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 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.

PERSONAL SAFETY

The following precautions are recommended for personal

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 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 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. Introduction

Each radio is adjusted and tested before shipment. How-

ever, 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 ﬁ nal installation. Transmitter frequency, deviation, and power output should be checked, as should receiver sensitivity, squelch operation, and audio output. Signaling equipment operation should be veriﬁ ed.

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 crush-

ing wiring, and radio installation to prevent overheating.

2

GENERAL

NX-800/800H

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 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 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 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.

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 speaker 3.5-mm jack and

the D-sub 25-pin connector, ﬁ t the supplied speaker-jack

cap and D-sub cap to stop dust and sand from getting in.

• If the transceiver is turned ON or OFF when the power-

on/off status message is enabled, the transceiver sends

the status.

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 sufﬁ cient air can ﬂ ow around the radio and power supply to allow adequate cooling.

2. Frequency Conﬁ guration

The receiver is a double-conversion super heterodyne using first intermediate frequency (IF) of 58.05MHz and second IF of 450kHz. Incoming signals from the antenna are mixed with the local signal from the PLL circuit to produce the first IF of 58.05MHz. This is then mixed with the 57.6MHz second local oscillator output to produce the 450kHz second IF. The transmit signal frequency is generated by the PLL VCO, and modulated by the signal from the DSP. It is then ampliﬁ ed and fed to the antenna.

4-2. Base Band Circuit

The audio signal output from the base band circuit is converted to digital data of a sampling frequency of 48kHz. This digital data is sent to the DSP (IC502), and voice signals of 300Hz or lower and frequencies of 3kHz or higher are cut off and an audio range 300Hz to 3kHz 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 IC510. In Digital mode, the audio signal is converted to the 4-Level FSK base band signal and output from the IC510. The DTMF and MSK base band signals are also generated by the DSP and output by the IC510.

LPF (IC702) works as smoothing ﬁ lter. The DAC (IC712) assigns the base band signal to the VCO and VCTCXO (X1). At this time, the level output according to the transmit carrier is ﬁ ne-adjusted according to each modulation method.

The APC circuit is conﬁ gured to protect over-current of the power module due to fluctuations of the load at the antenna end and to stabilize transmission output at voltage and temperature variations.

CIRCUIT DESCRIPTION

5. PLL Frequency Synthesizer

5-1. VCTCXO (X1)

VCTCXO (X1) generates a reference frequency of 19.2 MHz for the PLL frequency synthesizer. This reference frequency is applied to pin 9 of the PLL IC (IC3) and connected to IF circuit as a 2nd local signal through Tripler. The VCTCXO oscillation frequency is determined by DC voltage of VC terminal. The VC voltage is ﬁ xed to 1.65V by R1 and R2, and supplied to VC terminal through IC2. Modulation signal is also fed to VC terminal through IC2.

The frequency adjustment is achieved by switching the ratio of dividing frequency that is not adjusted by the DC voltage impressed to VC. The resolution of adjusting frequency is approximately 4Hz.

5-2. VCO

There is a RX VCO and a TX VCO.

The TX VCO (Q6) generates a transmit carrier and the RX VCO (Q5) generates a 1st local signal. For the VCO oscillation frequency, the transmit carrier is 450 to 520MHz and the 1st local signal is 391.95 to 461.95MHz.

The VCO oscillation frequency is determined by one system of operation switching terminal “T/R” and two systems of voltage control terminals “C/V” and “V-assist”.

The operation switching terminal, “T/R”, is controlled by the control line (/T_R) output from the MCU (IC510). When the /T_R logic is low, the VCO outputs the transmit carrier and when it is high, it outputs a 1st local receive signal.

The voltage control terminals, “CV” and “V-assist”, are controlled by the PLL IC (IC3) and MCU (IC510) and the output frequency changes continuously according to the applied voltage. For the modulation input terminal, “VCO MOD”, the output frequency changes according to the applied voltage. This is used to modulate the VCO output. “VCO MOD” works only when “/T_R” is low.

5-3. PLL IC (IC3)

PLL IC compares the differences in phases of the VCO oscillation frequency and the VCTCXO 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 MCU 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 approx. 3.0V.

