Its amazing how only the UK requires you to have an RT licence isn't it? For the cyncical amongst us it would be easy to assume its a money making means for the CAA. I can't think of to many aircraft that fall out of the sky because some US, Oz, kiwi etc pilot doesn't hold a special piece of paper saying that they were able to sit in a booth for 10 minutes talking to a bloke 2 feet away on a make believe flight.
