Every now and then there is an ad where the seller uses the term NIB or 'new in the box' to describe a radio that has obviously been used. For example, there is a current ad running for a 746 Pro and his picture shows it is up and running. Besides, 746 Pro radios have not been NIB for a long, long time. I thought NIB meant exactly that. New, never been hooked up or used, never out of the box. Thoughts and comments?
