This is a software-defined radio receiver (SDR) with RTL2832 chip, 0.5 TCXO (customization optional), and MCX connector, featuring a bandwidth between 25 MHz and 1760 MHz. It is well-suited for use as a radio scanner with 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 radar, marine radar, ACARS, relay radio, P25/MOTOTRBO digital voice, POCSAG, weather balloon tracking, APRS, weather satellite reception, M2 meteor satellite, radio astronomy, meteor scatter monitoring, and DAB broadcasting. It can also serve as a low-cost platform for traditional ham radio use. This model features an improved tuner design with 0.5 TCXO (optional customization), providing stable frequency output with no drift, high initial offset accuracy, and a temperature deviation of ±0.5 ppm. Enhanced component tolerances and MCX connectors contribute to improved performance and durability. A USB 2.0 port is required for operation, though it may work with most USB 3.0 ports (note that compatibility cannot be guaranteed on all USB 3.0 ports; ensure your computer has a USB 2.0 port if needed).
