RTTY: Radio Teletype Operating Mode Resources
Find guides, software, and contest information for RTTY, a popular digital mode for ham radio communication.
RTTY, or Radioteletype, is a classic digital mode that remains popular among amateur radio operators for its robust performance, especially during contests and DX operations. Hams use RTTY to exchange text messages, often at speeds of 45 or 75 baud, making it a reliable choice for QSOs even when propagation is challenging. It's a mode that combines historical significance with modern software tools, attracting operators who enjoy both the technical challenge and the unique sound of its shifting tones.
Operators interested in RTTY can find resources covering everything from basic setup guides to advanced contesting strategies. Many hams use software like MMTTY for decoding and encoding, often integrated with logging programs for contest operations. There are also dedicated RTTY contest calendars and world ranking lists for major events like the JARTS RTTY Contest, helping contesters track scores and rules. Additionally, resources are available for building sound card interfaces and understanding how to work RTTY pileups effectively.
