    Product Overview
    DeepSDR 100K- 149M FM/AM/LW/MW/SW/Air-Band DSP SDR Radio Receiver + LCD Battery
    Detail
    This product realizes mixing based on the Taylor quadrant product detector method. The clock generator si5351 generates two orthogonal square wave signals with variable frequency as excitation, and realizes an ultra-low noise ZIF zero IF receiver. The IQ signal obtained after mixing is output to the codec codec and collected by MCU. The DSP algorithm in MCU completes the demodulation and display of the signal.

    Product introduction
    Deepsdr 101 is a DSP digital demodulation radio based on SDR software radio architecture. It has the ability to display spectrum and waterfall diagrams with a width of 192Khz. With 16bit sampling, it realizes a high dynamic receiver with CW, am, SSB and FM demodulation functions. The whole machine adopts an all aluminum alloy CNC shell, with a 4.3-inch 800x480 resolution bright IPS LCD display, while maintaining a compact body.
    Immediately take it outdoors and enjoy the natural scenery and the fun of radio anytime, anywhere!

    Attention:
    1. This machine adopts SDR architecture. If there is a strong radio transmitting station near you, there may be a phenomenon of connecting stations / mirror stations. Please be informed.
    2. The input impedance of the antenna interface is 50 Ω. For medium wave radio stations, it is recommended to connect a special medium wave ring antenna externally to obtain better listening effect.
    3. Please pay attention to the ear volume setting before listening with headphones to prevent discomfort caused by excessive volume.
