What does PTT stand for in radio communication?

In radio communication, PTT stands for "Push To Talk." This term refers to a method used in two-way radio systems where the user presses a button to enable the microphone for transmission, allowing them to speak to others over the radio network. When the button is released, the transmission stops, enabling others to respond. This system is efficient for ensuring that only one party transmits at a time, reducing interference and clarifying communication.

The other terms provided do not accurately represent standard terminology in radio communication. Options such as "Private Transmit Time," "Public Talk Time," and "Passive Transmission Technology" do not correspond to widely recognized practices or methods used in radio operations. Hence, "Push To Talk" remains the correct and relevant term within the context of radio communication practices.
