A reader, Mick Walker, wrote in to inform me that Linux users might have trouble accessing CAD Radio with the above methods, and offers a solution:
Just to let you know, that some of your Linux readers may have trouble listening to the online radio stream.
I dont know if you wish to inform them on the website, but here is a simple work around.
1. Download mplayer (binary or source) from http://www.mplayerhq.hu
2. Install it.
3. From a terminal or the command line simply run
$ mplayer http://1plonewolf.qc1.net:8010/
Thanks Mick!
