DR6000-2/DR7000-2 Service Manual Chapter 5 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 4 harmonics of 16.8MHz of crystal oscillator X1 TCXO.

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).

DR6000-2/DR7000-2 Service Manual 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.
Page 25
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.
