Poor radio communication doesn’t just confuse; it can slow down operations, create safety risks, and undermine your team’s confidence in you. Whether you’re coordinating site security, managing crowd control, or working an event, bad habits on the radio can have real consequences.

Good radio etiquette is a professional standard. It’s what separates teams that communicate with confidence from those that talk over each other, miss important communications, or send unclear messages.

This guide covers the essential dos and don’ts of good two-way radio etiquette which will make a real difference when using your two-way radio or walkie-talkie.

The Dos of Radio Communication

Follow these practices to keep your communications clear, professional, and effective.

✅ Plan your message before you transmit

Think for a moment before you press the Push-To-Talk (PTT) button. Know what you need to say, to whom, and why. Unnecessarily long or imprecise radio calls waste time and may delay others from transmitting. A few seconds of preparation can avoid confusion and follow up clarification calls.

✅ Identify yourself and your recipient clearly

Calls should begin with who you’re calling and who you are, e.g.

“Main Security Gate, Jack.”

This removes ambiguity instantly and helps the recipient prepare to respond, e.g.

“Jack, Main Security Gate, pass your message.”

Subsequent transmissions then only need your own callsign at the end, e.g.

“Lock down access immediately, Jack.”

✅ Keep messages brief and clear

Radio communication follows the 5 Cs of effective transmission:

Concise — say what you need in as few words as possible

Clear — use plain, unambiguous language

Confident — speak steadily and with authority

Controlled — manage the pace and tone of your delivery

Capable — practise regularly to improve your radio manner

✅ Wait for the channel to be clear

Before transmitting, listen briefly to confirm no one else is mid-message. Broadcasting over another user’s transmission can mean neither message gets through clearly.

✅ Use the correct radio terminology

Thanks to film and television, phrases like “over” and “out” are commonly used, however, they are unnecessary.

Know the language your team uses. Shortcut terms and phrases can be beneficial, as long as everyone understands what they are, so avoid inventing new ones on-the-fly.

✅ Hold the PTT button correctly

When you press the Push-To-Talk (PTT) button, allow about half a second before speaking, then hold for half a second after you’ve finished your message. Speaking immediately after pressing the PTT often clips the first word, and releasing the button too early cuts off the end of your message. This small habit makes a noticeable difference to transmission quality.

The Don’ts of Radio Communication

Avoiding these common mistakes will improve communication quality across the whole team.

❌ Don’t use the radio for unnecessary conversation

Radio channels are shared, working tools. Side conversations, informal chat, and non-essential messages create noise, block the channel, and frustrate other users.

❌ Don’t interrupt unless it’s urgent

Breaking into someone else’s transmission is only acceptable in an emergency. If you need to interrupt, use the phrase “Break, break” to signal urgency before speaking.

❌ Don’t use jargon or informal slang

Unless specific terminology has been agreed and briefed across your team in advance, avoid jargon. Using phrases that others don’t recognise or that have different meanings in different contexts leads to misunderstanding, particularly in high-pressure situations.

❌ Don’t shout

Speaking loudly into a radio often distorts the audio and makes the message harder to understand, not easier. Speak at a steady, clear, moderate volume.

❌ Don’t leave transmissions open

An open or stuck PTT button blocks the channel for everyone else. Always release cleanly after your message and check your equipment regularly to prevent accidental broadcasts.

❌ Don’t overuse emergency terms

Phrases like “Mayday,” “Emergency” and other distress signals are reserved for life-threatening situations. Emergency protocols should be defined and communicated across teams before picking up a radio.

FAQ’S

What information should you include in a radio message?

A good radio message includes who you are calling, who you are, the relevant information (location, situation, or instruction). Keep it factual, brief, and free of unnecessary detail.

When should you use the phonetic alphabet on a radio?

Use the phonetic alphabet (Alpha, Bravo, Charlie…) when spelling out names, postcodes, registration numbers, or any information where individual letters could be misheard. It is especially important in noisy environments or where signal quality is reduced.

What should you say when starting a radio transmission?

Begin by identifying the recipient and yourself: “[Recipient], [Your Name].” Wait for acknowledgement before delivering your message. This structure ensures the right person is listening and ready before you transmit.

Can you use a two-way radio in an emergency?

Yes, two-way radios are widely used in emergency and critical communication scenarios because they don’t rely on mobile networks.

What are the most common mistakes people make on a radio?

The most frequent issues include failing to identify yourself, talking over others, using unclear language or unrecognised jargon, releasing the push-to-talk button too early, and leaving channels open accidentally.
