TK-7108H GENERAL 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.
PERSONNEL SAFETY The following precautions are recommended for personnel safety : • DO NOT transmit if someone is within two feet (0.6 meter) 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 powerup for safe operation. • This equipment should be serviced by only qualified technicians.
PRE-INSTALLATION CONSIDERATIONS
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.
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.
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.
1. UNPACKING
4-4. DC Power and wiring
Unpack the radio from its shipping container and check for accessory items. If any item is missing, please contact KENWOOD immediately.
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.
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.

TK-7108H OPERATING FEATURES • Group If Group has been programmed onto a key, press the Group key to select the second group of channels. While active, the LED beside the key lights. At this time, press a key from 1 to 4 select a channel from 5 to 8. To return to channels 1 through 4, press the Group key again. Note : You cannot use the Group function while operating in Emergency mode.
4. Scan Operating ■ SCAN start condition Two or more channels must be added to all channels that can be scanned. The transceiver must be in normal receive mode (PTT off). When you activate the key programmed to the scan ON/ OFF function, the scan starts. The indicator next to the programmed key LED blinks.
■ Scan stop condition The scan stops temporarily if the following conditions are satisfied. 1) A carrier is detected, then QT/DQT matches on channels for which receive the QT/DQT is set by the programming software. 2) A carrier is detected on the channels for which receiving QT/DQT is not set by the programming software or when the monitor (signalling cancel) function is activated.
■ Revert channel The revert channel is used to transmit during scanning and set by the programming software (KPG-70D). 1) Selected channel The transceiver reverts to the channel before scanning or the channel that you changed during scan. 2) Selected with talkback The transceiver reverts to the selected channel prior to scan initiation. However, if a call is received on a channel other then the selected channel and PTT is pressed before scanning resume, the transceiver “talks back” on the current receive channel.
■ Time-out timer The time-out timer can be programmed in 30 seconds increments from 30 seconds to five minutes and off. If the transmitter is transmitted continuously for longer than the programmed time, the transmitter is disabled and a warning tone sounds while the PTT button is held down. The warning tone stops when the PTT button is released.
■ PTT ID PTT ID provides a DTMF ANI or MSK ID to be sent with every time PTT (connect ID at beginning of transmission, disconnect ID at end of transmission, or both). You can program PTT ID “on” or “off” for each group channel (DTMF). The contents of ID are programmed for each transceiver. The transceiver is capable to have ID. The format is DTMF. The timing that the transceiver sends ID is programmable. BOT : Connect ID is sent on beginning of transmission. EOT : Disconnect ID is sent on end of transmission. Both : Connect ID is sent on beginning of transmission and disconnect ID is sent on end of transmission. There is also “PTT ID” setting for each channel.
■ Off hook decode If the Off hook decode function has been enabled, removing and replacing the microphone on the hook has no effect for decoding QT/DQT and option signalling.
■ “TOT” pre-alert The transceiver has “TOT” pre-alert timer. This parameter selects the time at which the transceiver generates “TOT” pre-alert tone before “TOT” is expired. “TOT” will be expired when the selected time passes from a TOT pre-alert tone.
■ “TOT” re-key time The transceiver has “TOT” re-key timer. This timer is the time you can not transmit after “TOT” exceeded. After “TOT” re-key time expired you can transmit again.
■ Scan end
■ “TOT” reset time
When you press the key programmed to the scan function during scan mode, the scan ends. The indicator next to the programmed key LED turns off.
The transceiver has “TOT” reset timer. This timer is the minimum wait time allowed during a transmission that will reset the “TOT” count. “TOT” reset time causes the “TOT” to continue even after PTT is released unless the “TOT” reset timer has expired.
■ Temporary delete It is possible to delete channel temporary during scan. When scan stops on unnecessary channel for example by interference of the other party, activate the delete function (for example press and hold the key for approximately one second), then that channel is deleted temporarily and scan restart immediately. The temporary deleted channels return to pre-set delete/ add channels, when the transceiver is turned off or the scan function is switched off.

