This is a software-defined radio (SDR) receiver featuring the RTL2832 chip, a 0.5 ppm TCXO oscillator (customization optional), and an MCX antenna connector. It operates across a frequency range of 25 MHz to 1760 MHz. It is compatible with free SDR software applications such as SDR#, HDSDR, SDR-Radio, Linrad, GQRX, and SDR Touch for Android. The device supports Windows, macOS, Linux, Android, and embedded Linux platforms. Typical applications include wireless signal monitoring, air traffic control (ATC), ADS-B aircraft tracking, maritime AIS, ACARS, amateur radio, P25/MOTOTRBO digital voice, POCSAG paging, weather balloon telemetry, APRS, weather satellite reception, meteor satellite (e.g., M2), radio astronomy, meteor scatter detection, and DAB broadcasting. This model features an improved tuner design, enhanced component tolerances, and a stable 0.5 ppm TCXO oscillator (optional) for minimal frequency drift and high initial accuracy. A USB 2.0 port is required; compatibility with some USB 3.0 ports is possible but not guaranteed. For Windows, installation is straightforward—refer to publicly available SDR quick-start guides online. Fully assembled and ready to use. Compact size. Frequency range: 25 MHz to 1760 MHz.