The desired frequency is set for the PLL IC by the MCU (IC510) through the 3-line “SDO1”, “SCK1”, “PCS_RF” serial bus. Whether the PLL IC is locked or not is monitored by the MCU through the “PLD” signal line. If the VCO is not the desired frequency (unlock), the “PLD” logic is low.

5-4. Local Switch (D101, D205)

The connection destination of the signal output from the buffer ampliﬁ er (Q10) is changed with the diode switch (D101) that is controlled by the transmission power supply, 80T, and the diode switch (D205) that is controlled by the receive power supply, 50R. If the 80T logic is high, it is connected to a send-side pre-drive (Q101). If the 80T logic is low, it is connected to a local ampliﬁ er (Q208).

CIRCUIT DESCRIPTION

NX-800/800H

6. Control Circuit

The control circuit consists of MCU (IC510) and its pe-

ripheral circuits. IC510 mainly performs the following;

1) Switching between transmission and reception by PTT signal input.

2) Reading system, zone, frequency, and program data from the memory circuit.

3) Sending frequency program data to the PLL.

4) Controlling squelch on/off by the DC voltage from the squelch circuit.

5) Controlling the audio mute circuit by decode data input.

6-1. MCU

The MCU (IC510) is 32bit RISC processor, equipped with

peripheral function and ADC/DAC.

This MCU operates at 18.432MHz clock and 3.3V /1.5V

DC. Controls the flash memory, SRAM, DSP, the receive circuit, the transmitter circuit, the control circuit, and the display circuit and transfers data to or from an external device.

6-2. Memory Circuit

Memory circuit consists of the MCU (IC510) and the

SRAM (IC503), the ﬂ ash memory (IC501). The ﬂ ash memory has capacity of 32Mbit that contains the transceiver control program for the MCU and stores the data. It also stores the data for transceiver channels and operating parameter that are written by the FPU. This program can be easily written from external devices. The SRAM has capacity of 1Mbit that contains work area and data area.

Flash memory

■

Note: The ﬂ ash memory stores the data that is written

by the FPU (KPG-111D), tuning data (Deviation, Squelch, etc.), and ﬁ rmware program.

SRAM (static memory)

■

Note: The SRAM has temporary data area and work

area.

When the power supply is off, it is backed up by an inter-

nal secondary lithium battery. Therefore, the save data does not break.

Real-time clock

■

The clock function is based on real-time clock IC (IC504).

When the power supply is off, it is backed up by an internal secondary lithium battery

6-3. Display Unit

The display unit is composed of the MCU (IC911) and

the memory IC (IC913), and the LCD & Key backlight etc.

The LCD Ass’y (with LCD Driver) is controlled using the

bus lines on the connector (CN905) of the display unit. It corrects the LCD contrast voltage using IC909.

6-4. Key Detection Circuit

Keys are detected using Key scan circuit in IC911. The /KI* and KO* signals that are normally pulled up go low when any key is pressed.

6-5. DSP

The DSP circuit consists of a DSP (IC502) and processes the base band signal. The DSP operates on an external clock of 18.432MHz (the same as the IC510), the I/O section operates at 3.3V and the core section operates at 1.5V. The DSP carries out the following processes:

• 4Level FSK processing

• Analog FM pre-emphasis/de-emphasis

• Vocoder processing between audio codec and modula-

tion/demodulation

• CAI processing, such as error correction encoding

• QT/DQT encoding/decoding

• DTMF encoding/decoding

• MSK encoding/decoding

• 2TONE encoding/decoding

• Compressor/expander processing

• Voice scrambler processing

• Transmit/receive audio ﬁ ltering processing

• Microphone ampliﬁ er AGC processing

• Audio mute processing

• Modulation level processing

7. Power Supply Circuit

+B is connected to Final ampliﬁ er and DC/DC converter IC (IC405). IC405 regulates +B voltage to 5.0V (50M). 50M operates whenever +B is supplied. IC402 (33M), IC408 (33A) and IC409 (15M) are enabled while the 50M are operating.

