GENERAL  
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.  
SERVICE  
This radio is designed for easy servicing. Refer to the  
schematic diagrams, printed circuit board views, and align-  
ment procedures contained in this manual.  
NOTE  
4-2. Antenna  
• If you do not intend to use the speaker 3.5-mm jack and  
the D-sub 25-pin connector, fit 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.  
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.  
Ignition

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.

PC or compatible) using the interface cable (KPG-46/46A) and  
USB adapter (KCT-53U : when the interface cable is KPG-  
46A, the KCT-53U can be used.). (Connection is the same as  
in the PC Mode.)  
Programming data can be transferred from one radio to  
another by connecting them via their 8-pin microphone con-  
nectors. The operation is as follows (the transmit radio is the  
master and the receive radio is a slave).  
The following data cannot be cloned.  
• Tuning data  
• Embedded message with password  
• ESN (Electronic Serial Number) data

CIRCUIT DESCRIPTION  
1. Overview  
2. Frequency Configuration  
NX-800 is a UHF Mobile transceiver designed to operate in  
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.  
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.

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.  
The signal from the BPF is heterodyned with the first local  
oscillator signal from the PLL frequency synthesizer circuit at  
the first mixer DBM (IC204) to become a 58.05MHz first  
intermediate frequency(IF) signal.  
The first IF signal is fed through a monolithic crystal  
filter(XF202) to further remove spurious signals.

CIRCUIT DESCRIPTION  
3-3. IF circuit  
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).  
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.

through mute switch (IC707), amplifier (IC711), and elec-  
tronic volume control (IC712).  
It amplifies the demodulated noise signal from IC202 after  
filtering through BPF circuit. Then, the amplified signal is con-

CIRCUIT DESCRIPTION  
4-2. Base Band Circuit  
4. Transmitter System  
4-1. Audio 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.  
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.  
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.

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.  
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.  
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.

CIRCUIT DESCRIPTION  
5-3. PLL IC (IC3)  
5. PLL Frequency Synthesizer  
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.  
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.  
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.  
5-2. 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.  
5-4. 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).

CIRCUIT DESCRIPTION  
6-4. Key Detection Circuit  
6. Control 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.  
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.  
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  
5) Controlling the audio mute circuit by decode data input.  
• 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  
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.  
• Compressor/expander processing  
• Voice scrambler processing  
• Transmit/receive audio filtering processing  
• Microphone amplifier AGC processing  
• Audio mute processing  
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.  
• Modulation level processing  
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.  
■ 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  
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.  
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.

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

TROUBLE SHOOTING  
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.

ADJUSTMENT  
■ Frequency and Signaling  
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.  
The transceiver has been adjusted for the frequencies  
shown in the following table. When required, readjust them  
following the adjustment procedure to obtain the frequencies  
you want in actual operation.
