The HT004A LNA is designed to boost weak signals across a wide frequency range, enhancing the receiver's performance.
Package Contents
Please verify that all items listed below are included in your package:
- 1 x HTOOL SDR V5 DSP SDR Radio Receiver
- 1 x Antenna (telescopic)
- 1 x Data Cable (USB Type-C)
- 1 x Double-ended Touch Screen Pen
- 2 x Adapters (likely for antenna connection)
- 1 x HTOOL HT004A Low Noise Amplifier
Setup
- Charging the SDR V5 Radio: Connect the provided USB Type-C data cable to the 'Type-C Charging' port on the top of the SDR V5 radio and to a 5V USB power source. The device has a built-in 3000mAh 3.7V battery.
- Attaching the Antenna: Screw the telescopic antenna into the BNC male antenna interface on the SDR V5 radio. Ensure it is securely fastened.
- Connecting the HT004A Low Noise Amplifier (Optional):
- Connect the antenna to one end of the HT004A LNA.
- Connect the other end of the HT004A LNA to the BNC male antenna interface of the SDR V5 radio using one of the provided adapters if necessary.
- Ensure the HT004A LNA is powered. It requires a 5V 1A power supply. The LNA has a switch labeled USB/BAT on its bottom side.
- Powering On: Locate the ON/OFF switch on the top of the SDR V5 radio and slide it to the 'ON' position.
Operating Instructions
- Screen and Navigation: The SDR V5 features a 4.3-inch 800x480 resolution high-brightness IPS capacitive touch screen. Use the included stylus or your finger for navigation.
- Frequency Tuning: Use the rotary encoder on the right side of the radio to adjust the frequency. The step frequency can be set to 1Hz, 10Hz, 100Hz, 1kHz, 10kHz, 100kHz, 1MHz, or 10MHz.
- Demodulation Modes: The radio supports CW (Continuous Wave), AM (Amplitude Modulation), SSB (Single Sideband), FM (Frequency Modulation), and WFM (Wideband Frequency Modulation) demodulation functions. Select the desired mode via the touch screen interface.
- Spectrum and Waterfall Display: The 192kHz wide spectrum and waterfall graph display provide a visual representation of the radio signals. This feature helps in identifying and tuning into signals more effectively.
- Preset Channels: Up to 99 channels can be preset. You can set the station name, frequency, and demodulation method for each preset.
- Audio Output: Connect standard 3.5mm headphones or CTIA (American standard) interface headphones to the audio jack on the side of the device for private listening. The internal speaker provides up to 3W output.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Avoid using abrasive cleaners or solvents. For the screen, use a screen-specific cleaning solution and a microfiber cloth.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge the device regularly, even if not in use for extended periods. Store the device in a cool, dry place.
- Storage: When not in use, store the SDR V5 Radio and HT004A LNA in a protective case to prevent dust and physical damage.
- Antenna: Handle the telescopic antenna with care to avoid bending or breaking.
Troubleshooting
- No Power: Ensure the battery is charged. Connect the device to a power source using the USB Type-C cable. Check the ON/OFF switch position.
- Poor Reception: Extend the antenna fully. Ensure the antenna is securely connected. If using the HT004A LNA, ensure it is properly connected and powered. Try adjusting the gain settings on the SDR V5 if available, or ensure the LNA is functioning.
- No Audio: Check headphone connection. Ensure volume is not muted or set too low. If using external speakers, verify their connection and power.
- Screen Unresponsive: Use the stylus for more precise touch input. If the screen remains unresponsive, try restarting the device.

User Tips
- For optimal signal reception, especially for weaker signals, ensure the telescopic antenna is fully extended and positioned away from potential interference sources.
- When using the HT004A LNA, remember to power it separately to achieve the advertised gain. This is crucial for improving signal strength in noise-sensitive applications.
- Experiment with different demodulation modes (CW, AM, SSB, FM, WFM) to find the best clarity for the signal you are trying to receive.
- Utilize the 99 preset channels to quickly access your favorite stations or frequencies. Naming them can help with organization.
- The touch screen is responsive; use the provided stylus for more precise control, especially when navigating menus or setting fine frequency adjustments.
