RTTY Software for Amateur Radio Operators
Find and download software tools for RTTY and other digital modes, compatible with various operating systems and radio setups.
RTTY, or Radioteletype, remains a popular digital mode for amateur radio operators, especially for contesting and DXing on the HF bands. Hams use RTTY to exchange text messages, often in fast-paced QSOs, relying on its robust signal characteristics to cut through noise and interference. While once requiring dedicated hardware teleprinters, modern RTTY operation is almost entirely software-driven, using computer sound cards to encode and decode signals.
This category features a range of software tools designed for RTTY and other digital modes. Operators can find popular multi-mode programs like MixW and Fldigi, which support RTTY alongside PSK31, MFSK, and CW. There are also dedicated RTTY applications such as MMTTY and KWRTTY, known for their robust performance in contests. Many of these programs integrate with logging software and provide features for radio control, simplifying station operation for both casual QSOs and competitive events.
