Proven RF and ADC Design

Web-888 SDR inherits the robust RF and ADC design from RX-888, featuring a 16-bit ADC with a tunable sampling rate for superior signal fidelity.

Wide Frequency Coverage

Covering a spectrum from 1kHz to 62MHz and VHF range from 118MHz to 150MHz, the Web-888 SDR ensures comprehensive signal reception for diverse applications.

Multiple Channel Support

Simultaneously operate 13 RX channels and 13 waterfall channels, enabling extensive monitoring and analysis without the need for multiple devices.

Affordable and Reliable

Offering top-tier features at a lower price than competitors, Web-888 SDR provides exceptional value without compromising on performance and reliability.

Open Source Compatibility

Benefit from a compatible user experience with KiwiSDR and Red Pitaya Notes, supported by an active open-source community for continuous innovation and support.

Elegant and Efficient Design

A single-board design combining FPGA and CPU ensures lower power consumption, streamlined functionality, and a sleek, efficient form factor.

Clock Flexibility

Featuring a tunable frequency driver, the ADC allows for precise reference clock input and output, enhancing synchronization capabilities for advanced applications.

Web-Based User Experience

Accessible from any web browser, the Web-888 SDR offers a simple, intuitive user interface with no setup barriers, ideal for both beginners and advanced users.

Why Choose Web-888

Web-888 offers great performance at its price point. With the power of a carefully designed frontend, the power of 16-bit ADC, and the power of DSP software, it is one of the best high-performance SDRs on the market.

Web-888 is an easy-to-use web-based SDR product. You don't need to learn anything before you can start using it in your web browser. If you're looking for your first SDR device or a user-friendly SDR, choose Web-888.

Web-888 is also a great platform for skimming. The 13 channels cover all HF bands and the 6M band. We currently support FT4/FT8 skimming and WSPR skimming, with CW skimming coming in the future. If you need an SDR device for skimming across all HAM bands, choose Web-888.

We host several Red Pitaya Notes applications in the repository for users who want to do more with the Web-888 hardware. We use these projects as a showcase of how to hack Web-888 for other purposes. We also publish technical documents to support these experiments. If you're looking for an SDR platform to experiment with FPGA, HF or VHF, oversampling, or FSK transmit, choose Web-888.
