This receiver features a built-in 1 ppm temperature-compensated crystal oscillator (TCXO), ensuring enhanced frequency stability and accuracy. With nearly zero temperature drift (2 ppm initial deviation, 1 ppm temperature drift), it improves internal chip heat dissipation for more stable operation. Equipped with the latest RTL2832U + R820T2 solution, the R820T2 tuner offers slightly better sensitivity than the R820T, lower background noise, and a higher signal-to-noise ratio, enabling 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 receiver converts antenna signals into data and transmits them to computers, Android phones, and other devices via USB interface. Compatible software processes demodulated signals, displays frequency spectrum, and allows users to set reception bandwidth, record, save, and playback signals. Supports reception of electromagnetic waves in the 100 kHz to 1.7 GHz range, with AM, FM (NFM, WFM), CW, LSB, and USB demodulation modes. Ideal for receiving shortwave SSB communications, FM radio, walkie-talkie transmissions, aviation bands, ADS-B signals for weather monitoring, and general signal reception.
