In Game Radio

A few questions I was not able to get an answer by myself.

I was looking in MXO Resource and I noticed the commands including the /radio and so forth but they do not seem to work so... here some questions:

• 1) Is the radio on 24/7 or only during a specific time schedule?
• 2) Are there many radio to chose from and how?
• 3) How do I make it work? I would need a step-by-step guide if at all possible.

Thanks,
