Features: The receiver is based on the SDR principle architecture and its functions are determined by the loaded software. All types of ana-log modulation: AM，SSB，NFM，WFM, CW and the frequency ranges is 50K~2GHz. Multifunctions: variable filter width, adaptive noise suppressor, threshold noise suppressor, noise blanker, AGC, equalizer. Adopt the multi-function chip msi001, and the powerful STM32H743VIT6 with a clock frequency of 480 MHz is used. Connect to com-puter via USB, which can transfer CA-T, IQ and audio, with 160kHz span, with scalability. Built-in add-on board with source follower, and also with the backlight function, giving you a better experience. Compare with the other type, this SDR receiver add the functions of IQ can be adjust by manual, the bandwidth of the filter can be automatically changed in CW mode, DSB double-sideband modulation and AM det synchronous detection wa-ve functions.