5. Details of Features
■ Clear to transpond The transceiver waits the transpond of DTMF if channel is busy until channel open. This feature prevents the interference to other party.
TK-7108H OPERATING FEATURES ■ Stun
6. Option Signalling (DTMF) Built-in DTMF decoder is available for option signalling. It is possible to use individual call, group call, Stun. If the option signalling matches, a predetermined action will occur. If option signalling matches on a channel is set up with option signalling, the channel LED will flash and option signalling will be released. The transpond or alert tone will sound. While option signalling matches (or if option signalling is deactivated when you are transmitting), you can mute or unmute QT/DQT/Carrier.
■ SP Unmute You can select the type of SP Unmute system for each channel. The selection is as follows. Carrier, QT/DQT: Channel with this option will not check ID Code in order to open its speaker. Carrier+DTMF, QT/DQT+DTMF: Channel that is set with this option will have to check for ID Code in order to open its speaker. Default: Carrier, QT/DQT. SP unmute

■ Auto Reset If option signalling matches a group set up with option signalling, option signalling is released. After matching option signalling, option signalling will temporarily reset automatically.
If the stun code matches, a predetermined action will occur. Whether option signalling is activated or not, when stun matches on any channel, the transceiver will become TX inhibited or TX/RX inhibited. While stun is active, if the stun code + “#” code is received, stun will deactivate. When stun matches, transpond will function. Alert will not be output.
7. Audible User Feedback Tones The transceiver outputs various combinations of tones to notify the user of the transceiver operating state. Refer to the help file on the KPG-70D, regarding the functions that are not listed below.
■ Stun on tone When a stun code is received, transpond tone sounds.
■ Stun off tone When a stun release code is received, transpond tone sounds.
■ Group call tone Sounds when a group call with the correct DTMF option signalling is received, repeats 7 times. You can select yes or no in the Alert tone level setting.
■ Individual call tone Sounds when an individual call with the correct DTMF option signalling is received. You can select yes or no in the Alert tone level setting.
■ Key input error tone Sounds when a key is pressed but that key cannot be used. You can select yes or no for the optional feature's warning tone.
■ Transpond tone Sounds when an individual call with the correct DTMF option signalling is received. For group calls, only the group tone will sound, not the transpond tone.
■ Pre alert tone Sounds prior to the TOT TX inhibit activation. If TOT pre alert is set, the tone sounds at the amount of time programmed, before the TOT expires (TOT time – TOT pre alert time = Pre alert tone sounding time). You can select yes or no for the optional feature’s warning tone.
■ Transmit protection The final FET is protected against heat while transmitting by making the radio cuts down TX power when the temperature of the final FET becomes higher than reference. After that, if the temperature continue to rise, transmission is stopped. The final FET is also protected against over voltage by having the radio to check that the voltage of power supply connected to the radio is not higher than about 17V when the radio is turned on, otherwise it can not transmit. In both cases when transmission is stopped, a beep will continue to sound until the PTT key is released.

TK-7108H CIRCUIT DESCRIPTION ■ IF Amplifier
Frequency Configuration
The first IF signal is amplified by Q351, and the enters IC301 (FM processing IC). The signal is heterodyned again with a second local oscillator signal within IC301 to create a 450kHz second IF signal. The second IF signal is then fed through a 450kHz ceramic filter (Wide : CF301, Narrow : CF302) to further eliminate unwanted signals before it is amplified and FM detected in IC301.
The receiver utilizes double conversion. The first IF is 49.95MHz and the second IF is 450kHz. The first local oscillator signal is supplied from the PLL circuit. The PLL circuit in the transmitter generates the necessary frequencies. Figure 1 shows the frequencies. ANT

Receiver System The receiver is double conversion superheterodyne. The frequency configuration is shown in Figure 1.
■ Front-end RF Amplifier An incoming signal from the antenna is applied to an RF amplifier (Q353) after passing through a transmit/receive switch circuit (D603 and D605 are off) and a band pass filter (L357, L356 and varactor diodes : D353, D354). After the signal is amplified (Q353), the signal is filtered through a band pass filter (L354, L355 and varactor diodes: D351, D352) to eliminate unwanted signals before it is passed to the first mixer. The voltage of these diodes are controlled by tracking the CPU (IC101) center frequency of the band pass filter. (See Fig. 2)

