Radio Map
MORSE CODE SIGNALS are sent out as
a RADIO BEAM, and you can pinpoint
where you are by listening to the signal.


If you hear an “A” being sent out, you
know you are in one of the 2 “A”
quadrants on the map. If it gets weaker,
you flying out of the quadrant.
Stronger signals are closer in—and then,
when you fly on top of the beam,
there is a
“CONE OF SILENCE.”
