Ham Radio Technician Test Operating Procedures & Etiquette 4 — Questions and Answers
Question 1: Why is it important to pause briefly before transmitting after another station finishes speaking on a repeater?
- To allow the repeater's courtesy tone to sound and reset (Correct answer)
- Because FCC rules require a mandatory pause
- To give time for other stations to log the transmission
- To allow interference to clear from the previous transmission
Correct answer: To allow the repeater's courtesy tone to sound and reset
Waiting for the repeater's courtesy tone ensures the repeater has fully reset and is ready for the next transmission, preventing kerchunking.
Question 2: What is 'tail-gating' in repeater operation and why is it discouraged?
- Transmitting immediately after another station before the repeater resets, causing missed audio (Correct answer)
- Adjusting your squelch while another station is transmitting
- Following another mobile station on a highway while operating radio
- Signing off too quickly after a contact
Correct answer: Transmitting immediately after another station before the repeater resets, causing missed audio
Tail-gating causes the beginning of your transmission to be cut off because the repeater hasn't fully reset, resulting in missed communication.
Question 3: When is it appropriate to use 10-codes (like 10-4) on the amateur radio bands?
- Whenever they improve communication clarity
- On VHF/UHF frequencies only
- They are not recommended; plain language or Q-codes are preferred (Correct answer)
- Only when communicating with public safety agencies
Correct answer: They are not recommended; plain language or Q-codes are preferred
Ten-codes are specific to public safety and land mobile radio; amateur operators are encouraged to use plain language or standard Q-codes instead.
Question 4: What does the term 'full quieting' mean when receiving a signal on FM?
- The operator has stopped transmitting
- The received signal is strong enough to completely suppress background noise (Correct answer)
- The repeater has gone into a quiet mode
- The operator is using noise-canceling equipment
Correct answer: The received signal is strong enough to completely suppress background noise
Full quieting means the incoming signal is strong enough to fully engage the FM limiter, producing perfectly clean audio with no background hiss.
Question 5: What is the proper procedure when you want to make contact on a calling frequency like 146.520 MHz simplex?
- Establish your full QSO on 146.520 MHz and stay there
- Call CQ on 146.520, then move to another simplex frequency to have the contact (Correct answer)
- Use 146.520 as a net control frequency only
- Only use 146.520 MHz for emergency communications
Correct answer: Call CQ on 146.520, then move to another simplex frequency to have the contact
Calling frequencies like 146.520 MHz are meant for initiating contact; once answered, operators should move to a clear working frequency.
Question 6: What is the correct way to handle a disagreement or dispute with another operator on the air?
- State your position firmly and repeatedly until the other operator agrees
- Escalate power to ensure your signal dominates the frequency
- Handle it calmly and briefly on-air, or take it off-air entirely (Correct answer)
- File a complaint with the repeater trustee immediately on-frequency
Correct answer: Handle it calmly and briefly on-air, or take it off-air entirely
Amateur radio etiquette calls for calm, brief resolution of disagreements or moving discussions off the air to avoid monopolizing a frequency.
Question 7: What is meant by the term 'rubber duck' in amateur radio?
- A flexible rubber mounting bracket for mobile antennas
- The short flexible antenna that comes standard with handheld transceivers (Correct answer)
- A waterproof housing for portable radio equipment
- A nickname for an inexperienced radio operator
Correct answer: The short flexible antenna that comes standard with handheld transceivers
A 'rubber duck' is the short, flexible helical antenna typically supplied with handheld (HT) transceivers, known for convenience but limited performance.
