So, you are interested in using an SDR module and SDR software on your Mac?
Homebrew is the easiest install method I have found. The other method involves MacPorts. I was successful using this method on one Mac. On the other… nope.
GQRX is a great open-source program that will do the trick.
First you will need homebrew (if you don’t already have it). It’s a great source for open-source software!
The first command may not work in your system. If not, proceed to the second one.
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Verify the install worked.
Then you will need to run the homebrew command in a terminal.
brew cask install gqrx
