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

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.

TX VCO Unit consists of Q4 D2 D4 L14 C35 C41 C44 and C45,D5 is the modulation circuit of VCO.

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).

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.
