LIVE QUESTIONS FOR SEPTEMBER 5 & 6 - 2026, SUPPLIED BY K2HA
1. RG (as in RG-213, RG-11, RG-8 coax) stands for:
A: RF Guide
B: Radio Guide
C: Radio Ground
D: Reactance Grade
2. Until 1925, radios relied on messy storage batteries. Who invented the first alternating-current radio tube that allowed radios to run on household electricity?
A: Hiram Percy Maxim
B: John Ambrose Fleming
C: Edwin Howard Armstrong
D: Edward S. "Ted" Rogers Sr
Extra credit question: What commercial broadcast station did this inventor start and where was it located?
3. In high-frequency (HF) skywave propagation, what primary mechanism sustains long-distance communication when a refracted wave returns to the Earth's surface?
A: Specular reflection off the tropospheric boundary layer.
B: Ground reflection that redirects the signal back into the ionosphere for a subsequent hop.
C: Induced surface plasmon resonance along the oceanic dielectric interface.
D: Ground-wave diffraction along the geoid curvature to compensate for line-of-sight loss.
4. Why do electronic engineers caution against using USB flash drives for long-term data storage and archiving?
A: Floating-gate electrons gradually tunnel out of the dielectric layer, leading to charge leakage.
B: The internal charge pumps require continuous VCC to prevent immediate volatile erasure.
C: Minor exposure to ambient HF/VHF stray RF fields routinely causes catastrophic gate oxide dielectric breakdown.
D: The wear-leveling algorithms require periodic read-refresh cycles to maintain magnetic domain alignment.
THE ANSWERS TO THE ABOVE QUESTIONS WILL BE POSTED HERE SHORTLY AFTER THE CONCLUSION OF THE SUNDAY RAGCHEW NET
LIVE QUESTIONS FOR AUGUST 29 & 30 - 2026, SUPPLIED BY K2HA
1. Which of these digital ham platforms is presently not included on QSO One (qso1.net)?
A: D-STAR
B: Fusion
C: Allstar
D: DMR
2. What is the Sheffer stroke that Henry Maurice Sheffer identified in 1913?
A: A rare calligraphy style known for its sharp, vertical downward ink strokes.
B: A logical operator in propositional logic and Boolean algebra that corresponds to “NAND”.
C: A foundational rowing stroke introduced at the 1924 Olympics to maximize water displacement.
D: A medical term for a minor, localized stroke that only affects a patient's short-term motor memory.
3. What logical operation does a NAND gate perform?
A: It produces a 0 at its output only if all inputs are 0.
B: It produces a 0 at its output only if all inputs are 1.
C: It produces a 0 at its output if some but not all inputs are 1.
D: It produces a 1 at its output only if all inputs are 1.
4. When using hydrophobic coatings on your coax connectors and antennas, what result would you not expect?
A: To increase the radiated power.
B: Reduced metal joint oxidization.
C: No freezing of system parts.
D: Water resistance.
