Circuit Description
5.1 Frequency configuration
The reference frequency of frequency synthesizer is provided by 16.8MHz crystal oscillator X1 TCXO.
The receiver adopts quadric mixing mode. The first IF is 49.95MHz, and the second IF is 450kHz. The
first local oscillation signal of the receiver is produced by frequency synthesizer and the second local
oscillation signal selects the 4rd harmonics of 16.8MHz of crystal oscillator X1 TCXO. The signal of
transmitter is produced by frequency synthesizer directly.
Figure 1 Frequency configuration
5.2 Receiver（Rx）
The receiver is double conversion superheterodyne,designed to operate in the frequency range of
400 to 470MHz,The frequency configuration in Fig 1.1
Figure 2 Receiver section configuration
Front End of Receiver
Signals from the antenna are filtered by BPF which consists of C235 C236 C233 C604 C252 C951 C234
22
DR6000-2/DR7000-2 Service Manual
C255 C260 L211 L209 L208 D201 D202 and D204 via RX/TX switch (D101 D102 and D103). After
being filtered out the useless out-of-band signals, the signals are amplified by LNA consisting of Q203
and external components.
Signals from LNA are filtered again by BPF which consists of C228 C226 C238 C229 C227 C239 C947
C259 C948 L214 L204 L203 D905 D203 and D206 before entering the 1st mixer (Q202).
The PWM wave is output by MCU composed of 58 foot and then commutated to adjustable voltage after
filtering to change the capacity of varactor diode D905 D203 D206 D201 D202 and D204 to control the
center frequency of BPF.
1st mixer
The first IF (49.95MHz) signal is produced after mixing of the receiving signal from LNA and the 1st local
oscillation signal from frequency synthesizer. The first IF signal is filtered out adjacent channel and other
useless signals by crystal filter (XF201).
IF Circuit
The 1st IF signal from crystal filter is amplified by the first IF amplifier (Q201) before processing of IC in
IF( IC200，NJM2591V or TA31136FN).
IF IC consists of the 2nd mixer, 2nd local oscillation, IF amplifier, limiter, frequency discriminator and noise
amplifier.
Frequency (16.8MHz) produced by TCXO(X1) is amplified and then selects 3rd harmonics (51.4MHZ) as
the second local oscillator signal source. The second IF signals (450kHz) are generated after signals
mixing of the second local oscillation (51.4MHz) and the first IF (49.95MHz) in IC200. Audio signals are
demodulated and outputted by IC200 after the second IF signals are amplified and limited in IC200 and
then filtered by ceramic filter(450kHz).

Figure 3 Schematic Diagram for IF System
Receiving Audio Signal Processing:
The audio processing circuit of receiver consists of IC300. Voice signals from IC300 are sent to IC301
（CTCSS signaling filter circuit.
Squelch Circuit
Part of the AF signal from the IC200 enters the FM IC again,and the noise component is amplified
and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level.
The DC signal from the FM IC goes to the analog port of the microprocessor(IC403).IC403
determines whether to output sounds from the speaker by checking whether the input voltage is higher
or lower than the preset value.
To output sounds from the speaker,IC403 sends a high signal to the MUTE and AFCO lines and turns
IC302 on through Q302 Q304 and Q305.
Audio Power Amplification
The audio power amplifying circuit consists of IC302 and the peripheral components.
The signals are amplified by audio power amplifier to drive the speaker after collecting the receiving
audio signals, voice signals and warning tone signals. The warning tone has no volume limitation.
When AFCO is high level, Q304 is on, IC302 begins to work and the speaker sounds. Speaker
Impedance: 16ohm
CTCSS Signal filtering
24
DR6000-2/DR7000-2 Service Manual
The audio signals after demodulation in IC200 may contain CTCSS (continuous tone control squelch
system) or DCS（digital squelch）signals. The spectrum component of CTCSS/DCS is 67 to 250Hz. The
filtering circuit composed of IC301 can filter out signals except CTCSS/DCS spectrum, which makes
MCU decode the CTCSS/DCS more accurately.
5.3 Transmitter (Tx)
Transmitter Power Amplifier
Figure 4 Schematic Diagram for Power Amplifier and Antenna Switch
The modulated RF signals from VCO are amplified by Q101, Q102 and Q105 before the power
amplification in Q107.
Gate bias of Q105 and Q107 is controlled by APC circuit, so the output power of transmitter can be
controlled conveniently by changing the gate bias voltage.
APC（Automatic Power Control）
Figure 5 Schematic Diagram for APC Circuit
R130 R131 and R132 are power amplification current detector, IC100A is power amplification current
sampling amplifier and IC00B is power comparison amplifier.
The power amplification current and IC100A output will increase with oversized output power of
transmitter. When the output voltage of IC100B decreases, the bias voltage of Q105 and Q107 will
25
DR6000-2/DR7000-2 Service Manual
decrease, finally the output power of transmitter will decrease or vice versa. Thus, the output power of
transmitter will keep stable under any different working condition.
MCU can set the power by changing the voltage input to IC100B.
Audio Signal Processing of Transmitter
Figure 6 Schematic Diagram for Audit Circuit of Receiver
The audio signal processing circuit of Transmitter consists of IC601 and IC609. Voice signals from
MIC are sent to VCO for modulation together with CTCSS/DCS after amplification, limitation and filtering.
IC609 is a bais band processor.
AGC circuit consists of D601, D602 and Q602,Q603. The signal amplitude is reduced to ensure no
distortion in case of oversized MIC signal.
Q601, the power switch of voice processing circuit, controlled by MCU, will give power supply to IC601
only during transmission.
J501 is the socket for external MIC, and the internal MIC will disconnect automatically when using
external MIC, but the internal PTT is still effective.

