Gqrx is a software defined radio receiver powered by the GNU Radio SDR framework and the Qt graphical toolkit. It supports many of. It supports many of. Free Open Source Mac Linux. Mac OSX users can have a hard time with the RTL-SDR as there are not many software packages available for it. One software package that is known to work well on OSX is GQRX, which is a general multi mode receiver GUI that is similar to the Windows software SDR#. Gqrx binary package for Mac OS X, experimental build and known to have problems. Built on Mac OS X 10.11 but might work up to 10.15 (SourceForge) On Mac you can also install the latest version through Macports and probably also other package managers like Homebrew. I can only provide very limited support for Mac OS X.

This video explains how the RTL-SDR dongle works. I will show you how to open the RTL-SDR dongle and show you (very detailed) what it inside this particular dongle and the included antenna. This particular RTL-SDR dongle is nameless but has the following chipsets: – The radio tuner: Rafael Micro R820T2 – The demodulator: RealTek RTL2832U The dongle has a female mcx (micro coax) port to connect the antenna. The antenna has a male mcx plug. This video also shows you how to install the SDR program GQRX on a Mac OS X (macOS Sierra) and how to use the GQRX program. Download the GQRX SDR program from: http://gqrx.dk/ The RTL-SDR dongle can be purchased at: https://www.aliexpress.com/item/USB2-0-DAB-FM-DVB-T-RTL2832-R820T-SDR-RTL-SDR-Dongle-Stick-Digital-TV-Tuner/32267130430.html Subscribe
