Although not mentioned by name in this article, the radiotelephone equipment being tested by the U.S. Navy was provided by Lee DeForest. The Outlook, October 12, 1907, page 279:
Wireless Telephones at Sea
The installation of wireless telephones on war-ships by the Navy Department, not to supersede but to supplement wireless telegraphy, is a most interesting experiment, significant of the possibilities of combination which the appliances for the transmission of power, light, heat, and language offer in ways as yet barely suspected. Two battle-ships, the Connecticut and Virginia, have already been equipped with telephones, and it is understood that all the battle-ships which are to go to the Pacific in December will be fitted up in this way, if there is sufficient time. Wireless telephonic communications between two battle-ships have been heard distinctly at a distance of twenty-two miles. It was shown that ships equipped with the wireless telegraph, but not with the wireless telephone, could hear through ordinary telephone receivers what was said in the transmitter of telephones on other ships. Conversational tones were audible through the transmitter of the wireless telephone to operators on ships on which the ordinary telephone receiver was attached to the wireless telegraphic instrument. At a distance of eleven miles communications were so distinctly heard that they were immediately reported back verbatim. On the Connecticut the experimenter placed a phonograph in front of his telephone transmitter and then played a number of musical compositions. At the conclusion of each piece the wireless telegraphic operators on the other ships, miles distant, telegraphed to the Connecticut the titles of pieces which had just been played on that boat. It is idle to comment on the marvelous character of achievements which make the inventions of the story-tellers in the Arabian Nights seem probable, and Jules Verne a matter-of-fact recorder of every-day achievements. The practical possibilities of these mysterious ways of communicating the voice and messages promise in the near future a practical reduction of the remaining perils of sea travel. When fogs can be penetrated in every direction by human voices, and the positions of ships accurately located, icebergs and derelicts will remain almost the only menaces of life and property on the high seas.
