LIVE QUESTIONS FOR AUGUST 8 & 9 - 2026, SUPPLIED BY K2HA
NB: This week’s questions are based on a British Ham Radio Intermediate Mock Exam!
1. What is the total resistance of a parallel combination of 1.8 kΩ, 2.7 kΩ, and 3.3 kΩ resistors?
A: 2.6kΩ
B: 814Ω
C: 7.8kΩ
D: 2.7kΩ
2. Which ONE of the statements below about an inductor is true?
A: It blocks direct current but allows alternating current to flow.
B: It consists of two metal plates separated by an insulating material.
C: It is able to store an electric charge.
D: It is typically a coil of wire with multiple turns.
3. Rechargeable batteries are often marked with a capacity value in ampere-hours. What does this value represent?
A: Total electric charge a battery can deliver on full discharge.
B: The time after which the battery should be recharged.
C: The time for which the battery will power the connected device.
D: The maximum charging current at which the battery can be safely charged.
4. Which of the following statements regarding the D layer of the ionosphere is correct?
A: The layer disappears after sunset.
B: The layer absorbs some HF radio signals during the day.
C: The layer reflects some HF radio signals at night.
D: The layer is so weak that it has little effect on HF radio signals at any time.
THE ANSWERS TO THE ABOVE QUESTIONS WILL BE POSTED HERE SHORTLY AFTER THE CONCLUSION OF THE SUNDAY RAGCHEW NET
LIVE QUESTIONS FOR AUGUST 1 & 2 - 2026, SUPPLIED BY K2HA
1, A Ham in New York sent an old 240-volt linear Kilowatt amplifier to a Ham in Switzerland. When it was used, the power transformer failed. Which is the most likely problem?
A: Wrong line frequency.
B: The SWR was too high.
C: It was hooked up wrong.
D: It was damaged in transport.
2, What is the maximum power you can safely transmit through high-quality outdoor 75-ohm RG6 television coaxial cable on the 70-centimeter band considering the impedance mismatch at the transmitter?
A: 30 watts
B: 50 watts
C: 100 watts
D: 200 watts
3, Which answer is NOT the reason TV coax uses 75-ohm and not 50-ohm coax like amateur radio?
A: 75-ohm coax is optimized for minimum signal attenuation/loss over long distances.
B: High power signals are not usually used in 75-ohm home television installations.
C: An impedance of roughly 77 ohms mathematically offers the absolute lowest signal loss (attenuation) for delicate voltage signals.
D: Cable companies found that 75-ohm coax was cheaper to construct than 50-ohm coax.
4, Which answer does NOT describe a reasonable cause of amateur radio signal flutter?
A: Radio waves traveling via multiple paths arrive at your antenna slightly out of phase.
B: High-frequency (HF) signals refract through a constantly moving, turbulent ionosphere.
C: The movement of your antenna blowing in the wind causes flutter.
D: Signals reflect or pass through ionized particles in aurora (northern/southern lights) activity.
