G'day

Thanks very much for the comments and explanations - the web site seems to
indicate that this can be a special set up for emergencies and Michaels
comments suggest it can also be a routine set up at some coast guard
stations. In such a case what is the correct protocol for accessing
information? Do you have to make a request and then continue talking while
the triangulation is carried out - or is it nearly instantaneous? When I was
a kid it took several minutes fiddling with the angle on a ferrite rod
aerial to get a bearing on a radio station. I haven't heard of this facility
in Australian Coast guard stations but will investigate after I understand
the protocol a bit better.

All the best, Peter
