AURSINC SDR Radioberry HF SDR Transceiver Pi Hat for Raspberry Pi 4

In this review of the AURSINC Radioberry v2 SDR Pi Hat, the bottom line is simple: this board is for radio hobbyists who want a compact HF software defined transceiver built around a Raspberry Pi 4 and are comfortable with DIY setup. The Radioberry converts a Raspberry Pi into a full HF SDR transceiver using an Analog Devices AD9866 front end and an Intel Cyclone 10LP FPGA, covering 0-30 MHz with direct up and down conversion. Its biggest appeal is a native Pi-mounted radio card that runs pihpsdr or SparkSDR clients and can be extended with PA hardware for much higher transmit power.

Key Features

• Raspberry Pi integration: Directly connects to a Raspberry Pi 4 so the Raspberry supplies firmware loading and power, simplifying system assembly.
• Analog Devices AD9866 front end: A 12-bit mixed signal ADC/DAC provides broadband HF coverage for more accurate receive and transmit across 0-30 MHz.
• FPGA acceleration: Uses an Intel Cyclone 10LP (10CL025) FPGA to handle signal tasks and support the radio's modem functions.
• Multiple client support: Works with pihpsdr on the Pi desktop and SparkSDR clients on Windows, Linux, and macOS, enabling flexible control options.
• Expandable transmit power: Native output up to about 10 dBm with documented support for PA5Wv2 and external amplifiers to reach much higher power levels.
• Ready-to-run image: A provided Raspberry Pi image and supplied fan aim to make first boot and network setup straightforward for most users.

Who It's For

This board is aimed at licensed amateur radio operators and experimenters who already own a Raspberry Pi 4 and want a compact HF SDR transceiver they can control via networked SDR clients. It is a good fit for those who enjoy configuring software, experimenting with FPGA-based radio hardware, and expanding to external amplifiers for serious transmit power.

It is not ideal for complete beginners who expect out-of-the-box, worry-free reliability without any software or troubleshooting. Some customers report quality control and intermittent operation issues, so those who need guaranteed continuous duty or consumer-level support may prefer a turnkey transceiver.

Pros & Cons

Pros

• Compact Pi Hat form factor that turns a Raspberry Pi 4 into a capable HF SDR transceiver.
• High-quality AD9866 12-bit front end and FPGA provide flexible signal processing and broad 0-30 MHz coverage.
• Supports common SDR clients and can scale with external PA hardware for much higher transmit power.
• Includes a heat dissipation fan and a ready image to ease initial setup for most users.

Cons

• Some buyers reported mixed quality control and intermittent operation, so expect to troubleshoot software or hardware in a minority of units.
• Maximum receive bandwidth of 384 kHz and modest native output means serious HF contesters will likely need external amplifiers and peripherals.

Specifications

Our Verdict

The AURSINC Radioberry v2 is a focused solution for amateurs who want a Raspberry Pi based HF SDR transceiver with a modern AD9866 front end and FPGA support; it offers strong flexibility and upgrade paths at a compact price. It represents good value for tinkerers and licensed operators willing to manage software setup and occasional troubleshooting, while those needing a fully polished, plug-and-play transceiver may need a more consumer-focused option.

Frequently Asked Questions

Does this work with Raspberry Pi 4 out of the box?
Yes, a ready-to-use Raspberry Pi 4 image is provided and the board draws power and loads firmware from the Pi, making initial setup straightforward for many users.

What HF range and bandwidth does it support?
The Radioberry covers 0-30 MHz HF range with a maximum receiving bandwidth of 384 kHz and dual A/B receive modes.

Can I get more transmit power?
Yes, the card supports expansion with the PA5Wv2 power amplifier and external PAs to push output well beyond the native 10 dBm level.
