1、The signal received by the antenna is converted into data by this receiver and sent to the computer, for Android phone and other devices through the USB interface. The software on the computer and for Android phone and other devices processes the demodulated signal and displays the spectrum. Set the receiving bandwidth, signal recording, saving, playback and other functions. 2、Receive the electromagnetic waves in the range of 100KHz-1.7GHz through SDR software. Support AM, FM NFM, WFM, CW, DSB, LSB, USB demodulation. 3、Can be used to listen to short waves single-sideband communication, FM radio, intercom calls, aviation bands, meteor monitoring ADS-B decoding radar, AIS signal reception, etc. 4、The analog subtone and digital subtone can be cracked by software. 5、Can set automatic search scan. 6、The ID of common digital walkie-talkies can be cracked and demodulated by software. 7、Built-in 1 ppm temperature compensation crystal TCXO. Make the frequency more stable and accurate. 8、The almost zero temperature drift initial deviation of 2 ppm, temperature drift of 1 ppm increases the internal chip heat dissipation, making the work more stable. 9、The latest RTL2832U + R820T2 solution is used R820T2 tuner has slightly better sensitivity than R820T, lower background noise and higher signal-to-noise ratio. It can work more stably at frequencies around 1.5 GHz. 10、The Q channel on the RTL2832U is used to increase the direct receiving of the frequency of 100KHz-24MHz. Achieved 100KHz-1.7GHz full segment reception. 11、Support for XP, for Win7, for Win8, for Win10, for MAC, for Android and other systems.
