Feature: 1. Good Chip Set: Designed to have RTL2832U and R820T2 set with better sensitivity, lower noise floor and higher signal to noise ratio. 2. Better Design: The Q channel on the RTL2832U is used to increase the direct sampling and reception of the frequency of 100KHz‑24MHz. 3. Broader Range: Able to realize a full range of 100KHz‑1.7GHz reception, and can also work more stably at frequencies around 1.5 GHz. 4. Reliable Work: This receiver has built in 1 ppm temperature compensated crystal TCXO, making the frequency more stable and accurate. 5. Easy to Install: Light in weight and compact in size, the simple carrying and installation will largely simplify your work. Specification: Item Type: RTL SDR USB Receiver Material: Aluminium Colour: Silver Features: 1. The signal received by the antenna is converted into data through the receiver, sent to the computer, mobile phone and other devices through the USB interface, and then processed by the software on the computer, mobile phone and other devices to demodulate the signal, and display the spectrum, set to receive bandwidth, signal recording, saving, playback and other functions. 2. Through SDR software, receiving electromagnetic waves in the range of 100KHz-1.7GHz supports AM, FM (NFM, WFM), CW, DSB, LSB, USB demodulation. It can be used to listen to short wave single side band communication, FM radio, calls, aviation band, meteor monitoring ADS-B decoding radar, AIS signal reception, etc. 3. The analogue sub tones and digital sub tones can be cracked through the software. 4. You can set automatic search scans. 5. The ID of common digital devices can be cracked and the voice signal can be demodulated by software. .
