License Exam Quiz #276
de Steve, AE8AT

With our celebration of the new Extra question pool coming to a close, we will enter a long period without a refresh, the next being the Technician pool which renews in 2026. Instead we must turn to other sources for the inspiration for the quiz. Today, as I was leaving campus, a man was struggling greatly with the complexity of reverse, and without any other vehicle around him (thankfully). It is to this gentleman, dropping his young son off for some activity, that served as inspiration. Our topic today is reverse!

 

T2B01 How is a VHF/UHF transceiver’s “reverse” function used?
A. To reduce power output
B. To increase power output
C. To listen on a repeater’s input frequency
D. To listen on a repeater’s output frequency

 

G4A02 What is the benefit of using the opposite or “reverse” sideband when receiving CW?
A. Interference from impulse noise will be eliminated
B. More stations can be accommodated within a given signal passband
C. It may be possible to reduce or eliminate interference from other signals
D. Accidental out-of-band operation can be prevented

 

E6A03 Why does a PN-junction diode not conduct current when reverse biased?
A. Only P-type semiconductor material can conduct current
B. Only N-type semiconductor material can conduct current
C. Holes in P-type material and electrons in the N-type material are separated by the applied voltage, widening the depletion region
D. Excess holes in P-type material combine with the electrons in N-type material, converting the entire diode into an insulator

 

Answers:
T2B01 = C
G4A02 = C
E6A03 = C
