The GQRX is an open source software defined radio which uses GNU Radio. It works on Linux and aswell on Mac OS X.
well it's really easy if you have Homebrew installed. If you don't have Homebrew install it from: https://brew.sh/
- GQRX Homepage: https://gqrx.dk/
- GQRX GitHub: https://github.com/csete/gqrx/
Install it with Brew
then you just have to install GQRX for Mac OS X with:
brew cask install gqrx
The first time you open the software you have to right-click it on the Icon in the application folder to open it up. Be sure to select the right adapter in the drop down menu:
After that it all works:
If you don't have Brew and want to compile it yourself
git clone https://github.com/csete/gqrx.git cd gqrx mkdir build cd build cmake .. make
git clone https://github.com/csete/gqrx.git && cd gqrx && mkdir build && cd build && cmake .. && make
I had no antenna installed and my SDR is really old :) have to get a better one. If you have an suggestion what radio to use, please write in the comments below. I had problems with mine all along. I get so much noise from my computer. I guess its from the computer hardware and I cant get rid of it. I used the USB-Isolator Module:
This one: https://s.click.aliexpress.com/e/_dWfBy1N (Affliate Link) I had it lying around in my electronic boxes ;) must have ordererd it sometimes.
It's an USB Port isolator. It isolates not like an opto-coupler but with coils like an transformer. It's really cool:
The ADuM4160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers. Data direction is determined on a packet-by-packet basis.
You supply it with an Power Pack or other external power and it isolates everything, including ground. But sadly it won't work with the RTL-SDR. Otherwise it's an really cool thing :) I have tested it with an ESP8266 and the Serial over USB connection works just finde.
