Did JC Bose invent the radio?
Bose is known as the father of wireless telecommunication. He had invented the Mercury Coherer, a radio wave receiver that was used by Guglielmo Marconi to build an operational two-way radio. 3. While Marconi was celebrated for his invention, Bose remained unknown to many, as he never patented his work.
What was Marconi’s first message?
On 13 May 1897, Marconi sent the first ever wireless communication over open sea – a message was transmitted over the Bristol Channel from Flat Holm Island to Lavernock Point near Cardiff, a distance of 6 kilometres (3.7 mi). The message read, “Are you ready”.

Radio/Inventors
Guglielmo Marconi: an Italian inventor, proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895.

When did Edwin Howard Armstrong invent FM radio?
Edwin Howard Armstrong created the frequency modulated “FM” radio in 1933. The FM radio could improve the audio signal of radio by controlling static noise levels. In 1965, the first FM Antenna system in the world opened.
When did the first FM radio come out?
Although the history of radio goes all the way back through the 18 th century, it wasn’t until 1965 that the first radio invented for entertainment emerged.
