What is the function of a transceiver's PTT input?
Pick an answer to check it.
Answer: B. Switches transceiver from receive to transmit when grounded
PTT means push-to-talk. When the PTT input is grounded, such as by pressing the microphone button, the transceiver switches from receive to transmit. A CW key usually plugs into a separate key jack.
Tip: Push to talk: ground the PTT line to transmit.
