Wireless Telegraphy

Wireless telegraphy, also known as spark-gap telegraphy, was the first form of wireless communication used on ships. It allowed ships to communicate with each other and with shore stations using Morse code. The system used a spark gap transmitter that produced a series of radio waves that could be detected by a receiver on another ship or shore station.

Wireless telegraphy was a significant improvement over the traditional telegraph system because it allowed ships to communicate over long distances without the need for a physical wire. However, the system was not without its flaws. It was prone to interference from other radio signals, and the quality of the signal deteriorated over long distances.

Radio Telephone Systems

Radio telephone systems were the next evolution of wireless communication on ships. These systems allowed ships to communicate using voice instead of Morse code. The first successful radiotelephone transmission was made by Reginald Fessenden in 1900.

Radio telephone systems were a significant improvement over wireless telegraphy because they allowed for real-time communication between ships and shore stations. The system used amplitude modulation (AM) to encode the voice signal onto a radio wave. The receiver on the other end would then decode the signal and convert it back into sound.

In the early days of radiotelephone systems, the quality of the signal was poor, and the range was limited. However, as technology improved, the quality and range of the system improved, making it the primary form of communication on ships.

Overall, the emergence of radio communications revolutionized communication on ships, allowing for real-time communication over long distances. The wireless telegraphy system paved the way for the radio-telephone system, which allowed for voice communication.
