What happens when the PTT button is pressed?

• A. Radio switches to standby
• B. Radio will continuously transmit RF over the air while the button is pressed
• C. Radio changes frequency
• D. Radio encrypts the signal

Answer: (B)

The Push-To-Ttalk control is the transmit switch. When you press it, the radio switches from receive to transmit, feeding your voice into the transmitter so the carrier is sent out on the current channel. As long as you hold the button, the transmitter stays on and your audio modulates the RF signal, so you’re continuously transmitting over the air for the duration of the press. When you release, the transmitter turns off and you return to receive or standby. That’s why this option is the best fit: the PTT button directly initiates transmission on the current frequency, not switching frequencies or encrypting the signal, and it doesn’t leave you in standby while you’re actively talking.
