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. L1CI;NSING 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.
OT equipment operation should be verified.

GENERAL
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. 8e 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.
CAUTION
If DC power is to be controlled by the vehicle ignition switch, a switching relay should be used to switch the positive power lead. The vehicle ignition switch then controls DC to the relay coil.
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.
Note
When you modify your radio as described in system set-up, take the following precaution.
The rating of pin 7 (58) of the accessory connector cable (KCT-19) on the rear of the radio is l3.6V (lA).
Insert a 1A fuse if you use the 58 pin for external equipment.
If you do not intend to use the 3.5-mm jack for the external speaker, fit the supplied speaker-jack cap
(809-0235-XX) to stop dust and sand getting in.

3-2. Final amplifier
The signal from the PLL is amplified by drive amplifier (0205, 206) and power module (IC501) to an output level of 25W/45W, and goes through the antenna switch D20 and harmonic filter, and on to the antenna terminal.
IC13 (1/2) compares the DC input to pin 2 with the reference voltage at pin 3 applied by IC8 (1/2), amplifies the result, and controls the DC amplifier (022 and
023) to keep the transmit final current constant, thus keeping the transmit output constant.
3-3. APC circuit
The direct current that flows through the power module (IC501) produces a voltage across resistors
R108. This voltage is applied to pin 6 of IC13 (2/2), and is input as the reference voltage difference of pin 5 and amplified.

4. Frequency Synthesizer Unit
4-1. VCO/PLL
The PLL generates the transmit signal and the first local oscillator receive signal. The RF signal generated by 05 (TX) or 02 (RX) in the VCO unit is amplified by
03, and the resulting signal is output to the TX-RX unit.
TX and RX 05 and 02 are switched by turning the source line for 05 and 02 on and off. This is done by
04 and 01 using the control signal (STR) generated by the serial-to-parallel converter in the TX-RX unit. The
RF signal passes through 03 of the VCO unit and amplifier 0209 of the TX-RX unit, and is input to IC202
(PLL IC). The 12.8MHz PLL reference signal generated by the VCXO (X1) in the TX-RX unit is also input to
IC202.
Both signals are divided according to the division data from the control unit to produce a 12.5kHz signal.
The phases are compared, and a phase difference signal is output and passes through the charge pump (in
IC202) and the low-pass filter of the lug lead to produce the control voltage for 05/02 (VCOl. This voltage is applied to D3 and D4 (TX) or D1 and D2 (RX) in the VCO unit to keep the VCO frequency constant. The other output from 03 is amplified by the RF amplifier (018), and output to the transmit or receive unit via the RF switch (D17).

CIRCUIT DESCRIPTION
6-1.
Memory circuit
IC201 is a 8-Kbit EEPROM that stores adjustment and backup data.
• Shift register
IC10 is an interface IC for I/O port expansion. It is used to expand the CPU (lC409) output ports.
• 0/A converter
IC6 is used as a conventional semi-fixed-resistor converter. It sets the following:
1) RX sensitivity
2) Transmission power
3) Modulation level
4) Audio power
5) Frequency
6-2. TX encode data
The CPU (IC409) transmits encode data.
aT, DOT, OTMF
OT, DOT data items are output from CPU pin 16.
The signal from this pin passes through the CR lowpass filter and goes to the summing amplifier (IC404) in the microphone amplifier. DTMF data is output from
CPU pin 10. This signal passes through the CR lowpass filter and goes to IC402 in the IDC circuit of the microphone amplifier. These are mixed with the audio signal and output to the splatter filter. It then goes to the D/A converter (lC6) and on to the VCXO and VCO.

Th receive detection signal pass through a low-pass filter IC401 (1/2). This signal is input to pin 11 of the
CPU.
• OTMF
DTMF decoding is made available by installing the
DTMF decode IC (LC73881 M : SANYO) on the control board.
6-4.
Pll data output
PLL data is output from DATA (pin 60), ENABLE (pin
73), and CLOCK (pin 58) of the CPU (lC209). The signals are input to the PLL IC (IC202) when the channel is changed or when transmission is changed to reception and vice versa.
6-5. Horn control
The horn switch, consisting of 013,014, and 024, controls the horn relay. It is supplied by the dealer to provide the external horn alert function.
024 disables horn alert, turning on when its base is high, to inhibit the function. Normally, the output from
IC10 is low, and 013 is off; the base of 014 is about OV and 014 is off. When horn alert is enabled, the output from IC10 goes high and 013 turns on. The base current flows through R61 to 014 to turn 014 on. 014 can sink a maximum of 100mA. If the optional KAP-l is used, it can drive up to 2A.

