Strange oscillation like helicopter. I've heard before and can't place

it?

Stopped dead at 03:40 exactly. Then the start of Watch America religious
prog. Is this their ID tone? I've never heard the beginnings of this

program
before.


Brain fade time, but I vaguely remember a description in one of the
hobby electronics mags (PE, RE, or Monitoring Times) about a system that
the stations can use to determine which antenna angle gives the best
results to their target area by picking up backscatter and determining
where their signal is going. (Obviously before the time when they could
stick a receiver on the Internet and just listen).

Anybody know any details?
