would you like a fact sheet on radio comms to enable the ease of communicating over the airwaves?
Rapier, there is a list of basic procedure that everyone can follow:Radio voice procedure
Everything ends with either OVER or OUT, never OVER and OUT
OVER My transmission is over and I expect a reply
OUT My transmission is over and I do not expect a reply
I SAY AGAIN Used by sender when making repetitions for emphasis
ROGER Message received loud and clear and will be acted upon as necessary
I SPELL Used when spelling out a word or letter group, except in grid references
GRID Used before any grid reference
FIGURES Used before groups of figures sent digit by digit, except in the case of call signs, grid references and time checks
TIME CHECK Request for a quick time check
Examples: "My position is GRID TWO EIGHT ONE SIX SIX NINE. OVER"
Discipline
• Only one station can speak at a time
• Listen before speaking to ensure that the channel is clear.
• Don’t cut in on other transmission. Allow for other transmissions where only one of the stations in a conversations can be heard by you.
• Pause after pressing the PTT (press to transmit) switch to prevent your first words not being transmitted properly.
• Pause at the end of a conversation.
General
• Identify yourself at the beginning of each transmission. – THIS IS
• Keep all communications as short as possible.
• Be careful of what you say on the net - everyone can hear you.
Messages
When making the initial contact, the transmitting station must first identify the station he is trying to contact, then identify himself. Following this standard means that the first name heard on the net, is the one that has to reply to the call.
Example Bravo wants to speak to Alpha – ALPHA from BRAVO, MESSAGE
Prowords used during initial contact:
THIS IS Indicate the identity of the calling station
RADIO CHECK Used by any station when calling for a report of how he is heard by other stations
UNKNOWN CALLSIGN The identity of the call sign I am calling or replying to is unknown to me.
The proword OVER must be used during all ongoing messages to indicate a break in transmission.
The conversation is terminated with the proword OUT.
Prowords used during and at the end of the conversation:
OVER My transmission is over and I expect you to reply on this subject.
SEND You have permission to transmit your message. Has the same meaning as OVER.
ROGER Message received loud and clear and will be acted upon as necessary. Used with a suffix, e.g. "ROGER OVER"
NOTHING HEARD Indication that no signals have been heard from a particular call sign
OUT My transmission has ended and I do not expect a reply.
WAIT OUT I am not ready to receive a message..
Example
Bravo: "Alpha, THIS IS Bravo. Do you copy? OVER"
Alpha: "Bravo, THIS IS Alpha. SEND"
Bravo: “Are you at the target? OVER”
Alpha: “Yes OVER”
Bravo “ROGER OUT”
