2. Common Q-Codes (Voice Only)
While many Q-codes are used in CW (Morse Code), several are standard in phone (voice) communication.
| Code | Meaning | Usage |
|---|---|---|
| QRG | Frequency | ”My QRG is 14.250 MHz.” |
| QRH | Freq. variation | ”Your QRG is drifting (QRH).” |
| QRM | Man-made interference | ”There is a lot of QRM on the band.” |
| QRN | Static / Natural noise | ”High levels of QRN today.” |
| QRO | High Power | ”I’m going to QRO to 100 watts.” |
| QRP | Low Power | ”I’m running QRP at 5 watts.” |
| QRV | I am ready | ”I am QRV on 40 meters.” |
| QRX | Stand by | ”Please QRX for a moment.” |
| QRZ | Who is calling me? | ”QRZ VU35KB?” |
| QSB | Fading | ”Your signal has some QSB (fading).” |
| QSL | I acknowledge | ”QSL, I copy everything.” |
| QSO | A conversation | ”Thanks for the nice QSO!” |
| QSY | Changing frequency | ”QSY to 14.300 MHz.” |
| QTH | Location/Home | ”My QTH is Rajapalayam.” |
3. Signal Reporting: The RST System
In voice (Phone) communication, we typically only use the R and the S of the RST system.
- R (Readability): Scale of 1 to 5. (5 = Perfectly readable)
- S (Signal Strength): Scale of 1 to 9. (9 = Extremely strong)
Example: “You are 5 and 9 (or 59) into Rajapalayam.”
4. Basic Contact Structure (The “Standardized” Call)
A typical contact usually follows this simple structure:
- Callout: “CQ CQ CQ, this is Victor Uniform Three Five Kilo Bravo calling CQ and standing by.”
- The Exchange: Once someone replies, exchange your Callsign, Signal Report (RST), and QTH (Location).
- Signing Off: “Thank you for the contact. 73 and clear. VU35KB.”
5. Pro-words & Common Jargon
Standard terms used during contacts to keep communication concise and professional.
- 73: “Best regards” (The most common way to sign off).
- CQ: “Calling Any Station” (Used when you seek a contact).
- OM: “Old Man” (Friendly term for any male radio operator).
- YL: “Young Lady” (Term for any female radio operator).
- XYL: “Ex-Young Lady” (Standard term for a radio operator’s wife).
- DX: “Distance” (Refers to a long-distance contact, usually outside your country).
- Rig: Your radio equipment/transceiver.
- Shack: The dedicated room or space where your radio equipment is kept.
- Roger: “I have received your last transmission satisfactorily.”
- Over: “I have finished speaking and am waiting for your reply.”
- Clear: “I am finished with this contact and will be listening/leaving the frequency.”
