“PROWORDS”
They are standard, easily pronounced words which have been assigned special meanings & greatly speed up message handling on radio networks.
Why use standard ‘Prowords’?
Standardizes radio transmissions so that required information is sent concisely and minimizes the chance of an ERRORoccurring in a message
“This is” - identifies transmitting station“Message” - identifies a formal/official type of transmission
“Over” - it is your turn to talk and I expect you to do so“Send” - send your message
“Roger” - acknowledges reception and understanding of last transmission.
“Wilco” – acknowledge reception and understanding of last transmission
“Over” - it is your turn to talk and I expect you to do so“Send” - send your message
“Roger” - acknowledges reception and understanding of last transmission.
“Wilco” – acknowledge reception and understanding of last transmission
and will perform it
“Out” - identifies the transmission and conversation is over, and that others may use the channel, you DO NOT reply.
“Out” - identifies the transmission and conversation is over, and that others may use the channel, you DO NOT reply.
"Wait” I am pausing for a few seconds, similar to ‘Standby’
"Wait out” I will call you again – a pause for longer then a few seconds. Others may use the channel in the meantime۔

More PROWORD
"Say again/all before/all after, word before/word after”
A request for the sender to re-transmit the transmission or before/after a particular word of phrase
"I say again” I will re-transmit the message or part of the message
"Acknowledge/Acknowledged” Receipt of this message must be acknowledged by the addressee.
“OVER” means “Ihave finished transmitting & I expect your reply,
The frequency is still in use! “
"OUT" means “This conversation is ended –
The frequency is now free for other users and YOU DO NOT reply!”
The phrase "OVER AND OUT" is therefore contradictory and should NEVER be used!
"Read back” The message just sent will be re-transmitted for clarity by the receiving station
"Messagecorrect” The read-back was correct
"Negative” Means NO – more distinctly
"Affirmative” Means YES – more distinctly
“Break, break, break” Interrupt ongoing ‘chit chat’ for a more official/urgent message
“Break, break, break… KF Base this isMobile 1, urgent message, over”
“Emergency, emergency, emergency” Interrupt another c/s transmissions to pass a life threatening message
“Emergency, emergency, emergency, this is Mobile 1, location WP 1 5, convoy under attack, emergency, emergency, emergency, over”
