I appreciate all of your feedback - a couple of really helpful posts there. I was surprised at the amount on negative feedback - let me please clarify things. I'm not some nutcase who won't be happy unless pumping the Top Gun theme music through his headset while in the heathrow control zone. I simply would like to hook up a CD player on low volume for brief moments with no radio contact. As someone commented, we're all responsible adults so please don't worry about me!
