Which mode of voice communication is most commonly used on the HF amateur bands?
Which of the following is an advantage when using single sideband as compared to other analog voice modes on the HF amateur bands?
Less bandwidth used and greater power efficiency
Very high fidelity voice modulation
Ease of tuning on receive and immunity to impulse noise
Less subject to interference from atmospheric static crashes
Which of the following statements is true of the single sideband voice mode?
Only one sideband is transmitted; the other sideband and carrier are suppressed
Only one sideband and the carrier are transmitted; the other sideband is suppressed
SSB is the only voice mode that is authorized on the 20-meter, 15-meter, and 10-meter amateur bands

Say your call sign during a break between transmissions by the other stations
Say "QRZ" several times followed by your call sign
Say "Break Break Break" and wait for a response
Say "CQ" followed by the call sign of either station
Why do most amateur stations use lower sideband on the 160-meter, 75-meter and 40-meter bands?
Current amateur practice is to use lower sideband on these frequency bands
Lower sideband is more efficient than upper sideband at these frequencies
Lower sideband is the only sideband legal on these frequency bands
Because it is fully compatible with an AM detector
Which of the following statements is true of voice VOX operation versus PTT operation?
It allows "hands free" operation
The received signal is more natural sounding
It occupies less bandwidth
It provides more power output
What does the expression "CQ DX" usually indicate?
The caller is looking for any station outside their own country
A general call for any station
