1、Durable: Compared with other models, it is more durable, highly stable, and has less loss. 2、Protection: Low noise PCB, improved cooling, fire protection, full band reception. 3、Applicability: Used to listen to short wave single sideband communications, FM radio, walkie talkie calls, aviation bands, meteor monitoring ADS‑B decoding radar, AIS signal reception, etc. 4、Support: Support for XP Win7, Win8, Win10, for OS, for Android and other systems. 5、Multifunction: Arbitrarily set the receiving bandwidth, signal recording, saving, playback and other functions. Item Type: Receiver Material: Aluminum Alloy Features: The signal received by the antenna is converted into data by the receiver, and sent to a computer, for Android mobile phone and other devices through the USB interface, and then processed by the software on the computer, for Android mobile phone and other devices to demodulate the signal and display the frequency spectrum. Through the SDR software, it can receive electromagnetic waves in the range of 100KHz-1.9GHz to support AM, FM (NFM, WFM), CW, DSB, LSB, and USB demodulation. It can be used to listen to short wave single sideband communications, FM radio, walkie talkie calls, aviation bands, meteor monitoring ADS-B decoding radar, AIS signal reception, etc. Technical Features: This receiver has a built-in 1 ppm temperature compensation crystal [TCXO]. Make the frequency more stable and accurate. 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. Using the latest RTL2832U, R820T2 solution [R820T2 tuner has slightly better sensitivity than R820T, lower noise floor, and higher signal-to-noise ratio. It can work more stably at frequencies around 1.7 GHz. ]Using the Q channel on the RTL2832U to increase the direct sampling reception for the frequency of 100KHz-24MHz. Achieve the full range of 100KHz-1.9GHz reception. 1 x Receiver 2 x Antenna 1 x Antenna Base
