IMD Registration


International Marconi Day celebrates the huge part Guglielmo Marconi played in the invention of radio. 

IMD is a 24 hour amateur radio event that is held annually to celebrate the birth of Marconi on 25 April 1874. The event is usually held on the Saturday closest to Marconi’s birthday and in 2023 it will be held on 22nd April.

The purpose of the day is for amateur radio enthusiasts from around the world to make contact with Historic Marconi Sites using communication techniques similar to those used by Marconi himself.
