Module 8 - Digital Selective Calling

Routine Individual DSC Calls

For a routine individual DSC call, select the other station's MMSI, choose routine priority, nominate a suitable working channel, then wait for the acknowledgement. The voice conversation starts on the accepted channel.

DSC is precise, but only if the directory, MMSI, and channel choice are right. A wrong MMSI can call the wrong station or no useful station at all.

Key points

  • Use routine priority for routine traffic.
  • Enter or select the correct MMSI.
  • Nominate an appropriate working channel.
  • Start voice traffic only after acknowledgement and channel agreement.
