Gnome RIG is a graphical user interface to the Ham Radio Control Libraries, which lets you control your communication radios and/or antenna rotators from a personal computer. Gnome RIG is written using the Gtk+ and Gnome widgets. . Gnome RIG is in a very early stage and it supports only a very little subset of the full Hamlib API, but it can be very useful in testing basic hamlib support for your rig.
