Ham Radio General Class Test Ham Radio General Class Test HF Operating Procedures Questions and Answers 2 — Questions and Answers
Question 1: What is the recommended way to break into an ongoing QSO on HF frequencies?
- Transmit your full callsign during a pause between transmissions (Correct answer)
- Key up immediately and start talking over the existing conversation
- Send a series of dits on CW to get attention
- Transmit 'break break' repeatedly until acknowledged
Correct answer: Transmit your full callsign during a pause between transmissions
The proper procedure is to wait for a pause and then transmit your callsign once to request entry into the conversation.
Question 2: What does the term 'long path' refer to in HF propagation?
- A signal that travels the longer great-circle route around the Earth to reach the destination (Correct answer)
- A signal that bounces more than five times off the ionosphere
- A transmission that uses a long wire antenna
- A QSO that lasts more than one hour
Correct answer: A signal that travels the longer great-circle route around the Earth to reach the destination
Long path refers to propagation where the signal travels the longer way around the Earth rather than the shorter great-circle path.
Question 3: When operating split frequency on HF, what information should you include in your CQ call?
- Your listening frequency or the instruction to call 'up' or 'down' a specific amount (Correct answer)
- Only your callsign and grid square
- The name of the DX entity you are trying to contact
- Your transmit power level and antenna type
Correct answer: Your listening frequency or the instruction to call 'up' or 'down' a specific amount
When operating split, you must tell other stations where you are listening so they transmit on the correct frequency.
Question 4: What is the purpose of a DX cluster in HF operations?
- To share real-time reports of stations heard on the bands so operators can find DX contacts (Correct answer)
- To form a group of stations that transmit simultaneously on the same frequency
- To coordinate emergency communications during disasters
- To assign frequencies to net control stations
Correct answer: To share real-time reports of stations heard on the bands so operators can find DX contacts
A DX cluster is a network that distributes real-time spot reports of DX stations heard on the air.
Question 5: What is the correct procedure when propagation drops out during an HF QSO?
- Wait a reasonable time, try calling again, and if no response, log the contact as lost and try later (Correct answer)
- Immediately increase power to maximum legal limit
- Switch to a higher frequency band without notifying the other station
- Send a distress signal to request relay assistance
Correct answer: Wait a reasonable time, try calling again, and if no response, log the contact as lost and try later
If propagation fades during a QSO, you should wait and retry, and if unsuccessful, attempt to re-establish contact later.
Question 6: What is the standard phonetic alphabet pronunciation for the letter sequence 'CQ' when calling on HF?
- Charlie Quebec (Correct answer)
- Charlie Queen
- Cat Quail
- Charles Quiet
Correct answer: Charlie Quebec
The ITU phonetic alphabet uses 'Charlie' for C and 'Quebec' for Q.
