Correct answer: the other callsign followed by your own callsign

Standard operating practice is to identify:

• who you are calling, and then
• who you are

at the start and end of a transmission.

This ensures both stations are clearly identified and helps avoid confusion on the frequency.

• Giving your own callsign first does not clearly indicate the intended recipient.
• Repeating only one callsign does not identify both stations involved.

Therefore, the correct order is the other callsign followed by your own callsign.

Correct answer: B — zulu lima one alpha november

The ITU phonetic alphabet (also called the NATO phonetic alphabet) is the internationally recognised standard for spelling out callsigns and other information over radio. Each letter has a specific phonetic word assigned to it, and these words must be used exactly as defined — not substituted with alternatives, even if they seem similar.

For the callsign ZL1AN:

• Z = Zulu

• L = Lima

• 1 = One

• A = Alpha

• N = November

• Option A is wrong — "Zanzibar" and "London" are not ITU phonetic alphabet words; they are older British military alternatives no longer in standard use.

• Option C is wrong — "Able" and "Nancy" are from an outdated phonetic alphabet, not the current ITU standard.

• Option D is wrong — "Able" is incorrect for A, and "Niner" is the pronunciation for the digit 9, not the letter N.

Therefore, only Option B correctly uses the current ITU/NATO phonetic alphabet throughout for the callsign ZL1AN.

Correct answer: "CQ CQ CQ this is ZL1XXX ZL1XXX ZL1XXX"

The standard and accepted procedure when calling CQ on SSB is:

• call "CQ" several times
• clearly identify your callsign
• repeat your callsign for clarity

This ensures:

• other stations can recognise the call

• your callsign is correctly copied

• The alternative phrasing is less standard.

• Informal or incomplete identification is not correct practice.

Therefore, the accepted call is:

"CQ CQ CQ this is ZL1XXX ZL1XXX ZL1XXX"

Correct answer: perfect intelligibility but very low signal strength

Signal reports use the RST system:

• R (Readability): 1–5
• S (Signal strength): 1–9
• T (Tone): for CW only

A report of 5 and 1 means:

• 5 (readability) = perfectly readable
• 1 (strength) = very weak signal

Therefore, the signal has perfect intelligibility but very low signal strength.

Correct answer: B — victor kilo five zulu xray

The ITU/NATO phonetic alphabet is the internationally recognised standard for spelling out callsigns clearly over radio. Each letter has one correct phonetic word; using non-standard substitutes causes confusion and is contrary to good operating practice.

The correct phonetic words for VK5ZX are:

Character	Phonetic
V	Victor
K	Kilo
5	Five
Z	Zulu
X	X-ray

• A — victor kilowatt five zulu xray is wrong because "Kilowatt" is not the NATO phonetic for K; the correct word is "Kilo."
• C — victor kilo five zanzibar xray is wrong because "Zanzibar" is not the NATO phonetic for Z; the correct word is "Zulu."
• D — victoria kilo five zulu xray is wrong because "Victoria" is not the NATO phonetic for V; the correct word is "Victor."

Therefore, the only phonetically correct rendering of VK5ZX under the ITU/NATO standard is victor kilo five zulu xray.

Correct answer: D — "ZL2ZZZ listening on 6695"

The standard procedure when monitoring a VHF repeater is to identify yourself by callsign first, then state the repeater you are listening on. This format — callsign first, followed by "listening on" and the repeater identifier — is the accepted NZART convention. It immediately tells other operators who is available and on which repeater, without unnecessary repetition or incorrect terminology.

• A — "hello 6695, this is ZL2ZZZ listening" is wrong because "hello" is informal and non-standard; the callsign should come first, not the repeater identifier.
• B — "calling 6695, 6695, 6695 from ZL2ZZZ" is wrong because "calling" implies you are trying to contact the repeater itself, and triple repetition is unnecessary for a routine listening announcement.
• C — "6695 from ZL2ZZZ" is wrong because leading with the repeater number rather than your callsign is non-standard, and omitting the word "listening" leaves the transmission ambiguous.

Therefore, the correct and accepted announcement format is "ZL2ZZZ listening on 6695", with your callsign stated first followed by the repeater identifier.

Correct answer: will be listening for replies 2 kHz higher in frequency

When a DX station says “up 2” on CW, it means:

• the station is transmitting on one frequency
• but listening for replies 2 kHz higher

This is called split operation and is used to:

• manage large pile-ups

• reduce interference on the calling frequency

• It does not refer to sending speed.

• The station is not changing its transmit frequency.

• It is not related to timing.

Therefore, “up 2” means the station is listening 2 kHz higher in frequency.

Correct answer: B — 3 seconds

When using a VHF or UHF repeater, you should pause for approximately 3 seconds between overs (transmissions). This pause serves several important purposes: it allows the repeater's tail timer to reset, it gives other stations an opportunity to break in with urgent traffic or to join the conversation, and it prevents the repeater from locking up continuously with no gaps for other users.

• Half a second is far too brief — the repeater may not have time to drop and reset, and other stations have no practical opportunity to break in.
• 30 seconds is unnecessarily long and would make the conversation awkward and inefficient, wasting repeater access time.
• Several minutes is completely impractical and would effectively block other users from accessing the repeater for extended periods.

Therefore, a 3-second pause between overs is the accepted practice on VHF/UHF repeaters, balancing courtesy to other users with efficient use of the repeater resource.

Correct answer: A — listen first, then ask if the frequency is in use

Before transmitting on any HF frequency, good operating practice (and courtesy) requires you to first listen for a period to confirm the frequency is clear. Because HF propagation can mean you hear stations that others cannot, and vice versa, a channel may appear clear to you but actually be in use. After listening, it is standard practice to ask "Is this frequency in use?" (or send "QRL?" in CW) before calling CQ. This protects ongoing QSOs from interference.

• B — request that other operators clear the frequency: You have no right to demand other operators leave a frequency they are already using; the obligation is on the newcomer to find a clear frequency.
• C — request a signal report from any station listening: A signal report (RST) is exchanged during a QSO, not as a pre-transmission check to see if a frequency is free.
• D — use a frequency where many stations are already calling: Transmitting on a busy frequency without checking only adds interference; calling CQ where others are already active would create a pile-up of conflicting signals.

Therefore, the correct procedure is always to listen first and then ask "Is this frequency in use?" before calling CQ on the HF bands.

Correct answer: your signal into the repeater is strong enough to be noise-free on the output frequency

When a signal fully quiets a repeater, it means the received signal strength at the repeater input is sufficient to eliminate background noise on the repeater’s transmitted output.

In FM systems, increasing signal strength reduces noise until the output audio becomes clear and free from hiss.

• A weak signal would produce noisy audio.
• Modulation level refers to audio amplitude, not signal strength.
• Speaking quietly affects modulation, not receiver noise quieting.

Therefore, fully quieting the repeater means your signal is strong enough to be noise-free on the output frequency.
