 due to fluctuations of the load at the antenna end and to stabilize transmission output at voltage and temperature variations.

TK-7302/7302(V)/7302H/7302H(V) CIRCUIT DESCRIPTION through a low-pass filter and passed to the VCO to control the oscillator frequency.
4. PLL Frequency Synthesizer The PLL circuit generates the first local oscillator signal for reception and the RF signal for transmission.
4-2. VCO Circuit The 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 and D14 in transmit mode and D5 and D13 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 transmit mode. The outputs from Q4 and Q6 are amplified by Q9 and sent to the RF amplifiers.
4-1. PLL Circuit The frequency step of the PLL circuit is 10 or 12.5kHz. A 19.2MHz reference oscillator signal is divided at IC1 by a fixed counter to produce the 10 or 12.5kHz reference frequency. The voltage controlled oscillator (VCO) output signal is buffer amplified by Q9, then multiplied by using a doubler and divided by a programmable counter in IC1. The divided signal is compared in phase with the 10 or 12.5kHz reference signal in the phase comparator in IC1. The output signal from the phase comparator is filtered

5. Control Circuit The MCU carries out the following tasks: 1) Controls the WIDE, NARROW, TX/RX outputs. 2) Controls the Baseband IC (IC701). 3) Controls the PLL (IC1). 4) Controls the display unit. IC1 PLL PLLE PLDT PLCK UL
During reception, the 9RC signal goes high, the 9TC signal goes low, and Q711 turns on. Q713 turns on and a voltage 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 transmission, 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 transmitted. 9C Q714 SW

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 filter. 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 filter. TX deviation making an adjustment by MCU is applied to the baseband 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 amplifier and then to the speaker. LSDO QT/DQT IC702 MCU

Memory circuit
The 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 Q7 turns on. In transmit mode, the RLED line goes high, Q2 and Q8 turn on and the red LED (D23) lights. BLED will be set high when the function select (FPU setting) 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 Circuit The TK-7302 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 always 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 assumes that the key at the matrix point corresponding to that port has been pressed.
MSK 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.

TK-7302/7302(V)/7302H/7302H(V) CIRCUIT DESCRIPTION ■ High-speed data (2-tone)
7. Power Supply Circuit
The demodulated signal from the FM IC (IC500) is amplified by the baseband IC and passes through a high-pass filter to remove frequencies of 3kHz or more. The MCU digitizes this signal and decodes the signal after receiving the signal at pin 87 (HSDI).
■ MSK/ DTMF The demodulated signal from the FM IC (IC500) will input to the baseband IC(IC701), then the baseband IC will decode and send the decoded information to the MCU by the data line. The MCU then processes the decoded information.

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, voltage regulator IC (IC707, IC706) will 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 voltage, 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 result port 78 (SBC) is low, and turns Q719 and Q720 (SB) off.
