Which of the following is an advantage of using single sideband, as compared to other analog voice modes on the HF amateur bands?
Very high-fidelity voice modulation
Less subject to interference from atmospheric static crashes
Ease of tuning on receive and immunity to impulse noise
Less bandwidth used and greater power efficiency✓Respuesta correcta
Explicación
Suppressing the carrier and one sideband removes two of the three parts of an AM signal, which roughly halves the occupied bandwidth and directs the whole transmitter output into the sideband that carries the voice. SSB is in fact harder to tune and no more immune to static than AM, so the fidelity, static and tuning claims are wrong.
