Oh dear me! This is SO far OT that I would trash my own post if i was a Mod, but that is wrong and conflicting terminology perpetuated by American cop shows. In correct radio-telephone voice procedure, civil & military etc, these are the meanings of those common prowords:

'Roger' means "I have received your last transmission satisfactorily (and understood it)" (So far so good, we know it was really just a pun by drammer on the nick of roger1109)

'Over' means "This is the end of my transmission to you and a response or answer is necessary"
'Out' means "This is the end of my transmission to you and no response or answer is required or expected"

Ergo: 'Over' and 'Out' used together is a nonsense.

Sorry Caty/ddabcd277 et al, got it out of my system now... trash away.
