Thanks to Henry VK2ZHE for the head-up! Fire up your HF rigs this weekend!
The Cornish Radio Amateur Club (GX4CRC), organisers of International Marconi Day (IMD), states:
International Marconi Day celebrates the huge part Guglielmo Marconi played in the invention of radio.
International Marconi Day 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 2017 it will be held on 22nd April.
Period of Operation on 22nd April 2017 – 0000 UTC to 2359 UTC
The purpose of the day is for amateur radio enthusiasts around the world to make contact with historic Marconi sites using communication techniques similar to those used by Marconi himself.
The Hornsby And Districts Amateur Radio Club will be operating VK2IMD for the event. The HADARC page for the event states (paraphrased):
VK2IMD is the only IMD station in Australia. It gains this privilege because of the wireless communication experiments conducted personally between Ernest Fisk and Marconi in 1918. Fisk established the Australian end of the experiment at his home in Wahroonga, giving the historical significance to our local area.
Operation starts at 00.00 UTC and finishes 23.59 UTC Saturday 22 April. This is from 10.00 local time Saturday morning to 09.59 local time Sunday morning.
Operation is on all HF bands and 160m, permitted modes are CW, SSB, AM, and available digital modes only.
