Shortwave radio were required. It was also difficult to beam the radio wave directionally with long wave, resulting in a major loss of power over long distances. Prior to the 1920s, the shortwave frequencies above 1.5 MHz were regarded as useless for long distance communication and were designated in many countries for amateur use. Guglielmo Marconi, pioneer of radio, commissioned his assistant Charles Samuel Franklin to carry out a large scale study into the transmission characteristics of short wavelength waves and to determine their suitability for long distance transmissions. Franklin rigged up a large antenna at Poldhu Wireless Station, Cornwall, running on
Alexander Bain (inventor) restored in 1959. The headstone had a fallacious date of death (1876) which was later corrected to 1877. JD Wetherspoons pub in Wick, close to where Alexander Bain served his apprenticeship, is now named 'The Alexander Bain' after the inventor. Also, as a tribute to his inventions, the main BT building in Glasgow is named Alexander Bain House. One of the earliest examples of an electrically impulsed pendulum clock is on display at the Deutsches Uhrenmuseum. In 2016 he was awarded the Technology & Engineering Emmy Award "for his pioneering work in the transmission of images". Alexander Bain (inventor) Alexander
