Grig is a simple Ham Radio control (CAT) program based on the Ham 
Radio Control Libraries (Hamlib). It is intended to be highly 
generic presenting the user to the same graphical user interface 
regardless of which radio is being controlled.

Grig supports the most commonly used CAT commands that are implemented 
by Hamlib, and integrates well with other ham radio programs like Xlog 
and gMFSK. Thanks to Hamlib, grig works with most CAT-capable amateur 
radios. You can check out the Supported Radios page at the Hamlib website.
