I think we can assume for the most part that we will read only our own
signal.  Our signal is keyed to a certain frequency.  If we're really
concerned that intentional interference will be a problem, we can do
something fancy (say amplitude + frequency modulation, or perhaps
modulated frequency modulation), although that would probably require
some rather tricky electronics or a microcontroller or pal on the
beacon (and Malone would probably discourage us from doing such a
