Feature: 1. [RTL SDR Receiver] This RTL SDR receiver covers 100KHz to 1766MHz, supporting AM, FM (NFM, WFM), CW, DSB, LSB, USB demodulation. Ideal for listening to medium wave, short wave, FM, aviation bands, and more. (Added features: CTCSS, DCS, frequency scanner, automatic scanning, etc.) 2. [RTL2832U and R820T2 Chipset] Utilizes RTL2832U and R820T2 chipset for improved sensitivity compared to R820T, with better performance around 1.5 GHz. Fully compatible with old R820T software. Operating frequency 100KHz to 1766MHz, covering all high frequency amateur bands. 3. [0.5 PPM TCXO] Features precise tuning and minimal temperature drift, covering all HF amateur bands, VHF, and UHF frequencies from 24 to 1766MHz, with up to 3.2M sampling rate (~2.8MHz stable). Receiver modes include AM, NFM, FM, DSB, USB, LSB, and CW. 4. [Direct Sampling] Supports high frequency shortwave Q branch direct sampling (depending on SDR software used), with 8 bit ADC providing approximately 50 dB dynamic range, 50 ohm input impedance, and independent antenna inputs for shortwave and VHF. 5. [USB Computer Connection] Mini USB powered, receives low, medium, high frequencies (0 to 30MHz). HF band antenna must be connected to Ant input port, while high frequency signal reception requires compatible antennas like long wire, random wire, dipole, etc., for optimal performance.
