Malachite DSP SDR 1.10d Radio Receiver V5

1. Introduction

The Malachite DSP SDR Receiver V5 is a software-defined radio designed for versatile communication functions. This 2023 model (V5) features a robust CNC aluminum casing, an integrated 4Ω 5W full-range speaker, and a high-capacity 3.7V 5000mAh lithium battery. It includes a single antenna port with automatic switching between 50 ohm and high-impedance input modes, a built-in RF preamplifier, and a 0-30dB program-controlled RF attenuator. The V5 also incorporates a 20mm diameter large dial encoder for enhanced usability.

Malachite receivers operate on the SDR principle, allowing different communication functions to be realized by loading various software configurations onto a general hardware platform.

4. Controls and Interfaces

1. Antenna: Standard SMA female connector. Automatically switches between 50Ω and high-Z mode. For frequencies ≤ 50MHz, High-Z mode is used for LW, MW, and SW. For frequencies > 50MHz, a 50 ohm impedance input is used.
2. Headphone: The audio output is connected to a 3.5mm headphone jack.
3. Standby/Power Button: In standby mode, short press to power on. Short press to turn the screen on or off. Press and hold to enter standby mode while powered on.
4. Charging LED: A red light indicates charging is in progress. A green light indicates charging is complete.
5. TYPE-C Port: Used for charging and USB communication functions. Connect the unit to a computer to use with HDSDR software.
6. Touch Screen Control Area: This area provides detailed control operations. Please refer to the electronic manual for comprehensive instructions on touch screen usage.
7. Volume Encoder (ENC): Used to set volume, attenuation, audio filter, and other related parameters.
8. Frequency Encoder (ENC): Used to set the receiving frequency, step value, and other frequency-related parameters.

5. Initial Setup

1. Charge the Device: Before first use, fully charge the receiver using the provided TYPE-C cable and a 5V/1A power adapter. The charging LED will be red during charging and turn green when complete.
2. Attach Antenna: Screw the telescopic antenna securely into the SMA female connector on the top of the receiver. Ensure it is finger-tight.
3. Power On: Press and hold the power button (3) until the screen illuminates.
4. Initial Configuration: The device may prompt for initial language or time settings. Follow the on-screen instructions.

6. Operation

The Malachite DSP SDR V5 offers a wide range of functions accessible via its capacitive touch screen and mechanical encoders.

6.1 Basic Tuning

• Frequency Adjustment: Use the Frequency Encoder (8) to change the receiving frequency. Rotate clockwise to increase, counter-clockwise to decrease.
• Volume Control: Adjust the audio output level using the Volume Encoder (7).
• Mode Selection: Tap the 'MODE' button on the touch screen to cycle through available modulation types (AM, SSB, DSB, CW, NFM, WFM).
• Band Selection: Tap the 'BAND' button to select predefined frequency bands or access band pages.

6.2 Advanced DSP Functions

The touch screen interface provides access to various Digital Signal Processing (DSP) functions:

• HARD: Access hardware-related settings.
• AUDIO: Adjust audio filters and equalizer settings.
• VISUAL: Configure display options and spectrum/waterfall settings.
• NR (Noise Reduction): Activate adaptive squelch for noise reduction.
• NB (Noise Blanker): Engage the noise canceller to reduce pulse noise.
• AGC (Automatic Gain Control): Manage automatic gain control settings for stable signal levels.
• ANF (Automatic Notch Filter): Enable the automatic notch filter to remove interfering tones.

For detailed control operations and advanced settings, please refer to the comprehensive electronic manual available for download.

7. User Tips

• Screen Noise: Some users have reported screen noise when the display is active. If you experience this, try reducing screen brightness or using headphones for a clearer audio experience.
• Optional Board: The V5 model comes with an integrated 'optional board' which provides enhanced functionality, including 50 ohm and Hi-Z input switching, a built-in RF attenuator, and additional band-pass filters. This means these features are standard on your V5 unit.
• External Antenna: For optimal reception, especially on lower frequencies or in areas with weak signals, consider using a high-quality external antenna connected to the SMA port.
• Software Updates: Check the official product page or community forums for firmware updates to ensure you have the latest features and performance improvements.

8. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Avoid using harsh chemicals or abrasive materials. For the screen, use a microfiber cloth specifically designed for electronics.
• Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Store the device in a cool, dry place when not in use for extended periods.
• Storage: When storing the receiver, especially during travel, use the provided EVA hard shell protection bag to prevent damage.
• Antenna Care: Handle the telescopic antenna gently to avoid bending or breaking. Retract it when not in use.

9. Troubleshooting

• Device Not Powering On: Ensure the battery is charged. Connect the TYPE-C cable to a power source and check if the charging LED illuminates. If not, try a different cable or power adapter.
• No Audio Output: Check the volume level using the Volume Encoder (7). Ensure headphones are properly plugged into the 3.5mm jack if used. Verify that the correct modulation mode is selected.
• Poor Reception: Extend the telescopic antenna fully. Try repositioning the receiver or moving to an area with better signal. Ensure the antenna connection is secure. If using an external antenna, verify its connection and functionality.
• Screen Noise: If you experience noise when the screen is on, try reducing the screen brightness. Using headphones can also help isolate audio from potential screen interference.
• Touch Screen Unresponsive: If the touch screen is unresponsive, try restarting the device by holding down the power button until it turns off, then power it back on.
• USB Connection Issues: Ensure the TYPE-C cable is properly connected to both the receiver and the computer. Verify that the necessary drivers for HDSDR software are installed on your computer.
