The band Rogerthat is pretty good, but this vanity plate is most certainly the military confirmation statement. So, what is the origin of “Roger” as confirmation or affirmative?
ROGER — “in the meaning of ‘Yes, O.K., I understand you — is voice code for the letter R. It is part of the ‘Able, Baker, Charlie’ code known and used by all radiophone operators in the services. From the earliest days of wireless communication, the Morse code letter R (dit-dah-dit) has been used to indicate ‘O.K. — understood.’ So ‘Roger’ was the logical voice-phone equivalent.”
