This machine adopts SDR architecture, if you have a strong broadcasting transmitter nearby, there may be a string of stations, mirror stations, please be aware of that.2. The input impedance of the antenna interface is 50, for medium wave radio, it is recommended to connect a special medium wave loop antenna to get a better listening effect.3. Please pay attention to the earphone (EAR) volume setting before listening to use headphones to prevent discomfort caused by excessive volume.1ULTRA LOW NOISE: This product is based on the for Tayloe Quadrature Product Detector method to realize frequency mixing, and the clock generator Si5351 generates two orthogonal square wave signals of variable frequency as the excitation, realizing an ultra low noise ZIF receiver. 2IQ SIGNAL: The IQ signal obtained after mixing is output to CODEC codec and captured by MCU, and the demodulation and display of the signal is accomplished by DSP algorithm in MCU. 3DSP DIGITAL DEMODULATION RADIO: For DeepSDR 101 is a DSP digital demodulation radio based on SDR software defined radio architecture. 4DEMODULATION FUNCTION: With 192kHz width spectrogram and waterfall display capability, together with 16bit sampling, it realizes a high dynamic receiver with CW, AM, SSB, FM demodulation function. 5ALUMINUM ALLOY: Shortwave radio receiver is made of full aluminum alloy CNC casing with 4.3 inch 800x480 resolution high brightness IPS LCD display, while maintaining a small and compact body.
