What is Web-888 SDR?

The Web-888 SDR, featuring a Web based user interface and a new RF frontend and FPGA implementation, is a cutting-edge SDR product utilizing 16-bit ADC sampling and covering a frequency band up to 62MHz.

Powered by the Zynq7010 FPGA with dual A9 ARM cores, a FPGA implementation and highly optimized server software, theWeb-888leverages a fast in-chip bus to deliver 13 channels with waterfall enabled for all channels.

Why Choose Web-888

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

Web-888is 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, chooseWeb-888.

Web-888is 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, chooseWeb-888.

We host several Red Pitaya Notes applications in the repository for users who want to do more with theWeb-888hardware. We uses these projects as a showcase how to hackWeb-888for 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, chooseWeb-888.
