We could invent a gadget that could do the same thing.
We could leave our VHF on a channel not much used, with our gadget hooked
up to the external speaker output, then whistle as we clicked the
push-to-talk on our pocket VHF to trigger our homing anchor light.
On the other hand, we could use an old Indian trick that I learned about on
cardboard separating layers of Shredded Wheat when I was 5 years old.
Called "Ingin'nuity", the cards featured various techniques supposedly used
by Native Americans. The one that stood well for me for all my life was
the technique of looking behind me occasionally when traveling a trail for
the first time, especially at intersections, to "photograph" in my mind
what the return trip will look like.
