This is a short video showing Tony EI5EM keying an old spark-gap transmitter at the Maritime Museum in Dun Laoghaire. He was sending the callsign EI115MAR in celebration of the 115th anniversary of the first occasion on which wireless was used to report live on a sporting event. That event was the Kingstown Yacht Regatta in July 1898. Tony is a member of Howth Martello Radio Group. During this demonstration no antenna was attached.