TK-7108H CIRCUIT DESCRIPTION ■ Wide/Narrow Changeover Circuit
■ Squelch Circuit
The Wide port (pin 65) and Narrow port (pin 64) of the CPU is used to switch between ceramic filters. When the Wide port is high, the ceramic filter SW diodes (D303, D302) cause CF301 to turn on to receive a Wide signal. When the Narrow port is high, the ceramic filter SW diodes (D303, D302) cause CF302 to turn on to receive a Narrow signal.
The detection output from the FM IF IC (IC301) passes through a noise amplifier (Q301) to detect noise. A voltage is applied to the CPU (IC101). The CPU controls squelch according to the voltage (SQIN) level. The signal from the RSSI pin of IC301 is monitored. The electric field strength of the receive signal can be known before the SQIN voltage is input to the CPU, and the scan stop speed is improved.

■ AF Signal System The detection signal from IF IC (IC301) goes to D/A converter (IC161) to adjust the gain and is output to AF filter (IC251) for characterizing the signal. The AF signal output from IC251 and the DTMF signal, BEEP signal are summed and the resulting signal goes to the D/A converter (IC161). The AFO output level is adjusted by the D/A converter. The signal output from the D/A converter is input to the audio power amplifier (IC252). The AF signal from IC252 switches between the internal speaker and speaker jack (J1) output. IC301

AF signal system
The frequency step of the PLL circuit is 5 or 6.25kHz. A 16.8MHz reference oscillator signal is divided at IC401 by a fixed counter to produce the 5 or 6.25kHz reference frequency. The voltage controlled oscillator (VCO) output signal is buffer amplified by Q410, then divided in IC401 by a dualmodule programmable counter. The divided signal is compared in phase with the 5 or 6.25kHz reference signal in the phase comparator in IC401. The output signal from the phase comparator is filtered through a low-pass filter and passed to the VCO to control the oscillator frequency. (See Fig. 6)
■ VCO The operating frequency is generated by Q406 in transmit mode and Q405 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes (D405 and D406 in transmit mode and D403 and D404 in receive mode). The TX/RX pin is set low in receive mode causing Q408 and Q407 to turn Q406 off, and turn Q405 on. The TX/RX pin is set high in transmit mode. The outputs from Q405 and Q406 are amplified by Q410 and sent to the RF amplifiers.

TK-7108H CIRCUIT DESCRIPTION ■ Unlock Circuit
Transmitter System
During reception, the 8RC signal goes high, the 8TC signal goes low, and Q34 turns on. Q33 turns on and a voltage is applied to the collector (8R). During transmission, the 8RC signal goes low, the 8TC signal goes high and Q36 turns on. Q35 turns on and a voltage is applied to 8T. The CPU in the control unit monitors the PLL (IC401) LD signal directly. When the PLL is unlocked during transmission, the PLL LD signal goes low. The CPU detects this signal and makes the 8TC signal low. When the 8TC signal goes low, no voltage is applied to 8T, and no signal is transmitted.
■ Outline The transmitter circuit produces and amplifies the desired frequency directly. It FM-modulates the carrier signal by means of a varicap diode.
■ Power Amplifier Circuit The transmit output signal from the VCO passes through the transmission/reception selection diode (D409) and amplified by Q501, Q502 and Q503. The amplified signal goes to the final amplifier (Q504) through a low-pass filter. The lowpass filter removes unwanted high-frequency harmonic components, and the resulting signal is goes the antenna terminal.

■ APC Circuit The automatic transmission power control (APC) circuit detects part of a final amplifier output with a diode (D606, D607) and applies a voltage to IC501. IC501 compares the APC control voltage (PC) generated by the D/A converter (IC161) and DC amplifier (IC203) with the detection output voltage. IC501 generates the voltage to control Q503 and Q504 and stabilizes transmission output. The APC circuit is configured to protect over current of Q503 and Q504 due to fluctuations of the load at the antenna end and to stabilize transmission output at voltage and temperature variations.

