This receiver features a built-in 1 ppm temperature-compensated crystal oscillator (TCXO), ensuring more stable and accurate frequency performance. With minimal temperature drift (2 ppm initial deviation, 1 ppm temperature drift), it enhances internal chip heat dissipation for improved operational stability. It utilizes the latest RTL2832U + R820T2 solution, where the R820T2 tuner offers slightly better sensitivity than the R820T, with lower background noise and a higher signal-to-noise ratio. This allows for more stable operation 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 signal received by the antenna is converted into data by the receiver and transmitted to computers, Android phones, and other devices via the USB interface. Software on these devices processes the demodulated signal, displays the frequency spectrum, and allows users to set reception bandwidth, record signals, save data, and play back recordings. Supports reception of electromagnetic waves in the 100 kHz to 1.7 GHz range, with AM, FM (NFM, WFM), CW, LSB, and USB demodulation capabilities. Ideal for listening to shortwave single-sideband communications, FM radio, walkie-talkie transmissions, aviation bands, ADS-B signal decoding for weather monitoring, and general signal reception.
