PSK31 remains a popular digital mode for amateur radio operators, especially on the HF bands. Hams appreciate PSK31 for its narrow bandwidth, allowing many stations to operate simultaneously, and its robust performance even with low power and challenging propagation conditions. It’s a great mode for casual QSOs, ragchewing, and making DX contacts without needing high-power amplifiers or large antenna arrays.

This category provides a range of software tools for PSK31 operation. Operators can find multi-mode applications like MixW and Fldigi that support PSK31 alongside other digital modes such as RTTY and MFSK. There are also specialized decoders for monitoring PSK31 activity, and programs designed for specific operating systems like DarwinPSK for MacOSX or LinPsk for Linux. Many of these programs integrate logging features and can interface with transceivers for full station control.
