Sub Element G2: Operating Procedures Flashcards
Which sideband is most commonly used for voice communications on frequencies of 14 MHz or higher?
Upper sideband
Which of the following modes is most commonly used for voice communications on the 160-meter, 75-meter, and 40-meter bands?
Lower sideband
Which of the following is most commonly used for SSB voice communications in the VHF and UHF bands?
Upper sideband
Which mode is most commonly used for voice communications on the 17-meter and 12- meter bands?
Upper sideband
Which mode of voice communication is most commonly used on the HF amateur bands?
Single sideband
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
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
What is the recommended way to break in to a phone contact?
Say your call sign once
Why do most amateur stations use lower sideband on the 160-meter, 75-meter, and 40- meter bands?
It is good amateur practice
Which of the following statements is true of voice VOX operation versus PTT operation?
It allows “hands free” operation
Generally, who should respond to a station in the contiguous 48 states who calls “CQ DX”?
Any stations outside the lower 48 states
What control is typically adjusted for proper ALC setting on an amateur single sideband transceiver?
Transmit audio or microphone gain
Which of the following is true concerning access to frequencies in non-emergency situations?
Except during FCC-declared emergencies, no one has priority access to frequencies
What is the first thing you should do if you are communicating with another amateur station and hear a station in distress break in?
Acknowledge the station in distress and determine what assistance may be needed
What is good amateur practice if propagation changes during a contact and you notice interference from other stations on the frequency?
Attempt to resolve the interference problem with the other stations in a mutually acceptable manner
When selecting a CW transmitting frequency, what minimum separation should be used to minimize interference to stations on adjacent frequencies?
150 to 500 Hz
When selecting an SSB transmitting frequency, what minimum separation should be used to minimize interference to stations on adjacent frequencies?
Approximately 3 kHz
What is a practical way to avoid harmful interference on an apparently clear frequency before calling CQ on CW or phone?
Send “QRL?” on CW, followed by your call sign; or, if using phone, ask if the frequency is in use, followed by your call sign
Which of the following complies with good amateur practice when choosing a frequency on which to initiate a call?
Follow the voluntary band plan for the operating mode you intend to use
What is the voluntary band plan restriction for U.S. station transmitting within the 48 contiguous states in the 50.1 to 50.125 MHz band segment?
Only contacts with stations not within the 48 contiguous states
Who may be the control operator of an amateur station transmitting in RACES to assist relief operations during a disaster?
Only a person holding an FCC-issued amateur operator license
When is an amateur station allowed to use any means at its disposal to assist another station in distress?
At any time during an actual emergency
What frequency should be used to send a distress call?
Whichever frequency has the best chance of communicating the distress message
Which of the following describes full break-in telegraphy (QSK)?
Transmitting stations can receive between code characters and elements
