What is the function of the PTT button on a two-way radio?

• A. Enable duplex transmission
• B. Cause the radio to transmit
• C. Transmit a distress signal
• D. Adjust the sensitivity of signal reception

Answer: (B)

The Push-To-Talk button is the manual control that turns on your radio’s transmitter. When you press and hold it, your voice is transmitted on the selected channel so everyone listening on that channel can hear you. Releasing the button stops transmission and the radio returns to receive mode so you can hear replies. This is how you initiate conversations on the radio. It isn’t about duplexing, distress signaling, or adjusting receiver sensitivity. You use it to speak, and release to listen.
