Push to Talk (PTT) is used to which action?

Push to Talk (PTT) is used to which action?

• A. Switches between receive and transmit.
• B. Increase the squelch level.
• C. Toggle encryption.
• D. Change the antenna.

Answer: (A)

Push to Talk is the control you press to begin transmitting on the radio. When you depress it, the radio switches from receiving to transmitting, allowing your microphone audio to be sent over the channel. Releasing returns the radio to receive so you can hear responses. This behavior is why PTT is used to switch between receive and transmit. Squelch, encryption, and antenna changes are handled by different controls or settings, not by the push-to-talk action.
