1) ROGER BEEP

(s or UP)
The Roger Beep sounds when the PTT switch (11) on the microphone is
released in order to let your correspondent speak. Historically as trans-
ceiver is a "simplex" communication mode, it is not possible to speak
and to listen at the same time (as it is the case with a telephone). Once
someone had finished talking, he said "Roger" in order to prevent his
correspondent that it was his turn to talk. The word "Roger" has been
replaced by a significant beep. There comes "Roger beep" from.
