G2A10

Which of the following statements is true of VOX operation versus PTT operation?

  • A.The received signal is more natural sounding
  • B.It allows “hands free” operation (correct answer)
  • C.It occupies less bandwidth
  • D.It provides more power output

WhyVOX operation's main advantage over PTT is that it allows hands free operation. VOX (voice-operated switch) keys the transmitter automatically when it detects your voice, letting you operate without touching a push-to-talk button, answer B. It doesn't change how natural the received audio sounds, doesn't reduce bandwidth, and doesn't affect output power, those are unrelated to how the transmitter gets keyed.
