Hi All,
This doesn't answer Andy's query re reduced carrier in the maritime
enviroment but it does offer a reason for using reduced carrier elsewhere.
I recall reading an article many (30+) years ago about a proposal to use SSB
in the VHF/UHF Land Mobile Service. If my memory serves me correctly, the
article came from the UK.
The proposal suggested 10% carrier remained, to enable phase locking the
receiver to the incoming signal, to ensure the receiver was always "tuned
in".
Cheers ... Ray
