But those shared bands are not a complete free-for-all: there are
supposed to be limits to the power that transmitters are allowed to
have, precisely to avoid this sort of interference.

Not to the military. How naive of you.

You appear to believe that we are at war with Australia, Tony - I can
assure you that is not the case. The Australian Navy ship caused the
disruption when approaching Wellington, and adjusted frequencies to
rectify the problem - although many found that setups for coverage
required some work to reconnect. Lawrence is correct that there are
supposed to be limits on usage - and the fact that they were able to
move to other spectrum bands suggests that a mistake was made.

It is possible that our free spectrum bands differ from those in
Australia, but all ships approaching New Zealand waters should be
aware of frequencies they should use. Let us hope that it requires the
close attention of our Defence Minister for as long as possible . . .
