Radio Netherlands deliberately puts the delay between the two transmitters
at the same site in the Caribean.  There is interaction between them if
they are broadcasting the same exact thing and one of them shuts down.
As for the BBC and others, that is usually satellite delay.  It depends on
the number of "hops" it takes to get from London to one transmitter or
another.  Most of the strong BBC signals we hear in North America are
comming from RCI and VOA transmitters.
