Description:
The Malachite receiver is built according to the SDR principle, relatively general hardware platform, by loading different software to realize different communication functions.

Features:
- Aluminum housing with CNC machining
- Built-in 4Ω 3W dual speakers
- 3.7V 8000mAh lithium battery and an independent switch for the battery
- Single antenna port design, supporting automatic switching between 50 ohm and high impedance input modes
- Built-in RF preamplifier and 0-30dB programmable RF attenuator make this SDR radio receiver more convenient and practical

Specifications:
1. Frequency range: 10kHz-250MHz, 400MHz-2GHz
2. Spectrum width: 160kHz, 80kHz, 40kHz
3. Modulation type: AM, SSB, DSB, CW, NFM, WFM (stereo RDS support)
4. Sensitivity: 0.3uV up to 1GHz
5. Dynamic range: 82dB
6. Antenna interface: single antenna port design; standard SMA female gold-plated connector; 50 ohm and high impedance input mode automatic switching; built-in RF preamplifier and 0-30dB program-controlled RF attenuator
7. Battery capacity: built-in 3.7V 8000mAh lithium battery, independent battery switch, cut off the battery power when not in use for a long time
8. Software DSP functions: variable filter width, adaptive noise regeneration (NR), threshold squelch, noise blanker (NB), automatic gain control (AGC), automatic notch filter (ANF), RDS support stereo FM, analog stereo, equalizer
9. Hardware features: STM32H743 CPU (for ARM) at 480MHz, MSi001 multi-band and multi-mode tuner, 3.5-inch 480x320 LCD display, capacitive touch screen, two mechanical encoders

Package Included:
- 1 x Main Unit
- 1 x Quick Start Guide



1. Antenna interface: gold-plated connector (SMA female); automatically switch between 50 ohm and high impedance input modes. ≤50MHz, using high-impedance input, suitable for long-wave, medium-wave and short-wave programs; >50MHz, use 50 ohm impedance input.
2. Headphone jack: The audio output is connected to the 3.5mm headphone jack.
3. Standby button: In the power-on state, short press the button to turn off the screen. Short press the button again to turn on the screen. In the power-on state, long press the button to enter standby mode. Short press the button again to exit standby mode.
4. Charging indicator light: red light is on during charging, and the light is off when charging is complete.
5. TYPE-C port: for charging and USB communication. Connect the SDR radio to a computer to use with software for HDSDR.
6. Power switch: an independent power switch that controls the battery. ON means connecting the battery. OFF means disconnecting the battery. Note: The switch must be turned ON when charging, and the switch must be turned OFF when not in use for a long time to cut off the battery power and prevent the battery from running out of power.
7. Volume knob: set parameters such as volume, attenuation, audio filter, etc.
8. Frequency knob: set frequency value, step value and other parameters.
