My recollection based on some long-ago reading was that this applied to stations primarily along the two coasts,
going inland some distance, and then also to any clears which were further inland but easily audible at the coasts,
and it also applied - particularly on the Pacific coast to actually going silent overnight. The intent was to minimize
enemy use of these AM radio signals as homing beacons such as was done in the attack on Pearl Harbor.

(Apologies for any cross-posting)
I'm delving into the history of a little-known FCC mandate
to U.S. Broadcasters, to reduce transmitter operating power
during World War II. The power reduction went into effect in
1942 and was lifted in 1945.
Little seems available through normal search engines so I'm
asking readers if they can supply anecdotal or factual
references that might help us flesh out this story.
Anything you can add would be useful!
