2. PRE-INSTALLATION CHECKOUT
2-1. 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.
2-2. 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. Signalling equipment operation should be
verified.
3. PLANNING THE INSTALLATION
3-1. 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.
3-2. 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.
NX-820H(G)/820H
GENERAL
3-3. Radio
4-2. Radio location
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.
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.
3-4. DC Power and wiring
SERVICE
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.
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.
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 15-pin connector, fit the supplied speaker-jack cap
and ACC cap to stop dust and sand from getting in.

CIRCUIT DESCRIPTION
1. Overview
3. Receiver System
The NX-820 is a UHF Mobile transceiver designed to
operate in the frequency range of 450 to 520MHz(K-type)
or 400 to 470MHz(K2-type). The unit consists of a receiver,
transmitter, phase-locked loop (PLL) frequency synthesizer,
base band parts, power supply, and control circuits.
3-1. RF circuit
An incoming RF signal from the antenna terminal is
passed through the antenna switch (D110, 111 and 107) and
then the bandpass filter (L215, 216 and 210). The bandpass
filter is adjusted by a variable capacitor. The input voltage to
the variable capacitor is regulated by the voltage output from
the D/A converter (IC712). The signal is amplified by an RF
amplifier (Q202), and passed through the bandpass filter
(L207, 208, 209 and 211). The resulting signal is applied to
the first mixer (Q201) where it is mixed with the first local
oscillator signal output from the frequency synthesizer to
produce the first IF (49.95MHz).
2. Frequency Configuration
The receiver is a double-conversion super-heterodyne
using a first intermediate frequency (IF) of 49.95MHz and a
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 49.95MHz. This is then mixed with the 50.4MHz
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 first IF signal is passed through a four-pole monolithic crystal filter (XF1) to reject the adjacent channel signal.
The filtered first IF signal is amplified by the first IF amplifier
(Q305) and then applied to the IF system IC (IC303). 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
50.4MHz of the second local oscillator output and produces
the second IF signal of 450kHz.
The second IF signal is passed through the ceramic filter
(CF1) to reject the adjacent channel signal. The filtered second IF signal is amplified by the AGC amplifier.
The signal from the AGC amplifier is input to an AD converter in ASIC (IC507) through the ceramic filter (CF2).

CIRCUIT DESCRIPTION
3-3. Audio amplifier circuit
4-2. Base Band Circuit
Audio processing (high-pass filter, low-pass filter, deemphasized and so on) in FM mode and decoding in NXDN
mode are processed by the DSP (IC502). Audio signals from
the ASIC (IC507), IC502 goes through the amplifier (IC711).
The signal then goes through the D/A converter (IC712) and
an amplifier (IC714).
The audio signal output from the Audio band circuit is
converted to digital data with 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 so that 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 ASIC (IC507). In Digital
mode, the audio signal is converted to the 4-Level FSK base
band signal and is output from IC507. The DTMF and MSK
base band signals are also generated by the DSP and output from IC507.
LPF (IC701) works as smoothing filter. The output level
according to the transmit carrier is fine-adjusted according to
each modulation method.
3-4. Squelch Circuit
This circuit amplifies the demodulated noise signal from
the ASIC (IC507) after filtering through a LPF and HPF circuit. The amplified signal is then converted to a DC signal
by the detection circuit. The converted signal is fed back to
IC507.

4-3. Drive and Final amplifier
The signal from the T/R switch (D17 is on) is amplified
by the drive amplifier (Q102 ) to 16~17dBm. The output of
the drive amplifier is amplified by the final amplifier module
(IC102) to 45W (5.0W when the power is low). The output
of the final amplifier module is then passed through the harmonic filter (LPF) and antenna switch (D110, D111 are on)
and directional coupler and is applied to the antenna terminal.

