DescriptionMeet our new SDR device, the Web-888 SDR, which an affordable and user-friendly websdr based radio receiver with pre-installed openwebrx. The 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. The Web-888 SDR covers 1kHz to 62MHz for HF band, and 118MHz to 145MHz for the VHF band. The new superior RF frontend ensures a comprehensive signal reception on both of HF and VHF bands. The Web-888 is able to operate 13 RX channels and 13 waterfall simultaneously, and this makes the extensive band monitoring and analysis possible without the need for multiple devices. The software code of Web-888 sdr is modified and built from KiwiSDR, which is supported by an active open-source community. The Web-888 comes with a neat design, a single-board receiver combining FPGA and ARM processor, and it ensures lower power consumption, web streamed audio functionality. Nevertheless, the on-board tunable frequncy driver, the precise reference clock of ADC, all of these enhances the receiver’s RF performance. Further more, the openwebrx interface make it possible for users to access the radio from any place at any time. Thanks to the subtle design of the openwebrx, you don’t need any other device to decode almost all of the digi modes by the web interface.The Web-888 sdr is housed in a palm size handy black aluminum case, with a built-in small fan for heat dissipation. The radio gives 4 SMA ports, they are HF, AIR(VHF), EXT-CLK and GPS. A gigabit ethernet port, a usb-c host port, a type-c power supply port, and a TF card slot are also given out on the other side of the receiver.
