OK...
Edgar from Tasmania passed me to this webpage http://www.qsl.net/zl1bpu/CMSK/cmsk.htm showing the CMSK mode. Probably well knows by the old experts :-) 

So what about that mode for very weak signal modes on LF? Pros and Cons?
Is this woth to try above 10000 km distance?

Hi,

Question: why do all those professional services for submarines
down at LF/VLF use MSK and not any kind of that advanced stuff
you are talking about?

As far as I know they are using non-linear transmitters like my
cellphone does.
