Features: The signal received by the antenna is converted into data through the receiver and sent to the computer, Android phone and other devices through the USB interface. The software on the computer, Android phone and other devices then processes and decodes the signal, displays the spectrum, and sets the reception at will. 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, , LSB, and USB demodulation. It can be used to listen to shortwave single sideband communications, FM broadcasts, walkie-talkie calls, aviation bands, meteor monitoring ADS-B decoding radar, signal reception, etc. [Analog sub-tones and digital sub-tones can be cracked through software. ] [You can set up automatic search scanning. ] [You can use software to crack the ID of commonly used digital walkie-talkies and demodulate signal] Color: gold material: metal Technical features This receiver has a built-in 1 ppm temperature compensation crystal [TCXO]. Making the frequency more stable and accurate. Almost zero temperature drift [2 ppm initial deviation, 1 ppm temperature drift] increases internal chip heat dissipation, making the work more stable. Adopting the latest RTL2832U+R820T2 solution [R820T2 tuner has slightly better sensitivity than R820T, lower noise floor, and higher signal-to-noise ratio. Can work more stably at frequencies around 1.5 GHz. ]Utilize the Q channel on RTL2832U to add direct reception of frequencies from 100KHz to 24MHz. Achieved full range reception of 100KHz-1.7GHz. Supports XP Win7, Win8, Win10, , Android and other systems.