IC607 (SKY72310) is PLL integrated circuit and contains programmable parametric frequency divider
(PPFD), programmable frequency divider (PFD), phase comparator and charge pump, etc.
Low pass filter consists of R5 R7 R9 R10 C12 C15 and C18.
Reference frequency is provided by X1 (TCXO, 16.8MHz).
Reference frequency of TCXO (Temperature-controlled Crystal Oscillator) is divided by PPFD in IC607
to produce reference frequency of 5kHz or 6.25kHz (controlled by MCU based on the set channel
frequency).
The oscillation frequency of VCO is compared with reference frequency to produce error signal after
divided by PFD in IC607. The error signal is filtered by low pass filter before changing the VCO
frequency to the set value in VCO (it is locking).
N=FVCO/FR
N：Division Frequency
FVCO：VCO Oscillation Frequency
FR：Reference Frequency
Lock lost detection: When PLL is out of lock, IC pin4 will output low level signal to MCU，and then MCU
prohibit transmitter from transmitting with a warning tone.
Q8, the power filter, can provide PLL with more purified power to reduce the noise of frequency
synthesizer.

5.6 Voice Circuit：
The station is equipped with Voice Prompt Function, which is very useful during night or under dark
condition.
The speaker will voice the current channel number when changing the channel every time because of
the voice memory chip (IC613), which stores channel voice prompts. It will repeat the current channel
number once pressing “Voice Prompts”.
The speaker will voice the current channel number under standby state if the Voice Prompt Function is
set. Press “Voice Prompts” for reset to switch voice types. Press “Voice Prompts” repeatedly for power
connection, then the voice types will be switched in circle in the order of “Chinese male voice—English
male voice—Chinese female voice—English female voice—no prompts”.
5.7 Power Supply:
The station use lithium battery (7.4V, 1700mAh), while transmitter amplifier circuit (Q105 Q107) and
receiver audio amplifier (IC302) use battery directly for power supply, and other circuits use regulated
voltage (5V and 3.3V).
IC602：5C (controlled by MCU) (5V LDO)
IC603：5M 5R (controlled by MCU) (5V LDO)
IC604：5T (controlled by MCU) (5V LDO)
IC605：3.3V DC/DC
IC618：3.3V LDO, is the supply power of frequency synthesizer

DR6000-2/DR7000-2 Service Manual
CTCSS/DCS signals from MCU are sent to TCXO for modulation respectively .
CTCSS/DCS signals from receiver are sent to MCU(pin 25) for decoding, and then MCU test if there
are CTCSS/DCS signals with the same setting of the station to decide whether open the speaker or
not.
CTCSS (continuous tone control squelch system, hereinafter referred to as CTCSS), is a kind of
squelch control system with modulation on carrier and continuous sub-audio signals as pilot tone. If
CTCSS function is set, the call is available only at the same CTCSS frequency of both receiving and
transmitting parties to avoid the disturbance of other signals.
The station has 39 groups of standard CTCSS frequency for your selection, such as Table 1.
CTCSS signals produced by MCU are sent to TCXO for modulation.

DCS signaling：
DCS (Digital code squelch), is a kind of continuous digital code modulated on carrier with voice signal
and used for squelch control. If DCS function is set, the speaker is available only when receiving the
same DCS code to avoid the disturbance of useless signals.
The station has 83 kinds of standard codes including positive and inverse code for your selection, such
as Table 2.
DCS signals produced by MCU (PWM waveform) are sent to TCXO for modulation.
CTCSS/DCS signals from receiver are sent to MCU for decoding, and then MCU test if there are DCS
codes with the same setting of the station to decide whether open the speaker or not.
