7-A-032: Distress Relays
7-032A:
Your ship received a Distress relay from the U.S. Coast Guard on DSC freq. 2187.5 kHz. You would acknowledge by radiotelephony on what frequency?
2182.0 kHz
4207.5 kHz
8290.0 kHz
6312.0 kHz
7-032B:
Your ship received a Distress relay on DSC VHF channel 70, on what channel would you reply?
Ch-16
Ch-70
Ch-06
Ch-13
7-032C:
Under what conditions would you relay a DSC Distress alert?
Answers a) and b) are both possible.
If the mobile unit in Distress is incapable of further Distress Alert communications.
If no Coast Station/Mobile Unit acknowledgement is observed.
You should never relay such an alert -- the Coast Station & RCC will do that.
7-032D:
The relay of DSC Distress Alerts:
All of the above
Has completely overburdened the GMDSS system with improperly formatted or inappropriately relayed DSC calls.
Was originally an intended function of the GMDSS system.
Is no longer the preferred method for passing Distress message traffic to an RCC or Coast Station.
7-032E:
Transmission of a Distress alert by a station not in itself in Distress should occur:
In some cases, all of the preceding situations may justify a Distress Alert relay.
When the mobile unit actually in Distress is not itself in a position to transmit the Distress alert.
When the Master or responsible person on the mobile unit not in Distress so decides.
When the responsible person at the Coast Station determines further help is necessary.
7-032F:
Relays of Distress Alerts using DSC may still be done. However, it is now recommended that such relays be done:
By any of the above methods which will effectively provide Distress communications to an RCC or Coast station without further activations of other Mobile Units' DSC controllers.
Only by Inmarsat-C TELEX with Distress Priority.
Only by Inmarsat-B voice or TELEX with Distress priority.
Preferably by MF/HF voice or TELEX directly to the RCC.
