What is it?
cRadio is a QT - X11 interface that can control a radio card connected to your pc.

cRadio started as a result of me wanting to learn X-windows programming and due to the fact that there were no decent looking radio card programs for linux out there. I took a brief look at the various tool kits out there, and decided on using qt as it was the simplist and quickest toolkit to use. I want to one day try to re-write cRadio using qtk, but firstly I'll be devoted to improving and finishing off this version.
