This is a software-defined radio (SDR) receiver featuring the RTL2832 ADC chip, a 0.5 ppm TCXO (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. Typical applications include wireless signal monitoring, air traffic control (ATC), ADS-B aircraft tracking, marine VHF, ACARS, trunked radio systems, P25/MOTOTRBO digital voice, POCSAG paging, weather balloon telemetry, APRS, weather satellite reception, meteor satellite (M2) reception, radio astronomy, meteor scatter detection, and DAB broadcasting. It also serves as an affordable platform for amateur radio experimentation. This model features an improved ADC architecture and tuner design, enhanced component tolerances, and a high-quality MCX connector with gold plating for durability and low insertion loss. 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 - Enclosure material: ABS - Color: Blue Package includes: - 1 x SDR receiver Note: Color appearance may vary slightly due to screen settings and lighting conditions.
