Nooelec NESDR Mini USB RTL-SDR & ADS-B Receiver Set, RTL2832U & R820T Tuner, MCX Input. Low-Cost Software Defined Radio Compatible with Many SDR Software Packages. R820T Tuner & ESD-Safe Antenna Input

The perfect device for learning software defined radio, on the cheap. Amateur radio, ADS-B, police & fire scanning, trunking, satellite images–you name it, this little guy can probably do it. Outperforms many devices 10x its cost! These units are based on the R820T tuner IC made by Rafael Micro. As such, they have a frequency capability of approximately 27MHz-1700MHz, though this can vary somewhat from unit to unit. There is also an RTL2832U IC on board of course, which acts as the demodulator and USB interface. The connector type on the antenna and USB board is MCX–male MCX on the antenna, female MCX on the SDR. We perform extensive QA on every batch sold. As with all our SDRs, we guarantee antenna protection will be present so that your new investment will not be quickly destroyed by spurious ESD. SOFTWARE DETAILSFull compatibility with a large array of software packages, such as MATLAB, HDSDR, SDR Touch, SDR#, Planeplotter–too many to list. MathWorks and Nooelec have coordinated to bring MATLAB support for our SDR receivers. The RTL-SDR radio support package enables you to design wireless receivers using real world signals. Using Communications System Toolbox in conjunction with an RTL-SDR USB radio, you can design and prototype systems that process real-time wireless signals in MATLAB and Simulink.
