This is a RTL SDR blog software defined radio receiver with RTL2832U ADC chip, R828D tuner, 1PPM TCXO, SMA F connector and passively cooled aluminum housing. It tunes from 500 kHz to 1.7 GHz with up to 3.2 MHz (2.4 MHz stable) bandwidth. Perfect for use as a computer based radio scanner with free software like SDR#, HDSDR, SDR-Radio, GQRX or SDR Touch on Android. Works on Windows, OSX, Linux, Android and computers like the Raspberry Pi.
Ideal for many applications including general radio scanning, air traffic control, public safety, aircraft radar, marine AIS, ACARS, log radio, P25/MotoTRBO Digital Voice, POCSAG, weather balloons, APRS, NOAA APT/Meteor M2 weather satellites, radio astronomy, DAB, or as a low cost panadapter with a ham radio.
This model has several improvements over other brands. It uses the improved R828D tuner, has an improved front end with filtering, a 1PPM TCXO, better components, a redesigned lower noise PCB, cooling improvements, additional ESD protection, and an SMA F connector. It also has a software-activatable bias-tee for feeding LNAs and active antennas. It also has HF reception capabilities. Most standard dongles can be tuned to 24 MHz minimum. This model has a built-in upconverter and allows tuning to 500 kHz. There is a built-in 28.8MHz low-pass filter to optimize this mode.
