GENERAL

PERSONAL SAFETY

The following precautions are recommended for personal

safety :

•DONOT transmit if someone is within two feet (0.6

meter) of the antenna.

•DONOT 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 tech-

nicians.

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 permit-

ted 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. How-

ever, it is recommended that receiver and transmitter opera-

tion 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. Signaling equipment operation should be

verified.

NX-800

4. PLANNING THE INSTALLATION

4-1. General

Inspect the vehicle and determine how and where the ra-

dio 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.

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 rec-

ommended.

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.

GENERAL

SERVICE

3. Receiver System

3-1. RF circuit

The front-end circuit consists of former BPF (D212, D213),

RF amplifier Q210, and latter BPF (D207, D208, D209 and

D210).

The BPF covers frequency ranges 450 to 520MHz.

The latter BPF (D207, D208, D209 and D210) attenuates

the unwanted signals, and sends only the necessary signal to

the first mixer.

1. Overview

NX-800 is a UHF Mobile transceiver designed to operate in

the frequency range of 450 to 520MHz. The unit consists of

receiver, transmitter, phase-locked loop (PLL) frequency syn-

thesizer, base band parts, power supply, and control circuits.

2. Frequency Configuration

The receiver is a double-conversion super heterodyne

using first intermediate frequency (IF) of 58.05MHz and sec-

ond 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 amplified and fed to the antenna.

3-3. IF circuit

The first IF signal is passed through a four-pole monolithic

crystal filter (XF202) to reject adjacent channel signal. The

filtered first IF signal is amplified by the first IF amplifier

(Q204, Q205) and then applied to the lF system IC (IC202).

The IF system IC provides a second mixer, AGC amplifier,

and RSSI (Received Signal Strength Indicator).

The second mixer mixes the first IF signal with the

57.6MHz of second local oscillator output and produces the

second IF signal of 450kHz.

CIRCUIT DESCRIPTION

3-4. Audio amplifier circuit

Audio processing (high-pass filter, low-pass filter, de-

emphasized and so on) at FM mode and decoding at NXDN

mode are processed by DSP. Audio signal from IC510, IC502

goes through the amplifier (IC701). The signal then goes

through mute switch (IC707), amplifier (IC711), and elec-

tronic volume control (IC712).

While busy, INAMT becomes High, turn switch (Q709) on

and Mute switch (Q710) off, and signal is fed to AF Power

Amp (IC715). While Non-busy, INAMT is become Low, turn

switch (Q709) off and Mute switch (Q710) on, then there is

not AF output.

It amplifies the demodulated noise signal from IC202 after

filtering through BPF circuit. Then, the amplified signal is con-

verted to DC signal by the detection circuit. The converted

signal is fed back to IC510.

The second IF signal is passed through the ceramic filter

(CF201, CF202) to reject the adjacent channel signal. The

filtered second IF signal is amplified by AGC amplifier.

The signal from AGC amplifier is input to AD converter

(IC510) through ceramic filter (CF203) and operational ampli-

fier (IC201 and IC704).

4-3. Drive and Final amplifier

The transmit signal obtained from the TX VCO buffer am-

plifier Q9, is amplified to approximately +17dBm by the driver

amplifiers Q10, Q101 and Q102.

This amplified signal is passed to the power amplifier

module(power module)IC102, which consists of a MOS-FET

amplifier and capable of transmission output power.

4-4. APC circuit

The Automatic transmission power control (APC) circuit

stabilizers the transmitter output power at a predetermined

level by detecting the power module output with a diodes

D108, D109 and D110. Diodes D108, D109 and D110 apply a

voltage to DC amplifier IC103 (1/2).

IC103 (2/2) compares the APC control voltage (PC) gener-

ated by microprocessor IC510 and DC amplifier IC101 (1/2,

2/2) with the detection output voltage from IC103 (1/2) to

control the Vgg Pin of IC102, and stabilizes transmission output.

The APC circuit is configured 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.

4. Transmitter System

4-1. Audio Band Circuit

The signal from the microphone goes through the mute

switch (Q706), the Mic-Mute signal (MM) becomes Low,

then mute switch (Q706) is turned off. The signal from mi-

crophone goes through Mic-AGC (Q704, Q705, D704, D705),

and goes through switch IC (IC708), and amplified by Mic-

Amp IC706 (1/2), LPF IC706 (2/2) works as anti-aliasing filter.

If an optional scrambler board is installed, the switch

(IC708) adjusts the signal path so that the audio signal is input

to the scrambler board.

4-2. Base Band Circuit

The audio signal output from the base band circuit is con-

verted to digital data of a sampling frequency of 48 kHz. 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 filter. 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 fine-adjusted according to each modulation method.

CIRCUIT DESCRIPTION

5. PLL Frequency Synthesizer

5-1. VCTCXO (X1)

VCTCXO (X1) generates a reference frequency of

19.2MHz 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 fixed 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 fre-

quency 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 520 MHz and the 1st

local signal is 391.95 to 461.95MHz.

The VCO oscillation frequency is determined by one sys-

tem 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 CPU (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 CPU (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 CPU 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 CPU

(IC510) through the 3-line "SDO1", "SCK1", "PCS_RF" serial

bus. Whether the PLL IC is locked or not is monitored by the

CPU 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 amplifier (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 con-

nected to a send-side pre-drive (Q101). If the 80T logic is

low, it is connected to a local amplifier (Q208).

6. Control Circuit

The control circuit consists of CPU (IC510) and its periph-

eral 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. CPU

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

peripheral function and ADC/DAC.

This CPU 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 CPU (IC510) and the SRAM

(IC503), the flash memory (IC501). The flash memory has

capacity of 32Mbit that contains the transceiver control

program for the CPU 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 flash memory stores the data that is written by the

FPU (KPG-111D), tuning data (Deviation, Squelch, etc.), and

firmware 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 internal

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 CPU (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 oper-

ates 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

7. Power Supply Circuit

+B is connected to Final amplifier 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 CPU, DSP, and Flash

memory. At this time CPU 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 CPU. (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) oper-

ates and Q412 (50MC SW) are turned on.

The CPU controls the TXC signal to High during transmis-

sion to supply power (80T) for transmission circuit. The CPU

controls the signals (RXC) to High during reception to supply

power (80R, 50R) for reception circuit.

When the CPU 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 CPU 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 out-

put 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 contains DSP (IC502) to perform

this operation. The NX-800 compander can be turned on or

off using the FPU.

TROUBLE SHOOTING

NX-800

Fault diagnosis of the BGA (Ball Grid Array) IC

Overview: A flowchart 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 (X57-7390-11) in for service. Various ESN/default adjust-

ment values are written on the printed circuit board for service. Additionally various ESN stickers are included. The power module

(RA30H4452M123), 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.

Panel Tuning Mode

■ Preparations for tuning the transceiver

Before attempting to tune the transceiver, connect the

unit to a suitable power supply.

Whenever the transmitter is turned, the unit must be con-

nected to a suitable dummy load (i.e. power meter).

The speaker output connector must be terminated with a

4Ω dummy load and connected to an AC voltmeter and an

audio distortion meter or a SINAD measurement meter at all

times during tuning.

■ Transceiver tuning (To enter tuning mode)

To enter tuning mode, press the [ ] key while the trans-

ceiver is in test mode. Use the [ ] key to write tuning data

through tuning modes, and the [ ]/[ ] key to adjust tuning

requirements (1 to 4096 appears on the LCD).

Use the [ ] key to select the adjustment item through

tuning modes. Use the [ ] key to adjust 5 reference level

adjustments, and use the [■] key to switch between Wide/

Narrow/Very narrow.
