421C down in Washington State

That would be an Adcock Range or 4 course range. The NDB is
just a radio station that is used by the ADF as a source for
the directional loop antenna to point to.
BTW, it was .- and -. (A and N) and when on course all you
heard was a steady ____________

You flew a little to the side of the leg and thus hear a
steady tone with a slightly audible A in the background.
There was even a reed needle that could be panel ,mounted
and would vibrate. That was high tech in 1940.

Jim, you really don't catch the jokes very well, do you?

I was joining the thread after deleting previous posts to
clean up my hard drive. Had thousands of mostly unwanted
stuff. Sorry if I wasn't looking for a joke in a "serious"
subject.

But I guess I can be described as a stick in the mud, a wall
flower, a geek, dork, dumb-ass,slow, out of touch, in a rut,
but hey, nobody's perfect.

Ok, I guess I remember my grandfather telling me about those things.

AMC ran the John Wayne/Ernest Gann classic THE HIGH and the
MIGHTY last week. I noticed that the GCA controller told
them they were below the GS, but then they showed the ILS
indicator and they had a 1/2 scale fly down.
