This model uses a ADC RTL solution and an improved tuner. It features a 0.5 PPM TCXO ( optional) offering low drift, with initial offset accuracy and 1 PPM temperature deviation, increased part tolerances, and MCX connectors. Compatible across MacOS, Linux, Android and embedded Linux computers. Suitable for a wide range of applications, including general wireless scanning, air traffic control, radio security, ADSB aircraft radar, radar, ACARS, relay radio, P25/MOTOTRBO digital voice, POCSAG, weather balloon, APRS, weather satellite APT, M2 meteor satellite, radio astronomy, meteor scattering monitoring, or as a lowcost platform for traditional ham radio. This is a RTLSDR softwaredefined radio receiver based on the RTL2832 ADC chip, with a 0.5 PPM TCXO ( optional) and MCX connector, offering a bandwidth from 25 MHz to 1760 MHz. It is very suitable as a radio scanner with computer software such as SDR, HDSDR, SDRRadio, Linrad, GQRX or SDR Tap on Android.
