(April 20, 2009 - js) This year sees the 22nd International Marconi Day (IMD), which marks the anniversary of Guglielmo Marconi's birth, 25 April 1874. This is a 24-hour amateur radio event (taking place on April 25) that is not a contest but an opportunity for radio amateurs around the world to make point-to-point contact with historic Marconi sites and to gain an award for achieving the requisite number of Marconi stations worked. See their website to know all participating IMD stations.
