Andre Kesteloot quoted KC5CW:
Other systems exist. The CONELRAD (CONtrol of ELectromagnetic
RADiation) procedure of the
1960s required radio stations to broadcast special announcements, turn
on and off, and vary their
schedules. This was supposed to warn the public while confusing
missiles that might home in on
broadcast signals. CONELRAD was eventually scuttled when targeting
methods became more
sophisticated.
This was a tiny part of an interesting article but solved a 30-year-
old mystery for me. The word Conelrad appears in a 60s Bob Dylan
song (I imagine this was Talking World War 3 Blues but I don't
have my vinyl collection here at work!) and I have always assumed
it to refer to a commercial name, though it's obviously a reference
to something to do with radio. Now I know.
