Ballybunion
Additional facilities were constructed at Ballybunion, Ireland in 1914 and employed during World War I. In March 1919, the first Marconi broadcast of voice by longwave radio, made from Marconi's station YXQ at Ballybunion using vacuum tubes instead of the spark gap transmitters formerly used in radiotelegraph operation, was heard as far as Chelmsford and Louisburg, Nova Scotia.
Due to destruction caused by the Irish Civil War in 1922, traffic formerly carried at Clifden was permanently redirected via Caernarvon, Wales, a link which remained in service until replaced by more modem technology in the 1930s. The Marconi Station at Ballybunion was also to cease operation.
