Ham Radio Technician Test Amateur 2 — Questions and Answers
Question 1: Which agency issues amateur radio licenses in the United States?
- The FCC (Federal Communications Commission) (Correct answer)
- The ITU (International Telecommunication Union)
- ARRL (American Radio Relay League)
- The Department of Commerce
Correct answer: The FCC (Federal Communications Commission)
The FCC is the U.S. government agency responsible for regulating and licensing amateur radio operators.
Question 2: What is the term for the region of the ionosphere used most by amateur radio operators for long-distance HF communication?
- D layer
- E layer
- F layer (Correct answer)
- G layer
Correct answer: F layer
The F layer of the ionosphere is the primary layer responsible for long-distance HF skywave propagation.
Question 3: What does it mean when a repeater is described as having a 'positive offset'?
- The repeater transmits on a higher frequency than it receives (Correct answer)
- The repeater transmits on a lower frequency than it receives
- The repeater operates above 100 watts
- The repeater requires a CTCSS tone above 100 Hz
Correct answer: The repeater transmits on a higher frequency than it receives
A positive offset means the repeater's transmit frequency is higher than its receive frequency.
Question 4: Which of the following is a characteristic of a dipole antenna?
- It requires a ground plane to operate
- It is omnidirectional in the plane perpendicular to its length (Correct answer)
- It only works on a single frequency
- It must be oriented vertically
Correct answer: It is omnidirectional in the plane perpendicular to its length
A dipole antenna radiates in a donut-shaped pattern that is omnidirectional in the plane perpendicular to its axis.
Question 5: What is the maximum power an amateur station may use on the 70 cm band if it causes interference to a government radar station?
- 50 watts
- 5 watts
- The FCC may impose power limits on a case-by-case basis (Correct answer)
- No power limit applies
Correct answer: The FCC may impose power limits on a case-by-case basis
The FCC can impose site-specific power limits on amateurs operating near government radar stations in the 70 cm band.
Question 6: What type of modulation does a standard FM voice repeater use?
- AM (amplitude modulation)
- SSB (single sideband)
- FM (frequency modulation) (Correct answer)
- CW (continuous wave)
Correct answer: FM (frequency modulation)
FM (frequency modulation) is the standard modulation used for voice communications on VHF/UHF repeaters.
Question 7: What is 'third-party traffic' in amateur radio?
- Messages sent between two foreign amateur stations
- Communications on behalf of a person who is not a licensed amateur (Correct answer)
- Traffic relayed through a third repeater
- Any message transmitted via packet radio
Correct answer: Communications on behalf of a person who is not a licensed amateur
Third-party traffic refers to amateur radio messages handled on behalf of a non-licensed person (the third party).
