- G1C01Question 1FCC 97.313(c)(1)
What is the maximum transmitter power an amateur station may use on 10.140 MHz?
- A200 watts PEP output Correct
- B1000 watts PEP output
- C1500 watts PEP output
- D2000 watts PEP output
Why: 10.140 MHz is on 30 meters, limited to 200 W PEP output.
- G1C02Question 2FCC 97.313
What is the maximum transmitter power an amateur station may use on the 12-meter band?
- A50 watts PEP output
- B200 watts PEP output
- C1500 watts PEP output Correct
- DAn effective radiated power equivalent to 100 watts from a half-wave dipole
Why: 12 meters allows up to 1,500 W PEP output.
- G1C03Question 3FCC 97.303(h)(1)
What is the maximum bandwidth permitted by FCC rules for amateur radio stations transmitting on USB frequencies in the 60-meter band?
- A2.8 kHz Correct
- B5.6 kHz
- C1.8 kHz
- D3 kHz
Why: USB on 60 meters is limited to 2.8 kHz of bandwidth.
- G1C04Question 4FCC 97.303(i)
Which of the following is required by the FCC rules when operating in the 60-meter band?
- AIf you are using an antenna other than a dipole, you must keep a record of the gain of your antenna Correct
- BYou must keep a record of the date, time, frequency, power level, and stations worked
- CYou must keep a record of all third-party traffic
- DYou must keep a record of the manufacturer of your equipment and the antenna used
Why: On 60 meters, an antenna other than a dipole means keeping a record of its gain.
- G1C05Question 5FCC 97.313
What is the limit for transmitter power on the 28 MHz band for a General Class control operator?
- A100 watts PEP output
- B1000 watts PEP output
- C1500 watts PEP output Correct
- D2000 watts PEP output
Why: On 10 meters a General may run up to 1,500 W PEP output.
- G1C06Question 6FCC 97.313
What is the limit for transmitter power on the 1.8 MHz band?
- A200 watts PEP output
- B1000 watts PEP output
- C1200 watts PEP output
- D1500 watts PEP output Correct
Why: 160 meters (1.8 MHz) allows up to 1,500 W PEP output.
- G1C07Question 7FCC 97.309(a)(4)
What must be done before using a new digital protocol on the air?
- AType-certify equipment to FCC standards
- BObtain an experimental license from the FCC
- CPublicly document the technical characteristics of the protocol Correct
- DSubmit a rule-making proposal to the FCC describing the codes and methods of the technique
Why: A new digital protocol's technical characteristics must be publicly documented first.
- G1C11Question 8FCC 97.313
What measurement is specified by FCC rules that regulate maximum power?
- ARMS output from the transmitter
- BRMS input to the antenna
- CPEP input to the antenna
- DPEP output from the transmitter Correct
Why: FCC power limits are measured as PEP output from the transmitter.
