Ham Radio General Class Test FREE Ham Radio General License Questions and Answers 3

Question 1

What type of propagation allows HF radio signals to travel beyond line-of-sight distances?

Accepted Answer

Skywave propagation via the ionosphere

Answer

Skywave propagation refracts HF signals off ionospheric layers, enabling long-distance communication.

Question 2

What is the minimum distance a General class operator should maintain from the boundaries of an Extra class exclusive frequency segment?

Accepted Answer

Stay well clear to avoid interference and ensure compliance

Answer

Operators should stay well clear of sub-band edges to ensure their signal bandwidth does not encroach into restricted segments.

Question 3

Which emission type is FT8, a popular digital mode used on HF bands?

Accepted Answer

A weak-signal digital mode using 8-tone frequency shift keying

Answer

FT8 is a weak-signal digital protocol that uses 8-tone frequency shift keying in 15-second transmission cycles.

Question 4

What must a General class licensee do before transmitting on a new frequency?

Accepted Answer

Listen to ensure the frequency is not already in use

Answer

Good operating practice and FCC rules require listening first to avoid interfering with stations already using the frequency.

Question 5

What is the function of an antenna tuner (transmatch)?

Accepted Answer

To match the impedance of the antenna system to the transceiver output

Answer

An antenna tuner adjusts the impedance seen by the transmitter to provide an acceptable match for efficient power transfer.
