A few dozen special event stations will take to the air April 26, 0000 UTC to 2359 UTC, to commemorate International Marconi Day (IMD). Among them will be GB4IMD, in Cornwall, England, OE14M, in Vienna, Austria, IY0IMD in Italy, VO1AA, on Signal Hill in St Johns, Newfoundland, VK2IMD in Australia, and WA1WCC on Cape Cod, Massachusetts. All stations planning to participate are urged to register. A list of registered participants is on the IMD 2014 website.
International Marconi Day is a 24 hour Amateur Radio event held annually to celebrate the birth of Guglielmo Marconi on April 15, 1874. IMD is held each year on a Saturday close to Marconi’s birthday, with Amateur Radio stations on the air from around the world, including some Award Stations operating from historically significant sites.
The event is not a contest; it is an opportunity for amateurs around the world to make point-to-point contact with historic Marconi sites using HF communications techniques similar to those used by Marconi, and to earn an award certificate for working or hearing a requisite number of Marconi stations.