TK-7108H CIRCUIT DESCRIPTION ■ Key Matrix Circuit
Control Circuit 1) 2) 3) 4) 5)
The CPU carries out the following tasks: Controls the WIDE, NARROW, TX/RX outputs. Adjusts the AF signal level of the AF filter (IC251) and turns the filter select compounder on or off. Controls the display unit. Controls the PLL (IC401). Controls the D/A converter (IC161) and adjusts the volume, modulation and transmission power. CK DT LD
The TK-7108H front panel has function keys. Each of them is connected to a cross point of a matrix of the KMI1 to KMO2 ports of the microprocessor. The KMO1 to KMO2 ports are always high, while the KMI1 to KMI4 ports are always low. The microprocessor monitors the status of the KMI1 to KMO2 ports. If the state of one of the ports changes, the microprocessor assumes that the key at the matrix point corresponding to that port has been pressed.

The QT and DQT signals are output from QT/DQT of the CPU (IC101) and summed with the external pin DI line by the summing amplifier (IC203) and the resulting signal goes to the D/A converter (IC161). The DTMF signal is output from DTMF of the CPU and goes to the D/A converter (IC161). The signal is summed with a MIC signal by the summing amplifier (IC203), and the resulting signal goes to the D/A converter (IC161). The D/A converter (IC161) adjusts the MO level and the balance between the MO and QT/DQT levels. Part of a QT/ DQT signal is summed with MO and the resulting signal goes to the VCOMOD pin of the VCO. This signal is applied to a varicap diode in the VCO for direct FM modulation.

Adjustment values are sent from the CPU as serial data. The D/A converter has a resolution of 256 and the following relationship is valid: D/A output = (Vin – VDAref) / 256 x n + VDAref Vin: Analog input VDAref: D/A reference voltage n: Serial data value from the microprocessor (CPU)

Power supply circuit
Power Supply Circuit When the power switch on the display unit is pressed, the power port on the display unit which is connected port 17 (POWER), goes low, then port 82 (SBC) goes high, Q32 turns on, SB SW (Q31) turns on and power (SB) is supplied to the radio. When the DC power supplied to the radio, the voltage regulator IC (IC33) supply into the CPU VDD and reset voltage detect IC (IC34). IC34 will generate signal (RESET) in to the reset terminal on the CPU (IC101) to carry out a power ON reset. Also, CPU (IC101) is checking on port 91 (Battery Voltage). If DC power is less than about 9.5V, the radio is unable to power on. When the DC power voltage deceases from normal voltage, the INT voltage detector IC (IC35) will set to high on CPU port 18 (INT) if B line will became less than about 9.5V. Then CPU send to EEPROM (IC66) the backup data and go into STOP mode. This circuit has an overvoltage protection circuit. If a DC voltage of 18V or higher is applied to the base of Q61, this voltage turns Q61 on and turns Q32 and SB off.

If normal power is not obtained, please follow the step below Open the shielding cover (upper), and screw 3 locations around ANT pin. 1. Switch off the transceiver. Impedance of Final FET (Q504) and Drive FET (Q503) can be measured easily using DVM Ω mode. Normal condition – Gate : 20kΩ~50kΩ, Drain : 1MΩ~2MΩ The above impedance values are rough estimations. 2. Switch on the transceiver. Check the voltage at F501 output point. The voltage is around 13.6V in receiving condition. The voltage will be 12.6V~ in transmitting condition. If found 0V at this point then F501 is broken. 3. Remove R516.
4. Connect 50Ω load at the ANT location. Transmit and check current drain at High power mode. If the current drain is less than 1A, then Final FET is broken. If the current drain is less than 5.0A, short the Drive FET gate to ground, and check the current drain. If the current drain is not 0.1A less than the original value, then the Drive FET is broken. 5. Check input power level at Drive FET gate location. Connect the wire to [RF] location. Transmit and check for power to be within the range of 0.3W~0.6W. If power found is less than 0.3W, check the circuit before the Drive FET.
