Module 5 - Routine Calls

Ending Cleanly: OVER, OUT, STAND BY and Readback

Use OVER when your transmission is complete and you expect a reply. Use OUT when the exchange is finished and no reply is expected. Combining them as 'over and out' sends contradictory instructions: one asks for a reply while the other closes the circuit.

STAND BY means the station should wait because you will call again; it does not close the exchange or invite the waiting station to repeat continuously. When you return, identify the station and your own vessel so the renewed call is clear on a shared channel.

Use SAY AGAIN when received words are missing or uncertain, and name the part required where possible. Use CORRECTION for an error in your own current transmission, then give the corrected word or group. Read back only the facts whose accurate receipt matters to the operation.
