Which of the following is true concerning access to frequencies?
- Nets always have priority
- QSOs in progress always have priority
- Except during emergencies, no amateur station has priority access to any frequency
- Contest operations must always yield to non-contest use of 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?
- Continue your communication because you were on the frequency first
- Acknowledge the station in distress and determine what assistance may be needed
- Change to a different frequency
- Immediately cease all transmissions
What is good amateur practice if propagation changes during a contact and you notice interference from other stations on the frequency?
- Tell the interfering stations to change frequency
- Report the interference to your local Amateur Auxiliary Coordinator
- Attempt to resolve the interference problem with the other stations in a mutually acceptable manner
- Increase power to overcome interference
When selecting a CW transmitting frequency, what minimum separation should be used to minimize interference to stations on adjacent frequencies?
- 5 to 50 Hz
- 150 to 500 Hz
- 1 to 3 kHz
- 3 to 6 kHz
When selecting an SSB transmitting frequency, what minimum separation should be used to minimize interference to stations on adjacent frequencies?
- 5 to 50 Hz
- 150 to 500 Hz
- Approximately 3 kHz
- Approximately 6 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
- Listen for 2 minutes before calling CQ
- Send the letter "V" in Morse code several times and listen for a response, or say "test" several times and listen for a response
- Send "QSY" on CW or if using phone, announce "the frequency is in use," then give your call sign and listen for a response
Which of the following complies with good amateur practice when choosing a frequency on which to initiate a call?
- Check to see if the channel is assigned to another station
- Identify your station by transmitting your call sign at least 3 times
- Follow the voluntary band plan for the operating mode you intend to use
- All these choices are correct
What is the voluntary band plan restriction for U.S. stations 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
- Only contacts with other stations within the 48 contiguous states
- Only digital contacts
- Only SSTV contacts
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
- Only a RACES net control operator
- A person holding an FCC-issued amateur operator license or an appropriate government official
- Any control operator when normal communication systems are operational
When is an amateur station allowed to use any means at its disposal to assist another station in distress?
- Only when transmitting in RACES
- At any time when transmitting in an organized net
- At any time during an actual emergency
- Only on authorized HF frequencies
What frequency should be used to send a distress call?
- Whichever frequency has the best chance of communicating the distress message
- Only frequencies authorized for RACES or ARES stations
- Only frequencies that are within your operating privileges
- Only frequencies used by police, fire, or emergency medical services
