Rules Of Radio Communication

1) Before you press the transmission button, gather your thoughts about what you are going to say. Many people with radios tend to talk and/or repeat too much. Say what you need to say without unnecessary repeats. Keep in mind that your message should go through the first time – you may not have any opportunity to repeat it.

2) As per Battalion SOP’s Chapter 2, Section 1, Sub Section 2. Communication between members in game SHALL be kept to a minimum to allow leaders to better rally troops during battle.

3) Give the call sign of the unit you are calling first. It will alert the addressee to focus on the incoming message. There might be more listeners and radio network users, so you must let them know that this time there will be a message for them.

4) Introduce yourself by your call sign. Do not use real names or nicknames.

5) Don’t speak too fast, pause after logical phrases. High voice does not guarantee that you will be more readable.

6) Use “OVER” when you finish your message. It notifies the addressee that you finished your portion of information and wait for the response or just ended the transmission (“OUT” word).

7) When you have understood the message, acknowledge the receipt with the words “COPY “, “ROGER” or “ACKNOWLEDGED.” The word “COPY” is preferred.

8) If the caller requires some actions you may use “WILCO” instead of “ROGER” to notify that you WILL COMPLY (=” WILCO”).

9) Answer each call to confirm reception. Use “COPY”, or “ACKNOWLEDGED.”

10) If you do not comprehend the message, do not confirm it. Use “SAY AGAIN”, “REPEAT”, “STAND BY” instead.

11) Whenever a word must be spelled use PHONETIC ALPHABET for each letter. Do not invent your own words – they might be misleading and not comprehensive.

12) Use single, cardinal numbers, do not combine them into bigger numbers.

Call Out

When you want to initiate radio exchange, first you must call out the addressee of your message. To notify the addressee about incoming message call him/her twice, giving his/her call sign:

Example: HQ Command, HQ Command…

Then give your call sign:

Example: This is Squad Alpha 1, OVER.

When you expect the other part to answer, finish your portion of message with a word “OVER”, like in the example above.

Quality of transmission
This is used just to confirm how your message was received you may need to ask about the reception. In this instance we use “RADIO CHECK?” or “HOW COPY?” To ask about general quality of the reception you may also ask “HOW DO YOU READ?

There are two ways of responding to such questions. You may simply answer “COPY LOUD AND CLEAR” (= “LIMA CHARLIE”) or give the answerer the notion of the signal quality by giving the note from 1 to 5.

Example: “COPY 3 by 5″

The meaning of numbers used in assessment over the radio:

1 = Bad (unreadable);
2 = Poor (readable now and then);
3 = Fair (readable but with difficulty);
4 = Good (readable);
5 = Excellent (perfectly readable).

When repeat is needed:
It may happen that due to poor transmission or distracting factors some pieces of information should be repeated to avoid misunderstandings. In that case you may request repeat by saying “SAY AGAIN.”

Likewise, when you want to stress the importance of the message or simply make sure that important data get through, you say your message and then use “I SAY AGAIN” and repeat the message.

EXAMPLE: I need five more minutes, I SAY AGAIN, five more minutes…

A = Alpha             N = November
B = Bravo            O = Oscar
C = Charlie          P = Papa
D = Delta             Q = Quebec
E = Echo               R = Romeo
F = Foxtrot         S = Sierra
G = Golf                T = Tango
H = Hotel             U = Uniform
I = India                V = Victor
J = Juliet            W = Whiskey
K = Kilo                 X = X-Ray
L = Lima                 y = yankee
M = Mike                z = zulu

Numbers in radio transmission

It is a common practice to say numbers with each digit separately. For instance, “CHARLIE TWO-THREE” instead of “CHARLIE TWENTY-THREE.” Additionally, to avoid misunderstandings two numerals are pronounced differently:

4 = [foer]
9 = [niner]
