zone of silence

Post by paul.mercer » Wed Aug 21, 2013 9:15 pm

Many years ago I read somewhere that in certain parts of the oceans there was a zone of silence where no radio messages could get through, obviously this was long before satallites etc, is this just a myth?

Submerged submarines can't communicate by radio, except for receiving VLF/ELF transmissions.

As for ships on the surface, long-range radio propagation is due to the signal bouncing off of the ionosphere. :think: Is there a place (perhaps near the magnetic poles) where the ionosphere either is not there or does not reflect RF?
Just because it's stupid, futile and doomed to failure, that doesn't mean some officer won't try it.

During August 1941 the hilfskreuzer Atlantis in crossing the South Pacific did apparently encouter an area where no radio transmission could be heard, a zone with a radius of about 200 to 300 miles.

It appears that two years later the hilfskreuzer Michel, in roughly the same area, also encountered this phenomenon.
