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?
CFRB in Toronto.
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.
