Radio operators should aim to transmit all radio messages clearly, accurately and quickly. The goal is to occupy the network frequency for the least possible time in the communication of your message. Therefore, Mrak Hall Coordinators should use simple, jargon-free language in radio communications. For example, to acknowledge receipt of a transmission it is appropriate to say “ok” or “10-4”, or any other phrase that clearly indicates you have received and understood the other user’s transmission.

Procedure Words (Prowords) and Phrases

Prowords and phrases are standard easily pronounced words that have been assigned special meanings to speed message handling on radio networks. They can be used when appropriate and only if you are comfortable with them. However, any word or phrase that is easily understandable and succinct will do. In the Radio Check example above, Bonnie responds using the radio network standard phrase, “I read you loud and clear”. However, for our purposes it is also acceptable to respond “Yes”, or “I hear you fine”, as Roxie did. If you do not know or cannot remember a proword or phrase, it is always preferable to respond in simple English, as you would if conversing in person.

We do not require that users end their transmissions with “Over” or “Out”. For those who wish to use the “Over” and “Out” prowords (as Roxie does in the example), be aware that “Over” is used to state the end of a transmission and indicates that the addressee should reply. “Out” is used to signal the end of the conversation between users. So when responding to a request for information or compliance, a user would say “Over” at the end of their transmissions. This will ensure that the other user will respond and acknowledge their previous transmission. Never say “Over and Out”; it will confuse the other users.
