Can set automatic search scan. The analog subtone and digital subtone can be cracked by software. The ID of common digital walkie-talkies can be cracked by software and the voice signal can be demodulated. The signal received by the antenna is converted into data by this receiver and sent to the computer, Android phone and other devices through the USB interface. The software on the computer and Android phone and other devices processes the demodulated signal, displays the frequency spectrum, and arbitrarily sets the reception. Bandwidth, signal recording, saving, playback and other functions. Through SDR software, receiving electromagnetic waves in the range of 100KHz-1.7GHz supports AM, FM(NFM, WFM), CW, DSB, LSB, USB demodulation. Can be used to listen to short-wave single-sideband communications, FM radio, intercom calls, aviation bands, meteor monitoring ADS-B decoding radar, AIS signal reception, etc. Technical characteristics: This receiver has a built-in 1 ppm temperature compensation crystal [TCXO]. Make the frequency more stable and accurate. The almost zero temperature drift [2 ppm initial deviation, 1 ppm temperature drift] increases the internal chip heat dissipation, making the work more stable. Using the latest RTL2832U + R820T2 solution R820T2 tuner has slightly better sensitivity than R820T, lower background noise and higher signal-to-noise ratio. Can work more stably at frequencies around 1.5 GHz. The Q channel on the RTL2832U is used to increase the direct mining reception of the frequency of 100KHz-24MHz. Achieved 100KHz-1.7GHz full segment reception. Support XP Win7, Win8, Win10, MAC, Android and other systems. Applicable: XP Win7, Win8, Win10, MAC,Android And Other Systems. Material: Metal colour: silver Package Contents: 2 x TCXO RTL SDR Receiver
