G2A01:
Which sideband is most commonly used for phone communications on the bands above 20 meters?
Upper Sideband
Lower Sideband
Vestigial Sideband
Double Sideband
G2A02:
Which sideband is commonly used on the 160, 75, and 40 meter bands?
Lower Sideband
Upper Sideband
Vestigial Sideband
Double Sideband
G2A03:
Which sideband is commonly used in the VHF and UHF bands?
Upper Sideband
Lower Sideband
Vestigial Sideband
Double Sideband
G2A04:
Which mode is most commonly used for voice communications on the 17 and 12 meter bands?
Upper Sideband
Lower Sideband
Vestigial Sideband
Double Sideband
G2A05:
Which mode of voice communication is most commonly used on the High Frequency Amateur bands?
SSB
FM
AM
PM
G2A06:
Which of the following is an advantage when using single sideband as compared to other voice modes on the HF amateur bands?
Less bandwidth used and high power efficiency
Very high fidelity voice modulation
Ease of tuning on receive
Less subject to static crashes (atmospherics)
G2A07:
Which of the following statements is true of the single sideband (SSB) 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 voice transmissions have higher average power than any other mode
SSB is the only mode that is authorized on the 160, 75 and 40 meter amateur bands
G2A08:
Which of the following statements is true of single sideband (SSB) voice mode?
It is a form of amplitude modulation in which one sideband and the carrier are suppressed
It is a form of frequency modulation in which higher frequencies are emphasized
It reproduces upper frequencies more efficiently than lower frequencies
It is the only voice mode authorized on the HF bands between 14 and 30 MHz
G2A09:
Why do most amateur stations use lower sideband on the 160, 75 and 40 meter bands?
Current amateur practice is to use lower sideband on these frequency bands
The lower sideband is more efficient at these frequency bands
The lower sideband is the only sideband legal on these frequency bands
Because it is fully compatible with an AM detector
G2A10:
Which of the following statements is true of VOX operation?
VOX allows "hands free" operation
The received signal is more natural sounding
Frequency spectrum is conserved
The duty cycle of the transmitter is reduced
G2A11:
Which of the following user adjustable controls are usually associated with VOX circuitry?
All of these choices are correct
Anti-VOX
VOX Delay
VOX Sensitivity
G2A12:
What is the recommended way to break into a conversation when using phone?
Say your call sign during a break between transmissions from 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
G2A13:
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
The caller is listening for a station in Germany
This is a form of distress call
