Sec. 2.403  Retransmission of distress message.

    Any station which becomes aware that a mobile station is in distress 
may transmit the distress message in the following cases:
    (a) When the station in distress is not itself in a position to 
transmit the message.
    (b) In the case of mobile stations, when the master or the person in 
charge of the ship, aircraft, or other vehicles carrying the station 
which intervenes believes that further help is necessary.
    (c) In the case of other stations, when directed to do so by the 
station in control of distress traffic or when it has reason to believe 
that a distress call which it has intercepted has not been received by 
any station in a position to render aid.
