This is a radio amateur (HAM) digital mode program for use with a radio transceiver, to communicate with others
It is also meant for researching weak signal propagation, it includes the very popular FT8 and WSPR modes

This is the download page (same page) (tar.gz source is there with version numbers): https://www.physics.princeton.edu/pulsar/k1jt/wsjtx.html
There is no similar package in Solus at the moment, I like Solus and would like this "wsjtx" to be included :-)
Radio amateurs like to use this program, it is Open Source, and may be distributed, WSJT-X is licensed under the terms of Version 3 of the GNU General Public License (GPL) (as it says on the homepage) and in the file COPYING in the tarball
