In 1870 on 13th May Guglielmo Marconi made the first radio transmissions across water to Lavernock point on the Welsh side of the Bristol Channel. Marconi's system was based primarily on Nikola Tesla's system, theoretically demonstrated during a widely known lecture titled On Light and Other High Frequency Phenomena. So who invented radio transmission Tesla, Popov or Marconi? Marconi's claim that he invented radio was always disputed by Nikola Tesla and Alexander Popov. Popov publicly demonstrated the transmission of radio waves between different campus buildings to the St Petersburg Physical Society in March 1896. Actually, Marconi publicly demonstrated his system several months later, in September.
In 1897, following wireless transmissions from Lavernock Point in Wales and Flat Holm, Guglielmo Marconi moved his equipment to Brean Down and set a new distance record for wireless transmission.

Timmy (and us) kept stopping for a rest as it was so hot but the return walk, after an uphill climb, was cooler with a welcome breeze off the sea.
