Free HAM Radio Extra Class Test FCC Rules and Regulations Questions and Answers — Questions and Answers
Question 1: Under what specific condition is an amateur station authorized to transmit messages encoded to obscure their meaning?
- During a declared national emergency.
- When transmitting control commands to a space station. (Correct answer)
- For communications supporting public safety officials.
- When using digital modes on frequencies above 450 MHz.
Correct answer: When transmitting control commands to a space station.
FCC Part 97.113(a)(4) generally prohibits amateur stations from transmitting messages encoded to obscure their meaning. However, a specific exception is made for telecommand of a space station, allowing for the protection of the satellite's control systems.
Question 2: A ham radio operator with an Extra Class license is operating from their vehicle in a different city but within the same call sign region. What is the correct way for them to identify their station?
- State their call sign followed by 'mobile' and their current grid square.
- Transmit their call sign followed by a '/M' and the name of the nearest city.
- Transmit their assigned call sign without any additional indicators. (Correct answer)
- Announce their call sign and the new Maidenhead locator every 5 minutes.
Correct answer: Transmit their assigned call sign without any additional indicators.
According to FCC Part 97.119, an amateur station must transmit its assigned call sign at the end of each communication and at least every 10 minutes during a communication. While adding an indicator like '/M' for mobile operation is a common practice, it is not a regulatory requirement when operating within the same call sign region. Simply using the assigned call sign is fully compliant.
Question 3: What is the maximum permissible transmitter power for an amateur station transmitting spread spectrum (SS) emissions?
- 1500 watts PEP
- 100 watts PEP
- 10 watts PEP (Correct answer)
- 1 watt PEP
Correct answer: 10 watts PEP
FCC rule §97.311(d) was updated, reducing the maximum power for spread spectrum emissions. The rule now states that the transmitter power for SS must not exceed 10 W PEP.
Question 4: A control operator at a remotely controlled station is NOT required to be at the control point under which of the following conditions?
- When the station is operating below 30 MHz.
- When the station is being used for a public service event.
- When the station is operating under automatic control. (Correct answer)
- During brief test transmissions not exceeding one minute.
Correct answer: When the station is operating under automatic control.
FCC Part 97.109(d) specifies that when a station is being automatically controlled, the control operator is not required to be at the control point. For local and remote control, the control operator must be at the control point.
Question 5: If an Extra Class licensee is the control operator for a station licensed to a General Class operator, and the station is operating on a frequency available only to Extra Class licensees, which of the following identification procedures is required?
- The station must identify with the General Class licensee's call sign, followed by the Extra Class operator's call sign. (Correct answer)
- Only the Extra Class operator's call sign must be used.
- Only the General Class station's call sign must be used.
- The station must transmit both call signs at the beginning of each communication.
Correct answer: The station must identify with the General Class licensee's call sign, followed by the Extra Class operator's call sign.
According to FCC §97.119(e), when the operator license class held by the control operator exceeds that of the station licensee, an indicator consisting of the call sign assigned to the control operator's station must be included after the station's call sign. This allows operation using the higher privileges of the control operator.
Question 6: Which of the following responsibilities is shared equally by the station licensee and the control operator when they are different individuals?
- Maintaining the station's financial records.
- Paying the electricity bill for the station.
- The proper operation of the station in accordance with FCC rules. (Correct answer)
- Designing and building the station's antennas.
Correct answer: The proper operation of the station in accordance with FCC rules.
FCC rule §97.103(a) explicitly states that when the control operator is a different amateur operator than the station licensee, both persons are equally responsible for the proper operation of the station.
