The UK’s Cornish Radio Amateur Club says this event is Saturday, April 25,
Guglielmo Marconi’s birthday. Here is the club’s website,
https://gx4crc.com/ and the IMD Award page: https://gx4crc.com/imd/imd-
award/
On the air, the event is the entire 24 hours of April 25, all bands and modes
for your QSOs, toward an award. Internet modes like EchoLink, DMR and other
digital voice modes will not count for the IMD award. The award certificate,
they say, is very high quality and “well worth obtaining,” the design based on
Marconi’s original stock certificate from 1901. There are 57 registered
stations: https://gx4crc.com/imd/official-imd-stations-2026/ from AO7IMD in
Spain to W2RTM in New Jersey, USA. Many of them, of course are from Marconi-
related sites and museums. Of particular interest for DXers are the Vatican
and the Falklands.
