This receiver features a built-in 1 ppm temperature-compensated crystal oscillator (TCXO) for improved frequency stability and accuracy. Minimal temperature drift (2 ppm initial deviation, 1 ppm temperature drift) enhances internal chip heat dissipation, ensuring stable operation. Utilizes the latest RTL2832U + R820T2 solution; the R820T2 tuner offers better sensitivity, lower background noise, and higher signal-to-noise ratio compared to R820T, providing more stable performance at frequencies around 1.5 GHz. The Q channel on the RTL2832U enables direct sampling reception from 100 kHz to 24 MHz, achieving full-band coverage from 100 kHz to 1.7 GHz. Compatible with Windows XP/7/8/10, Android, and other supported systems. The antenna signal is converted into data by the receiver and transmitted to computers, Android phones, and other devices via USB interface. Software on these devices processes the demodulated signal, displays the frequency spectrum, and allows adjustable bandwidth settings, signal recording, saving, playback, and other functions. Receives electromagnetic waves in the 100 kHz to 1.7 GHz range and supports AM, FM (NFM, WFM), CW, LSB, USB demodulation modes. Ideal for receiving shortwave SSB communications, FM radio, walkie-talkie transmissions, aviation bands, ADS-B signals for aircraft tracking, weather satellite monitoring, and general signal reception.
