19400216: Radio station WSY, the Civil Aeronautics Authority’s first overseas and foreign airways communications station (OFACS) began regular operations. Capable of two-way radio communications with aircraft flying the Atlantic Ocean, the powerful facility could also communicate with various points in Europe, Bermuda, and Newfoundland. The station’s high-frequency transmitting equipment, located at Bayville, Long Island, initially included four 4-kilowatt transmitters and two 400-watt transmitters. The receiving equipment was spread over 600 acres at Barnegat Light, N.J. A CAA office at La Guardia Field operated both receivers and transmitters by remote control. During World War II, the station proved extremely valuable to U.S. ferrying operations over the North Atlantic. WSY set the pattern for the establishment during the war years of similar overseas communications stations at San Franciso, Seattle, Miami, New Orleans, Anchorage, Honolulu, San Juan, and Balboa, Canal Zone.
