This receiver features a built-in 1 ppm temperature-compensated crystal oscillator (TCXO) for improved frequency stability and accuracy. Near-zero temperature drift (2 ppm initial deviation, 1 ppm temperature drift) enhances internal chip heat dissipation, contributing to more stable operation. Equipped with the latest RTL2832U + R820T2 solution, the R820T2 tuner offers slightly better sensitivity than the R820T, with lower background noise and higher signal-to-noise ratio, enabling stable performance 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. Software on connected devices demodulates signals, displays frequency spectrum, and allows adjustable bandwidth settings, signal recording, saving, playback, and related 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 for weather monitoring, signal scanning, and more.
