This receiver features a built-in 1 ppm temperature-compensated crystal oscillator (TCXO), ensuring enhanced frequency stability and accuracy. With minimal 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 improved sensitivity compared to the R820T, lower background noise, and a higher signal-to-noise ratio, enabling reliable performance at frequencies up to 1.5 GHz. The Q channel on the RTL2832U enhances direct sampling reception from 100 kHz to 24 MHz, providing wide frequency 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, smartphones, and other devices via USB interface. Compatible software enables signal demodulation, frequency spectrum display, adjustable bandwidth settings, signal recording, saving, playback, and related functions. Supports reception of AM, FM (NFM, WFM), CW, LSB, USB modulation modes across 100 kHz to 1.7 GHz. Ideal for shortwave SSB communications, FM radio, walkie-talkie signals, aviation bands, ADS-B weather monitoring, and signal scanning. Color: As shown. Material: ABS. Dimensions: 71 x 43 x 19 mm.
