PTT - Push To Talk

PTT, Push To Talk, is the key used to enable the transmission of the radio signal in half-duplex transceivers.

In half-duplex transceivers it represents the key to be pressed to enable the transmission of your own communication and which must be released in order to be able to listen to the voice of the other party.

It is essential to release the PTT key as soon as our communication has been sent, otherwise we will not be able to receive the communication of the interlocutor.
