Real Distress Messages




OVERVIEW:

Type: Maritime, Ship



Distress messages are real and are sent everyday at its real times when it happened (in one minute window - RX must retuned).

SOS1 is very well described and recorded by N1EA, so I only rewrote it from tape. Fire was extinguished and no one died.
SOS2 happend 30/1/1959 near Greenland. All died. I found some transcripts here: [5][6].
SOS3 Polish ferry M/F JAN HEWELIUSZ/SQIK tragedy was in 1993. She capsized but automatic transmitter was still heard by nearby Ruegen Radio/DHS as well as polish
station Gdynia Radio/SPH. For that reason signal is very weak and QTH is not entered.


Other distress traffic is also present with DDD and XXX procedures:

DDD1 is USCG HONOLULU/NMO DDD SOS (Distress relay). Source [1].
DDD2 DAN DDD of MARIANNEWEHR/DIPJ. Recording exists: [4].
XXX1 was described by NMO radiooperator, but it is not clear for me how real it is. It was Ghana ship and I cannot find that callsign in callbooks.

Also Aircacft SOS exists.
