The tone changed if you drifted off the beam. Some of the old timers
here can explain this a lot better than me since I didn't start
flying until the late 1970's.


As I think about it, the Morse that was transmitted was a series of A's and N's.
I can't remember any more than that about it.

Four wide angle beams. Two quadrants broadcast A and two broadcast
N--one is dot/dash, the other is dash/dot (don't remember which is A
and which is N.)

When the beams overlapped, defining the published course you got a
steady tone. Veer to one side you began to discriminate A, veer off
course the other way and you got N. One course---hummmmmmmmmm.