33M and 15M provide the power to MCU, DSP, and Flash memory. At this time MCU starts working. Voltage detector IC (IC401) watches +B voltage. If +B voltage is higher than 8.6V, IC401 (/BINT) outputs High. If the /BINT signal is high, Q404 (SB SW) is turned on by SBC signal from MCU. (High: SB=ON, Low: SB=OFF). When the SB is turned on, IC403 (80C), IC404 (50C), IC406 (33C), IC407 (33GPS) and IC410 (150C) start working. Q416 and Q412 are controlled by SBC signal. If the SBC signal becomes High, Q416 (33A-2) operates and Q412 (50MC SW) are turned on.

The MCU controls the TXC signal to High during transmission to supply power (80T) for transmission circuit. The MCU controls the signals (RXC) to High during reception to supply power (80R, 50R) for reception circuit.

When the MCU detects the PSW (Power switch) signal, IGN (Ignition sense) signal or /BINT signal, it controls the SBC signal to Low, and turns the transceiver power (SB) off. When D401 and Q401 detect over-voltage condition, they turns Q404 (SB SW) off. But the MCU still works.

If +B is not provided to the transceiver, the power is provided to SRAM and RTC through the secondary battery connected with CN405.

8. Signaling Circuit

8-1. Encode (QT/DQT/DTMF/MSK/2TONE)

Each signaling data signal of QT, DQT, DTMF and MSK is generated by the DSP circuit, superposed on a modulation signal and output from IC510. The modulation balance of the QT/DQT signal is adjusted by the D/A converter (IC712) and the resulting signal is routed to the modulation input of the VCO and VCTCXO (X1). The each deviation of the TX QT, DQT, DTMF and MSK tone is adjusted by changing the output level of the IC510 and the resulting signal is routed to VCO and VCXO. The RX DTMF tone is routed to the receive audio signal system, and is output from the speaker.

8-2. Decode (QT/DQT/DTMF/2TONE/MSK)

The audio signal is removed from the FM detection signal sent to the DSP circuit and the resulting signal is decoded.

9. Compander Circuit

The term “compander” means compressor and expander. The compander reduces noise by utilizing a compressor and an expander. The NX-800/800H contains DSP (IC502) to perform this operation. The NX-800/800H compander can be turned on or off using the FPU.

TROUBLE SHOOTING

Fault diagnosis of the BGA (Ball Grid Array) IC

Overview: A ﬂ owchart for determining whether or not the transceiver can be powered on (the LCD does not function even if

the power switch is turned on) due to broken BGA parts.

BGA parts: ASIC (IC510), DSP (IC502), FLASH (IC501), SRAM (IC503)

When the BGA IC is problematic, please bring the printed circuit board (X57-7390-XX) in for service. Various ESN/default adjustment values are written on the printed circuit board for service. Additionally various ESN stickers are included. The power module (RA30H4452M123: K, RA55H4452M123: HK), short connector (E37-1180-05) and button type lithium battery (W09-0971-05) do not belong to the printed circuit board for service. Please use the part which has been attached to the printed circuit board. After the printed circuit board has been readjusted, please attach any ESN stickers to the chassis. When “ESN Validation” is used with NXDN Trunking, you must modify the ESN register.

When an abnormal value is confirmed.

Checking for an abnormal point

33M has an abnormal voltage. [ASIC] Remove L508 to check the voltage of the 33M. If the voltage becomes normal, the ASIC is broken. [DSP] Remove L503 to check the voltage of the 33M. If the voltage becomes normal, the DSP is broken. [FLASH] Remove L501 to check the voltage of the 33M. If the voltage becomes normal, the FLASH is broken.

15M has an abnormal voltage. [ASIC] Remove L511 to check the voltage of the 15M. If the voltage becomes normal, the ASIC is broken. [DSP] Remove L502 to check the voltage of the 15M. If the voltage becomes normal, the DSP is broken.

33A has an abnormal voltage. [ASIC] Remove R603 to check the voltage of the 33A. If the voltage becomes normal, the ASIC is broken.

33BU has an abnormal voltage. [SRAM] Remove L522 to check the voltage of the 33BU. If the voltage becomes normal, the SRAM is broken.

If the voltage is not corrected, there is a problem other than the BGA parts.

Remove the R569, R511 and R545. If it oscillates normally, the DSP and ASIC may be broken.

The BGA parts are not broken.

● Checking the output signal from the ASIC
