7-A-026: DSC Format & Info Sent
7-26D1:
What sequence best describes an MF-HF DSC Distress menu transmission?
A string of dots to stop the DSC scanner, Distress priority code, vessel position & time, emission for follow-on communications, DSC frequency.
Vessel name, Distress priority code, vessel position & time, nature of Distress.
A string of dots to stop the DSC scanner, vessel MMSI, vessel position & time, nature of Distress, frequency for follow-on communications.
Vessel MMSI, frequency & emission for follow-on communications, vessel position & time, Distress priority code.
7-26D2:
MF-HF DSC alerts are transmitted using what emission type?
J2B to ensure compatibility with DSC receivers.
J3E to ensure correct voice follow-on frequencies are used.
F1B to ensure correct SITOR (NBDP) follow-on frequencies are used.
A3E to achieve the best transmission range.
7-26D3:
When sending a DSC call:
Vessel’s position will automatically be sent if the vessel is sending a “Distress Hot Key” alert.
Vessel’s position will automatically be sent with DSC calls specifying an alternate frequency.
Vessel’s MMSI will indicate its ocean region and vessel position.
Vessel's MMSI and position will automatically be sent for all types of DSC calls.
7-26D4:
DSC transmissions are encoded:
Using a ten-bit error detecting code.
Using J3E mode for proper follow-on communications.
Using F1B mode to ensure proper reception.
Using J2B mode for correct transmission.
7-26D5:
DSC transmissions are received:
Using digital decoding by the DSC controller.
Using voice or TELEX modes as appropriate.
Using J3E or H3E modes as appropriate.
Using F1B and/or J2B decoding by the transceiver.
7-26D6:
Properly formatted MF-HF DSC transmissions can request which of the following emissions for follow on communications?
J3E/H3E voice emissions
J3E/H3E telex emissions
F1B/J2B voice emissions
J3E/H3E voice emissions
