Fedora already includes tvtime, which is an outstanding TV viewer application. It would be nice if it would include a comparable radio application.
I've been using GQradio since RH9, it's working very well, it has a good feature set:

Here are RPMs made by myself for FC2:

yes, since we dropped xawtv which had "radio", I am missing a radio app, too. I'll have a look at GQradio.
