Above is a picture of Tesla's basic design of the radio.

In 1892, Tesla had created the basic design for the radio. Tesla had constructed a radio-controlled boat with a tall antenna, which transmitted radio waves coming from where Tesla was sitting. The boat was controlled by the radio waves. This was the first use of radio waves in America. Originally, an inventor named Guglielmo Marconi claimed all the first patents for the the radio, but it wasn’t until 1943 when Marconi’s patents were proved invalid.
