• 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.

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.

electronic 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

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.

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.
