Abstract: A method and a device detect and reproduce radiotelephony messages emitted by a plurality of transmitters via radio at an air traffic controller workplace. It is analyzed whether a plurality of radiotelephony messages arriving at the air traffic controller workplace overlap one another chronologically, and if they do, one of the radiotelephony messages is prioritized and immediately emitted at the air traffic controller workplace. At least one other radiotelephony message is buffered, and the at least one buffered radiotelephony message is emitted at the air traffic controller workplace after the end of the prioritized radiotelephony message.

Abstract: A method performs radio communication between a controller and a transport user. A controller creates voice signals which are transmitted via a switching system to a transmitting antenna as a radio signal. The voice signals are received via a receiving antenna and are transmitted to the switching system. A squelch signal is created and indicates whether the signal applied to the receiving antenna contains voice messages. A component of the voice signal emitted by the controller and is received with a time delay, is removed from the received voice signal or is compensated for, and a corrected voice signal is determined. The corrected voice signal is transmitted to the controller, if the squelch signal is present, the signal which is emitted by the controller and does not reach the switching system with a time delay is superimposed on the corrected voice signal and the latter is transmitted to the controller.
