http://en.wikipedia.org/wiki/CONELRAD

In doing some research on Civil Defense I ran across the CONELRAD stations.
In Wikipedia's entry there is a statement that hams were required in 1957
and later (presumably until 1963 at least) to check that a major broadcast
station was on the air.

Any old-timers remember this requirement? Was it regularly done by working
hams?
