Why Choose Web-888
Web-888 offers 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-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 uses these projects as a showcase 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.
