This is a software-defined radio (SDR) receiver featuring the RTL2832 ADC 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 such as SDR#, HDSDR, SDR-Radio, Linrad, GQRX, and SDR Touch for Android. The device supports Windows, macOS, Linux, Android, and embedded Linux platforms. Applications include general wireless scanning, air traffic control (ATC), ADS-B aircraft tracking, maritime AIS, ACARS, repeater monitoring, P25/MOTOTRBO digital voice, POCSAG, weather balloon telemetry, APRS, weather satellite reception, meteor satellite reception (e.g., M2), radio astronomy, meteor scatter detection, and DAB. It also serves as an affordable platform for amateur radio experimentation. This model features an improved ADC architecture and enhanced tuner design, with tighter component tolerances and a stable 0.5 ppm TCXO (initial offset accuracy ±0.5 ppm over temperature). A USB 2.0 port is required; compatibility with some USB 3.0 ports is possible but not guaranteed. Windows installation is straightforward—refer to publicly available SDR quick-start guides for setup instructions. - Fully assembled and ready to use - Compact form factor - Frequency range: 25 MHz to 1760 MHz (covers VHF and UHF bands) - Reception modes: AM, NFM, FM, USB, LSB, CW - Gold-plated MCX antenna connector for durability and low insertion loss - Housing material: ABS - Color: Blue Package includes: - 1 x SDR receiver Note: Color appearance may vary slightly due to screen settings and lighting conditions.
