SARL Radio Amateur Examination Class A (HAREC) Flashcards and Exam Questions
Question
A station measures a forward power of 100 watts and a reflected power of 10 watts. What operational condition does this indicate?
Answer and Explanation
This indicates an impedance mismatch between the transmitter and the antenna system, resulting in a Standing Wave Ratio (SWR) greater than 1:1. In a perfectly matched system, all forward power is radiated, and reflected power is zero. This aligns with the official syllabus section on Antennas, Feedlines, and SWR measurement, demonstrating the practical need to monitor and minimize reflected power to protect the transmitter.
Question
According to ICASA regulations, what is the minimum passing requirement to earn the Class A HAREC certification?
Answer and Explanation
The correct requirement is an overall average of 65%, with a mandatory sub-minimum of 50% in the Regulations section and 50% in the Technical Theory section. A common misconception is that a simple 65% total is sufficient, but a candidate who scores 90% in theory and 40% in regulations will fail. This directly addresses the strict assessment criteria set by the official administrator.
Question
What is the primary purpose of a superheterodyne receiver's intermediate frequency (IF) stage?
Answer and Explanation
The primary purpose is to convert varying incoming RF signals to a constant, fixed intermediate frequency, allowing for consistent and highly selective filtering and amplification. Distractors often incorrectly suggest the IF stage handles demodulation or power amplification. Understanding frequency translation to a fixed IF is a core objective in the Receivers and Transmitters module of the content outline.
Question
During peak sunspot activity (Solar Maximum), which propagation phenomenon is most likely to occur on the higher HF bands, such as 10 meters?
Answer and Explanation
Increased ionization of the F-layers allows the higher HF bands to support long-distance, intercontinental skywave communication. During solar minimums, these bands often "close" and do not reflect skywaves reliably. Understanding the correlation between the 11-year solar cycle, ionospheric density, and frequency selection is a heavily tested concept within the Radio Wave Propagation syllabus.
Comprehensive SARL Radio Amateur Examination Class A (HAREC) Study Guide
Basics | Format | Registration | Results | Study Tips
What is the exam?
The Radio Amateur Examination (RAE) Class A is the comprehensive written assessment required to obtain an unrestricted amateur radio license in South Africa. Passing the exam grants a Harmonised Amateur Radio Examination Certificate (HAREC), verifying that the candidate has mastered foundational electronics, radio propagation, and legal operating parameters.
Who administers it?
The exam is administered by the South African Radio League (SARL) on behalf of the Independent Communications Authority of South Africa (ICASA), which is the nation's official communications regulator.
Why should someone take it?
Candidates take the Class A exam to legally transmit on designated amateur radio frequency bands with maximum allowed power. It is essential for enthusiasts who wish to communicate globally, experiment with advanced electronics, or participate in emergency communication networks without the power and frequency limitations imposed on entry-level Class B licensees.

Crucial Study Advisory: Candidates frequently struggle with the mathematics behind AC Circuits and Tuned Filters, particularly calculating resonance and phase angles. This is difficult because it moves beyond simple multiplication into abstract concepts of reactance. To overcome this: 1) Memorize the foundational formulas early, 2) Practice converting values (like microfarads and millihenries) correctly before calculating, and 3) Draw circuit diagrams for every practice problem to visualize the signal flow.
Score Calculator
Because the official examination consists of a single paper with an undisclosed total number of questions, there is no public raw-to-scaled conversion formula. However, the scoring method strictly enforces sub-minimums. Below is an illustrative example of how a pass/fail determination is calculated.
Section | Illustrative Score | Sub-Minimum Requirement | Status |
Regulations | 60% | 50% | Pass |
Technical Theory | 70% | 50% | Pass |
Overall Average | 65% | 65% | PASS |
To turn your practice test results into a targeted study plan, categorize every missed question by syllabus topic. If your practice scores frequently dip below 55% in the Regulations section, you must pause technical studying and focus heavily on legal frameworks, as failing that section will cause an automatic failure of the entire exam, regardless of your overall average.
