ARRL Amateur Radio Technician License Examination — Questions and Answers

Question 1: What does the Q-code 'QRM' indicate?

Equipment malfunction
Man-made interference (Correct answer)
Natural atmospheric static
Signal fading due to propagation

Correct answer: Man-made interference

QRM refers to man-made interference from other radio transmitters, distinguishing it from QRN which is natural noise.

Question 2: What is the primary purpose of a 'resolution' section in a narrative about overcoming interference on a contest weekend?

To recommend new FCC regulations
To list all contacts made during the interference
To blame the source of the interference
To show how the problem was solved and what was learned (Correct answer)

Correct answer: To show how the problem was solved and what was learned

The resolution section closes the narrative arc by demonstrating the outcome and any lessons learned, giving the story satisfying closure.

Question 3: What is the primary risk of using emotional appeals (pathos) without logical support in a persuasive argument?

Emotional appeals are always more effective than logical ones
Using pathos is considered unethical in all persuasive writing contexts
Readers may enjoy the writing too much and ignore the call to action
Skeptical readers may dismiss the argument as manipulative or unsubstantiated (Correct answer)

Correct answer: Skeptical readers may dismiss the argument as manipulative or unsubstantiated

Pathos without logos leaves the argument vulnerable to audiences who demand evidence, making the entire piece seem emotionally manipulative rather than genuinely reasoned.

Question 4: What is the 'gray line' and why is it significant for amateur radio operators?

A line on a map showing skip zone boundaries
The terminator between day and night where enhanced propagation often occurs (Correct answer)
A term for static-heavy band conditions during thunderstorms
The boundary between the E and F layers of the ionosphere

Correct answer: The terminator between day and night where enhanced propagation often occurs

The gray line is the twilight zone between day and night on Earth's surface; at this boundary, the D layer (which absorbs HF signals) is absent while the F layer remains ionized, creating excellent DX propagation conditions.

Question 5: What does the Q-code 'QSL' mean in an amateur radio exchange?

I acknowledge receipt of your transmission (Correct answer)
Please slow down your sending
What is your signal strength?
Are you ready to receive traffic?

Correct answer: I acknowledge receipt of your transmission

QSL means 'I confirm receipt' and is widely used both on-air and as the name for the paper confirmation cards operators exchange.

Question 6: What does ARES stand for in the ARRL community?

Automated Radio Emergency Signaling
Amateur Radio Enforcement Standards
Amateur Radio Emergency Service (Correct answer)

Correct answer: Amateur Radio Emergency Service

ARES (Amateur Radio Emergency Service) is an ARRL program that trains and organizes licensed amateurs to provide communications during emergencies.

Question 7: The K-index is a measure used in amateur radio propagation forecasting. What does a high K-index (K=5 or above) indicate?

Favorable sporadic-E conditions on VHF bands
Excellent HF propagation conditions with low absorption
Increased geomagnetic storm activity likely disrupting HF propagation (Correct answer)
High solar flux improving F2-layer ionization

Correct answer: Increased geomagnetic storm activity likely disrupting HF propagation

A K-index of 5 or above indicates a geomagnetic storm, which disturbs the ionosphere and typically degrades or disrupts HF propagation, especially at higher latitudes.

Question 8: What is the primary cause of ionization in the ionosphere that makes HF propagation possible?

Ultraviolet and X-ray radiation from the Sun (Correct answer)
Lightning strikes in the upper atmosphere
Geomagnetic storms from solar wind
Cosmic radiation from distant galaxies

Correct answer: Ultraviolet and X-ray radiation from the Sun

The Sun's ultraviolet and X-ray radiation ionizes gas molecules in the upper atmosphere, creating the ionosphere layers that refract HF radio waves.

Question 9: In ARRL contest rules, the term 'dupe' refers to what situation?

A contact verified by two independent log checkers
A contact made with an operator running two radios simultaneously
A repeated contact with the same station on the same band and mode, which does not count for credit (Correct answer)
Operating in two contest categories at once

Correct answer: A repeated contact with the same station on the same band and mode, which does not count for credit

A dupe (duplicate) is a contact with a station already worked on the same band and mode; most contest rules prohibit claiming credit for dupes.

Question 10: What does the Solar Flux Index (SFI) measure, and what value indicates good HF propagation conditions?

The number of sunspots visible; values above 50 indicate good conditions
Solar wind speed in km/s; values below 400 indicate stable propagation
The Sun's radio emission at 10.7 cm wavelength; values above 150 indicate enhanced propagation (Correct answer)
Geomagnetic storm intensity; values below 5 indicate good conditions

Correct answer: The Sun's radio emission at 10.7 cm wavelength; values above 150 indicate enhanced propagation

The Solar Flux Index measures the Sun's radio emission at 10.7 cm (2800 MHz); higher values (above 150 and especially above 200) indicate increased solar activity and better ionization of the F2 layer for HF propagation.

Question 11: When evaluating an online article about amateur radio regulations, which domain extension is most likely to indicate an authoritative US government source?
