Roger Beep tones have been used to signal more clearly the end of a transmission with SSB transmitters.
The Roger Beep tone in is a short tone burst (a beep or -K- or -T-) that is transmitted when the user releases the PTT button.

In the QRM, Noise, QSB clear message of transmission/receipt - take over switching.
Better identification of the station
in QRM, noise, QSB, ....
