Ham Radio General Class Test FREE Ham Radio General Class MCQ Questions and Answers 2 — Questions and Answers
Question 1: What is the maximum transmitting power permitted on the 20-meter band for a General class licensee?
- 1500 watts PEP (Correct answer)
- 500 watts PEP
- 1000 watts PEP
- 200 watts PEP
Correct answer: 1500 watts PEP
General class licensees are permitted a maximum of 1500 watts PEP output on the 20-meter band.
Question 2: Which sideband is conventionally used for voice transmissions on frequencies below 10 MHz in the HF bands?
- Lower sideband (LSB) (Correct answer)
- Upper sideband (USB)
- Double sideband (DSB)
- Vestigial sideband (VSB)
Correct answer: Lower sideband (LSB)
By convention, lower sideband (LSB) is used for SSB voice transmissions on HF frequencies below 10 MHz.
Question 3: What does the term 'standing wave ratio' (SWR) indicate in an antenna system?
- The impedance match between the feed line and antenna (Correct answer)
- The gain of the antenna in dBi
- The resonant frequency of the antenna
- The bandwidth of the antenna
Correct answer: The impedance match between the feed line and antenna
SWR measures how well the antenna impedance is matched to the feed line, with 1:1 being a perfect match.
Question 4: What is the purpose of a repeater's CTCSS tone?
- To prevent the repeater from responding to unwanted signals (Correct answer)
- To increase the repeater's output power
- To encrypt voice transmissions
- To identify the repeater automatically
Correct answer: To prevent the repeater from responding to unwanted signals
CTCSS (Continuous Tone-Coded Squelch System) tones prevent a repeater from being activated by unintended signals or interference.
Question 5: Which of the following is a requirement when operating a station under automatic control?
- The station must comply with the FCC rules at all times (Correct answer)
- The operator must be physically present at the control point
- The station may only transmit on VHF and above
- Automatic control is only permitted for repeater stations
Correct answer: The station must comply with the FCC rules at all times
A station under automatic control must still comply with all applicable FCC rules even without a control operator present.
Question 6: What is the approximate length of a half-wave dipole antenna for the 40-meter band?
- 66 feet (Correct answer)
- 33 feet
- 132 feet
- 40 feet
Correct answer: 66 feet
A half-wave dipole for 40 meters is approximately 66 feet long, calculated as half the wavelength with a typical shortening factor.
