How did the term "Roger Wilco, Over and Out" get started? Is this just a term
from the old sci-fi and war "B" movies?


Bill N8KDV pointed out the meaning of the term WILCO. The term ROGER
(taken from previous phonetic alphabets and as mentioned prior to that
from morse and indeed semaphore) is used to signify that you've received
the message correctly, nothing more. The 2 terms OVER and OUT, almost
always misused in any movie, are 2 individual terms with different
meanings...OVER signifies to the station just finishing transmitting
that it is expecting a reply...OUT signifies that the station finishing
transmitting is finished but not expecting any further reply. Any real
radio operator/officer knows better than to say OVER and OUT. These are
of course voice procedure terms, standardized over decades of trial and
error to have a consistent sound in many languages as are the ITU
phonetic alphabet in worldwide use (except by some U.S. law enforcement
agencies I'm led to believe).
