Marconi long range transmission 125th Anniversary Activity, 1901-2026
Martin (M0MGA) is seen here on 23rd January 2026, 125 years since Senior Marconi completed his experiments on this site. Martin has confirmation from stations in UK and Netherlands, that wireless transmissions can still be long range around the curvature of the earth.
On the 23rd of January, 1901, Guglielmo Marconi carried out his first long range radio transmission experiments, receiving a Morse code signal across the water and 196 miles from St. Catherine’s Point on the Isle of Wight to the Lizard Peninsula in Cornwall, the most southerly point of the English mainland. This was a major step forward because it successfully proved that radio waves could travel beyond the horizon and follow the curvature of the Earth, a feat many scientists of the time thought impossible. The signal travelled 196 miles (315 km), which was more than twice the previous record – also established by Marconi. It was a crucial test that demonstrated the commercial viability for long-distance ship-to-shore communication and spurred Marconi on to attempt an even greater challenge. Marconi referred to this success as his “first little miracle”. It would lead to greater experiments but was absolutely key as it was the very first test to follow “the curvature of the Earth”. Longer distances would follow later in the year and – wireless communication using “radio” waves were here. A major breakthrough discovered on the shores of England that would change the World.
Martin (M0MGA/A) was using his Clansman 321 feeding a TURF25W feeding a grounded grid 813 valve amplifier. He was using the site’s WIBE telescopic mast with an 80M inverted longwire and 49:1 balun, provided by the special event station working in the museum hut with callsign GB125LWS.
