*	LOUISBOURG RECEIVING STATION HIGHLIGHTS
1912 / 1913	Transatlantic business had grown enough to warrant receiving stations being opened at Letterfrack, Ireland, and at Louisbourg, Nova Scotia and the duplex trans-Atlantic service began in 1913
1914 / 1918	(1)The station, with its staff of twenty-five, including censors, was considered to be an important military target, and was guarded by the 94th Highlanders (2) Vacuum tubes were introduced into its receiving circuits, but cautiously at first, keeping the older crystal detectors and Brown available as back-ups at the flip of a switch (3) The receiver house was renovated and modified structurally to reflect these new arrangements
1915	The CW system was used at Louisbourg in a successful experiment to receive CW signals from the U.S. naval radio station in Arlington, Virginia
1916	Electric typewriter punches replaced the hand punch to produce perforated paper tapes
1919	The first east-to-west transatlantic voice transmission was made from a Marconi station in Ballybunion, Ireland (using only three high powered vacuum tubes in the transmitter) to the Louisbourg receiving station
1920	Staff of twenty-two at Louisbourg
1926 / 1927	The long wave transatlantic service with its Cape Breton stations was now obsolete, and was closed (The closing of the Louisbourg station was hastened by a fire that destroyed the receiver building in 1927)
Post 1926 / 1927	The residential buildings were dismantled and used for houses elsewhere
Post 1960	The site of Louisbourg station is now a picnic area in the Fortress of Louisbourg National Historic Park
