Radio Teletypewriter Set Group

The Radio Teletypewriter Set Group is a category of equipment within the supply class Teletype And Facsimile Equipment, which belongs to the supply group Communication, Detection, And Coherent Radiation Equipment.

Radio Teletypewriter sets, also known as RTTY sets, are devices used for transmitting and receiving written messages over radio frequencies. They are commonly used in military and commercial applications for long-distance communication.

These sets typically consist of a keyboard or input device for typing messages, a printer or display for receiving messages, and a transmitter and receiver for sending and receiving signals. They use a specific encoding scheme, such as Baudot or ASCII, to convert the typed characters into electrical signals that can be transmitted over radio waves.

Radio Teletypewriter sets are often used in situations where other forms of communication, such as voice or email, may not be feasible or secure. They can be used for sending messages over long distances, even in remote or hostile environments.

In summary, the Radio Teletypewriter Set Group refers to a collection of equipment used for transmitting and receiving written messages over radio frequencies, and it falls under the supply class Teletype And Facsimile Equipment in the supply group Communication, Detection, And Coherent Radiation Equipment.
