It's an interesting thought but color me a skeptic. I simply
don't know that two or three receivers per continent would give
enough coverage to be useful. There is a great difference in
propagation between South Florida and North Carolina ... between
Washington/Baltimore and Central Ohio ... between Central Ohio
and Chicago/Milwaukee/Madison, etc. While I don't have any
experience in the rest of the world, I strongly suspect the
same can be said about any two places separated by more than
In addition to the propagation differences, at 80 KHz per
receiver is would take at least three receivers per band to
do the job on phone.
Then there are the issues of antenna design - the antennas
need to be reasonably high performance or you may not be able
to confirm the very thing you need in terms of weak multipliers,
I'm not saying it will not work ... I am saying the effort is
considerably more involved than 10 or 12 receivers scattered
around the world.
