The AURSINC Radioberry Preamp Board V2 is an amplification module designed to enhance the capabilities of your Radioberry SDR setup, transforming it into a compact QRP (low-power) radio. This board provides HF power output ranging from 3W to 5W, suitable for driving larger HF amplifiers (10W-100W PA). It is specifically engineered for seamless integration with Raspberry Pi 4 and 4B boards, combining digital signal processing with radio functionality in a small form factor. The V2 version offers improved output power compared to its predecessor.

3. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും
The Radioberry Preamp Board V2 is designed for straightforward integration with your Raspberry Pi 4 or 4B and Radioberry board. Follow these steps for proper setup:
- മൗണ്ടിംഗ്: Carefully align the Radioberry Preamp Board V2 with your Radioberry board and Raspberry Pi. Use the provided plastic columns, screws, and nuts to securely stack and fasten the boards together. Ensure all pins are correctly aligned before applying pressure.
- പവർ കണക്ഷൻ: Connect the 8V battery-powered wire to the designated power input on the preamp board. The preferred input voltage is 8.4V, with a range of 6-8V supported.
- SMA Cable Connections:
- Connect one SMA cable from the Radioberry's transmit (Tx) output to the "HF Power In" port on the preamp ബോർഡ്.
- Connect another SMA cable from the preamp board's "HF Power Out" port to your antenna or subsequent HF ampജീവൻ.
- Connect the third SMA cable for the receive (Rx) path as required by your specific Radioberry setup.
- PTT/Mic Connection: If using a PTT (Push-To-Talk) or microphone, connect it to the appropriate jack on the preamp ബോർഡ്.

Once the hardware is set up, configure your software for optimal performance. The board supports SSB, FM, and AM modes across an RF range of 1MHz to 50MHz.
4.1. Software Configuration (SparkSDR Exampലെ)
For software-defined radio applications like SparkSDR, specific settings are required to enable and utilize the preamp board's amplification capabilities:
- Enable PA: Navigate to the Radio Settings within SparkSDR. Under the "PA" or "Power Amplifier" tab, ensure the "Enable PA" option is checked.
- Adjust Drive and Hang Time: In the General Radio Settings, locate and adjust the "drive" and "PTT hang time" parameters as needed for your specific operation and desired output.

For prolonged continuous transmission, it is crucial to adjust the bias voltage. A safe range for the bias voltagഇ ആണ് 2.4V–2.5V. Refer to the schematic diagram or specific documentation for the exact adjustment points on the board.
5. Maintenance and Best Practices
To ensure the longevity and optimal performance of your Radioberry Preamp Board V2, consider the following maintenance tips:
- താപ വിസർജ്ജനം: For better performance and to prevent overheating during prolonged use, especially with continuous transmission modes, it is highly recommended to add a small fan for active heat dissipation.
- ബയാസ് വോളിയംtagഇ നിരീക്ഷണം: Regularly monitor and adjust the bias voltage to stay within the recommended 2.4V–2.5V range, particularly if you engage in extended transmission periods.
- ശുചിത്വം: Keep the board free from dust and debris. Use compressed air or a soft brush for cleaning.
6. പ്രശ്നപരിഹാരം
If you encounter issues with your Radioberry Preamp Board V2, consider the following troubleshooting steps:
- No Power Output/Ampഉയർത്തൽ:
- Verify all power connections and ensure the input voltage is within the 6-8V (8.4V preferred) range.
- Check SMA cable connections for proper seating and continuity.
- Confirm that the "Enable PA" option is activated in your SDR software (e.g., SparkSDR).
- Inspect the board for any visible damage or loose components.
- Software Display Issues (e.g., "Weird Rainbow", "Dead Waterfall"):
- Ensure you are using the correct and compatible software version for your Radioberry and preamp ബോർഡ്.
- Try reinstalling the SDR software or even the Raspberry Pi operating system if issues persist.
- Refer to the official Radioberry documentation and community forums for specific software configuration guides.
- അമിത ചൂടാക്കൽ:
- Ensure adequate ventilation around the board.
- Install a small cooling fan as recommended in the Maintenance section.
- Check and adjust the bias voltage to the safe range of 2.4V–2.5V.
