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 for XP/7/8/0, for , for Android and other systems.<br><br>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. Receives electromagnetic waves in the range of 100KHz-1.7GHz supports AM, FM (NFM, WFM), CW, , 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, AIS signal reception, etc. colour: as shown Material: ABS Size: 71x43x19mm<br><br>Package Contents: 1 x SDR Receiver 1 x Suction Cup Mount 2 x Telescopic Antennas<br><br>Only the above package content, other products are not included.
