Feature: 1. Software Defined Radio (SDR) is a new type of radio broadcast communication technology based on software-defined wireless communication protocols rather than hardwired. 2. Bands, air interface protocols and functions can be upgraded through software downloads and updates without need to completely replace the hardware. 3. 100KHz-1.7GHz full-band RTL-SDR receiver can be connected to computers, for Android phones and other devices. 4. Use SDR software to receive 100KHz-1.7GHz electromagnetic waves to support AM, FM(NFM, WFM), CW, DSB, LSB, USB demodulation. 5. Can listen to medium wave, short wave, FM radio, short wave single sideband communication, two-way radio call, aviation band and so on. (Add mute detection function: CTCSS, DCS; frequency sweeper, automatic scanning, etc).
