Question 1

On which frequencies may a General class licensee transmit SSB voice on the 40-meter band?

Accepted Answer

7.175–7.300 MHz

Answer

General class licensees are authorized SSB phone privileges on 40 meters only from 7.175 to 7.300 MHz. The lower segment (7.025–7.125 MHz) is restricted to CW, RTTY, and data modes for Generals.

Question 2

What is the primary purpose of connecting a dummy load to a transmitter during testing?

Accepted Answer

To absorb RF power without radiating a signal

Answer

A dummy load is a non-radiating resistive device that dissipates RF energy as heat. It allows operators to test and adjust transmitter output without causing interference by transmitting over the air.

Question 3

What is the frequency range of the 15-meter amateur band?

Accepted Answer

21.000–21.450 MHz

Answer

The 15-meter band spans 21.000 to 21.450 MHz. It is a popular DX band for General class licensees and offers good propagation during the daytime, especially near the peak of the solar cycle.

Question 4

What does the acronym VOX stand for in amateur radio operation?

Accepted Answer

Voice-Operated Transmit

Answer

VOX stands for Voice-Operated Transmit. It automatically keys the transmitter when the operator speaks into the microphone, allowing hands-free operation without pressing a push-to-talk button.

Question 5

Which emission mode is most commonly used for slow-scan television (SSTV) transmissions on HF?

Accepted Answer

SSB (single sideband)

Answer

SSTV uses SSB, typically USB, to transmit still images over HF. The audio tones that encode the image are transmitted within the narrow bandwidth of an SSB signal, making it spectrum-efficient for HF use.
