This receiver features a built-in 1 ppm temperature-compensated crystal oscillator (TCXO) for enhanced frequency stability and accuracy. With minimal temperature drift (2 ppm initial deviation, 1 ppm temperature drift), it improves internal chip heat dissipation and ensures stable operation. Utilizing the latest RTL2832U + R820T2 solution, the R820T2 tuner offers improved 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 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. Software on connected devices processes the demodulated signal, displays the frequency spectrum, and allows adjustable bandwidth settings, signal recording, saving, playback, and related functions. Supports reception of AM, FM (NFM, WFM), CW, LSB, and USB modulation within the 100 kHz to 1.7 GHz range. Suitable for shortwave SSB communications, FM radio, walkie-talkie signals, aviation bands, ADS-B decoding for meteor monitoring, and general signal reception.
