SDR 101 is a DSP digital demodulation radio based on SDR software-defined radio architecture. It has a 192kHz width spectrogram and waterfall display capabilities, and cooperates with 16bit sampling to realize a high dynamic receiver with CW, AM, SSB, FM demodulation functions. The whole machine adopts an all-aluminum alloy CNC shell, with a 4.3-inch 800x480 resolution high-brightness IPS LCD display, while maintaining a compact and compact body.
Immediately take it to the outdoors, enjoy the natural scenery and the fun of listening anytime, anywhere!
Tips uff1aOnly the frequency input function can be touched. Other functions do not support touch screen function and can only be selected by pressing the knob.

Attention points
1. The machine adopts SDR architecture. If there is a strong broadcasting station near you, the phenomenon of mirror radio may appear.
2. The input impedance of the antenna interface is 50u03a9. For the LW/MW radio, it is recommended to connect a dedicated active antenna for better listening effect.
3. Please pay attention to the volume setting of the earphone (EAR) before using the earphone to listen to avoid discomfort caused by excessive volume.
