First I tried to compile it from the source at the official SVN repo, but I ran into difficulties.
The easiest way to go is to add the following PPA to
deb http://ppa.launchpad.net/ki7mt/wspr/ubuntu trusty main deb-src http://ppa.launchpad.net/ki7mt/wspr/ubuntu trusty main
The next step is to install
sudo apt-get update sudo apt-get install wspr
wspr by typing:
Select the pulse audio input device at Setup / Station parameters.
On the main screen don’t forget to uncheck the Idle button, until that the software will not do anything.
