MODULE 2: Operating Procedures (T2)
This page is part of the N0NJY self-study course for the USA Amateur Radio Technician License.
Operating Procedures (T2)
Overview
Proper operating procedures ensure clear, efficient, and courteous communication on the air. Good procedures reduce confusion, prevent interference, and help emergency messages get through quickly. The Technician exam tests basic voice and repeater operating practices that every new ham must know.
This lesson covers:
- Calling CQ and making contacts
- Repeater operation (including offsets and tones)
- Simplex operation
- Emergency and priority communications
- Use of standard phonetics
- Courtesy and good operating habits
Calling CQ and Making Contacts
To initiate a contact on a clear frequency, call CQ:
- Say: "CQ CQ CQ this is [your call sign] [your call sign], over."
- Repeat your call sign 2–3 times clearly.
- Listen for a response before transmitting again.
When someone answers you, reply with:
- "[Their call sign] this is [your call sign], over."
Keep transmissions short and pause to allow break-ins, especially on repeaters or during nets.
Repeater Operation
Repeaters extend the range of handheld and mobile radios by receiving on one frequency and retransmitting on another.
Key repeater concepts:
- Input frequency (what you transmit on)
- Output frequency (what you listen to / what the repeater transmits on)
- Offset: The difference between input and output
- Common 2-meter offset: +0.600 MHz (600 kHz) or –0.600 MHz
- 70 cm offset: usually ±5.000 MHz
- CTCSS (PL) tone: A sub-audible tone required by many repeaters to access them (e.g., 100.0 Hz, 88.5 Hz)
- Courtesy tone: A short beep or tone after each transmission to indicate the repeater has dropped
Always listen before transmitting. Say your call sign and wait for the courtesy tone before continuing.
Simplex vs. Repeater Operation
Simplex means transmitting and receiving on the same frequency (direct radio-to-radio contact).
Use simplex when:
- Both stations can hear each other directly
- You want to free the repeater for others
- Participating in a local net or event
Repeater use is preferred when simplex range is insufficient.
Emergency and Priority Communications
In an emergency, break into a conversation politely but firmly:
- Say: "Break break" or "Priority traffic" followed by your call sign
- For immediate life-threatening situations: "Mayday Mayday Mayday" followed by your call sign
Yield the frequency immediately to emergency traffic. Never argue or delay emergency messages.
Phonetic Alphabet
Use standard ITU phonetics when conditions are poor or letters/numbers could be confused:
- A – Alpha B – Bravo C – Charlie D – Delta
- E – Echo F – Foxtrot G – Golf H – Hotel
- I – India J – Juliet K – Kilo L – Lima
- M – Mike N – November O – Oscar P – Papa
- Q – Quebec R – Romeo S – Sierra T – Tango
- U – Uniform V – Victor W – Whiskey X – X-ray
- Y – Yankee Z – Zulu
Numbers are spoken normally except: 5 = "Fife", 9 = "Niner", 0 = "Zero".
Good Operating Habits
- Listen before transmitting (avoid doubling)
- Keep transmissions brief
- Identify at least every 10 minutes and at the end of contact
- Use clear, calm speech
- Avoid profanity, politics, or controversial topics
- Thank other operators and say "clear" when ending a contact
