Radioteletype (RTTY) is a telecommunications system consisting originally of two or more electromechanical teleprinters in different locations connected by radio rather than a wired link. Radioteletype evolved from earlier landline teleprinter operations that began in the mid-1800s. [1]

Everyday more and more Amateur Radio operators are operating on the HF digital modes, in particular, RTTY. In each RTTY contest I operate, I find about 8-10% new calls that I've not seen before. There are several reasons for wanting to be a RTTY op.

RTTY does not use error correction, handshaking, or synchronizing, all of which slow things down. When quick back-and-forth exchanges are important, RTTY is the mode of choice. Roundtable discussions and nets that would be difficult or slow with other modes are a natural for RTTY.

MMTTY is an application that decodes TTY data and displays the text on your computer using your sound card. Go to the following site and download the MMTTY application. This application will allow you to receive and display the teletype data stream being received by WinAmp. Start your browser or start WinAmp.

2024年10月14日 · RTTY, or Radio Teletype, is a mode of communication that transmits text via radio waves by encoding characters into binary data. It was originally used for telegraphic communication in the early 1900s, but today, it’s widely embraced by amateur radio operators.

2023年8月23日 · RTTY (Also known as Baudot or ITA2) uses the Baudot 5-bit alphabet with FSK to send text messages over the shortwave. This mode is gradually dying out in favor of more robust modes like PSK31 in the amateur service.

2025年2月22日 · RTTY is a way for amateur radio operators to send text messages over radio waves. Instead of using voice, it uses Frequency Shift Keying (FSK). FSK switches between two frequencies to represent different characters. This method allows real-time message transmission. The idea behind RTTY comes from early 20th-century teleprinters.

RTTY uses the Baudot code, invented before radio even existed, and still widely used throughout the world. The Baudot code uses data bits to represent letters, numbers and punctuation, much like your computer does.
