🔍 Key Concepts

• DSC (Digital Selective Calling) procedures for urgency calls (MAYDAY vs PAN-PAN) • Role of the DUS (Distress/Urgency/Safety) table/placard and what frequencies/modes your equipment is allowed to auto-select • Differences between J2B (telex/NBDP) and J3E (SSB radiotelephony) emissions and when auto-switching is acceptable

💭 Think About

• For each option, ask: would this automatic switch put my radio on a frequency and emission that my ship is actually authorized and set up to use for distress/urgency/safety traffic? • Think about what the DUS table/placard is there to prevent. Which scenarios show that control working properly, and which show it being bypassed or ignored? • Consider whether it is safer for the set to switch only to combinations (frequency + emission) that are both: (1) on the DUS placard and (2) appropriate for the type of traffic requested (telex vs voice).

✅ Before You Answer

• Verify how your equipment is required to use the DUS table/placard for automatic frequency changes on receipt of DSC distress/urgency/safety calls. • Check which emission designator (J2B vs J3E) is used for TELEX/NBDP traffic and which is used for voice, and match that to what the urgency DSC call is asking for. • Confirm that auto-switching to a non‑placarded or non‑marine band frequency would be considered improper or dangerous.

Question 1 of 20

Which of these would not be a bad outcome of an Urgency DSC call to all vessels specifying an alternate TELEX frequency & emission that cause your transceiver to automatically switch?

The DSC controller decoded the contents of the DSC call and the requested frequency is not on the DUS table/placard but is in the marine band frequencies in the J2B emission.

The DSC controller decoded the contents of the DSC call and the requested frequency is on the DUS table/placard in the J3E emission.

The DSC controller decoded the contents of the DSC call and the requested frequency is on the DUS table/placard in the J2B emission.

The DSC controller decoded the contents of the DSC call and the requested frequency is not on the DUS table/placard, is not in the marine band or the other vessel requested a J3E emission.
