The Wave Transmitter was a radio transmitter/receiver, described in a patent by Roberto Landell de Moura in 1904, capable of transmitting audio via radio waves as well as light (similar to a photophone). It was developed after many years of Landell de Moura experimenting with multi-function devices that were combinations of megaphones, photophones, and radio telegraphs.
