This is a software-defined radio receiver (SDR) featuring an RTL2832 chip, 0.5 TCXO (optional customization available), and MCX connector, with a frequency range of 25 MHz to 1760 MHz. It is well-suited for use as a radio scanner with compatible free computer software such as SDR#, HDSDR, SDR-Radio, Linrad, GQRX, or SDR Touch on Android. Compatible with Windows, MacOS, Linux, Android, and embedded Linux systems, this device supports various applications including general wireless scanning, air traffic control monitoring, radio security, ADS-B aircraft tracking, marine radar, ACARS, relay radio, P25/MOTOTRBO digital voice, POCSAG, weather balloon reception, APRS, weather satellites, M2 meteor satellite, radio astronomy, meteor scatter observation, and DAB broadcasting. It also serves as a low-cost platform for amateur radio enthusiasts. This model incorporates an improved tuner design with a 0.5 ppm TCXO (optional), providing high frequency stability with minimal drift, precise initial offset accuracy, and tight temperature deviation tolerance. Enhanced component tolerances and MCX connectors contribute to reliable signal integrity. A USB 2.0 port is required for operation, though it is generally compatible with most USB 3.0 ports. Please note that compatibility cannot be guaranteed across all USB 3.0 implementations; ensure your system has a USB 2.0 port if needed.
