Get! For RTL-SDR Blog RTL SDR V4 R828D RTL2832U 1PPM TCXO SMA RTLSDR Software Defined Radio (Dongle Only) This is an RTL SDR blog software defined radio receiver with RTL2832U ADC chip, R828D tuner, 1PPM TCXO, SMA F connector and aluminium case with passive cooling. Tunes from 500 kHz to 1.7 GHz with up to 3.2 MHz (2.4 MHz stable) of bandwidth._x000D_ Perfect for use as a computer based radio scanner with free software like for SDR#, for HDSDR, for SDR-Radio, for GQRX or for SDR Touch on for Android. Works on Windows, OSX, Linux, Android and Computers like The for Raspberry Pi._x000D_ Great for many applications including general radio scanning, air traffic control, public safety, for ADS-B aircraft radar, for marine AIS, for ACARS, for trunked radio, for P25/MotoTRBO digital voice, for POCSAG, for weather balloons, for APRS, for NOAA APT/ Meteor M2 weather satellites, radio astronomy, DAB, or as a low cost panadapter with a ham radio._x000D_ This model has several improvements over other s. 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, extra ESD protection and an SMA F connector._x000D_ It also has a software activatable bias-tee for powering LNA's and active antennas. It also has HF reception capabilities. Most standard RTL-SDR dongles can tune down to 24 MHz at the lowest. This model has a built in upconverter, and allows for tuning down to 500 kHz. There is a built in 28.8 MHz low pass filter for optimizing this mode._x000D_ _x000D_ Please note, this is the new V4 unit and not all software is compatible with it yet! Compatibility with most programs on Windows and Linux is now OK, but for MacOS and for Android is still catching up._x000D_ Colour:Photo Color_x000D_ Material:plastic_x000D_ _x000D_ Package Contents:_x000D_ 1 x Radio Receiver_x000D_ _x000D_ Only the above package content, other products are not included._x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
