This is the station built by Marconi back around 1914. It handled traffic to ships at sea, and cross Atlantic traffic. During WWII it was taken over by the Navy and used to monitor radio transmissions from German U-Boats in the Atlantic. Enigma encoded messages were relayed to Washington for decoding. Direction finding activities, coordinated with other stations along the east coast, would attempt to locate the U-Boats. RCA finally closed the station in the '90's, all marine traffic having moved to satellites. The buildings are now a museum, with exhibits chronicle the site's past.
