4.3" Software Defined Radio SDR Radio Receiver 100K-149MHz Digital Demodulation Short Wave FM MW SSB CW HAM DSP Receiver

Description:

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 ：Only the frequency input function can be touched. Other functions do not support touch screen function and can only be selected by pressing the knob.
