LIVE QUESTIONS FOR  FEB 14 & 15, 2026

SUPPLIED BY K2HA

1, The ratio between the input signal that can just be heard on a receiver and the signal level at which it overloads is known as the receivers:

A. noise factor

B. overload margin

C. receive threshold

D. dynamic range.

2, A transmitter is operating on SSB and runs warm while outputting 100W PEP. If the same transmitter is switched to RTTY and the output is set to the same 100W peak level, how will the transmitter's temperature likely change?

A. a bit cooler than before

B. considerably hotter than before

C. slightly hotter than before

D. at much the same temperature as before.

3, What is the phase shift of an L-network (series L-shunt C) at resonance?

A: 180

B: -180

C: 90

D: -90

4, Why is knowing the phase shift of an L-network important in RF design, particularly when matching an antenna to a transmission line?

A: It dictates the maximum frequency the network can handle.

B: It determines the physical length of the inductor.

C: It indicates the "orientation" of the load and ensures the desired current/voltage phase relationship.

D: It defines the power rating of the capacitors.
