So which of the three distress frequencies would be used by someone in a lifeboat? Sandy Blaize W5TVW explains. " It depends on where you are.  If you are close to rescue stations (Coast Guard, L.S.S. or whatever.) use 2182, then 500 KHz. then 8364 KHz.   2182 usually has shortest range and is voice only.  Some sets broadcast a two tone distress signal which rings bridge bells if received.   500 KHz is the best short to medium haul for CW communications. It generates an autoalarm dash sequence along with an SOS and you can also communicate via W/T to any answering ship or station.  8364 KHz was best best for long haul SOS call.  The SOS sequence would be generated but CW two way (W/T) communication was not possible.  No auto alarm equipment was normally carried for use on 8364 KHz ( the the best of my knowledge) only on 500 KHz.

Not all lifeboat sets operated on 2182 KHz., just 500 and 8364 KHz.  Most newer ones operated on all three.  The old “Gibson Girl”  which had no receiver, just a transmitter, only operated on the 8364  (8080? in earlier sets) and 500 KHz only.  These were the ones carried on military aircraft in case of a forced landing at sea for a rescue aid".