The signal from the microphone is amplified by IC703 (1/2)
and limited by the AGC circuit composed of D703, D704,

filter.
The Automatic transmission power control (APC) circuit
stabilizes the transmitter output power at a predetermined
level by detecting the power module output with the directional COUPLER and diode detector (D104 and D105). The
diode detector (D104 and D105) applies the detected voltage to the DC amplifier IC103 (2/2).
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.

CIRCUIT DESCRIPTION
5-3. PLL IC (IC2)
5. PLL Frequency Synthesizer
5-1. TCXO (X1)
The TCXO (X1) generates a reference frequency of
16.8MHz for the PLL frequency synthesizer. This reference
frequency is applied to pin 9 of the PLL IC (IC2) and is connected to the IF circuit as a 2nd local signal through the Tripler.
The frequency adjustment is achieved by switching the
ratio of the dividing frequency. The resolution of the adjusting
frequency is approximately 4Hz.
5-2. VCO
There is an RX VCO and a TX VCO.
The TX VCO (Q6) generates a transmit carrier and the
RX VCO (Q5) generates the 1st local signal. For the VCO
oscillation frequency, the transmit carrier is 450 to 520 MHz
(K-type) or 400 to 470MHz (K2-type) and the 1st local signal
is 400.05 to 470.05MHz (K-type) or 350.05 to 420.05MHz
(K2-type).
The VCO oscillation frequency is determined by one system of operation switching terminal "T/R" and two systems of
voltage control terminals "CV" and "ASSIST".
The operation switching terminal, "T/R", is controlled by
the control line (/T_R) output from the ASIC (IC507). When
the /T_R logic is low, the VCO outputs the transmit carrier
and when it is high, it outputs the 1st local receive signal.
The voltage control terminals, "CV" and "ASSIST", are
controlled by the PLL IC (IC2) and ASIC (IC507) 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 (D16, D17)
The connection destination of the signal output from the
buffer amplifier (Q11) is changed with the diode switch (D17)
that is controlled by the transmission power supply, HSW,
and the diode switch (D16) that is controlled by the reception
power supply, 50R. If the HSW logic is high, it is connected
to a transmit-side drive (Q102). If the HSW logic is low, it is
connected to a receive-side mixer (Q202).

X1 16.8MHz
The PLL IC compares the differences in phases of the
VCO oscillation frequency and the TCXO 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 ASIC (IC507) 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 approximately 2.5V.
The desired frequency is set for the PLL IC by the ASIC
(IC507) through the 3-line "SDO1", "P_SCK1", "/PCS_RF"
serial bus. Whether the PLL IC is locked or not is monitored
by the ASIC through the “PLD” signal line. If the VCO is not
the desired frequency (unlocked), the "PLD" logic is low.

CIRCUIT DESCRIPTION
6. Control Circuit
The control circuit consists of the ASIC (IC507) and its peripheral circuits. IC507 mainly performs the following:
1) Switching between transmission and reception via the
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 the squelch on/off using the DC voltage from
the squelch circuit.
5) Controlling the audio mute circuit using the decode data
input.
6-1. ASIC
The ASIC (IC507) is a 32bit RISC processor, equipped
with a peripheral function and ADC/DAC.
This ASIC operates at 18.432MHz clock and 3.3V /1.5V
DC. It 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.
6-5. 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 IC507), the I/O section operates at 3.3V and the core section operates at 1.5V.
The DSP carries out the following processes:
• 4 level FSK processing
• Analog FM pre-emphasis/de-emphasis
• Vocoder processing between the audio codec and modulation/demodulation
• CAI processing, such as error correction encoding
• QT/DQT encoding/decoding
• DTMF encoding/decoding
• MSK encoding/decoding
• 2-tone encoding/decoding
• Compressor/expander processing
• Voice scrambler processing
• Transmit/receive audio filtering processing
• Microphone amplifier AGC processing
• Audio mute processing
• Modulation level processing
6-2. Memory Circuit
The memory circuit consists of the ASIC (IC507), the
SRAM (IC503) and the flash memory (IC501). The flash
memory has a capacity of 32Mbit which contains the transceiver control program for the ASIC and stores the data. It
also stores the data for the transceiver channels and operating parameters that are written by the FPU. This program
can be easily written from external devices. The SRAM has
a capacity of 1Mbit which contains the work area and data
area.
■ Flash memory
Note : The flash memory stores the data that is written by
the FPU (KPG-141D), tuning data (Deviation, Squelch,
etc.) and firmware program (User mode, Test mode, Tuning mode, etc.). This data must be rewritten when replacing the flash memory.
■ SRAM (static memory)
Note : The SRAM has a temporary data area and work area.
6-3. Display Unit
The display unit is composed of the LCD driver IC (IC1),
the LCD & Key backlight, etc.
The LCD is controlled using the 4 serial lines
(LCDDI,LCDCE,LCDCL,LCDDO) from the ASIC (IC507).
6-4. Key Detection Circuit
The keys are detected using an LCD driver IC (IC1). If a
pressed key is detected by IC1, the information is passed to
IC507 through the serial line.