6-6. PA switch
If the optional KAP-l is used (see the separate section for details), the PA (Public Address) function becomes available. In this case, the signal flow changes as follows;
• PA off
For TX, 0410 turns on and 0407 turns off. The audio signal from the microphone passes through 0410 and IC6 and modulates the VCO.
For RX, the detected signal passes through 0404 which is on.
It then passes through the audio filter,
IC403, IC405, D/A IC (IC6), and is output to the speaker through the audio power amplifier ICll.
• PA on
Since 0410 is off, 0407 is on, and 0404 is off, the audio signal from the microphone goes to the audio filter IC403, passes through IC6, and goes to ICll. The signal is output to the external PA system through the
PA relay in the KAP-l.

6-7. Power supply circuit
D4 protects IC1 against overvoltage.
Each time a pulse comes from the PSW terminal, the IC1 output is reversed. The reversed output signal passes through
01 and 03 and drives 04. A voltage must be applied to the IGN terminal.
If 24V is supplied to the transceiver by mistake, 02 turns on, and 03 and 04 are forced off, so the transceiver does not turn on.

Транковый режим выбирается при установленной плате логики Smart Trunk IIтм.
Таблица 2
Режим Пользование
Режим пользователя Обычно этот режим стартует при включении питания
Режим дилера При нажатой клавише [A] включите питание. После включения удерживать клавишу [A] нажатой до появления надписи PROG на дисплее. Если надпись не появляется то режим дилера запрещен и доступ к нему осуществляется только с PC программатора.
Режим проверки панели При включении питания держите нажатой клавишу [D/A]. Эта клавиша удерживается нажатой примерно 2 секунды. Если этот режим запрещен, то начнется режим пользователя. Доступ можно разрешить с РС программатора.
Режим настройки с панели При включении питания держите нажатой клавишу [SCN]. Эта клавиша удерживается нажатой примерно 2 секунды. Если этот режим запрещен, то начнется режим пользователя. Доступ можно разрешить с РС программатора.
Режим программирования с РС Включите радиостанцию в режиме пользователя когда в разъём микрофона включен программатор KPG – 4, который с другой стороны присоединён к порту RS – 232C компьютера РС. Для программирования и настройки параметров программа KPG – 29D.
Программирование с передней панели (самопрограммирование).

Я на прошлой работе использовал TK760G, несколько штук. И программировал их успешно самодельным универсальным программатором.
Сохранился каталог, в котором собирал необходимое для работ с этой радиостанцией: фотки плат, распиновка, схемы подключения, статьи как программировать без программатора кнопками, принципиальная схема самой радиостанции, штатная прошивка из проги, программы (kpg56d версий 2.0, 2.10, 4.0, kpg67d). Какая из этих прог у меня пошла — уже не помню, кажись kpg56d v4.0, так как файлы настроек ею слитые сохранились.
Для связи с программатором использовал настоящий железный COM порт старенького компа, не переходник с USB. Если прога и была DOSовской, то вряд ли я делал загрузочный диск MS-DOS, кажись запускал проги для прошивки из-под WinXP.
Для справки:
Если запускаете DOS программу из-под винды, то винда предоставит этой эмуляции DOS и запускаемой программе свои ресурсы, включая COM порты. Чем я и пользовался, прошивая некоторые радиостанции DOS программами из-под винды.
Но не все DOS программы будут использовать ресурсы винды так, как она это им это предлагает делать. Некоторые DOS программы устроены так, что обращаются напрямую к COM порту, через оборудование, предоставляемое БИОСом, а не через предоставляемый операционной системой драйвер. В таком случае DOS прога не станет работать из-под винды с USB-COM или большинством PCI-COM, PCMCIA-COM картами.
Даже если установить в комп плату PCI-COM, не факт что она будет работать в чистом DOS, без винды. Так как и БИОС не знает как с ней общаться, и дров для DOS для этой платы Вы вряд ли найдёте. Это наиболее вероятный исход событий. Исключение будут составлять платы кажется на чипах от Moschip, и ещё пары не часто встречающихся фирм. Эти чипы распознаются БИОСом как нормальный «железный» COM порт, и его без всяких дров можно использовать в чистом DOSе. Та же ситуация с PCMCIA-COM картами для ноутов. А переходники USB-COM в чистом DOSе не будут работать совсем, т.к. дров для DOS под них нету, и БИОС их не знает.
