This receiver features a built-in 1 ppm temperature-compensated crystal oscillator (TCXO) for improved frequency stability and accuracy. With nearly zero temperature drift (2 ppm initial deviation, 1 ppm temperature drift), it enhances internal chip heat dissipation, ensuring stable operation. Equipped with the latest RTL2832U + R820T2 solution, the R820T2 tuner offers better sensitivity, lower background noise, and a higher signal-to-noise ratio compared to the R820T. It performs reliably at frequencies around 1.5 GHz. The Q channel on the RTL2832U enables enhanced 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 receiver converts antenna signals into data and transmits them to computers, Android phones, and other devices via USB interface. Compatible software processes the demodulated signal, displays the frequency spectrum, and allows adjustable bandwidth settings, signal recording, saving, playback, and more. Receives electromagnetic waves in the 100 kHz to 1.7 GHz range and supports AM, FM (NFM, WFM), CW, LSB, USB demodulation. Ideal for shortwave SSB communications, FM radio, walkie-talkie signals, aviation bands, ADS-B decoding, meteor monitoring, and general signal reception.