7. Power Supply Circuit
+B is connected to the Final amplifier and the DC/DC
converter IC (IC405). IC405 regulates the +B voltage to 5.0V
(50M). 50M operates whenever +B is supplied. IC401 (33M)
and IC408 (15M) are enabled while the 50M is operating.
33M and 15M provide the power to the ASIC (IC507),
DSP (IC502), and Flash memory. At this time the ASIC
starts working. The voltage detector IC (IC402) watches the
+B voltage. If the +B voltage is higher than 8.6V, IC402 (/
BINT) outputs High. If the /BINT signal is high, Q403 (SB
SW) is turned on by the SBC signal from the ASIC. (High :
SBC=ON, Low : SBC=OFF). When the SB is turned on, IC1
(80C), IC404 (50C), Q402 (80ANT), Q404 (80T), Q415, 416
(150C), Q417 (50R) and Q408 (50CS) start working. IC409,
Q409 and Q410 are controlled by the SBC signal. If the
SBC signal becomes High, IC409 (33C) operates, and Q409
(33A_2) and Q410 (50MC SW) turn on.
The ASIC sets the TXC signal to High during transmission to the supply power (80T) for the transmission circuit.
The ASIC sets the signals (RXC) to High during reception to
the supply power (50R) for the reception circuit.
When the ASIC detects the PSW (Power switch) signal,
IGN (Ignition sense) signal or /BINT signal, it sets the SBC
signal to Low, and turns the transceiver power (SB) off.
When D401 and Q401 detect an over-voltage condition, they
turn Q403 (SB SW) off, but the ASIC continues to function.

CIRCUIT DESCRIPTION
8. Signaling Circuit
8-1. Encode (QT/DQT/DTMF/2TONE/MSK)
Each signaling data signal of the QT, DQT, DTMF, 2TONE
and MSK is generated by the DSP circuit, superposed on a
modulation signal and output from the ASIC (IC507). Each
deviation of the TX QT, DQT, DTMF, 2TONE and MSK tones
are adjusted by changing the output level of the DSP (IC502)
and the resulting signal is routed to the VCO and PLL.
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
by the DSP.
9. Compander Circuit
The term “compander” means compressor and expander.
The compander reduces noise by utilizing a compressor and
an expander. The DSP (IC502) performs this operation. The
ompander can be turned on or off using the FPU.
10. GPS Circuit (GPS model only)
The GPS information function can be used by setting it
through the FPU. The GPS signal of 1575.42MHz received
with the GPS active antenna (with a built-in LNA) is processed by the GPS module (A801) and input to the ASIC
(IC507) through the UART port. The ASIC (IC507) processes
the GPS data (NMEA) and sends the resulting information to
the LCD.

Preparations for checking/tuning the transceiver
Before attempting to check/tune the transceiver, connect
the unit to a suitable power supply.
Whenever the transmitter is turned on, the unit must be
connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a
4 dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during checking/tuning.
